  • The Impact of D-Cycloserine and Sarcosine on in Vivo Frontal Neural
    Yao et al. BMC Psychiatry (2019) 19:314 https://doi.org/10.1186/s12888-019-2306-1 RESEARCH ARTICLE Open Access The impact of D-cycloserine and sarcosine on in vivo frontal neural activity in a schizophrenia-like model Lulu Yao1, Zongliang Wang1, Di Deng1, Rongzhen Yan1, Jun Ju1 and Qiang Zhou1,2* Abstract Background: N-methyl-D-aspartate receptor (NMDAR) hypofunction has been proposed to underlie the pathogenesis of schizophrenia. Specifically, reduced function of NMDARs leads to altered balance between excitation and inhibition which further drives neural network malfunctions. Clinical studies suggested that NMDAR modulators (glycine, D-serine, D-cycloserine and glycine transporter inhibitors) may be beneficial in treating schizophrenia patients. Preclinical evidence also suggested that these NMDAR modulators may enhance synaptic NMDAR function and synaptic plasticity in brain slices. However, an important issue that has not been addressed is whether these NMDAR modulators modulate neural activity/spiking in vivo. Methods: By using in vivo calcium imaging and single unit recording, we tested the effect of D-cycloserine, sarcosine (glycine transporter 1 inhibitor) and glycine, on schizophrenia-like model mice. Results: In vivo neural activity is significantly higher in the schizophrenia-like model mice, compared to control mice. D-cycloserine and sarcosine showed no significant effect on neural activity in the schizophrenia-like model mice. Glycine induced a large reduction in movement in home cage and reduced in vivo brain activity in control mice which prevented further analysis of its effect in schizophrenia-like model mice. Conclusions: We conclude that there is no significant impact of the tested NMDAR modulators on neural spiking in the schizophrenia-like model mice.

  • Frequently Asked Questions on The
    Frequently asked questions on the WHO treatment guidelines for isoniazid-resistant tuberculosis Version: 24 April 2018 The advice in this document has been prepared by the Global TB Programme of the World Health Organization (WHO) and is to be read alongside the WHO treatment guidelines for isoniazid-resistant tuberculosis and its online annexes. See Further reading ​ ​ at end for additional resources. Who are the new WHO treatment guidelines for isoniazid-resistant tuberculosis intended for ? ​ ​ The WHO treatment guidelines for isoniazid-resistant tuberculosis are targeted at health care ​ professionals (doctors, nurses) and other staff involved in TB care in both low and high resource settings. The possibility of drug-resistant disease now needs to be entertained whenever treating TB patients. These guidelines provide technical detail which is helpful in making the best-informed decision in clinical practice and programme management. The answers to the frequently asked questions (FAQ) in this document intend to help implementers with common, practical issues that arise when adopting the new guidance. This document complements the WHO guidelines by elaborating further on certain aspects of ​ implementation that were beyond the scope of the guideline itself. What are the main recommendations of these new guidelines ? The new guidelines recommend that patients with confirmed isoniazid-resistant and rifampicin susceptible tuberculosis (abbreviated to Hr-TB) are treated for 6 months with a regimen composed of ​ ​ rifampicin (R), ethambutol (E), pyrazinamide (Z) and levofloxacin (Lfx). The exclusion of rifampicin resistance ahead of start of this regimen is critical. It is further recommended not to add streptomycin (S) or other injectable agents to the treatment regimen.

  • An Investigation of D-Cycloserine As a Memory Enhancer Sabine Wilhelm
    May 23, 2016 An investigation of D-cycloserine as a memory enhancer Sabine Wilhelm, Ph.D. 1. Background and Significance BDD is defined as a preoccupation with an imagined defect in appearance; if a slight physical anomaly is present, the concern is markedly excessive (American Psychiatric Association [APA], 1994). Preoccupations may focus on any body area but commonly involve the face or head, most often the skin, hair, or nose (Phillips et al., 1993). These preoccupations have an obsessional quality, in that they occur frequently and are usually difficult to resist or control (Phillips et al., 1998). Additionally, more than 90% of BDD patients perform repetitive, compulsive behaviors (Phillips et al., 1998), such as frequent mirror checking (Alliez & Robin, 1969), excessive grooming (Vallat aet al., 1971), and skin picking (Phillips & Taub, 1995). Accordingly, a core component of Cognitive-Behavioral treatment for BDD is exposure and response prevention (ERP). Exposure and response prevention involves asking patients to gradually expose themselves to situations that make them anxious (e.g. talking to a stranger, going to a party) while refraining from engaging in any rituals (e.g. excessive grooming or camouflaging) or safety behaviors (e.g. avoiding eye contact). Rituals and safety behaviors are thought to maintain the fear response because they prevent the sufferer from staying in contact with the stimulus long enough for his or her anxiety to extinguish. By exposing the patient to the feared situation while preventing the rituals and safety behaviors, the patient’s anxiety is allowed to naturally extinguish and he is able to acquire a sense of safety in the presence of the feared stimulus.
