We examined muscle burst patterns and burst frequencies for a distinct form of repetitive leg movement recently identified in chick embryos at embryonic day (E)18 that had not been previously studied. The aim was to determine if burst frequencies during repetitive leg movements were indicative of a rhythm burst generator and if maturing muscle afferent mechanisms could modulate the rhythm. Elec...

Milk fat globule-EGF factor (MFG-E8) is a protein that binds to alphavbeta3/5 integrin and phosphatidylserine. It plays a role in apoptotic cell removal, tissue remodeling and intestinal epithelial wound-healing process. In the present study, we examined the expression of MFG-E8 mRNA in the small intestine, liver and lungs during postnatal development. Sprague-Dawley rats were sacrificed at dif...

A global concern that has arisen in the present time due to the constant depletion of the fossil fuels reservoirs and also due to the greenhouse gases emitted by use these fuels has led many researchers to find alternate sources of energy, out of which biodiesels have found a suitable place. Thus, in this effort of finding the compatibility of bio-fuels in present diesel engines, many experimen...

The goal of this study was to determine when fetal breathing movements (FBMs) commence in the rat and to characterize age-dependent changes of FBMs in utero. These data provide a frame of reference for parallel in vitro studies of the cellular, synaptic, and network properties of the perinatal rat respiratory system. Ultrasound recordings were made from unanesthetized Sprague-Dawley rats from e...

Tavuk koryoallantoik membran (CAM) modeli, anjiyogenez çal??malar?nda geli?imsel süreçleri takip etmek için yayg?n olarak kullan?lan bir modeldir. Bu çal??mada, CAM kullan?larak, embriyonik geli?imin 7. ve 20. günleri (E7 E20) aras?nda görülen süreci ???k transmisyon elektron mikroskop analizleri ile edilmi?tir. Ayr?ca, ayn? günlerde al?nan örnekleri meka-nizmalar?nda görevli [Vasküler Endotely...

Studies on cellular interactions in the developing nervous system are greatly facilitated by the availability of tissue culture preparations that contain single or combined populations of neurons and non-neuronal cells (NNCs). Using superior cervical ganglia (SCG) from early E15 rats on air-dried collagen, we were able to prepare cultures containing neurons along with Schwann cells (SCs) as the...

Microcomputerized tomography (micro-CT) allows discriminating very smal lchanges in dental hard tissue volumes. The aim of the present study was to create a new method for obtaining high-resolution, three-dimensional images of dental hard tissue development using micro-CT, and to observe the changes in dental hard tissue development and composition in growing rat pups. Tooth germs from rats at ...

BACKGROUND Cerebral palsy is a nonprogressive motor impairment syndrome that has no effective cure. The etiology of most cases of cerebral palsy remains unknown; however, recent epidemiologic data have demonstrated an association between fetal neurologic injury and infection/inflammation. Maternal infection/inflammation may be associated with the induction of placental cytokines that could resu...

For the first time, genetic variability and differentiation among Ten Synconium white butterfly populations originating from tissue cultured plants maintained in pro-trays under the poly house & green house conditions in Indo American hybrid Seed Company, Bangalore were examined. Random Amplified Polymorphic DNA (RAPD) marker data were obtained and analysed with respect to genetic diversity. Th...
