- 老年学是一门学科.
背景情况:
- 垂体唤起肌源潜能 (VEMPs) 对于评估垂体和耳神经功能至关重要.
- 与年龄相关的变化可以影响电生理反应,需要特定年龄的规范性数据.
研究的目的:
- 为了研究衰老对各种刺激频率的masseter VEMP (mVEMP) 响应参数的影响.
- 确定不同年龄组mVEMP测试的最佳刺激频率.
主要方法:
- 在三个年龄组 (18-35,36-55,55岁以上) 的60名参与者中记录了mVEMP反应.
- 使用频率为250,500,750,1000,1500和2000赫兹的音频爆发刺激.
- 分析包括P1/N1延迟,峰值到峰值振幅,间声振幅比率 (IAAR) 和间频振幅比率 (IFAR).
主要成果:

01:19The Effect of Aging on Tissues
3.1K
Several body functions deteriorate with age. The external signs of aging are easily identifiable. For example, the skin becomes dry, less elastic, and thins out, forming wrinkles. The skin of the face begins to appear looser due to a decrease in the levels of elastic and collagen fibers in the connective tissue. Additionally, melanin production in the hair follicle decreases with age, resulting in gray hair. Moreover, the senses of sight and hearing decline, so glasses and hearing aids may...

Age-related pharmacokinetic changes are extensively documented, but understanding age-related pharmacodynamic alterations is relatively limited. This knowledge gap can be partly attributed to the complexity of developing appropriate measures of drug responses compared to bioanalytical methods for determining drug concentrations.Most information regarding age-related differences in human pharmacodynamics originates from cross-sectional studies. However, these studies assume that observed mean...

01:29Bone Disorders
5.0K
Aging and its effect on bone remodeling is the most common cause of bone disorders. In young and healthy people, bone deposition and resorption happen at an equal rate to maintain optimal bone health.
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

01:22Muscle Stimulation Frequency
4.2K
The contraction strength of muscles is regulated by motor neurons, which modulate the frequency of action potentials dispatched to the motor units based on the body's requirements. This process of varying the muscle stimulation frequency allows muscles to contract with a force that is precisely tailored to the needs of the moment, whether lifting a feather or a heavy box.

At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...
