The determination of gene-by-gene and gene-by-environment interactions has long been one of the greatest challenges in genetics. The traditional methods are typically inadequate because of the problem referred to as the "curse of dimensionality." Recent combinatorial approaches, such as the multifactor dimensionality reduction (MDR) method, the(More)
A cytotoxicity test protocol for single-wall nanotubes (SWNTs), multi-wall nanotubes (with diameters ranging from 10 to 20 nm, MWNT10), and fullerene (C60) was tested. Profound cytotoxicity of SWNTs was observed in alveolar macrophage (AM) after a 6-h exposure in vitro. The cytotoxicity increases by as high as approximately 35% when the dosage of SWNTs was(More)
Abundantly expressed in fetal tissues and adult muscle, the developmentally regulated H19 long noncoding RNA (lncRNA) has been implicated in human genetic disorders and cancer. However, how H19 acts to regulate gene function has remained enigmatic, despite the recent implication of its encoded miR-675 in limiting placental growth. We noted that vertebrate(More)
Candida albicans is a common microorganism in the intestine. However, invasive C. albicans infection has emerged as a life-threatening disease in recent years. The mortality rate of invasive candidiasis is high in critically ill hosts. C. albicans can switch from the yeast to the hyphal morphology, and take advantage of the impaired intestinal mucosal(More)
A microbial consortium, designated WCS-6, was established by successive subcultivation in the presence of rice straw under static conditions. The degradation efficiencies of WSC-6 for 0.5 g filter paper, cotton and rice straw after 3 days of cultivation were 99.0±0.7%, 76.9±1.5% and 81.3±0.8%, respectively as determined by gravimetrical methods. Nine(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)
We used conventional methods to investigate the mechanism by which Acidithiobacillus ferrooxidans colonizes a solid surface by assessing pili-mediated sliding, twitching motility, and adherence. A. ferrooxidans slided to form circular oxidized zones around each colony. This suggested that slide motility occurs through pili or flagella, though A.(More)
Transforming growth factor beta (TGF-beta) signaling pathways regulate a wide variety of cellular processes including cell proliferation, differentiation, extracellular matrix deposition, development, and apoptosis. TGF-beta type-I receptor (TbetaRI) is the major receptor that triggers several signaling events by activating downstream targets such as the(More)
A mesophilic lignocellulolytic microbial consortium BYND-5, established by successive subcultivation, was applied to enhance the biogas production. The degradation efficiency of BYND-5 for rice straw was more than 49.0 ± 1.8% after 7 days of cultivation at 30°C. Various organic compounds, including acetic acid, propionic acid, butyric acid and glycerin were(More)
BACKGROUND The transmission of hemorrhagic fever with renal syndrome (HFRS) is influenced by climatic variables. However, few studies have examined the quantitative relationship between climate variation and HFRS transmission. OBJECTIVE We examined the potential impact of climate variability on HFRS transmission and developed climate-based forecasting(More)
