The in vitro accelerated aging of conventional and microfilled composite restorative materials and a sealant was studied. Volume loss/surface area ranged from 2.0 x 10(-3) mm3/mm2 for I to 7.3 x 10(-3) mm3/mm2 for SF after 900 h of aging. Surface morphology of the conventional composites was characterized by crazing and exposure of filler particles. The surfaces of the microfilled composites al...

This paper proposes a suitable method for increasing effective surface area of electrodeposited WO3 thin films. This is done because effective surface area improves optical and electrochromic properties in smart windows. Therefore, we investigated precursor aging atperoxytungstate precursor (0, 24, 48 and 72 h). Experiments showed by increasing aging time of the precursor solution, larger aggre...

The incidence of type 2 diabetes significantly increases with age. The relevance of this association is dramatically magnified by the concomitant global aging of the population, but the underlying mechanisms remain to be fully elucidated. Here, some recent advances in this field are reviewed at the level of both the pathophysiology of glucose homeostasis and the cellular senescence of pancreati...

introduction: d-galactose (d-gal) is well known as an appropriate agent to induced aging effects in the in vivo and in vitro models. in the present study, we selected crocin, the main constituent of crocus sativus l. (saffron), against d-gal cytotoxicity in human neuroblastoma sh-sy5y cells. materials and methods:  cells were pretreated with crocin (25-500 µm) for 24 h and then exposed to d-gal...

BACKGROUND Aging contains morphological and functional deterioration in biological systems. D-galactose (D-gal) generates free radicals and accelerates aging. Portulaca oleracea (Purslane) may have protective effect against oxidative stress. OBJECTIVE Purslane ethanolic extract effects were evaluated on antioxidant indices and sex hormone in D-gal aging female mice. MATERIALS AND METHODS 48...
