Comparison of Expression of Growth Hormone-Releasing Hormone and Its Receptor Splice Variant 1 in Different Stages of Endometriosis

Evaluation of Morphological Changes in Muscle Fibers and Neuronal Terminals of Motor Neurons in Male Rats from Childhood to Old Age

Introduction: The aim of this study was to investigate the effect of time and age on morphological changes in male rats. Methods: For conducting this study, 15 male Wistar rats in three age groups of 2 weeks (150-100 g), 6 weeks (250-220 g) and 96 weeks (320-280 g) were kept in Pasargad Tissue and Gene Laboratory in Tehran City for six weeks and 48 hours later they were dissected and the soleu...

The Effect of Resistance-Aerobic Training on The Expression of Sema3a and NCAM Genes and Proteins in the Soleus Muscle of Male Rats of Different Age Groups

Objective: The aim of this study was to investigate the effect of resistance-aerobic training on the expression of Sema3a and NCAM genes and proteins of Soleus muscle in male rats of different age groups. Methods: Thirty male Wistar rats in three groups of 2-week-old infant (n = 10), young 6-week-old (n = 10) and 96-week-old elderly (n = 10) were divided into two groups of training and control...

FGFR1 inhibits skeletal muscle atrophy associated with hindlimb suspension

BACKGROUND Skeletal muscle atrophy can occur under many different conditions, including prolonged disuse or immobilization, cachexia, cushingoid conditions, secondary to surgery, or with advanced age. The mechanisms by which unloading of muscle is sensed and translated into signals controlling tissue reduction remains a major question in the field of musculoskeletal research. While the fibrobla...

Impact of Western and Mediterranean Diets and Vitamin D on Muscle Fibers of Sedentary Rats

BACKGROUND The metabolic syndrome is associated with sarcopenia. Decreased serum levels of Vitamin D (VitD) and insulin-like growth factor (IGF)-1 and their mutual relationship were also reported. We aimed to evaluate whether different dietary profiles, containing or not VitD, may exert different effects on muscle molecular morphology. METHODS Twenty-eight male rats were fed for 10 weeks in o...
