Relationships between puroindoline A-prolamin interactions and wheat grain hardness.

Grain hardness is an important quality trait of cereal crops. In wheat, it is mainly determined by the Hardness locus that harbors genes encoding puroindoline A (PINA) and puroindoline B (PINB). Any deletion or mutation of these genes leading to the absence of PINA or to single amino acid changes in PINB leads to hard endosperms.

An international survey of perceptions of the 2014 FIFA World Cup: National levels of corruption as a context for perceptions of institutional corruption.

We conducted a survey about the 2014 FIFA World Cup that measured attitudes about FIFA, players, and officials in 18 languages with 4600 respondents from 29 countries. Sixty percent of respondents perceived FIFA officials as being dishonest, and people from countries with less institutional corruption and stronger rule of law perceived FIFA officials as being more corrupt and less competent running the tournament than people from countries with more corruption and weaker rule of law. In contrast, respondents evaluated players as skilled and honest and match officials as competent and honest.

Integrating sedentary behavior in the theoretical model linking childhood to adulthood activity and health? An updated framework.

About 30 years ago, Blair and collaborators proposed a theoretical model illustrating the relationships between childhood and adulthood physical activity and health. The evolution of our societies has led to a "sedentarisation" of the subsequent generations, and the literature underlines an independent effect of physical activity and sedentary behaviors on health. We propose here an updated version of the model first designed by Blair and colleagues, suggesting the integration of the impact of sedentary behaviors on children and adult health.

Impact of a 12-week high-intensity interval training without caloric restriction on body composition and lipid profile in sedentary healthy overweight/obese youth.

Although High-intensity interval training (HIIT) has shown its effectiveness in improving body composition, cardio-respiratory fitness and lipid profile in obese adults, evidences remain limited in overweight/obese youth. This study was conducted to investigate the effect of a 12-week HIIT program without caloric restriction on body composition and lipid profile among young overweight/obese men. Twenty healthy obese youth were randomly allocated into two groups; experimental group (HIIT) and control group.

Regional myocardial function abnormalities are associated with macro- and microcirculation dysfunction in the metabolic syndrome: the RESOLVE study.

Abnormalities in myocardial and vascular function have been reported in the metabolic syndrome (MetS), but whether these alterations are related remains poorly documented. Our aim was accordingly to investigate interrelationships between macro- and microcirculatory vasoreactivity and left ventricular (LV) myocardial function in MetS patients. Eighty-eight MetS individuals and 44 age- and gender-matched healthy controls were enrolled.

Proof-of-concept prototype development of the self-propelled capsule system for pipeline inspection.

This paper studies the prototype development for the self-propelled capsule system which is driven by autogenous vibrations and impacts under external resistance forces. This project aims for proof-of-concept of its locomotion in pipeline environment in order to mitigate the technical complexities and difficulties brought by current pressure-driven pipeline inspection technologies. Non-smooth multibody dynamics is applied to describe the motion of the capsule system, and two non-smooth nonlinearities, friction and impact, are considered in modelling.

Relationship between Force-Velocity Profiles and 1,500-m Ergometer Performance in Young Rowers.

Introduction: A need exists for sustainable and clinically effective weight management interventions, suitable for preventing well-linked chronic disease such as diabetes and cardiovascular disease and some less investigated secondary conditions such as bone alteration. The ADIposity and BOne metabolism: effects of eXercise-induced weight loss in obese adolescents (ADIBOX) protocol was designed to provide a better understanding of the interaction between adipokines and bone hormones in adolescents with obesity and how a 10-month physical activity programme may affect these interactions.

Methods And Analysis: The ADIBOX protocol combines 2 studies.

Differential effects of visual uncertainty and contextual guidance on perceptual decisions: Evidence from eye and mouse tracking in visual search.

Visual search can be seen as a decision-making process that aims to assess whether a target is present or absent from a scene. In this perspective, eye movements collect evidence related to target detection and verification to guide the decision. We investigated whether, in real-world scenes, target detection and verification are differentially recruited in the decision-making process in the presence of prior information (expectations about target location) and perceptual uncertainty (noise).
