Secretory diarrhea is the leading cause of infant death in developing countries and a major cause of morbidity in adults. The cystic fibrosis transmembrane conductance regulator (CFTR) protein is required for fluid secretion in the intestine and airways and, when defective, causes the lethal genetic disease cystic fibrosis. We screened 50,000 chemically(More)
Large-Scale Antenna Systems (LSAS) is a form of multi-user MIMO technology in which unprecedented numbers of antennas serve a significantly smaller number of autonomous terminals. We compare the two most prominent linear precoders, conjugate beamforming and zero-forcing, with respect to net spectral-efficiency and radiated energy-efficiency in a simplified(More)
BACKGROUND Cutaneous squamous-cell carcinomas and keratoacanthomas are common findings in patients treated with BRAF inhibitors. METHODS We performed a molecular analysis to identify oncogenic mutations (HRAS, KRAS, NRAS, CDKN2A, and TP53) in the lesions from patients treated with the BRAF inhibitor vemurafenib. An analysis of an independent validation(More)
This study was conducted to characterize the vertical distribution of bacterial and archaeal communities in the water and sediment of Lake Taihu, which underwent a change in trophic status from oligotrophic to hypertrophic in last half of the 20th century. The results revealed that the bacterial communities in different layers of sediment sample were very(More)
BACKGROUND Human leukocyte antigen DP (HLA-DP) locus has been reported to be associated with hepatitis B virus (HBV) infection in populations of Japan and Thailand. We aimed to examine whether the association can be replicated in Han Chinese populations. METHODOLOGY/PRINCIPAL FINDINGS Two HLA-DP variants rs2395309 and rs9277535 (the most strongly(More)
δ-opioid receptors (DORs) form heteromers with μ-opioid receptors (MORs) and negatively regulate MOR-mediated spinal analgesia. However, the underlying mechanism remains largely unclear. The present study shows that the activity of MORs can be enhanced by preventing MORs from DOR-mediated codegradation. Treatment with DOR-specific agonists led to(More)
BACKGROUND Since late 2003, highly pathogenic avian influenza (HPAI) outbreaks caused by infection with H5N1 virus has led to the deaths of millions of poultry and more than 10 thousands of wild birds, and as of 18-March 2008, at least 373 laboratory-confirmed human infections with 236 fatalities, have occurred. The unrestrained worldwide spread of this(More)
The BRAF(V600E) mutation is common in several human cancers, especially melanoma. RG7204 (PLX4032) is a small-molecule inhibitor of BRAF(V600E) kinase activity that is in phase II and phase III clinical testing. Here, we report a preclinical characterization of the antitumor activity of RG7204 using established in vitro and in vivo models of malignant(More)
OBJECTIVES To describe temporal trends in fetal "growth" and to examine the roles of sociodemographic, anthropometric, and other determinants. STUDY DESIGN Hospital-based cohort study of 61,437 nonmalformed singleton live births at 22 to 43 weeks' gestational age. Four main measures were examined: (1) birth weight, (2) birth weight-for-gestational-age Z(More)
The reliability issues, including 100k cycle's endurance and 2 hours high temperature storage (HTS: 150degC, 200degC and 250degC) of sub-90nm NAND flash cells, are studied. Furthermore, the trap generation models in endurance and interface trap recovery model in HTS are proposed. Endurance characteristics show that the interface trap and bulk trap(More)
