an enzyme-linked immunosorbent assay (elisa) for progesterone measurement in serum or plasma samples using penicillinase as label enzyme is reported. a c3 and c11 derivatives of progesterone were prepared and conjugated to bovin serum albumin (bsa). polyclonal antibody against these two immunogens were prepared in new zealand white rabbits. purified ig fractions of antibodies were immobilized o...
this study investigates the effect of teacher’s repetition as an input enhancement technique in explicit teaching of vocabulary items on efl learners’ later retrieval. to this end, 66 persian speaking english learners, aged 18 - 29, homogenized through a standard proficiency test (opt), were chosen and put into two experimental and control groups, each 33 learners. general service list (gsl), a...
The biological basis for the observed modulation in cytoplasmic progesterone receptors (PgR) of normal mammary gland occurring during mammary development was investigated. Specifically, the relative roles of hormones vs. differentiation on (a) the decrease in PgR concentration during pregnancy and lactation and (b) the loss of mammary responsiveness to estrogen during lactation were examined. P...
Introduction: Ghrelin increases growth hormone secretion and food intake. Growth hormone (GH), steroid hormones and opioids are involved in the regulation of food intake. So, they may have a role in the regulation of ghrelin secretion. We determined the effect of intravenous injections of progesterone, GH and morphine or co-administration of these hormones on ghrelin concentration and body w...
Progesterone and oestrone alone or in combination were administered to sows during early gestation. A dose of 25 mg progesterone and 12-5 mug oestrone injected together for 10,5 or 2 consecutive days during the implantation interval caused increased litter size at term.
Purpose: To evaluate the changes that occur in the motility parameters of progesterone treated sperms during the course of hyperactivation. Materials and Methods: Spermatozoa treated with different doses of progesterone were videotaped after 10 min and 90 min. For each sperm, 1 sec. of movement of the head-midpiece junction was traced from the videotape. For each tracing, seven motility parame...
Objective. To determine if sexual intercourse reduces absorption of vaginal progesterone gel in women and to determine if progesterone is absorbed by the male during intercourse. Study Design. Prospective, randomized, cross over, controlled study of 20 reproductive-aged women and their male sexual partners randomized to receive vaginal progesterone gel (Crinone 8% gel, Actavis Inc., USA) or pla...
background: endometrial development has an important role in blastocyst adhesion and implantation. during ivf cycles, endometrial development is enhanced by progesterone. objective: the aim of this study was to compare ultrastructural and morphometrical characteristics of mice uterine endometrium in natural cycle with those in superovulated cycles received progesterone or sildenafil. materials ...
this research aims at answering the questions about translation problems and strategies applied by translators when translating cultural concepts. in order to address this issue, qualitative and quantitative study were conducted on two groups of subjects at imam reza international university of mashhad. these two groups were assigned as beginner and advanced translation students (10 students). ...
Background: Progesterone is an endogenous immunomodulator that suppresses T cell activation during pregnancy. The stimulation of membrane progesterone receptors (mPRs) would seem to be the cause of rapid non-genomic responses in human peripheral T cells, such as an elevation of intracellular calcium ([Ca2+] i) and decreased intracellular pH (pHi). Mifepristoneimmune cells compared with progeste...
