Background and purpose: Chronic stress has detrimental effects on reproductive system. Offspring are likely to be vulnerable to adverse effects from antipsychotic medication and stress transmitted through gonads and gametes. The present study aimed to investigate the fertility of female rats from male rats treated with sulpiride because of chronic physical or psychological stress. Materials a...
This research was designed to study sexual differences in place conditioning induced by morphine in offspring born of female Wistar rats mated with drug-naïve males. Mothers were exposed to morphine during the 14th-16th days of gestational. Control dams were simply saline-injected. Female and male virgin offspring born of morphine-treated or saline-treated mothers were separately housed until b...
Background and purpose: Valproic acid derivatives are histone deacetylases (HDACs) inhibitors. HDACs are important in epigenetic processes. Some epigenetic modifications are inherited. This study aimed at investigating the intergenerational effects of pre-pregnancy chronic valproate consumption on offspring. Materials and methods: In this experimental study, twelve female Wistar rats were rand...
background the hippocampus is responsible for memory. a diet full of antioxidants improves brain damage and cognitive function. regard the antioxidant effects of zingiber officinalis (ginger) and its flavonoids components. objectives the aim of this study was to evaluate the effect of the extract of ginger on memory by using hippocampus tissue of the male offspring of rats. materials and method...
objective: maternal type and amounts of dietary fatty acids affect on reproductive process in the mice. the present study investigated the effects of maternal supplementation with different amounts of omega-6 or omega-9 during pregnancy on the number of offspring, sex-ratio and duration of gestation. materials and methods: eight-week-old female c57bl/6 mice were randomly assigned into four diet...
this study was conducted to evaluate the effects of maternal diabetes on fetal spinal structure, especiallyin brachial enlargement. sixteen adult female rats were divided into two groups. diabetes was induced in one group by alloxan agent. both groups became pregnant by natural matting. on days 7, 14, 21 and 28 after birth, the brachial enlargement of the spinal cord was collected from offsprin...
This paper shows a new algorithm to calculate the mean and temperature of multi-branch combinatorial games. The algorithm gradually, one node at a time, expands the offspring of a game. After each step of expansion, the lower and upper bounds of the mean and temperature of the game is re-calculated. As the expanding process continues, the range between the lower and upper bounds is narrowed. Th...
Consider a Galton-Watson process with immigration. The limiting distributions of the non-sequential estimators of the offspring mean have been proved to be drastically different for the critical case and subcritical and supercritical cases. A sequential estimator, proposed by Sriram, Basawa and Huggins (1991), was shown to be asymptotically normal for both the subcritical and critical cases. Ba...
Recent studies indicate that environment can modify skeletal muscle gene expression and transcriptional factors in offspring genes. Therefore, exercising can lead to changes in the gene expression of the future generations. One of the important metabolic factors is PDK4, which is known as the main factor in Pyruvate Dehydrogenase Complex (PDC). This study examined the effects of maternal exerci...
The objective of this study was to evaluate the imputation accuracy of parent-offspring trios under different scenarios. By using simulated datasets, the performance Bayesian LASSO in genomic prediction was also examined. The genome consisted of 5 chromosomes and each chromosome was set as 1 Morgan length. The number of SNPs per chromosome was 10000. One hundred QTLs were randomly distributed a...
