Acquisition of the intestinal microbiota begins at birth, and a stable microbial community develops from a succession of key organisms. Disruption of the microbiota during maturation by low-dose antibiotic exposure can alter host metabolism and adiposity. We now show that low-dose penicillin (LDP), delivered from birth, induces metabolic alterations and(More)
For psoriasis, an idiopathic inflammatory disorder of the skin, the microbial biota has not been defined using cultivation-independent methods. We used broad-range 16S rDNA PCR for archaea and bacteria to examine the microbiota of normal and psoriatic skin. From 6 patients, 19 cutaneous samples (13 from diseased skin and 6 from normal skin) were obtained.(More)
To determine whether protein tyrosine kinase (PTK) modulates volume-sensitive chloride current (I(Cl.vol)) in human atrial myocytes and to identify the PTKs involved, we studied the effects of broad-spectrum and selective PTK inhibitors and the protein tyrosine phosphatase (PTP) inhibitor orthovanadate (VO(4)(-3)). I(Cl.vol) evoked by hyposmotic bath(More)
ATP-sensitive potassium (KATP) channels have the unique ability to adjust membrane excitability and functions in accordance with the metabolic status of the cell. Skeletal muscles are primary sites of activity-related energy consumption and have KATP channels expressed in very high density. Previously, we demonstrated that transgenic mice with skeletal(More)
OBJECTIVE Narcolepsy is caused by the loss of hypocretin/orexin neurons in the hypothalamus, which is likely the result of an autoimmune process. Recently, concern has been raised over reports of narcolepsy in northern Europe following H1N1 vaccination. METHODS The study is a retrospective analysis of narcolepsy onset in subjects diagnosed in Beijing,(More)
Most studies of the human microbiome have focused on westernized people with life-style practices that decrease microbial survival and transmission, or on traditional societies that are currently in transition to westernization. We characterize the fecal, oral, and skin bacterial microbiome and resistome of members of an isolated Yanomami Amerindian village(More)
The purpose of this meta-analysis was to investigate the correlation between serum homocysteine (Hcy) levels and the pathogenesis of cerebral infarction (CI). Relevant studies involving serum Hcy levels and the pathogenesis of CI were identified using electronic database search supplemented with manual search. The search result studies were screened in(More)
Myocardial cell death is initiated by excessive mitochondrial Ca(2+) entry causing Ca(2+) overload, mitochondrial permeability transition pore (mPTP) opening and dissipation of the mitochondrial inner membrane potential (ΔΨm). However, the signalling pathways that control mitochondrial Ca(2+) entry through the inner membrane mitochondrial Ca(2+) uniporter(More)
BACKGROUND Psoriasis is a common chronic inflammatory disease of the skin. We sought to characterize and compare the cutaneous microbiota of psoriatic lesions (lesion group), unaffected contralateral skin from psoriatic patients (unaffected group), and similar skin loci in matched healthy controls (control group) in order to discern patterns that govern(More)
Executive dysfunctions have been consistently demonstrated in patients with schizophrenia. This study aimed to investigate deficits in specific executive functioning components, namely working memory and inhibition, in schizophrenia. In study 1, a set of neurocognitive function tests was administered to 41 patients with schizophrenia and 25 healthy controls(More)
