We present the outcomes of a Chandra X-ray Observatory snapshot study of five nearby Herbig Ae/Be (HAeBe) stars which are kinematically linked with the Oph-Sco-Cen Association (OSCA). Optical photometric and spectroscopic followup was conducted for the HD 104237 field. The principal result is the discovery of a compact group of pre-main sequence (PMS) stars associated with HD 104237 and its cod...
The interaction between egg and sperm is the first necessary step of fertilization in all sexually reproducing organisms. A decade-long search for a protein pair mediating this event in mammals culminated in the identification of the glycosylphosphatidylinositol (GPI)-anchored glycoprotein Juno as the egg plasma membrane receptor of sperm Izumo1 [1,2]. The Juno-Izumo1 interaction was shown to b...
Recent evidence suggests that dietary intake of vitamins, in particular the B-vitamins including B6, B9 and B12 may have a number of positive effects on mood and stress. Given the effects of stress on a range of biological mechanisms including the endocrine system, it could be reasonably expected that multivitamin supplementation may also affect markers of these mechanisms such as diurnal corti...
Generally a biological system is said to be permanent if under small perturbations none of the species goes extinction. In 1979 P. Schuster, K. Sigmund, and R. Wolff [15] introduced concept permanence as stability notion for systems that models self-organization macromolecules. After, in 1987 W. Jansen rid="b9">9], J. Ho...
Background and aims The dietary pattern followed during pregnancy, specifically healthy patterns such as the Mediterranean diet, is a key factor in mother’s offspring’s health. Pregnant women intake not enough to cover micronutrient requirements of higher adherence diet may improve quality nutritional density. aim present study was describe nutrient pregnancy evaluate whether high associated wi...
Breast cancer is a genetic disease caused by the accumulation of mutations in neoplastic cells and responsible for highest morbidity mortality. In this study, blood serum samples from 45 breast patients 32 healthy individuals (control group) were used. The amounts vitamins (A, E, β-carotene, C, B1, B2, B3, B5, B6, B9 B12), glutathione (GSH, GSSG) stress biomarkers (4-HNE, MDA) determined HPLC. ...
