Although the efficacy of racemate ketamine, a rapid onset and sustained antidepressant, for patients with treatment-resistant depression was a serendipitous finding, clinical use of ketamine is limited, due to psychotomimetic side effects and abuse liability. Behavioral and side-effect evaluation tests were applied to compare the two stereoisomers of(More)
Paclitaxel chemotherapy is limited by a long-lasting painful neuropathy that lacks an effective therapy. In this study, we tested the hypothesis that paclitaxel may release mast cell tryptase, which activates protease-activated receptor 2 (PAR2) and, subsequently, protein kinases A and C, resulting in mechanical and thermal (both heat and cold)(More)
Ketamine exerts fast acting, robust, and lasting antidepressant effects in a sub-anesthetic dose, however, the underlying mechanisms are still not fully elucidated. Recent studies have suggested that ketamine's antidepressant effects are probably attributed to the activation of α-amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors. The(More)
This study hypothesized that depressive experiences of the elderly could be aggravated by universal factors such as low social status, poor health, financial strain, and unhealthy lifestyle, as well as by factors specific to an indigenous socio-cultural environment (stressful family dynamics) of a given population. Three hundred and fifty Chinese subjects(More)
Electroconvulsive therapy has been commonly applied in the treatment of refractory depression, but its cognitive side effects are noticed and restrict its application. The molecular mechanisms underlying the side effects remain elusive, and there is no efficient prevention. By employing a recognized electroconvulsive shock (ECS) rat model, we found in the(More)
The present study used Western blots and Northern slot blots to determine changes in the level of expression of GABA(A) receptor subunits alpha(1), alpha(2), and alpha(3), in relation to the "critical period" in cat visual cortex. Levels of the GABA(A) alpha(1) subunit were lowest at 1 week, increased four-fold to a maximum at 10 weeks, and declined(More)
OBJECTIVE To develop and characterise an animal model of paralytic neuropathy after Campylobacter jejuni infection. Campylobacter infection precedes development of many cases of Guillain-Barré syndrome and is particularly associated with cases having prominent axonal degeneration. Understanding the pathogenesis of Guillain-Barré syndrome after C jejuni(More)
BACKGROUND Asparagine synthetase (ASNS) is associated with drug resistance in leukaemia, and the function of this enzyme in the context of hepatocellular carcinoma (HCC) is not clear. In this study, the relationship between ASNS expression and clinical outcomes after surgical resection was investigated, and the therapeutic value of ASNS was also evaluated.(More)
The Daya Bay Reactor Neutrino Experiment has measured a nonzero value for the neutrino mixing angle θ(13) with a significance of 5.2 standard deviations. Antineutrinos from six 2.9 GWth reactors were detected in six antineutrino detectors deployed in two near (flux-weighted baseline 470 m and 576 m) and one far (1648 m) underground experimental halls. With(More)
We used a number of receptor antagonists to determine which receptors mediate the effect of arginine vasopressin (AVP) and oxytocin (OT) on insulin release. We found that OT (10(-7) M) and AVP (10(-8) M) increased insulin release from the perfused rat pancreas with similar magnitude. The antagonist with potent V1b receptor-blocking activity, dP[Tyr(Me)2]AVP(More)
