Purpose. Many studies analyzing the game of tennis overlook assessing such variables as the pure ability to play the game or the skill needed to take an opponent by surprise. This can be quantified in terms of a player’s shot flexibility, variability, velocity, or by the conscious or intuitive adaptability one can possess towards anticipating return shots, how best to hit the ball in order to keep it in play, as well as the buildup of delivering a shot or in scoring a point. The aim of the study was to identify the ability to score points in tennis based on an original set of assessment criteria that were used to measure the different effective plays against an opponent. This included measuring the variability, spatial flexibility and variability of shots taken, as well as the willingness to make risky plays. Methods. The study analyzed the match play of two elite tennis players, Roger Federer and Novak Djokovic, who competed against one another in the final of the 2007 US Open and the semi-final of 2008 Australian Open. Video recording of the two games was used to score and measure the proposed criteria. Results. The study found numerous quantitative and qualitative aspects that could assess the performance of the players. This included measuring the variety, spatial flexibility and variability of shots taken, as well as the willingness to make risky plays. Shot variety, flexibility and variability, as well as the amount of risk taken during game play, were quantifiable in nature. Taking into account the high sporting level of the players, the obtained results are undoubtedly of considerable educational value. Conclusion. The results allow for the conclusion that the teaching process in tennis demands the introduction of significant modifications aimed at the rationalization of technique and the introduction of criteria that can measure player effectiveness.

A new concept is presented for purifying potassium brine (KCl solution) obtained from technical-grade potassium chloride. This concept is based on the hydroxide/carbonate method of removing ions of alkaline earth metals and on separating SO42- ions by means of zirconyl anion exchanger. The purification process provides the following products: purified potassium brine suitable for the manufacture of KClO3 or for further purification and subsequent manufacture of KOH, Cl2 and H2 using membrane cell technology, magnesium and potassium containing agricultural lime (chalk) suitable for neutralizing soil acidity and enriching soil with magnesium and potassium, and technical-grade potassium sulphate containing 99.0 to 99.8% K2SO4.

Oxygen in the human body functions as a transmitter regulating cell bioenergetics and as a substrate in oxidation--reduction reactions, contributing to the formation of highly reactive oxygen species (ROS). The body’s antioxidant defense mechanisms include enzymatic and non-enzymatic systems. Graves’ disease, the underlying cause of which is the autoimmune process, is the most common cause of hyperthyroidism. The most common of the non-thyroid symptoms is orbital tissue inflammation called thyroid orbitopathy (TO). Under physiological conditions, there is a balance between the production of ROS and antioxidant activity. Disruption of this balance may lead to the development of oxidative stress. The article presents a review of the literature on oxidative-reduction processes in TO.

Tlen w organizmie człowieka pełni zarówno funkcję przekaźnika regulującego bioenergetykę komórkową, jak i substratu w reakcjach oksydacyjno-redukcyjnych, przyczyniając się do powstania wysoce reaktywnych form tlenu (RFT). Obronne mechanizmy antyoksydacyjne organizmu obejmują układy enzymatyczny oraz nieenzymatyczny. Choroba Gravesa-Basedowa, której podłożem jest proces autoimmunologiczny, to główna przyczyna nadczynności tarczycy. Najczęstszym z pozatarczycowych objawów jest zapalenie autoimmunologiczne tkanek oczodołu, zwane orbitopatią tarczycową (OT). W warunkach fizjologicznych istnieje równowaga między wytwarzaniem RFT a aktywnością antyoksydacyjną. Zaburzenie tej równowagi może prowadzić do rozwoju stresu oksydacyjnego. W pracy przedstawiono przegląd piśmiennictwa dotyczącego zaburzeń procesów oksydacyjno-redukcyjnych w OT.

Despite development of combustiology, infections continue to be the most important cause of death among patients with burns. Sepsis is the most severe clinical presentation of infection in patients after thermal injuries who require immediate treatment. Early diagnosis and proper treatment of sepsis are important in the clinical management that is often hampered for multiple reasons, e.g. impaired patient immunity, problems with microorganisms with multi-antibacterial drug resistance.The aim of the study was to assess effect of type of a microorganism isolated from blood and wound on results of treatment of sepsis in patients with burns.Material and methods. Effect of type of microorganisms isolated from blood and wound on the result of treatment of sepsis was studied in 338 patients hospitalized immediately after an injury in Centre for Burn Treatment in Siemianowice Śląskie in years 2003 - 2004 (at the age of 18 - 96 years, 66 women and 272 men). Clinical symptoms of generalized infection were found in all study subjects. The study group was divided into two subgroups: cured patients and patients who died of sepsis. The following parameters were assessed in both subgroups: type of microorganism isolated from blood, type of microorganism isolated from wound as well as occurrence of the same and different infections of blood and burn wound.Results. positive blood cultures were found in 165 patients (48.8%), 106 (64.2%) were cured, 59 (35.8%) died. The most commonly isolated microorganisms in cured patients were Gram(+) Staphylococcus epidermidis MRSE (19.81%) and Staphylococcus aureus MRSA (18.87%). Gram(-) intestinal rods were least commonly isolated from this group. The most commonly isolated microorganisms from blood of patients who were to die, included non-fermenting Gram(-) rods Acinetobacter baumannii (35.59%) and Pseudomonas aeruginosa (22.03%). Mixed bacterial flora was found in the blood of 22.03% patients. Among patients who were to die, the same microorganisms were found in the blood and in the wound in 32.2% of patients, while this rate was 17.92 in cured patients. The most commonly found bacteria in the blood and burn wound in the cured patients included Staphylococcus aureus MRSA (31.58%) and Staphylococcus aureus (21.05%). In the group of patients who were to die, the most common bacteria isolated simultaneously from the blood and burn wound included Acinetobacter baumannii (47.37%) and Pseudomonas aeruginosa (36.84%).Conclusions. 1. The patients with thermal injuries are at higher risk of death in the event of sepsis caused by Gram(-) bacteria versus Gram(+) bacteria. 2. Infection of blood and burn wound caused by the same bacteria Pseudomonas aeruginosa and Acinetobacter baumanni increases the risk of death due to sepsis in patients with burns following thermal injuries.

Chronic hepatitis B and C are among the most common liver diseases. A prolonged necroinflammatory process may lead to life-threatening complications although in some cases the liver condition remains stable for many years. Due to its unpredictable prognosis, a great deal of research has been carried out to find additional factors that modify the course of these diseases. Adipocytokines, substances secreted mainly by adipose tissue cells, have become the object of various studies due to their pluripotent impact. This paper aims to present the interrelationship of selected adipo-cytokines and hepatitis B and C, as well as the potential use of this knowledge in medical practice.

Przewlekłe wirusowe zapalenie wątroby (WZW) typu B i C należą do najczęstszych chorób wątroby. Długotrwały proces martwiczo-zapalny może prowadzić do groźnych dla życia powikłań, choć u niektórych pacjentów stan wątroby jest stabilny przez wiele lat. Ze względu na zróżnicowane rokowanie w przebiegu przewlekłego wirusowego zapalenia wątroby (PWZW) typu B i C, poszukuje się obecnie dodatkowych czynników hamujących postęp tych chorób. Obiektem wielu badań stały się adipocytokiny, substancje o wielokierunkowym oddziaływaniu, wytwarzane m.in. przez komórki tkanki tłuszczowej. W pracy przedstawiono wzajemne zależności wybranych adipocytokin i WZW typu B i C oraz potencjalne wykorzystanie tej wiedzy w praktyce lekarskiej.

Inguinal hernia repair and cholecystectomy are amongst the most common surgical procedures performed worldwide. In the recent decades, early disease detection has notably increased due to easily accessible ultrasound. The aim of the study was to assess the safety and the possibility of performing a simultaneous hernia repair and cholecystectomy using the laparoscopic approach. Material and methods. Eight patients (M=100%) with inguinal hernia (3 with bilateral hernia) and cholelithiasis were included in the study. The presence of gallstones was confirmed by imaging. Mean age of the patients was 61.75 years (ranging from 47-72). Simultaneous laparoscopic cholecystectomy and transabdominal pre-peritoneal hernia repair was performed in all patients. Postoperative complications were analyzed to assess the safety and feasibility of the procedure. Results. Mean operating time was 55 minutes (ranging from 30-60) and average length of stay was 3.625 days (ranging from 2-7). In order to perform a cholecystectomy, 1-2 additional trocars were used. No intra-operative complications were observed. At a follow-up visit on postoperative day 7, a small hematoma (10 ml of blood was punctured) in the right groin was noted in one patient. Another patient developed fever postoperatively, treated conservatively with antibiotics. Conclusions. Simultaneous TAPP and cholecystectomy proved to be a safe and feasible procedure. Acceptable operating time and hospital stay, as well as lack of influence on the length of convalescence, may present an interesting alternative to two separate procedures
