Oscillations of the period (per) and timeless (tim) gene products are an integral part of the feedback loop that underlies circadian behavioral rhythms in Drosophila melanogaster. Resetting this loop in response to light requires the putative circadian photoreceptor cryptochrome (CRY). We dissected the early events in photic resetting by determining the mechanisms underlying the CRY response to...
BACKGROUND The biological clock synchronizes the organism with the environment, responding to changes in light and temperature. Drosophila CRYPTOCHROME (CRY), a putative circadian photoreceptor, has previously been reported to interact with the clock protein TIMELESS (TIM) in a light-dependent manner. Although TIM dimerizes with PERIOD (PER), no association between CRY and PER has previously be...
Period determination in the mammalian circadian clock involves the turnover rate of the repressors CRY and PER. We show that CRY ubiquitination engages two competing E3 ligase complexes that either lengthen or shorten circadian period in mice. Cloning of a short-period circadian mutant, Past-time, revealed a glycine to glutamate missense mutation in Fbxl21, an F-box protein gene that is a paral...
Traditional studies of infant cry signals focus more on non-pathology-based classification of infants. In this paper, we introduce a noninvasive health care system that performs acoustic analysis of unclean noisy infant cry signals to extract and measure certain cry characteristics quantitatively and classify healthy and sick newborn infants according to only their cries. In the conduct of this...
Spores from Cry(sup+) strains of Bacillus thuringiensis bound fluorescein isothiocyanate-labeled antibodies specific for the 65-kDa activated Cry 1Ac toxin, whereas spores from Bacillus cereus and Cry(sup-) strains of B. thuringiensis did not. The Cry(sup+) spores could be activated for germination by alkaline conditions (pH 10.3), whereas Cry(sup-) spores could not. Once the surrounding exospo...
background: the mammalian ovary is controlled by a number of biological rhythms, which regulate the recruitment and release of mature oocytes. the main objective of this study was to investigate the role of cellular clock proteins during follicle maturation in the mouse estrous ovary. methods: immunohistochemical (ihc) studies were performed on ovaries from 50 estrous staged mice culled at two ...
ABSTRACT This study aimed to evaluate different periods of chromium yeast (CrY) supplementation on growth performance and quantitative carcass characteristics growing-finishing pigs. We used eighty barrows (Duroc/Pietran × Large White/Landrace) with an initial body weight 24.5±2.4 kg. A completely randomized block design was within four dietary CrY (control diet: CrY-free, from 25 110 kg; Cr25-...
