该系统具有以下特点:安全: 使具有潜在生物危害的样本始终处于封闭状态,从而保障了实验室工作人员的安全。质量:系统化、标准化、可溯源以及独特而先进的技术,保证了检验结果的准确。
ST段是心电图的重要组成部分,其起始于心电图QRS波群的结束点并结束于T波的开始点。ST段的压低、分上斜形和下垂形压低、水平压低和以及鱼钩样改变都可以反映各种心脏疾病,所以,精确提取心电图ST段具有重要意义。因此。本文提出了基于小波包变换的心电图ST段精确提取算法。方法:首先对心电图信号进行去噪处理,滤去工频干扰信号以及基线漂移信号;然后,提取单周期的心电图信号;最后,引入小波包变换算法提取QRS...
Literature Survey: - Acetylcholinesterase [AChE] is an enzyme that terminates Acetylcholine [ACh] mediated neurotransmission. Its wide neuronal and non-neuronal cellular distribution has made it the f...
Complex-dynamical fractal is a hierarchy of permanently, chaotically changing versions of system structure, obtained as the unreduced, causally probabilistic general solution of arbitrary interaction ...
Background: Community participation plays an important role in control of Mosquito borne diseases. This study tries to assess impact of educational intervention on various aspects of mosquito borne di...
This Master of Science thesis, eye movements brain potentials and family history of alcoholism, has been completed at the Neural Systems Laboratory of Dr. Sean O’Connor. I am greatly indebted for the ...
Magnetic resonance (MR) spectroscopy is a neuroimaging technique. It is widely used to quantify the concentration of important metabolites in a brain tissue. Imbalance in concentration of brain metabo...
Advancements in human genomics have simultaneously enhanced our basic understanding of the human body and ability to combat debilitating diseases. Historically, research has shown that there have been...
The time course and biological mechanisms by which breast cancer (BC) and/or alterations in estrogen status lead to cognitive and brain changes remain unclear. The studies presented here use neuroimag...
The etiology of many neurodegenerative diseases is unknown, but a number of studies indicate that a combination of both genetic and environmental factors contribute to the progression of disease. Expo...
Anxiety disorders are estimated to impact 1 in 4 individuals within their lifetime. For some individuals, repeated episodes of the stress response leads to pathological anxiety and depression. The str...
Our laboratory has previously identified the clock gene D-box Binding Protein (DBP) as a candidate gene for bipolar disorder and alcoholism using a Convergent Functional Genomics (CFG) approach. In su...
Impulsivity is associated with addiction in many human studies. Delay discounting (DD) is often used to measure impulsive choice in humans and animals. In DD testing, a small immediate reward is pitte...
探讨肌电生物反馈治疗对脑卒中患者步行能力的影响。 方法:62例可以独立步行5m以上,Brunnstrom分期下肢为4—5期的慢性脑卒中偏瘫患者,随机分为A、B两组,A组(观察组)在B组(对照组)常规物理疗法(PT)、作业疗法(OT)训练治疗同时增加肌电生物反馈治疗,治疗4周前后采用三维步态分析系统评测两组的步态空间域参数和步态时间域参数。 结果:A、B两组治疗后在步态空间域参数中平均步幅宽较治疗前...
Background RNA-binding proteins (RBPs) play important roles in cellular homeostasis by controlling gene expression at the post-transcriptional level. Results We explore the expression of more than 800...
