The prevalence of HIV has been continually increasing both in urban and rural Ethiopia. As yet, there has been no report on the magnitude of the problem in the elderly and rural population. This study assessed the seroprevalence of HIV and syphilis infection among 706 elderly and predominantly rural subjects in Northwest Ethiopia. Socio-demographic information was collected using a structured q...

The molecular structures of vanillin (4-hydroxy-3-methoxybenzaldehyde), isovanillin (3-hydroxy-4-methoxybenzaldehyde) and ethylvanillin (3-ethoxy-4-hydroxybenzaldehyde) were determined by means of gas electron diffraction. Among them, vanillin and ethylvanillin have a vanilla odor but isovanillin smells differently. The nozzle temperatures were 125 °C, 173 °C and 146 °C, for vanillin, isovanill...

This study was conducted to describe the minimum detection limit, reproducibility, accuracy, specificity and parallelism of different pregnancy-associated glycoprotein radioimmunoassay (PAG-RIA) systems: RIA-497, RIA-706, RIA-780, RIA-809 and RIA-Pool. Their ability to distinguish between non-pregnant and pregnant females at day 30 after artificial insemination (AI) was investigated. The antise...

BACKGROUND Evidence from experimental and epidemiologic studies suggests that vitamin B6 may reduce the risk of breast cancer. METHODS We examined the association of prediagnostic plasma concentrations of pyridoxal-5'-phosphate (PLP), an active form of vitamin B6, with postmenopausal breast cancer risk in a case-control study nested in the multiethnic cohort in Hawaii and Southern California,...

Poultry meat is considered to be a major vector of transmission of Campylobacter, either directly, through consumption of poorly prepared product or cross-contamination, or indirectly, through introduction of the bacterium into the food production environment. Efficient detection of Campylobacter is intrinsic to the management of the pathogen during poultry production. The TECRA Campylobacter V...

We have obtained new optical and extreme ultraviolet (EUV) spectroscopy of the ultramassive white dwarf EUVE J1746–706. We revise Vennes et al.’s (1996a, ApJ, 467, 784) original estimates of the atmospheric parameters and we measure an effective temperature of 46, 500± 700 K and a surface gravity log g = 9.05± 0.15 (∼ 1.2M⊙), in agreement with Balmer line profiles and the EUV continuum. We deri...

The High chlorophyll fluorescencel06 (HcflO6) gene in maize is required for chloroplast membrane biogenesis, and the hcf706muml allele is caused by the insertion of a Robertson‘s Mutator Mul element into the promoter of the gene. Seedlings homozygous for hcfl06-muml are pale green and die 3 weeks after germination, but only in the presence of Mutator activity conferred by active, autonomous Mu ...
