CONTEXT Although chronic Helicobacter pylori infection is associated with gastric cancer, the effect of H pylori treatment on prevention of gastric cancer development in chronic carriers is unknown. OBJECTIVE To determine whether treatment of H pylori infection reduces the incidence of gastric cancer. DESIGN, SETTING, AND PARTICIPANTS Prospective,(More)
In Drosophila, the secreted BMP-binding protein Short gastrulation (Sog) inhibits signaling by sequestering BMPs from receptors, but enhances signaling by transporting BMPs through tissues. We show that Crossveinless 2 (Cv-2) is also a secreted BMP-binding protein that enhances or inhibits BMP signaling. Unlike Sog, however, Cv-2 does not promote signaling(More)
Diffuse large B-cell lymphoma (DLBCL) is a heterogeneous disease characterized by variable clinical outcomes. Outcome prediction at the time of diagnosis is of paramount importance. Previously, we constructed a 6-gene model for outcome prediction of DLBCL patients treated with anthracycline-based chemotherapies. However, the standard therapy has evolved(More)
BACKGROUND & AIMS Trials of therapies for chronic hepatitis C have used detection of hepatitis C virus (HCV) at week 24 of follow-up (sustained virologic response [SVR] 24) as a primary end point. However, there is increasing evidence that most patients who have an SVR at earlier time points (such as SVR12) maintain it until week 24. Use of earlier time(More)
Postsynaptic striatal neurodegeneration occurs through unknown mechanisms, but it is linked to high extracellular levels of synaptic dopamine. Dopamine-mediated cytotoxicity of striatal neurons occurs through two distinct pathways: autoxidation and the D1 dopamine receptor-linked signaling pathway. Here we investigated the mitogen-activated protein kinase(More)
Understanding the genetic basis of local adaptation is challenging due to the subtle balance among conflicting evolutionary forces that are involved in its establishment and maintenance. One system with which to tease apart these difficulties is clines in adaptive characters. Here we analyzed genetic and phenotypic variation in bud set, a highly heritable(More)
INTRODUCTION Liver transplantation (LT) has been the treatment of choice for patients with hepatocellular carcinoma (HCC). This study was designed to summarize our experience in LT for HCC patients and establish a new set of criteria for patient selection and prognosis prediction. MATERIALS AND METHODS Data of 195 patients with HCC were retrospectively(More)
PURPOSE We conducted a prospective, randomized controlled study to investigate the advantages and disadvantages of ureteral stenting after ureteroscopic lithotripsy. MATERIALS AND METHODS A total of 60 patients who underwent ureteroscopic lithotripsy were equally randomized into a stented or a nonstented group. The inclusion criteria were stone 6 to 10(More)
Protein kinase D (PKD) is a novel family of serine/threonine kinases targeted by the second messenger diacylglycerol. It has been implicated in many important cellular processes and pathological conditions. However, further analysis of PKD in these processes is severely hampered by the lack of a PKD-specific inhibitor that can be readily applied to cells(More)
OBJECTIVE Percent fat is often considered the reference for establishing the magnitude of adipose tissue accumulation and the risk of excess adiposity. However, the increasing recognition of a strong link between central adiposity and metabolic disturbances led us to test whether waist circumference (WC) is more highly correlated with metabolic syndrome(More)
