The effect of seminal plasma, as well as some seminal plasma fractions, on the heterogeneity and viability of frozen-thawed ram spermatozoa was studied. Fresh and frozen sperm samples were simultaneously assessed by a routine semen-quality assay and centrifugal countercurrent distribution (CCCD) in an aqueous two-phase system analysis. All samples used for this study were obtained from Salz ram...

This study determines the effect of different commercial diluents on quality frozen Simmental semen. The extraction fresh semen from 3 bulls using an artificial vaginal method was performed twice a week. Fresh with motility >70% further processed to one-step dilution method, and used were Andromed®, Optixcell®, Steridyl®. diluted packed into mini-straws, equilibrated, frozen, stored for test...

BACKGROUND AND PURPOSE Dabigatran-etexilate (DE) recently has been approved for stroke prevention in atrial fibrillation. However, lack of effective antagonists represents a major concern in the event of intracerebral hemorrhage (ICH). The aims of the present study were to establish a murine model of ICH associated with dabigatran, and to test the efficacy of different hemostatic factors in pre...

The integrity of sperm progesterone (P4) receptor(s) and its response to steroid stimulation might be crucial for the maintenance of sperm fertilizing ability after cryopreservation. The aim of the current investigation was to study the effect of cryo-procedures on canine sperm P4 receptor(s). In addition, alteration of P4 receptor(s) at the molecular level and their functional integrity follow...

during spring, summer and winter seasons, sistani donor cows, with normal reproductive status, were superovulated and embryos were recovered non-surgically on day 7. grade a blastocyst embryos were either transferred fresh (spring) or frozen (summer and winter). recovered embryos during summer and winter were exposed to glycerol and frozen using conventional method. during spring season, recipi...

Sulphate size distributions were measured at the coastal station of Mumbai (formerly Bombay) through 1998, during the Indian ocean experiment (INDOEX) "rst "eld phase (FFP), to "ll current gaps in size-resolved aerosol chemical composition data. The paper examines meteorological, seasonal and source-contribution e!ects on sulphate aerosol and discusses potential e!ects of sulphate on regional c...

Specimens of plasma from 51 agricultural workers were divided into several portions for freezing and storage. Periodic assays (in duplicate) for cholinesterase activity in each specimen were compared with the initial values obtained on each fresh, unfrozen specimen. Freezing and/or thawing results in loss of approximately 30% of the plasma cholinesterase activity. It is not possible to use divi...
