BACKGROUND & AIMS In the Asia-Pacific region, perinatal transmission of the hepatitis B virus (HBV) is the primary cause of chronic hepatitis B infection. Despite the use of HBIG and HBV vaccination, HBV perinatal transmission (PT) occurs in 10-30% of infants born to highly viremic mothers. We evaluated the efficacy and safety of LTD use during late(More)
BACKGROUND & AIMS Telbivudine reduces hepatitis B virus (HBV) DNA and normalizes levels of alanine aminotransferase (ALT) in patients with chronic hepatitis B (CHB). We investigated its use in preventing vertical transmission. METHODS We performed an open-label, prospective study of 88 hepatitis B (HB) e antigen (HBeAg)-positive pregnant women with CHB,(More)
The A-class of the erythropoietin-producing hepatocellular carcinoma cell-derived (EphA) tyrosine kinase receptors and their ligands, the A-ephrins, play critical roles in the specification of topographic axon projection maps during development. In this study, the role of the EphA subfamily in callosal projections was investigated using transgenic mice(More)
West Nile virus (family Flaviviridae, genus Flavivirus, WNV) was first detected in the Tennessee Valley and in Alabama in August 2001. In summer 2002, intensive viral activity was seen, but in subsequent years, viral activity settled into an enzootic pattern. Here, we report an analysis of viral activity in the mosquito fauna in the Mid-South from 2002 (the(More)
The Eph family tyrosine kinase receptors and their ligands, ephrins, play key roles in a wide variety of physiological and pathological processes including tissue patterning, angiogenesis, bone development, carcinogenesis, axon guidance, and neural plasticity. However, the signaling mechanisms underlying these diverse functions of Eph receptors have not(More)
Uranotaenia sapphirina, Culex erraticus, and Cx. peccator were collected in an enzootic eastern equine encephalomyelitis (EEE) virus focus in central Alabama (Tuskegee National Forest) from 2001 to 2003 and analyzed for virus as well as host selection. EEE virus was detected in each species every year except 2003, when pools of Cx. peccator were negative.(More)
—In today's data centers, the round trip propagation delay is quite small. Therefore, switch buffer sizes are much larger than the Bandwidth Delay Product (BDP). Based on this observation, in this paper we introduce a new transport protocol which provides bandwidth Sharing by Allocating switch Buffer (SAB) for data centers. SAB sets the congestion windows(More)
Despite the availability of an effective vaccine, the hepatitis B virus (HBV) infection and its treatment remains one of the foremost public health problems in the world. The present study was performed in order to investigate the anti-HBV activity of lutein in vitro. The antiviral activity of lutein was examined by detecting the levels of HBsAg, HBeAg and(More)
The Mopan persimmon (Diospyros kaki L. cv. Mopan) is the major cultivar of astringent persimmon in northern China. This study investigates the radical scavenging activity against ABTS and DPPH radical, and the content of total and individual phenolics (catechin, epicatechin, epigallocatechin, chlorogenic acid, caffeic acid, and gallic acid) with apple,(More)
Basic leucine zipper (bZIP) protein Nrf2 is a key transcription factor mediating the antioxidant response. Under homeostatic conditions Nrf2 is anchored to cysteine-rich Keap1 and sequestered in the cytoplasm. When challenged with oxidative stress, Keap1 functions as a redox-sensitive switch and releases Nrf2. Subsequently, Nrf2 translocates into the cell(More)
