The structure and function of acid proteases. V. Comparative studies on the specific inhibition of acid proteases by diazoacetyl-DL-norleucine methyl ester, 1,2-epoxy-3-(p-nitrophenoxy) propane and pepstatin. (1/206)

Comparative studies have been made on the effects of diazoacetyl-DL-norleucine methyl ester (DAN), 1,2-epoxy-3-(p-nitrophenoxy)propane (EPNP) and pepstatin on acid proteases, including those from Acrocylindrium sp., Aspergillus niger, Aspergillus saitoi, Mucor pusillus, Paecilomyces varioti, Rhizopus chinensis, and Trametes sanguinea, and also porcine pepsin [EC 3.4.23.1] and calf rennin [EC 3.4.23.4] for comparative purposes. These enzymes were rapidly inactivated at similar rates and in 1:1 stiochiometry by reaction with DAN in the presence of cupric ions. The pH profiles of inactivation of these enzymes were similar and had optima at pH 5.5 to 6. They were also inactivated at similar rates by reaction with EPNP, with concomitant incorporation of nearly 2 EPNP molecules per molecule of enzyme. The pH profiles of inactivation were again similar and maximal inactivation was observed at around pH 3 to 4. Some of the EPNP-inactivated enzymes were treated with DAN and shown still to retain reactivity toward DAN. All these enzymes were inhibited strongly by pepstatin, and the reactions of DAN and EPNP with them were also markedly inhibited by prior treatment with pepstatin. These results indicate that the active sites of these enzymes are quite similar and that they presumably have at least two essential carboxyl groups at the active site in common, one reactive with DAN in the presence of cupric ions and the other reactive with EPNP, as has already been demonstrated for porcine pepsin and calf rennin. Pepstatin appears to bind at least part of the active site of each enzyme in a simmilar manner.  (+info)

Biochemical and functional profile of a newly developed potent and isozyme-selective arginase inhibitor. (2/206)

An increase in arginase activity has been associated with the pathophysiology of a number of conditions, including an impairment in nonadrenergic and noncholinergic (NANC) nerve-mediated relaxation of the gastrointestinal smooth muscle. An arginase inhibitor may rectify this condition. We compared the effects of a newly designed arginase inhibitor, 2(S)-amino-6-boronohexanoic acid (ABH), with the currently available N(omega)-hydroxy-L-arginine (L-HO-Arg), on the NANC nerve-mediated internal anal sphincter (IAS) smooth-muscle relaxation and the arginase activity in the IAS and other tissues. Arginase caused an attenuation of the IAS smooth-muscle relaxations by NANC nerve stimulation that was restored by the arginase inhibitors. L-HO-Arg but not ABH caused dose-dependent and complete reversal of N(omega)-nitro-L-arginine-suppressed IAS relaxation that was similar to that seen with L-arginine. Both ABH and L-HO-Arg caused an augmentation of NANC nerve-mediated relaxation of the IAS. In the IAS, ABH was found to be approximately 250 times more potent than L-HO-Arg in inhibiting the arginase activity. L-HO-Arg was found to be 10 to 18 times more potent in inhibiting the arginase activity in the liver than in nonhepatic tissues. We conclude that arginase plays a significant role in the regulation of nitric oxide synthase-mediated NANC relaxation in the IAS. The advent of new and selective arginase inhibitors may play a significant role in the discrimination of arginase isozymes and have important pathophysiological and therapeutic implications in gastrointestinal motility disorders.  (+info)

Effect of gonadal steroids and gamma-aminobutyric acid on LH release and dopamine expression and activity in the zona incerta in rats. (3/206)

A dopaminergic system in the zona incerta stimulates LH release and may mediate the positive feedback effects of the gonadal steroids on LH release. In this study the mechanisms by which steroids might increase dopamine activity in the zona incerta were investigated. In addition, experiments were conducted to determine whether the inhibitory effects of gamma-aminobutyric acid (GABA) on LH release in the zona incerta are due to suppression of dopamine activity in this area or conversely whether the stimulatory effects of dopamine on LH release are due to suppression of a tonic inhibitory GABAergic system. Ovariectomized rats were treated s.c. with oil, 5 micrograms oestradiol benzoate or 5 micrograms oestradiol benzoate followed 48 h later by 0.5 mg progesterone, and killed 54 h after the oestradiol benzoate injection. At this time the LH concentrations were suppressed in the oestradiol benzoate group and increased in the group treated with oestradiol benzoate and progesterone. The ratio of tyrosine hydroxylase:beta-actin mRNA in the zona incerta was significantly increased by the oestradiol benzoate treatment, but the addition of progesterone resulted in values similar to those in the control group. At the same time, the progesterone treatment increased tyrosine hydroxylase activity in the zona incerta as indicated by an increase in L-dihydroxyphenylalanine (L-DOPA) accumulation after 100 mg 3-hydroxybenzylhydrazine hydrochloric acid (NSD1015) kg-1 and an increase in dopamine release as indicated by a increase in dihydroxyphenylacetic acid (DOPAC) concentrations (one of the major metabolites of dopamine). Ovariectomized rats treated with oestradiol benzoate plus progesterone were also injected i.p. with 75 mg gamma-acetylenic GABA kg-1 (a GABA transaminase inhibitor) to increase GABA concentrations in the brain. This treatment had no effect on the ratio of tyrosine hydroxylase:beta-actin mRNA but decreased L-DOPA accumulation and DOPAC concentrations in the zona incerta, indicating a post-translational inhibition of dopamine synthesis and release. Treatment of ovariectomized rats with oestradiol benzoate followed by 100 mg L-DOPA i.p. to increase dopamine concentrations in the whole brain had no effect on glutamic acid decarboxylase mRNA expression in the zona incerta, although it increased the glutamic acid decarboxylase:beta-actin mRNA ratio in other hypothalamic areas (that is, the medical preoptic area, ventromedial nucleus and arcuate nucleus). In conclusion, the steroids act to increase dopamine activity in different ways: oestrogen increases tyrosine hydroxylase mRNA expression and progesterone acts after translation to increase tyrosine hydroxylase activity and dopamine release (as indicated by increases in DOPAC concentrations). This latter effect may be due to progesterone removing a tonic GABAergic inhibition from the dopaminergic system.  (+info)

Studies on convulsants in the isolated frog spinal cord. I. Antagonism of amino acid responses. (4/206)

1. The isolated frog spinal cord was used to study the effects of picrotoxin, bicuculline, and strychnine on the responses of primary afferents to amino acids. Recording was by sucrose gap technique. 2. A series of neutral amino acids was found to depolarize primary afferents. Optimal activity was obtained by an amino acid whose carboxyl and amino groups were separated by a three-carbon chain length (i.e. GABA). Amino acids with shorter (i.e. beta-alanine, glycine) or longer (i.e. delta-aminovaleric acid, epsilon-aminocaproic acid) distances between the charged groups were less potent. Imidazoleacetic acid was the most potent depolarizing agent tested. 3. Picrotoxin and bicuculline antagonized the primary afferent depolarizations of a number of amino acids tested with equal specificity. Depolarizing responses to standard (10- minus 3 M) concentrations of beta-alanine and taurine were completely blocked by these convulsants, while depolarizations to 10- minus 3 gamma-aminobutyric acid (GABA) were only partially antagonized. Glycine responses were unaffected by these agentsk; Strychnine completely blocked beta-alanine and taurine depolarizations and incompletely antagonized several other neutral amino acids. GABA, glutamate, and glycine depolarizations were not affected. 5. These results suggest that there are at least three distinct populations of neutral amino acid receptors on primary afferent terminals: a GABA-like receptor, a taurine/beta-alanine receptor, and a glycine-like receptor. The strychnine resistance of the glycine responses indictaes that the primary afferent receptors for glycine differ from those on the somata of spinal neurones.  (+info)

Inhibition of the development of the cellular slime mould Dictyostelium discoideum by omega-aminocarboxylic acids. (5/206)

Four omega-aminocarboxylic acids - epsilon-aminocaproic acid (EACA), trans-4-aminomethylcyclohexane-1-carboxylic acid (t-AMCHA), p-aminomethylbenzoic acid (PAMBA) and omega-aminocaprylic acid (OACA) -- prevented fruiting body formation of the cellular slime mould Dictyostelium discoideum. At concentrations of 40 mM, 75 mM, 10 mM and 5 mM, respectively, they allowed aggregation but prevented all further development at 24 degrees C. At lower concentrations, EACA allowed fruiting body formation but with a reduced number of spores per fruiting body. Only t-AMCHA had a significant inhibitory effect on the growth of myxamoebae. EACA affected development only if it was present between 8 and 16 h after the cells were deposited on the filters. Its effect was enhanced by high salt concentrations and by higher temperature, and was also dependent on the manner in which the cells were grown. Only strains capable of axenic growth displayed this sensitivity to EACA, although strains carrying only one of the genetic markers for axenic growth (axe A) were partially sensitive.  (+info)

The effect of epsilon-aminocaproic acid on biochemical changes in the development of the cellular slime mould Dictyostelium discoideum. (6/206)

epsilon-Aminocaproic acid (EACA) inhibited the development of Dictyostelium discoideum strain AX2 after the aggregation stage. Biochemical changes that occurred early in development (loss of cellular protein, RNA and carbohydrate; increase in the specific activity of N-acetylglucosaminidase, alpha-mannosidase, threonine deaminase and leucine aminopeptidase) were not affected by concentrations of EACA which blocked development; but biochemical changes that occurred later (synthesis of carbohydrate, increase in the specific activity of UDP-glucose pyrophosphorylase) were inhibited. Spores from fruiting bodies formed in the presence of low concentrations of EACA were larger, more spherical and less able to survive heat treatment than spores from fruiting bodies of control (no EACA) cells.  (+info)

Inhibition of intravascular fibrin deposition by dipyridamole in experimental animals. (7/206)

Intravascular fibrin deposition was induced in rabbits by endotoxin, the infusion of fibrin monomer (FM), and by the infusion of thrombin and EACA. A previously developed radioisotope technique was used to measure the fibrin deposits in various organs. Dipyridamole treatment of rabbits caused significant inhibition of fibrin deposition in all three experimental models. The drug also inhibited platelet consumption and, in the thrombin- and EACA-infused animals, fibrinogen consumption as well. The results obtained with dipyridamole were compared with the effect of thorotrast. It was concluded from this comparison that the effect of dipyridamole could not be attributed to inhibition of the reticuloendothelial system. It is postulated that dipyridamole inhibits the final step at which soluble FM is precipitated as fibrin in vivo.  (+info)

Solubilization of Escherichia coli nitrate reductase by a membrane-bound protease. (8/206)

Nitrate reductase extracted from the membrane of Escherichia coli by alkaline heat treatment was purified to homogeneity and used to prepare specific antibody. Nitrate reductase, precipitated by this antibody from Triton extracts of the membrane, contained a third subunit not present in the purified enzyme used to prepare the antibody. Nitrate reductase precipitated by antibody from alkaline heat extracts was composed of peptide fragments of various sizes. These fragments were produced by a membrane-bound protease which was activated by alkaline pH and heat. It is the action of this protease that releases the enzyme from the membrane, as shown by the observations that protease inhibitors decreased the amount of solubilization of the enzyme, and the enzyme remaining in the membrane after heating showed much less proteolytic cleavage than that which was released.  (+info)

*Norvaline

... (abbreviated as Nva) is an amino acid with the formula CH3(CH2)2CH(NH2)CO2H. The compound is an isomer of the more common amino acid valine. Like most other α-amino acids, norvaline is chiral. It is a white, water-soluble solid. Norvaline is a non-proteinogenic unbranched-chain amino acid. It has previously been reported to be a natural component of an antifungal peptide of Bacillus subtilis. Norvaline and other modified unbranched chain amino acids have received attention because they appear to be incorporated in some recombinant proteins found in E. coli. Its biosynthesis has been examined. The incorporation of Nva into peptides reflects the imperfect selectivity of the associated aminoacyl-tRNA synthetase. In Miller-Urey experiments probing prebiotic synthesis of amino acids, norvaline, but also norleucine, are produced. Norvaline is known to promote tissue regeneration and muscle growth, and to become a precursor in the penicillin biosynthetic pathway. Norvaline and norleucine ...

Peripheral blood monocytes incubated in a serum-free medium degraded serum amyloid A (SAA) protein along three pathways. Of 20 normal subjects, 8 degraded SAA completely with no detectable intermediates. Eight subjects transiently produced an amyloid A (AA)-like intermediate which comigrated on sodium dodecyl sulfate-polyacrylamide gel electrophoresis (PAGE) with tissue AA protein and reacted with antisera to AA, whereas four subjects yielded a persistent AA-like intermediate on PAGE. This group also failed to degrade tissue AA protein. Cells from 10 patients with amyloidosis fell into the second group. The responsible enzymes appear to be serine proteases because they are inhibited by disopropyl fluorophosphate. They were not affected by epsilon-amino caproic acid, L-1-tosylamide-2-phenylethyl chloromethyl ketone, or N-alpha-p-tosyl-L-lysine chlormethyl ketone. It appears possible that the enzymes are associated with the outer membrane of the cell because only a small fraction of the activity ...

So, we now have to make a decision between two drugs. One drug is the ACTH steroid. ACTH is FDA approved (and covered by insurance), begins in the hospital, is an injection that must be given twice a day for 6 weeks, has serious, life threatening side effects (including decreased immune system) and has a 50% chance of working. Once treatment begins, well know within 2 weeks if it is working, and if it stops her seizures, she is done with the drug in 6 weeks and may never need it again, unless she has a relapse. The side effects are reversible. The other drug is called Vigabatrin (Sabril) which is not FDA approved and must be obtained in either Canada or Mexico. Vigabatrin comes in pill form, and does not have the severe side effects associated with ACTH (including the fact that it will not alter her immune system, and she does not need hospitalization.) Vigabatrin has been in use everywhere except the US for 10 years, and has not been approved by the FDA because there is a report that some ...

Plasmin is the effector protease of the fibrinolytic system, well known for its involvement in fibrin degradation and clot removal. However, plasmin is also recognized as a potent modulator of immunological processes by directly interacting with various cell types including leukocytes (monocytes, macrophages, and dendritic cells) and cells of the vasculature (endothelial cells, smooth muscle cells) as well as soluble factors of the immune system and components of the extracellular matrix. In fact, the removal of misfolded proteins and maintenance of tissue homeostasis seem to be major physiological functions of plasmin. However, a large body of evidence also suggests that excessive plasmin generation frequently contributes to the pathophysiology of acute and chronic inflammatory processes. Hence, one question arising from the broadening effects of plasmin in physiology is whether antifibrinolytic drugs (i.e., tranexamic acid, epsilon aminocaproic acid, or aprotinin) that target plasmin either directly

Comments: 78 Pages.. Nylon comprises a family of man-made substances that were first manufactured in 1935. Nylonases are biological enzymes that can break down nylon oligomers. Although the most prominent nylonases are within the family of enzymes classified as 6-aminohexanoate hydrolases, some enzymes not formally classified as 6-aminohexanoate hydrolases also have the ability to breakdown nylons, and so can also be classified as nylonases. Organisms that encode a nylonase enzyme do not necessarily have the ability to actually survive on a nylon substrate as their sole carbon source. Among the first documented organisms that did have this ability was the soil bacterium Arthrobacter KI72. It has long been thought that nylonase genes and proteins were essentially absent from the biosphere prior to 1935. This belief led to the widespread assumption that any nylonase gene observed in the present must have emerged since 1935. Several authors developed hypothetical models of how a specific nylonase ...

The post-operative outcomes of 1,343 patients undergoing CABG with or without concomitant valve surgery between 1996 and 2005, and who received aprotinin, were compared with those of 6,776 patients who received aminocaproic acid and 2,029 patients who received no antifibrinolytic therapy (43). The mortality rate in the aprotinin group was 6.4%, compared with 2.4% in the aminocaproic acid group, and 2.2% for the group receiving no antifibrinolytic agent; after risk adjustment, the hazard ratio for death of patients treated with aprotinin compared with patients receiving no antifibrinolytic therapy or patients receiving aminocaproic acid was found to be 1.32 (95% CI: 1.12 to 1.55, p = 0.003) and 1.27 (95% CI: 1.10 to 1.46, p = 0.004), respectively. Aprotinin use was also associated with a larger risk-adjusted increase in serum creatinine (p , 0.0001).. Another retrospective database study published simultaneously reported a relative risk of in-hospital death of 1.32 (95% CI: 1.08 to 1.63) in a ...

The purpose of this study was to develop a fibrin gel system capable of serving as a three dimensional scaffold for the chondrogenesis of rabbit bone marrow mesenchymal stem cells (BM-MSCs) and to examine the effect of two fibrinolytic inhibitors, aprotinin and aminohexanoic acid, on this system. Rabbit BM-MSCs were obtained from the tibias and femurs of New Zealand white rabbits. After chondrogenic potential of BM-MSCs was verified by pellet culture, 2 x 106 cells were pelleted and suspended in fibrinogen (80mg/ml) and then mixed with equal parts of thrombin (5 IU/ml). The specimen were then divided into four groups: aprotinin control (with aprotinin); aprotinin + transforming growth factor (TGF-beta) (with aprotinin and TGF-beta 1); amino control (with aminohexanoic acid); and amino+TGF-beta (with aminohexanoic acid and TGF- beta1). Each of these groups was further divided into three groups depending on the concentration of the inhibitor. Both of the aprotinin groups received 0.0875, 0.175, or 0.35

The new observational study of 3876 patients from 62 medical centers was conducted between November 11, 1996, and December 7, 2006. Survival rates were assessed at 6 weeks, 6 months, and annually for 5 years after CABG surgery. The results were rather alarming: During the five-year examination period, 223 deaths occurred among 1072 aprotinin-treated patients, equal to 20.8 percent of the group. That death rate was nearly two-thirds greater than that of control patients (12.7 percent). After controlling for various patient factors, the results showed that Trasylol patients faced a 48 percent greater risk of death within a five-year period than those not using any medication.. Patients treated with aminocaproic acid had a death rate of 15.8 percent and those treated with tranexamic acid patients had a death rate of 14.7 percent, meaning either of these two alternative therapies carries with it a significantly lower mortality risk than aprotinin. Significantly, the authors noted that ...
Research being published in the New England Journal of Medicine today concluded that use of Bayers Trasylol (aprontin), a standard treatment to limit blood loss during heart surgeries, were at an increased risk of kidney failure, heart attacks and strokes, compared with patients taking alternative drugs, aminocaproic acid and tranexamic acid, or no drugs at all.

The ability of human embryonic stem cells (hESCs) and their derivatives to differentiate and contribute to tissue repair has enormous potential to treat various debilitating diseases. However, improving the in vivo viability and function of the transplanted cells, a key determinant of translating cell-based therapies to the clinic, remains a daunting task. Here, we develop a hybrid biomaterial consisting of hyaluronic acid (HA) grafted with 6-aminocaproic acid moieties (HA-6ACA) to improve cell delivery and their subsequent in vivo function using skeletal muscle as a model system. Our findings show that the biomimetic material-assisted delivery of hESC-derived myogenic progenitor cells into cardiotoxin-injured skeletal muscles of NOD/SCID mice significantly promotes survival and engraftment of transplanted cells in a dose-dependent manner. The donor cells were found to contribute to the regeneration of damaged muscle fibers and to the satellite cell (muscle specific stem cells) compartment. Such ...

Glycine, sarcosine, or N,N-dimethylglycine exerts a synergistic effect upon gamma-vinyl GABA for the treatment of seizure disorders, in particular epilepsy.
The crystallographic structure of the plasminogen kringle 4-epsilon-aminocaproic acid (ACA) complex (K4-ACA) has been solved by molecular replacement rotation-translation methods utilizing the refined apo-K4 structure as a search model (Mulichak et al., 1991), and it has been refined to an R value of 0.148 at 2.25-A resolution. The K4-ACA structure consists of two interkringle residues, the kringle along with the ACA ligand, and 106 water molecules. The lysine-binding site has been confirmed to be a relatively open and shallow depression, lined by aromatic rings of Trp62, Phe64, and Trp72, which provide a highly nonpolar environment between doubly charged anionic and cationic centers formed by Asp55/Asp57 and Lys35/Arg71. A zwitterionic ACA ligand molecule is held by hydrogen-bonded ion pair interactions and van der Waals contacts between the charged centers. The lysine-binding site of apo-K4 and K4-ACA have been compared: the rms differences in main-chain and side-chain positions are 0.25 and ...

GABA Release. Cerebral cortical neurons in culture were pre-loaded with [3H]GABA (1 μM, 0.1 μCi) for 30 min in the presence of 10 μM vigabatrin to irreversibly inactivate GABA-transaminase, thereby blocking GABA metabolism (Drejer et al., 1987; Gram et al., 1988). Individual cultures (35-mm Petri dishes) were subsequently placed in a superfusion apparatus (Drejer et al., 1987) at 37°C equipped with peristaltic pumps, and the cells were superfused at a flow rate of 2 ml/min. Fractions from the outlet were collected every 30 s, and at the end of the experiments, radioactivity was determined in all fractions. During the superfusion, either 200 μM nonradioactive GABA or 200 μM EF1502 was added to the superfusion medium for 2 min. Results were expressed as counts per minute per fraction collected. It should be noted that since the baseline of the GABA release during the entire superfusion period was constant no major loss of intracellular [3H]GABA occurred during this period.. Animals.

Norvaline (abbreviated as Nva) is an amino acid with the formula CH3(CH2)2CH(NH2)CO2H. The compound is an isomer of the more common amino acid valine. Like most other α-amino acids, norvaline is chiral. It is a white, water-soluble solid. Norvaline is a non-proteinogenic unbranched-chain amino acid. It has previously been reported to be a natural component of an antifungal peptide of Bacillus subtilis. Norvaline and other modified unbranched chain amino acids have received attention because they appear to be incorporated in some recombinant proteins found in E. coli. Its biosynthesis has been examined. The incorporation of Nva into peptides reflects the imperfect selectivity of the associated aminoacyl-tRNA synthetase. In Miller-Urey experiments probing prebiotic synthesis of amino acids, norvaline, but also norleucine, are produced. Norvaline is known to promote tissue regeneration and muscle growth, and to become a precursor in the penicillin biosynthetic pathway. Norvaline and norleucine ...

A process for the conversion of carbohydrates from any of a number of sources into butanol and hexanol for fuel or chemical use is disclosed. The process includes conducting a homoacetogenic fermentation to produce an acetic acid intermediate which is chemically converted to ethanol. The ethanol and a remaining portion of the acetic acid intermediate are used as a substrate in an acidogenic fermentation to produce butyric and caproic acid intermediates which are then chemically converted to butanol and hexanol.

Disulfide-rich neurotoxins from venomous animals continue to provide compounds with therapeutic potential. Minimizing neurotoxins often results in removal of disulfide bridges or critical amino acids. To address this drug-design challenge, we explored the concept of disulfide-rich scaffolds consisting of isostere polymers and peptidic pharmacophores. Flexible spacers, such as amino-3-oxapentanoic or 6-aminohexanoic acids, were used to replace conformationally constrained parts of a three-disulfide-bridged conotoxin, SIIIA. The peptide-polymer hybrids, polytides, were designed based on cladistic identification of nonconserved loci in related peptides. After oxidative folding, the polytides appeared to be better inhibitors of sodium currents in dorsal root ganglia and sciatic nerves in mice. Moreover, the polytides appeared to be significantly more potent and longer-lasting analgesics in the inflammatory pain model in mice, when compared to SIIIA. The resulting polytides provide a promising ...

We are going to start a slow increase of Jenelles Lamictal from 10mg a day to 60 mg a day. Dr. Shields recommended adding a pill every 3 days (until we reach 12 pills a day - yes, you read that correctly!) but Ive decided to be extra cautious and will add a pill every 5th day. We initially had such a positive result on Lamictal (10 days seizure free) and she hasnt had any side effects so I feel if we are more cautious and conservative, all the better. After she is at 60mg a day, we are to give her 2 weeks, then call UCLA again to discuss weaning one of her other drugs (Topamax & Vigabatrin.) There was a new study published recently that says Lamictal has the best response and best developmental progress of any drug for Lennox Gastaut kids. Sounds encouraging, and as if we are on the right path! So, Jenelle got her first added pill last night with dinner - then she promptly turned into the "Party Queen of the Night" that she was when we initially started Lamictal. That insomnia effect is no ...
article{8dbcd382-933d-4ca5-9453-b9238b0812ee, abstract = {BACKGROUND: To investigate, in a rabbit model, the effect of two different doses of vigabatrin (VGB) on retinal function and morphology. METHODS: Twenty-nine rabbits of mixed strain were divided into two groups, receiving either high-dose (n = 15) or low-dose (n = 14) oral VGB treatment (cumulative dose 29.8 +/- 2.9 g and 14.2 +/- 0.6 g respectively). Ten rabbits receiving water served as control animals. The rabbits underwent three baseline ff-ERG measurements before initiation of VGB medication and two ff-ERG registrations during treatment, after 8 and 12-14 weeks respectively. At the end of the study, the expression of protein kinase C-alpha (PKC-alpha), gamma amino butyric acid (GABA) A receptors, vimentin, glial fibrillary acidic protein (GFAP) and peanut agglutinin (PNA) was examined in retinal sections from all rabbits. RESULTS: In animals of the high-dose group, the ff-ERG measurements revealed a significant decrease of isolated ...
Gabapentin was conceived as part of a drug discovery program to treat neurological diseases, including epilepsy, spasticity, multiple sclerosis, and other central nervous system (CNS) disorders. This program began in the early 1970s at the German company, Goedecke, A.G., in Freiburg, Germany, which was a part of Warner-Lambert (now incorporated into Pfizer). The history of this project included chemical attempts to inhibit g-amino-butyric acid (GABA) degradation in brain with compounds that inhibited the catalytic pyridoxylphosphate of GABA-transaminase. It had already been known for some time that GABA was a key inhibitory neurotransmitter, and that experimental chemical impairment of GABA systems could cause seizures in experimental animals. The GABA transaminase project at Goedecke had progressed a compound to phase I clinical trials, but these were halted because of safety concerns. The chemical matter developed within the GABA transaminase project had no direct relationship to the chemical ...
The influence of the presence and position of a single beta-alanine, gamma-aminobutyric acid, epsilon-aminocaproic acid or 4-aminomethylbenzoic acid residue on the tendency to form b(n)+ -and y(n)+ -type product ions was determined using a group of protonated tetrapeptides with general sequence XAAG, AXAG and AAXG (where X refers to the position of amino acid substitution). The hypothesis tested was that the alternative amino acids would influence product ion signal intensities by inhibiting or suppressing either the nucleophilic attack or key proton transfer steps by forcing the adoption of large cyclic intermediates or blocking cyclization altogether. We found that specific b ions are diminished or eliminated completely when betaA, gammaAbu, Cap or 4AMBz residues are positioned such that they should interfere with the intramolecular nucleophilic attack step. In addition, differences in the relative proton affinities of the alternative amino acids influence the competition between ...

Vigabatrin is considered the drug of choice for infantile spasms and simple and complex partial epilepsy in childhood. Its mechanism of action relies on the irreversible inhibition of gamma-aminobutyric acid (GABA) transaminase. Since June 1997 several articles have been published reporting visual field constriction in adult patients on vigabatrin therapy. Recently, 7 pediatric patients, 1 on vigabatrin monotherapy and 6 on add-on therapy with visual field constriction have been described. We have observed 30 pediatric patients with epilepsy (14 boys and 16 girls), ages ranging from 4 to 20 years (mean: 11 years and 2 months) treated with vigabatrin for infantile spasms, simple and complex partial epilepsy, who had never complained of ophthalmologic disturbances. Twenty-one patients underwent complete routine ophthalmologic examination (fundus oculi, visual acuity, intraocular pressure, and visual field tests); 9 children (, 6 years old) underwent only fundus examination, because collaboration ...
Some children with a mild form of VWD do not need ongoing treatment; they may only need help after a medical procedure, including dental work, or after an accident that causes bleeding. Others may need to take medications.. One common drug used to treat VWD is desmopressin, a hormone that causes the body to release more von Willebrand factor and factor VIII into the bloodstream. Another treatment is von Willebrand factor replacement therapy, which infuses von Willebrand factor and factor VIII into the body intravenously. Certain antifibrinolytic drugs-medicines that prevent blood clots from being destroyed-may also be prescribed. Aminocaproic acid and tranexamic are two examples of these drugs.. If your child has a more serious form of VWD in which heavy bleeding is more likely, educate all caretakers, from teachers to sports coaches and the school nurse, about the disease and needed treatment in the event of an emergency.. ...
The effect of dopamine (DA)-mimetic drugs on the turnover rate of gamma-aminobutyric acid (GABA) in the superficial and deep layers of superior colliculus (SC) was studied. As an index of GABA turnover, the rate of accumulation of GABA was measured after irreversible inhibition of GABA-transaminase by gamma-vinyl-GABA, microinjected directly into SC. The rate of GABA accumulation in the deep layers of SC decreased by 30 to 45% after systemic administration of apomorphine, amphetamine and cocaine. This effect of DA agonists was prevented by pretreatment with haloperidol. A similar decrease in the rate of GABA accumulation in the deep layers of SC was observed after microinjection of the GABA agonist, muscimol (0.4 nmol) directly into the substantia nigra. Nigral microinjection of the GABA antagonist bicuculline (1.0 nmol), which per se did not affect GABA accumulation in SC, antagonized the effect of apomorphine on GABA accumulation in the deep layers of SC. The results indicate that the ...

Let me tell you something. The treatment for infantile spasms -- the disease that I looked up in that paperback book twenty years ago -- is almost exactly the same today as it was then. The first-line treatment is ACTH, a steroid injected intra-muscularly twice a day that wreaks havoc on the immune system, and in our case, caused Sophie to scream 22 out of 24 hours and to develop such a bad case of thrush (yeast growth all over and inside her mouth and genitals) that we had to discontinue it. Oh, and it didnt stop her seizures, so we began adding drugs (8 of them, before she was a year old). I assume the side effects of ACTH are the same now as they were then and understand that one tiny vial of the shit costs upwards of $28,000. In addition to steroids, babies diagnosed with infantile spasms are also now prescribed Vigabatrin, a drug that we tried back in the dark ages of the last millenium when it was non-FDA approved. Currently, if you embark on the Vigabatrin path at any point in your ...

Imidazole dipeptides derive their name from the imidazole ring of histidine. Carnosine (beta alanine histidine) is found in skeletal muscles and the brain, where it may be a neurotransmitter. It is hydrolyzed by two isozymes. Cytosolic carnosinase displays a very broad dipeptidase activity but does not hydrolyze anserine or homocarnosine. Serum carnosinase, also found in the cerebrospinal fluid, hydrolyzes carnosine and anserine but hydrolyzes homocarnosine very poorly. Anserine (beta alanine-1-methylhistidine) is normally absent from human tissues and body fluids but may be derived from the diet and is found in patients with serum carnosinase deficiency. Homocarnosine (gamma aminobutyryl histidine) is a brain dipeptide. It is hydrolyzed by serum but not by cytosolic carnosinase. The ...

Abstract Bilateral total knee arthroplasty (BTKA) patients may require blood transfusion which has its risks. Anti-fibrinolytic drugs such as aprotinin, aminocaproic acid and tranexamic acid (TXA) have reduced transfusion requirements in major surgery. This retrospective audit was performed to assess effectiveness of TXA in reducing blood transfusion rate in single-stage sequential BTKA cases operated by a single surgeon. Records of 91 patients given TXA and 80 controls who were operated before 2012 and not given TXA were reviewed. TXA was given 15mg/kg intravenously (IV) before tourniquet deflation and 3 hours postoperatively.Blood transfusion was done in 9(10%) patients in the TXA group compared to 20(25%)in the control group (p|0.01). One (1.25%) patient in the control group had non-fatal pulmonary embolism.TXA appeared to be effective in decreasing post-operative blood loss and requirement for blood transfusion after single-stage BTKA.
Selected phenolic acids are determined by capillary zone electrophoresis and HPLC, each using UV detection. The optimised CZE background electrolyte contained 50 mM acetic acid, 95 mM 6-aminocaproic acid, 0.1% polyacrylamide, 1% polyvinylpyrrolidone, and 10% methanol. Twelve phenolic acids (gallic, p-hydroxybenzoic, 3,4-dihydroxybenzoic, vanillic, syringic, o-coumaric, p-coumaric, caffeic, sinapic, ferulic, salicylic and chlorogenic) were separated within 10 minutes. Chromatographic separation of these phenolic acids was carried out on an Eclipse XBD C8 column using a mobile phase gradient (acetonitrile / methanol / water / 0.1% phosphoric acid); all were separated within 25 minutes. Electrophoretic and chromatographic determinations of ferulic and chlorogenic acids were compared on barley, malt, and potato samples. The methods characteristics were: linearity (1-20 mg ml and 0.2-4 mg ml−1), accuracy (recovery 94 ± 5% and 96 ± 4%), intra-assay repeatability (4.1% and 3.5%), and detection ...

TY - JOUR. T1 - Biorelevant polyanions stabilize fibrin against mechanical and proteolytic decomposition. T2 - Effects of polymer size and electric charge. AU - Komorowicz, Erzsébet. AU - Balázs, Nóra. AU - Tanka-Salamon, Anna. AU - Varga, Z.. AU - Szabó, László. AU - Bóta, A.. AU - Longstaff, Colin. AU - Kolev, K.. PY - 2020/2/1. Y1 - 2020/2/1. N2 - The release of neutrophil extracellular traps (NETs) containing DNA and histones is an essential mechanism in the neutrophil-mediated innate immunity. In thrombi the polyanionic DNA confers mechanical and lytic resistance to fibrin and heparins interfere with the effects of NET components. Heparins are polyanions used not only as therapeutic agents, but they are also released by mast cells at entry sites of pathogens. Platelets and microorganisms release a different type of polyanions (polyphosphates) of various size (in the range 60-1000 phosphate monomers). With the current study we aimed to evaluate if the stability of fibrin is influenced ...
