Mutation dynamics and fitness effects followed in single cells.

Mutations have been investigated for more than a century but remain difficult to observe directly in single cells, which limits the characterization of their dynamics and fitness effects. By combining microfluidics, time-lapse imaging, and a fluorescent tag of the mismatch repair system in, we visualized the emergence of mutations in single cells, revealing Poissonian dynamics. Concomitantly, we tracked the growth and life span of single cells, accumulating ~20,000 mutations genome-wide over hundreds of gen...


Associations of discretionary screen time with mortality, cardiovascular disease and cancer are attenuated by strength, fitness and physical activity: findings from the UK Biobank study.

Discretionary screen time (time spent viewing a television or computer screen during leisure time) is an important contributor to total sedentary behaviour, which is associated with increased risk of mortality and cardiovascular disease (CVD). The aim of this study was to determine whether the associations of screen time with cardiovascular disease and all-cause mortality were modified by levels of cardiorespiratory fitness, grip strength or physical activity.

The effects of short term detraining and retraining on physical fitness in elite soccer players.

The aim of this study was to examine the effects of aerobic high-intensity training with reduced volume and training cessation on body composition and physical fitness after the end of season and the time required to recapture physical fitness with intensified retraining following two weeks of detraining in elite soccer players.


Longitudinal Evaluation of Aerobic Fitness and Academic Achievement Among Schoolchildren.

Research is emerging suggesting that fitness not only improves health, but enhances academic achievement in children. Many studies have found the strongest correlation with academic achievement to be aerobic fitness. The purpose of this study is to examine the influence of aerobic fitness and academic ranking on the association between improvements in students' aerobic fitness and their academic achievement.

Secular Trends in the Physical Fitness of United States Army Infantry Units and Infantry Soldiers, 1976-2015.

The purpose of this investigation was to examine changes over time in the physical fitness of the United States (US) Army infantry.

Associations between physical fitness and adherence to the Mediterranean diet with health-related quality of life in adolescents: results from the LabMed Physical Activity Study.

Physical fitness (PF) and adherence to the Mediterranean diet are important indicators of healthy lifestyles. The purpose of this study is to analyze the independent and combined associations between PF and adherence to Mediterranean diet with health-related quality of life (HRQoL) in adolescents.

The Impact of Behavioral and Psychological Factors on Physical Fitness in Medical and Nursing Students.

Physical activity improves general health and quality of life. A stressful academic environment can increase both physical and mental health disruptions in medical and nursing students, negatively impacting physical activity and fitness. We explored the relationship between the fitness profiles of 202 medical and graduate nursing students with self-reported levels of general and emotional health to elucidate the role of the psychosocial factors involved in choosing to exercise.

Dynamics in the Fitness-Income plane: Brazilian states vs World countries.

In this paper we introduce a novel algorithm, called Exogenous Fitness, to calculate the Fitness of subnational entities and we apply it to the states of Brazil. In the last decade, several indices were introduced to measure the competitiveness of countries by looking at the complexity of their export basket. Tacchella et al (2012) developed a non-monetary metric called Fitness. In this paper, after an overview about Brazil as a whole and the comparison with the other BRIC countries, we introduce a new meth...

The Association Between Self-Rated Fitness and Cardiorespiratory Fitness in Adults.

To assess criterion validity of a single item question on self-rated physical fitness against objectively measured cardiorespiratory fitness. From the Health2008 study 749 men and women between 30 and 60 years of age rated their fitness as excellent, very good, good, fair or poor. Cardiorespiratory fitness was estimated with the watt-max test. Agreement between self-rated and objectively measured physical fitness was assessed by Cohen's weighted kappa coefficient. Correlation was determined by Goodman & Kru...

Subtyping children with developmental coordination disorder based on physical fitness outcomes.

Children with Developmental Coordination Disorder (DCD) are known to have poor physical fitness. However, differentiating homogenous subgroups of DCD using fitness performance has not yet been established. Therefore the purpose of this study was to identify subtypes in children with and without DCD using measures of physical fitness.

Assessing Psychological Fitness in the Military - Development of an Effective and Economic Screening Instrument.

There are a high number of soldiers with deployment-related and non-deployment-related mental health problems in the German Armed Forces (Bundeswehr): This has led to an increase in mental disorders and a decrease in quality of life. To tackle these problems and to strengthen resources among the Bundeswehr personnel, this study aims at developing a screening instrument for assessing the psychological fitness of soldiers on the basis of questionnaire scales. In this approach, psychological fitness describes ...

Quantification and decomposition of environment-selection relationships.

In nature, selection varies across time in most environments, but we lack an understanding of how specific ecological changes drive this variation. Ecological factors can alter phenotypic selection coefficients through changes in trait distributions or individual mean fitness, even when the trait-absolute fitness relationship remains constant. We apply and extend a regression-based approach in a population of Soay sheep (Ovis aries) and suggest metrics of environment-selection relationships that can be comp...

Functional outcome in contemporary children with total cavopulmonary connection - Health-related physical fitness, exercise capacity and health-related quality of life.

Children and adolescents with an univentricular heart after total cavopulmonary connection (TCPC) have functional impairments. This study assesses health-related physical fitness (HRPF) and exercise capacity, as well as their relation to health-related quality of life (HRQoL) in patients with an univentricular heart after total-pulmonary connection (TCPC).

Life-History Multistability Caused by Size-Dependent Mortality.

Body size is a key determinant of mortality risk. In natural populations, a broad range of relationships are observed between body size and mortality, including positive and negative correlations. Previous evolutionary modeling has shown that negatively size-dependent mortality can result in life-history bistability, with early maturation at small size and late maturation at large size representing alternative fitness optima. Here we present a general analysis of conditions under which such life-history bis...

The accessibility of fitness centers for people with disabilities: A systematic review.

Fitness centers could be ideal places for people with disabilities to engage in the recommended levels of physical activity for healthy well-being. However, one of the primary barriers to participation at fitness centers is an inaccessible built environment.

Detrimental effects of rhizobial inoculum early in the life of partridge pea, Chamaecrista fasciculata.

Mutualistic relationships with microbes may aid plants in overcoming environmental stressors and increase the range of abiotic environments where plants can persist. Rhizobia, nitrogen-fixing bacteria associated with legumes, often confer fitness benefits to their host plants by increasing access to nitrogen in nitrogen-limited soils, but effects of rhizobia on host fitness under other stresses, such as drought, remain unclear.

Host Plant Infection by Soybean Mosaic Virus Reduces the Fitness of Its Vector, Aphis glycines (Hemiptera: Aphididae).

Coevolutionary interactions between pathogens and their insect vectors can dramatically impact the fitness of herbivorous insects and patterns of plant disease transmission. Soybean mosaic virus (SMV) is a common disease in soybean production worldwide. Infected seed is the primary source of inoculum in fields and the virus is secondarily spread among plants by the soybean aphid, Aphis glycines Matsumura (Hemiptera: Aphididae), in a nonpersistent manner. In this study, we compared the biological fitness of ...

Fitness Mediates Activity and Sedentary Patterns Associations with Adiposity in Youth.

We aimed to examine the cross-sectional associations of patterns of sedentary time (ST) and moderate-to-vigorous physical activity (MVPA) with total fat mass index (FMI) and abdominal fat mass index (FMIabd) in children, and additionally, to analyze if cardiorespiratory fitness (CRF) mediated these associations.

Adding smoking to the Fardal model of cost-effectiveness for the life-time treatment of periodontal diseases.

Little is known about the financial costs that smoking adds to the life-time treatment of periodontal disease.

Predictors of Cardiorespiratory Fitness Improvements With Cardiac Rehabilitation: Lower Baseline Fitness With the Most to Gain, Gains the Most.

The influence of winter and summer seasons on physical fitness in aged population.

Epidemiological studies have described the association between physical fitness and health. Few have reported the impact of seasonal variation on fitness determinants, in elderly. We investigated the effects of summer and winter environmental conditions on physical fitness, in both exercise and non-exercise elders. 371 non-institutionalized older adults (74.1% female; 78.4 ± 5.3 years) randomly recruited from a total sample of 1338 subjects from north of Portugal, were prospectively followed during 1...

Environmentally induced development costs underlie fitness tradeoffs.

Local adaptation can lead to genotype-by-environment interactions, which can create fitness tradeoffs in alternative environments, and govern the distribution of biodiversity across geographic landscapes. Exploring the ecological circumstances that promote the evolution of fitness tradeoffs requires identifying how natural selection operates and during which ontogenetic stages natural selection is strongest. When organisms disperse to areas outside their natural range, tradeoffs might emerge when organisms ...

The RESTORE Randomized Controlled Trial: Impact of a Multidisciplinary Rehabilitative Program on Cardiorespiratory Fitness in Esophagogastric cancer Survivorship.

The Rehabilitation Strategies in Esophagogastric cancer (RESTORE) randomized controlled trial evaluated the efficacy of a 12-week multidisciplinary program to increase the cardiorespiratory fitness and health-related quality of life (HRQOL) of esophagogastric cancer survivors.

Altered life history strategies protect malaria parasites against drugs.

Drug resistance has been reported against all antimalarial drugs, and while parasites can evolve classical resistance mechanisms (e.g., efflux pumps), it is also possible that changes in life history traits could help parasites evade the effects of treatment. The life history of malaria parasites is governed by an intrinsic resource allocation problem: specialized stages are required for transmission, but producing these stages comes at the cost of producing fewer of the forms required for within-host survi...

The Association Between Sustained Poor Quality of Life and Future Opioid Use in Inflammatory Bowel Disease.

Inflammatory bowel disease (IBD) is associated with poor quality of life and disability. The short inflammatory bowel disease questionnaire (SIBDQ) is validated to determine patients quality of life at single time points, or improvement over time. Few studies have evaluated if sustained poor quality of life is associated with future healthcare utilization patterns.
