    Article Title: Selenocysteine Formation by Enterococcus faecium ABMC-05 Follows a Mechanism That Is Not Dependent on Genes selA and selD but on Gene cysK
    Article Snippet: The OPA solution was prepared with 50 mg of O-phthaldehyde (OPA, Pickering Laboratories) dissolved in 4 mL of methanol, followed by the addition of 50 μL of β-mercaptoethanol and 500 μL of 0.4 mol/L borate buffer.

    Article Title: mGluR5 positive allosteric modulation prevents MK-801 induced increases in extracellular glutamate in the rat medial prefrontal cortex.
    Article Snippet: Potentiation of metabotropic glutamate receptor subtype 5 (mGluR5) function produces antipsychotic‐like and pro‐cognitive effects in animal models of schizophrenia and can reverse cognitive deficits induced by N‐methyl‐ D‐aspartate type glutamate receptor (NMDAR) antagonists.. However, it is currently unknown if mGluR5 positive allosteric modulators (PAMs) can modulate NMDAR antagonist‐induced alterations in extracellular glutamate levels in regions underlying these cognitive and behavioral effects, such as the medial prefrontal cortex (mPFC).. We therefore assessed the ability of the mGluR5 PAM, 3‐cyano‐N‐(1,3‐diphenyl‐1H‐pyrazol‐5‐yl) benzamide (CDPPB), to reduce elevated extracellular glutamate levels induced by the NMDAR antagonist, dizocilpine (MK‐801), in the mPFC.

    Article Snippet: Fumonisins are naturally occurring mycotoxins that contaminate food for human and animal consumption.. They have neurotoxic effects, but the mechanisms by which these toxins affect the nervous system are not fully known.. In the present study, male Wistar rats were fed between 21 and 63 days of age with diets that contained fumonisins B1+B2 at 0, 1, and 4 mg/ kg.
