A sound wave traveling in air causes oscillations in pressure above or below the ambient atmospheric pressure. In acoustic theory, a sound source is mainly characterized by its amplitude and frequency (f). The acoustic incident pressure field (p̃) at an observation point, x, due to a point source located at xs is given by Equation 1 where, ω = 2πf , c0 is(More)
Testicular testosterone synthesis begins with cholesterol transport into mitochondria via steroidogenic acute regulatory (StAR) protein in Leydig cells. Acute heat stress is known to obstruct testicular steroidogenesis by transcriptional repression of StAR. In contrast, chronic heat stress such as cryptorchidism or varicocele generally does not affect(More)
Cells cope with temperature elevations, which cause protein misfolding, by expressing heat shock proteins (HSPs). This adaptive response is called the heat shock response (HSR), and it is regulated mainly by heat shock transcription factor (HSF). Among the four HSF family members in vertebrates, HSF1 is a master regulator of HSP expression during(More)
