Leisure activity participation is important for health and well-being. This study examined similarities and differences between typically developing children and those with autism spectrum disorders (ASD) from 6 to 17 years old in physical, recreational, social, skill, and jobs/chores activities from a large national database. Findings revealed that children with ASD had significantly lower participation levels than those without ASD between 11 and 17 years old. They suggest an increasing disparity among many types of leisure participation for children and youth with ASD as they age, eventually leading to limited participation in adult activities...

Due to the significant role of the periosteum in bone regeneration, we hypothesised that using a specially engineered artificial periosteum could lead to an enhancement in osteogenesis in bone grafts. Herein, we describe our work aimed at fabricating an electrospun fibrous membrane as an artificial periosteum that exhibits flexibility, permeability and osteoinduction. This membrane was designed to cover the complex surface of bone grafts to facilitate and accelerate bone regeneration. The traditional Chinese medicine icariin (ICA) was subsequently introduced into poly (ε-caprolactone) (PCL) /gelatin nanofibers to fabricate an artificial periosteum for the first time...

Extended periods of skeletal muscle disuse result in muscle atrophy. Following limb immobilization, increased mitochondrial reactive oxygen species (ROS) production may contribute to atrophy through increases in skeletal muscle protein degradation. However, the effect of skeletal muscle disuse on mitochondrial ROS production remains unclear. This study investigated the effect of immobilization, followed by two subsequent periods of restored physical activity, on mitochondrial H2 O2 emissions in adult male skeletal muscle...

Why? The potential risks of sport for an ICD recipient include appropriate and inappropriate shocks, device damage and worsening of the underlying cardiopathy. These risks should be compared to the physical and psychological benefits of exercise. Where? Due to different medico-legal contexts and considering the results of recent studies, the new US guidelines are more permissive than the European guidelines regarding sport practice in ICD recipients. Who? The underlying context (structural or electrical cardiopathy, psychological impact) should be assessed before any decision is taken...

The over discharge of mine tailing cause consequent heavy metal pollution. Phytoremediation as one of the most viable and efficient method for this problem has aroused much attention. In this research, the growth and physiological responses of Suaeda glauca and Arabidopsis thaliana plants were investigated, and the soil conditions (pH and enzyme activity) were evaluated further under varied levels of cadmium (Cd), lead (Pb) and manganese (Mn). The results showed that heavy metals could inhibit the growth of plants...

PURPOSE: Surgery for nontraumatic upper-extremity problems is largely discretionary and preference-sensitive. Psychological and social determinants of health correlate with greater symptoms and limitations and might be associated with discretionary operative treatment. METHODS: We used routinely collected patient-reported outcome measures from patients with de Quervain tendinopathy, ganglion cyst, trapeziometacarpal arthritis, trigger digit, and carpal tunnel syndrome to study factors associated with discretionary surgery using multiple logistic regression...

Macular xanthophylls (MXs) are distinguished from other dietary carotenoids by their high membrane solubility and preferential transmembrane orientation. Additionally, these properties enhance the chemical and physical stability of MXs in the eye retina, and maximize their protective activities. The effectiveness of MXs' protection is also enhanced by their selective accumulation in the most vulnerable domains of retinal membranes. The retina is protected by MXs mainly through blue-light filtration, quenching of the excited triplet states of potent photosensitizers, and physical quenching of singlet oxygen...

BACKGROUND: Frailty is associated with older age and multimorbidity (two or more long-term conditions); however, little is known about its prevalence or effects on mortality in younger populations. This paper aims to examine the association between frailty, multimorbidity, specific long-term conditions, and mortality in a middle-aged and older aged population. METHODS: Data were sourced from the UK Biobank. Frailty phenotype was based on five criteria (weight loss, exhaustion, grip strength, low physical activity, slow walking pace)...

BACKGROUND: Health inequalities persist into old age. We aimed to investigate risk factors for socioeconomic differences in frailty that could potentially be modified through policy measures. METHODS: In this multi-wave longitudinal cohort study (Whitehall II study), we assessed participants' socioeconomic status, behavioural and biomedical risk factors, and disease status at age 45-55 years, and frailty (defined according to the Fried phenotype) at baseline and at one or more of three clinic visits about 18 years later (mean age 69 years [SD 5·9])...

The Marano and Grado Lagoon is well known for being contaminated by mercury (Hg) from the Idrija mine (Slovenia) and the decommissioned chlor-alkali plant of Torviscosa (Italy). Experimental activities were conducted in a local fish farm to understand Hg cycling at the sediment-water interface. Both diffusive and benthic fluxes were estimated in terms of chemical and physical features. Mercury concentration in sediments (up to 6.81μg/g) showed a slight variability with depth, whereas the highest methylmercury (MeHg) values (up to 10ng/g) were detected in the first centimetres...

In this study, coupling of ultrasound (US) device and rotor-stator (RS), operating at low-energy densities, was studied as an alternative process to individual US and RS to produce modified starch-stabilized oil-in-water emulsions, as well as its potential use to encapsulate eugenol. To this aim, a full factorial design was employed to evaluate the effects of the US nominal power (0, 360 and 720 W) and RS nominal power (0, 150 and 300 W) on the physical properties, encapsulation efficiency and kinetic stability of emulsions produced...

More than 80% of the global population depends on traditional medicine for their basic primary health care needs. Africa has a well-established history of botanicals use. These include a vast array of compounds that can be used to treat various skin-related conditions. The rationale for the use of traditional medicine in skincare stems from the physical effects these compounds have on skin, such as the ability to control bleeding and speed up wound healing, as well as the potential to treat burns and other disorders of pigmentation...

OBJECTIVE: Although physical activity (PA) is associated with a reduction of a wide range of sleep problems, it remains uncertain whether complying with the international guidelines of 150 min of moderate to vigorous PA per week can reduce sleep problems in adults. This research investigated the relationship between compliance with the PA recommendations of the World Health Organization and sleep problems in 38 low- and middle-income countries (LMICs). METHODS: Cross-sectional, community-based data from the World Health Survey were analyzed...

There is a growing interest in preclinical research to consider low-dose metronomic chemotherapy as antiangiogenic cancer treatment. Oral metronomic therapy, in particular, has shown much promise with its ease of daily administration and higher therapeutics window. In that regard, we developed oral pemetrexed using the physical complex with the bile acid enhancers (DCK). In a caco-2 permeability study, the oral pemetrexed/DCK complex had significantly higher drug uptake, and inhibited efflux transporter activity as well...

Neighborhood parks help women engage in physical activity (PA). We used the physical activity resources assessment instrument to determine the availability, quality and quantity of physical features, and amenities in 19 neighborhood parks randomly selected from the Jackson, Mississippi, Metropolitan Statistical Area. Madison County averaged the most quality PA features (mean, 13) and quality PA amenities (mean, 25.8), and it averaged the least quality incivilities (mean, 1.6). The total neighborhood parks quality physical activity resources (QPAR) was determined by a composite index QPAR of features, amenities, and incivilities...

Plant heterotrimeric G proteins modulate numerous developmental stress responses. Recently, receptor-like kinases (RLKs) have been implicated as functioning with G proteins, and may serve as plant G-protein-coupled-receptors (GPCRs). The RLK FERONIA (FER), in the Catharantus roseus RLK1-like subfamily, is activated by a family of polypeptides called Rapid Alkalinization Factors (RALFs). We previously showed that the Arabidopsis G protein β subunit, AGB1, physically interacts with FER, and that RALF1 regulation of stomatal movement through FER requires AGB1...

: media-1vid110.1542/5778442247001PEDS-VA_2017-4085 Video Abstract BACKGROUND AND OBJECTIVES: Shorter sleep duration is associated with childhood obesity. Few studies measure sleep quantity and quality objectively or examine cardiometabolic biomarkers other than obesity. METHODS: This cross-sectional study of 829 adolescents derived sleep duration, efficiency and moderate-to-vigorous physical activity from >5 days of wrist actigraphy recording for >10 hours/day. The main outcome was a metabolic risk score (mean of 5 sex-specific z-scores for waist circumference, systolic blood pressure, high-density lipoprotein cholesterol scaled inversely, and log-transformed triglycerides and homeostatic model assessment of insulin resistance), for which higher scores indicate greater metabolic risk...
