Criterion data for total energy expenditure (TEE) in elite rugby are lacking, which prediction equations may not reflect accurately. This study quantified TEE of 27 elite male rugby league (RL) and rugby union (RU) players (U16, U20, U24 age groups) during a 14-day in-season period using doubly labelled water (DLW). Measured TEE was also compared to estimated, using prediction equations. Resting metabolic rate (RMR) was measured using indirect calorimetry, and physical activity level (PAL) estimated (TEE:RMR)...

The further development of lithium-sulfur (Li-S) batteries is limited by the fact that the soluble polysulfide leads to the shuttle effect, thereby reducing the cycle stability and cycle life of the batteries. To address this issue,here a thin and lightweight (8 μm and 0.24 mg cm-2) reduced graphene oxide@MoS2 (rGO@MoS2) interlayer between the cathode and the commercial separator is developed as polysulfide barrier. The rGO plays the role as polysulfide physical barrier and an additional current collector, while the MoS2 have a high chemical adsorption for polysulfide...

In this study, avocado seed was successfully used as raw material for producing activated carbons by conventional pyrolysis. In order to determine the best condition to produce the activated carbons, a 22 full-factorial design of experiment (DOE) with three central points was employed by varying the temperature and time of pyrolysis. The two evaluated factors (temperature and time of pyrolysis) strongly influenced the SBET, pore volumes, hydrophobicity-hydrophilicity ratio (HI) and functional groups values; both factors had a negative effect over SBET, pore volumes and functional groups which means that increasing the values of factors leads to decrease of these responses; on the other hand, with regards to HI, both factors caused a positive effect which means that increasing their values, the HI has an enhancement over its values...

BACKGROUND: Evidence suggests that risk of colorectal and prostate cancer is increased among those with a family history of the same disease, particularly among first-degree relatives. However, the aggregation of colorectal and prostate cancer within families has not been well investigated. METHODS: Analyses were conducted among participants of the Women's Health Initiative (WHI) observational cohort, free of cancer at the baseline examination. Subjects were followed for colorectal cancer through August 31st, 2009...

BACKGROUND & AIMS: Use of aspirin and/or non-aspirin nonsteroidal anti-inflammatory drugs (NSAIDs) reduces the risk of several cancers, but it is not clear if use of these drugs is associated with risk of pancreatic cancer. METHODS: We evaluated aspirin and non-aspirin NSAID use and risk of pancreatic adenocarcinoma in 141,940 participants from the Health Professionals Follow-up Study and Nurses' Health Study using multivariable-adjusted Cox proportional hazards regression...

Extracts of Desmodium adscendens (Sw) DC are used for the treatment of various diseases but limited toxicological evaluations have been done on the medicinal plant. This study investigates toxicity effects of the leave extract of D adscendens, and the possibility of drug-drug interaction of the plant extract when co-administered with other drugs. Oral administrations of leaf extract of D adscendens to white Wistar rats in an acute toxicity studies allowed the estimation of an LD50 (median lethal dose) value of 1122 mg/kg body weight...

Nanodosimetry is a branch of dosimetry for investigation and modeling of the interaction pattern of ionizing radiation in nanometre site-sizes (at unit density), which dates back to the 1970's (Pszona S. A track ion counter. Proceedings of Fifth Symposium on Microdosimetry EUR 5452 d-e-f, Published by the Commission of the European Communities, Luxemburg, pp. 1107-1122 (1976)). To date, the different experimental approaches have lead to developing of three fully functional nanodosimeters: the Jet Counter operated at NCBJ, the Ion Counter operated at PTB and Startrack Counter operated at INFN-LNL...

Visceral leishmaniasis (VL) is the most severe form of leishmaniasis. Recent findings indicate that dendritic cells have a key role in the defense against the Leishmania parasite and that the activity of this cell may be modified by the eosinophil secretory protein eosinophil-derived neurotoxin (EDN). We hypothesized that the interactions between dendritic cells and EDN might be of importance in the disease development. Cellular content of EDN was analyzed by ELISA. The single-nucleotide polymorphisms at positions 405, 416, and 1122 in the EDN gene were analyzed by real-time PCR with TaqMan® reagents...

Polymetallic complexes with interesting multifunction have attracted extensive explorations. Induced by different anions of cobalt salts and solvents, five complexes CoII4CoIII3(H2L)3Cl5(MeOH) (1), [CoII4CoIII3(H2L)3(CH3COO)4(HCOO).H2O]n (2), [CoII4CoIII3(H2L)3(HCOO)4(NO3).2H2O]n (3), [CoII4CoIII3(H2L)3(BDA)(CH3COO)4.2H2O]n (4) and [CoII4CoIII3(H2L)3(IPA)(HCOO)3(DMF).H2O]n (5) (H6L = bis-tris propane; BDA = biphenyl-4,4'-dicarboxylic acid; IPA = isophthalic acid; DMF = N,N-dimethylformamide) based on heptanuclear {CoII4CoIII3} cluster with structures from 0D to 3D metal organic framework (MOF) have been solvothermally synthesized...

To identify active compounds in the roots of Euphorbia pekinensis for treatment of diabetic complications, an active column fraction from a 70% EtOH extract of E. pekinensis root was purified by preparative reversed-phase high-performance liquid chromatography, leading to the isolation of a new ellagic acid derivative, 3,3'-di-O-methylellagic acid 4-O-(6"-O-galloyl)-β-D-galactopyranoside (1), along with three known compounds, geraniin (2), 3,3'-di-O-methylellagic acid 4-O-β-D-xylopyranoside (3), and ellagic acid 3,3'-dimethyl ether (4)...

INTRODUCTION: Until recently, glaucoma requiring treatment was disqualifying for U.S. pilots and required an aeromedical special issuance waiver. Since 2013 Aerospace Medical Examiners (AMEs) have been authorized to evaluate third-class pilots with mild glaucoma using similar protocols and issue medical certificates without a waiver if these criteria specified in the AME Guide are met. METHODS: The FAA's medical database was searched for pilots with glaucoma between 2005 and 2014...

OBJECTIVES: Here we investigate breastfeeding and weaning practices and adult dietary habits at the Western Zhou Dynasty (1122-771 BC) site of Boyangcheng () located in Anhui Province, China. In addition, we utilize the differences in bone collagen turnover rates between rib and long bones from the same individual to examine past life histories, such as changes in diet or residence. MATERIALS AND METHODS: Bone collagen from both the rib and long bones (either femora or humeri) of 42 individuals was measured for stable isotope ratios of carbon (δ(13) C) and nitrogen (δ(15) N)...

Our objective was to clarify the effect of sleep curtailment on energy intake (EI) and physical activity under free-living conditions. Participants were 16 healthy women aged 21-22years. A randomized crossover trial design was used to compare a short sleep condition (SS): 4h/night (2:00-6:00) and a control sleep condition (CS): 7h/night (23:00-6:00). Each condition comprised 3 consecutive nights. Sleep duration was assessed using a wristwatch-type accelerometer at home. All living activities except sleeping were free-living...

OBJECTIVE: To evaluate the safety and efficacy of the addition of the cut-and-sew Maze III procedure (CSM) for mitral valve replacement (MVR) in patients with atrial fibrillation (AF) associated with rheumatic mitral valve disease (RMVD). METHODS: A total of 130 patients with persistent or long-standing persistent AF associated with RMVD were assigned at random to either the CSM plus MVR (Maze III) group or MVR alone (non-Maze) group. The primary endpoint was a composite of freedom from stroke and death at 1 year...

BACKGROUND: Crohn's disease (CD) negatively impacts patient quality of life and results in greater healthcare utilization. For pediatric CD patients, the burden also extends to their caregivers. We aimed to estimate work loss and productivity costs among caregivers of pediatric CD patients. METHODS: Data were from Truven MarketScan databases (2000-2012). Patients were <18 years old with ≥2 ICD-9 CD diagnostic codes. Controls were those without CD or ulcerative colitis and were matched to patients by age, Charlson Comorbidity Index, index year, and insurance plan category...
