People with Rett syndrome (RTT) have breathing instability in addition to other neuropathological manifestations. The breathing disturbances contribute to the high incidence of unexplained death and abnormal brain development. However, the cellular mechanisms underlying the breathing abnormalities remain unclear. To test the hypothesis that the central(More)
OBJECTIVES To evaluate the relationship between metabolic syndrome (MetS) and annual prostate growth rates in Chinese patients of different age decades with benign prostatic hyperplasia (BPH). METHODS We retrospectively analyzed the clinical data obtained from 1,052 Chinese men with BPH. Overnight fasting venous blood specimens were collected and serum(More)
CO2 chemoreception may be related to modulation of inward rectifier K+ channels (Kir channels) in brainstem neurons. Kir4.1 is expressed predominantly in the brainstem and inhibited during hypercapnia. Although the homomeric Kir4.1 only responds to severe intracellular acidification, coexpression of Kir4.1 with Kir5.1 greatly enhances channel sensitivities(More)
BACKGROUND Radical cystectomy (RC) with pelvic lymph node dissection (PLND) is the standard treatment for muscle-invasive and high-risk non-muscle-invasive bladder cancer (BCa). Large series with long-term oncologic data after laparoscopic RC (LRC) are rare. OBJECTIVE To report oncologic outcomes of LRC for 171 cases with a median 3-yr follow-up. (More)
Rett syndrome caused by mutations in methyl-CpG-binding protein 2 (Mecp2) gene shows abnormalities in autonomic functions in which brain stem norepinephrinergic systems play an important role. Here we present systematic comparisons of intrinsic membrane properties of locus coeruleus (LC) neurons between Mecp2(-/Y) and wild-type (WT) mice. Whole cell current(More)
Kir1.1 channel regulates membrane potential and K+ secretion in renal tubular cells. This channel is gated by intracellular protons, in which a lysine residue (Lys80) plays a critical role. Mutation of the Lys80 to a methionine (K80M) disrupts pH-dependent channel gating. To understand how an individual subunit in a tetrameric channel is involved in(More)
PURPOSE A retrospective study was designed to evaluate clinical outcomes and sagittal alignment following single-level unilateral instrumented transforaminal lumbar interbody fusion (TLIF). METHODS From November 2008 to December 2010, a total of 139 patients, who suffered from single-level lumbar degenerative disease, were included in this study.(More)
ATP-sensitive K+ channels (KATP) couple intermediary metabolism to cellular activity, and may play a role in the autoregulation of vascular tones. Such a regulation requires cellular mechanisms for sensing O2, CO2, and pH. Our recent studies have shown that the pancreatic KATP isoform (Kir6.2/SUR1) is regulated by CO2/pH. To identify the vascular KATP(More)
Chronic hypoxia is the most common cause of secondary pulmonary hypertension, for which the mechanisms are still unclear. Recent studies implicated an important role for microRNAs (miRNAs) in hypoxia-mediated responses in various cellular processes, including cell apoptosis and proliferation. Therefore, we hypothesized that these regulatory molecules might(More)
PURPOSE Transoral resection of the odontoid has been accepted as a standard procedure to decompress the cervicomedullary junction during the past several decades. The endoscopic transnasal odontoidectomy is emerging as a feasible surgical alternative to conventional microscopic transoral approach. In this article, we describe several operative nuances and(More)
