Recordings from echolocating bat brains have for the first time given researchers a view into how mammals understand 3-D space.By training bats to fly around obstacles in a room, and sit patiently on ...
We have assembled the largest sample of ultra hard X-ray selected (14-195 keV) AGN with host galaxy optical data to date, with 185 nearby (z<0.05), moderate luminosity AGN from the Swift BAT sample. T...
We report on the spectral cross-calibration results of the Konus-Wind, the Suzaku/WAM, and the Swift/BAT instruments using simultaneously observed gamma-ray bursts (GRBs). This is the first attempt to...
Obscured AGN are fundamental to understand the history of Super Massive Black Hole growth and their influence on galaxy formation. However, the Compton-thick AGN (NH>1e24 cm^-2) population is basicall...
The karyotypes of 2 bat species from Iran were examined. The diploid number of chromosomes (2n) and the fundamental numbers of chromosomal arms (NFa) were determined to be 2n = 44 and NFa = 54 for Myo...

摘要:本文研究了高寒草甸生态系统中两种非冬眠草食性哺乳动物一一高原鼠兔和根母鼠的褐色脂肪组织(BAT)的重量和显微结构的季节性变化,结果表明严寒季节BAT增多,BAT细胞中的脂肪滴小而多、线粒体增大及嵴数目增多,温暖季节较低,这些变化与产热需要有关。
摘要:长爪沙鼠侧脑室注射促肾上腺皮质激素释放激素(CRH) 8μg 或CRH受体阻断剂2.5μg 后, 4 ±1 ℃暴露3 h ,对照组注射等体积生理盐水并置于24 ±2 ℃或4 ±1 ℃下。与常温对照组相比, 低温对照组褐色脂肪组织(BAT) 重量下降, BAT中解偶联蛋白(UCP1) mRNA 上调; 下丘脑促甲状腺激素释放激素(TRH) 含量降低, 血清T3 、T4 、T3/T4水平及BAT...
The diversity and conservation of bats in Jordan were reviewed based on field work and specimen collections. The bat fauna of Jordan consist of 24 species. Zoogeographical affinities of the bats of Jo...
This study is based on the records of gestation and lactation periods of 17 bat species (Rousettus aegyptiacus, Rhinolophus ferrumequinum, R. hipposideros, R. euryale, R. blasii, Myotis myotis, M. bly...
