[Wuziyanzong compound relieves oxidative stress injury and inhibits the apoptosis of Sertoli cells].

Objective: To investigate the effects of Wuziyanzong Compound on oxidative stress injury and the apoptosis of Sertoli cells.

Methods: We added H2O2 (100 mmol/L) and Wuziyanzong extract to the culture solution of TM4 cells, which were divided into a control, a model and three Wuziyanzong groups (low dose: 0.2 mg/ml, medium dose: 1 mg/ml, and high dose: 5 mg/ml).

[Application of near-infrared spectrum technology to research of weathering of red sandstone relics].

In the present paper, with near infrared spectroscopy technology, the weathering mechanism of red sandstone relics was studied. Six groups of red sandstone samples were analyzed using near infrared spectroscopy technology. The results show that the near-infrared spectroscopy technology can analyze the material composition of red sandstone before and after weathering, aiming to explore their components changed.

Opposite roles of MRF4 and MyoD in cell proliferation and myogenic differentiation.

The basic helix-loop-helix myogenic regulatory factors play critical roles in skeletal myogenesis. Among the myogenic regulatory factors (MRFs), MRF4 shows a biphasic expression pattern during the formation of myotomes, although its function remains unclear. In this study, we used BEF (spontaneously immortalized bovine embryonic fibroblast that shows myogenic differentiation by overexpression of MyoD) and C2C12 cells to investigate the function of MRF4.
