05), and IL-1RA treatment initiated at 24 hr postinjury resulted in weaker but still significant neuroprotection. IL-1RA treatment also reduced the number of microglial cells significantly when initiated within 36 hr postinjury (P < 0.05). In conclusion, IL-1RA exhibits significant neuroprotective effects in this in vitro model of excitotoxic injury even after delayed application. (C) 2008 Wiley-Liss, Inc.”
“It has been previously reported that overweight and obese individuals perceive exercise as more difficult than their lean counterparts, and this difference may not be solely attributed
to physiological differences. Therefore, we tested the hypothesis that individual differences in the perception of exercise difficulty during exercise, independent of concurrently measured physiological markers of exertion, are predictive of weight regain, after completion of a weight loss program. A total of 113 formerly overweight women who had learn more previously completed a weight-loss program to achieve a normal body weight (BMI <25 kg/m(2)) underwent a submaximal aerobic exercise task while Silmitasertib measures of physiological and perceived exertion (rating of perceived exertion (RPE)) were recorded. Weight gain was assessed following a subsequent 1-year free-living
period. Average weight regain 1 year following the intervention was 5.46 +/- 3.95 kg. In regression modeling, RPE (beta = 0.21, P = 0.01), but not physiological exertion (beta = 0.02, P = 0.81), during the submaximal exercise task was positively associated with 1-year weight regain following weight loss in premenopausal women, independent of measured confounding variables. The association between RPE and weight regain suggests that perception of exercise difficulty is an important predictor of weight

“There is growing interest regarding the role of the right inferior frontal gyrus (RIFG) during a particular form of executive control referred to as response inhibition. However, tasks used to examine neural activity at the point of response inhibition have rarely controlled for the potentially confounding effects of attentional demand. In particular, it is unclear whether the RIFG is specifically involved in inhibitory control, or is involved more generally in the detection of salient or task relevant cues. The current fMRI study sought to clarify the role of the RIFG in executive control by holding the stimulus conditions of one of the most popular response inhibition tasks-the Stop Signal Task-constant, whilst varying the response that was required on reception of the stop signal cue. Our results reveal that the RIFG is recruited when important cues are detected, regardless of whether that detection is followed by the inhibition of a motor response, the generation of a motor response, or no external response at all.
