Salmonella typhi was isolated from 369 and Salmonella paratyphi A was isolated from 6 of 515 Vietnamese patients with suspected enteric fever. Compared with conventional broth culture of blood, direct plating of the buffy coat had a diagnostic sensitivity of 99.5% (95% confidence interval [CI], 97.1 to 100%). Blood bacterial counts were estimated by the(More)
Previous morphological and molecular analyses failed to resolve the phylogenetic position of the critically endangered saola (Pseudoryx nghetinhensis) with respect to its placement in Bovina (cattle, bison, and yak) or Bubalina (Asian and African buffaloes). In the present study, G- and C-banding, Ag-staining and FISH with 28S and telomeric probes was(More)
OBJECTIVE Asian Americans have low prevalence of overweight/obesity based on standard BMI cut points yet have higher rates of diabetes. We examined the prevalence of overweight/obesity, using lower BMI cut points recommended by the World Health Organization (WHO) for Asians, and diabetes in Asian American subgroups in California. METHOD Secondary analysis(More)
BACKGROUND Sepsis remains a major clinical challenge in intensive care units. The difficulty in developing new and more effective treatments for sepsis exemplifies our incomplete understanding of the underlying pathophysiology of it. One of the more widely used rodent models for studying polymicrobial sepsis is cecal ligation and puncture (CLP). While a(More)
Dietary phytochemicals have been shown to be protective against various types of cancers. However, the precise underlying protective mechanisms are poorly understood. In the present study, we report that treatment of A549 cells with quercetin resulted in a dose-dependent reduction in cell viability and DNA synthesis with the rate of apoptosis equivalent to(More)
BACKGROUND Chronic hepatitis B infection rates among Vietnamese-American adults range from 7 to 14%. Carriers of HBV are over 200 times more likely to develop liver cancer than non-carriers, and Vietnamese males have the highest liver cancer incidence rate of any ethnic group in the USA (41.8 per 100,000). Culturally and linguistically appropriate(More)
BACKGROUND Colorectal cancer (CRC) screening rates are increasing, but they are still low, particularly in ethnic minority groups. In many resource-poor settings, fecal occult blood test (FOBT) is the main screening option. INTERVENTION Culturally tailored telephone counseling by community health advisors employed by a community-based organization,(More)
Mitigating the unequal burden of cancer often involves conducting community-based trials to develop effective intervention strategies to promote cancer-related health behaviors. However, this is challenging due to the simultaneous influence of numerous factors, at multiple levels in the socio-ecological context, on health behavior. A sound conceptual(More)
This study examines the relationship of burn injury and plasma levels of conjugated dienes, total sulfhydryl groups, and vitamin E in patients with thermal injuries. Plasma neopterin levels were determined as an index of macrophage activity and serine elastase as an index of polymorphonuclear cell activation. Thirteen patients with burns, six survivors and(More)
Differentiation of oligodendrocyte progenitor cells (OPCs) into mature oligodendrocytes requires extensive changes in gene expression, which are partly mediated by post-translational modifications of nucleosomal histones. An essential modification for oligodendrocyte differentiation is the removal of acetyl groups from lysine residues which is catalyzed by(More)
