概括
与洛卡赛林和贝塔希斯联合治疗通过增强多巴胺基神经元活动,在不影响体重的情况下,在老鼠中逆转了与肥胖相关的认知缺陷. 这为肥胖引起的记忆障碍提供了潜在的治疗方法.
科学领域:
- 神经科学是一个神经科学.
- 药理学 药理学是指药理学的学科.
- 肥胖问题研究研究
背景情况:
- 肥胖会导致认知障碍,特别是在前额叶皮层 (PFC) 依赖的学习和记忆中.
- 组合药物治疗可以有效地解决肥胖引起的认知缺陷.
研究的目的:
- 评估洛卡塞林 (5-HT2C激动剂) 和贝塔希斯 (H1激动剂/H3抗剂) 组合疗法,用于逆转大鼠饮食引起的肥胖 (DIO) 认知缺陷.
- 为了研究这种组合对腹部体区域 (VTA) 多巴胺激应神经元活动的影响.
主要方法:
- 鼠被诱导使用DIO,并接受了洛卡赛林和贝塔希斯 (单独或结合) 治疗30天.
- 用Y迷宫,新型物体识别和物体在位 (OIP) 测试来评估认知功能.
- 在体内电生理学检查了VTA多巴胺基神经元活动.
主要成果:
- 肥胖大鼠在OIP任务中表现不佳,这表明PFC依赖的认知缺陷.
- 组合治疗显著改善了肥胖大鼠的OIP任务得分.
- 同时治疗增加了肥胖大鼠自发活跃的VTA多巴胺基神经元,但没有降低体重.
结论:
- 洛卡塞林-贝塔希斯联合治疗显示出扭转与肥胖相关的认知缺陷的潜力.
- 治疗效果可能由中皮层多巴胺激应神经元活动的增强介导.

Atherosclerosis III: Management
321
Management of atherosclerosis involves an integrated strategy encompassing pharmacological treatment, surgical interventions, lifestyle changes, and nutrition therapy to address the multifactorial nature of the disease.Pharmacological TherapyA cornerstone of atherosclerosis management is the use of pharmacological agents. Statins, such as atorvastatin, are pivotal in inhibiting HMG-CoA reductase, an enzyme that catalyzes an initial step in cholesterol synthesis in the liver. This reduction in...

Drugs for Treatment of Constipation-Predominant IBS
724
Pharmacological therapies for IBS-C are designed to alleviate abdominal discomfort and enhance bowel function. In patients with IBS-C, fiber supplements may help soften stools and decrease straining, but may also lead to increased gas production and bloating. Osmotic laxatives like milk of magnesia are frequently used to soften stools and increase stool frequency in IBS-C patients. In addition, two drugs approved for use in severe IBS-C adult cases are linaclotide (Linzess) and lubiprostone...
