Oxidative damage is an important mechanism in X-ray-induced cell death. Radiolysis of water molecules is a source of reactive oxygen species (ROS) that contribute to X-ray-induced cell death. In this study, we showed by ROS detection and a cell survival assay that NADPH oxidase has a very important role in X-ray-induced cell death. Under X-ray irradiation,(More)
Spermiogenesis is a complex and highly ordered spermatid differentiation process that requires reorganization of cellular structures. We have previously found that Atg7 is required for acrosome biogenesis. Here, we show that autophagy regulates the round and elongating spermatids. Specifically, we found that Atg7 is required for spermatozoa flagella(More)
The ectoplasmic specialization (ES) is essential for Sertoli-germ cell communication to support all phases of germ cell development and maturity. Its formation and remodeling requires rapid reorganization of the cytoskeleton. However, the molecular mechanism underlying the regulation of ES assembly is still largely unknown. Here, we show that Sertoli(More)
BACKGROUND Drought is the most important abiotic stress factor limiting corn (Zea mays L.) growth and productivity. Therefore efficient management of soil moisture and study of metabolic changes in response to drought are important for improved production of corn. The objective of the present study was to gain a better understanding of drought tolerance(More)
In this paper, we have fabricated two types vertical structure organic thin film transistors (VOTFT) by vacuum evaporation and magnetron sputtering, the semiconductor material are copper phthalocyanine (CuPc) and lead phthalocyanine (PbPc) which have good photosensitive properties. CuPc used in this work thermally evaporated at the temperature of 400(More)
Inorganic nanohybrid polyimide (PI) film has great potential for applications in the areas of electrics and electronics because of its excellent electrical performance, such as the resistance to aging and corona and so on. The breakdown strength of insulating materials is generally measured by DC, AC or impulse voltage. However, the influence of laser(More)
In order to make the operating characteristics of OFET device better, we used CuPc to fabricate organic thin film transistor with five layers structure of Au/ CuPc / Al / CuPc /Au with vertical conductive channel. Tested basic operating characteristics and analyzed relation between device structure and operating characteristics of it. The experimental(More)
