background: damage to spermatogenic and fertility disorders are among major side effects of chemotography drugs such as busulfan. to reduce the side effects of these drugs different methods such as protecting and fixing germinal cell epithelium, while employing chemotherapy are used. the aim of this study was to investigate the effect of exogenous melatonin on the treatment of oligospermic in s...

The present study appraised the hepatoprotective activity of aqueous extract of Camellia sinensis leaves and its possible mechanism of action against carbon-tetrachloride-induced liver damage. Liver damage was induced by   intraperitoneal administration of equal mixture of carbon tetrachloride   and olive oil (50 % v/v, 0.5 ml/kg ) in male Wistar rats (150-220g) once daily for...

The ablation of afferent input results in the reorganization of sensory and motor cortices. In the primary visual cortex (V1), binocular retinal lesions deprive a corresponding cortical region [lesion projection zone (LPZ)] of visual input. Nevertheless, neurons in the LPZ regain responsiveness by shifting their receptive fields (RFs) outside the retinal lesions; this re-emergence of neural act...

To understand the seismic damage characteristics of bottom frame-wall buildings and to study their seismic performance, the seismic damage outcomes of  bottom frame-wall structures in Du jiang weir by the Wen chuan earthquake on May 12,2008, China were field observed and studied. The assesment of the seismic damage to the bottom frame-wall masonry in Du jiang weir urban showed that the damage t...

Damage assessment is one of the crucial topics in the operation of structures. Multiplicities of structural elements and joints are the main challenges about damage assessment of space structure. Vibration-based damage evaluation seems to be effective and useful for application in industrial conditions and the low-cost. A method is presented to detect and assess structural damages from changes ...

In order to understand the seismic performance and mechanism of bottom frame seismic wall masonry structure (BFSWMS) and its vulnerability in empirical seismic damage, based on the statistical and numerical analysis of the field seismic damage observation data of 2178 Dujiangyan structures in the Wenchuan great earthquake urban of China on May 12, 2008, a non-linear function model between the s...
