Background: The injuries sustained in football most frequently occur to the lower extremity, with ankle and knee being the most affected joint segments. Many studies have defined ankle sprain as one of the most common sports injuries with an annual incidence rate of 15% to 45%, however, there’s a lack of studies in football regional leagues. Risk factors like anthropometric measures, field position, dominant limb, previous injury have been described as being associated with ankle injuries in the elite sports context. The primary aim of this study was to determine prevalence rates of self-reported ankle instability in regional leagues. A secondary aim was to explore the presence of extrinsic factors affecting ankle instability in these football players. Methods: The heads of all clubs (n = 66) from Coimbra and Aveiro (Portugal) regional male senior football divisions during season 2016/2017 were contacted by e-mail or telephone to enter the study, and 58 gave their permission to include their athletes. Then, all players from each of these 58 teams were invited to enter the study (n = 1044) and a total of 589 athletes participated. Demographic and anthropometric data were recorded concerning age, height, weight, years of training, mean number of training hours, position in camp along with specific questions related to an ankle injury. All participants were asked about their previous history of injury, reinjury, feeling of giving-away and where also asked to fill the Cumberland Ankle Instability Tool. Results: A total of 290 (49.2%) athletes reported a history of at least one previous sprain and, from these, 170 (58.6%) repeated the injury and 112 (19%) reported sensation of “giving-away”. A significant association was found between injury, recurrence and subjective feeling of giving away (p n was found to be associated with ankle instability, with defenders and forwards having higher rates of self-reported instability. no other signi

Worldwide, diabetes is affecting 370 million people, causing nearly five million deaths and absorbing more than 471 billion USD per year. Mathematical models have been developed to simulate, analyse and understand the dynamics of β-cells, insulin and glucose. In this paper, we consider the effect of genetic predisposition to diabetes on dynamics of β-cells, glucose and insulin. We assume that the β-cell dynamics is governed by the differential equation: . The model indicates different behaviours according to the presence or absence of genetic predisposition. In presence of predisposition (ε = 1), the model shows three equilibrium points: a stable physiological equilibrium point (g = 100, I = 20, β = 600), a stable trivial pathological equilibrium point (g = 600, I = 0, β = 0) and a saddle point (g = 250, I = 9.8, β = 129.36). In absence of predisposition (ε = 0), the model has only two equilibrium points: an unstable pathological equilibrium point (g = 600, I = 0, β = 0) and a stable physiological equilibrium point (g = 82.6, I = 23, β = 900). In order to see how physical activity, obesity and other factors affect insulin sensitivity, simulations are carried out with different values of insulin induced glucose uptake rate (c), β-cell maximum insulin secretory rate (d) and environmental capacity (K).

Resting spores are important in ecology and taxonomy of diatoms as well known to every dia-tomist. If nO3-n and nO2-n in the cultures drop down to 4 μg I-1, or at a relatively small amount of n, higher in number of individuals and sudden increasing of salinity, the resting spores will produce after 24 h. Paired spores are present in the newborn spore-mother cells. At 20℃ and 6000 lx in a fresh medium, spores will be germinated into vegetative cells within 48 h.

Expected Radial Column Density of Methylcyanopolyynes in CW Leonis (IRC+10216)

引用

International Journal of Astronomy and Astrophysics 2015年第3期5卷 141-147页

作者： Raul g. E. Morales Carlos Hernández Centre for Environmental Sciences and Department of Chemistry Faculty of Sciences Universidad de Chile Santiago Chile Department of Chemistry Faculty of Basic Sciences Universidad Metropolitana de Ciencias de la Educación Santiago Chile

Methylcyanopolyynes (CH3-[C≡C]n-Cn) are a particular kind of linear molecular wires, where the first three oligomers have been detected in the interstellar medium, particularly in CW Leonis (IRC + 10216), as well as in the envelopes of carbon-rich stars in a similar way to the unsubstituted cyanopolyynes. Based on the projected natural distribution in cold clouds under LTE, we have determined the radial column density of new expected methylcyanopolyynes to be present in CW Leonis (IRC + 10216). By following, we have made use of the inner molecular resistances of the internal charge transfer process presenting in these oligomeric species in order to determine the reactivity trends between them. Therefore, geometrical parameters and dipole moments determinations for these methylcyanopolyynes involving the n = 1 to 14 molecular species were obtained from Ab initio molecular orbital calculations by means of a gAUSSIAn Program, using a restricted Hartree-Fock approach and 6-311g* basis set. Our results present a similar behavior observed in cyanopolyynes, where this series reaches a saturation level at the 14th oligomer with a maximum dipole moment of 8.21 ± 0.01 (Debyes). Thus, this molecular wire model permits us to comprehend how these methylcyanopolyynes reach a maximum length in such chemical environment, in agreement to the astronomical observations and cosmological chemical models. The following CH3C9n and CH3C11n oligomers in CW Leonis should be expected near to 3.52 × 1010 [cm2] and 1.82 × 1010 [cm2], respectively.

let g be an Abelian group and letρ：g×g→[0,∞） be a metric on g. let E be a normed space. We prove that under some conditions if f：g→E is an odd function and Cx：g→E defined by Cx（y）：=2 f （x＋y）＋2 f （x-y）＋12 f （x）-f （2x＋y）-f （2x-y） is a cubic function for all x∈g, then there exists a cubic function C：g→E such that f？C is Lipschitz. Moreover, we investigate the stability of cubic functional equation 2 f （x＋y）＋2 f （x-y）＋12 f （x）-f （2x＋y）-f （2x-y）=0 on Lipschitz spaces.

Background: The effect of obstructive sleep apnoea-hypopnoea as a cardiovascular risk factor and the potential protective effect of its treatment with continuous positive airway pressure (CPAP) is unclear. We did an observational study to compare incidence of fatal and non-fatal cardiovascular events in simple snorers, patients with untreated obstructive sleep apnoea-hypopnoea, patients treated with CPAP, and healthy men recruited from the general population. Methods: We recruited men with obstructive sleep apnoea-hypopnoea or simple snorers from a sleep clinic, and a population-based sample of healthy men, matched for age and body-mass index with the patients with untreated severe obstructive sleep apnoea-hypopnoea. The presence and severity of the disorder was determined with full polysomnography, and the apnoea-hypopnoea index (AHI) was calculated as the average number of apnoeas and hypopnoeas per hour of sleep. Participants were followed-up at least once per year for a mean of 10.1 years (SD 1.6) and CPAP compliance was checked with the built-in meter. Endpoints were fatal cardiovascular events (death from myocardial infarction or stroke) and non-fatal cardiovascular events (non-fatal myocardial infarction, non-fatal stroke, coronary artery bypass surgery, and percutaneous transluminal coronary angiography). Findings: 264 healthy men, 377 simple snorers, 403 with untreated mild-moderate obstructive sleep apnoea-hypopnoea, 235 with untreated severe disease, and 372 with the disease and treated with CPAP were included in the analysis. Patients with untreated severe disease had a higher incidence of fatal cardiovascular events (1.06 per 100 person-years) and non-fatal cardiovascular events (2.13 per 100 person-years) than did untreated patients with mild-moderate disease (0.55, p=0.02 and 0.89, p norers (0.34, p=0.0006 and 0.58, p nts treated with CPAP (0.35, p=0.0008 and 0.64, p nd healthy participants (0.3, p=0.0012
