Age-related changes in microvillar cells of rat olfactory epithelium.
The nature and function of microvillar cells (MVCs) of the mammalian olfactory epithelium (OE) are little understood. Previous studies have examined MVC morphology in the developing and mature OE, but not in the aged OE. The present study investigated the effect of aging on MVCs of the OE in male Sprague-Dawley rats using histological and immunohistochemical methods. OE of aged rats contained M...
متن کاملHormonal Regulation of MicroRNA Expression in Steroid Producing Cells of the Ovary, Testis and Adrenal Gland
BACKGROUND Given the emerging roles of miRNAs as potential posttranscriptional/posttranslational regulators of the steroidogenic process in adrenocortical and gonadal cells, we sought to determine miRNA profiles in rat adrenals from animals treated with vehicle, ACTH, 17α-E2 or dexamethasone. Key observations were also confirmed using hormone (Bt2cAMP)-treated mouse Leydig tumor cells, MLTC-1, ...
متن کاملAge-related changes in rat retina.
PURPOSE To describe the changes in rat retina occurring with ageing by means of histological methods, scanning electron microscopic observations and morphometrical data; and to study by means of biochemical methods the amount of protein content in retinal tissues. METHODS Samples of fresh retinal tissue obtained from young, adult, and aged rats were studied by means of traditional histologica...
متن کاملAge-related changes in sleep in the rat.
Human sleep in old age is characterized by a number of changes, including reductions in sleep efficiency, amounts of visually scored slow-wave and REM sleep, and amplitude of the diurnal sleep/wake rhythm. In older rats, some, but not all, of these traits have been reported, including a decrease in the mean duration of sleep bouts, an increase in the number of sleep bouts, and a modest reductio...
متن کاملAge-related changes in auditory temporal processing in the rat.
Presbycusis, as the deterioration of hearing ability occurring with aging, can be manifested not only in a shift of hearing thresholds, but also in a deterioration of the temporal processing of acoustical signals, which may in elderly people result in degraded speech comprehension. In this study we assessed the age-related changes in the temporal processing of acoustical signals in the auditory...
