A study of the relative bioavailability of cysteamine hydrochloride, cysteamine bitartrate and phosphocysteamine in healthy adult male volunteers. (1/274)

AIMS: Cysteamine, the only drug available for the treatment of cystinosis in paediatric patients, is available as the hydrochloride, the bitartrate and as sodium phosphocysteamine salts. It has been suggested that cysteamine bitartrate and phosphocysteamine are better tolerated and may have a better bioavailability than cysteamine hydrochloride. This has, however, never been demonstrated. METHODS: We compared the pharmacokinetics and tolerance of these three formulations of cysteamine in 18 healthy adult male volunteers in a double-blind, latin-square, three-period, single oral dose cross-over relative bioavailability study. RESULTS: No statistical difference was found between relative bioavailabilities, AUC (0, infinity) (geometric mean and s.d. in micromol l(-1) h: 169+/-51, 158+/-46, 173+/-49 with cysteamine hydrochloride, phosphocysteamine and cysteamine bitartrate respectively), Cmax (geometric mean and s.d. in micromol l(-1); 66+/-25.5, 59+/-12, 63+/-20) and tmax (median and range in h: 0.88 (0.25-2), 1.25 (0.25-2), 0.88 (0.25-2)) with each of the three forms of cysteamine tested. Bioequivalence statistics (90% confidence intervals) showed non equivalence of Cmax of cysteamine base as the only non equivalence of pharmacokinetics between the three formulations: 90% CI for Cmax relative ratios to cysteamine hydrochloride were [75.6-105.81 for phosphocysteamine and [74.2-124.2] for cysteamine bitartrate. The only significant adverse event was vomiting whose frequency was inversely correlated with body weight (Spearman's r=-0.76, P<0.001). The nature of the salt tested did not influence vomiting. CONCLUSIONS: While none of the three forms of cysteamine tested has a clear advantage over the others in terms of pharmacokinetics and tolerance profile, this should now however be addressed in patients treated for cystinosis during repeat administrations.  (+info)

Exogenous cysteamine increases basal pancreatic exocrine secretion in the rat. (2/274)

To determine whether exocrine pancreatic secretion is regulated by endogenous somatostatin, somatostatin deficiency was induced by cysteamine. Rats were subcutaneously administered a single dose of cysteamine (30 mg/100 g body weight) 12 hr before experiment. Anesthetized rats were prepared with cannulation into bile duct, pancreatic duct, duodenum, and jugular vein and pancreatic juice was collected. For in vitro study, isolated pancreata of rats, pretreated with cysteamine, were perfused with an intraarterial infusion of Krebs-Henseleit solution (37 degrees C) at 1.2 mL/min, and pancreatic juice was collected in 15-min samples. In vivo experiment of the rat, the mean basal pancreatic secretions, including volume, bicarbonate, and protein output were significantly increased from 18.4+/-0.5 microL/30 min, 0.58+/-0.05 microEq/30 min, and 214.0+/-26.1 microg/30 min to 51.6+/-3.7 microL/30 min, 1.52+/-0.11 microEq/30 min, and 569.8+/-128.9 microg/30 min, respectively (p<0.05). In the isolated perfused pancreas, cysteamine also resulted in a significant increase in basal pancreatic secretion (p<0.05). Simultaneous intraarterial infusion of octreotide (10 pmol/hr) to isolated pancreata partially reversed the effect of cysteamine on basal pancreatic secretion. These findings suggest that endogenous somatostatin play an important role on the regulation of basal pancreatic exocrine secretion.  (+info)

Male pronuclear formation in denuded porcine oocytes after in vitro maturation in the presence of cysteamine. (3/274)

The present study was conducted to examine effects of cysteamine in culture medium on progression of meiosis, glutathione (GSH) content, kinase activities (histone H1 kinase and mitogen-activated protein kinase), and male pronuclear formation after in vitro insemination of cumulus-denuded oocytes (DOs) in the pig. DOs, obtained by mechanically removing cells from cumulus-oocyte complexes (COCs) with a small-bore pipette, were cultured for 45 h in TCM199 supplemented with sodium pyruvate, gonadotropins, estradiol, and 10% porcine follicular fluid, with or without cysteamine (150 microM). Maturation rates of DOs cultured with and without cysteamine were not different (60-70%) but were significantly lower than those of COCs (90-100%) (p < 0.05). GSH content of matured DOs cultured with cysteamine was significantly higher than that of DOs cultured without cysteamine (p < 0.05). Values for both types of kinase activity in matured DOs cultured with and without cysteamine were not different (p > 0.05). After in vitro insemination, DOs cultured with cysteamine showed significantly higher rates of male pronuclear formation (80.3 +/- 3.0%) than DOs cultured without cysteamine (16.4 +/- 0.5%) (p < 0.05). These results indicate that the addition of cysteamine to culture medium increased oocyte GSH content and promoted male pronuclear formation after sperm penetration of porcine DOs but had no effects on their maturation rates or kinase activities.  (+info)

New method for determining cystine in leukocytes and fibroblasts. (4/274)

BACKGROUND: Cystinosis is a rare inborn error of cystine transport, leading to accumulation of cystine in the lysosomes. To diagnose cystinosis and monitor treatment with cysteamine, adequate measurements of cystine concentrations in leukocytes and cultured fibroblasts are required. METHODS: Cells were sonicated in the presence of excess N-ethylmaleimide to prevent oxidation of cysteine to cystine and disulfide exchange reactions of cystine with available sulfhydryl moieties. Cystine was measured as cysteine after reduction with sodium borohydride and derivatization with monobromobimane, followed by separation with automated HPLC and fluorescence detection. RESULTS: The assay was linear to 200 micromol/L cysteine. Within-run and day-to-day (total) imprecision (CV) was <5%, and the detection limit was 0.3 micromol/L. Added cysteine, up to 200 micromol/L, was completely removed, and recovery of added cystine was 69-86%. Cystine was stable for at least 2 months in leukocytes frozen in liquid nitrogen and stored at -80 degrees C CONCLUSIONS: Oxidation of cysteine to cystine and disulfide exchange reactions of cystine with sulfhydryl moieties are prevented by N-ethylmaleimide. The detection limit for the determination of cystine is adequate to measure cystine in leukocytes and cultured fibroblasts for diagnosis of cystinosis and monitoring treatment with cysteamine.  (+info)

Selective incorporation and specific cytocidal effect as the cellular basis for the antimelanoma action of sulphur containing tyrosine analogs. (5/274)

Tyrosine analogs are good candidates for developing melanoma chemotherapy because melanogenesis is inherently toxic and uniquely expressed in melanocytic cells. Sulphur containing substrate (tyrosine) analogs, N-acetyl-4-S-cysteaminylphenol (NAcCAP) and N-propionyl-4-S-cysteaminylphenol (NPrCAP), have been shown to have potent antimelanoma activity in mice bearing melanoma. Both NAcCAP and NPrCAP show selective cytotoxicity towards melanoma cell lines. But the mechanism leading to selectivity is not clear as these drugs are also toxic to other cell lines to a lesser extent. Here we show that these drugs have both cytostatic and cytocidal effects, which could account for this. Cytostatic effect is suggested by DNA flow cytometry. The drug causes cell cycle changes in four human cell lines (normal skin fibroblasts, HeLa cells, and melanoma cell lines, C32 and SK-MEL-23) in a dose-dependent manner blocking cells in S phase with concomitant decrease in the number of cells in G1 phase. There is also a gradual decrease in cells in G2 + M phases. The dose-concentration curves give IC50 values in the range of 50-400 microM and the melanotic melanoma cell line SK-MEL-23 has the lowest IC50 value consistent with our hypothesis that these drugs are selective towards melanoma cells. The concentration-dependent accumulation of cells in S phase suggest a cytostatic effect as a consequence of inhibition of DNA synthesis in agreement with [3H] thymidine incorporation assay. There is a highly specific uptake of [14C]NAcCAP and irreversible damage to DNA synthesis machinery in SK-MEL-23 cells, indicating a melanotic-specific cytocidal effect as well. Trypan blue exclusion study and competitive inhibition assay indicated that visible cytocidal effect occurs slowly and oxidative stress resulting from tyrosinase mediated oxidation of the drug appears to be the underlying mechanism. The primary antimelanoma effect of cysteaminylphenols derives from a selective cytostatic effect, but is followed by a specific cytocidal action rendering the drugs useful for targeted melanoma chemotherapy.  (+info)

Binding of an antibody mimetic of the human low density lipoprotein receptor to apolipoprotein E is governed through electrostatic forces. Studies using site-directed mutagenesis and molecular modeling. (6/274)

Monoclonal antibody 2E8 is specific for an epitope that coincides with the binding site of the low density lipoprotein receptor (LDLR) on human apoE. Its reactivity with apoE variants resembles that of the LDLR: it binds well with apoE3 and poorly with apoE2. The heavy chain complementarity-determining region (CDRH) 2 of 2E8 shows homology to the ligand-binding domain of the LDLR. To define better the structural basis of the 2E8/apoE interaction and particularly the role of electrostatic interactions, we generated and characterized a panel of 2E8 variants. Replacement of acidic residues in the 2E8 CDRHs showed that Asp(52), Glu(53), and Asp(56) are essential for high-affinity binding. Although Asp(31) (CDRH1), Glu(58) (CDRH2), and Asp(97) (CDRH3) did not appear to be critical, the Asp(97) --> Ala variant acquired reactivity with apoE2. A Thr(57) --> Glu substitution increased affinity for both apoE3 and apoE2. The affinities of wild-type 2E8 and variants for apoE varied inversely with ionic strength, suggesting that electrostatic forces contribute to both antigen binding and isoform specificity. We propose a model of the 2E8.apoE immune complex that is based on the 2E8 and apoE crystal structures and that is consistent with the apoE-binding properties of wild-type 2E8 and its variants. Given the similarity between the LDLR and 2E8 in terms of specificity, the LDLR/ligand interaction may also have an important electrostatic component.  (+info)

Aminoacyl-SNACs as small-molecule substrates for the condensation domains of nonribosomal peptide synthetases. (7/274)

BACKGROUND: Nonribosomal peptide synthetases (NRPSs) are large multidomain proteins that catalyze the formation of a wide range of biologically active natural products. These megasynthetases contain condensation (C) domains that catalyze peptide bond formation and chain elongation. The natural substrates for C domains are biosynthetic intermediates that are covalently tethered to thiolation (T) domains within the synthetase by thioester linkages. Characterizing C domain substrate specificity is important for the engineered biosynthesis of new compounds. RESULTS: We synthesized a series of aminoacyl-N-acetylcysteamine thioesters (aminoacyl-SNACs) and show that they are small-molecule substrates for NRPS C domains. Comparison of rates of peptide bond formation catalyzed by the C domain from enterobactin synthetase with various aminoacyl-SNACs as downstream (acceptor) substrates revealed high selectivity for the natural substrate analog L-Ser-SNAC. Comparing L- and D-Phe-SNACs as upstream (donor) substrates for the first C domain from tyrocidine synthetase revealed clear D- versus L-selectivity. CONCLUSIONS: Aminoacyl-SNACs are substrates for NRPS C domains and are useful for characterizing the substrate specificity of C domain-catalyzed peptide bond formation.  (+info)

Contribution of dithiol ligands to in vitro and in vivo trypanocidal activities of dithiaarsanes and investigation of ligand exchange in an aqueous solution. (8/274)

Twelve new dithiaarsanes were evaluated for their in vitro and in vivo trypanocidal properties in regard to their three parent molecules, 4-amino-phenylarsenoxide, melarsenoxide, and 4-dansylamino-phenylarsenoxide. The most potent dithiaarsane, compound 2b, had a minimum effective concentration of 1.5 nM after 48 h of incubation and at a dose of 0.39 micromol/kg of body weight (0.2 mg/kg) administered subcutaneously cured 100% of mice acutely infected with Trypanosoma brucei brucei CMP. With this model, the chemotherapeutic index of compound 2b was 512, compared to 256 for melarsamine dihydrochloride (Cymelarsan) under the same conditions. With a chronic infection produced by T. brucei brucei GVR, compound 2b cured 100% of mice after treatment at a dose of 25 micromol/kg (12.5 mg/kg) for 4 consecutive days, whereas melarsamine dihydrochloride and potassium melarsonyl (Trimelarsan) cured less than 50% mice at this dose. For both acute and late-stage infections, dithiaarsanes having a melaminophenyl ring exhibited the most-potent trypanocidal activity. Compound 2b is thus one of the most active organoarsenicals described in a mouse trypanosomiasis model. Considering that the main intracellular targets of organoarsenicals are thiol groups, we studied the possibility of ligand exchange between Cymelarsan and several dithiols. In aqueous solution, we observed a rapid exchange of cysteamine from melarsamine with free cysteamine and also with various dithiols always in favor of more stable cyclic derivatives. These ligand exchanges suggest the ability of trivalent organoarsenicals to react with targets such as trypanothione and dihydrolipoic acid. Among several ligands, a 1,3-dimercaptopropane moiety appeared the most suitable for trypanocidal activity.  (+info)

0068]Patients with cystinosis are required to ingest oral cysteamine (Cystagon) every 6 hours, day and night. When taken regularly, cysteamine can deplete intracellular cystine by up to 90% (as measured in circulating white blood cells), and this has been shown to reduce the rate of progression to kidney failure/transplantation and also to obviate the need for thyroid replacement therapy. Unfortunately, because of the strict treatment regimen and the associated symptoms, nonadherence with cysteamine therapy remains a problem, particularly among adolescent and young adult patients. Certainly, by reducing the frequency of required cysteamine dosing adherence can be improved. The disclosure shows a strong statistical association between the maximum plasma concentration (Cmax) of cysteamine and AOC measurements for leukocyte cystine (P,0.001). A higher Cmax is achieved after delivery of cysteamine into the small intestine than when infused into the stomach or colon; this may be due to improved ...
Efficacy of immediate-release cysteamine bitartrate was demonstrated in open-label clinical trials of cysteamine hydrochloride and phosphocysteamine.. An open-label clinical trial of cysteamine hydrochloride was conducted in 94 pediatric patients (mainly from the United States) with nephropathic cystinosis. Patients were treated with increasing doses of cysteamine hydrochloride (mean dose 54 mg/kg per day) to attain WBC cystine concentrations of less than 2 nmol ½ cystine/mg protein 5 to 6 hours post-dose. The clinical outcomes were compared with a historical control group of 17 pediatric patients who had been in the placebo group of a randomized placebo-controlled trial of ascorbic acid. Cysteamine-treated patients had been diagnosed at a mean age of 22 months and had a mean age of 46 months old at study entry; placebo patients had been diagnosed at about 29 months and had a mean age of about 52 months old at trial entry. The principal measures of effectiveness were serum creatinine and ...
Levin et al (2014) recently reported on a study exploring the impact of combined oral cysteamine bitartrate (60 mg/kg per day) and N-acetylcysteine (60 mg/kg per day) in patients with neuronal ceroid lipofuscinosis (n=10, age range: 6 months to 3 years old).. Assessments took place every 6-12 months until the patients had an isoelectric EEG or were too ill to travel. Electroretinography, brain MRI/MRS, electron microscopic analyses of leukocytes for granular osmiophilic deposits (GRODs), and physical/ neurodevelopmental assessments on the Denver scale were also performed.. Combination therapy with cysteamine bitartrate and N-acetylcysteine was associated with delay of isoelectric EEG (average time to isoelectric EEG was 52 months compared with 36 months in previous publications), depletion of GRODs, and subjective benefits as reported by parents and physicians (less irritability, improved alertness).. Oral cysteamine bitartrate and N-acetylcysteine for patients with infantile neuronal ceroid ...
This is a multi-center, open-label, randomized, cross-over study to determine whether steady-state, twice a day treatment with Cysteamine Bitartrate Delayed-release Capsules(RP103) results in comparable depletion of white blood cell (WBC) cystine levels compared to the existing four times a day cysteamine treatment. It will involve up to 20 clinic visits plus intermittent home use of the RP103. Most of these clinic visits occur in clusters of 3-4 consecutive days. Eligible patients will be offered enrollment into a long-term follow up study ...

Cystagon (cysteamine bitartrate), an oral immediate-release therapy, was approved in 1994 by the FDA. If it used as directed, most late complications of cystinosis can be delayed or perhaps avoided. One reference suggested that those affected can live to at least 50 years. But Cystagon must be taken every six hours and can cause a repulsive body odor, can cause nausea and vomiting, and increases gastric acid production.. Recently the FDA approved a new drug with the same active ingredient, cysteamine bitartrate, but in an enteric coated delayed-release formulation named Procysbi. Indicated for management of nephritic cystinosis in persons ages 6 years and older, Procysbi is available as a capsule in 25-mg and 75-mg strengths that can be administered 12 hours apart instead of every six hours. The advantage is obvious - patients maintain a normal sleep interval and avoid the need for a mid-day dose.. Procysbi was studied in 6 clinical trials. Three studied only healthy volunteers. The other three ...

Spurred by the alleged relevance of the thia-Michael reaction in the bioactivity of various classes of cinnam(o)yl natural products and by the development of a quick NMR assay to study this reaction, we have carried out a systematic study of the "native" reactivity of these compounds with dodecanethiol and cysteamine as models, respectively, of simple thiols and reactive protein thiols that can benefit from iminium ion catalysis in Michael reactions. Cinnamoyl esters and amides, as well as cinnamyl ketones and oximes, did not show any reactivity with the two probe thiols, while cinnamaldehyde (1a) reacted with cysteamine to afford a mixture of a thiazoline derivative and compounds of multiple addition, and with aliphatic thiols to give a single bis-dithioacetal (6 ...

The foundational aspect that must be addressed is the metabolic mitochondrial defect, and this involves radically reducing the non-fiber carbohydrates in your diet and increasing high-quality fats. You may need up to 85 percent of your dietary calories from healthy fats, along with a moderate amount of high-quality protein, as excessive protein can also trigger cancer growth.. Thats really the solution. If you dont do that, other treatments, including 3BP, probably will not work. (However, I believe that if youre in nutritional ketosis and then add 3BP, you may be able to reverse just about any cancer. Thats my current impression. It may be flawed, and I will revise it as necessary, but everything Ive seen so far points in that direction.). Its important to remember that glucose is an inherently "dirty" fuel as it generates far more reactive oxygen species (ROS) than burning fat. But to burn fat, your cells must be healthy and normal. Cancer cells lack the metabolic flexibility to burn fat ...
Where do I get my "Protein"? I am feeling tired, I must not be getting enough protein.. What is a protein anyway? What is a complete protein? Proteins are macronutrients and large building blocks. They must be broken down to be used to make muscle, connective tissue, and enzymes that the body uses to function. They are broken down into amino acids. There are nine that humans need to eat that cannot be synthesized: phenylalanine, valine, threonine, tryptophan, methionine, leucine, isoleucine, lysine and histidine. All other amino acids are assimilated by the body for its needs in various functions. Energy is not really one of them. Any excess ingested is turned into fat. If one ingests excessive protein one will not become excessively muscular. Only repeated contraction of a muscle can stimulate the production of more muscle fibers. One does not need to worry about which amino acids they are ingesting. Animal protein contains all of the essential amino acids as does beans and seeds. All plants ...

Abstract Cystamine has shown significant neuroprotective properties in preclinical studies of Parkinsons disease (PD) and Huntingtons disease (HD). Cysteamine, its FDA-approved reduced form, is scheduled to be tested for clinical efficacy in HD patients. Here, we studied the key cystamine metabolites, namely cysteamine, hypotaurine and taurine, as well as cysteine, in order to identify which one is more distinctively responsible for the neuroprotective action of cystamine. After a single administration of cystamine (10, 50 or 200 mg/kg), naïve mice were perfused with phosphate-buffered saline (PBS) at 1, 3, 12, 24 or 48 h post-injection and brain and plasma samples were analyzed by two distinct HPLC methods. Although plasma levels remained under the detection threshold, significant increases in cysteamine brain levels were detected with the 50 and 200 mg/kg doses in mice perfused 1 and 3 h following cystamine injection. To further assess cysteamine as the candidate molecule for pre-clinical ...

There are three forms of the condition: Nephropathic cystinosis (also called infantile), intermediate cystinosis (a juvenile form) and the third form, nonnephropathic cystinosis occurs exclusively in adults.. The children are born healthy and appear generally normal during the first months. Impaired kidney function eventually leads to severe kidney failure. Excessive urination and thirst commonly lead to evaluation and diagnosis. Kidney damage may result in the need for dialysis or kidney transplantation. The electrolyte balance is affected. The eyes and vision may be affected by storage of cystine crystals in the cornea and retina. Growth disorders are common as well as weak muscles. The function of the thyroid gland may be impaired (hypothyroidism) and puberty may be delayed and/or stop.. In non-nephropathic cystinosis the only symptoms are from the eyes. Today, cystinosis may be treated with medications (Cysteamine®, Cystagon). Treatment may also be required in the form of thyroid hormones, ...
This study examined the effect of glutathione on the in vivo depigmenting potency of N-acetyl-4-S-cysteaminylphenol (N-acetyl-4-S-CAP) in black and yellow mice after multiple intraperitoneal injections on 10 consecutive days. In black mice (C57BL/6J, a/a), N-acetyl-4-S-CAP showed dose-dependent depigmenting potency (0.5, 1.0, and 2.0 mmol/kg), which was in parallel to the tissue eumelanin content (98%, 28%, and 3% of controls, respectively) and to the tissue glutathione content (94%, 85%, and 76%, respectively). In lethal yellow mice (C57BL/6J, Ay/a), only a dose of 2.0 mmol/kg showed the color change of hair to dark, not to white as seen in black mice. This was reflected by the decrease of pheomelanin content (56%) and the increase of eumelanin content (28% of black mice). The simultaneous administration of N-acetyl-cysteine, which up-regulated glutathione content, completely abolished the depigmenting potency of N-acetyl-4-S-CAP, whereas administration of buthionine sulfoximine, which depleted ...

We have investigated the effects of cystamine on the replication of human immunodeficiency virus (HIV) in human lymphocytes and macrophages, the natural targets of HIV in vivo. Treatment of chronically infected macrophages with cystamine, at a concentration (500 microM) that did not show any cytotoxic or cytostatic effects, strongly decreased (, 80%) HIV-p24 antigen production and completely abolished the production of infectious viral particles. Cystamine does not affect viral transcription, translation or protein processing; indeed, all HIV proteins are present in a pattern similar to that of nontreated cells. Instead, cystamine interferes with the orderly assembly of HIV virions, as shown by electron microscopy analysis, that reveals only defective viral particles in treated cells. Moreover, suppression of HIV replication, due to the inhibition of proviral DNA formation was observed in acutely infected lymphocytes and macrophages pretreated with cystamine. These results show that cystamine ...

Thanks for sharing this wonderfully humorous article with us, Tom. I havent laughed so much for a good while.. Among the other… well, idiosyncratic ideas that the author has to offer is the apparently sincere belief that a safe diet must strictly limit fat, carbohydrate and protein.

"As a result of the high-fat nature of many kinds of cheese, eating cheese regularly can significantly contribute to obesity and thus to cardiovascular issues".. "…cheese can be a complete diet-wrecker because it is commonly paired with other carbohydrate-rich foods"..

ABSTRACT: Human cystinotic fibroblasts were completely depleted of their accumulated intracellular free cystine within a 2-h time interval when exposed to culture medium containing between 1 and 5 mM mercaptoethylgluconamide. This cystine-depleting action of mercaptoethylgluconamide was observed with three different human cystinotic fibroblast cell lines and with all three cell lines, 2 mM mercaptoethylgluconamide was as effective as 1 mM cysteamine in depleting cells of their intracellular free cystine. Cell viability was excellent for cystinotic fibroblasts exposed to 2 mM mercaptoethylgluconamide for up to 6 days in duration. Mercaptoethylgluconamide (2 mM) was sufficiently stable under cell culture conditions such that a single addition of mercaptoethylgluconamide maintained cystine depletion in human cystinotic fibroblasts for at least a 4-day period. In contrast to cysteamine, 2 mM mercaptoethylgluconamide was not capable of depleting the cystine content of isolated cystinotic lysosomes, implying
Scientists studying the rare and deadly genetic disease cystinosis, have shown that transplantation of adult bone marrow stem cells appears to virtually halt the disease in a mouse model. Cystine is a byproduct of the lysosomal breakdown of cellular components the body no longer needs. Normally, cystine is shunted out of cells, but in cystinosis a gene defect of the lysosomal cystine transporter causes cystine to build up, forming crystals that are especially damaging to the kidneys and eyes. The only available drug to treat cystinosis, cysteamine, while slowing the progression of kidney degradation, does not prevent it, and end-stage kidney failure is inevitable. "Cysteamine must be given every six hours, so children have to be woken up each night to take this drug, which has unpleasant side effects, and many others to treat various symptoms," said Dr. Stephanie Cherqui, the senior author of the study. "So although there is treatment, it is difficult treatment that does not cure the disease." ...
For improved mind health, there can hardly be of any alternative than DMAE bitartrate. The reduction in the build-up of the age pigment is one of the notable effects of DMAE bitartrate. Many anti-aging creams and lotions now contain this compound. The harmful effects of oxidation of cells can be done away with DMAE. The methyl group binds to the cell site and prevents it from getting oxidised.. However, a bit of precaution cannot go amiss, especially if you are pregnant. Try not to engage in regretting yourself with this powder. Unborn infants might get affected. Overall, DMAE is for the betterment of your brains and mind. These days we need to be at the tips and toes for better performances. While that adds to the pressure of living, it usually is reduced by the addition of DMAE Bitartrate. Works are on related to Alzheimers disease treatment as well since the disease affects their memory in aged individuals..

19 impromidine analogous guanidines were synthetized by acid hydrolysis of the corresponding N-cyanoguanidines. The guanidines were tested on the isolated spontaneously beating guinea-pig atrium for histamine H2-receptor affinity. Lengthening the ethyl chain of cysteamine by one methylene group leads to partial agonists of decreased activity. Impromidine congeners containing a branched cimetidine side chain prove to be potent H2-agonists with maximal or near maximal response. Affinity ratios in favour of the (R)-configurated enantiomers are moderate but clearly significant. The interaction between the affinity contributing moiety and the complementary receptor area shows a lower degree of stereoselectivity than does the efficacy contributing (imidazole-4-yl)propyl substituent of impromidine and sopromidine, respectively. Homoisohistamine derivatives dramatically lose both efficacy and affinity. ...

Your childs doctor may diagnose a urinary tract infection based on physical examination and a description of symptoms. Other studies may include a urinalysis (a laboratory examination of urine for various cells and chemicals, such as red blood cells, white blood cells, infection, or excessive protein) and culture that will detect the presence of an infection.. A boy with a UTI or girls under age 5 or 6 may require further diagnostic testing with a renal ultrasound. This is a diagnostic imaging technique that uses high-frequency sound waves and a computer to create images of blood vessels, tissues, and organs. Ultrasounds are used to view internal organs as they function, and to assess blood flow through various vessels. A voiding cystourethrography (VCUG) may also be needed in some children to evaluate the bladder and urethra and to detect reflux (in which urine backs up to the kidneys instead of flowing out through the urethra). In some cases, your doctor may recommend an intravenous ...

To unravel autism, researchers are examining its clinical heterogeneity, "genetic risk architecture," and how it alters brain connections and function. One of the difficulties in approaching autism is that a variety of genetic mutations can result in autistic behaviors, and only a few of these mutations have been identified. Bear himself has been probing the single gene disorder, Fragile X syndrome (responsible for about 5% of the cases "of full"blown autism.") In Fragile X, the FMR1 gene is silenced, leading to a missing protein that serves as a key regulator of brain proteins involved in neuron communication. Without FMR1, "the brakes are missing," and theres excessive protein synthesis leading to altered brain function ...
Our journey with Lupus began in December of 1988. It was my freshman year at UW-Oshkosh. My toes were turning purple after walking to and from my classes.

Many tests were performed as many different things were happening at the same time: vasculitis (inflammation of the blood vessels) in my leg, pleurisy (inflammation of the tissue surrounding the lungs, which made it hard for me to breathe), and glomerulonephritis (inflammation of the membrane tissue in the kidneys which causes inefficient filtering and excessive protein in the urine). With medication and treatment, the vasculitis and the pleurisy subsided. My kidneys, however, were damaged. During these frustrating months of tests and hospital stays, my parents and family were by my side. My Mom insisted on finding the cause to all these symptoms. She asked the doctors if starting the birth control pill a month earlier had anything to do with what was ...

Well I was practicing the tips outlined... you know reality checks during the day, meaning I would act as if i was dreaming and would say ask my self am i dreaming and then would look at the back of my hand or look at writings on a wall or a tv. Also, I take 3 supplements to enhance... b-6, melatonin, and choline bitartrate. All about 45 minutes before i go to bed. Now how I recognized was that I was in the dream and something clicked to do a reality check. When I did something in my head made it seem like something was off but at the same time it wasnt as vivid but I knew It wasnt normal so I said let me try to fly and I did...unfortunatley I woke up after flying in circles twice.

The most common mutation in the nephropathic cystinosis (CTNS) gene is a homozygous 57-kb deletion that also includes an adjacent gene carbohydrate kinase-like (CARKL). The latter gene encodes a protein that is predicted to function as a carbohydrate kinase. Cystinosis patients with the common 57-kb deletion had strongly elevated urinary concentrations of sedoheptulose (28-451 mmol/mol creatinine; controls and other cystinosis patients ,9) and erythritol (234-1110 mmol/mol creatinine; controls and other cystinosis patients ,148). Enzyme studies performed on fibroblast homogenates derived from patients carrying the 57-kb deletion revealed 80% reduction in their sedoheptulose phosphorylating activity compared to cystinosis patients with other mutations and controls. This indicates that the CARKL-encoded protein, sedoheptulokinase (SHK), is responsible for the reaction: sedoheptulose + ATP --, sedoheptulose-7-phosphate + ADP and that deletion of CARKL causes urinary accumulation of sedoheptulose ...

Main Results:. Although testosterone levels were within normal limits in 7 of 10 patients with cystinosis, the mean testosterone level in patients with cystinosis was 11.5 2.0 nmol/L compared with 24.2 3.0 nmol/L in control patients (P , 0.005). No patient with cystinosis reached Tanner stage 5 (full pubertal development), whereas 9 of 11 control patients did. Seven of 10 patients with cystinosis had elevations in LH or follicle-stimulating hormone (FSH) levels, suggesting testicular failure. These patients also had normal LH and FSH responses after GnRH stimulation, increased LH pulse frequency, and reduced testosterone response after HCG stimulation. In comparison, only 3 of 11 control patients had minimally elevated gonadotropin levels, and all 11 had normal testosterone levels. Microscopic testicular examination in one patient showed cystine crystals, germinal dysplasia, increased fibrosis, and Leydig cell hyperplasia. ...
Systemic sclerosis (SSc) is an autoimmune disease characterized by fibrosis of the skin and visceral organs and vascular alterations. SSc pathophysiology involves systemic inflammation and oxidative stress. Because the vanin-1 gene (vnn1) encodes an enzyme with pantetheinase activity that converts vasculoprotective pantethine into profibrotic pantothenic acid and pro-oxidant cystamine, we tested this pathway in the pathophysiology of SSc. Activation of the vanin-1/pantetheinase pathway was investigated in wild-type BALB/c mice with hypochlorous acid (HOCl)-induced SSc by ELISA and Western blotting. We then evaluated the effects of the inactivation of vnn1 on the development of fibrosis, endothelial alterations, and immunological activation in mice with HOCl- and bleomycin-induced SSc. We then explored the vanin-1/pantetheinase pathway in a cohort of patients with SSc and in controls. In wild-type mice with HOCl-induced SSc, the vanin-1/pantetheinase pathway was dysregulated, with elevation of ...

It has been suggested that taurine, hypotaurine and their metabolic precursors (cysteic acid, cysteamine and cysteinesulphinic acid) might act as antioxidants in vivo. The rates of their reactions with the biologically important oxidants hydroxyl radical (.OH), superoxide radical (O2.-), hydrogen peroxide (H2O2) and hypochlorous acid (HOCl) were studied. Their ability to inhibit iron-ion-dependent formation of .OH from H2O2 by chelating iron ions was also tested. Taurine does not react rapidly with O2.-, H2O2 or .OH, and the product of its reaction with HOCl is still sufficiently oxidizing to inactivate alpha 1-antiproteinase. Thus it seems unlikely that taurine functions as an antioxidant in vivo. Cysteic acid is also poorly reactive to the above oxidizing species. By contrast, hypotaurine is an excellent scavenger of .OH and HOCl and can interfere with iron-ion-dependent formation of .OH, although no reaction with O2.- or H2O2 could be detected within the limits of our assay techniques. ...

Cystinosis has been classified as a lysosomal storage disorder on the basis of cytologic and other evidence pointing to the intralysosomal localization of stored cystine. Cystinosis differs from the other lysosomal diseases inasmuch as acid hydrolysis, the principal enzyme function of lysosomes, is not known to play a role in the metabolic disposition of cystine. The fact that plasma levels are well below saturation indicates that the defect is a cellular one. Within the cell, cystine is compartmentalized with acid phosphatase and is membrane-bound as demonstrated by electron microscopy. Ferritin accumulates in the same organelle which appears to be the lysosome. (219800) ...
Diatrizoate is the most commonly used water-soluble, iodinated, radiopaque x-ray contrast medium. Radiopaque agents are drugs used to help diagnose certain medical problems. They contain iodine, which blocks x-rays. Depending on how the radiopaque agent is given, it localizes or builds up in certain areas of the body. The resulting high level of iodine allows the x-rays to make a "picture" of the area. The areas of the body in which the radiopaque agent localizes will appear white on the x-ray film. This creates the needed distinction, or contrast, between one organ and other tissues. The contrast will help the doctor see any special conditions that may exist in that organ or part of the body ...
Potassium bitartrate can be mixed with an acidic liquid such as lemon juice or white vinegar to make a paste-like cleaning agent for metals such as brass, aluminum or copper, or with water for other cleaning applications such as removing light stains from porcelain.[3] This mixture is sometimes mistakenly made with vinegar and sodium bicarbonate (baking soda), which actually react to neutralize each other, creating carbon dioxide and a sodium acetate solution.. Cream of tartar was often used in traditional dyeing where the complexing action of the tartrate ions were used to adjust the solubility and hydrolysis of mordant salts such as tin chloride and alum.. Cream of tartar, when mixed into a paste with hydrogen peroxide, can be used to clean rust from some hand tools, notably hand files. The paste is applied and allowed to set for a few hours and then washed off with a baking soda/water solution. After another rinse with water and thorough drying, a thin application of oil will protect the file ...

Considerable debate has taken place over the safety and validity of increased protein intakes for both weight control and muscle synthesis. The advice to consume diets high in protein by some health professionals, media and popular diet books is given despite a lack of scientific data on the safety of increasing protein consumption. The key issues are the rate at which the gastrointestinal tract can absorb amino acids from dietary proteins (1.3 to 10 g/h) and the livers capacity to deaminate proteins and produce urea for excretion of excess nitrogen. The accepted level of protein requirement of 0.8g · kg−1 · d−1 is based on structural requirements and ignores the use of protein for energy metabolism. High protein diets on the other hand advocate excessive levels of protein intake on the order of 200 to 400 g/d, which can equate to levels of approximately 5 g · kg−1 · d−1, which may exceed the livers capacity to convert excess nitrogen to urea. Dangers of excessive protein, defined ...

Proteostasis, a portmanteau of the words protein and homeostasis, is the concept that there are competing and integrated biological pathways within cells that control the biogenesis, folding, trafficking and degradation of proteins present within and outside the cell. The concept of proteostasis maintenance is central to understanding the cause of diseases associated with excessive protein misfolding and degradation leading to loss-of-function phenotypes, as well as aggregation-associated degenerative disorders. Therefore, adapting proteostasis should enable the restoration of proteostasis once its loss leads to pathology. Cellular proteostasis is key to ensuring successful development, healthy aging, resistance to environmental stresses, and to minimize homeostasis perturbations by pathogens such as viruses. Mechanisms by which proteostasis is ensured include regulated protein translation, chaperone assisted protein folding and protein degradation pathways. Adjusting each of these mechanisms to ...
A common criticism of low-carbohydrate diets is the effect of excessive protein intake on bone health and renal function. Reddy et al.19 reported that protein intake of 164-170 g on a 6-week VLCKD increased net acid load, urinary calcium losses, and risk of kidney stones. An earlier review20 of several studies of high-protein diets demonstrated that increasing consumption of alkaline foods (i.e., fruits and vegetables) resulted in a significant decrease in net acid excretion and calciuria along with increased bone deposition. Carter et al.21 found no difference in bone turnover between subjects following a VLCKD and those on a control diet after 3 months. Recent research22 suggests that protein intake of 120 g/day does not adversely affect kidney health in people with normal renal function. There is some evidence that carbohydrate restriction coupled with moderate protein intake may even benefit people with kidney disease and diabetes.23. Because cardiovascular events and stroke are the primary ...

As a model for understanding how protein disulfide isomerase (PDI) catalyzes disulfide bond formation in proteins, its action on a 28-residue disordered peptide containing only two cysteine residues has been examined. Disulfide formation in the peptide using the chemical reaction with small molecule thiol/disulfide reagents, such as oxidized and reduced glutathione or cystamine and cysteamine, occurs in two steps, via two alternative intermediate mixed disulfides between the reagent and either peptide cysteine residue. All thiol/disulfide forms of the peptide could be trapped and quantified, so the rates of their interconversion could be measured. Catalytic amounts of PDI increased the rates of these reactions. All rate enhancements were independent of the concentration of the peptide, indicating that it bound to PDI with an apparent K-m of less than 3 mu M. In the presence of glutathione, PDI accelerated the formation of both single mixed disulfide species, plus their subsequent rearrangement ...

The effects of intracerebroventricular (i.c.v.) or intracarotid (i.a.) administration of amylin (AMY) on growth hormone (GH) release induced by GH-releasing hormone (GHRH) were examined in conscious male rats. Amylin (25 ng-5 micrograms/rat, i.c.v. or 10 micrograms/rat, i.a.) was administered 10 min before GHRH (2 micrograms/kg, i.a.). I.c.v. administration of AMY dose-dependently inhibited GH secretion induced by GHRH but when given peripherally, AMY did not modify the GH response to GHRH. Amylin (10(-8)-10(-6) M) had no direct effect on the rat anterior pituitary in vitro either alone or when incubated with GHRH. To characterize the mechanism(s) involved in vivo in the inhibition of GH by AMY, we examined, at first, the effects of AMY on GHRH-induced GH release in rats depleted of somatostatin by pretreatment (4 h before) with cysteamine (300 mg/kg s.c.). The inhibitory activity of AMY on GH secretion elicited by GHRH seems to be independent of hypothalamic somatostatin; in fact, AMY was still ...

  • Although plasma levels remained under the detection threshold, significant increases in cysteamine brain levels were detected with the 50 and 200 mg/kg doses in mice perfused 1 and 3 h following cystamine injection. (harvard.edu)
  • Taken together, these results strongly suggest that cysteamine is the neuroactive metabolite of cystamine and may further support its therapeutic use in neurodegenerative diseases, particularly in HD and PD. (harvard.edu)
  • Using an in situ cerebral perfusion technique, we determined that the brain transport coefficient (Clup) of cysteamine (259 μM) was 0.15 ± 0.02 μL/g/s and was increased up to 0.34 ± 0.07 μL/g/s when co-perfused in the presence of cysteine. (harvard.edu)
  • Combination therapy with cysteamine bitartrate and N-acetylcysteine was associated with delay of isoelectric EEG (average time to isoelectric EEG was 52 months compared with 36 months in previous publications), depletion of GRODs, and subjective benefits as reported by parents and physicians (less irritability, improved alertness).
