背景情况:
- 肝切除术后肝衰竭 (PHLF) 是肝切除后死亡的一个关键决定因素.
- 术后氧化应激在PHLF发展中的作用仍然不完全理解.
研究的目的:
- 为了前性地评估外科手术期间的氧化应激标志物及其与PHLF的关联,在首次对人体进行的研究中.
- 调查氧化应激标志物对PHLF和死亡率的预测潜力.
主要方法:
- 观察性试点研究评估血清标志物 (8-异质,4-HNE,抗氧化能力,维生素A/E) 和肝脏组织4-HNE/UCP2 IHC.
- 氧化应激标志物,已知的PHLF风险因素和临床结果之间的相关性分析.
- 包括52名接受肝切除的患者,其中69.2%有重大切除.
主要成果:
- PHLF发生在25%的患者中,与90天死亡率有显著联系.

264
Phase I biotransformation, or functionalization, is a crucial chemical process that converts drugs and other xenobiotics into more water-soluble forms, facilitating expulsion from the body. It involves oxidative, reductive, and hydrolytic reactions that add or unveil polar functional groups on lipophilic substrates. Key players in phase I reactions are the mixed-function oxidases. Situated in liver cell microsomes, these enzymes predominantly carry out drug metabolism. They require molecular...

12.1K
Peroxisomes are specialized organelles present in fungi, plant, and animal cells. It can vary in number, size, morphology, and activity depending on the type of tissue and the nutritional state of the cell. For example, cells with active lipid metabolism, such as adipocytes, neurons, and hepatocytes, have more peroxisomes than other cells in the body. Besides their primary role in breaking down complex organic molecules, peroxisomes can also synthesize specific macromolecules and participate in...
