Background: Soil and plant contamination in copper exposure causes chronic copper poisoning (CCP) in animals following the consumption of plants in these soils. Objectives: The present study was carried out on 10 clinically affected copper poisoned cases (in each season) from autumn 2015 to the end of summer 2016, in four seasons in Kerman province to evaluate the seasonal effects of CCP in she...

The present study was carried out in 2011 to measure concentration of heavy metals chromium and tin in liver and muscle tissue of Liza aurata (golden grey mullet) in estuaries of the rivers Babolroud, Tajan and Gorganroud. Accordingly, after sampling the target are asandisolating muscle (18samples) and liver (18samples) tissues, they were digested and analyzed using Graphite Furnace Atomic Abso...

YKL-40 (YKL for the first three N-terminal residues of a 40 kDa protein) belongs to a group of human chitinase-like proteins (CLPs), which are similar to chitinases but lack chitinolytic activity. YKL-40 mRNA and its protein levels have been reported elevated in multiple disorders including asthma, cystic fibrosis, rheumatoid arthritis and malignant tumors. Here, we quantified the YKL-40 mRNA l...

Background: Methotrexate (MTX) is an anti-metabolite drug used in the treatment of many cancers and autoimmune diseases. Methods: This study investigated the protective effect of flaxseed oil, sesame seed oil, and their mixture on the MTX-induced hepatorenal toxicity. Thirty rats divided into five groups of: normal control, MTX control, and flaxseed oil, sesame seed oil, and the mixture groups...

background: ovarian tissue transplantation is emerging technologies for fertility preservation. in addition, in vitro maturation (ivm) of oocytes retrieved from ovarian tissues may overcome the fertility defects in certain cases. objective: the aim was to evaluate the best site for ovarian tissue transplantation in mice. also, feasibility of ivm of oocytes retrieved from auto grafted ovarian ti...

Background: Naringin is a major antioxidant in Citrus fruits and herbs. To clarify molecular forms distributed to various tissues, we investigated tissue distribution of naringin and relevant metabolites in rats after repeated dosing. Methods: Male Sprague-Dawley rats were orally administered naringin (210 mg/kg) twice daily for eight days. At 6 h post the 17th dose, various tissues including l...

Lineage-specific transcription factors (TFs) display instructive roles in directly reprogramming adult cells into alternate developmental fates, in a process known as transdifferentiation. The present study analyses the hypothesis that despite being fast, transdifferentiation does not occur in one step but is rather a consecutive and hierarchical process. Using ectopic expression of Pdx1 in hum...
