Transcutaneous electrical nerve stimulation and placebo analgesia: is the effect the same for young and older individuals?
(2018)Abstract: Purpose: Placebo analgesia refers to a perceived reduction in pain intensity following the administration of a simulated or otherwise medically ineffective treatment. Previous studies have shown that many factors ... -
Guidelines for assessment of gait and reference values for spatiotemporal gait parameters in older adults: The biomathics and canadian gait consortiums initiative
(2017)Abstract: Background: Gait disorders, a highly prevalent condition in older adults, are associated with several adverse health consequences. Gait analysis allows qualitative and quantitative assessments of gait that improves ... -
Aging across the tree of life: the importance of a comparative perspective for the use of animal models in aging
(2017)Abstract: Use of model organisms in aging research is problematic because our ability to extrapolate across the tree of life is not clear. On one hand, there are conserved pathways that regulate lifespan in organisms ... -
Validating metabolic syndrome through principal component analysis in a medically diverse, realistic cohort
(2012)Abstract: Background: The concept of metabolic syndrome has been subject to etiological and clinical controversies in recent years. Associations among the five risk factors (obesity, high blood pressure, high blood sugar, ... -
A novel statistical approach shows evidence for multi-system physiological dysregulation during aging
(2013)Abstract: Previous studies have identified many biomarkers that are associated with aging and related outcomes, but the relevance of these markers for underlying processes and their relationship to hypothesized systemic ... -
Cross-population validation of statistical distance as a measure of physiological dysregulation during aging
(2014)Abstract: Measuring physiological dysregulation during aging could be a key tool both to understand underlying aging mechanisms and to predict clinical outcomes in patients. However, most existing indices are either circular ... -
Inflamm‐aging does not simply reflect increases in pro‐inflammatory markers
(2014)Abstract: Many biodemographic studies use biomarkers of inflammation to understand or predict chronic disease and aging. Inflamm-aging, i.e. chronic low-grade inflammation during aging, is commonly characterized by ... -
A novel measure of physiological condition based on multivariate distance predicts maximal thermogenic capacity and inflammation in a migratory shorebird
(2014)Abstract: The body condition of free-ranging animals affects their ability to fulfil their vital needs, their response to stress, their decisions, and ultimately their fitness, with important evolutionary consequences. It ... -
Effects of categorization method, regression type, and variable distribution on the inflation of Type-I error rate when categorizing a confounding variable
(2015)Abstract: The loss of signal associated with categorizing a continuous variable is well known, and previous studies have demonstrated that this can lead to an inflation of Type-I error when the categorized variable is a ... -
Physiological regulatory networks: ecological roles and evolutionary constraints
(2012)Abstract: Ecological and evolutionary physiology has traditionally focused on aspects of physiology one at a time. Here, we discuss the implications of considering physiological regulatory networks (PRNs) as integrated ... -
Physiological and comparative evidence fails to confirm an adaptive role for aging in evolution
(2015)Abstract: The longstanding debate about whether aging may have evolved for some adaptive reason is generally considered to pit evolutionary theory against empirical observations consistent with aging as a programmed aspect ... -
Deep transcriptome annotation enables the discovery and functional characterization of cryptic small proteins
(2017)Abstract : Recent functional, proteomic and ribosome profiling studies in eukaryotes have concurrently demonstrated the translation of alternative open-reading frames (altORFs) in addition to annotated protein coding ... -
Rural-urban disparities in the management and health issues of chronic diseases in Quebec (Canada) in the early 2000s
(2010)Abstract: Introduction: The ‘Commission on the Future of Health Care in Canada’ recognized that people living in rural and remote areas of Canada are at a disadvantage in health status, access to care and health professionals, ... -
Stress, metabolism, and antioxidants in two wild passerine bird species
(2008)Abstract: Antioxidants protect against free-radical damage, and free radicals, in turn, are thought to underlie aging. Thus, measuring antioxidants mayaid fieldecologistsinunderstandingthephysiological mechanisms that ... -
Interspecific associations between circulating antioxidant levels and life-history variation in birds
(2008)Abstract: Antioxidants play an important role in protecting tissues against aging-associated oxidative damage and are thus prime candidates for relating physiological mechanisms to variation in life histories. We measured ... -
No consistent effects of prenatal or neonatal exposure to Spanish flu on late-life mortality in 24 developed countries
(2010)Abstract: We test the effects of early life exposure to disease on later health by looking for differences in late-life mortality in cohorts born around the 1918-1919 flu pandemic using data from the Human Mortality Database ... -
The Summary Index of Malaria Surveillance (SIMS): a stable index of malaria within India
(2010)Abstract: Background: Malaria in India has been difficult to measure. Mortality and morbidity are not comprehensively reported, impeding efforts to track changes in disease burden. However, a set of blood measures has been ... -
What does carotenoid-dependent coloration tell? Plasma carotenoid level signals immunocompetence and oxidative stress state in birds–A meta-analysis
(2012)Abstract: Mechanisms maintaining honesty of sexual signals are far from resolved, limiting our understanding of sexual selection and potential important parts of physiology. Carotenoid pigmented visual signals are among ... -
Ecological immunology in a fluctuating environment: an integrative analysis of tree swallow nestling immune defense
(2013)Abstract : Evolutionary ecologists have long been interested by the link between different immune defenses and fitness. Given the importance of a proper immune defense for survival, it is important to understand how its ... -
Detection of a novel, integrative aging process suggests complex physiological integration
(2015)Abstract: Many studies of aging examine biomarkers one at a time, but complex systems theory and network theory suggest that interpretations of individual markers may be context-dependent. Here, we attempted to detect ...
