Despite approval of the use of electronic personal tracking devices (EPTD) during competition by the International Football Association Board (IFAB), other team sport organizations and leagues have banned its use due to "safety concerns", with no evidence to support this assertion. The aim of the current brief report is to provide empirical evidence to support the wide-spread usage across all sports by examining safety issues concerning the use of EPTD in a multi-team sports club. A total of 5 outdoor football teams (first team, second team, under 19, under 18 and first team female) and 3 indoor multi-sport (basketball, futsal and handball) teams have been monitored; accounting for a total of 63...

Although diuretics have been widely used to treat hypertension along with others cardiovascular and renal disorders, no scientific data have been recorded to support the diuretic properties of Rubus rosaefolius Sm. (Rosaceae), a plant popularly used in Brazil to treat hypertension. Male Wistar rats were orally treated with: vehicle; hydrochlorothiazide; aqueous (AERR) and methanolic (MERR) extracts; dichloromethane (DCM), hexane (HEX) and ethyl acetate (EA) fractions; and the isolated compounds 2α,3β,19α-trihydroxy-urs-12-en-28-oic acid (TUA) and 5-hydroxy-3,6,7,8,4'-pentamethoxyflavone (PMF)...

Multivariate Adaptive Regression Splines (MARS) is a non-parametric modelling method that extends the linear model, incorporating nonlinearities and interactions between variables. It is a flexible tool that automates the construction of predictive models: selecting relevant variables, transforming the predictor variables, processing missing values and preventing overshooting using a self-test. It is also able to predict, taking into account structural factors that might influence the outcome variable, thereby generating hypothetical models...

The development of Ti alloys to manufacture dental implants has emerged in recent years due to the increased failure of commercially pure titanium (cpTi) implants. Thus, this study reviews existing information about the mechanical, chemical, electrochemical, and biological properties of the main Ti alloys developed over the past few years to provide scientific evidence in favor of using Ti-based alloys as alternative to cpTi. Ti alloys may be considered viable substitutes in the fabrication of dental implants...

The study aimed to identify whether payment forms and insurance schemes are associated with severe obstetric complications and maternal mortality. A hospital-based case-control study was conducted in two regions of Colombia, 2009-2011. Data were obtained from each woman's clinical history. Unconditional logistic regression was used. The sample included 1,011 patients: 337 cases and 674 controls. No quality component was statistically significant in either region. In Bogotá, the risk of obstetric complications was significantly higher in the contributive insurance scheme than in subsidized coverage or uninsured; Antioquia showed similar associations, but not statistically significant...

As the incidence of water deficit and heat stress increases in many production regions there is an increasing requirement for crops adapted to these stresses. Thus it is essential to match water supply and demand, particularly during grain-filling. Here we integrate Grime's ecological strategies approach with traditional drought resistance/yield component frameworks describing plant responses to water deficit. We demonstrate that water use is a function of both short and longer term trade-offs between competing demands for carbon...

Patients with chronic kidney disease (CKD) develop bleeding and thrombotic tendencies, so the indication of anticoagulation at the onset of atrial fibrillation (AF) is complex. AF is the most common chronic cardiac arrhythmia, and thromboembolism and ischemic stroke in particular are major complications. In recent years, new oral anticoagulant drugs have been developed, and they have shown superiority over the classical AVK in preventing stroke, systemic embolism and bleeding risk, constituting an effective alternative to those resources...

Eukaryotic DNA replication initiates from multiple discrete sites in the genome termed origins of replication (origins). Prior to S phase, multiple origins are poised to initiate replication by recruitment of the pre-replicative complex (pre-RC). For proper replication to occur, origin activation must be tightly regulated. At the population level, each origin has a distinct firing time and frequency of activation within S phase. Many studies have showed that chromatin can strongly influence initiation of DNA replication...

Nine new methylated galloylquinic acids were isolated from an aqueous fraction of Copaifera langsdorffii (Fabaceae-Caesalpinioideae) leaf hydroalcoholic extract (3-8, 11, 12, and 14), along with three known methylated galloylquinic acids (1, 2, and 15) and four galloylquinic acids (9, 10, 13, and 16). These compounds were characterized by nuclear magnetic resonance spectroscopy and mass spectrometry. They were further tested in a gastroprotection assay (Ethanol-HCl induced ulcer model in mice), in which all of them significantly reduced the total lesion area, and increased the cure ratio in comparison with pantoprazole...

A series of pyrazolo[3,4-b]pyridines were prepared by a microwawe-assisted aza-Diels-Alder reaction between pyrazolylformimidamides 1 and β-nitrostyrenes 2 in toluene as the solvent. This procedure provides a simple one-step and environmentally friendly methodology with good yields for the synthesis of these compounds. All compounds were tested for antifungal activity against two clinically important fungi Candida albicans and Cryptococcus neoformans. Within the compounds of the series bearing a -CH3 group on the carbon C-3 of the azole ring (3a-3e), the compound without a substituent on the p'-phenyl ring (3a), showed the best activity against both fungi, followed by the p'-Br-phenyl (3c)...

Diagnosis of infection with Leishmania infantum by DNA detection in the hair has been recently demonstrated in dogs and wild animals. Our objective was to investigate if polymerase chain reaction (PCR) in hair might be used to identify infectious dogs. Thus, we assessed the infectiousness to Lutzomyia longipalpis by xenodiagnosis in comparison with the detection of L. infantum DNA by PCR in the hair, and with serology for anti-Leishmania IgG by ELISA in 15 positive dogs for L. infantum infection. Eight healthy dogs were included as negative controls...

Tropically adapted Bos taurus breeds are descended from the cattle which were brought from the Iberian Peninsula to Latin America by the colonizers and which adapted over time to local conditions. These breeds have become a genetic treasure that must be preserved. The objective of this study was to characterize ovarian follicular emergence and divergence in tropically adapted B. taurus cows and heifers. Cyclic heifers (n = 11) and nonlactating, multiparous cows (n = 11) were examined at 8-hour intervals using ultrasonography starting on the day following the final application of PGF2α, which was used to synchronize the estrous cycle, and ending 5 days after ovulation...

Almost 30% of adult patients with attention-deficit/hyperactivity disorder (ADHD) do not respond or tolerate standard pharmacological interventions. Few clinical investigations addressed the efficacy and tolerability of transcranial direct current stimulation (tDCS), a non-invasive neuromodulatory technique, in the disorder. We performed a double-blind, sham-controlled randomized clinical trial in 17 patients with ADHD. The set up for tDCS was the following: 2mA/20min/day for 5 days with the anode over the right dorsolateral prefrontal cortex and cathode over the left dorsolateral prefrontal cortex...

This study reports the use of the U-series radionuclides (238)U and (234)U for dating two soil profiles. The soil horizons developed over sandstones from Tatuí and Pirambóia formations at the Paraná sedimentary basin, São Paulo State, Brazil. Chemical data in conjunction with the (234)U/(238)U activity ratios (AR's) of the soil horizons allowed investigating the U-isotopes mobility in the shallow oxidizing environment. Kaolinization and laterization processes are taking place in the profiles sampled, as they are especially common in regions characterized by a wet and dry tropical climate and a water table that is close to the surface...
