Is glucose uptake in human brown adipose tissue impaired upon fasting-induced insulin resistance?
Cold-stimulated glucose uptake in BAT is strongly reduced upon prolonged fasting. When cold-stimulated glucose uptake in BAT is also reduced under other insulin-resistant states, such as diabetes, cold-induced activation of BAT may not be a valid way to improve glucose clearance by BAT under such conditions.
Eplerenone suppresses inducibility of sustained atrial tachyarrhythmias, selectively prolongs atrial ERPs, and attenuates LV diastolic remodeling in RVP-induced CHF. Aldosterone blockade may be a promising new approach for atrial tachyarrhythmia prevention in CHF.
