The halogen bond is a non-covalent, stabilizing interaction analogous to a hydrogen bond in which an anisotropically polarized halogen atom interacts
electrostatically with a Lewis base. Until very recently, the ability of halogens to form these stabilizing interactions in biological macromolecules was all but unknown, but
examples of halogen bonding...
The purpose of this work was to develop a dynamic partial order model of II electrolyte solutions which avoids inconsistencies present in the Debye-1-Iuckel and 1n related theories. It is shown that our results are consistent with activity coefficient data in aqueous electrolyte solutions. The main features of our work...
Relationships between myosin heavy chain (MHC) isoform content and
eccentric-induced damage were investigated in chemically skinned muscle fiber
segments. Fibers were subjected to an eccentric contraction standardized for strain
magnitude (0.25 fiber length) and velocity (0.50 maximal shortening velocity).
Fiber MHC isoform content was identified by SDS-PAGE. Pre- to post-eccentric...
Recognizing the importance of native black cottonwood-dominated riparian
forests is especially important to preserve, protect, and manage for biodiversity in
the Willamette River Valley. Species composition, structure, and biomass along a
successional gradient from stand initiation to late succession of black cottonwood
(Populus balsamfera L. subsp. trichocarpa (T. & G.)...
The purpose of this study was to examine the effect of extreme exercise on vitamin B-6
metabolism and urea nitrogen. Nine men and five women completed two 5-day trials; Trial 1
(T1) included a 50-km ultramarathon on day 4 and during Trial 2 (T2) subjects were "inactive"
on day 4....
We investigated the effect of pyridoxine
supplementation on the utilization of protein in a low-protein,
plant-based diet in four subjects (2 men and
2 women), aged 21 to 38 years. Following two days of a
negligible protein diet, this 34 day study was divided into
three dietary periods: the subjects...
This investigation was conducted to determine the
effect of estrogen replacement therapy (ERT) on vitamin B-6
status of postmenopausal women. Nineteen postmenopausal
women served as subjects. Nine (54.7 + 4.7 years) were
taking ERT (experimental group); ten (56.8 + 2.3 years)
were not (control group). For three consecutive days,
subjects...
This investigation was designed to add to present understanding
of vitamin B-6 (B6) metabolism during exercise. Ten women, 5
aerobically trained and 5 untrained, were fed 4 controlled diets: a
moderate carbohydrate (49%) (MCHO) for 2 weeks, a high carbohydrate
(63%) (HCHO) for one week, MCH0+B6 for 2 weeks, and...
