BACKGROUND One of the major challenges in currently chemotherapeutic theme is lacking effective biomarkers for drug response and sensitivity. Our current study focus on two promising biomarkers, ERCC1 (excision repair cross-complementing group 1) and BRCA1 (breast cancer susceptibility gene 1). To investigate their potential role in serving as biomarkers(More)
Functional recovery after transplantation of brain-derived neurotrophic factor (BDNF)-modified neural stem cells (NSCs) was evaluated in a rat model of cerebral ischaemia damage induced by temporary middle cerebral artery occlusion (tMCAO). Western blotting and enzyme-linked immunosorbent assay demonstrated upregulated BDNF protein expression by rat(More)
We found that an enriched environment (EE) could delay the loss of myelinated fibers in the white matter of rats during normal aging. However, the reasons for the protective effects of EE on the myelinated fibers were unclear. In this present study, via the use of stereological methods, we quantitatively investigated the myelin sheaths and the axons of(More)

— In this paper, we propose a multi(six)-port radio frequency (RF) front-end including both modulator and demodulator for impulse ultra-wideband (UWB) communication systems. This RF front-end validates full channel (3GHz-4GHz) uniform phase spectrum modulation scheme by using a six-port phase modulator and demodulator. Both the modulator and demodulator(More)
The Amur Grape (Vitis amurensis Rupr.) cultivars ’shuangFeng’ and ‘ZuoShanyi’ were grown in shelter greenhouse under natural sunlight and subjected to drought. Sap flow rate, net photosynthetic rate (P N), and chlorophyll (Chl) fluorescence were measured on Amur Grape leaves subjected to different drought treatments. Significant decreases in P N were(More)
Human angiotensinogen gene contains a C/A polymorphism at 20 bases upstream from the transcriptional initiation site. This sequence binds to the estrogen receptor when nucleoside A is present at this site and reporter constructs containing human angiotensinogen gene promoter with nucleoside A at -20 are transactivated on co-transfection of estrogen receptor(More)
The oxidative processes and antioxidative system in cucumber (Cucumis sativus L.) fruit were determined during development and senescence. Four distinct developmental stages could be delineated during fruit maturation: immature (3–8 d after anthesis, DAA), mature (9–16 DAA), breaker (17–22 DAA), and yellow (35–40 DAA). The electrolyte leakage,(More)
This paper presents a method, which simultaneously estimates the electrical conductivity and magnetic permeability of porous metals. Porous Cu and Fe manufactured by the lost carbonate sintering process have been tested. An air-cored solenoid coil was designed for the measurements of rod-shaped samples when inserted coaxially with the coil. It was(More)
Plant microRNAs (miRNAs) play important roles in regulating plant growth, development, and responses to abiotic stresses. In this study, 38 miRNAs (TaMIRs) from wheat (Triticum aestivum L.), 36 from the miRBase database, and two from our previous work were characterized and subjected to an expression pattern analysis under normal conditions and a drought(More)
