Thyroid dysfunctions can produce reproductive problems. Untreated maternal hypothyroidism has serious consequences on development of offspring, resulting in stunted growth and mental retardation. The effects of propylthiouracyl-induced hypothyroidism (0.1 g l(-1) in drinking water starting 8 days before mating, or given to virgin rats for 30 or 50 days) on the serum profiles of hormones related...

Suppressor cell activity for in vitro gamma interferon (IFNgamma) production can be induced in C57BL/6 mice with the T-cell mitogens staphylococcal enterotoxin A and concanavalin A. The suppressor cell lacked mitogen specificity in that injection of mice with either staphylococcal enterotoxin A or concanavalin A induced potent suppressor cell activity that inhibited the in vitro induction of IF...

We propose a model for the dynamics of the immune system by considering the subpopulations of virgin and memory T lymphocytes on a time scale corresponding to the human life span. In the deterministic balance equation we introduce a fluctuating term in order to take into account the chronic antigenic stress. Starting from the hypothesis that the depletion of virgin cells with cytotoxic properti...

1. This response (the “Response”) is made by British Sky Broadcasting Group plc (“Sky”) in response to the complaint made to Ofcom by British Telecommunications plc (“BT”), Setanta Sport Holdings Limited (“Setanta”), Top Up TV Europe Limited (“TUTV”) and Virgin Media Limited (“Virgin Media”), (together the “Complainants”) on the need for a market investigation into the pay TV industry, dated 3 ...

Hypocaloric diet feeding reduced the mitochondrial protein content and whole tissue GDP-binding in interscapular brown adipose tissue from both virgin and lactating rats. A reduction in brown fat lipoprotein lipase activity was also detected in underfed virgin and lactating animals. These results indicate that lactation in the rat, even though it produces a reduction in brown fat activity, does...

For many decades, researchers have investigated the relationships between health status and consumption of extra virgin olive oil. Extra virgin olive oil (and oleic acid) is considered important for the prevention of coronary heart disease. While the biomolecular aspects involving G protein need further research, oleic acid levels in platelets may be a discriminating factor, together with linol...

Numerous medical studies (a study in seven countries, Monika study, Dart studies, etc. ) have shown that olive oil is one of the most important ingredient of "Mediterranean diet" associated with a reduction in cardiovascular disease and certain types of cancerous diseases. Nutritional and health value of virgin olive oil is attributed to the large proportion of monounsaturated fatty acids (main...
