对家禽呼吸道疾病的诊断通常进行病毒分离或抗原检测,这种检测一般不能确诊。为了能够从临床呼吸道样本中同时检测多个病毒,本研究使用了RT-PCR法直接进行快速检测。

Objective To investigate the possible protective role of melatonin on the proliferative activity, and apoptosis of germ cells in chemotherapy-induced spermiotoxicity. Methods Male adult NMRI mice were divided into four groups. Then each group was divided into two subgroups of a and b. Group A （control）： mice received vehicle （1% ethanol）for 5 d. Group B （busulfan）： mice received a single dose of 20 mg/kg busulfan. Group C （melatonin）： mice received melatonin （10 mg/kg） for 5 d. Group D （busulfan＋melatonin）： mice received a 5-day course of melatonin （10 mg/kg） following an initial dose of busulfan （20 mg/kg）. Evaluations were made using bromodeoxyuridine （BrdU） labeling and in situ TUNEL assay after 5 d （subgroup a） or 35 d （subgroup b）. Results Busulfan-treated mice both in subgroups a and b, showed a significant increase in the number of apoptotic cells （P〈0.01） and decrease in BrdU labeling index （P〈0.01） compared with controls. Melatonin in group C significantly decreased BrdU labeling index compared with the control （P〈0.01）. Melatonin in group D significantly reduced apoptosis rate and increased BrdU labeling index compared with group B. Conclusion Melatonin may have a protective effect against busulfan-induced testicular damage, partly by decreasing of apoptosis and alteration in proliferative activity of germ cells.

聚合物材料,也就是通常说的塑料,由于其独特的性能,使其成为热绝缘体的绝佳材料。近年来的研究表明,聚合物具有较高的导热性,但其传输机制仍然未知。在本文中作者发明了一种具有62Wm^-1K^-1高导热性的聚乙烯薄膜,比普通聚合物的导热性(-0.1Wm^-1K^-1)大两个数量级,甚至超过许多常见的金属和陶瓷。结构研究和热模拟实验表明,这种薄膜由具有晶态和非晶态区域的纳米纤维组成,非晶态区域具有非常高(>16Wm^-1K^-1)的导热系数。作者的这项研究成果为具有重量轻、耐用、柔韧、耐腐蚀、易于加工等优势的高导热聚合物的设计和合成奠定了基础。
