Conformational fluidity of intrinsically disordered proteins in crowded environment: a molecular dynamics simulation study.

The class of intrinsically disordered proteins lacks stable three-dimensional structures. Their flexibility allows them to engage in a wide variety of interactions with other biomolecules thus making them biologically relevant and efficient. The intrinsic disorders of these proteins, which undergo binding-induced folding, allow alterations in their topologies while conserving their binding sites.

Similarities and differences regarding acute anorexia nervosa and semi-starvation: does behavioral thermoregulation play a central role?

Objective: To clarify the association between acute anorexia nervosa (AN) and semi-starvation (SS) by focusing on similarities and differences in physiology, mood, and behavior.

Method: A comparison of published literature between these two groups.

Results: Both groups show similar hormonal and metabolic changes in response to caloric restriction and extreme weight loss (~25%).

The Central Role of Hypothermia and Hyperactivity in Anorexia Nervosa: A Hypothesis.

Typically, the development of anorexia nervosa (AN) is attributed to psycho-social causes. Several researchers have recently challenged this view and suggested that (HyAc) are central to AN. The following hypothesis will attempt to clarify their role in AN.

Differing cytokine responses by ethnic groups to a bout of exercise-induced muscle damage: a preliminary report.

Background: Strenuous exercise has been shown to alter immune and inflammatory responses potentially predisposing athletes to infection and injury. Ethnic disparities have been demonstrated in athletic performance and in the way individuals respond to exercise as well as in the predisposition towards certain diseases however, the information relating to immune and inflammatory responses to exercise between ethnic groups is still limited. The aim of this study was to investigate whether serum cytokine levels respond differently to eccentrically-biased exercise in African and Caucasian males.

McArdle disease: another systemic low-inflammation disorder?

McArdle disease is caused by inherited deficit of human muscle glycogen phosphorylase with subsequent blockade in muscle glycogenolysis. Patients usually experience severe exercise intolerance and 'chronic' skeletal muscle damage. We determined circulating levels of 27 cytokines in a group of 31 adult McArdle patients (15 male 16 female; mean (+/-S.

Changes in serum cytokines after repeated bouts of downhill running.

The purpose of this study was to examine changes in serum cytokines after repeated bouts of aerobically biased eccentric exercise. Six untrained males ran down a -13.5% treadmill grade for 60 min on two occasions (RUN1 and RUN2) at a speed equal to 75% of their VO2 peak on a level grade; runs were spaced 14 d apart.

Perspectives from the front lines of tobacco control.

This research is designed to share valuable experiences and transferable principles from program staff of the Legacy/Community Voices initiative who have been involved in planning, implementing, evaluating, and sustaining tobacco control activities in underserved communities. Interviews were conducted with 13 front line staff from 9 sites: Alameda County, California; Detroit, Michigan; El Paso, Texas; Ingham County, Michigan; Miami, Florida; New Mexico; North Carolina; Northern Manhattan; and West Virginia. A model emerged from these interviews that places the life cycle of a program in a central position, with many of the identified themes (working with local champions, obtaining support from multiple partners, increasing organizational capacity) repeated throughout, albeit in different forms at different stages.

Tissue trauma: the underlying cause of overtraining syndrome?

An athlete who trains intensely, yet consistently underperforms, is considered to be suffering from overtraining syndrome (OTS). OTS is a complex state that involves a large variety of signs and symptoms. Symptoms include changes in mood or behaviour, decreases or increases in concentration of different blood molecules, and alterations in immune function.
