Cardiac stent patients with diabetes may benefit from drug that counteracts the effects of leptin

The naturally high levels of leptin in diabetic patients may reduce the effectiveness of drug-eluting stents used to treat heart blockages, but using a chemical that differs from the one commonly used to coat stents could counteract this effect.

Attitudes towards assisted reproduction and preimplantation genetic diagnosis

According to an international survey by the BBVA Foundation conducted this year, citizens in advanced societies view assisted reproduction techniques in general and in vitro fertilization in particular as firmly acceptable alternatives for people with fertility problems (over 7 points on an acceptance scale from 0 to 10 in twelve of the fifteen survey countries).

Researchers find brain's reward and stress signaling circuits are intertwined in complex ways

Vanderbilt University Medical Center investigators have now discovered a functional link between reward and stress. They found that dopamine - the brain's chief reward signal - works through corticotrophin-releasing factor (CRF) - the brain's main stress signal - to increase the activity of a brain region involved in addiction relapse.
