- 老年学是一门学科.
- 神经科学是一个神经科学.
- 生物化学 生物化学
背景情况:
- 衰老的特点是恒温的下降,氧化应激是显著的贡献因素.
- 氧化应激标志物,如甲 (MDA) 和总醇水平,在衰老过程中发生变化.
- 像AST和ALT这样的肝酶也可能受到衰老和氧化应激的影响.
研究的目的:
- 为了研究天然基烯 (sesquiterpene) 类物质cedrol对老老鼠记忆力和氧化应激的影响.
- 为了评估cedrol对马隆迪阿尔海 (MDA) 和海马体,皮质,肝脏,心脏和脏的总醇水平的影响.
- 评估cedrol对老老鼠肝酶 (AST和ALT) 的影响.
主要方法:
- 年长的老鼠 (20个月大) 服用了cedrol (10毫克/公斤或5毫克/公斤) 或盐水30天.
- 通过在治疗的最后三天使用被动回避测试来评估记忆功能.
- 在各种组织中测量了氧化应激和肝酶的生化标志物.
主要成果:

01:30Cognitive Development During Adulthood
296
Cognitive development continues throughout adulthood, undergoing significant shifts across early, middle, and late stages. Individual transition occurs from adolescent idealism to pragmatic and adaptable thinking in early adulthood. During this period, individuals learn to integrate personal beliefs with the recognition that other perspectives are equally valid. Exposure to the complexities of modern society, diverse experiences, and higher education contribute to this adaptive thought process,...

01:30Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
213
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.
