| 1 | THz spectra of five borates crystals显示文摘Terahertz spectral responses have been studied for five borate crystals Na5[B2P3O13] (NBP), Zn3BPO (ZBP), SrB4O7 (SBO), Na3La9O3(BO 3)8 (NLBO) and PbB4O7 (PBO). It is found that the samples had good transmission in 0.25―1.5 THz region. Both SBO and NLBO have an absorption coefficient less than 10 cm1. Among them, SBO has not only the smallest absorption coefficient but also a very flat dispersion in the frequency region under investigation. Distinct resonance absorption peaks are observed for ZBP at ν1 = 1.4 THz, ν2 = 2.0 THz and SBO at ν = 2.4 THz. In the spectrum of PBO, two abnormal dispersions appear in the frequency regions 1.44―1.74 and 2.2―2.5 THz. The absorption coefficients and refraction indices of the five crystals are extracted from the THz time-domain (THz-TDS) spectra in 0.25―2.5 THz region. The properties and origins of the spectral responses are addressed. | HOU BiHui WANG YaLi WU YiCheng CHEN Hua WANG Li FU PengZhen LIU FengYan | 2008 | Chinese Science Bulletin2008，53，1： | 2 |
| 2 | A kidney-brain neural circuit drives progressive kidney damage and heart failure显示文摘Chronic kidney disease(CKD)and heart failure(HF)are highly prevalent,aggravate each other,and account for substantial mortality.However,the mechanisms underlying cardiorenal interaction and the role of kidney afferent nerves and their precise central pathway remain limited.Here,we combined virus tracing techniques with optogenetic techniques to map a polysynaptic central pathway linking kidney afferent nerves to subfornical organ(SFO)and thereby to paraventricular nucleus(PVN)and rostral ventrolateral medulla that modulates sympathetic outflow.This kidney-brain neural circuit was overactivated in mouse models of CKD or HF and subsequently enhanced the sympathetic discharge to both the kidney and the heart in each model.Interruption of the pathway by kidney deafferentation,selective deletion of angiotensin II type 1a receptor(AT1a)in SFO,or optogenetic silence of the kidney-SFO or SFO-PVN projection decreased the sympathetic discharge and lessened structural damage and dysfunction of both kidney and heart in models of CKD and HF.Thus,kidney afferent nerves activate a kidney-brain neural circuit in CKD and HF that drives the sympathetic nervous system to accelerate disease progression in both organs.These results demonstrate the crucial role of kidney afferent nerves and their central connections in engaging cardiorenal interactions under both physiological and disease conditions.This suggests novel therapies for CKD or HF targeting this kidney-brain neural circuit. | Wei Cao Zhichen Yang Xiaoting Liu Siqiang Ren Huanjuan Su Bihui Yang Youhua Liu Christopher S.Wilcox Fan Fan Hou | 2023 | Signal Transduction and Targeted Therapy2023，8，6： | 0 |
| 3 | Superconducting State Volume in High T_(c) Superconductor and Non-resonant Microwave Absorption显示文摘The mechanism of low-field non-resonant microwave absorption is speculated,and it is exposed that the magnitude of the microwave signal indicates the superconducting state volume in the shell lying along inner surface of the sample. | HOU Bihui WANG Zhizhong | 1992 | Chinese Physics Letters1992，9，3： | 0 |
