Lipid Nanoparticles Delivering ClpP‐mRNA Suppress Pyroptosis and Senescence in Intervertebral Disc Degeneration via mTOR/BNIP3‐Activated Mitophagy

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

Cost–benefit analysis of first‐trimester pre‐eclampsia screening: comparison of multivariable Gaussian algorithm with and without placental growth factor

Ultrasound in Obstetrics &Gynecology, Volume 67, Issue 2, Page 162-167, February 2026.
ABSTRACT Objective Pre‐eclampsia (PE) is a leading cause of maternal and neonatal morbidity and mortality worldwide. Early identification of high‐risk pregnancies in the first trimester allows preventive treatment with low‐dose aspirin. This study aimed to evaluate whether multivariable Gaussian algorithm‐based PE screening strategies, with and without

Negotiating Centralization: How Local Networks Reshaped Scotland's National Care Service Reform

Politics &Policy, Volume 54, Issue 1, February 2026.
ABSTRACT Centralizing reforms frequently diverge from their original designs, yet the processes through which this divergence occurs remain insufficiently understood. This article examines Scotland's National Care Service reform (2021–2025), a major recentralization that underwent significant modification following sustained engagement from local ...

Development of a Four‐Language Questionnaire to Investigate Environmental Risk Factors for the Development of Canine Atopic Dermatitis and to Monitor Disease Course and Progression

Veterinary Dermatology, Volume 37, Issue 1, Page 34-44, February 2026.
Background: The chronic and multifactorial character of canine atopic dermatitis (cAD) often leads to poor disease control and treatment dissatisfaction. Environmental factors are likely to contribute to the disease development and may play a more important role than assumed previously.

Preparation and characterization of chitosan and gelatin-siloxane nanoparticles as gene delivery system [PDF]

, 2006
基因治疗的提出为人类医学的发展提供了一种新的治疗手段。基因治疗载体是基因治疗中关键的因素之一。目前，基因治疗载体分为：病毒载体和非病毒载体。尽管病毒载体具有较高的转染效率，但易引起免疫反应和致癌作用；而非病毒载体如壳聚糖、明胶载体等具有良好生物相容性，但其粒径高达几百纳米至几个微米，不利于细胞对载体的摄取。因此，为了促进载体的细胞内化过程，本文旨在开发出粒径在100nm以下的新型壳聚糖、明胶-硅氧烷纳米颗粒，为基因治疗的发展提供新型的载体。本文的主要研究结果如下：1 ...

MDR1基因+3435C/T基因型单核苷酸多态性对硼替佐咪治疗的多发性骨髓瘤预后的影响

Zhongguo shiyan zhenduanxue, 2013
目的探讨MDR1基因+3435C/T的单核苷酸多态性对硼替佐咪治疗的多发性骨髓瘤患者预后的影响。方法采用DNA测序方法检测MDR1基因+3435C/T的单核苷酸多态性;应用Kaplan-Meier来确认MDR1基因+3435C/T的单核苷酸多态性对硼替佐咪治疗/未治疗患者生存率的影响。结果 52.8%（n=47）的多发性骨髓瘤患者MDR1+3435位点的基因型为C/T,其余多发性骨髓瘤患者MDR1+3435位点的基因型均为T/T。MDR1+3435C/T基因型的患者的平均生存期为43.3月,而MDR1 ...
