OBJECTIVE The present study aimed to: 1) examine the association of biological maturation effect on children's performance at a motor coordination battery and 2) to assess whether the association between biological maturation and scores obtained in motor coordination tests is mediated by some anthropometric measurement. METHODS The convenience sample consisted of 73 male children aged 8 years...

STATEMENT OF THE PROBLEM The prevalence of overweight and obesity has been increasing markedly in recent years. It may influence growth in pre pubertal children. PURPOSE The purpose of this study was to determine whether increased Body Mass Index (BMI) is associated with accelerated skeletal maturation and dental maturation in six to fifteen years old orthodontic patients in Shiraz, Iran. M...

rate of in vitro maturation of oocytes is one of the challenges of assisted reproductive techniques. in this study we investigated the effects of supplementation of cysteamine on the rate of in vitro maturation of oocytes in two different media. germinal vesicle oocytes were collected from mouse ovary and cultured in two media (tcm199 and meme) with 0, 50, 100, 200, 500 µm/ml cysteamine. number...

Follicle stimulating hormone (FSH) and luteinizing hormone (LH) are commonly added to maturation media to improve cumulus expansion known to be a predictor of oocyte maturation. Therefore, effects of various concentrations of FSH (1000 ng/ml), LH (1000 ng/ml) and FSH + LH (1000 ng/ml each) in comparison with control (without FSH + LH) cultured oocytes were investigated. FSH and LH (1000 ng/ml e...

Speech communication involves integration and coordination of sensory perception and motor production, requiring precise temporal coupling. Beat synchronization, the coordination of movement with a pacing sound, can be used as an index of this sensorimotor timing. We assessed adolescents' synchronization and capacity to correct asynchronies when given online visual feedback. Variability of sync...

background & objectives : different energy substrates and nutrients can greatly influence oocyte nuclear and cytoplasmic maturation. effect of glucose on in-vitro oocyte maturation and subsequent early embryonic development is controversial. the objective of the present study was to verify the effect of various concentrations of glucose on cumulus-oocyte complexes maturation, fertilization and ...

Background: The maturation medium for in-vitro oocyte maturation is usually supplemented with serum. However, supplementation of serum from pregnant women adversely affects the outcome of in-vitro maturation. The purpose of the study was to assess if growth factors or granulosa cell coculture could overcome the adverse effects of pregnant women’s serum. Materials and Methods: The basal maturati...

this study was designed to clarify bilaterally effect of long-time varicocele on left and right testes and to identify the effect of varicocele on maturation divisions during spermatogenesis. moreover, the percentage of seminiferous tubules (sts) with i-viii and ix-xiv stages of spermatogenesis and sperm parameters such as sperm motility and abnormality types were evaluated. the left varicocele...

in vitro maturation (ivm) is a method that immature oocytes in antral follicles are extracted and matured in laboratry conditions. this review has attempted to provide the current knowledge and recent findings in in vitro maturation of oocytes and highlights the most important factors involved in this process. the review is based on literature reports and the author’s experience. in ivm cycles,...

In this study, 3 different spice mixes were added just after blanching to mozzarella cheese produced by high moisture production method. The dough was kneaded and filled into to fibrous cases. After filling process, cheeses were stored for 28 days at 4 °C and 85 % of relative humidity. The following characteristics were measured: color parameters, milk acidity, total dry matter, maturation inde...
