Melatonin is an endogenous hormone with neuroprotective effects. Melatonin levels in elderly patients are reduced after surgeries that require anaesthesia. Whether reduced melatonin levels are important for postoperative cognitive dysfunction (POCD) remains unclear. Here, we investigated the effects of melatonin on cognitive dysfunctions induced by isoflurane and mechanisms underlying these eff...

____________________________________________________________________________ Abstract The present ISR describes the encircled energy(EE) analysis of pinhole images made on the M10 WFC3 1R-MUX at the Goddard Space Flight Center (GSFC) Detector Characterization Lab (DCL) on 29 May 2001. Analysis shows that the pinhole image’s centroid is stable within a 1-pixel area and the 80% of the encircled e...

Palm pruning residues are potential pellet raw material, which quite abundant in regions with hot climates. In pelletizing process, material properties and machine features the main factors affecting final quality. this study, 5 mm sieve hole diameter milled palm was pelleted using two different dies moisture. First die (D1) has 25 total length, 17° inlet angle 10 depth. The second (D2) 35 33° ...
