Mortality Rates and Length of Stay in Patients With Acute Non-ST Segment Elevation Myocardial Infarction Hospitalized for Noncardiac Conditions on Surgical Versus Nonsurgical Services.

Patients hospitalized for noncardiac conditions often experience increased levels of stress and hemodynamic challenges, making them susceptible to acute coronary events. The clinical features, management strategy, and outcomes of inpatient non-ST segment elevation myocardial infarction (NSTEMI) have not been described. This single-center retrospective study identified patients with inpatient NSTEMI from the University of North Carolina Hospitals discharge database in February 2008 to April 2014 using International Classification of Diseases, Ninth Revision (ICD-9) codes.

Deep brain stimulation of the subthalamic nucleus improves reward-based decision-learning in Parkinson's disease.

Recently, the subthalamic nucleus (STN) has been shown to be critically involved in decision-making, action selection, and motor control. Here we investigate the effect of deep brain stimulation (DBS) of the STN on reward-based decision-learning in patients diagnosed with Parkinson's disease (PD). We determined computational measures of outcome evaluation and reward prediction from PD patients who performed a probabilistic reward-based decision-learning task.

Preovulatory changes in the perifollicular capillary network in the rat: role of eicosanoids.

The aim of this study was to evaluate morphometrically the influence of ovulation-inhibiting doses of indomethacin, an inhibitor of the cyclooxygenase pathway, and esculetin and caffeic acid, inhibitors of the lipoxygenase pathway, on the dilatation of the perifollicular capillary network in the theca interna. The development of the perifollicular capillary network as a function of follicular size and the changes in the vascular lumen were examined by light microscopy on a series of semithin cross sections of rat ovaries. The number of capillaries in the theca interna increased linearly with increasing follicle diameter.

The involvement of platelet activating factor in ovulation.

Follicle rupture during ovulation is associated with inflammation-like changes. Because platelet activating factor (PAF) participates in the inflammatory process, the effect of a PAF-specific antagonist, BN52021, on the ovulatory response was tested in rats. BN52021, administered locally, inhibited follicle rupture in rats stimulated to ovulate with human chorionic gonadotropin (hCG).
