...hem for the endothelial antigen CD31. Vessels were quantified by digital morphometry (vessel density/field). Microvessel V3 expression was studied in vivo by confocal microscopy, and in vitro by flow cytometric analysis of human intestinal microvascular endothelial cells (HIMEC) activated by bFGF, VEGF and TNF-...Method to visualize gene activity may provide insight into normal development & genome function
...ecause the amount of fluorescence of each color is quantified separately. "When using the microscope to measure the fluorescence, the light is fanned out into a rainbow, and each color is read through a separate channel," explains Bier. "That way if the light is 90 percent blue and ten percent yellow, it mi...Study marks increased trends in infectious disease occurrences in our oceans
...ions and other potential biases. Ward and Lafferty quantified the reports of disease, and normalized the data by taking an annual proportion of disease reports and eliminating a variety of biases, such as multiple reporting of the same disease outbreak. The approach worked well for a test case, raccoon rabies. ...K-State uses geographic tools to track plant pathogens
...plications of insect dispersal and movement can be quantified and described in more detail using geographic information system techniques, Reese noted. "Our entomology graduate students routinely take GIS coursework or seek GIS certification. Pairing the two disciplines is a wide-open new field," he said. ...Antibiotics in the environment

There is an increasing concern that sub-therapeutic feeding of antibiotics in animal agriculture is increasing microbial resistanc...Double mastectomies significantly lower risk of breast cancer in women who are genetically at risk
...y at Penn's School of Medicine. "Now that we have quantified the benefit of a double mastectomy for reducing the chances of breast cancer, women in this high-risk group can make a better-informed decision about having breast surgery in addition to other forms of prevention, such as regular screening and/or oth...Secondary complications and restoration of function in SCI
...prostheses for people with SCI (pg 15) This study quantified and compared lower-limb passive joint moments in able-bodied volunteers and volunteers with SCI. Passive joint moments help control movement. Measuring and modeling the changes in passive properties following SCI will facilitate the development of be...Link between alcohol consumption and muscle damage in females
...e). The levels of c-myc, p53, and Bcl-2 mRNAs were quantified by RT-PCR with an endogenous internal standard, GAPDH. RT was performed on 1 g of total RNA for 90 min. Multiplexed PCR was carried out in a 20-l reaction mixture. PCR amplification was performed for 28 (c-myc), 30 (p53), or 34 (Bcl-2) cycles. After ...Natural selection in a nutshell

...t least eight hours. Glucose level was immediately quantified by an enzymatic colorimetric assay using a modified glucose oxidase-peroxidase method and an analyzer. Several 0.5-ml aliquots of serum were processed immediately and stored at 80C and subsequently used for the assessment of hormones and cytokines. ...Crows alter their thieving behavior when dealing with kin or other birds
