科学领域:
- ортодонтика和牙科发展
- 生理学 生理学 生理学
- 生物医学工程 生物医学工程
背景情况:
- 部生长是一个复杂的过程,受遗传和功能因素的影响.
- 自主神经系统 (ANS) 在调节包括肌肉活动在内的生理功能方面发挥着作用.
- 了解夜间ANS活动,肌功能和骨发育之间的相互作用,对于正牙诊断和治疗至关重要.
研究的目的:
- 调查夜间自主神经系统 (ANS) 活动与肌功能之间的相关性.
- 确定这些夜间活动和下大腿骨高度在患有骨II类缺陷的儿童之间的关系.
主要方法:
- 涉及患有骨II类缺陷的儿童的观察性研究.
- 在四个晚上收集了形光束计算机断层扫描 (CBCT) 图像,咬伤力测量以及夜间心率变化 (HRV) 和肌活动 (Duty Factor, DF) 数据.
- 分析了ANS活动的夜间超日循环,使用HRV测量的多项式拟合 (LF/HF比),并使用非线性回归使用与年龄和骨架高度相关的DF/HRV斜率.
主要成果:
- 发现大肌活动 (DF) 和ANS活动 (LF/HF比率) 之间的显著相关性,无论是masseter肌还是temporalis肌.
- 回归分析表明,大约42%的下大腿高度变异可以归因于年龄和按摩肌DF/HRV的综合影响.
- 较高的R平方值 (masseter的0.66,temporalis的0.56) 表明在睡眠期间肌肉活动和ANS调度之间存在很强的关系.
结论:
- 夜间部肌肉活动,受到交感管调的影响,似乎是决定幼儿下大腿高度的重要因素.

Assessment of Airway, Skin Color, and Use of Accessory Muscles
1.6K
A thorough assessment of respiratory health is paramount in clinical settings to identify and manage respiratory distress and ensure adequate oxygenation. This article elaborates on the critical aspects of respiratory evaluation, including airway assessment, skin color examination, and the observation of accessory muscle use, which are integral to effectively diagnosing and managing patients with respiratory conditions.

Changes in the Appendicular Skeleton with Age
3.4K
The upper and lower limb initially develops as a small bulge called a limb bud, which appears on the lateral side of the early embryo. The upper limb bud appears near the end of the fourth week of development, with the lower limb bud appearing shortly after.
Initially, the limb buds consist of a core of mesenchyme covered by a layer of ectoderm. The ectoderm at the end of the limb bud thickens to form a narrow crest called the apical ectodermal ridge. This ridge stimulates the underlying...

Restless Leg Syndrome and Night Terrors
487
Restless Leg Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder characterized by an uncontrollable urge to move the legs due to uncomfortable sensations. These sensations typically occur during periods of rest or inactivity, particularly when lying down or sitting, and can severely disrupt sleep.
The exact cause of RLS is not fully understood, but it is believed to involve dopamine, a neurotransmitter that helps regulate muscle movement. Imbalances in dopamine levels...

REM Sleep Behavior Disorder
1.4K
REM Sleep Behavior Disorder (RBD) is a sleep disorder characterized by the absence of muscle paralysis that normally occurs during the REM phase of sleep. This absence allows individuals to physically act out their dreams, which are often vivid and disturbing. Common behaviors exhibited during episodes include kicking, punching, and yelling. These actions can be dangerous, potentially leading to injuries for the person with RBD or their bed partner.

Sleep Apnea
481
Sleep apnea is a condition where breathing stops intermittently during sleep, often leading to significant health issues. Each episode can last from 10 to 20 seconds or more and is frequently accompanied by a brief arousal from sleep. This disturbance, largely unnoticed by the individual, can lead to severe daytime fatigue. Commonly, individuals seek help after being informed by their partners about loud snoring and noticeable breathing pauses during sleep.

Sleep-Wake Cycles
2.7K
Sleep is an essential physiological process vital to maintaining overall well-being. The reticular activating system (RAS), a network of neurons in the brainstem, regulates wakefulness and sleep. While it may seem passive, sleep consists of distinct cycles, each with its unique characteristics and functions. Two key sleep phases are non-rapid eye movement (NREM) and rapid eye movement (REM).
