Macromolecular Synthesis in the Urinary and Reproductive Systems
نویسنده
چکیده
The kidneys of mammals microscopically consist of the nephrons, which can be divided into two portions, the renal corpuscles and the uriniferous tubules. The renal corpuscles are composed of the glomeruli which are covered with the Bowman’s capsules. They are localized in the outer zone of the kidney, the renal cortex, while the uriniferous tubules are composed of two portions, the proximal portions and the distal portions which can further be divided into several portions which run from the outer zone of the kidney, the renal cortex, to the inner zone, the medulla. We studied the DNA synthesis by 3H-thymidine radioautography in 3 groups of ddY mouse embryos from prenatal day 13 (Fig. 16A), day 15 (Fig. 16B) to day 19 in vitro, as well as perinatal mice from embryonic day 19 to postnatal day 1, 8, 30, 60 and 365 (1 year) in vivo (Hanai 1993, Hani et al. 1993, Hanai and Nagata 1994a,b).

In this paper, a series of well-defined polyethylene-b-polytetrafluoroethylene diblock copolymers (PE–b– PTFEs) were prepared by a coupling reaction of hydroxyl-terminated polyethylene (PE–OH) and isocyanateterminated 1H,1H-perfluoro-1-tetradecanol (PFDO–NCO). PE–OH was prepared by the coordination chain transfer polymerization using 2,6-bis[1-(2,6-diisopropylphenyl)imino ethyl] pyridine iron (...

متن کاملThe effect of sugar cane molasses on the immune and male reproductive systems using in vitro and in vivo methods
Objective(s): Sugar cane molasses is a commonly used ingredient in several food products. Contrasting reports suggest that molasses may have potential adverse or beneficial effects on human health. However, little evidence exists that examines the effects of molasses on the different physiological systems. This study investigated the effects of sugar cane molasses on various physiological syste...
متن کاملReproductive enhancement in buffalo: looking at urinary pheromones and hormones
The success of conception in buffalo is greatly dependent on precise estrus detection and time of artificial insemination (AI). Various visual, behavioral, biochemical and gyneco-clinical parameters have been tracked closely and a cost-effective combinatorial model has been developed to detect estrus in buffaloes. Pheromones play pivotal roles in reproduction and behavior of mammals. Urine, an ...
متن کاملRate of urinary tract infection after urodynamic study in pelvic floor clinic
Background: One of the complications of urodynamic study is urinary tract infection. The aim of this study was to determine the rate of urinary tract infection (UTI) after UDS in patients referred to the pelvic floor clinic with regard to the specific conditions of these patients, such as presence of pelvic organ prolapse and high post voiding residual volume (PVR). Methods: In a prospective d...
