Hydrolase in Cardiac Subcellular Fractions of Hyperthyroid Rabbits
Activities of phosphatidate phosphohydrolase and palmitoyl-CoA hydrolase were determined in cardiac subcellular fractions prepared from rabbits which had received tri-iodothyronine and from hamsters with hereditary cardiomyopathy (strain BIO 14.6). 1. Both mitochondrial and microsomal fractions of hyperthyroid rabbit hearts produced 4-5 times as much diacylglycerol 3-phosphate from glycerol 3-p...
متن کاملImmunologic reactions involving sperm cells and preimplantation embryos.
Evidence that sperm cells share or impart antigenic specificities to fertilized ova and cleaving embryos in animals was first demonstrated indirectly in female animals isoimmunized against sperm or testis cells. While early studies often gave conflicting results, postfertilization infertility effects were occasionally reported. The systematic analysis in animals of anti~ertility e~ects after im...
متن کاملACUPUNCTURE AND FEMALE INFERTILITY About infertility
About infertility Infertility is the inability of a couple to get pregnant despite having regular unprotected sex. A couple is regarded as infertile if, after regular sexual intercourse, they have not conceived in two years. It is estimated that one in seven UK couples has difficulty conceiving (HFEA, 2006). Identifiable causes of infertility include: ovulatory disorders in 27% of couples; tuba...
متن کاملSperm counts and sperm sex ratio in male infertility patients.
In recent years, investigators have noted a trend toward a declining proportion of male births in many industrialized nations. While men bear the sex-determining chromosome, the role of the female partner as it pertains to fertilization or miscarriage may also alter the gender ratio. We attempted to determine a man's secondary sex ratio (F1 generation) by directly examining the sex chromosomes ...
متن کاملImpaired hyperactivation of human sperm in patients with infertility.
Hyperactivation and acrosome reaction are prerequisite steps for sperm to be able to fertilize an oocyte. In mammals, hyperactivation is defined as a movement pattern seen in spermatozoa at the site and time of fertilization. The objectives of the present experiments were to analyze the process of hyperactivation and to investigate its relationship with progesterone evoked intracellular calcium...
