d-galactose induces pancreatic disorder along with aging mouse model. vitex agnus-castus (vac) has potential pancreatic protective effect. hence, this study was designed to evaluate the hypoglycemic and pancreas protective effects of vac hydroalcoholic extract in d-galactose-induced aging female mice. in the present experimental study, 72 adult female naval medical research institute (nmri) mic...

Introduction: Based on our previous findings, the treatment of stem cells alone or in combination with thyroid hormone (T3) and mild exercise could effectively reduce the risk of stroke damage in young mice. However, it is unclear whether this treatment is effective in aged or middle-aged mice. Therefore, this study designed to assess whether combination of Bone Marrow Stromal Cells (BMSCs) wit...

Objective(s): As a multifunctional molecule, NO has different effects on liver injury. The present work aimed to investigate the effects of Nos2 knockout (KO) on acute liver injury in aged mice treated with carbon tetrachloride (CCl4). Materials and Methods: The acute liver injury model was produced by CCl4 at 10 ml/kg body weight in 24-...

Background: Melatonin, the pineal gland hormone as a direct or indirect antioxidant and free radical scavenger, is involved in the process of both aging and age-related diseases. This study investigates the effects of melatonin on the histology of testicular seminiferous tubules in aged mice. Materials and Methods: Twenty male, white mice, aged 16 months, that weighed 20-23 gr were equally divi...

objective: patients over 60 years of age have higher mortality and morbidity after major liver resections. nitric oxide (no) derived from the catalytic activity of nos2 plays a beneficial role in liver regeneration (lr) after partial hepatectomy (ph). in this experiment, we evaluated the effect of nos2 knockout (ko) on lr in aged mice after ph. materials and methods: in this cohort study, 52 tw...

background and aims: the e2f family of transcription factors is encoded by at least eight genes, e2f1-8. these proteins are important targets of the retinoblastoma protein (rb) contributed in regulation of transcription, cell cycle and apoptosis. the aim of this study was to investigate the expression levels of e2f protein family including e2f1, e2f2, e2f7, e2f8 and rb1 in the lineage negative ...

background: to assess embryos derived by the transfer of meiosis-ii chromosomes (m-ii-t) from aged mice oocytes into ooplasms from younger mice to overcome the problem of age-related decline in female fertility. materials and methods: the developmental capacity karyotype and ultrastructure of reconstructed oocytes derived from meiosis-ii chromosome transplantation from aged mice into the ooplas...
