Rare Metals, Volume 45, Issue 2, February 2026.ABSTRACT Intervertebral disc degeneration (IDD) is a predominant cause of low back pain, significantly impacting quality of life. Mitochondrial fitness is essential in the progression of IDD, as it regulates cellular senescence and pyroptosis. This study investigates the role of mitochondrial caseinolytic protease P (ClpP) in alleviating senescence and

血清免疫固定电泳、蛋白电泳、免疫球蛋白及轻链定量对多发性骨髓瘤临床诊断价值探讨
Zhongguo shiyan zhenduanxue, 2010 目的探讨血清蛋白电泳、总蛋白、免疫球蛋白及轻链、蛋白电泳、免疫固定电泳测定对多发性骨髓瘤（MM）的诊断价值。方法对89例多发性骨髓瘤患者的血清总蛋白、免疫球蛋白及轻链、蛋白电泳、免疫固定电泳和尿轻链κ、λ的检测结果进行统计分析。结果 89例MM患者38例患者血清总蛋白含量升高;55例免疫球蛋白及轻链定量显著升高;血清蛋白电泳56例检出M带,而免疫固定电泳中89例均为阳性结果。结论免疫固定电泳检是MM诊断的敏感方法 ,应作为MM的常规检测方法 。

SWEET1‐mediated glucose transport is crucial for energy availability in Arabidopsis
New Phytologist, Volume 249, Issue 4, Page 1816-1830, February 2026.Summary The stress‐responsive hormone abscisic acid (ABA) is known for its inhibitory effects on various physiological processes, including seed germination, often resulting in energy deprivation. Interestingly, ABA‐induced germination inhibition can be alleviated by exogenous glucose (Glc), mimicking a functional interplay between ABA and sugar ...

Journal of Neurochemistry, Volume 170, Issue 1, January 2026.In the nucleus accumbens (NAc), a heparan sulfate endosulfatase Sulf1 is expressed in both dopamine D1 receptor (Drd1) expressing and Drd2‐expressing medium spiny neurons (D1‐MSNs and D2‐MSNs, respectively). Sulf1 knockout (KO) mice showed impairment in both the cocaine‐induced conditioned place preference (CPP) test and inhibitory avoidance (IA) test.
