REVIEW
Weiwei Fan, Ronald M Evans
The global epidemic of obesity and its associated chronic diseases is largely attributed to an imbalance between caloric intake and energy expenditure. While physical exercise remains the best solution, the development of muscle-targeted "exercise mimetics" may soon provide a pharmaceutical alternative to battle an increasingly sedentary lifestyle. At the same time, these advances are fueling a raging debate on their escalating use as performance-enhancing drugs in high-profile competitions such as the Olympics...

BACKGROUND: Presenteeism is a growing problem in developed countries mostly due to an aging workforce. The economic costs related to presenteeism exceed those of absenteeism and employer health costs. Employers are implementing workplace health promotion and wellness programs to improve health among workers and reduce presenteeism. How best to design, integrate and deliver these programs are unknown. The main purpose of this study was to use an intervention mapping approach to develop a workplace health promotion and wellness program aimed at reducing presenteeism...

Isomerism, also known as heterotaxy, is a clinical entity that impacts multiple organ systems both anatomically and functionally. The airways and lungs are involved in a great number of these patients, leading to increased sinopulmonary symptoms, increased need for oxygenation, and increased postoperative ventilatory support. Additionally, these patients often have congenital heart disease requiring Fontan palliation. What has not been previously described, and is the focus of this study, is the results of cardiopulmonary exercise testing in those who have undergone Fontan palliation with and without isomerism...

Guidelines for cardiovascular prevention need to be regularly revised and updated. With respect to physical activity and exercise, many studies with practical relevance have been published in recent years. They are concerned with the evidence of physical activity for prevention of many diseases and the spectrum of indications for applying physical activity for prevention, therapy and rehabilitation. Training recommendations have been developed for the prevention of various diseases according to the FITT rule, which stands for frequency, intensity, time (of session) and type of sports followed by a progression in the amount of training...

The influence of optically active turbulence on the propagation of laser beams is investigated in clear ocean water over a path length of 8.75 m. The measurement apparatus is described and the effects of optical turbulence on the laser beam are presented. The index of refraction structure constant is extracted from the beam deflection and the results are compared to independently made measures of the turbulence strength (Cn2) by a vertical microstructure profiler. Here we present values of Cn2 taken from aboard the R/V Walton Smith during the Bahamas optical turbulence exercise (BOTEX) in the Tongue of the Ocean between June 30 and July 12, 2011, spanning a range from 10<sup>-14</sup> to 10<sup>-10</sup>  m<sup>-2/3</sup>...

BACKGROUND: Intervertebral disc disease (IVDD) represents a major problem in the Dachshund, with at a relative risk of IVDD 10-12 times higher than other breeds, and an estimated 19-24 % of Dachshunds showing clinical signs related to IVDD during their lifetime. A variety of genetic, physical and lifestyle-related risk factors for IVDD have previously been identified, with some conflicting findings. As such, advising owners and breeders regarding best-practice for IVDD prevention is challenging at present...

Maximal oxygen uptake (VO2max) is an essential part of health and physical fitness, and refers to the highest rate of oxygen consumption an individual can attain during exhaustive exercise. In this study, for the first time in the literature, we combine the triple of maximal, submaximal and questionnaire variables to propose new VO2max prediction models using Support Vector Machines (SVM's) combined with the Relief-F feature selector to predict and reveal the distinct predictors of VO2max. For comparison purposes, hybrid models based on double combinations of maximal, submaximal and questionnaire variables have also been developed...

Exercise has been shown to be the best intervention in the treatment of many diseases. Many of the benefits of exercise are mediated by adaptions induced in skeletal muscle. The peroxisome proliferator-activated receptor gamma coactivator-1 (PGC-1) family of transcriptional coactivators has emerged as being key mediators of the exercise response and is considered to be essential for many of the adaptions seen in skeletal muscle. However, the contribution of the PGC-1s in skeletal muscle has been evaluated by the use of either whole body or congenital skeletal muscle-specific deletion...

PURPOSE OF REVIEW: Physical and cognitive frailty are interrelated and synergistic syndromes more frequently seen in old age, which represent intermediate stages between aging successfully and disability. Poor nutrition is a fundamental determinant for both conditions, while various dietary components are proposed to prevent and/or improve them. This updated review discusses the possible influence of nutritional factors on cognitive frailty and its potential mediators. RECENT FINDINGS: Oxidative stress, low-grade systemic inflammation, neuroinflammation, and altered autophagy, all associated with obesity, metabolic syndrome and insulin resistance, are proposed mechanisms to explain the influence of nutrition on cognitive health...

OBJECTIVE: Cerebral ischemia-reperfusion is the major pathophysiological process in stroke and can cause severe and lasting sequel. However, an intensive exercise training can potentially effect a quick and efficient recovery. We used swimming training on rats with cerebral ischemia-reperfusion (CIR) and explore the underlying neuroprotective mechanism(s), including the effects of intensive training on the expression of semaphorin 3A (Sema3A) and its receptor Neuropilin-1 (NRP-1). MATERIALS AND METHODS: The middle cerebral artery occlusion/reperfusion (MCAO/R) model was established by inserting a thread into the middle cerebral artery of Sprague-Dawley (SD) rats, and randomly dividing into the control group and training groups for different training intensities...
