Different effects of trypsin inhibitors on intestinal gene expression of secretin and on pancreatic bicarbonate secretion in CCK-A-receptor-deficient rats. (1/16)

The effects of oral administration of two synthetic trypsin inhibitors (camostate and ONO-3403) and soybean trypsin inhibitor (SBTI) on cholecystokinin (CCK), secretin gene expression and pancreatic secretion were examined in CCK-A-receptor-deficient (OLETF) rats. The rats were fed chow containing 0.1% trypsin inhibitors for 7 days. To examine pancreatic secretion, the rats were prepared with cannulae to drain the bile and pancreatic juice separately, a duodenal cannula and an external jugular vein cannula. The animals were maintained in Bollman cages and the experiments were conducted 4 days after surgery. The levels of CCK mRNA were significantly increased by each treatment. The levels of secretin mRNA were significantly increased by camostate and SBTI, but not by ONO-3403. Bicarbonate secretion was significantly increased in rats treated with camostate and ONO-3403, but not SBTI, while protein secretion was not affected by any treatment. These observations suggest that increased bicarbonate secretion produced by synthetic trypsin inhibitors in CCK-A-receptor-deficient rats may not be due to secretin but due to ONO-3403 in the circulation.  (+info)

Conversion into GABA (gamma-aminobutyric acid) may reduce the capacity of L-glutamine as an insulin secretagogue. (2/16)

We have carried out a detailed examination of L-glutamine metabolism in rat islets in order to elucidate the paradoxical failure of L-glutamine to stimulate insulin secretion. L-Glutamine was converted by isolated islets into GABA (gamma-aminobutyric acid), L-aspartate and L-glutamate. Saturation of the intracellular concentrations of all of these amino acids occurred at approx. 10 mmol/l L-glutamine, and their half-maximal values were attained at progressively increasing concentrations of L-glutamine (0.3 mmol/l for GABA; 0.5 and 1.0 mmol/l for Asp and Glu respectively). GABA accumulation accounted for most of the 14CO2 produced at various L-[U-14C]glutamine concentrations. Potentiation by L-glutamine of L-leucine-induced insulin secretion in perifused islets was suppressed by malonic acid dimethyl ester, was accompanied by a significant decrease in islet GABA accumulation, and was not modified in the presence of GABA receptor antagonists [50 micromol/l saclofen or 10 micromol/l (+)-bicuculline]. L-Leucine activated islet glutamate dehydrogenase activity, but had no effect on either glutamate decarboxylase or GABA transaminase activity, in islet homogenates. We conclude that (i) L-glutamine is metabolized preferentially to GABA and L-aspartate, which accumulate in islets, thus preventing its complete oxidation in the Krebs cycle, which accounts for its failure to stimulate insulin secretion; (ii) potentiation by L-glutamine of L-leucine-induced insulin secretion involves increased metabolism of L-glutamate and GABA via the Krebs cycle (glutamate dehydrogenase activation) and the GABA shunt (2-oxoglutarate availability for GABA transaminase) respectively, and (iii) islet release of GABA does not seem to play an important role in the modulation of the islet secretory response to the combination of L-leucine and L-glutamine.  (+info)

Cyclic dermorphin tetrapeptide analogues obtained via ring-closing metathesis. (3/16)

The dermorphin-derived cyclic tetrapeptide analogues H-Tyr-c[D-Cys-Phe-Cys]NH(2) and H-Tyr-c[D-Cys-Phe-D-Cys]NH(2) are opioid agonists at the mu and delta receptor. To enhance the metabolic stability of these peptides, we replaced the disulfide bridge with a bis-methylene moiety. This was achieved by solid-phase synthesis of the linear precursor peptide containing allylglycine residues in place of the Cys residues, followed by ring-closing metathesis. In the case of the peptide with L-configuration in the 4-position both the cis and the trans isomer of the resulting olefinic peptides were formed, whereas the cis isomer only was obtained with the peptide having the D-configuration in position 4. Catalytic hydrogenation yielded the saturated -CH(2)-CH(2)- bridged peptides. In comparison with the cystine-containing parent peptides, all olefinic peptides showed significantly reduced mu and delta agonist potencies in the guinea pig ileum and mouse vas deferens assays. The -CH(2)-CH(2)-bridged peptide with l-configuration in the 4-position was equipotent with its cystine-containing parent in both assays, whereas the bis-methylene analogue with D-configuration in position 4 was 10-27-fold less potent compared to its parent. The effect of the disulfide replacements with the -CH=CH- and -CH(2)-CH(2)- moieties on the conformational behavior of these peptides was examined by theoretical conformational analysis which provided plausible explanations in terms of structural parameters for the observed changes in opioid activity.  (+info)

Panic-prone state induced in rats with GABA dysfunction in the dorsomedial hypothalamus is mediated by NMDA receptors. (4/16)

Rats with chronic inhibition of GABA synthesis and consequently enhanced glutamatergic excitation in the dorsomedial hypothalamus (DMH) develop panic-like responses, defined as tachycardia, tachypnea, hypertension, and increased anxiety as measured by a social interaction (SI) test, after intravenous sodium lactate infusions, a phenomenon similar to patients with panic disorder. Therefore, the present studies tested the role of the postsynaptic NMDA and AMPA type glutamatergic receptors in the lactate-induced panic-like responses in these rats. Rats were fit with femoral arterial and venous catheters and Alzet pumps [filled with the GABA synthesis inhibitor L-allylglycine (L-AG; 3.5 nmol/0.5 microl per hour) or its inactive isomer D-AG] into the DMH. After 4-5 d of recovery only those rats with L-AG pumps exhibited panic-like responses to lactate infusions. Using double immunocytochemistry, we found that rats exhibiting panic-like responses (e.g., L-AG plus lactate) had increased c-Fos immunoreactivity in DMH neurons expressing the NMDA receptor 1 (NR1) subunit, but not those expressing the glutamate receptor 2 and 3 subunits of the AMPA receptors. To confirm this pharmacologically, we tested another group of rats implanted with l-AG pumps with intravenous lactate infusions preceded by injections of either NMDA [aminophosphonopentanoic acid (AP-5) or (+)-5-methyl-10,11-dihydro-5H-dibenzo [a,d]cyclohepten-5,10-imine maleate (MK-801)] or non-NMDA [CNQX or 4-(8-methyl-9H-1,3-dioxolo[4,5-h][2,3]benzodazepin-5-yl)-benzenamine dihydrochloride (GYKI52466)] antagonists into the DMH. Injections of NMDA, but not non-NMDA, antagonists into the DMH resulted in dose-dependent blockade of the tachycardia, tachypnea, hypertension, and SI responses after lactate infusions. These results suggest that NMDA, and not non-NMDA, type glutamate receptors regulate lactate-induced panic-like responses in rats with GABA dysfunction in the DMH.  (+info)

Neural pathways underlying lactate-induced panic. (5/16)

Panic disorder is a severe anxiety disorder characterized by susceptibility to induction of panic attacks by subthreshold interoceptive stimuli such as 0.5 M sodium lactate infusions. Although studied for four decades, the mechanism of lactate sensitivity in panic disorder has not been understood. The dorsomedial hypothalamus/perifornical region (DMH/PeF) coordinates rapid mobilization of behavioral, autonomic, respiratory and endocrine responses to stress, and rats with disrupted GABA inhibition in the DMH/PeF exhibit panic-like responses to lactate, similar to panic disorder patients. Utilizing a variety of anatomical and pharmacological methods, we provide evidence that lactate, via osmosensitive periventricular pathways, activates neurons in the compromised DMH/PeF, which relays this signal to forebrain limbic structures such as the bed nucleus of the stria terminalis to mediate anxiety responses, and specific brainstem sympathetic and parasympathetic pathways to mediate the respiratory and cardiovascular components of the panic-like response. Acutely restoring local GABAergic tone in the DMH/PeF blocked lactate-induced panic-like responses. Autonomic panic-like responses appear to be a result of DMH/PeF-mediated mobilization of sympathetic responses (verified with atenolol) and resetting of the parasympathetically mediated baroreflex. Based on our findings, DMH/PeF efferent targets such as the C1 adrenergic neurons, paraventricular hypothalamus, and the central amygdala are implicated in sympathetic mobilization; the nucleus of the solitary tract is implicated in baroreflex resetting; and the parabrachial nucleus is implicated in respiratory responses. These results elucidate neural circuits underlying lactate-induced panic-like responses and the involvement of both sympathetic and parasympathetic systems.  (+info)

Modelling of tumour--host coexistence In vitro in the presence of serine protease inhibitors. (8/16)

The activities of cell surface serine proteases are markedly enhanced in malignant tumours. Proteolytic degradation of the extracellular matrix and basal membrane of normal cells is an important event for tumour cell growth and invasion. Two well-known broad-spectrum inhibitors of serine protease, Foy-305 and Ono-3403, were evaluated for their ability to affect the growth rate and survival of MCF7 breast cancer cells co-cultured with MRC5 lung fibroblasts as feeder cells in the absence of serum. Flow cytometry and differential staining demonstrated that in the mixed culture, the rate of tumor growth was dependent upon the presence of the feeder MRC5 lung fibroblasts and could be obviated by the additional presence of the inhibitors of serine proteases.  (+info)

Acute heart failure (AHF) is characterized by inadequate cardiac output (CO), congestive symptoms, poor peripheral perfusion and end-organ dysfunction. Treatment often includes a combination of diuretics, oxygen, positive pressure ventilation, inotropes and vasodilators or vasopressors. Lactate is a marker of illness severity but is also an important metabolic substrate for the myocardium at rest and during stress. We tested the effects of half-molar sodium lactate infusion on cardiac performance in AHF. We conducted a prospective, randomised, controlled, open-label, pilot clinical trial in 40 patients fulfilling two of the following three criteria for AHF: (1) left ventricular ejection fraction |40%, (2) acute pulmonary oedema or respiratory failure of predominantly cardiac origin requiring mechanical ventilation and (3) currently receiving vasopressor and/or inotropic support. Patients in the intervention group received a 3 ml/kg bolus of half-molar sodium lactate over the course of 15 minutes
Tasks of attention and impulse control in humans have excellent rodent counterparts. In particular, the 5-choice serial reaction time task (5CSRTT), which is the most widely used task measuring impulsive action and attention performance, has been instrumental in defining the underlying neuroanatomy, neurochemistry and genes pertaining to these cognitive functions.. In the 5CSRTT, mice are required to respond to a brief light stimulus in one of five response apertures. The number of premature responses before the stimulus light switches on is a measure of impulsivity. Omissions of responding, accuracy of responding and the intra-individual variability in response latencies are measures of attention.. ...

As part of a program investigating cyclic peptides with an internal aromatic hydrophobic scaffold as potential novel anti-bacterial agents, we explored the synthesis of simple tyrosine-based systems. These were prepared via key intermediates containing internal allylglycine and allyltyrosine residues for subsequent ring closing metathesis reactions. Although the resulting anti-bacterial activity against Staphylococcus aureus was modest, this represents a novel and simple route to this class of compounds. One intermediate acyclic dipeptide precursor showed good activity against S. aureus with an MIC of 7.8 µg/mL.

The dopamine D4 receptor is critical for attention. Dopamine and D4 receptors can synchronize different neural networks that might otherwise not be synchronized together, and to tune their frequency of activity. Frequency is how fast the neurons are firing. Higher frequencies are more metabolically demanding. When you are attending to something, dopamine and the D4 receptor make the circuits involved in what you are paying attention to shift to a higher frequency, the gamma frequency, which is 30-80 hz. The D4 receptors are located in certain cells in the brain called parvalbumin expressing GABAergic interneurons. Those cells develop post-nataly as the individuals capacity for attention develops. By 4 to 5 months of age babies begin to be able to pay attention to things. Problems with methylation could affect attention through this process. Certain mutations in the gene for the D4 receptor is the biggest risk for developing ADHD. When asked if this connection between the parvalbumin expressing ...

Glutamin se šteje med semi-esencialne aminokisline, saj je v določenih okoliščinah človeško telo ne more proizvesti dovolj, da bi zadovoljili naše potrebe, še posebej pa potrebe športnikov. Glutamin je najbolj običajna amino kislina v krvi in mišičnem tkivu in pripomore k številnih fiziološkimi procesi v človeškem telesu. Glutamin ima antikataboličnimi učinek in stimulira regeneracijo mišic po treningu. Poleg tega je glutamin močan antioksidant: ljudje, ki ga uživajo imajo tudi boljšo odpornost proti prehladu. Športniki pa opazijo več moči in boljšo vzdržljivost. Glutamin tudi upočasnjuje procese staranja.

In 2001, the German Federal Institute for Risk Assessment (Bundesinstitut für Risikobewertung, BfR) objected to the addition of isolated theanine to beverages.[39][40] The institute stated the amount of theanine consumed by regular drinkers of tea or coffee is virtually impossible to determine. While it was estimated the quantity of green tea consumed by the average Japanese tea drinker per day contains about 20 mg of the substance, there are no studies measuring the amount of theanine being extracted by typical preparation methods, or the percentage lost by discarding the first infusion. Therefore, with the Japanese being exposed to possibly much less than 20 mg per day, and Europeans presumably even less, it was the opinion of the BfR that pharmacological reactions to drinks typically containing 50 mg of theanine per 500 milliliters could not be excluded-reactions such as impairment of psychomotor skills and amplification of the sedating effects of alcohol and hypnotics.[41] In 2006, a study ...
GAD67 and GAD65 are also regulated differently post-translationally. Both GAD65 and GAD67 are regulated via phosphorylation of a dynamic catalytic loop,[10][11] but the regulation of these isoforms differs; GAD65 is activated by phosphorylation while GAD67 is inhibited by phosphorylation. GAD67 is predominantly found activated (~92%), whereas GAD65 is predominantly found inactivated (~72%).[12] GAD67 is phosphorylated at threonine 91 by protein kinase A (PKA), while GAD65 is phosphorylated, and therefore regulated by, protein kinase C (PKC). Both GAD67 and GAD65 are also regulated post-translationally by Pyridoxal 5'-phosphate (PLP); GAD is activated when bound to PLP and inactive when not bound to PLP.[12] Majority of GAD67 is bound to PLP at any given time, whereas GAD65 binds PLP when GABA is needed for neurotransmission.[12] This reflects the functional properties of the two isoforms; GAD67 must be active at all times for normal cellular functioning, and is therefore constantly activated by ...
Regulation of GS only occurs in prokaryotes.[24] GS is subject to reversible covalent modification. Tyr397 of all 12 subunits can undergo adenylylation or deadenylylation by adenylyl transferase (AT), a bifunctional regulatory enzyme.[24] Adenylylation is a post-translational modification involving the covalent attachment of AMP to a protein side chain. Each adenylylation requires an ATP and complete inhibition of GS requires 12 ATP. Deadenylylation by AT involves phosphorolytic removal of the Tyr-linked adenylyl groups as ADP. AT activity is influenced by the regulatory protein that is associated with it: PII, a 44-kD trimer.[24] PII also undergoes post-translational modification by uridylyl transferase, thus PII has two forms. The state of PII dictates the activity of adenylyl transferase. If PII is not uridylylated, then it will take on the PIIA form. The AT:PIIA complex will deactivate GS by adenylylation. If PII is uridylylated, then it will take on the PIID form. The AT:PIID complex will ...
Besides the nervous system, GABA is also produced at relatively high levels in the insulin-producing β-cells of the pancreas. The β-cells secrete GABA along with insulin and the GABA binds to GABA receptors on the neighboring islet α-cells and inhibits them from secreting glucagon (which would counteract insulin's effects).[25] GABA can promote the replication and survival of β-cells[26][27][28] and also promote the conversion of α-cells to β-cells, which may lead to new treatments for diabetes.[29] GABA has also been detected in other peripheral tissues including intestines, stomach, Fallopian tubes, uterus, ovaries, testes, kidneys, urinary bladder, the lungs and liver, albeit at much lower levels than in neurons or β-cells. GABAergic mechanisms have been demonstrated in various peripheral tissues and organs, which include the intestines, the stomach, the pancreas, the Fallopian tubes, the uterus, the ovaries, the testes, the kidneys, the urinary bladder, the lungs, and the liver.[30] ...
... (marketed as Depamide by Sanofi-Aventis) is a carboxamide derivative of valproic acid used in the treatment of epilepsy and some affective disorders. It is rapidly metabolised (80%) to valproic acid (another anticonvulsant) but has anticonvulsant properties itself. It may produce more stable plasma levels than valproic acid or sodium valproate and may be more effective at preventing febrile seizures. However, it is over one hundred times more potent as an inhibitor of liver microsomal epoxide hydrolase. This makes it incompatible with carbamazepine and can affect the ability of the body to remove other toxins. Valpromide is no safer during pregnancy than valproic acid. Valpromide is formed through the reaction of valproic acid and ammonia via an intermediate acid chloride. In pure form, valpromide is a white crystalline powder and has melting point 125-126 °C. It is practically insoluble in water but soluble in hot water. It is available on the market in some European countries. ...
... is an azo dye that is used as a dye-stuff. It is a direct dye for cotton textiles.[3] In biosciences, it is used as vital stain to selectively colour dead tissues or cells blue. Live cells or tissues with intact cell membranes are not coloured. Since cells are very selective in the compounds that pass through the membrane, in a viable cell trypan blue is not absorbed; however, it traverses the membrane in a dead cell. Hence, dead cells appear as a distinctive blue colour under a microscope. Since live cells are excluded from staining, this staining method is also described as a dye exclusion method. This dye may be a cause of certain birth defects, such as encephalocele.[citation needed] ...
Glutamate is the most abundant excitatory neurotransmitter in the vertebrate nervous system.[21] At chemical synapses, glutamate is stored in vesicles. Nerve impulses trigger release of glutamate from the presynaptic cell. Glutamate acts on ionotropic and metabotropic (G-protein coupled) receptors.[21] In the opposing postsynaptic cell, glutamate receptors, such as the NMDA receptor or the AMPA receptor, bind glutamate and are activated. Because of its role in synaptic plasticity, glutamate is involved in cognitive functions such as learning and memory in the brain.[22] The form of plasticity known as long-term potentiation takes place at glutamatergic synapses in the hippocampus, neocortex, and other parts of the brain. Glutamate works not only as a point-to-point transmitter, but also through spill-over synaptic crosstalk between synapses in which summation of glutamate released from a neighboring synapse creates extrasynaptic signaling/volume transmission.[23] In addition, glutamate plays ...
Neurons that produce GABA as their output are called GABAergic neurons, and have chiefly inhibitory action at receptors in the adult vertebrate. Medium spiny cells are a typical example of inhibitory central nervous system GABAergic cells. In contrast, GABA exhibits both excitatory and inhibitory actions in insects, mediating muscle activation at synapses between nerves and muscle cells, and also the stimulation of certain glands.[4] In mammals, some GABAergic neurons, such as chandelier cells, are also able to excite their glutamatergic counterparts.[5] GABAA receptors are ligand-activated chloride channels: when activated by GABA, they allow the flow of chloride ions across the membrane of the cell. Whether this chloride flow is depolarizing (makes the voltage across the cell's membrane less negative), shunting (has no effect on the cell's membrane potential), or inhibitory/hyperpolarizing (makes the cell's membrane more negative) depends on the direction of the flow of chloride. When net ...
... is a non-selective and irreversible inhibitor of the enzyme monoamine oxidase (MAO). It inhibits both of the respective isoforms of MAO, MAO-A and MAO-B, and does so almost equally, with slight preference for the former. By inhibiting MAO, phenelzine prevents the breakdown of the monoamine neurotransmitters serotonin, melatonin, norepinephrine, epinephrine, and dopamine, as well as the trace amine neuromodulators such as phenethylamine, tyramine, octopamine, and tryptamine. This leads to an increase in the extracellular concentrations of these neurochemicals and therefore an alteration in neurochemistry and neurotransmission. This action is thought to be the primary mediator in phenelzine's therapeutic benefits. Phenelzine and its metabolites also inhibit at least two other enzymes to a lesser extent, of which are alanine transaminase (ALA-T),[21] and γ-Aminobutyric acid transaminase (GABA-T),[22] the latter of which is not caused by phenelzine itself, but by a phenelzine metabolite ...
Penemuan penislin selalu dikaitkan dengan ilmuwan Skotlandia, Alexander Fleming pada 1929, walaupun sebenarnya banyak ilmuwan lain yang telah mencatat efek antibakteri sebelum Fleming.[2]. Fleming, dalam laboratoriumnya di Rumah Sakit Santa Maria (kini merupakan salah satu rumah sakit pendidikan di London), mencatat adanya lingkaran hambatan (zona bening) pada pertumbuhan bakteri di piringan kultur Staphylococcus. Fleming menyimpulkan bahwa hambatan itu dikarenakan sebuah subtansi penghambat pertumbuhan dan menghancurkan bakteri. Ia kemudian menumbuhkan sebuah kultur murni dan menemukan Penicillium yang kemudian dikenal sebagai Penicillium chrysogenum. Fleming memberikan istilah "penisilin" untuk menggambarkan hasil filtrasi dari kultur mikrobiologis Penicillium.[2]. Walaupun di tahapan awal ini, penisilin ditemukan efektif melawan bakteri Gram positif dan tidak efektif pada Gram negatif dan jamur. Fleming optimis bahwa penisilin akan menjadi disinfektan yang sangat berguna, berpotensi tinggi ...
