The development of men’s handball was analyzed using data from the Olympic, World and European Championships held within the last eight years. The most obvious change, especially within these last nine tournaments, was that men’s handball was played more dynamically and rapidly, both in attack and defense, especially by European teams. The first aim of this study was to conduct a technical analysis of current handball and to determine factors related to success in this sport discipline. The second aim was to compare the data of European Championships with other tournaments, considering the success of European teams in Men’s World Handball. The technical variables used to compare the tournaments included: the average number of attacks, the efficiency of attacks, the efficiency of goal throws, fast break goals per game, the efficiency of fast breaks, the efficiency of the goalkeeper, saves by the goalkeeper per game, number of turnovers per game, and the efficiency of position throws (wing, pivot, back court, break-through, fast break, and 7-meter). This technical analysis used cumulative statistics from the European Handball Federation and International Handball Federation. ANOVA revealed significant differences between the first eight teams in the European Championships and their counterparts in the other two tournaments (Olympics and World Championships) in terms of several technical variables. The results showed that the efficiency of fast break, pivot position and back court players affected the ranking in favor of the European teams in significant international tournaments.
Denture-induced stomatitis usually occurs in persons who wear a complete or a partial denture. Among the many aetiological and predisposing factors, Candida spp. are believed to play an important role in the initiation and progression of the infection. Seventy cases who attended the clinics of the Dental Faculty, University of Atatürk, Turkey were investigated from the viewpoint of denture-induced stomatitis. After questioning the patients for their personal information, they were examined clinically and smears were obtained from lesions of the palatal mucosa and the contiguous denture surface by calcium aliginate swabs, and inoculated onto Sabouraud dextrose agar supplemented with 1% chloramphenicol, and CHROMagar Candida. Individual yeast species were identified by a germ tube test, development of blastospores, chlamydospores and pseudohyphae and assimilation tests employing the commercial kit API 20C AUX system. According to the results obtained, 70% of the cases had denture-induced stomatitis, and in 68% of them mycological culture results were positive. Candida albicans was the most frequently isolated fungus (68.75%). On the other hand, fungal growth was much more pronounced in the cultures made from the inner surface of the dentures. In conclusion, this study showed that candidal infections are not the predisposing factor in the occurrence of denture-induced stomatitis, but they play a major role, as also some other factors, especially those related with dentures.
Anaemia and oxidative stress are common features of chronic kidney disease, and both are associated with an increase in morbidity and mortality. There is growing evidence, from experimental and clinical studies, that oxidative stress may be implicated in the pathogenesis of anaemia. This study investigated the relationship between total antioxidant capacity, anaemia and serum albumin levels in 127 non-diabetic patients requiring haemodialysis. Total serum antioxidant capacity levels were determined and were found to be significantly correlated with levels of haemoglobin, haematocrit, serum albumin, serum total protein, malondialdehyde (a product of lipid peroxidation), potassium, phosphorus and alanine transaminase. There was also a significant correlation between serum albumin levels and haemoglobin and haematocrit levels. In conclusion, total antioxidant capacity was found to be inversely correlated with malondialdehyde levels and positively correlated with haemoglobin and haematocrit levels in non-diabetic patients requiring haemodialysis. Patients with high serum albumin concentrations and high total antioxidant capacity may also have high (i.e. normal) levels of haemoglobin.
There is growing evidence from experimental and clinical studies that oxidative stress is involved in the pathogenesis of malnutrition. This cross-sectional study aimed to investigate the relationship between glutathione peroxidase (GPx) levels as a marker of antioxidant status and the nutritional status assessed by bioimpedance analysis (BIA). Ninety-seven nondiabetic stable outpatient uremic adults undergoing chronic hemodialysis (HD) were recruited for this study. Impedance measurements were performed using a multifrequency bioelectrical impedance analyzer after dialysis. GPx levels correlated with intracellular water (ICW) (r = 0.341, P = 0.011), ICW/total body weight (r = 0.320, P = 0.017), lean body mass (r = 0.300, P = 0.026) and total body cell mass (r = 0.339, P = 0.011). When patients were divided into two groups according to mean GPx levels (83.9 U/gr hemoglobin), the patients with higher GPx (GPx > 83.9 U/gr hemoglobin) had higher albumin (P = 0.038), lean body mass (P = 0.026), ICW (P = 0.011), and total body cell mass (P = 0.011) compared with those with lower GPx (GPx ≤ 83.9 U/gr hemoglobin). Furthermore, in the patients with higher GPx, body fat; extracellular water/total body water; illness marker and body fat mass index were lower than other group. In conclusion, our results reveal correlation indicating a relationship between antioxidant status (as measured by GPx) and nutritional status as assessed by BIA in nondiabetic HD patients.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
