D-cycloserine increases positive symptoms in chronic schizophrenic patients when administered in addition to antipsychotics: a double-blind, parallel, placebo-controlled study. (1/293)

A hypofunction of the glutamatergic system and NMDA receptors in schizophrenia has been hypothesized. Therefore, stimulation of these receptors could be of benefit to patients with schizophrenia. D-cycloserine has been used for this purpose. This study reports the effects of 100 mg D-cycloserine, when added to typical antipsychotics in chronic schizophrenic patients exhibiting prominent negative symptoms, using a placebo-controlled, double-blind, parallel, design. D-cycloserine slightly worsened psychotic symptoms and general psychopathology as compared to placebo. D-cycloserine failed to change negative symptoms and had no effect on extrapyramidal symptoms. The exacerbation of schizophrenic symptoms may be explained by the antagonistic effects of this dose of D-cycloserine at the glycine recognition site of the NMDA receptor due to competition with the endogenous agonist glycine. Another explanation for the increase in psychopathology may be an interaction with the effects of antipsychotics on NMDA mediated neurotransmission. Thus, D-cycloserine in this study did not ameliorate schizophrenic symptoms. However, the fact that they actually worsened suggests that NMDA systems may be involved in the pathogenesis of schizophrenia. Further placebo-controlled studies with lower dosages of D-cycloserine, preferably in drug-free patients, are necessary to evaluate if D-cycloserine is of use for the treatment of patients with schizophrenia.  (+info)

N-methyl-D-aspartate receptor agonists modulate homocysteine-induced developmental abnormalities. (2/293)

We showed previously that the induction of neural crest (NC) and neural tube (NT) defects is a general property of N-methyl-D-aspartate receptor (NMDAR) antagonists. Since homocysteine induces NC and NT defects and can also act as an NMDAR antagonist, we hypothesized that the mechanism of homocysteine-induced developmental defects is mediated by competitive inhibition of the NMDAR by homocysteine. If this hypothesis is correct, homocysteine-induced defects will be reduced by NMDAR agonists. To test the hypothesis, we treated chicken embryos during the process of neural tube closure with sufficient homocysteine thiolactone to induce NC and NT defects in approximately 40% of survivors or with homocysteine thiolactone in combination with each of a selected set of NMDAR agonists in 0. 05-5000 nmol doses. Glutamate site agonists selected were L-glutamate and N-methyl-D-aspartate. Glycine site agonists were glycine, D-cycloserine, and aminocyclopropane-carboxylic acid. Glycine was the most effective overall, reducing defects significantly at two different doses (each P>0.001). These results support the hypothesis that homocysteine may affect NC and NT development by its ability to inhibit the NMDAR. One potentially important consequence of this putative mechanism is that homocysteine may interact synergistically with other NMDAR antagonists to enhance its effect on development.  (+info)

Flavone acetic acid induces a G2/M cell cycle arrest in mammary carcinoma cells. (3/293)

Flavone acetic acid (FAA) is a synthetic flavonoid that demonstrated extraordinary anti-tumour properties in murine models but was not effective in clinical trials. In an effort to better understand the molecular mechanisms by which FAA asserts its tumouricidal activities, we have examined the effect of FAA on the cell cycle. We observed FAA-mediated G2/M cell cycle arrest in mammary carcinoma cells at a concentration previously demonstrated to have anti-tumour effects in rodent models. The cell cycle arrest was accompanied by an increase in the P34cdc2 (cdc2) cyclin-dependent kinase activity. Morphological cytogenetic analysis demonstrated a colcemid-like effect of FAA on cytokinesis by causing accumulation of condensed C-metaphases of a sustained mitotic block. The cell cycle effect was blocked by the antioxidants ADPC and ascorbate, the superoxide scavenger Tiron, and the sphingosine kinase inhibitor L-cycloserine, but not by inhibitors of nitric oxide synthase. Based on these data, we propose that FAA may induce cell cycle arrest by stimulating the activity of acidic sphingomyelinase leading to the generation of reactive oxygen species.  (+info)

Induction of beta-lactamase influences the course of development in Myxococcus xanthus. (4/293)

Myxococcus xanthus is a gram-negative bacterium that develops in response to starvation on a solid surface. The cells assemble into multicellular aggregates in which they differentiate from rod-shaped cells into spherical, environmentally resistant spores. Previously, we have shown that the induction of beta-lactamase is associated with starvation-independent sporulation in liquid culture (K. A. O'Connor and D. R. Zusman, Mol. Microbiol. 24:839-850, 1997). In this paper, we show that the chromosomally encoded beta-lactamase of M. xanthus is autogenously induced during development. The specific activity of the enzyme begins to increase during aggregation, before spores are detectable. The addition of inducers of beta-lactamase in M. xanthus, such as ampicillin, D-cycloserine, and phosphomycin, accelerates the onset of aggregation and sporulation in developing populations of cells. In addition, the exogenous induction of beta-lactamase allows M. xanthus to fruit on media containing concentrations of nutrients that are normally too high to support development. We propose that the induction of beta-lactamase is an integral step in the development of M. xanthus and that this induction is likely to play a role in aggregation and in the restructuring of peptidoglycan which occurs during the differentiation of spores. In support of this hypothesis, we show that exogenous induction of beta-lactamase can rescue aggregation and sporulation of certain mutants. Fruiting body spores from a rescued mutant are indistinguishable from wild-type fruiting body spores when examined by transmission electron microscopy. These results show that the signal transduction pathway leading to the induction of beta-lactamase plays an important role in aggregation and sporulation in M. xanthus.  (+info)

Beta-cyanoalanine synthase: purification and characterization. (5/293)

Beta-cyano-L-alanine synthase [L-cysteine hydrogen-sulfide-lyase (adding HCN), EC] was purified about 4000-fold from blue lupine seedlings. The enzyme was homoegeneous on gel electrophoresis and free of contamination by other pyridoxal-P-dependent lyases. The enzyme has a molecular weight of 52,000 and contains 1 mole of pyridoxal-P per mole of protein; its isoelectric point is situated at pH 4.7. Its absorption spectrum has two maxima, at 280 and 410 nm. L-Cysteine is the natural primary (amino acid) substrate; beta-chloro- and beta-thiocyano can serve (with considerably lower affinity) instead of cyanide as cosubstrates for cyanoalanine synthase. The synthase is refractory to DL-cycloserine and D-penicillamine, potent inhibitors of many pyridoxal-P-dependent enzymes. Cyanoalanine synthase catalyzes slow isotopic alpha-H exchange in cysteine and in end-product amino acids; the rates of alpha-H exchange in nonreacted (excess) cysteine are markedly increased in the presence of an adequate cosubstrate; no exchange is observed of H atoms in beta-position.  (+info)

A possible involvement of ion transporter in tumor necrosis factor alpha and cycloheximide-induced apoptosis of endothelial cells. (6/293)

We examined the tumor necrosis factor alpha (TNFalpha)-induced apoptosis of vascular endothelial cells from the standpoint of ion channels. Cultured vascular endothelial cells from bovine carotid artery were used. Apoptosis was determined by a propidium iodide assay. Treatment of the endothelial cells with TNFalpha and cycloheximide for 6 h induced nuclear fragmentation in a TNFalpha dose-dependent manner (1-10 ng/ml). Concomitant treatment of endothelial cells with TNFalpha at a dose of 10 ng/ml and cycloheximide at a dose of 10 microg/ml elicited endothelial cell apoptosis as high as 23.4+/-4.1% at 6 h after administration. However, 10 ng/ml TNFalpha alone elicited a little apoptosis at 6 h after its administration (% apoptosis=4.1+/-0.8%). Cycloheximide (10 microg/ml) did not induce apoptosis at all. Concomitant treatment of endothelial cells with 1 mmol/l of 4,4-diisothiocyanatostilbene-2,2-disulfonic acid, which is a chloride bicarbonate exchanger blocker, partially inhibited the TNFalpha and cycloheximide-induced endothelial cell apoptosis. On the other hand, endothelial cell apoptosis due to TNFalpha and cycloheximide was completely inhibited by benzyloxycarbonyl-Asp-CH2OC(O)-2,6-dichlorobenzene (50 micromol/l), an inhibitor of caspase. Moreover, pyrrolidine dithiocarbanate, an inhibitor of nuclear factor kappa B (NF-kappaB), also suppressed endothelial cell apoptosis induced by TNFalpha and cycloheximide completely. These findings suggest that the endothelial cell apoptosis induced by TNFalpha and cycloheximide is closely related to not only chloride ions, but also both NF-kappaB and caspase activation. That is to say, there is a possibility that chloride ions or bicarbonate (pH) may play an important role in signal transduction such as NF-kappaB and caspase activation in the apoptosis induced by TNFalpha and cycloheximide.  (+info)

Characterization of a Mycobacterium smegmatis mutant that is simultaneously resistant to D-cycloserine and vancomycin. (7/293)

A mutant of Mycobacterium smegmatis has been isolated that is simultaneously resistant to both D-cycloserine (D-CS) and vancomycin. Genetic complementation with a PBP4 homolog restores sensitivity to both drugs. Resistance to D-CS and vancomycin in this mutant is most likely due to a novel mechanism involving peptidoglycan assembly at the cell surface.  (+info)

Intracellular modulation of NMDA receptor function by antipsychotic drugs. (8/293)

The present study deals with the functional interaction of antipsychotic drugs and NMDA receptors. We show that both the conventional antipsychotic drug haloperidol and the atypical antipsychotic drug clozapine mediate gene expression via intracellular regulation of NMDA receptors, albeit to different extents. Data obtained in primary striatal culture demonstrate that the intraneuronal signal transduction pathway activated by haloperidol, the cAMP pathway, leads to phosphorylation of the NR1 subtype of the NMDA receptor at (897)Ser. Haloperidol treatment is likewise shown to increase (897)Ser-NR1 phosphorylation in rats in vivo. Mutation of (896)Ser and (897)Ser to alanine, which prevents phosphorylation at both sites, inhibits cAMP-mediated gene expression. We conclude that antipsychotic drugs have the ability to modulate NMDA receptor function by an intraneuronal signal transduction mechanism. This facilitation of NMDA activity is necessary for antipsychotic drug-mediated gene expression and may contribute to the therapeutic benefits as well as side effects of antipsychotic drug treatment.  (+info)

Previous posts reviewed the evidence for weak electrical current for reducing symptoms of opioid and alcohol withdrawal. This post is offered as a concise review of promising herbal and other natural product treatments of alcohol craving and withdrawal, narcotic withdrawal and benzodiazepine withdrawal.. Traditionally used herbal medicines may reduce alcohol craving, lessen alcohol consumption and reduce symptoms of withdrawal. Three herbs are used in Chinese medicine to diminish alcohol craving, lessen alcohol absorption through the gut, or reduce symptoms of withdrawal. Kudzu (Radix puerariae) has been used as a treatment of alcohol abuse and dependence in Chinese medicine for almost 2000 years. Animal studies suggest that Kudzu extract significantly reduces alcohol craving (Keung 1993). A recent placebo-controlled human study found that individuals who had the opportunity to binge ...
D-alanine:D-alanine ligase (DDl) is an essential enzyme in bacterial cell wall biosynthesis and an important target for developing new antibiotics. It catalyzes the formation of D-alanine:D-alanine dipeptide, sequentially by using one D-alanine and one ATP as substrates for the first-half reaction, and a second D-alanine substrate to complete the reaction. Some gain of function DDl mutants can use an alternate second substrate, causing resistance to vancomycin, one of the last lines of defense against life-threatening Gram-positive infections. Here, we report the crystal structure of Staphylococcus aureus DDl (StaDDl) and its cocrystal structures with 3-chloro-2,2-dimethyl-N-[4(trifluoromethyl)phenyl]propanamide (inhibitor 1) (Ki=4 microM against StaDDl) and with ADP, one of the reaction products, at resolutions of 2.0, 2.2, and 2.6 A, respectively. The overall structure of StaDDl can be divided into three distinct domains. The inhibitor binds to a hydrophobic pocket at the interface of the ...

REL606-derived strains are resistant to streptomycin and phage T6. If using D-cycloserine, minimal medium is necessary. For these experiments we generally use 12 selective plates and 3 count plates per test strain. This is sufficient for resolving differences in mutation rates on the order of 10-fold. For measuring differences in mutation rate that are only 2- to 3-fold, we generally scale this up to 48 selective plates and 12 count plates per test strain. Making accurate comparisons of mutation rates on this scale is difficult. When comparing two strains and looking for very small changes, fluctuation tests for all strains should be done at the same time to avoid any number of confounding factors such as subtle differences in media, how long plates are incubated, whether very small colonies are counted as mutants, etc. Freshly prepared antibiotic and phage stocks should always be used. ...

Preliminary animal research suggests that yohimbine hydrochloride, a selective competitive alpha2-adrenergic receptor antagonist, accelerates fear extinction and converts ineffective extinction regimens (long intertrial intervals) to effective ones. This randomized placebo controlled study examined the potential exposure enhancing effect of yohimbine hydrochloride in claustrophobic humans. Participants (71% undergraduate students and 29% community volunteers) displaying marked claustrophobic fear (n = 24) were treated with 2 1-h in vivo exposure sessions. Participants were randomly allocated to take 10.8 mg yohimbine hydrochloride (n = 12) or placebo (n = 12) prior to each exposure session. Outcome measures included peak fear during a behavioral avoidance task, the Claustrophobia Questionnaire, and the Claustrophobic Concerns Questionnaire. Results showed that both conditions improved significantly at post-treatment with no significant difference between groups. Consistent with prediction the ...

Posted by Steven J. Seay, Ph.D. in Medication, Obsessive-compulsive disorder (OCD) As someone who has long been enamored with basic science, I find it fascinating when classic medications are re-purposed in surprising ways. One of the newest examples of this is the use of D-cycloserine (also known as Seromycin) in the treatment of obsessive-compulsive disorder (OCD). Whats interesting about D-cycloserine is not so much what it is…but what it isnt: D-cycloserine is neither an SRRI nor any other type of antidepressant (e.g., Prozac). Its not an anti-anxiety medication (e.g., Xanax, Klonopin). Its not even an atypical antipsychotic (e.g., Abilify, Risperdal). If its not one of the above, then what is it? The answer might surprise you. Seromycin is actually an antibiotic that was originally developed to help fight off tuberculosis. Whats exciting about using an antibiotic to treat OCD is that its not subject to the same side effects as other medications (i.e., the SSRIs, anxiolytics, or ...
Each exposure session was divided into three phases of 40 min: (1) GSM Basic (non-DTX) mode with one slot active per basic frame and each 26th basic frame idle. (2) GSM Talk mode consisting of temporal changes between the non-DTX (average 10.8 s) and DTX (average 5.6 s) modes. (3) GSM Environment mode consisting of a GSM Talk signal further amplitude-modulated by a power control function statistically based on measurements performed by France Telecom [Wiart et al., 2000]. The peak (slot-averaged) SAR level for all three phases was the same, however, the resulting average SARs varied: 100% (GSM Basic), 70% (GSM Talk), and 26% (GSM Environment). The SAR values indicated above are those for GSM Basic. The SAR levels in the GSM study had to be decreased in three steps over time since the body weight increase of the rats was greater than predicted and the available power was insufficient to maintain 4 W/kg. So, the SAR (GSM Basic) averaged over the entire exposure period was only 3.7 W/kg for the ...

(3) GSM Environment mode consisting of a GSM Talk signal further amplitude-modulated by a power control function statistically based on measurements performed by France Telecom [Wiart et al., 2000]. The peak (slot-averaged) SAR level for all three phases was the same, however, the resulting average SARs varied: 100% (GSM Basic), 70% (GSM Talk), and 26% (GSM Environment). The SAR values indicated above are those for GSM Basic. The SAR levels in the GSM study had to be decreased in three steps over time since the body weight increase of the rats was greater than predicted and the available power was insufficient to maintain 4 W/kg. So, the SAR (GSM Basic) averaged over the entire exposure period was only 3.7 W/kg for the ...

A recent study, now published in the highly regarded scientific journal Nature Genetics, considerably expands the present body of knowledge concerning the genetic determinants of drug resistance in M. tuberculosis. In this study, new genetic mutations associated with important second-line drugs for multidrug resistant tuberculosis treatment regimens such as cycloserine, ethionamide and para-amino salicylic acid are described. Also, the study identifies novel interactions between drug resistance associated genes that may contribute to increased resistance levels and, also highlights the role of efflux pumps (membrane proteins specialized in molecular transport) in the development of drug resistance across this bacterial species.. Beyond the more comprehensive and deeper knowledge on M. tuberculosis resistance mechanisms conveyed by this new data, it will enable the inclusion of specific markers for drug resistance in new rapid molecular diagnosis tests, envisioning an increase in sensitivity and ...

The relative effect of short daily periods of reverse occlusion in promoting recovery from the physiological effect of monocular deprivation in kittens were examined with a view to identifying a neurophysiological basis for the visual improvement observed with minimum occlusion therapy in amblyopia. Kittens were monocularly deprived from near birth until 5 weeks of age, at which time they were reverse-sutured and housed in total darkness. Each kitten received a short period of visual exposure through its initially deprived eye each day for either a fixed number of days or for a constant total visual exposure spread over a different number of exposure sessions. Electrophysiological recordings from single cells in the visual cortex were made the day after the last visual exposure. Kittens that received daily periods of reverse occlusion as brief as 30 min for 20 days showed a substantial degree of reversal of cortical ocular dominance. Other experiments indicated that 20 hr of reverse occlusion ...
