background: the selection of blastocyst warmed for transfer is based on pre-freeze morphology in vitrified-warmed single blastocyst transfer cycles. but, it is controversial which parameter of blastocyst morphology most closely related to the clinical outcomes. objective: to estimate the effect of blastocoele expansion, trophectoderm (te) morphology grade, and inner cell mass (icm) morphology g...

the use of ovarian stimulation for infertility treatment is associated with side effects of ovarian hyperstimulation syndrome (ohss) and potential cancer risk. this is also true in high risk women such as those polycystic with ovary (pco) and polycystic ovarian syndrome (pcos). in vitro maturation (ivm) of oocytes was primarily developed to make ivf safe for women with pco and at high risk of o...

background: axotomy causes sensory neuronal loss. reconnection of proximal and distal nerve ends by surgical repair improves neuronal survival. it is important to know the morphology of primary sensory neurons after the surgical repair of their peripheral processes. methods: animals (male wistar rats) were exposed to models of sciatic nerve transection, direct epineurial suture repair of sciati...

background: in this study, we evaluated the protective effects of water hyacinth root powder (hrp) on arsenic-mediated toxic effects in mice. methods: swiss albino mice, used in this study, were divided into four different groups (for each group n=5). the control group was supplied with normal feed and water, arsenic group (as-group) was supplied with normal feed plus arsenic (sodium arsenite)-...

this experiment was conducted to investigate the effect of different levels of saccharomyces cerevisiae cell wall on performance, carcass traits and intestinal morphology in broilers. in this experiment 240 ross- 308 broilers were used in 4 treatments, 5 replicates and 12 bird in each replicate in a completely randomized design for 42 days. the treatments included: 1) control group (without sac...

background: multiple factors have been suggested for prediction of pregnancy in intracytoplasmic sperm injection (icsi) cycles such as the number of injected oocytes, fertilization rate, embryo morphology and quality of transferred embryos. predictive value of these factors is important in icsi outcome. objectives: to evaluate the role of embryo morphology for prediction of pregnancy in icsi cy...

background and aim:  several reports have been published on the successful application of various bone substitute materials (bsm). appropriate physiologic and histologic characteristics and reactions of these materials against host cells are critically important. in this study, the biocompatibility of a new bone substitute material has been evaluated. materials and methods: in this experimental...

In this study, silver nanoparticles were synthesized  using the fungus, Aspergillus fumigatus. The effects of three independent variables including glucose content of culture media, initial pH and initial spore concentration on biosynthesis of silver nanoparticles were investigated. These variables affect cell morphology, cell mass, size and morphology of silver nanoparticles and degree of silv...
