Background Freezing process has destructive effect on different functions of sperm. Therefore, sperm motility was reduced and apoptosis and DNA damage and also levels of reactive oxygen species (ROS) were increased. Insulin-like factor-3 (INSL3) is a member of Relaxin family and directly affects on spermatogenesis and also plays a protective role against apoptosis. Therefore, with due regard to...
feminine voice and narratology in wuthering heights wuthering heights as a general "bronte" work has extraordinary dimensions to it which can make it focal to different ways of interpretation. among other differences the issue of narrative voice is essential in understanding the ultimate purpose of wuthering heights. emily bronte uses different narrators from various focal points speaking of m...
among the low–dimensional allotropes of carbon, nanotubes and graphene have attracted very much attention from nano–science and nanotechnology specialists. they have been proposed as building blocks in nanometer device engineering. however, these structures are not defect–free. in this thesis, we focused on defective carbon nanotubes and graphene, and studied the effect of couple of very common...
Background & Aims: Reactive oxygen species (ROS) generation, induced by the cryopreservation process, can be responsible for mammalian sperm damage. a-tocopherol is known as an effective antioxidant against oxidative stress. The aim of this study was to evaluate the antioxidant effects of a-tocopherol on count, motility, viability, TAC capacity, and DNA integrity rat spermatozoa during semen f...
Background: Freezing and thawing induce a number of insults to the sperm cells, such as low motility and low fertilization capability. For evaluation of hyaluronan (HA) supplementation on sperm characteristics, we investigated the effect of hyaluronan (HA) on mouse sperm before freezing and after thawing. Methods: For this purpose we removed cauda epididimes from 24 male mice with aseptic meth...
Freezing point depression in xylem sap of mangroves was found to range from 0.05 to 0.5 degrees , in desert plants from 0.01 to 0.16 degrees . In crush juices from leaves of Batis and Salicornia, 90% or more of the freezing point depression was made up of sodium and chlorine ions; in mangroves they constituted 50 to 70%, the rest probably being organic solutes. Plants growing in seawater have -...
