Testosterone is a male sex hormone and low circulating testosterone levels are associated with various health disorders in men. Obesity results in reduced circulating testosterone levels in men. Previously, we demonstrated that lifestyle modifications (combination of aerobic exercise and dietary modification) increase circulating testosterone levels in overweight/obese men. However, the effect of regular aerobic exercise on serum testosterone levels remains unclear. The purpose of this study was to investigate the effect of a 12-week aerobic exercise intervention on circulating testosterone levels in normal-weight and overweight/obese men...

BACKGROUND: Physical activity is associated with a lower risk of disease recurrence among colon cancer survivors. Excess visceral adipose tissue is associated with a higher risk of disease recurrence among colon cancer survivors. The pathways through which physical activity may alter disease outcomes are unknown, but may be mediated by changes in visceral adipose tissue. METHODS: Thirty-nine stage I-III colon cancer survivors were randomised to one of three groups: usual-care control, 150 min wk(-1) of aerobic exercise (low dose) and 300 min wk(-1) of aerobic exercise (high dose) for 6 months...

The dependence on hydrostatic pressure of the electronic and optical properties of zinc-blende AlSb semiconducting material in the pressure range of 0-20kbar has been reported using a pseudopotential approach. At zero pressure, our findings showed that the electron and heavy hole effective masses are 0.11 and 0.38m0, respectively. Moreover, our results yielded values of 3.3289 and 11.08 for refractive index and high frequency dielectric constant, respectively. These results are found to be in good accord with experiment...

BACKGROUND: The correct estimation of the post mortem interval (PMI) can be crucial on the success of a forensic investigation. Diverse methods have been used to estimate PMI, considering physical changes that occur after death, such as mortis algor, livor mortis, among others. Degradation after death of dental pulp is a complex process that has not yet been studied thoroughly. It has been described that pulp RNA degradation could be an indicator of PMI, however this study is limited to 6 days...

Accumulated evidence indicates that nanoparticle behavior in complex biological environments strongly depends on the nanoparticles' surface chemistry. A common way to modify nanoparticles is to deposit oppositely charged molecules on the surfaces in a Layer-by-Layer fashion to build up thin films of polymers. While this polymer coating is a well-developed technique, the quantification of polymers deposited and physical mechanism of polymer deposition remain relatively unstudied. In this work CTAB capped gold nanoparticles, synthesized in a flow reactor, are coated with sodium polystyrene sulfonate and purified through a series of equilibrium dialysis steps...

This study examines the role of regional government quality in health-related participation in sport and physical activity among adults (18-64 years) in 28 European countries. The importance of the analysis rests in the relative autonomy that regional and local governments have over policy decisions connected with sport and physical activity. While existing studies have focussed on economic and infrastructural investment and expenditure, this research investigates the quality of regional governments across 208 regions within 28 European countries...

BACKGROUND: Cardiovascular disease is a common health problem resulting from many factors, including dyslipidemia. T'ai chi is one of the interventions assigned to improve lipid profiles and other physical outcomes. However, conflicting results might be attributed to different study designs and interventional approaches. A systematic review and meta-analysis are needed to evaluate existing evidence. OBJECTIVE: The aim of this systematic review and meta-analysis is to evaluate existing randomized clinical trials (RCTs) regarding the overall effect of t'ai chi exercise on lipid profiles...

Popliteal artery entrapment syndrome is a condition in which compression of the popliteal neurovascular structures results in symptoms of lower extremity claudication by way of a constricting anatomic structure or a hypertrophied surrounding musculature. This diagnosis is often missed or misdiagnosed because popliteal artery entrapment syndrome has a presentation similar to that of exertional compartment syndrome. Popliteal artery entrapment syndrome may result in persistent disability or unnecessary morbidity or prevent athletes' return to sport...

Glomus tumors are small, benign tumors that arise from glomus bodies, structures found normally within the dermis that assist in temperature regulation via their vasoconstrictive response to sympathetic stimuli. Glomus tumors are found typically in the hand and are classically a cause of focal pain and temperature sensitivity. They often present as a small blue lesion seen under the nail bed of a finger or a toe and cause point tenderness. Glomus tumors of peripheral nerves are exceedingly rare and can lead to disability akin to compressive neuropathy when present...

Synthetic gene circuits allow the behavior of living cells to be reprogrammed, and non-coding small RNAs (sRNAs) are increasingly being used as programmable regulators of gene expression. However, sRNAs (natural or synthetic) are generally used to regulate single target genes, while complex dynamic behaviors would require networks of sRNAs regulating each other. Here, we report a strategy for implementing such networks that exploits hybridization reactions carried out exclusively by multifaceted sRNAs that are both targets of and triggers for other sRNAs...

The antibacterial effect of a nanostructured film, known as "moth-eye film," was investigated. The moth-eye film has artificially formed nano-pillars, consisting of hydrophilic resin with urethane acrylate and polyethylene glycol (PEG) derivatives, all over its surface that replicates a moth's eye. Experiments were performed to compare the moth-eye film with a flat-surfaced film produced from the same materials. The JIS Z2801 film-covering method revealed that the two films produced a decrease in Staphylococcus aureus and Esherichia coli titers of over 5 and 3 logs, respectively...

STUDY GOALS: To describe the differences between clients presenting after rape and clients who have consented to sex as a minor to an SGBV clinic in Harare, Zimbabwe, and how these differences affect their care requirements. BACKGROUND: Adolescents and adults presenting at the specialized Sexual and Gender Based Violence clinic in Harare are offered a standardised package of free medical and psychosocial care. Zimbabwe has an HIV prevalence of 14%, so prevention of HIV infection using PEP for those that present within 72 hours is a key part of the response...

Jonathan A Kemp
The physics of wound and unwound strings on the electric guitar are presented here, and the pitch intervals produced by the movements of a Fender Stratocaster tremolo unit are explained. Predicted changes in pitch sensitivity of different strings are given, and experimentally verified, for changes in saddle height, the distance of string free to move behind the nut and ratio of diameters/masses of the core and windings of wound strings. Also, it is shown that changes to the gauge of strings (assuming the string tension is sufficient for linear behaviour and in absence of changes to other construction details) don't alter the pitch intervals produced by a given angle of tremolo arm use assuming the instrument is set up with the same sounding pitches and starting bridge angle...

BACKGROUND: Cerebral Palsy (CP) is the most common physical pediatric neurodevelopmental disorder and spastic diplegic injury is its most frequent subtype. CP results in substantial neuromotor and cognitive impairments that have significant socioeconomic impact. Despite this, its underlying pathophysiological mechanisms and etiology remain incompletely understood. Furthermore, there is a need for clinically relevant injury models, which a) reflect the heterogeneity of the condition and b) can be used to evaluate new translational therapies...

There is mounting evidence that aerobic exercise has a positive effect on cognitive functions in older adults. To date, little is known about the neurometabolic and molecular mechanisms underlying this positive effect. The present study used magnetic resonance spectroscopy and quantitative MRI to systematically explore the effects of physical activity on human brain metabolism and grey matter (GM) volume in healthy aging. This is a randomised controlled assessor-blinded two-armed trial (n=53) to explore exercise-induced neuroprotective and metabolic effects on the brain in cognitively healthy older adults...
