Hsp60 is targeted to a cryptic mitochondrion-derived organelle ("crypton") in the microaerophilic protozoan parasite Entamoeba histolytica. (1/5843)

Entamoeba histolytica is a microaerophilic protozoan parasite in which neither mitochondria nor mitochondrion-derived organelles have been previously observed. Recently, a segment of an E. histolytica gene was identified that encoded a protein similar to the mitochondrial 60-kDa heat shock protein (Hsp60 or chaperonin 60), which refolds nuclear-encoded proteins after passage through organellar membranes. The possible function and localization of the amebic Hsp60 were explored here. Like Hsp60 of mitochondria, amebic Hsp60 RNA and protein were both strongly induced by incubating parasites at 42 degreesC. 5' and 3' rapid amplifications of cDNA ends were used to obtain the entire E. histolytica hsp60 coding region, which predicted a 536-amino-acid Hsp60. The E. histolytica hsp60 gene protected from heat shock Escherichia coli groEL mutants, demonstrating the chaperonin function of the amebic Hsp60. The E. histolytica Hsp60, which lacked characteristic carboxy-terminal Gly-Met repeats, had a 21-amino-acid amino-terminal, organelle-targeting presequence that was cleaved in vivo. This presequence was necessary to target Hsp60 to one (and occasionally two or three) short, cylindrical organelle(s). In contrast, amebic alcohol dehydrogenase 1 and ferredoxin, which are bacteria-like enzymes, were diffusely distributed throughout the cytosol. We suggest that the Hsp60-associated, mitochondrion-derived organelle identified here be named "crypton," as its structure was previously hidden and its function is still cryptic.  (+info)

Carbon 13 NMR study of nonenzymatic reactions of pyridoxal 5'-phosphate with selected amino acids and of related reactions. (2/5843)

Carbon 13 nuclear magnetic resonance spectroscopy has been used to monitor the nonenzymatic reactions of pyridoxal 5'-phosphate with glycine, alanine, valine, serine, and with several other model compounds. Isotopically enriched amino acids were employed so that low concentrations could be utilized while still allowing relatively rapid acquisition of spectral data. The results for alanine and serine are particularly noteworthy in that alanine is deaminated to pyruvate and pyruvate is aminated to alanine, but contrary to the enzymatic reactions of various serine dehydratases wherein serine is converted to pyruvate, the nonenzymatic reaction utilizing serine results in hydroxypruvate rather than pyruvate formation. In the reverse reaction, hydroxypyruvate is aminated to serine but very inefficiently relative to the amination of pyruvate to alanine. The experimental results have been formulated into a proposed reaction mechanism for deamination of amino acids by pyridoxal-P.  (+info)

Presence of the vesicular inhibitory amino acid transporter in GABAergic and glycinergic synaptic terminal boutons. (3/5843)

The characterization of the Caenorhabditis elegans unc-47 gene recently allowed the identification of a mammalian (gamma)-amino butyric acid (GABA) transporter, presumed to be located in the synaptic vesicle membrane. In situ hybridization data in rat brain suggested that it might also take up glycine and thus represent a general Vesicular Inhibitory Amino Acid Transporter (VIAAT). In the present study, we have investigated the localization of VIAAT in neurons by using a polyclonal antibody raised against the hydrophilic N-terminal domain of the protein. Light microscopy and immunocytochemistry in primary cultures or tissue sections of the rat spinal cord revealed that VIAAT was localized in a subset (63-65%) of synaptophysin-immunoreactive terminal boutons; among the VIAAT-positive terminals around motoneuronal somata, 32.9% of them were also immunoreactive for GAD65, a marker of GABAergic presynaptic endings. Labelling was also found apposed to clusters positive for the glycine receptor or for its associated protein gephyrin. At the ultrastructural level, VIAAT immunoreactivity was restricted to presynaptic boutons exhibiting classical inhibitory features and, within the boutons, concentrated over synaptic vesicle clusters. Pre-embedding detection of VIAAT followed by post-embedding detection of GABA or glycine on serial sections of the spinal cord or cerebellar cortex indicated that VIAAT was present in glycine-, GABA- or GABA- and glycine-containing boutons. Taken together, these data further support the view of a common vesicular transporter for these two inhibitory transmitters, which would be responsible for their costorage in the same synaptic vesicle and subsequent corelease at mixed GABA-and-glycine synapses.  (+info)

Multiplex sequence analysis demonstrates the competitive growth advantage of the A-to-G mutants of clarithromycin-resistant Helicobacter pylori. (4/5843)

Clarithromycin resistance in Helicobacter pylori is due to point mutation within the 23S rRNA. We examined the growth rates of different types of site-directed mutants and demonstrated quantitatively the competitive growth advantage of A-to-G mutants over other types of mutants by a multiplex sequencing assay. The results provide a rational explanation of why A-to-G mutants are predominantly observed among clarithromycin-resistant clinical isolates.  (+info)

The role of proline and glycine in determining the backbone flexibility of a channel-forming peptide. (5/5843)

Alamethicin is a helical 20-amino acid voltage-gated channel-forming peptide, which is known to exhibit segmental flexibility in solution along its backbone near alpha-methylalanine (MeA)-10 and Gly-11. In an alpha-helical configuration, MeA at position 10 would normally hydrogen-bond with position 14, but the presence of proline at this position prevents the formation of this interhelical hydrogen bond. To determine whether the presence of proline at position 14 contributes to the flexibility of this helix, two analogs of alamethicin were synthesized, one with proline 14 replaced by alanine and another with both proline 14 and glycine 11 replaced by alanine. The C-termini of these peptides were derivatized with a proxyl nitroxide, and paramagnetic enhancements produced by the nitroxide on the Calpha protons were used to estimate r-6 weighted distances between the nitroxide and the backbone protons. When compared to native alamethicin, the analog lacking proline 14 exhibited similar C-terminal to Calpha proton distances, indicating that substitution of proline alone does not alter the flexibility of this helix; however, the subsequent removal of glycine 11 resulted in a significant increase in the averaged distances between the C- and N-termini. Thus, the G-X-X-P motif found in alamethicin appears to be largely responsible for mediating high-amplitude bending motions that have been observed in the central helical domain of alamethicin in methanol. To determine whether these substitutions alter the channel behavior of alamethicin, the macroscopic and single-channel currents produced by these analogs were compared. Although the substitution of the G-X-X-P motif produces channels with altered characteristics, this motif is not essential to achieve voltage-dependent gating or alamethicin-like behavior.  (+info)

NMDA receptor characterization and subunit expression in rat cultured mesencephalic neurones. (6/5843)

1. NMDA-induced changes in free intracellular Ca2+ concentration ([Ca2+]i) were determined in individual cultured rat mesencephalic neurones by the fura-2 method. mRNA expression encoding NMDA receptor subunits (NR1, NR2A-D) was examined by RT-PCR. 2. NMDA (1-100 microM, plus 10 microM glycine) induced a concentration-dependent increase in [Ca2+]i (EC50 = 5.7 microM). The effect of NMDA was virtually insensitive to tetrodotoxin (0.3 microM) and nitrendipine (1 microM), but dependent on extracellular Ca2+. 5,7-Dichlorokynurenic acid (10 microM), a specific antagonist at the glycine binding site on the NMDA receptor, abolished the NMDA response. 3. Memantine, an open-channel blocker, and ifenprodil, a preferential non-competitive NR1/NR2B receptor antagonist diminished the NMDA effect with an IC50 value of 0.17 and 1 microM, respectively. Ethanol at 50 and 100 mM caused about 25 and 45%-inhibition, respectively. 4. Agarose gel analysis of the PCR products followed by ethidium bromide fluorescence or CSPD chemiluminescence detection revealed an almost exclusive expression of the NR1 splice variants lacking exon (E) 5 and E22. The 3' splice form without both E21 and E22 exceeded that containing E21 by approximately 4 fold. The relative amounts of NR2A, NR2B, NR2C corresponded to approximately 1:2:1. NR2D mRNA was also detectable. 5. In conclusion, mesencephalic neurones bear ethanol-sensitive NMDA receptors which might be involved in the development of ethanol dependence and withdrawal. The high affinity of NMDA to this receptor, its sensitivity to ifenprodil and memantine may suggest that the mesencephalic NMDA receptor comprises the NR1 splice variant lacking E5, NR2B, and NR2C, respectively.  (+info)

Antagonist activity of alpha-substituted 4-carboxyphenylglycine analogues at group I metabotropic glutamate receptors expressed in CHO cells. (7/5843)

1. We have investigated the antagonist properties of 6 alpha-substituted phenylglycine analogues based on the structure of 4-carboxyphenylglycine (4-CPG) for group I metabotropic glutamate receptors (mGlu1alpha and mGlu5a) permanently expressed in CHO cells. 2. (S)-4-CPG and (S)-MCPG were the most selective mGlu1alpha receptor antagonists. Longer chain alpha-carbon substitutions resulted in a progressive loss of antagonist affinity at mGlu1alpha receptors but not at mGlu5a receptors. Thus mGlu1alpha receptor antagonists require small aliphatic groups at the alpha-position. Alpha-cyclopropyl-4-CPG showed a tendency towards mGlu5a selectivity, suggesting that bulky groups at this position may favour mGlu5a receptor antagonism. 3. We demonstrate that the mGlu5a receptor displays agonist-dependent antagonism. L-glutamate-induced Ca2+ release in mGlu5a receptor expressing cells was more susceptible to antagonism by cyclic alpha-carbon derivatives than (S)-3,5-dihydroxyphenylglycine (DHPG)-induced Ca2+ release in the same cell line. 4. The data presented suggests that mGlu1alpha and mGlu5a receptors have different steric and/or conformational requirements for the binding of antagonists and different amino acids which could interact with agonists. 5. These phenylglycine analogues could provide leads for the development of subtype selective antagonists.  (+info)

Mechanisms involved in the metabotropic glutamate receptor-enhancement of NMDA-mediated motoneurone responses in frog spinal cord. (8/5843)

1. The metabotropic glutamate receptor (mGluR) agonist trans-(+/-)-1-amino-1,3-cyclopentanedicarboxylic acid (trans-ACPD) (10-100 microM) depolarized isolated frog spinal cord motoneurones, a process sensitive to kynurenate (1.0 mM) and tetrodotoxin (TTX) (0.783 microM). 2. In the presence of NMDA open channel blockers [Mg2+; (+)-5-methyl-10,11-dihydro-5H-dibenzo[a,d]cyclohepten-5,10-imine hydrogen maleate (MK801); 3,5-dimethyl-1-adamantanamine hydrochloride (memantine)] and TTX, trans-ACPD significantly potentiated NMDA-induced motoneurone depolarizations, but not alpha-amino-3-hydroxy-5-methylisoxazole-4-proprionate (AMPA)- or kainate-induced depolarizations. 3. NMDA potentiation was blocked by (RS)-alpha-methyl-4-carboxyphenylglycine (MCPG) (240 microM), but not by alpha-methyl-(2S,3S,4S)-alpha-(carboxycyclopropyl)-glycine (MCCG) (290 microM) or by alpha-methyl-(S)-2-amino-4-phosphonobutyrate (L-MAP4) (250 microM), and was mimicked by 3,5-dihydroxyphenylglycine (DHPG) (30 microM), but not by L(+)-2-amino-4-phosphonobutyrate (L-AP4) (100 microM). Therefore, trans-ACPD's facilitatory effects appear to involve group I mGluRs. 4. Potentiation was prevented by the G-protein decoupling agent pertussis toxin (3-6 ng ml(-1), 36 h preincubation). The protein kinase C inhibitors staurosporine (2.0 microM) and N-(2-aminoethyl)-5-isoquinolinesulphonamide HCI (H9) (77 microM) did not significantly reduce enhanced NMDA responses. Protein kinase C activation with phorbol-12-myristate 13-acetate (5.0 microM) had no effect. 5. Intracellular Ca2+ depletion with thapsigargin (0.1 microM) (which inhibits Ca2+/ATPase), 1,2-bis(O-aminophenoxy)ethane-N,N,N',N'-tetracetic acid acetyl methyl ester (BAPTA-AM) (50 microM) (which buffers elevations of [Ca2+]i), and bathing spinal cords in nominally Ca2+-free medium all reduced trans-ACPD's effects. 6. The calmodulin antagonists N-(6-aminohexyl)-5-chloro-1-naphthalenesulphonamide (W7) (100 microM) and chlorpromazine (100 microM) diminished the potentiation. 7. In summary, group I mGluRs selectively facilitate NMDA-depolarization of frog motoneurones via a G-protein, a rise in [Ca2+]i from the presumed generation of phosphoinositides, binding of Ca2+ to calmodulin, and lessening of the Mg2+-produced channel block of the NMDA receptor.  (+info)

Our study provided preliminary evidence that 4 weeks of supplementation with 3.0 g/day of guanidinoacetic acid is superior to creatine in facilitating cellular bioenergetics, as evaluated by the skeletal muscle and brain creatine levels, the researchers summarised.. But that doesnt mean that the researchers think athletes should start taking guanidinoacetic acid instead of their creatine supplements. The rise in homocysteine levels is too high for that in their view. It came perilously close to the 15 micromoles per litre that doctors regard as just still acceptable.. Guanidinoacetic acid loading should be considered as a controversial dietary routine since elevated homocysteine has been implicated as a risk factor for cardiovascular disease, renal dysfunction, and orosteoporotic fractures. Therefore, long-term safety studies evaluating different biomarkers of cardiometabolic health during guanidinoacetic acid loading are warranted before recommending it as a novel dietary supplement.. Some ...
The activity of the NMDA channel is controlled by the functional occupancy of both glutamate- and glycine-binding sites of the NMDAR (7). On the basis of our results, we conclude that under physiological conditions, the glycine site on the NMDAR is not saturated. Increasing the glycine concentration augments synaptically mediated NMDAR function in the hippocampal slices observed as an increase in PSC amplitude of more than 40%. Thus, regulation of the local glycine concentration at the synapse could be an important means to modulate the NMDAR component of glutamatergic transmission.. The results are consistent with a selective action of the NFPS to antagonize glycine transport proximal to the NMDAR. The enhancement of the evoked EPSC was blocked completely by APV, an antagonist of the NMDAR, and by 7-chlorokynurenate, an antagonist to the glycine-binding site on the NMDAR at which glycine acts as a coagonist. Although unlikely, it is possible that NFPS acts as a glycine agonist at this ...
The negative association between plasma glycine and LDL cholesterol in the current study was probably veiled by the intake of statins, since a greater proportion of patients in lower plasma glycine quartiles were prescribed statins. Accordingly, we observed a significant inverse trend between plasma glycine and LDL cholesterol after adjusting for statins, in line with the inverse association with apoB, but positive relationships with apoA‐1and high‐density lipoprotein cholesterol. This suggests an important role of glycine in lipid metabolism.. Indeed, considerable evidence suggests that glycine availability may be important in lipid metabolism and atherosclerosis. First, glycine can be methylated into sarcosine via GNMT, which is mainly confined to the liver and kidney29-30; however, rodent studies have shown that the GNMT is also localized to aortic endothelial cells.12 Impaired GNMT flux was shown to exacerbate lipid accumulation in both the liver and in macrophages, which can further ...
Glycine supplementation extends lifespan of male and female mice - posted in BioscienceNews: Abstract Diets low in methionine extend lifespan of rodents, though through unknown mechanisms. Glycine can mitigate methionine toxicity, and a small prior study has suggested that supplemental glycine could extend lifespan of Fischer 344 rats. We therefore evaluated the effects of an 8% glycine diet on lifespan and pathology of genetically heterogeneous mice in the context of the Interventions Te...
Guanidinoacetic acid (GAA) conversion to creatine is thought to be involved in cardiometabolic disturbances through its role in biological methylation and insulin secretion. We evaluated the association of serum GAA and creatine with cardiometabolic risk factors in a cohort of 151 apparently healthy adults (82 women and 69 men) aged 18-63 years. Serum levels of GAA and creatine were measured with liquid chromatography-tandem mass spectrometry. A multiple linear regression model adjusted for age and sex was employed to examine the relationship of serum GAA and creatine with cardiometabolic risk factors. Higher GAA levels were associated with an unfavorable cardiometabolic risk profile (higher insulin, higher total homocysteine, and higher body fat percentage), while having elevated serum creatine levels (≥31.1 µmol/L) was associated with being overweight (body mass index ≥ 25.0 kg/m). The results from our study suggest a possible role of the GAA-creatine axis in the pathogenesis of cardiovascular

Previous research has shown that a range of nitrosated glycine derivatives react with DNA to form O6-carboxymethylguanine and O6-methylguanine DNA adducts [Harrison et al. (1999) Chem. Res. Toxicol. 12, 106-111). Nitrosated glycine derivatives may be formed in the gastrointestinal tract from the reaction of dietary glycine with nitrosating agents. The aim of this study was to further investigate the role of dietary glycine in the formation of O6-guanine adducts at physiologically relevant concentrations. In vitro studies were performed by reacting 10 M to 50 mM glycine with nitric oxide in the presence of oxygen. An HPLC assay was developed to measure the resulting nitrosated glycine derivative, diazoacetate anion. The amount of nitrosating agent present in the reaction mixture was determined by colorimetric measurement of nitrite, the hydrolysis product of N2O3. Diazoacetate anion formation depended linearly on glycine concentration. Solutions of nitrosated glycine reacted with ...
Glycine is anti-inflammatory. Inflammation degrades organs, arteries, and joints. It attacks our hearts, blood vessels and when unchecked becomes chronic. It is not just a symptom it is also the disease. Glycine, taken as an oral supplement supports the bodies fight to reduce inflammation.. Glycine also helps to regulate sugar levels in blood and moves blood sugar to tissues and cells for consumption as energy. Low glycine levels are associated with a higher risk of developing type 2 diabetes. Contrarily, higher levels of glycine are linked to a lower risk of this metabolic disorder.. Glycine supports healthy PH levels in the digestive tract where it supports the breakdown of fatty acids.. Glycine is a component of creatine synthesis.

Mitochondria were isolated from light grown and dark grown monocotyledonous (wheat-Triticum aestivum and barley-Hordeum vulgare) and dicotyledonous (pea-Pisum sativum) plants and their capacity to oxidize glycine was measured. In all of the studied plant species the rate of mitochondrial glycine oxidation was high in light grown leaves. Glycine oxidation in mitochondria from etiolated leaves was also very substantial; the rate of glycine oxidation relative to the oxidation of other substrates was about half as compared to green tissue. In etiolated non-photosynthetic tissues the relative glycine oxidation was only ca 20% of that measured in green leaves. The effect of light on the development of glycine oxidation capacity was studied using etiolated barley which was transferred to light for 6 to 24 h. During this time the rate of glycine oxidation as compared to the oxidation of NADH and malate increased, approaching the ratio observed in light grown leaves. It is concluded that the synthesis of ...

1. The tumour cells were starved in a solution lacking Na+ and then transferred to a Ringer solution containing 2mm-sodium cyanide, 150m-equiv. of Na+/l. and 10m-equiv. of K+/l. Such cells were depleted of ATP and contained an endogenous pool of various amino acids equivalent to a 26mm solution. 2. At 4min. after the transfer the cellular Na+ content had increased by about 100% and roughly an equivalent amount of K+ had left the cells. 3. Under these conditions [14C]glycine was absorbed from an 11mm solution and reached the same cellular concentration by about 4min. The pool size increased by approximately the same amount (ΔGly), so glycine did not simply exchange with the endogenous components. 4. After 4min. with glycine, the cells contained about 20% more Na+ (ΔNa+) than the control and about 10% less K+ (ΔK+). The mean values of ΔNa+/ΔGly and ΔK+/ΔGly from five experiments were respectively 0·90±0·11 and 0·62±0·11equiv./mole. 5. A further indication that these two ratios were ...

After bringing together a list of supplements to buy for my next stack, I came across Glycine. A mostly un-talked about amino acid which got me thinking about its role and how I would benefit from it. I think the research speaks for itself, and Glycine will be now first in my basket when doing my monthly supplement shop!Glycine is the simplest amino acid found in the body. It is a non essential amino acid and is found in many dietary foods especially those high in protein such as meat, fish, milk and eggs.The main function of Glycine is to act as the precursor to proteins. It is the smallest of the protein building aminos and is the building block of many natural products including that of muscle and other tissues within the body.So if its so abundant and non essential through diet why supplement it?Well it has been shown to increase the absorption of key nutrients.By combining carbohydrates and glycine there has been shown to be a greater use of glucose for energy before, during and after exercise
Here are 5 ways to help maintain healthy collagen levels as you age:. #1 Bone Broth. Bone Broth has been used as a healing concoction in traditional cultures for centuries. Bone broth is made from nothing more than water, animal bones, vegetables, and seasoning. Often the bones are roasted first, before simmering for very long periods of time, usually more than 24 hours - so that not only gelatin (which is a hydrolyzed form of collagen), but also many healthful minerals, are released into the broth.xxiii. Bone broth is very rich in the amino acids glycine and proline. Glycine supports detoxification, while proline supports skin health, especially in combination with vitamin C. Gelatin also supports skin health and tone.xxiv. Bone broth also contains glucosamine and chondroitin sulfate, which combine to support healthy cartilage. Additionally, bone broth contains hyaluronic acid (also found in beans and root vegetables) which is given on its own as a supplement to osteoarthritis patients and is ...

rs283413, also known as c.232G,T, p.Gly78Ter, G78stop and Gly78X, encodes a rare variant of the ADH1C gene that leads to a truncated alcohol dehydrogenase protein. These types of proteins are involved in detoxification and may be linked to neurodegenerative diseases. The rs283413(G) allele is the more common, encoding the amino acid glycine (Gly); the quite rare rs283413(T) allele encodes the variant stop codon (X). Originally identified in three Swedish patients with Parkinsons disease (PD), a study of ~1000 PD patients vs. ~1000 controls indicated an odds ratio for the risk allele of 3.25 (CI:1.31-8.05). [This risk is effectively for heterozygotes, since the risk allele is so rare that no homozygotes for it were observed.] In a study of 40 index cases, 10% were found to harbor the rs283413(T) risk allele. [PMID 15642852] On its own, this SNP is also said to explain 9.0% of the variability in the rate at which alcohol is metabolized, based on a study of 250 Spaniards.[PMID 20101753] More ...
Collagen is a protein made up of amino-acids, which are in turn built of carbon, oxygen and hydrogen. Collagen contains specific amino acids - Glycine, Proline, Hydroxyproline and Arginine.
Spark-tube experiments and analysis of meteorite contents have led to the widespread notion that abiotic organic molecules were the first life components. However, there is a contradiction between the abundance of simple molecules, such as the amino acids glycine and alanine, observed in these studies, and the minimal functional complexity that even the least sophisticated living system should require. I will argue that although simple abiotic molecules must have primed proto-metabolic pathways, only Darwinian evolving systems could have generated life. This condition may have been initially fulfilled by both replicating RNAs and autocatalytic reaction chains, such as the reductive citric acid cycle. The interactions between nucleotides and biotic amino acids, which conferred new functionalities to the former, also resulted in the progressive stereochemical recognition of the latter by cognate anticodons. At this point only large enough amino acids would be recognized by the primordial RNA adaptors and

Since its founding by Eugène Meylan in 1914, Glycine has been producing watches at its factory in Bienne, Switzerland. Glycine became a noteworthy watch maker in the early 1950s for the introduction of their Airman model, a 24 hour watch favored by both military and commercial pilots. The Airman was worn by many United States Air Force pilots during the Vietnam War. Glycine still makes several variants of the Airman. Other models in the Glycine line include the Incursore, Combat, and Lagunare series. ...
The present data illustrate that the tricyclic pyrido-phthalazine-dione derivatives studied are moderately potent and selective glycineB antagonists in vitro. Most compounds displaced [3H]DCKA, [3H]MDL-105,519 and [3H]glycine binding to rat cortical membranes with high nanomolar affinity and antagonized steady-state inward current responses of cultured hippocampal neurons to NMDA with high nanomolar to low micromolar affinity. The NMDA receptor antagonism observed was typical for glycineB antagonists,i.e., showed competition with glycine, revealed glycine-dependent desensitization (Mayer et al., 1989a,b;Lerma et al., 1990, Vyklicky et al., 1990;Parsons et al., 1993) and was not use- or voltage-dependent. Much higher concentrations were required to antagonize steady-state inward current responses to AMPA and, in this case, the antagonism observed was reminiscent of a competitive interaction (Parsons et al., 1994). These effects on AMPA receptors agree closely with provisional unpublished data ...

When and how often laboratory tests are done may depend on many factors. The timing of laboratory tests may rely on the results or completion of other tests, procedures, or treatments. Lab tests may be performed immediately in an emergency, or tests may be delayed as a condition is treated or monitored. A test may be suggested or become necessary when certain signs or symptoms appear. Due to changes in the way your body naturally functions through the course of a day, lab tests may need to be performed at a certain time of day. If you have prepared for a test by changing your food or fluid intake, lab tests may be timed in accordance with those changes. Timing of tests may be based on increased and decreased levels of medications, drugs or other substances in the body. The age or gender of the person being tested may affect when and how often a lab test is required. Chronic or progressive conditions may need ongoing monitoring through the use of lab tests. Conditions that worsen and improve may ...

To study the distribution of glycine immunoreactive neurons in the spinal cord and brain, antisera were raised against glycine conjugated to protein carriers. High-titer rabbit glycine antiserum was purified by affinity chromatography. Testing against other amino acids and peptides with immuno dot blots and ELISA assays showed little apparent cross-reaction with glutamate, aspartate, glutamine, taurine, and 17 other amino acids and related compounds. Similarly, the antiserum showed little apparent recognition of glycine when glycine was incorporated into peptides. A slight cross-reactivity with GABA, beta- alanine, and cysteine was found. Immunocytochemical labeling of tissue sections could be blocked with glycine conjugated to a heterologous carrier protein but not by other amino acids conjugated to that protein. Immunocytochemistry at the light microscope level with immunofluorescence and silver-intensified colloidal gold revealed a wide distribution of glycine-like immunoreactivity throughout ...

TY - JOUR. T1 - Inhibitory effect of ondansetron on glycine response of dissociated rat hippocampal neurons. AU - Ye, Jiang Hong. AU - Schaefer, Rebecca. AU - Wu, Wen Hsien. AU - Liu, Philip L.. AU - Zbuzek, Vlasta K.. AU - McArdle, Joseph J.. PY - 1999/7/1. Y1 - 1999/7/1. N2 - We examined the effect of ondansetron, an antagonist of type 3 serotonin receptors, on the whole cell response of freshly isolated hippocampal CA1 pyramidal neurons of neonatal and mature rats to glycine using the gramicidin perforated patch technique. Ondansetron depressed the current induced by subsaturating concentrations of glycine (I(Gly)) in a concentration-dependent manner. The ondansetron concentration needed to depress I(Gly) induced by 30 μM glycine to half amplitude was 25 μM. Ondansetron (54 μM) shifted the glycine concentration-response curve to the right in a parallel manner, increasing the EC50 for glycine from 40 ± 3 μM to 70 ± 5 μM. Ondansetron increased the time constant of activation of I(Gly) ...
Multiple rare structural variants of relatively recent evolutionary origin are recognized as important risk factors for schizophrenia (SZ) and other neurodevelopmental disorders (e.g., autism spectrum disorders, mental retardation, epilepsy) with odds ratios as high as 7-30 (Sebat et al. 2009; Malhotra et al. 2011; Heinzen et al. 2010; Weiss et al. 2008; McCarthy et al. 2009). We have found a de novo structural rearrangement on chromosome 9p24.1 in two psychotic patients. One of the genes in this region is the gene encoding glycine decarboxylase (GLDC), which affects brain glycine metabolism. GLDC encodes the glycine decarboxylase or glycine cleavage system P-protein, which is involved in degradation of glycine in glia cells. Carriers of the GLDC triplication would be expected to have low levels of brain Gly, resulting in NMDA receptor-mediated hypofunction, which has been strongly implicated in the pathophysiology of schizophrenia (Olney & Farber, 1995; Coyle, 2006; Javitt, 2007).. There is an ...
Glycine is an important inhibitory transmitter in the brainstem and spinal cord. Glycine receptors are members of the ligand-gated ion channel family (LGICs) that mediate rapid chemical neurotransmission (Schofield et al., 2003). The binding of glycine to its receptor produces a large increase in chloride conductance, which causes membrane hyperpolarization. Glycine receptors are anchored at inhibitory chemical synapses by a cytoplasmic protein, gephyrin (Fischer et al., 2000). The glycine receptor has been used to great advantage in the identification of the binding sites for alcohol on the LGIC family of proteins (Beckstead et al., 2001; Mihic et al., 1997). These receptors have also been extremely useful in studies of synaptic clustering of receptors (Craig and Lichtman, 2001). The glycine receptor may also act in concert with an NMDAR subunit to form an excitatory receptor (Chatterton et al., 2002).. ...
Glycine receptors (GlyRs) are inhibitory ligand-gated ion channels. Ethanol potentiates glycine activation of the GlyR, and putative binding sites for alcohol are located in the transmembrane (TM) domains between and within subunits. To alter alcohol sensitivity of GlyR, we introduced two mutations in the GlyR α1 subunit, M287L (TM3) and Q266I (TM2). After expression in Xenopus laevis oocytes, both mutants showed a reduction in glycine sensitivity and glycine-induced maximal currents. Activation by taurine, another endogenous agonist, was almost abolished in the M287L GlyR. The ethanol potentiation of glycine currents was reduced in the M287L GlyR and eliminated in Q266I. Physiological levels of zinc (100 nM) potentiate glycine responses in wild-type GlyR and also enhance the ethanol potentiation of glycine responses. Although zinc potentiation of glycine responses was unchanged in both mutants, zinc enhancement of ethanol potentiation of glycine responses was absent in M287L GlyRs. The Q266I ...
We have found that glycine uptake inhibitors that enhance NMDA glutamate receptor activity promote striatal dopaminergic re-innervation in a toxin-based pre-clinical model of Parkinsons disease. Adult mice received unilateral intrastriatal 6-OHDA injections. Three weeks after the lesion the dorsal striatum was devoid of dopamine neurites. After an additional four weeks, a gradual and partial dopaminergic re-innervation of the dorsal striatum occurred in untreated mice. This re-innervation was enhanced by 30% when mice were treated with a glycine uptake inhibitor beginning three weeks after the lesion. Dopamine release recordings indicated that this recovery was also functional. Thus, glycine uptake inhibitors promote functional dopaminergic sprouting, a finding that we think should be carefully examined as a new avenue for therapy development for Parkinsons disease ...
Scientists have determined the structure of Glycine Transporter 1. The finding could open new avenues for developing therapeutics for psychiatric disorders.. Glycine regulates neuronal activity in the brain. Glycine is the smallest amino acid - one of the building blocks of proteins. It acts also as a neurotransmitter in the brain, enabling neurons to communicate with each other and modulating neuronal activity. Many researchers have focused on increasing glycine levels in synapses to find an effective treatment for schizophrenia. This could be done using inhibitors targeting Glycine Transporter 1 (GlyT1), a protein that sits in neuronal cell membranes and is responsible for the uptake of glycine into neurons. However, the development of such drugs has been hampered because the 3D structure of GlyT1 was not known.. To determine the structure of GlyT1, researchers at the Danish Research Institute of Translational Neuroscience (DANDRITE), which is part of the Nordic EMBL Partnership for Molecular ...

Glycine receptors are ligand-gated chloride channels (PubMed:23994010, PubMed:25730860). Channel opening is triggered by extracellular glycine (PubMed:2155780, PubMed:7920629, PubMed:14551753, PubMed:16144831, PubMed:22715885, PubMed:22973015, PubMed:25973519, PubMed:9009272). Channel opening is also triggered by taurine and beta-alanine (PubMed:16144831, PubMed:9009272). Channel characteristics depend on the subunit composition; heteropentameric channels are activated by lower glycine levels and display faster desensitization (PubMed:14551753). Plays an important role in the down-regulation of neuronal excitability (PubMed:8298642, PubMed:9009272). Contributes to the generation of inhibitory postsynaptic currents (PubMed:25445488). Channel activity is potentiated by ethanol (PubMed:25973519). Potentiation of channel activity by intoxicating levels ot ethanol contribute to the sedative effects of ethanol (By similarity ...
The glycine receptor of rat spinal cord is an oligomeric membrane glycoprotein of molecular mass 250,000 daltons that contains three polypeptides of 48,000, 58,000, and 93,000 daltons. Monoclonal antibodies (mAbs) were prepared against the affinity-purified glycine receptor protein by using 125I-labeled receptor preparations for the detection of positive hybrids. From nine monoclonal antibodies obtained, six recognized denatured receptor polypeptides blotted to nitrocellulose paper. Two of these antibodies bound to more than one glycine receptor polypeptide: mAb GlyR 4a stained the 48,000- and 58,000-dalton polypeptides, and mAb GlyR 7a stained the 48,000- and 93,000-dalton polypeptides. Common antigenic determinants thus are shared by the different subunits of the glycine receptor. Complementary results were obtained by peptide mapping of 125I-labeled glycine receptor polypeptides with various proteases. A set of peptide fragments of the same apparent molecular mass was produced from the ...

In keeping with our vehicle example, look at this website if GABA is the brake on the nerve in neuropathy and Glutamate imitate the gas pedal, a 3rd chemical known as Glycine may be thought of as the transmission. Glycine slows the worried system down. Think about shifting the nerve into low gear. Glycine down shifts the nerve in neuropathy straight thus decreasing and inhibiting uncomfortable transmission of nerve signals, but likewise it likewise may indirectly contend with Glutamate. The system by which Glycine might offer relief to clients suffering from neuropathy is a little less direct. The nerves would slow down if a client would take a big dose of Glycine. This impact would not last long nevertheless, due to the fact that in the nerve system Glycine is brought away from the nerve by exactly what is called a Glycine Transporter. The Glycine Transporter has the net impact of eliminating Glycine which effectively shifts the nerve system back into high equipment. This Glycine Transporter ...

When rat dams consume a diet low in protein during pregnancy, their offspring develop high blood pressure. On a low-protein diet, the endogenous formation of the amino acid glycine is thought to become constrained. Glycine may become conditionally essential, as its rate of endogenous formation is inadequate to meet metabolic needs, and may be limiting for the normal development of the fetus. In the present study, five groups of Wistar rats were provided during pregnancy with one of five diets: a control diet containing 18% (w/w) casein (CON), a low-protein diet containing 9% casein (MLP), or the low-protein diet supplemented with 3% glycine (MLPG), alanine (MLPA) or urea (MLPU). The offspring were weaned on to standard laboratory chow, and blood pressure was measured at 4 weeks of age. Blood pressure was significantly increased in the MLP, MLPA and MLPU groups compared with the CON group, but for the MLPG group blood pressure was not significantly different from CON. Compared with the CON group, ...
The occurrence of quasi-repetitive glycine-rich peptides has been reported in different organisms. Glycine-rich regions are proposed to be involved in protein-protein interactions in some mammalian protein families. In plants, a set of glycine-rich proteins (GRPs) was characterized several years ago, and since then a wealth of new GRPs have been identified. GRPs may have very diverse sub-cellular localization and functions. The only common feature among all different GRPs is the presence of glycine-rich repeat domains. The expression of genes encoding GRPs is developmentally regulated, and also induced, in several plant genera, by physical, chemical and biological factors. In addition to the highly modulated expression, several GRPs also show tissue-specific localization. GRPs specifically expressed in xylem, phloem, epidermis, anther tapetum and roots have been described. In this paper, the structural and functional features of these proteins in Eucalyptus are summarized. Since this is the ...
Glycine is a simple amino acid. The glycine cleavage enzyme system comprises four proteins: P-, T-, H- and L-proteins (EC, EC and EC for P-, T- and L-proteins). The glycine cleavage system catalyses the oxidative conversion of glycine into carbon dioxide and ammonia, with the remaining one-carbon unit transferred to folate as methylenetetrahydrofolate. It is the main catabolic pathway for glycine and it also contributes to one-carbon metabolism ...
In the present study, we demonstrate a robust activation of extrasynaptic GlyRs in CA3 pyramidal neurons of the neonatal hippocampus caused by endogenous, nonsynaptically released glycine. The conclusion that glycine acts as a major endogenous agonist of GlyRs gains strong support from the finding that the frequency of GlyR openings was facilitated by blocking glycine uptake via GlyT1. Furthermore, we show that the release of glycine is not dependent on extracellular Ca2+ ions, neuronal activity, or reverse operation of GlyT1. At a physiological concentration of extracellular glycine, the nonsynaptic activation of GlyRs has an inhibitory action in the neonatal hippocampus.. Pharmacological inhibition of GlyT1 led to a dramatic increase in the effect of exogenous glycine, which implies a very high efficacy of uptake by the transporter. The increase in nonsynaptic GlyR current caused by the transport blocker NFPS indicates that GlyT1 operates in a net uptake mode in neonatal hippocampal slices ...
The researchers found no statistically significant effects on the total outcome of the SMH Sleep Questionnaire. The questionnaire contained the question How clear-headed did you feel after getting up this morning? and the answers to this question were statistically significant. After a night of sleep enhanced by glycine the subjects felt more clear-headed than after a normal nights sleep.. Glycine has been ingested as a component of foodstuff for a long time, and the safety of glycine is considered higher than that of sleeping drugs, the Japanese write. No serious side-effects were noted when up to 30 g/day of glycine was given in humans.. These results suggest that the safety of glycine is relatively high and that oral glycine administration produces good subjective feeling after awakening from sleep in humans who are dissatisfied with their sleep quality.. ...

At least 25 mutations in the CLN8 gene have been found to cause CLN8 disease. CLN8 disease is an inherited disorder that varies in severity and primarily affects the nervous system. The less-severe form of CLN8 disease is characterized by recurrent seizures (epilepsy) and a decline in intellectual function that begins between ages 5 and 10. Individuals with the less-severe form of CLN8 disease often live into late adulthood. People with the more-severe form of CLN8 disease experience a gradual worsening of motor and cognitive skills, epilepsy, and vision loss. In this form, signs and symptoms typically appear between ages 2 and 7. Individuals with the more-severe form of CLN8 disease usually survive only into late childhood or adolescence.. A specific mutation that replaces the protein building block (amino acid) arginine with the amino acid glycine at position 26 in the CLN8 protein (written as Arg26Gly or R26G) is found in all individuals from a northern region of Finland who have the ...
The endogenous polyamine spermine has multiple effects on the N-methyl-D-aspartate (NMDA) receptor. These include an increase in the magnitude of NMDA-induced whole-cell currents that is seen in the presence of saturating concentrations of glycine (glycine-independent stimulation), an increase in the affinity of the receptor for glycine (glycine-dependent stimulation), and voltage-dependent inhibition. Although many of the properties of native NMDA receptors are seen with homomeric NR1 receptors expressed in Xenopus oocytes, we have found that the effects of spermine are differentially regulated by NR2 subunits in heteromeric NR1/NR2 receptors. Glycine-independent stimulation by spermine occurred at homomeric NR1A receptors, which lack the amino-terminal insert in NR1, and at heteromeric NR1A/NR2B receptors but not at heteromeric NR1A/NR2A or NR1A/NR2C receptors. Glycine-independent stimulation was not seen at homomeric NR1B receptors, which include the amino-terminal insert in NR1, or at ...
Poly (A)+ messenger RNA (mRNA) was extracted from rat and chick brains, and injected into oocytes of Xenopus laevis. This led to the expression of receptors that evoked membrane currents in response to γ-aminobutyric acid (GABA), glycine and β-alanine. These currents all inverted at about the chloride equilibrium potential in the oocyte, and showed a marked rectification at negative potentials. Oocytes injected with mRNA from chick optic lobe gave large responses to GABA and β-alanine, but small responses to glycine. In contrast, one fraction of mRNA from rat cerebral cortex (obtained by sucrose density gradient centrifugation) caused oocytes to develop sensitivity to GABA, glycine and β-alanine, whereas a different fraction induced sensitivity to glycine and β-alanine, but very little to GABA. The pharmacological properties of the three amino acid responses also differed. Barbiturate and benzodiazepines potentiated the responses to GABA and β-alanine, but not to glycine. Strychnine ...

Glutathione is a tripeptide constructed from three amino acids - Glycine, Glutamic Acid, and Cysteine. Your body produces its own Glutathione using these amino acids. What we know is that poor diet, digestion, and protein metabolism along with pollution, heavy metals, toxins, viruses, bacteria, medications, stress, trauma, aging, infections, radiation, and even the normal aging process can all deplete your Glutathione. The main function of glutathione is to protect the cell and mitochondria from oxidative and peroxidative damage. Meaning glutathione isnt just an endogenous antioxidant; it is also an essential factor in energy utilization. Indeed, mitochondrial dysfunction, muscle weakness, fatigue and aging are linked to glutathione deficiency. And low glutathione levels are linked to energy deficiency (low ATP). Evidently, the main mechanism that triggers glutathione synthesis in the body is cellular energy. High cellular levels of energy molecules (ATPs) promote glutathione synthesis. This is ...
Somatic ribosomal protein mutations have recently been described in cancer, yet their impact on cellular transcription and translation remains poorly understood. Here, we integrate mRNA sequencing, ribosome footprinting, polysomal RNA sequencing and mass spectrometry datasets from a mouse lymphoid cell model to characterize the T-cell acute lymphoblastic leukemia (T-ALL) associated ribosomal RPL10 R98S mutation. Surprisingly, RPL10 R98S induces changes in protein levels primarily through transcriptional rather than translation efficiency changes. Phosphoserine phosphatase (PSPH), encoding a key serine biosynthesis enzyme, was the only gene with elevated transcription and translation leading to protein overexpression. PSPH upregulation is a general phenomenon in T-ALL patient samples, associated with elevated serine and glycine levels in xenograft mice. Reduction of PSPH expression suppresses proliferation of T-ALL cell lines and their capacity to expand in mice. We identify ribosomal mutation ...
Amino acids, such as valine, isoleucine and leucine compete with tyrosine and tryptophan for transport into the brain and might thus affect the central serotonin and catecholamine patterns. Furthermore, the excitatory amino acids glutamic acid, aspartic acid and glycine are known to act on the N-methyl-D-aspartate receptor, which is part of the reward system. Based on these facts, we have explored the role of cerebrospinal fluid (CSF) amino acids in pathological gambling. Concentrations of amino acids were determined in CSF obtained from one female and 11 pathological male gamblers and 11 healthy male controls. In an ANCOVA with best subset regression, pathological male gamblers had higher CSF levels of the excitatory glutamic and aspartic acids, as well as of phenylalanine, isoleucine, citrulline and glycine. A negative contribution of glycine in interaction with the neuraxis distance might mirror a reduced spinal supply or an altered elimination of glycine in pathological gamblers. A ...
Animation IM13.3. A backbone drawing of bovine low molecular weight protein tyrosyl phosphate with bound inorganic phosphate.. The order in which a chain of amino acids is connected together is called the primary structure of a protein. For example, the amino acids glycine, alanine, tyrosone and arginine could be connected in the order gly-ala-tyr-arg, or ala-gly-arg-tyr, or tyr-gly-ala-arg, and so on. These compounds are isomers of each other. Knowing which isomer we have tells us something about the protein.. The way that chain arranges itself is called the secondary structure. Very often, proteins coil up into spirals or helices. This helical structure is similar to that of DNA. Another possible secondary structure is a beta-sheet, which is sort of wavy, a bit like a sheet of corrugated steel. These secondary structures are held in place by hydrogen bonds between different amino acids. (You can see the structure-property relationship chapter to review hydrogen bonding).. Usually, the entire ...
We have been engaged in the microwave-solid phase peptide synthesis (SPPS) synthesis of the phenylglycine (Phg)-containing pentapeptide H-Ala-Val-Pro-Phg-Tyr-NH2 (1) previously demonstrated to bind to the so-called BIR3 domain of the anti-apoptotic protein XIAP. Analysis of the target peptide by a combination of RP-HPLC, ESI-MS, and NMR revealed the presence of two diastereoisomers arising out of the racemisation of the Phg residue, with the percentage of the LLLDL component assessed as 49%. We performed the synthesis of peptide (1) using different microwave and conventional stepwise SPPS conditions in attempts to reduce the level of racemisation of the Phg residue and to determine at which part of the synthetic cycle the epimerization had occurred. We determined that racemisation occurred mainly during the Fmoc-group removal and, to a much lesser extent, during activation/coupling of the Fmoc-Phg-OH residue. We were able to obtain the desired peptide with a 71% diastereomeric purity (29% LLLDL ...
ABSTRACT: To test the hypothesis that dissolved organic nitrogen (DON) is important for sustaining primary production by the microphytobenthos (MPB) in nitrogen-limited conditions, we measured the uptake of 15N-labelled urea, the amino acids glycine (GLY) and glutamic acid (GLU), and nitrate and ammonium under simulated in situ light and temperature conditions. Microphytobenthic primary production and chlorophyll a (chl a) were also measured. The MPB was dominated by diatoms attached to sand grains, with cyanobacteria making up ~30% of the biomass. Activities of the hydrolytic ectoenzymes leucine aminopeptidase (AMA), alkaline phosphatase (APA) and β-glucosidase (GLA) in filter-fractionated sediment showed that the microbenthic community was strongly deficient in nitrogen (N), with the bacterial fraction (,1 µm) also limited in phosphorus. Uptake of DON (urea + GLU + GLY) accounted for ~50 to 65% of the uptake of 15N-labelled substrates, with a higher proportion of DON uptake at low substrate ...
What does alanine do?. Alanine is a nonessential amino acid used by the body to build proteins.. Alanine is present in prostate fluid, and it may play a role in supporting prostate health. One study, involving 45 men with benign prostatic hyperplasia (BPH), found that 780 mg of alanine per day for two weeks and then 390 mg for the next two and a half months, taken in combination with equal amounts of the amino acids glycine and glutamic acid, reduced symptoms of BPH;1 this work has been independently confirmed.2 ...

For many years it was thought that chromium was included as part of a substance called GTF (Glucose Tolerance Factor). GTF were along with chromium believed to consist of the B vitamin, niacin, and the amino acids glycine, cysteine and glutamic acid. The theory of GTF was only partially supported, and the existence of a specific GTF molecule in the body has never been proven.. More recent research has however revealed the existence of a unique chrome-binding molecule called chromodulin, which is slightly different from GTF, but with the same characteristics. So when we talk about chromodulin instead of GTF, its the same benefits we are referring to.. The bodys chromium reserve is around 4-6 mg. With increasing age, the concentration of chromium in various tissues may drop significantly. Snacking on something sweet may offer temporary relief because of the quick sugar fix that gives immediate energy, but the effect wears off soon after, leaving them where they started.

b)The destruction of invading bacteria or other microbes in response to infection, via secretion TNFα and a host of cascading toxins, i.e., inflammation. These two types of macrophage activity are initiated by distinct signaling pathways (6). Activation of inflammation where infection is not present only produces damage to normal tissues. This dual functionality of macrophages may be likened to the action of first responders such as the police. The police are called to the scene of an accident on the highway, and do what is necessary to clear the area of damaged vehicles and persons, to restore the normal flow of traffic. But whilst they are armed (e.g., in the US), they do not draw nor fire their weapons unless bad actors are present. The drawing and use of firearms may be likened to inflammation in the body.. 3)Physiologically, the priming or activation of macrophages of all types, to produce inflammation, is naturally regulated by the amino acid glycine (8). This has now been confirmed ...
Because the glycine brace is the single structural feature that most distinguishes Rab-related GTPases from other Ras-like GTPases (Figure 2B), it presumably plays a critical functional role somehow related to the conserved atomic interactions described above. Given that the guanine-binding loop and the P-loop bind to both ends of GTP or GDP, the glycine brace could promote guanine nucleotide binding by stabilizing the conformations of these glycines, which could serve as hinges for opening and closing of these loops. Conversely, disruption of these aromatic-glycine interactions could promote the release of GDP during nucleotide exchange. It is worthwhile noting in this context that the most buried residue (164 Ǻ2) of Ran GTPase upon binding to its nucleotide exchange factor, RCC1 [20], is a lysine that is located near the center of the glycine brace α helix (Lys99-Ran in Figure 3D). Moreover, in the Ran-RCC1 crystal structure this lysine is inserted into the central hole of RCC1s ...

As a neurotransmitter, glycine affects the functioning of the nervous system, so it is responsible for suppressing the signs of depression, is beneficial for concentration and memory, and is used at bedtime to improve its quality and facilitate the building and regeneration of muscles. In addition, it participates in the synthesis of erythrocytes, haemoglobin and nucleic acid components, is present in the bodys detoxifying processes, participates in glucose and creatine biosynthesis and acts anti-sour and anti-inflammatory.. Glycine is a substance that does not occur on its own. It is, however, a component of numerous supplements - often found in testosterone boosters, creatine stacks, amino acid or carbohydrate protein. According to research, glycine sales last year increased fivefold. It is assumed that supplementation should be 1-3 g of product containing it in its composition. Glycine is also found in natural foods, both in animal and vegetable products, so varied diets. It will also be a ...

N-Arachidonyl glycine receptor (NAGly receptor), also known as G protein-coupled receptor 18 (GPR18), is a protein that in humans is encoded by the GPR18 gene. Along with the other previously orphan receptors GPR55 and GPR119, GPR18 has been found to be a receptor for endogenous lipid neurotransmitters, several of which also bind to cannabinoid receptors. Research supports the hypothesis that GPR18 is the abnormal cannabidiol receptor and N-arachidonoyl glycine, the endogenous lipid metabolite of anandamide, initiates directed microglial migration in the CNS through activation of GPR18, though recent evidence demonstrates that NAGly was not shown to be a GPR18 agonist in rat sympathetic neurons. Resolvin D2 (RvD2), a member of the specialized proresolving mediators (SPM) class of polyunsaturated fatty acid metabolites, is an activating ligand for GPR18; RvD2 and its activation of GPR18 contribute to the resolution of inflammatory responses as well as inflammation-based and other diseases in ...
A high concentration of PTH can promote the transformation of preosteoclasts and stromal cells into osteoclasts. Highly active osteoclasts dissolve bone minerals by secreting acid onto the isolated surface, and simultaneously break down the bone matrix by secreting collagenase and hydrolase. Increased levels of glycylproline, the end product of collagen metabolism, were found when bone collagen was disrupted. Glycylproline can be further digested by prolidase to glycine and proline, and we found decreased glycylproline and increased glycine levels in urine collected from the LCG rats. Glycine is involved in the synthesis of collagen. Phenylacetylglycine is a glycine conjugate of phenylacetic acid. Decreased glycylproline and increased glycine and phenylacetylglycine levels in urine suggested disruption of bone collagen. The results of our study suggest that glycylproline, glycine, and phenylacetylglycine could be involved in the metabolic pathway of the degradation and biosynthesis of bone ...

Patients with severe forms of COVID-19 often develop acute respiratory distress syndrome (ARDS) associated with high levels of proinflammatory cytokines and damage of lungs and other organs. A special feature in these patients is thrombotic events in the micro- and macro-vasculature. Owing to the lack of a specific and efficient treatment against COVID-19, lowering of this cytokine storm is a further proposed strategy.. Glycine is the major agonist of glycine receptors (GlyR), which are chloride channels that hyperpolarize cell membranes of inflammatory cells such as macrophages and neutrophils, turning them less sensitive to proinflammatory stimuli. In addition, glycine possesses a cytoprotective effect, improves endothelial function, and diminishes platelet aggregation.. In laboratory animals, in a rat model of endotoxic shock a 5% glycine-rich diet lowers mortality, reduces pulmonary neutrophilic inflammation and hepatic lesions, and avoids elevation of serum TNF-alpha. In animal models of ...

Juvenile chickens of less than 28 days of age at slaughter in the United Kingdom are marketed as poussin. Mature chicken is sold as small, medium or large. Whole mature chickens are marketed in the United States as fryers, broilers, and roasters. Fryers are the smallest size (2.5-4 lbs dressed for sale), and the most common, as chicken reach this size quickly (about 7 weeks). Most dismembered packaged chicken would be sold whole as fryers. Broilers are larger than fryers. They are typically sold whole. Roasters, or roasting hens, are the largest chickens commonly sold (3-5 months and 6-8 lbs) and are typically more expensive. Even larger and older chickens are called stewing chickens but these are no longer usually found commercially. The names reflect the most appropriate cooking method for the surface area to volume ratio. As the size increases, the volume (which determines how much heat must enter the bird for it to be cooked) increases faster than the surface area (which determines how fast ...
... wood is very hard, stiff, dense and shock resistant. There are woods that are stronger than hickory and woods that are harder, but the combination of strength, toughness, hardness, and stiffness found in hickory wood is not found in any other commercial wood.[5] It is used for tool handles, bows, wheel spokes, carts, drumsticks, lacrosse stick handles, golf club shafts (sometimes still called hickory stick, even though made of steel or graphite), the bottom of skis, walking sticks, and for punitive use as a switch (like hazel), and especially as a cane-like hickory stick in schools and use by parents. Paddles are often made from hickory. This property of hickory wood has left a trace in some Native American languages: in Ojibwe, hickory is called mitigwaabaak, a compound of mitigwaab "bow" and the final -aakw "hardwood tree".[6] Baseball bats were formerly made of hickory, but are now more commonly made of ash. Hickory is replacing ash as the wood of choice for Scottish shinty sticks ...
The almond is highly revered in some cultures. The tree originated in the Middle East,[70] and is mentioned numerous times in the Bible. In the Hebrew Bible, the almond was a symbol of watchfulness and promise due to its early flowering. In the Bible the almond is mentioned ten times, beginning with Book of Genesis 43:11, where it is described as "among the best of fruits". In Numbers 17 Levi is chosen from the other tribes of Israel by Aaron's rod, which brought forth almond flowers. According to tradition, the rod of Aaron bore sweet almonds on one side and bitter on the other; if the Israelites followed the Lord, the sweet almonds would be ripe and edible, but if they were to forsake the path of the Lord, the bitter almonds would predominate. The almond blossom supplied a model for the menorah which stood in the Holy Temple, "Three cups, shaped like almond blossoms, were on one branch, with a knob and a flower; and three cups, shaped like almond blossoms, were on the other...on the ...
Although they are grown as ornamental trees in many areas of the Old World tropics of Indonesia, Malaysia and the Philippines, only the Philippines produces and processes pili nuts commercially. Production centers are located in the Bicol region, provinces of Sorsogon, Albay, and Camarines Sur, southern Tagalog, and eastern Visayas. There is no commercial planting of this crop; fruits are collected from natural stands in the mountains near these provinces. In 1977, the Philippines exported approximately 3.8 t of pili preparation to Guam and Australia. The most important product from pili is the kernel. When raw, its flavor resembles that of roasted pumpkin seed, and when roasted, its nutty flavor and waxy texture is similar to the pine nut. Research from the Institute of Plant Breeding, University of the Philippines at Los Banos describe pili nuts of high quality as large, round kernel, and a thin pulp and shell. The contents should have a white pulp, high in protein and oils with mild nutty ...
George Washington pushed for the growth of hemp as it was a cash crop commonly used to make rope and fabric. In May 1765 he noted in his diary about the sowing of seeds each day until mid-April. Then he recounts the harvest in October which he grew 27 bushels that year. It is sometimes supposed that an excerpt from Washington's diary, which reads "Began to seperate [sic] the Male from the Female hemp at Do.&-rather too late" is evidence that he was trying to grow female plants for the THC found in the flowers. However, the editorial remark accompanying the diary states that "This may arise from their [the male] being coarser, and the stalks larger"[132] In subsequent days, he describes soaking the hemp [133] (to make the fibers usable) and harvesting the seeds,[134] suggesting that he was growing hemp for industrial purposes, not recreational. George Washington also imported the Indian hemp plant from Asia, which was used for fiber and, by some growers, for intoxicating resin production. In a ...

The almond is native to the Mediterranean climate region of the Middle East, eastward as far as the Yamuna River in India.[9] It was spread by humans in ancient times along the shores of the Mediterranean into northern Africa and southern Europe, and more recently transported to other parts of the world, notably California, United States.[9]. The wild form of domesticated almond grows in parts of the Levant. The fruit of the wild forms contains the glycoside amygdalin, "which becomes transformed into deadly prussic acid (hydrogen cyanide) after crushing, chewing, or any other injury to the seed."[10]. Selection of the sweet type from the many bitter types in the wild marked the beginning of almond domestication.[11] It is unclear as to which wild ancestor of the almond created the domesticated species. Ladizinsky suggests the taxon Amygdalus fenzliana (Fritsch) Lipsky is the most likely wild ancestor of the almond in part because it is native of Armenia and western Azerbaijan where it was ...
Commercial factory farming operations often involve raising the hens in small, crowded cages, preventing the chickens from engaging in natural behaviors, such as wing-flapping, dust-bathing, scratching, pecking, perching, and nest-building. Such restrictions may lead to pacing and escape behavior.[101] Many hens confined to battery cages, and some raised in cage-free conditions, are debeaked to prevent them from harming each other and engaging in cannibalism. According to critics of the practice, this can cause hens severe pain to the point where some may refuse to eat and starve to death. Some hens may be forced to molt to increase egg quality and production level after the molting.[102] Molting can be induced by extended food withdrawal, water withdrawal, or controlled lighting programs. Laying hens often are slaughtered when reaching 100 to 130 weeks of age, when their egg productivity starts to decline.[103] Due to modern selective breeding, laying hen strains differ from meat production ...
Spirulina is a form of cyanobacterium, some of which are known to produce toxins such as microcystins, BMAA, and others. Some spirulina supplements have been found to be contaminated with microcystins, albeit at levels below the limit set by the Oregon Health Department.[24] Microcystins can cause gastrointestinal disturbances, and in the long term, liver damage.[1] The effects of chronic exposure to even very low levels of microcystins are of concern, because of the potential risk of toxicity to several organ systems[1] and possibly cancer.[24] These toxic compounds are not produced by spirulina itself,[25] but may occur as a result of contamination of spirulina batches with other toxin-producing blue-green algae. Because spirulina is considered a dietary supplement in the U.S., no active, industry-wide regulation of its production occurs and no enforced safety standards exist for its production or purity.[24] The U.S. National Institutes of Health describes spirulina supplements as "possibly ...
The raw nuts, though edible, have a skin which is astringent and unpleasant to eat when still moist; after drying for a time the thin skin loses its astringency but is still better removed to reach the white fruit underneath. Cooking dry in an oven or fire normally helps remove this skin. Chestnuts are traditionally roasted in their tough brown husks after removing the spiny cupules in which they grow on the tree, the husks being peeled off and discarded and the hot chestnuts dipped in salt before eating them. Roast chestnuts are traditionally sold in streets, markets and fairs by street vendors with mobile or static braziers.. The skin of raw peeled chestnuts can be relatively easily removed by quickly blanching the nuts after scoring them by a cross slit at the tufted end.[10] Once cooked, chestnuts acquire a sweet flavour and a floury texture similar to the sweet potato. The cooked nuts can be used for stuffing poultry, as a vegetable or in nut roasts. They can also be used in confections, ...
Among animals which produce one, the yolk (also known as the vitellus) is the nutrient-bearing portion of the egg whose primary function is to supply food for the development of the embryo. Some kinds of egg contain no yolk, for example because they are laid in situations where the food supply is sufficient (such as in the body of the host of a parasitoid) or because the embryo develops in the parent's body, which supplies the food, usually through a placenta. Reproductive systems in which the mother's body supplies the embryo directly are said to be matrotrophic; those in which the embryo is supplied by yolk are said to be lecithotrophic. In many species, such as all birds, and most reptiles and insects, the yolk takes the form of a special storage organ constructed in the reproductive tract of the mother. In many other animals, especially very small species such as some fishes and invertebrates, the yolk material is not in a special organ, but inside the ovum. As stored food, yolks are often ...
He also notes that several of the nuts began to germinate by the time they had been ten weeks at sea, precluding an unassisted journey of 100 days or more. However, the coconut variety Heyerdahl chose for his long sea voyage likely was of the large, fleshy, spherical niu vai type, which Harries observed to have a significantly shorter germination type and worse buoyancy than the uncultivated niu kafa type.[32] Therefore, Heyerdahl's observations cannot be considered conclusive when it comes to determining the independent dispersal ability of the uncultivated coconut.. Drift models based on wind and ocean currents have shown that coconuts could not have drifted across the Pacific unaided.[42] If they were naturally distributed and had been in the Pacific for a thousand years or so, then we would expect the eastern shore of Australia, with its own islands sheltered by the Great Barrier Reef, to have been thick with coconut palms: the currents were directly into, and down along this coast. However, ...

... poisoning is the most common type of fatal air poisoning in many countries.[28] Carbon monoxide is colorless, odorless, and tasteless, but highly toxic. It combines with hemoglobin to produce carboxyhemoglobin, which usurps the space in hemoglobin that normally carries oxygen, but is ineffective for delivering oxygen to bodily tissues. Concentrations as low as 667 ppm may cause up to 50% of the body's hemoglobin to convert to carboxyhemoglobin.[29] A level of 50% carboxyhemoglobin may result in seizure, coma, and fatality. In the United States, the OSHA limits long-term workplace exposure levels above 50 ppm.[30]. The most common symptoms of carbon monoxide poisoning may resemble other types of poisonings and infections, including symptoms such as headache, nausea, vomiting, dizziness, fatigue, and a feeling of weakness. Affected families often believe they are victims of food poisoning. Infants may be irritable and feed poorly. Neurological signs include confusion, ...

... s are neurotransmitters and neuromodulators that contain one amino group connected to an aromatic ring by a two-carbon chain (such as -CH2-CH2-). Examples are dopamine, serotonin and adrenaline. All monoamines are derived from aromatic amino acids like phenylalanine, tyrosine, and tryptophan by the action of aromatic amino acid decarboxylase enzymes. They are deactivated in the body by the enzymes known as monoamine oxidases which clip off the amine group. Monoaminergic systems, i.e., the networks of neurons that utilize monoamine neurotransmitters, are involved in the regulation of cognitive processes such as emotion, arousal, and certain types of memory. It has also been found that monoamine neurotransmitters play an important role in the secretion and production of neurotrophin-3 by astrocytes, a chemical which maintains neuron integrity and provides neurons with trophic support.[1] Drugs used to increase (or reduce) the effect of monoamine neurotransmitters are used ...
ADP cycling supplies the energy needed to do work in a biological system, the thermodynamic process of transferring energy from one source to another. There are two types of energy: potential energy and kinetic energy. Potential energy can be thought of as stored energy, or usable energy that is available to do work. Kinetic energy is the energy of an object as a result of its motion. The significance of ATP is in its ability to store potential energy within the phosphate bonds. The energy stored between these bonds can then be transferred to do work. For example, the transfer of energy from ATP to the protein myosin causes a conformational change when connecting to actin during muscle contraction. It takes multiple reactions between myosin and actin to effectively produce one muscle contraction, and, therefore, the availability of large amounts of ATP is required to produce each muscle contraction. For this reason, biological processes have evolved to produce efficient ways to replenishment the ...
