Introduction: Hepatitis B virus (HBV) infection disproportionately affects the Hmong ethnic group, with reported US prevalence rates up to 20%, but data for Wisconsin's large Hmong community is lacking. We assessed the prevalence of HBV at Hmong screening events and whether small-group counseling affects HBV knowledge.

Methods: Free HBV screening events were held in Milwaukee, Wisconsin at a Hmong market, a local church, and annual Hmong New Year festival.

Cell and tissue cultures of have been studied extensively as an alternative strategy to improve the production of valuable secondary metabolites. The purpose of this study was to produce callus and suspension cell biomass of good quality and quantity to improve the total alkaloids and bis-indole alkaloids. The young stem derived-callus of variety Quang Ninh (QN) was grown on MS medium supplemented with 1.

Water clarity is the most common indicator of water quality. The purpose of the study was to develop an instrument which can automatically measure water clarity in place of manual measurement by Secchi disk. The instrument is suspended by buoys at the water surface and uses solar energy to measure the light intensity of LED bulbs after passing through a water column; the result is then converted to Secchi depth by using a regression function.

The effects of nicotinamide (NIC) and its natural plant metabolites nicotinic acid (NIA) and trigonelline (TRIG) were studied with respect to defense in plant cell cultures. NIC and NIA could protect against oxidative stress damage caused by 2,2'-azobis(2-amidinopropane) dihydrochloride (AAPH), which generates free radicals. Damage was analyzed as DNA strand breaks in cell cultures of Pisum sativum (garden pea), Daucus carota (carrot), Populus tremula L.

We performed a retrospective case-series study of patients with influenza A (H5N1) admitted to the National Institute of Infectious and Tropical Diseases in Hanoi, Vietnam, from January 2004 through July 2005 with symptoms of acute respiratory tract infection, a history of high-risk exposure or chest radiographic findings such as pneumonia, and positive findings for A/H5 viral RNA by reverse transcription-PCR. We investigated data from 29 patients (mean age 35.1 years) of whom 7 (24.
