Background: Setting up an in vitro follicle culture system that resembles in vivo ovary condition has high value in research. Additionally, expression evaluation of folliculogenesis involved genes could lead us to the designing of better culture system. Materials and Methods: ovaries of 12-day-old female NMRI mice were removed, 100-130 μm pre-antral follicles were mechanically isolated from fre...
low seed germination and seedling emergence is one of the main problems in saline areas. seed priming technique has been known as a challenge to improve germination and seedling emergence under different environmental stress. the objective of this research was to evaluate the effect of seed priming with gibberellin, nacl and water on seed germination and seed reserve utilization and germination...
A method for concurrent clearing of energy and reserve market is presented in this paper. The proposed method considers two important objectives in an optimization problem; the first one is including the stochastic nature of power generation variations by applying a probabilistic clearing model and Monte-Carlo simulation; the second one is assignment of energy and reserve capacities to generati...
The present study aims to investigate the effects of monetary and financial shocks on macroeconomic variables in fractional and full reserve banking conditions. To this end, two stochastic dynamic general equilibrium models have been designed in terms of the realities of Iran's economy and then the effects of shocks have been studied. After determining the input values of the model and estima...
It had been known for decades that primordial follicles in mammalian ovaries are assembled with definite numbers and represent the ovarian reserve throughout the reproductive life. Intra-oocyte PI3K/mTOR pathways have been indicated to play a central role on the activation of primordial follicles. Genetic modified mouse models with chronic activation of PI3K/mTOR signals in primordial oocytes s...
OBJECTIVE To assess gonadotrophin secretion, ovarian steroid production and ovarian reserve in PCOS women during the onset of reproductive decline, in order to characterize their ovarian function at this age. STUDY DESIGN Forty PCOS patients and 35 healthy women (35-40 years of age) were included. Clinical history, anthropometry, transvaginal ultrasound and a leuprolide acetate test (10 μg/kg...
BACKGROUND The possibility that a specific cytokine profile could be detected in the ovaries of patients with polycystic ovarian syndrome (PCOS) was investigated. METHOD Enzyme-linked immunosorbent assay (ELISA) or bioassays were used to assess the concentrations of leukaemia inhibitory factor (LIF), tumour necrosis factor, interleukin 11, gamma interferon, progesterone and oestradiol in foll...
the present study reports the changes in the phytoplankton community structure in taklong island national marine reserve (tinmar), guimaras island, philippines. quantification of pah yielded undetectable results, whereas, primary productivity, phytoplankton density, and diversity values were higher as compared to samples before the oil spill and samples from the reference site. sixty-nine gener...
