The effects of prolonged standing compared to prolonged sitting on postprandial lipemia
Prolonged periods of sedentary behavior are linked to cardiometabolic disease independent of many risk factors including exercise and activity levels. This study examined the effects of posture, rather than activity by comparing one full day of sitting (14.45 ± 0.286 hours) compared to one full day …

Identifying salivary biomarkers associated with prolonged sitting
The effect of prolonged sitting on salivary biomarker concentrations is relatively unexplored. The purpose of this work was to identify novel biomarkers, detectable in the saliva in response to prolonged and interrupted bouts of sitting. Participants completed three sessions. The first session …

Prolonged Lumbar Flexion Disturbs Paraspinal Reflex Behavior
The neuromuscular response to prolonged lumbar flexion has recently been extensively studied in felines but has not been examined in humans. Animal studies suggest that prolonged lumbar flexion disturbs neuromuscular control of paraspinal muscles. This disturbance was linked to creep deformation of …

The Evolution of Fitness After Prolonged Sperm Storage
A series of recent studies using Drosophila melanogaster suggest that while males may benefit from having access to many partners, female fitness is reduced by extended cohabitation and sexual interaction with males. Yet, even if repeated sexual interactions are harmful to females, limited male …

Predictors of prolonged opioid use following lumbar fusion
… of this study is to assess predictors of prolonged opioid use after lumbar fusion. We designed a retrospective cohort of patients who underwent lumbar fusion in 2009. We used claims data from Clinformatics Data Mart. The cohort consisted of 630 non-workers compensation (WC) adults, age …

Carbohydrate intake and metabolism during prolonged endurance exercise
… fine-tuning CHO intake recommendations during prolonged endurance events. A way to measure the bioavailability of ingested CHO is to measure exogenous CHO oxidation with the use of \(^{13}\)C or \(^{14}\)C tracers. This, however, has been studied only with CHO solutions, predominantly during …

Factors influencing ammonia metabolism during prolonged exercise in man
The studies that comprise this thesis were undertaken to obtain further information on ammonia/ammonium (NH3) metabolism during submaximal exercise and how it might be influenced by (1) exercise intensity and duration, (2) carbohydrate ingestion and (3) branched-chain amino acid (BCAA) feeding. A …

Causes and consequences of prolonged dormancy: Why stay belowground?
<p>Prolonged dormancy is a stage in which mature plants fail to resprout during the growing season and instead remain alive belowground. Though it is relatively common, the causes and consequences of this intriguing stage have remained elusive. In this dissertation, I investigate the causes and …

Mechanisms of fatigue during prolonged exercise in the heat
Increase in body temperature is a major factor limiting endurance performance in the heat and it is shown in this thesis that the effects of raised body temperature on performance, perception and neuroendocrine response to exercise are mediated by an interaction of body temperatures. Prolactin has …

Molecular implications of prolonged DDT selection in Drosophila melanogaster
… strain in order to characterize the impact of prolonged DDT selective pressure on genetic diversity for those strains. Comparing the transcriptomic response to DDT in 91-R and 91-C, I identified a multigenic adaptive response to DDT in 91-R along with multiple roles for gene regulatory cascades …

Resultant Suicide from Prolonged Grief for Caregivers of Cancer Victims
… based around the question “How can suicide from prolonged grief for family members/caregivers of cancer victims be identified earlier and treated successfully?” Problem/Purpose: The research focus was the impact of suicidal ideation, identifying areas of improvement to provide a substantial and …

Response of salivary IL-8 to prolonged and interrupted sitting
The effect of prolonged sitting on inflammation, as determined by cytokine profiles, is relatively unexplored. The purpose of this work was to determine the reliability of salivary IL-8 (CXCL8) and the response of IL-8 to prolonged and interrupted sitting. Participants completed two sessions in …

Chromatin-based memory of prolonged cold exposure in Arabidopsis thaliana
… plant Arabidopsis thaliana is repressed by the prolonged cold of winter, and repression is maintained in subsequent warm conditions. The molecular complexes involved in modulating FLC chromatin are vital for FLC regulation and are conserved among plants and animals, making FLC a paradigmatic …

Evaluation of Metabolic Energy Expenditure During Prolonged Steady-State Exercise
Energy consumed during prolonged steady state exercise was partitioned to radiant, convective and evaporative heat and the energy for climbing and walking. Healthy, non-obese subjects, ages 20 to 35 years, were classified as 5 active males, 5 trained males, 5 active females and 5 trained females. …

Selected physiological and perceptual responses of males during prolonged exercise
Six males of similar body composition and aerobic physical fitness were tested to determine their perceptual responses to exercise and the relation of these perceptions to core temperature (Tᵣₑ) under three conditions of thermoregulatory stress. The experimental protocol consisted of 120 min of …
