Effects of Cinacalcet HCl on Secondary Hyperparathyroidism and Renal Injury in the Uremic Rat [PDF]

open access: yes, 2016
目的 慢性肾脏病患者随着肾脏功能的逐渐减退,早期即可出现钙磷失衡、维生素D缺乏、甲状旁腺激素以及成纤维生长因子FGF23的升高,而这种矿物质代谢紊乱又可促使患者出现继发性甲状旁腺功能亢进以及加重肾脏损伤。目前CaSR激动剂作为有效抑制甲状旁腺增生的临床药物,适用于已发生SHPT的透析患者,为探究其是否也能防治继发性甲状旁腺亢进、矿物质代谢紊乱及肾脏损伤,本研究通过5/6肾大部切除术结合高磷饮食建立尿毒症大鼠模型,分别在造模成功早期预防性给予大鼠西那卡塞干预以及在大鼠慢性肾衰确立后给予盐酸西那卡塞干预 ...

Laser‐Driven Halide Exchange and High‐Resolution Multicolor Patterning of Perovskite Films

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Translating the excellent properties of metal halide perovskites (MHPs) into practical flexible optoelectronic devices requires high‐resolution multicolor patterning techniques that are compatible with post‐fabrication processing. However, such a capability has remained elusive.

Broad‐Spectral Response Lead Halide Perovskite Solar Cells Through Integration of Multifunctional Organic Bulk‐Heterojunction and Quantum‐Cutting Downconversion Materials

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Expanding near‐infrared (NIR) spectral response and utilizing ultraviolet (UV) photons are effective strategies for enhancing the power conversion efficiency (PCE) of lead halide perovskite solar cells (PSCs). However, the range of NIR spectral response extension and the utilization of UV light for devices are not enough, and the loss of ...

The effects of miR-30c-1-3p regulating group ⅡA secretory phospholipase A2(sPLA2-ⅡA)expression on the pathogenic mechanism of atherosclerosis [PDF]

open access: yes, 2015
动脉粥样硬化(Atherosclerosis,AS)是急性冠脉综合症、脑卒中等众多心脑血管疾病共同的病理基础。sPLA2-ⅡA在动脉粥样硬化病变处含量明显增多、活性显著增强,同时伴随中性粒细胞的增多。sPLA2-ⅡA以酶的催化水解作用和作为致炎因子的促炎症反应双重生物学作用参与AS发生发展的各个阶段。 MicroRNA(miRNA)是近年发现广泛存在于真核细胞中的高度保守的、非编码单链小分子RNA,具有最广泛的基因调节功能,参与机体多种生理、病理过程的调控。 我们运用miRNA靶基因预测软件发现miR ...

A Multifunctional Reducing Molecular Dopant for 16% Efficient Tin Perovskite Solar Cells

open access: yesRare Metals, Volume 45, Issue 3, March 2026.
ABSTRACT Although lead‐based photovoltaics have seen remarkable progress, tin‐based perovskite solar cells (Sn‐PSCs) continue to face challenges due to their limited power conversion efficiency and insufficient operational stability. The primary cause of this performance gap is the susceptibility of Sn2+ to oxidation, which promotes rapid defect ...

Toxic effect of carbon dioxide and water soluble fractions of crude oil on marine madaka’s reproductive system [PDF]

open access: yes, 2016
海洋酸化和原油污染对海洋鱼类的影响时有报道,但海洋酸化和原油污染及两者联合暴露对海洋鱼类生殖系统的影响却鲜见报道。本实验以黑点青鳉为实验动物模型,分别采用原油组(500μg/LWSF)、酸化组(1500ppmCO2)和混合暴露组(1500ppmCO2+500μg/LWSF)对黑点青鳉从受精卵开始暴露,探究海洋酸化和原油污染对海洋鱼类的生殖系统的毒性作用及可能机制,结果如下: 原油水溶性成分和二氧化碳暴露的雄鱼表现出精细胞的成熟延迟,并且精原细胞的分裂和分化都受到影响;雌鱼则表现出卵细胞的成熟加速 ...
