Inter-individual variation in saliva antioxidant status in relation to periodontal disease
… antioxidant flow rate was significantly lower in individuals with severe PD (TAA 0.2 10 ± 0.02 M/ml/min) than those with healthy gingivae (TAA 0.270 ± 0.02 iiM/ml/min) (p

Inter-individual variation within social groups: how metabolic rate shapes the pace of life
… physiological, and life-history traits in individual bees and used a path analysis to demonstrate that variation in metabolic rate plays a fundamental proximate role in driving the covariance among these traits. We combined this with a factor analysis in a structural equation model …

Who Exercises and When? The Effects of Intra- and Inter-Individual Variation on the Likelihood and Duration of Exercise
The current study examined the ability of inter- and intra-individual characteristics to predict the likelihood and duration of exercise as well as mood. One hundred forty-nine undergraduates (mean age = 19.11; 53% women; 79.19% White) participated in a six-day study. Online surveys measured …

An integrative, community-collaborative approach to investigating health, diet, and the oral microbiome in ancestral and descendant coast Tsimshian communities
… from burials and household structures at winter villages along the coastline of Prince Rupert Harbour indicate that as warfare and the accumulation of personal wealth increased, the social complexity of the ancestral community increased and individual status differentiation emerged. The …

Models for Investigating the Biology of Sexual Differentiation
… few of these differences are fully understood. Inter-individual differences exist within the sexes as well. Sexual differentiation is the process of development of these differences. The study of sexual differentiation is itself a discipline, with different concepts and methods applied across …

Stopover behavior and refueling physiology in relation to migration distance in Wilson's Warblers (Wilsonia Pusilla)
I investigated how inter-individual variation in total migration distance within a species affects stopover behavior and refueling rate. Wilson’s Warbler is a leapfrog migrant passerine that winters in Central America and breeds throughout North America. Birds were captured in the spring and fall …

Human Versus Computer Algorithmic Measurements of Caloric Response: Implications for Test Analysis
Objectives: To quantify variation introduced to bithermal caloric test (BCT) analysis by data cleaning and determine how variation differs between examiners. Methods: Analysis of 435 consecutive BCTs performed by 6 examiners using identical protocols on adults with dizziness. Outcomes of total eye …

Pharmacokinetic and pharmacodynamic studies of mycophenolic acid in renal transplant recipients
… the IC50 of free MPA, substantially reducing inter-individual variation in this PD parameter by 5.3% and intra-individual variation by 25.47%.This study confirmed that patients taking MMF and SRL experience a higher exposure to MPA and lower exposure to MPAG and the population PK-PD model …

Dietary Manipulation of Metabolic Function in the Human Gut Microbiome
… treatment potential is limited by substantial inter-individual variation in responses to prebiotics. Determining the cause for this variation is necessary to develop treatment approaches that maximize patient responsiveness. Ultimately, tools to predict an individual’s response to a prebiotic …

Post-exercise oxygen consumption and heart rate recovery as possible measures of the homeostatic stress of an exercise bout Theresa Naomi Carol Mann.
Several methods have been used to quantify the internal training load of a bout of exercise. However, arecent novel approach to quantify the internal training load has been to investigate the dynamic returntowards resting homeostasis at the cessation of exercise. Objective and non-invasive methods …

Gut Microbiota of Migratory Passerines at Stopover
… sequencing. Despite showing large inter-individual variation, a core microbiota composed largely of Firmicutes and Proteobacteria was identified in all birds. Microbiota profiles were not related to the energetic condition of birds in either season, therefore microbiota communities …

On the proximate links between object play and tool use in the context of stone handling behavior in Balinese long-tailed macaques
… Balinese long-tailed macaques. First, I assessed inter-individual variation and intra-individual consistency in the expression of SH behavior, and whether the physical properties of the objects being manipulated (i.e., stone size) affected an individual’s expression of SH activity. Second, I …

Prediction of age from DNA

Biomarkers in sepsis and other severe infections
… as indicated by cell surface phenotype, a large inter-individual variation of immune activation and immunosuppression was detected in patients with sepsis, with a dominance of immunosuppression in patients with septic shock. Finally, different types of immature myeloid immunosuppressive cells, …

Genetic Predictors of Hyperglycemia Due to Hydrochlorothiazide Therapy
… to pharmacological treatment is variable among individuals. Some patients respond favorably to a drug while others develop adverse reactions. Early investigations showed evidence of variation in genes that code for drug receptors, drug transporters, and drug metabolizing enzymes; and …

Hide and seek : a multidisciplinary study on the ecological success of an estuarine dweller
… requires flexibility in dealing with these variations, which include changes in food availability and shelter opportunities. A thorough understanding of ecological networks in these systems, therefore, relies on comprehensive information on anti-predator adaptations and trophic relationships …

Acute exercise and postprandial triglyceride metabolism: mechanisms for the exercise effect and implications for endothelial function
… or by carbohydrate refeeding. Considerable inter-individual variation was evident in the LPL response to exercise, with changes in LPL actlvity inversely related to changes in postprandial lipemia. Taken together, these studies confirm that single bouts of exercise can reduce postprandial …

The role of crude saliva and purified salivary mucins in the inhibition of the Human Immunodeficiency Virus type 1
… the world's worst HIV-AIDS affected region. More interventions to manage this pandemic are urgently required. Transmission of the virus through an exchange of saliva is rarely known to occur. The role of saliva and its mucus in this inhibition requires clarification. This project sought to verify …

Dietary bioactives and cardiovascular health
… through the implementation of two human dietary intervention studies: the Cardio-Rubus (blackberry-polyphenols) and Cardio-Protein (ovalbumin-derived peptides) randomised controlled trials (RCTs). Our findings indicate that the consumption of ovalbumin-derived peptides for 6-weeks does not have …

Conserving Connectivity: Ecological Determinants of Gene Flow in Plants at the Landscape Scale
… the contributions of landscape structure, individual plant characteristics, and directed seed dispersal to gene flow of plants in fragmented landscapes. First, I used simulations to test if models of pollen flow could be improved by incorporating individual plant characteristics that affect …
