Sperm require high levels of energy to ensure motility and acrosome reaction (AR) accomplishment. The AMP-activated protein kinase (AMPK) has been demonstrated to be strongly involved in the control of these properties. We address here the question of the potential role of calcium mobilization on AMPK activation and function in chicken sperm through the Ca(2+)/calmodulin-dependent protein kinas...
We have previously shown that lentiviral vectors can be used to generate transgenic chickens efficiently and that expression of introduced transgenes is not silenced on transmission through the germline. Transgene expression can be targeted in the predicted tissue-restricted manner, for example: muscle-specific expression is restricted to skeletal muscle using the rat myosin light chain 3 gene ...

The present study evaluated supplementation of zinc from different sources during chicken semen cryopreservation on post-thaw quality and fertility. Adult White Leghorn was cryopreserved using 4% dimethyl sulfoxide (DMSO) in Sasaki diluent (SD). In the cryomixture oxide (6.25 12.5 µM) sulphate (100 200 added cryopreserved. plastic straws were thawed at 5°C for 100 sec samples sperm motility, li...
Sperm receptors are located in the mammalian egg extracellular coat, or zona pellucida. Mouse and hamster sperm receptor glycoproteins, mZP3 (83 x 10(3) M(r)) and hZP3 (56 x 10(3) M(r)), respectively, have very similar polypeptides (44 x 10(3) M(r); 81% identical) that are glycosylated to different extents. Purified mZP3 and hZP3 can bind to mouse sperm, prevent them from binding to eggs and in...
Collagen associated hydrolysates have desirable characteristics for various industrial applications [1,2]. They have been used as important biomaterial in medical applications because of their biodegradability and weak antigenicity [3]. In addition, intracellular and extra-cellular self-assembly of polypeptide chains and the cross-links between adjacent molecules help collagen fibrils to withst...
Wireless Sensor Network (WSN) technology is the real-time application that growing rapidly as result of smart environments. Battery power one most significant resources in WSN. For enhancing a factor, clustering techniques are used. During forward data WSN, more consumed. In existing system, it works with Load Balanced Clustering Method (LBCM) and provides lifespan network scalability reliabili...
The aim of the study was to standardize the pellet cryopreservation procedure for chicken semen. Mericanel della Brianza male chicken breeders (Italian breed) were used. Pooled semen samples were processed according to the following conditions: (1) dilution in prefreezing extender to 1 versus 1.5 bill cells/mL sperm working concentration (SWC); (2) 6% versus 9% dimethyl acetamide (DMA) concentr...
