An Improved Method for Collection of Cerebrospinal Fluid from Anesthetized Mice06:40

An Improved Method for Collection of Cerebrospinal Fluid from Anesthetized Mice

65.9K
This protocol describes an improved technique for the abundant collection of cerebrospinal fluid (CSF) with no contamination from blood. With greater sample collection and purity, more analyses can be performed using CSF to further our understanding of diseases that affect the brain and spinal...

Treating SCA1 Mice with Water-Soluble Compounds to Non-Specifically Boost Mitochondrial Function

11.1K
We present a biochemical and behavioral protocol to evaluate the efficacy of mitochondria-targeted water-soluble compounds for the treatment of Spinocerebellar ataxia type 1 (SCA1) and other cerebellar neurodegenerative diseases.

Intracerebroventricular and Intravascular Injection of Viral Particles and Fluorescent Microbeads into the Neonatal Brain05:51

Intracerebroventricular and Intravascular Injection of Viral Particles and Fluorescent Microbeads into the Neonatal Brain

20.3K
Here, we describe a simple method of intracerebroventricular and intravascular injection of viral particles or fluorescent microbeads into the neonatal mouse brain. The localization pattern of the virus and nanoparticles could be detected by microscopic evaluation or by in situ hybridization.

A Rapid and Specific Microplate Assay for the Determination of Intra- and Extracellular Ascorbate in Cultured Cells11:56

A Rapid and Specific Microplate Assay for the Determination of Intra- and Extracellular Ascorbate in Cultured Cells

13.9K
Ascorbate plays numerous important roles in cellular metabolism, many of which have only come to light in recent years. Here we describe a medium-throughput, specific and inexpensive microplate assay for the determination of both intra- and extracellular ascorbate in cell culture.

Direct Intraventricular Delivery of Drugs to the Rodent Central Nervous System14:55

Direct Intraventricular Delivery of Drugs to the Rodent Central Nervous System

61.6K
We describe a method to target drugs to the central nervous system by either implanting a catheter or performing a bolus injection into the right lateral ventricle in mice. We focus specifically on the delivery of antisense oligonucleotides. This technique is readily adaptable to other drugs and to...

科学领域:

  • 内分泌学 在内分泌学.
  • 代谢障碍 代谢障碍 代谢障碍
  • 心血管疾病研究研究

背景情况:

  • 血糖障碍是心血管疾病的主要危险因素.
  • 氧化应激是一种已知的并发症,与血糖障碍相关.

研究的目的:

  • 为了区分慢性高血糖与急性葡萄糖波动对2型糖尿病中氧化应激的影响.
  • 确定与氧化应激标志物相关的特定血糖控制参数.

主要方法:

  • 一项病例控制研究比较了21名2型糖尿病患者和21名健康对照.
  • 氧化应激通过24小时的尿液8-异位前列腺素F2alpha (8-异位PGF2alpha) 排泄来测量.
  • 使用连续血糖监测 (血糖游览的平均幅度 - MAGE) 和食后血糖增加 (AUCpp) 来评估葡萄糖波动.

主要成果:

  • 患有2型糖尿病的患者表现出比对照人群更高的尿路8-异位PGF2α分泌量.
  • MAGE和AUCpp都与氧化应激标志物有显著的相关性.
  • 葡萄糖波动 (MAGE和AUCpp) 与氧化应激比长期血糖控制标志物 (如HbA1c) 更强烈相关.

结论:

  • 急性葡萄糖波动,特别是食后波动,在引发氧化应激方面比持续的高血糖症发挥更重要的作用.
  • 2型糖尿病的治疗策略应该集中在管理急性葡萄糖波动,除了整体血糖控制 (HbA1c).
