The most common injuries, rehabilitation and recovery among soccer practitioners

Introduction. Soccer is the most popular sport in the world. As a contact sport it has a high risk and incidence of injuries, which most often affect the lower limb. For the player to recover it is neessary to attend to well planned rehabilitation. Purpose. Analyzing the most common injuries among people practicing soccer and determining the role of rehabilitation in the treatment of these injuries.Material and methods. The research group was 101 individuals, 88 male and 13 female who played soccer as amateurs or professionals, aged 10 to 45 and had been training for a minimum of 2 years.Results. There were 487 injuries in total among all respondents, of which 370 were related to the lower limb and 117 to the upper body. Contussions and ankle sprains were the most common injuries. Every single preson included in the studies suffered from injury, but only 75.2% of them went to see a doctor after the incident and  only  56,4% attended rehabilitation.  Statistical significance has been present in the time to return to sports depending on the continuation of physical exertion after the injury, in the time to return to sport due to treatment or the lack of it, in the time to return to sports in relation to whether or not rehabilitation took place for patients with serious injury.Conclusion. The most common sports injuries in soccer are lower limb injuries, including damage to muscles and tendons. Recovery time is related to the type of injury, treatment options and rehabilitation methods. People practicing soccer should monitor their training loads with a physiotherapist. This can reduce the amount of problems later in career or daily life.Abstract Introduction. Soccer is the most popular sport in the world.

Photoluminescence of ZnBeMnSe solid solutions

In this paper optical properties of Zn1-x-yBexMnySe mixed semiconductors were studied as a function of both, temperature and excitation power. The crystals under investigation were grown by the high-pressure, high-temperature vertical Bridgman technique within the range of the composition 0.05 ≤ x,y ≤ 0.2. Photoluminescence spectra for the lowest content of Mn and Be exhibit character typical for II-VI semiconductors together with intensive yellow-orange manganese emission. Evolution of the excitonic emission as the function of temperature allowed determining the energy gap of the investigated semiconductors. Absorbance and photoluminescence excitation spectra confirmed crystal field splitting of excited atomic terms of manganese ions into the states, denoted according to the crystal field theory in the case of tetrahedral symmetry. Temperature and laser power dependences of luminescence showed anomalous behavior of the manganese emission. It turned out that the position of the Mn2+ related luminescence band does not change monotonically with the variation of the temperature or the excitation power. Finally, switching of the manganese emission has been observed. By increasing laser power of exciting radiation, the Mn-related emission could be quenched by almost two orders in magnitude. This effect was especially strong at low temperature and it was fully reversible

Thermal characterization of II–VI binary crystals by photopyroelectric calorimetry and infrared lock-in thermography

In this paper, a complete thermal characterization (measurement of all static and dynamic thermal parameters) of some selected II-VI binary crystals was carried out. The semiconductors under investigation were grown from the melt by high-pressure/high-temperature modified Bridgman method. The contact photopyroelectric (PPE) method in back configuration (BPPE) and non-contact infrared lock-in thermography technique were used in order to get the thermal diffusivity of the investigated crystals. The thermal effusivity of the samples was obtained by using the PPE technique in the front configuration (FPPE), together with the thermal wave resonator cavity (TWRC) method. Knowing the values of the thermal effusivity and thermal diffusivity, the remaining two thermal parameters, i.e., thermal conductivity and specific heat were calculated

9-(3-Fluoro­phen­oxy­carbon­yl)-10-methyl­acridinium trifluoro­methane­sulfonate monohydrate

In the crystal structure of the title mol­ecular salt, C21H15FNO2 +·CF3SO3 −·H2O, the cations form inversion dimers through π–π inter­actions between the acridine ring systems. These dimers are linked via C—H⋯O and C—F⋯π inter­actions to adjacent anions, and by C—H⋯π and C—F⋯π inter­actions to neighbouring cations. The water mol­ecule links two sites of the cation by C—H⋯O inter­actions and two adjacent anions by O—H⋯O hydrogen bonds. The mean planes of the acridine and benzene ring systems are oriented at a dihedral angle of 15.1 (1)°. The carboxyl group is twisted at an angle of 84.5 (1)° relative to the acridine skeleton. The mean planes of the acridine ring systems are parallel in the crystal

Qualitative analysis of phospholipids and their oxidised derivatives - used techniques and examples of their applications related to lipidomic research and food analysis.

Phospholipids (PLs) are important biomolecules that not only constitute structural building blocks and scaffolds of cell and organelle membranes but also play a vital role in cell biochemistry and physiology. Moreover, dietary exogenous PLs are characterised by high nutritional value and other beneficial health effects, which are confirmed by numerous epidemiological studies. For this reason, PLs are of high interest in lipidomics that targets both the analysis of membrane lipid distribution as well as correlates composition of lipids with their effects on functioning of cells, tissues and organs. Lipidomic assessments follow-up the changes occurring in living organisms, such as free radical attack and oxidative modifications of the polyunsaturated fatty acids (PUFAs) build in PL structures. Oxidised PLs (oxPLs) can be generated exogenously and supplied to organisms with processed food or formed endogenously as a result of oxidative stress. Cellular and tissue oxPLs can be a biomarker predictive of the development of numerous diseases such as atherosclerosis or neuroinflammation. Therefore, suitable high-throughput analytical techniques, which enable comprehensive analysis of PL molecules in terms of the structure of hydrophilic group, fatty acid (FA) composition and oxidative modifications of FAs, have been currently developed. This review addresses all aspects of PL analysis, including lipid isolation, chromatographic separation of PL classes and species, as well as their detection. The bioinformatic tools that enable handling of a large amount of data generated during lipidomic analysis are also discussed. In addition, imaging techniques such as confocal microscopy and mass spectrometry imaging for analysis of cellular lipid maps, including membrane PLs, are presented

Cranioplasty as neurosurgical procedure with potential risk of legal claims

We present the current state of affairs regarding the legal claims of patients after cranioplasty operations who are dissatisfied with the treatment effect and have claims that the perioperative course is unfavorable. In the period of 11 years (2010-2020), 2 legal claims were submitted in our neurosurgical center after cranioplasty. Both are civil claims. One of them about purulent infection of the bone prosthesis was found by the judgment to be unfounded. The second one concerning the alleged general condition deterioration as a consequence of cranioplasty has been declared obsolete. A cranioplasty is a surgical procedure used to correct a defect in a bone of the skull. It is not urgent sugery and is performed in patients who had been previously in serious condition. The same medical staff who previously saved the live of patients by performing brain decompression may be subject of legal claims in the case of cranioplasty. Thus, according to authors, claims of patients regarding the alleged negative effects of cranioplasty is an interesting psychological phenomenon.  Authors epmhasized that cranioplasty should be considered as a procedure of increased risk of potential legal claims for medical staff

Point-of-Care Testing – Biosensor for Norepinephrine Determination

An useful electrochemical sensing approach was developed for norepinephrine (NE) detection based on semiconducting polymer (9-nonyl-2,7-di(selenophen-2-yl)-9H-carbazole) and laccase modified platinum electrode (Pt). The miniature Pt biosensor was designed and constructed via  the immobilization of laccase in an electroactive layer of the electrode coated with thin polymeric film. This sensing arrangement utilized the catalytic oxidation of NE to norepinephrine quinone. The detection process was based on the oxidation of catecholamine in the presence of enzyme – laccase. With the optimized conditions, the analytical performance demonstrated selectivity in a wide linear range (0.1–200x10-6 M) with a detection limit of 240 nM and a quantification limit of 365 nM. Moreover, the method was successfully applied for selective NE determination in the presence of interfering substances
