Background: Umbilical cord infection developing subsequent to bacterial colonization is one of the outstanding reasons of newborn mortality and morbidity in underdeveloped and developing countries
中国科学院西北高原生物研究所药物化学学科组“快速检测、分离纯化和鉴定川西獐牙菜中四种活性化合物” 一文在Separation Science and Technology上发表
中国科学院西北高原生物研究所 药物化学
2015/3/25
该研究首先利用HPLC-MS技术检测出川西獐牙菜中龙胆苦苷、芒果苷、獐牙菜苷和异荭草苷四种目标化合物主要存在于正丁醇萃取部位中，然后利用HSCCC和Sephadex LH-20技术成功分离得到了四种高纯度目标化合物。所用方法简单、高效、不存在样品死吸附问题。
Blind Separation of Spatio-Temporal Synfire Sources and Visualization of Neural Cliques

Blind Separation of Spatio-temporal Data Sources
Blind Separation Spatio-temporal Data Sources visual scene
2010/1/7
ICA and similar techniques have been previously applied to either one-dimensional signals or still images. We consider the problem of blind separation of dynamic sources,i.e. functions of both time an...

Sparse ICA for Blind Separation of Transmitted and Reflected Images
transparent layers reflection polarization sparseness ICA blind source separation (BSS) wavelet packets clustering
2010/1/7
We address the problem of recovering a scene recorded through a semireflecting medium (i.e. planar lens), with a virtual reflected image being superimposed on the image of the scene transmitted throug...

Gas phase separation during decompression in man:ultrasound monitoring
decompression human Doppler
2009/7/20
During two dive series, one to 132 fsw and one to 210 fsw, Doppler ultrasonic bubble detectors were used to monitor venous gas bubbles in divers during decompression and for 30 min thereafter. Various...
Separation of basic parameters of decompression using fingerling salmon
argon decompression nitrogen neon
2009/7/17
The experimental limitations inherent in use of air-breathing vertebrates for studies of decompression are chiefly due to the difficulty in estimating supersaturation levels associated with both sympt...
Method for separation of cells and suspending medium at high pressure
human high pressure Method erythrocytes
2009/7/16
We describe a pressure chamber designed for measuring fluxes and equilibrium distributions of substances between cells in suspension and the extracellular medium at pressures up to 400 ATA. The pressu...
Hemodynamic Changes After Aortopulmonary Separation
Aortopulmonary septum blood pressure rat
2009/6/24
The neural crest origin of the aortopulmonary septum has led us to investigate the septum. We designed the present study to assess the hemodynamic changes following aortopulmonary separation in the ra...
Quantification of bovine sperm separation by a swim-up method. Relationship to sperm motility, integrity of acrosomes, sperm migration in polyacrylamide gel and fertility
Quantification bovine sperm separation swim-up method
2009/2/23
The number of bovine spermatozoa separated in a swim-up procedure was quantified using an electronic cell counter. In an initial test of the swim-up procedure, non-frozen sperm samples with differen...
Effects of substrate and separation method on acrosin amidase measurements
Enzyme activity DL-BAPNA L-BAPNA swim-up
2009/2/16
The purpose of this study was to increase the accuracy and reproducibility of the acrosin amidase assay and to assess the effects of different methods of sperm isolation on total sperm acrosin act...
Subfertility in stallions is common, and methodologies are needed to increase the fertility in these animals. In other species, removal of the dead sperm from semen increases the quality and ferti...
Effects of caudal elevation on testicular function in rats. Separation of effects on spermatogenesis and steroidogenesis
Hind-limb unloading testicular function testosterone spermatogenesis microgravity rats
2009/2/10
A variety of biologic processes are perturbed when exposed to microgravity (space flight) for more than 7 days, including testicular function. Suspension of rats in a special harness (caudal elevati...
