The present study aims at investigating muscle development and stress response in early stages of Siberian sturgeon when subjected to different rearing temperatures, by analysing growth and development of the muscle and by assessing the stress response of yolk-sac larvae. Siberian sturgeon larvae were reared at 16°C, 19°C and 22°C until the yolk-sac was completely absorbed. Sampling timepoints ...

Trabecular bone is routinely analysed by histomorphological-histometrical and immunohistochemical techniques as means of assessing the differentiation status of bone deposition and growth. Currently few embedding resins exist for which both morphological and immunohistochemical analyses can be performed on mineralised tissue. Paraffin, the standard embedding medium for bone enzyme and immunohis...

background: fluoride (f−) is a trace element that is incorporated into bone mineral during bone formation. this study assessed the effect of increasing fluoride doses on the bone formation and microarchitecture on the femur of rats by histological, and histometrical methods. materials and methods: a total of 16 rats was divided into one group of control and three groups of animals that received...

BACKGROUND: There is not enough information about theeffects of heat stress and photoperiod on different lobes structure.OBJECTIVES: The present study aims at determining thehistological changes and the rate of changes in each lobes of ratprostate, affected by photoperiod changes and heat stress.METHODS:To this end, 15 adult male wistar rats were divided tothree groups: 1. the control group in ...

Abstract Background Polycystic ovary syndrome (PCOS) is the most common complex endocrine disorder affecting approximately 2–20% of reproductive aged females. Tumour Treating Fields (100–300 kHz) a recent innovative, non-invasive therapeutic approach to cancer therapy. This frequency as an alternative therapy for management polycystic ovaries has not yet been explored. Objectives To explore eff...

PURPOSE A case control study was conducted to assess the effects of long-term ingestion of Topiramate on fertility, body and reproductive organ weight and level of sex hormones in Sprague-Dawley male rats. METHODS Ten adult male rats were exposed to Topiramate diets at a concentration of 100 mg /kg for 60 days. Another ten control male rats received vehicle (distilled water). After 24 hours o...

Cirrhotic nodules were assumed to be a mixture of ellipsoids of different sizes and eccentricities, and mathematical derivations were discussed to estimate the distribution, the mean and the standard deviation of their sizes with only a small number of random histological sections. Logarithms of the largest axes of nodules approximately formed a normal distribution. With intermediate results, t...
