The eukaryotic transcription factor NF-kappa B plays a central role in the induced expression of human immunodeficiency virus type 1 and in many aspects of the genetic program mediating normal T-cell activation and growth. The nuclear activity of NF-kappa B is tightly regulated from the cytoplasmic compartment by an inhibitory subunit called I kappa B(More)
Sporadic self-compatibility, the occasional fruit formation after otherwise incompatible pollinations, has been observed in some S12-containing genotypes of Solanum chacoense but not in others. We have sequenced this S12 allele and analyzed its expression in four different genotypes. The S12-RNase levels were generally less abundant than those of other(More)
Human infection associated with a novel reassortant avian influenza H7N9 virus has recently been identified in China. A total of 132 confirmed cases and 39 deaths have been reported. Most patients presented with severe pneumonia and acute respiratory distress syndrome. Although the first epidemic has subsided, the presence of a natural reservoir and the(More)
The evolution of the ability to synthesize specialized metabolites is likely to have been key for survival and diversification of different plant species. Oats (Avena spp.) produce antimicrobial triterpenoids (avenacins) that protect against disease. The oat beta-amyrin synthase gene AsbAS1, which encodes the first committed enzyme in the avenacin(More)
Many plants synthesize antimicrobial secondary metabolites as part of their normal program of growth and development, often sequestering them in tissues where they may protect against microbial attack. These include glycosylated triterpenoids (saponins), natural products that are exploited by man for a variety of purposes including use as drugs(More)
Extraembryonic ectoderm-derived factors instruct the pluripotent epiblast cells to develop toward a restricted primordial germ cell (PGC) fate during murine gastrulation. Genes encoding Bmp4 of the Dpp class and Bmp8b of the 60A class are expressed in the extraembryonic ectoderm and targeted mutation of either results in severe defects in PGC formation. It(More)

From September 2014 to March 2015, 23 outbreaks of norovirus (NoV) acute gastroenteritis occurred in Jiangsu, China. Partial sequencing of the NoV capsid gene suggested that 16 of the 23 outbreaks were related to a new GII.17 variant. This variant was first detected in sporadic specimens in October 2014, and became predominant in February 2015. Analysis of(More)
Much less is known about the etiology of influenza-like illness in China. A continuous surveillance of 16 respiratory viruses was conducted from November 2010 to October 2011 of outpatients with influenza-like illness in Nanjing, China. The two largest general hospitals and a provincial virus laboratory in Nanjing participated in this study. Throat swabs(More)
Chronic hepatitis B therapy with nucleos(t)ide analogues, particularly tenofovir or adefovir, may affect renal function. To date, there has not been a head-to-head controlled study to assess estimated glomerular filtration rate (eGFR) fluctuations in nucleos(t)ide-treated CHB patients. We aimed to evaluate the long-term effects of nucleos(t)ide on eGFR in(More)
A highly sensitive one-step real-time RT-PCR method using a minor-groove-binding (MGB) probe was developed for detection and quantitation of severe febrile with thrombocytopenia syndrome virus (SFTSV). The assay could discriminate SFTSV infection from other related viral diseases in human with a minimum detection limit of 10 viral RNA copies/µl and was(More)
