ABSTRACT Objective Currently, there are several surgical approaches to manage fetal open spina bifida (OSB), namely postnatal surgical repair, open fetal surgery and its minimally invasive alternative, fetoscopic repair. Our objective was to determine the optimal surgical approach for OSB, weighing the benefits and risks to the fetus and the pregnant ...

目的为了解男性的生殖健康状况及精液质量的趋势,对我院近九年检查的精液质量状况进行分析。方法按《WHO人类精液及精子-子宫黏液相互作用试验检验手册》标准,对本院1999年至2007年间共33871例精液,采用北京伟力彩色精子质量检测仪进行检测,并对每一年度精液常规与运动参数等项进行比较。结果1999年至2007年每年的精液质量比较中,年龄、精液量、液化时间、pH值之间无明显差别(P>0.05);而其他参数,如活动率、A级比例、B级比例及相关动态参数(包括运动的前向性(STR)、直线性(LIN)及摆动性 ...

Laser‐guided thin‐film self‐rolling for asymmetric small‐scale swimmers
Graphical abstract AbstractSmall‐scale robots are promising miniaturized devices in biomedicine. Thin‐film self‐assembly is a commonly used strategy to fabricate tubular small‐scale robots. However, the existing methods have limitations like complex manufacturing processes and limited control of self‐assembly behavior.

ABSTRACT Objectives Placental insufficiency contributes to many obstetric pathologies, but there is no bedside clinical tool to evaluate placental perfusion. We have developed a method to acquire multiple three‐dimensional (3D) power Doppler (PD) ultrasound (US) volumes of placental vasculature, with infrared camera tracking of the precise spatial ...

Abstract Background Cervical articular process joint (CAPJ) therapy is advocated for horses with neck disorders. Several ultrasound‐guided CAPJ techniques have been described in cadaver studies with 72%–89% intra‐articular injection accuracy; however, the CAPJ injection accuracy in clinical equine practice has not been extensively reported.

Abstract Introduction Drinking expectancies, the perceived consequences of alcohol consumption, are noted to predict drinking behaviours. However, there is comparatively little research of drinking expectancies in non‐Western populations. This study aimed to develop and validate a Chinese Drinking Expectancy Questionnaire (CDEQ‐Adult) for Chinese young

味精生产过程中经等电分离提取谷氨酸后排放的废母液称之为味精母液。目前,味精母液生物资源化利用主要研究培养酵母菌生产SCP方面,残留的色素资源化利用尚未见报道。本文针对利用味精母液培养酵母菌过程中存在的菌种环境适应能力低、菌体得率低、培养周期长以及残留色素的问题,通过对味精母液水质分析,筛选及驯化了一株优良酵母菌—苹果酒酵母菌,进行了培养条件和影响因素的实验和分析,确定了味精母液培养酵母菌的工艺及操作参数,分析了所培养的酵母菌的蛋白质含量并进行了评价 ...
