Fascicular ventricle tachycardia (FVT) arising from the proximal aspect of left His-Purkinje system (HPS) has not been specially addressed. Current study was to investigate its clinical, electrocardiographic, and electrophysiological characteristics.
Nicotinic acetylcholine receptors are important regulators of smoking behavior and tobacco carcinogenesis. We studied the association of the CHRNB3-A6 variant rs13280604 in relation to esophageal squamous cell carcinoma (ESCC) in Chinese populations. Two independent case–control studies were conducted. The first case–control study, consisted of 866 ESCC patients and 1621 healthy...
This article discusses the horizontal distribution and dominant species of heteropods in the East China Sea. The ecological characteristics of heteropods and their adaptability to the environments were also considered. Oceanographic census was carried out in the East China Sea (23°30 ′∼33° N and 118°30′∼128° E) in four seasons from 1997 to 2000. It was found that the total...
The incompatible pathosystem between resistant cotton (Gossypium barbadense cv. 7124) and Verticillium dahliae strain V991 was used to study the cotton transcriptome changes after pathogen inoculation by RNA-Seq. Of 32 774 genes detected by mapping the tags to assembly cotton contigs, 3442 defence-responsive genes were identified. Gene cluster analyses and functional assignments...
Growing evidence has demonstrated that microRNAs (miRNAs) play an important role in regulating cellular radiosensitivity. This study aimed to explore the role of miRNAs in non-Hodgkin's lymphoma (NHL) radiosensitivity. Microarray was employed to compare the miRNA expression profiles in B cell lymphoma cell line Raji before and after a 2-Gy dose of radiation. A total of 20...
BACKGROUND Eutopic endometria with endometriosis (EMs) differ dramatically from normal endometria, physiologically and biochemically, yet the pathogenesis of EMs remains unclear. Cofilin-1 (CFL1), a critical modulator of the actin cystoskeleton, is associated with tumour progression, cell motility, cell adhesion, cell invasion and angiogenesis. Although eutopic endometria with...
Hypoxia is one of the most pervasive physiological stresses within tumors. Hypoxia signaling contributes to the aggressive tumor behaviors through promoting tumor cells to undergo the fundamental metabolism adaptation. A series of evidence indicates that this process is mainly mediated by hypoxia-inducible factor (HIF). However, key molecules involved in tumor hypoxia adaptation...
Cytokine or growth factor activated STAT3 undergoes multiple post-translational modifications, dimerization and translocation into nuclei, where it binds to serum-inducible element (SIE, ‘TTC(N3)GAA’)-bearing promoters to activate transcription. The STAT3 DNA binding domain (DBD, 320–494) mutation in hyper immunoglobulin E syndrome (HIES), called the HIES mutation (R382Q, R382W...
Diminished ovarian reserve (DOR) is a heterogeneous disorder causing infertility, characterized by a decreased number of oocytes, the genetic cause of which is still unknown.
Background The aim of our study was to compare the efficacy and safety of: 1) transarterial chemolipiodolization with gelatin sponge embolization vs chemolipiodolization without embolization, and 2) chemolipiodolization with triple chemotherapeutic agents vs epirubicin alone.
Neuron-restrictive silencer factor (NRSF), also known as repressor element-1 silencing transcription factor, is a transcriptional repressor that plays important roles in embryonic development and neurogenesis. Recent findings show that NRSF is upregulated after seizures activity however, the link between NRSF and epileptogenesis remains poorly understood. To investigate the role...
Insulin-like growth factor binding protein 2 (IGFBP-2) is a malignancy-associated protein measurable in tumors and blood. Increased IGFBP-2 is associated with shortened survival of advanced glioma patients. Thus, we examined plasma IGFBP-2 levels in glioma patients and healthy controls to evaluate its value as a plasma biomarker for glioma. Plasma IGFBP-2 levels in 196 patients...
Biliary tract cancers are rare but fatal malignancies, with increasing incidence in Shanghai, China. Gallstones, the primary risk factor for biliary tract cancer, typically result from oversaturation of cholesterol in bile. We examined the association of five variants in three lipid metabolism-related genes (CETP, ABCG8 and LRPAP1) and biliary tract cancers and stones in a...
To evaluate the efficacy of green tea polyphenols (GTPs) in modulating aflatoxin B1 (AFB1) biomarkers, a total of 352 serum samples and 352 urine samples collected from a 3 month chemoprevention trial with 500 mg GTPs, 1000 mg GTPs and a placebo were measured for AFB1–albumin adducts (AFB–AA), aflatoxin M1 (AFM1) and aflatoxin B1–mercapturic acid (AFB–NAC). Levels of AFB–AA at...
DNA damage is an important mechanism in carcinogenesis, so genes related to maintaining genomic integrity may influence papillary thyroid cancer (PTC) risk. Candidate gene studies targeting some of these genes have identified only a few polymorphisms associated with risk of PTC. Here, we expanded the scope of previous candidate studies by increasing the number and coverage of...
Background Dietary intake of genistein by patients with prostate cancer has been associated with decreased metastasis and mortality. Genistein blocks activation of p38 mitogen-activated protein kinase and thus inhibits matrix metalloproteinase-2 (MMP-2) expression and cell invasion in cultured cells and inhibits metastasis of human prostate cancer cells in mice. We investigated...
In this study, we identified five novel polymorphisms in the estrogen receptor beta (ERβ) gene in an African population. Interestingly, two of these variants are expected to change the amino acid sequence of the ERβ protein. These changes correspond to an isoleucine to valine substitution at amino acid position 3 (I3V) and a valine to glycine substitution at position 320 (V320G...
