Photolyses of the thiohydroximate ester derivatives 13 and 21 of the 4- (benzyl-seleno)-2-azetidinoines 7 and 20, afford the 1-aza-7-oxo-4-selenabicyclo- [3.2.0]heptane ring systems 14 and 21 in good to moderate yield in processes that presumably involve intramolecular homolytic substitution at selenium with expulsion of benzyl radical. Extension of this methodology to the preparation of deriva...

Genetic modification of whole-cell cancer vaccines to augment their efficacies has a history of over two and a half decades. Various genes and gene combinations, targeting different aspects of immune responses have been tested in pursuit of potent adjuvant effects. Here we show that co-expression of two cytokine members of the common cytokine receptor γ-chain family, IL-21 and IL-7, in whole-ce...

AIMS To investigate separately for men and women whether moderate or high leisure time physical activity, occupational physical activity, and commuting activity are associated with a reduced cardiovascular disease (CVD) and all-cause mortality, independent of CVD risk factors and other forms of physical activity. METHODS AND RESULTS Prospective follow-up of 15,853 men and 16,824 women aged 30...

The Cobb × Cobb 500 slow-feathering male is a fast early-growth broiler grown under variable feeding programs and amino acid (AA) densities. An experiment was conducted using diets with increased ideal protein densities in a feeding program of 1 to 7 d, 8 to 21 d, 22 to 35d, and 36 to 42 d. Diets had ratios between essential digestible (D) AA and DLys (DAA:DLys) as follows: TSAA, 75%; DThr, 65%...

BACKGROUND Recreational physical activity has been consistently associated with lower breast cancer risk, but there is a need to study the intensity and duration of activity that are critical to reduce the risk. The aim of this study was to examine the influence of moderate and vigorous intensity of recreational physical activity performed at different age periods on breast cancer risk. MATER...

objective(s) during recent years, there has been an increasing interest in contribution of environmental pollutants as heavy metals to human male infertility. present study was aimed to investigate the effects of maternal lead acetate exposure during lactation on postnatal development of testis in offspring rats. materials and methods a total of 60 female rats randomly divided into four equal g...
