概括
神经刺激 (TNS) 在各种脉冲宽度的猫中有效抑制了膀过度活跃. 没有单个脉冲宽度在过度活跃期间改善膀容量方面表现出更高的有效性.
科学领域:
- 神经科学是一个神经科学.
- 泌尿器科 泌尿器科 泌尿器科 泌尿器科
- 生物医学工程 生物医学工程
背景情况:
- 膀过度活跃是一种以非自愿的膀收缩为特征的疾病,导致尿急和尿频.
- 神经刺激 (TNS) 是一种神经调节技术,用于治疗下尿道症状,包括膀过活.
- 优化TNS参数,如脉冲宽度,对于最大限度地提高治疗疗效至关重要.
研究的目的:
- 在猫模型中评估TNS期间不同脉冲宽度 (60624微秒) 在抑制实验诱导的膀过活性的有效性.
- 为了确定特定的脉冲宽度是否与其他脉冲宽度相比,在反射上具有优越的抑制作用.
主要方法:
- 猫在左神经上进行了手术植入子电极.
- 使用乙酸 (AA) 输液诱导膀过活,正常盐水 (NS) 作为对照.
- 在2至4倍于值强度的TNS应用,脉冲宽度各不相同 (60,210,420,624微秒),并记录了囊仪表以评估膀容量和反射活性.
主要成果:
- 酸显著降低了膀容量,证实了诱导过度活动 (49.71%的NS对照).
- 无论脉冲宽度 (60,210,420,624微秒) 如何,TNS在AA输注期间显著增加了膀容量 (在NS对照中从70.65%到76.25%不等).
- 在测试的脉冲宽度中,在抑制膀过度活动方面没有发现有效性的显著差异,尽管值强度有所不同.
结论:
- 所有测试的TNS脉冲宽度都显示出对猫的膀过活性的显著抑制作用.
- 该研究发现,TNS脉冲宽度在60至624微秒之间抑制膀过度活动的有效性没有统计学上显著的差异.

Muscle Stimulation Frequency
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.
Wave summation
At low firing rates, motor neurons induce individual twitch contractions in muscle fibers. These twitches...

Disturbances in Heart Rhythm
Arrhythmia or dysrhythmia refers to an abnormal heart rhythm caused by a defect in the heart's conduction system. It can cause the heart to beat irregularly, too quickly, or too slowly, leading to symptoms like chest pain, shortness of breath, and fainting. Factors such as stress, caffeine, alcohol, nicotine, cocaine, certain drugs, congenital defects, diseases, and electrolyte abnormalities can trigger arrhythmias.
Arrhythmias are categorized by their speed, rhythm, and origin. A slow heart...

Regulation of Heart Rates
The regulation of heart rate is a complex process controlled by the autonomic nervous system (ANS), hormonal influences, and intrinsic cardiac mechanisms. The ANS has two main components: the sympathetic nervous system (SNS) and the parasympathetic nervous system (PNS).
The SNS increases heart rate through the release of norepinephrine and epinephrine, which act on beta-1 adrenergic receptors in the heart. This action increases the rate of depolarization in the sinoatrial (SA) node, the heart's...

ECG Interpretation of Arrhythmias II: Atrial, Junctional and Ventricular Arrhythmias
Arrhythmia is a condition characterized by an irregular heart rhythm, with ECG changes that differ based on its origin and nature. The types of arrhythmias discussed below include atrial, junctional, and ventricular arrhythmias.Atrial ArrhythmiasPremature Atrial Complexes (PACs): PACs are early atrial beats caused by stress, caffeine, alcohol, electrolyte imbalances, hypoxia, hyperthyroidism, or certain medications (e.g., bronchodilators and decongestants). The ECG shows early P waves with an...
