Studies in young women show that rowing exercise is osteogenic at the spine. However, little is known regarding rowing exercise and spine bone mineral density in older women. The aim of this study was to examine differences in spine bone mineral density (BMD) and back strength between premenopausal and postmenopausal...
Better Bones and Balance (BBB) is a community-based exercise program to improve bone health and reduce fall risk among older adults. Prior research has shown that when the program is delivered by researchers under controlled conditions, participants improved strength and balance, and maintained bone mineral density (BMD) at the hip....
Mycobacterium avium subsp. hominissuis (MAH) is a pervasive environmental bacterium that can cause opportunistic infections in humans. Among the most robust and hardy members of the Mycobacterium genus, M. avium can persist and thrive in a range of challenging environments, including many which place it in direct contact with humans....
Pesticides can often be toxic and for this reason their methods and quantities of application are extremely regulated. Pesticide applicators are at risk of permanently damaging their health from exposure to pesticides. In order to ensure that these employees have the proper information to protect themselves, they are required to...
A sucrose density-gradient ultracentrifugation technique for
obtaining microsomes has been developed. This technique has
advantages over the classic differential centrifugation technique, in
that it is faster, is better suited to work with small quantities of
tissue, and offers the opportunity to work with a defined microsomal
sub-cellular fraction, rather than...
The induction of drug-metabolizing enzymes is a
complex biochemical process manifested not only by
increases in various cytochrome P-450 isozymes and
related activities, but also by alterations in
endoplasmic reticulum membranes. Little work has been
done to examine how cytochrome P-450 inducing agents
influence other cellular processes, such as
phospholipid...
Snowpack base temperatures vary during accumulation and diurnally. Their measurement
provides insight into physical, biological and chemical processes occurring at the snow/soil interface.
Recent advances in Raman-spectra instruments, which use the scattered light in a standard
telecommunications fiber-optic cable to infer absolute temperature along the entire length of the fiber,...
Hydrologic processes control much of the export of organic matter and nutrients from
the land surface. It is the variability of these hydrologic processes that produces variable
patterns of nutrient transport in both space and time. In this paper, we explore how
hydrologic ‘‘connectivity’’ potentially affects nutrient transport. Hydrologic connectivity...
