Cocaine use can make otherwise resistant immune cells susceptible to HIV

In many ways, the spread of HIV has been fueled by substance abuse. Shared needles and drug users’ high-risk sexual behaviors are just some of the ways that narcotics such as cocaine have played a key role in the AIDS epidemic in much of the world.

There is, however, relatively little research into how drugs can impact the body’s defenses against the virus. But a new UCLA study published in the October issue of the Journal of Leukocyte Biology examines how cocaine affects a unique population of immune cells called quiescent CD4 T cells, which are resistant to the virus that causes AIDS.

A large, newly published study that includes more than 13,500 postmenopausal women has yielded the most definitive associations yet between certain lifestyle and demographic factors and levels of a promising early biomarker of type 2 diabetes risk.

PROVIDENCE, R.I. [Brown University] — Over the last decade researchers have amassed increasing evidence that relatively low levels of a protein called sex hormone binding globulin (SHBG) can indicate an elevated risk of type 2 diabetes and metabolic syndrome years in advance. (more…)

Welches Fleisch soll es sein? Warum Bio besser ist

Wir Deutsche essen sehr viel Fleisch. Das hat Folgen. Intensivtierhaltung ist bei uns längst die Regel. Dabei werden die Tiere den Bedingungen angepasst und nicht umgekehrt. Auf einem Biohof dagegen zählen die Bedürfnisse der Tiere. Bio-Fleisch ist auch besser für das Klima – und für unser Trinkwasser.

Hausschweine haben einen großen Bewegungsdrang und sind sehr reinlich und neugierig. Bio-Bauern berücksichtigen das und bemühen sich um eine tiergemäße Haltung. Ihre Schweine bekommen Stroh als Spielzeug, zum Nestbau und zum Wühlen. Liege- und Kotplätze sind voneinander getrennt. Bioschweinen steht ein Auslauf im Freien zur Verfügung, wo sie Regen, Sonne, Wind und Gerüche erleben können – im Gegensatz zur reizarmen Umgebung eines konventionellen Stalls. Außerdem stärkt das ihr Immunsystem und sie brauchen weniger oder keine Antibiotika. (more…)

When a CT scan revealed a 24-inch clot stretching from his legs into his heart, doctors feared the mass could break loose and lodge in his lungs, blocking oxygen and killing him instantly.
