The aim of this study was to apply a recently developed cell culture system to the problem of identifying possible etiologies of altered retinal maturation. Using techniques of electrophysiology and neuropharmacology, it was possible to monitor the release of acetylcholine at synapses formed by cultured retinal neurons derived from the fetal rat. The major finding of this study was that the fun...

Campylobacter fetus is a gram-negative bacterial pathogen of both humans and animals. Two subspecies have been identified, Campylobacter fetus subsp. fetus and Campylobacter fetus subsp. venerealis, and there are two serotypes, A and B. To further investigate the genetic diversity among C. fetus strains of different origins, subspecies, and serotypes, we performed multiple genetic analyses by u...

Glucosamine 6-phosphate synthase (EC 5.3.1.19) purified from various rat tissues by a procedure involving chromatography on diethylaminoethyl Sephadex and hydroxylapatite were characterized by means of isoelectric focusing. The non-hepatic isozyme, previously reported to be present in Yoshida sarcoma, has a pI of 4.1 and is distinguished from the hepatic isozyme, with a pI of 5.0. The pI 4.1 fo...

A cell culture platform for neuron aggregates has been designed and fabricated as an in vitro model for studying CNS myelination. The device is composed of nine culture chambers each of which has 55 cell trapping sites for culturing neuron aggregates in a spatially controlled environments in parallel. Neuron aggregates prepared from embryonic day 16 rat fetus were cultured with oligodendrocyte ...

objective: to determine the effectiveness of counseling in reducing anxiety of nulliparous pregnant women. materials and methods: in this quasi-experimental study, 110 nulliparous pregnant women were selected out of all pregnant women referring to fatemieh hospital in hamadan, iran. then, the subjects were divided into two groups in experimental and control (55 women in each). the data were col...

introduction: neonatal period damages occur due to mechanical forces (compression, stretching) during the birth process are classified as birth trauma. various maternofetal factors, such as maternal diabetes, breech or other noncephalic presentations and birth weight might have been effective in developing prenatal trauma. shoulder dystocia, which is common in neonates` of diabetic mothers, usu...

The placenta is critical for nourishing the fetus throughout pregnancy, and also produces hormones that alter the metabolic functions of the mother. While the effects of nutrition on fetal development and long-term outcome have been very well documented, there are only a few reports based on studies in rat, sheep, and guinea pigs on how specific nutrients or general nutritional status affect th...
