Mechanisms Of Hbo-Induced Neuroprotection In A Neonatal Hypoxia-Ischemia Model, John Winter Calvert

Loma Linda University Electronic Theses, Dissertations & Projects

With an incidence approaching 1/4000 live births and as high as 60% in low birth weight infants, cerebral hypoxia-ischemia during the perinatal period is the single most important cause of acute mortality and chronic disability in newborns. Herein, we tested the hypothesis that following a hypoxic-ischemic insult hyperbaric oxygen (HBO) treatment can restore high energy metabolite levels in the affected regions of the brain and through this increase in energy levels ameliorate the spread of cell death following the insult. We also investigated if an additional mechanism by which HBO affords its neuroprotection is by altering the expression of the …

Isokinetic Knee Strength In Females With Fibromyalgia, Flora F. Shafiee

Loma Linda University Electronic Theses, Dissertations & Projects

Objectives: To compare knee flexors and extensors muscle strength, total work, and power between females with fibromyalgia (FM) and matched healthy controls.

Methods: This is the first study to measure knee muscle power and total work in females with FM. Thirty-one females with FM and thirty-one healthy females completed isokinetic testing of knee flexors and extensors of their dominant leg using a Cybex Norm Isokinetic Dynamometer. Two knee muscle groups (flexors and extensors) at two angular velocities (607sec and 1807sec) were tested for both groups. Both muscle groups were assessed continuously using five reciprocal concentric-concentric cycles, followed by five eccentric-eccentric …

Effect Of Almond-Raisin Versus Commercial Sports Beverage On Antioxidant Status Of Runners, Anh Thu V. Tran

Loma Linda University Electronic Theses, Dissertations & Projects

Background: Whole foods are readily available antioxidant source and provide beneficial macromolecules and phytochemicals, which may contribute to optimal health. However, the approach to examining whole foods rich in antioxidants to play either an equivalent or better role in defending exercise-induced oxidant stress have not yet been taken. Objective: The objective of this study was to compare the effects of 2 isocaloric preexercise beverages: an almond-raisin beverage and a commercial sports beverage in male endurance runners on selected antioxidant status markers.

Design: In a randomized crossover study, 10 male runners (ages 28+1.2 years) ran to exhaustion on a treadmill at …
