Background: The effect of a weight-loss intervention on the masses of lean tissues and organs in humans is not well known.Objective: We studied the effects of a diet and exercise weight-loss intervent...
研制用于鼻咽癌放射治疗定位的CT/MRI图像配准辅助装置,并且通过组织勾画差异分析使用该装置后所得配准融合图像在临床中的应用意义。方法 在普通的磁共振头颈线圈中设计特定形状的头枕,保持患者在扫描时与CT定位扫描时相同的体位。采用配对t检验分析CT图像与融合图像中腮腺、下颌骨的勾画差异。结果 患者的头颈部CT、MRI图像的配准精度较未使用该装置的图像具有明显的提高,使用该配准图像得到的融合图像、组织...
提出了一种利用声光调谐方法进行滤波的扫频光源来提高它的输出稳定性。阐述了实现光源稳定输出的原理和方法,研究和分析了光源的相关参数。该系统采用声光调谐的方法代替机械滤波的方式。在一个环形腔内,使用半导体光放大器(SOA)作为增益介质,声光可调谐滤波器(AOTF)作为波长选择元件,利用声光调谐的原理对腔内的光进行选频滤波。在280 mA的注入电流下,得到了1 294~1 368 nm的扫频光源,其中心...
研究肿瘤相关黏蛋白MUC-1在上皮性卵巢癌中的表达,并探讨MUC-1在上皮性卵巢癌发生、发展中的作用。方法 采用免疫组化PV法测定32例上皮性卵巢癌组织、20例良性卵巢上皮肿瘤组织以及10例同期手术取正常卵巢组织中肿瘤相关黏蛋白MUC-1的表达情况。结果 MUC-1在上皮性卵巢癌中的表达与其在良性卵巢上皮肿瘤、正常卵巢组织中的表达间的差异均有统计学意义(P<0.05);MUC-1表达在后二者间的差...
The predominant view in economics is that individuals are unaware of the health effects of air pollution and therefore do not take them into account in making decisions (see Lester Lave). Given th...
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 ...
Increasing caloric intake is a promising treatment for exercise-associated amenorrhea, but strategies have not been fully explored. The purpose of this case report was to compare and contrast the res...
针对现有的上肢康复机器人的不足,设计一款新型的智能交互式上肢康复机器人帮助脑卒中偏瘫患者完成上肢康复训练。 方法:设计一种新型3个自由度的上肢康复机器人机械结构,利用套筒和弧齿锥齿轮组成的传动系统进行动力传输,所有电气系统元件统一安装于机器人底部机箱内减少噪音。设计电气控制系统,完成系统实验对样机进行验证,并用Unity3D引擎设计一款专用于本机器人的虚拟现实游戏使患者的训练更具有趣味性。 结果:...
由脑磁时序信号重建脑内时序神经信号时,除了要保证重建信号位置和强度的准确性,还要避免重建源信号在时域上瞬变.针对这一问题,提出了一种基于时域平滑约束的脑磁时序信号逆问题求解方法.该方法不同于传统最小范数估计算法(Minimum Norm Estimate,MNE),通过引入时域平滑正则算子构造双参数混合正则化,根据广义交叉验证(Generalized Cross-Validation,GCV)原则...
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...
