概括
低囊泡单胺转运器2 (VMAT-2) 基因表达预测甲基胺使用障碍 (MUD),而高多巴胺转运器 (DAT) 基因表达预测烟草使用障碍 (TUD). 在MUD患者中,精神体验更高.
科学领域:
- 神经科学是一个神经科学.
- 遗传学 是一个遗传学.
- 精神病学是一个精神病学.
背景情况:
- 甲基胺使用障碍 (MUD) 与神经递质系统的改变有关.
- 多巴胺转运体 (DAT) 和膀单胺转运体2 (VMAT-2) 是单胺神经传递的关键调节体.
- 了解它们在MUD和相关的精神体验中的作用对于开发有针对性的干预措施至关重要.
研究的目的:
- 调查DAT和VMAT-2基因和蛋白质水平以及MUD患者的临床参数之间的关系.
- 与对照人群相比,评估MUD患者的精神体验和其他临床因素.
- 确定DAT和VMAT-2表达水平对MUD和烟草使用障碍 (TUD) 的诊断潜力.
主要方法:
- 一项涉及50名MUD男性和100名健康对照 (50名吸烟者,50名非吸烟者) 的病例对照研究.
- 使用社区心理经验评估 (CAPE) 尺度对心理经验的评估.
- 在血液样本中量化DAT和VMAT-2基因和蛋白质水平.
主要成果:
- 在MUD患者中,CAPE得分显著更高,表明更多的精神体验.
- 与对照组相比,在MUD患者中观察到较低的DAT蛋白和VMAT-2基因/蛋白水平.

Drug Abuse and Addiction: Pharmacological Phenomena
434
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Attention-Deficit/Hyperactivity Disorder
38
Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.
Diagnostic Criteria and Symptoms
To diagnose ADHD, symptoms must manifest before age 12 and be evident across multiple settings....

Phase II Reactions: Methylation Reactions
132
Methylation is a phase II biotransformation process involving the attachment of a methyl group to a substrate. Enzymes known as methyltransferases orchestrate this reaction.
The mechanism of methylation unfolds in two stages. The first stage sees a methyltransferase enzyme facilitating the transfer of a methyl group from S-adenosylmethionine (SAM) to the substrate, forming S-adenosylhomocysteine (SAH). The second stage involves further metabolism of SAH into homocysteine, which can be recycled...
