Expression of Nerve Growth Factor in Human Dental Pulp Tissues Following Orthodontic Force 正畸力作用下人牙髓组织中神经生长因子的表达
Objective To analyse the mechanics character of cross action forceps for optic nerve injury, and investigate a facile method to measure the clip force of the forceps. 目的分析视神经损伤反向夹持镊的力学性质,探索一种简易的测量反向镊夹持力的方法。
The fit nerve nervously is measure and the prerequisite to lift explosive force. 适宜的神经紧张是提高爆发力的手段和前提。
The suggested method is examined for pairs of regions with known attenuation laws of the intensity and ground motion. Result makes known: Nerve maneuver intensity is the strong and weak base of explosive force; 文中利用几个地区已知的地震动和烈度衰减资料对建议的方法作了比较验证。结果表明:神经活动的强度是爆发力强弱的基础;
Comparing to the passively stretched muscle, muscle activated by nerve contraction and stretched to failure attains a small increase in force at failure, no change in strain to failure, and large increase in energy absorbed prior to failure. 比较肌肉在被动拉伸和有神经刺激收缩的主动拉伸时发现,在损伤时拉伸力有小量增加,应变没有变化,但吸收能量的能力却有很大的变化。
[ Results] The electronic acupuncture may improve nerves muscle structure, metabolism and function, action potention, motor nerve conduction velocity and muscle contraction force, and advance damage nerves regeneration and nerves and muscle reinnervation. [结果]电针能够改善神经肌肉结构、代谢和功能,改善神经肌肉动作电位,运动神经传导速度以及肌肉收缩力,促进损伤神经再生和神经肌肉的神经再支配。
The traumatic optic nerve injury caused by blunt trauma to the forehead induced transmission of force to the confined portion of the optic nerve within the bony optic canal. 外伤性视神经损伤是在外力作用下引起的视神经损伤。
Methods The tibial nerve of rabbits was stimulated by impulse current with different pulse width and different current intensity giving by electromyography, meanwhile the Conductive Amplitude of Motion Potential ( CAMP) of the gastrocnemius and it's contractile force were recorded. 方法用肌电仪发出不同波宽、不同强度的脉冲电流,对家兔的胫神经进行刺激,记录其复合动作电位及收缩力。
This article predicts the nerve network control method to elevating force to control. 本文采用神经网络预测控制的方法对抬升力进行控制。
Pricking in skin insertion process of needle has been a problem in the process of diagnosis and treatment of disease, but the stimulus on nerve endings can be reduced with lower inserting force. 针刺皮肤引起的疼痛一直是疾病诊断与治疗过程中的一大难题,而降低针头刺入力能够减少针对神经末梢的刺激,从而实现微痛甚至无痛。
