Histamine is synthetized in the heart, and released by ischemia-reperfusion injury in several species. Histamine has arrhythmogenic, chronotropic, inotropic and vasoactive effects. Cardiac histamine release during ischemia-reperfusion may be mediated by toxic oxygen metabolites. We studied the effect of ischemia-reperfusion and toxic oxygen metabolites on(More)
The beneficial effects of probiotic Enterococcus spp. in different hosts, such as mice and humans, have previously been reported in several studies. However, studies of large domestic animals, as well as challenge studies with pathogenic microorganisms, are very rare. Here, we investigated the influence of oral treatment of pigs with the probiotic bacterium(More)
The analysis of network traffic can provide important information for network operators and administrators. One of the main purposes of traffic analysis is to identify the traffic mixture the network carries. A couple of different approaches have been proposed in the literature, but none of them performs well for all different application traffic types(More)
The purpose of this study is to evaluate the objective, subjective, and radiographic results of arthroscopic biceps tenotomy in selected patients with rotator cuff tears. Three hundred seven arthroscopic biceps tenotomies were performed in patients with full- thickness rotator cuff tears. Patients were selected for arthroscopic tenotomy if the tear was(More)
Phylogenetic relationships and genetic variation were examined in the genus Solanum based on the random amplified polymorphic DNA (RAPD) technique. Genetic distances were estimated for 42 accessions from five subgenera [Archaesolanum, Minon (Syn. Brevantherum), Leptostemonum, Potatoe, and Solanum]. This investigation provided new information and reinforced(More)
Although the direct inhibitory effect of small dose of capsaicin on gastric secretory responses was proved in animal observations, the role of capsaicin-sensitive afferent nerves (CSAN) and the effect of capsaicin applied in small and high doses on gastric secretion in human has not been clarified yet. In this study we investigated the influence of(More)
The aim of these experiments was to investigate the expression of cyclin D1 and of oestradiol receptors as well as the level of [(3)H]oestradiol binding in leiomyoma and adjacent myometrium from human uteri at different menstrual phases and at an early stage of menopause. [(3)H]oestradiol binding was determined by saturation analysis, while the oestradiol(More)
The hose resource provisioning model promises to provide an easy–to–use characterization framework for Virtual Private Network service offerings. Significant research effort has recently been spent on proposing new algorithms for provisioning cost–optimal networks specified according to this new model. However, a detailed comparison of the bandwidth(More)
BACKGROUND Rotator cuff tears involving the subscapularis are less common than those involving the superior aspect of the rotator cuff. The purpose of the present study was to report the results of repair of isolated tears of the subscapularis. METHODS The records on eighty-four shoulders that had undergone open repair of the subscapularis tendon were(More)
OBJECTIVE The expression of claudins, the main tight junction proteins involved in cell adhesion and carcinogenesis, was studied in endometrioid (type I) and seropapillary (type II) endometrial adenocarcinoma. The characteristics and possible diagnostic potential of claudin expression pattern were investigated in the two cancer types having different(More)
