Background: Infertility problem affects 20-30% of young couples. One of the known causes of spermatogenesis disorder is chemotherapy in patients with cancer which its side effect may last up to the end of the life. The aim of the present study is to investigate the effect of GnRH on viability of ovarian follicles defect produced by anticancer drug. Materials and Methods: In the present study ad...
To check the ability of guppy fish (Poecilia reticulata) to receive high dietary doses of oxymetholone hormone and its effects on growth parameters, survival and reproduction, 300 fish at the age of 10 weeks, with an average weight of 0.38 ± 0.09 g were randomly assigned to 5 treatments and 3 replications in 15 glass aquaria (100 liters volume). Hormone levels were considered as 5 different dos...
The experiment was conducted to determine the effects of different photoperiods and darkness on the growth and survival of juvenile Catla catla in the laboratory for 90 days. Fishes were divided into four aquaria (10 fish per aquarium), and subjected to different photoperiod regimes of 8 hours light: 16 hours dark (8L:16D), 16 hours light: 8 hours dark (16L:8D), continuous light (24L:0D) and co...
Six different diets including two rainbow trout starters, Gammarus dry powder, shrimp dry powder, egg yolk dry powder and newly hatched Artemia were used in feeding of Caspian Kutum larvae. During a 4-week trial, larvae with a mean weight of 17.5 ± 4.7 mg were fed with three replicates and growth parameters were measured at the end of the experiment. Thirty fish in each experimental unit with...
Background Recent researches reveal that manual puncturing of the trophectoderm of blastocyst before vitrification, increase the quality of embryo. However, in any of these studies, the importance of blastocoelic fluid and its impact on the formation of three cell lines is not mentioned. Therefore, in the present study, the effect of blastocoelic fluid reduction before vitrification on survival...

One of the major issues in aquaculture is to keep balance between growth rate of fish and optimal use of consumed food. L-carnitine is considered an effective food supplement for fish growth. Sobaity seabream is one of the commercially important species in the Persian Gulf that is highly considered in aquaculture too. Growth indices and survival rate of 240 Sobaity fingerlings with mean weight ...
This study was accomplished to investigate the effect of Artemia urmiana nauplii enriched with Pediococcus acidilactici as probiotic on growth performance and survival rate of great sturgeon, Huso huso. Artemia nauplii were enriched with P. acidilactici at a final concentration of 1010 CFU mL-1 in three time dependent treatments as 3 h (T3), 6 h (T6), 9 h (T9), and one non-enriched Artemia as ...
Background:The incidence rate of head and neck cancer in the world is about 560,000 new cases a year. Larynx cancer is the most common malignancy in head and neck in Iran. The most common head and neck carcinoma is the malignancy of squamous epithelial cells. This study was conducted to determine the survival rate of patients undergoing nonsurgical treatment methods for larynge...
background: the classical supportive therapy for î² -thalassemia major consists of regular blood transfusion, iron-chelation therapy and specific treatment of the related complications. a balance between the maintenance of the highest possible level of haemoglobin and lowest possible level of iron accumulation in heart and liver give the best chance of survival and the best quality of life. met...
