Particulate air pollution has been suggested as the cause of the recently observed decreasing trends of 10 to 25% in the ratio between hilly and upwind lowland precipitation, downwind of urban and industrial areas. We quantified the dependence of this ratio of the orographic-precipitation enhancement factor on the amounts of aerosols composed mostly of(More)
In obesity, accumulation of lipid in nonadipose tissues, or lipotoxicity, is associated with endoplasmic reticulum (ER) stress, mitochondrial dysfunction, and ultimately apoptosis. We have previously shown that obese women have increased triglycerides in follicular fluid; thus, the present study examined whether high-fat diet-induced obesity causes(More)
Halophytes have a distinct signaling pathway and regulatory network to impart salt stress tolerance. Environmental signals are first perceived by specific receptors, which modulate expression and activation of different genes leading to stress tolerance. SlASR, an abscisic acid-, stress-, and ripening-induced protein, was previously isolated and(More)
— Technologies for fabricating silicone rubber membranes and integrating them with other processes on silicon wafers have been developed. Silicone rubber has been found to have exceptional mechanical properties including low mod-ulus, high elongation, and good sealing. Thermopneumatically actuated, normally open, silicone rubber membrane valves with(More)
Sl NAC1 functions as a stress-responsive NAC protein involved in the abscisic acid-dependent signaling pathway and enhances transgenic Arabidopsis drought, salt, and cold stress tolerance. NAC (NAM, ATAF1, 2, CUC2) transcription factors constitute the largest families of plant-specific transcription factors, known to be involved in various growth or(More)
Hematologic spread of carcinoma results in incurable metastasis; yet, the basic characteristics and travel mechanisms of cancer cells in the bloodstream are unknown. We have established a fluid phase biopsy approach that identifies circulating tumor cells (CTCs) without using surface protein-based enrichment and presents them in sufficiently high definition(More)
Pancreatic cancer is one of the most deadly carcinomas worldwide. Although gemcitabine as the standard chemotherapy agent has been proven to be effective, the response rate remains at 5.4% and the 5-year survival rate is extremely poor. Ursolic acid (UA) is a small molecule compound extracted from Chinese herbs as(More)
This review summarizes some of the recent advances in obesity research and describes how we and others have built upon these findings to better understand the impact of obesity on granulosa cells, cumulus cells and oocytes within the ovaries of obese females. Obesity is associated with lipid accumulation in non-adipose tissue cells and the induction of(More)
BACKGROUND Estimating the number of genes in human genome has been long an important problem in computational biology. With the new conception of considering human as a super-organism, it is also interesting to estimate the number of genes in this human super-organism. PRINCIPAL FINDINGS We presented our estimation of gene numbers in the human gut(More)
Biometrics authenticated schemes using smart cards have attracted much attention in multi-server environments. Several schemes of this type where proposed in the past. However, many of them were found to have some design flaws. This paper concentrates on the security weaknesses of the three-factor authentication scheme by Mishra et al. After careful(More)
