Elaine C Rush, Mary R Yan
The increasing prevalence of obesity over the course of life is a global health challenge because of its strong and positive association with significant health problems such as type 2 diabetes, cardiovascular disease, stroke, and some cancers. The complex causes and drivers of obesity include genetic factors, social, ecological and political influences, food production and supply, and dietary patterns. Public health messages and government food and activity guidelines have little impact; the retail food environment has many low-priced, nutrient-poor, but energy-dense products and there is a gap between what an individual knows and what they do...

This study aimed to examine the validity of mechanical variables obtained by a linear velocity transducer from the unconstrained and constrained squat jump (SJ). Twenty-three men were tested on the unconstrained SJ and the SJ constrained by a Smith machine. Maximum values of force, velocity, and power were simultaneously recorded both by a linear velocity transducer attached to a bar of mass of 17, 30, 45, 60 and 75 kg and by a force plate. Linear velocity transducer generally overestimated the outcomes measured as compared to the force plate, particularly in unconstrained SJ...

S J Hamilton
Electrical impedance tomography (EIT) is an emerging imaging modality that uses harmless electrical measurements taken on electrodes at a body's surface to recover information about the internal electrical conductivity and or permittivity. The image reconstruction task of EIT is a highly nonlinear inverse problem that is sensitive to noise and modeling errors making the image reconstruction task challenging. D-bar methods solve the nonlinear problem directly, bypassing the need for detailed and time-intensive forward models, to provide absolute (static) as well as time-difference EIT images...

REVIEW
Aya Bar Oz
Ringworm of the scalp (Tinea Capitis), a fungal skin ailment that appears on the scalp, was treated until the early sixties by radiation therapy. It was discovered during the seventies that radiation treatment for ringworm may be associated with a higher risk of cancerous and benign tumors in the head and neck area for patients undergoing treatment. In 1995, Israel enacted a law to compensate ringworm irradiation patients which provided monetary compensation for those who were treated between 1946 and 1960...

Birds are an anomaly among vertebrates as they are remarkably long-lived despite having naturally high blood glucose and metabolic rates. For mammals, hyperglycemia leads to oxidative stress and protein glycation. In contrast, many studies have shown that domestic and wild birds are relatively resistant to these glucose-mediated pathologies. Surprisingly very little research has examined protein glycation in birds of prey, which by nature consume a diet high in protein and fat that promotes gluconeogenesis...

BACKGROUND: Despite recognition of the important role that governance and executive leaders play in ensuring patient safety and quality, little research has examined leaders' involvement in these areas beyond surveys that assess higher-level knowledge and understanding of patient and workforce safety concepts. METHODS: A survey was sent to a convenience sample of board members and CEOs, as well as unpaired safety and quality leaders (SQLs). The survey included approximately 36 questions asking board members and other non-CEO executives their knowledge, understanding, and board activities related to safety and quality, and SQLs their perceptions of their own boards' knowledge, understanding, and activities related to safety and quality...

Effective treatment of tannery wastewater prior to discharge to the environment as per environmental regulations remains a big challenge despite efforts to bring down the concentrations of the pollutants which are often quite high as measured in terms of chemical oxygen demand (7800 mg/L), total dissolved solids (5400 mg/L), chloride (4260 mg/L), sulphides (250 mg/L) and chromium. A pilot-scale forward osmosis and nanofiltration integrated closed loop system was developed for continuous reclamation of clean water from tannery wastewater at a rate of 52-55 L/m(2)/h at 1...

Oxidative stress plays an important role in both the initiation and progression of Parkinson's disease (PD). Rotenone, an environmental toxin, induces oxidative stress and impact mitochondrial dynamics, including fission and fusion. Thymoquinone (TQ) has been reported to have antioxidant and anti-inflammatory characteristics in vitro and in vivo. TQ scavenges free radicals so prevents cell damage against oxidative agents. To evaluate the efficacy of TQ in the management of PD, male Wistar rats (8-10 months) received rotenone...
