概括
肠道微生物群影响良性发性 (BPV) 和中央 (VC) 风险,代谢和心理因素如抑郁症和肥胖症作为关键调解者. 准肠道健康可能会提供新的治疗策略.
科学领域:
- 微生物组研究 微生物组研究
- 神经科学是一个神经科学.
- 代谢健康 代谢健康
背景情况:
- 肠道微生物群和前置系统疾病之间的复杂联系,特别是良性发性 (BPV) 和中央 (VC),尚未得到充分理解.
- 现有研究尚未完全阐明将特定肠道细菌与BPV和VC的发展联系起来的潜在因果途径.
研究的目的:
- 调查肠道微生物群组成与发展BPV和VC的风险之间的因果关系.
- 探索肠道微生物群 - 头轴中的代谢 (HbA1c,肥胖症),炎症 (互白素-18) 和心理 (严重抑郁症) 因素的调解作用.
主要方法:
- 采用双向的双样本门德尔随机化 (MR) 方法,在遗传预测的肠道微生物特征和之间建立因果关系.
- 利用网络MR评估关键代谢,炎症和心理因素的调解效应,从像MiBioGen.Gen.这样的大规模联盟中获取数据.
主要成果:
- 确定了与BPV和VC风险相关的独特肠道微生物种群. 对于BPV,十种类型表现出影响,其中一些增加了风险,另一些降低了风险 (ORs 0.693-0.930).
- 对于VC,有八种类型被涉及,其中五种增加风险 (ORs 1.229-2.179) 和三种降低风险 (ORs 0.445-0.792).
- 调解分析揭示了严重抑郁症,肥胖症和HbA1c在BPV中的重要作用,以及VC中的互白素-18水平和严重抑郁症,突出了特定的调解途径.
结论:
- 这项研究提供了特定肠道微生物群组成与BPV和VC病变发生之间的潜在因果关系的证据.
- 代谢和心理因素显著调解了肠道微生物群和头之间的关系,表明复杂的相互连接的途径.
- 针对肠道微生物群和相关的代谢/心理途径,为管理而提供了一个有希望的治疗途径.

Equilibrium and Balance
4.6K
The inner ear assumes dual functionalities of auditory perception and equilibrium maintenance. The vestibule is the organ responsible for balance. This organ contains mechanoreceptors, specifically hair cells, endowed with stereocilia, which aid in deciphering information regarding the position and motion of our heads. Two intrinsic components, the utricle and saccule, help perceive head position, while the semicircular canals track head movement. Neurological messages initiated in the...

Pathophysiology of Vomiting
347
Vomiting is a complex physiological response to expel harmful or irritating substances from the body. It's a defensive mechanism triggered by stimuli like poisons, microbial toxins, cytotoxic drugs, and mechanical abdominal distension. The process is centrally coordinated by the vomiting (or emetic) center located in the medulla of the brainstem. This area, rich in muscarinic M1, histamine H1, neurokinin 1 (NK1), and serotonin 5-HT3 receptors, coordinates the act of vomiting through...

What is Monogastric Digestion?
70.9K
The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Anatomy of the Intestines
71.6K
Although digestion of proteins, carbohydrates, and lipids may begin in the stomach, it is completed in the intestine. The absorption of nutrients, water, and electrolytes from food and drink also occurs in the intestine. The intestines can be divided into two structurally distinct organs—the small and large intestines.
Small Intestines
The small intestine is an ~7 meter-long tube with an inner diameter of just 2.5 cm. Since most nutrients are absorbed here, the inner lining of the...

Irritable Bowel Syndrome I: Introduction
263
Irritable Bowel Syndrome (IBS) is characterized by functional disturbances in the gastrointestinal system, presenting a cluster of symptoms without evident structural or biochemical abnormalities. It primarily affects the large intestine and may cause abdominal pain, bloating, excessive gas, diarrhea, constipation, or both.
IBS is a chronic condition that can persist over a long period or recur frequently.
The pathogenesis of IBS involves a complex interplay of the following factors:
