This paper presents exact joint confidence regions for the parameters of the Rayleigh distribution based on record data. By providing some appropriate pivotal quantities, we construct several joint confidence regions for the Rayleigh parameters. These joint confidence regions are useful for constructing confidence regions for functions of the unknown parameters. Applications of the joint confid...

Background & Aims: Acute acromioclavicular (AC) joint dislocation is common in shoulder injuries. Considering the biomechanics of this joint, the use of a treatment method, which can restore joint physiology and biomechanics to the extent possible, is important. This study aimed to compare the treatment of acute AC joint dislocation by screw fixation with and without ligament reconstruction. Me...

osteochondritis dissecans (ocd) is a common joint disorder in knee, ankle and elbow, however it can be rarely found in glenohumeral joint. in this study, we report an asymptomatic case of humeral head ocd, which was detected incidentally following a trauma. x-rays showed an area of lucency around an oval bony fragment measuring about 1 cm on the superior aspect of the humeral head. however, the...

background appropriate treatment of acromioclavicular joint dislocation is controversial. acroplate fixation is one of the most common treatment methods of acromioclavicular joint (acj) dislocation. based on the risk of re-dislocation after acroplate fixation, we assumed that combined fixation with an acroplate and a coracoclavicular screw helps improve the outcome. objectives the main purpose ...

introduction: there are differences in the pattern of the knee joint formation of the studied species. according to the small number of studies which focused chronologically on the avian knee histomorphogenetic events, its “morphogenetic pattern” is hard to be proposed. the present work was designed to identify the sequential events of the knee formation in the partridge embryo. regarding to di...

previous in vitro work on rabbit knee joint vessels showed that vasoconstrictor effects of nerve stimulation and administration of α-adrenoceptor agonists were mediated predominantly by α1-adrenoceptors5,9 the present experiments were performed to assess the nature of α-adrenoceptor subtypes within these blood vessels in vivo. dose/response relationships for adrenaline and noradrenaline produce...

Background: Angiotensin converting enzyme (ACE) upregulation in stromal cells of joints affected by rheumatoid arthritis may lead to higher tissue angiotensin II that is a vasoconstrictor and mitogen factor. To date, the role of angiotensin II on regulating blood flow in inflamed joints has not been studied. Methods: Acute and chronic joint inflammation was induced in rabbits by intra-articular...

joint pain is one of the most common complaints with many possible causes.some medicines used for joint pain relief such as nsaids have substantial and frequent side effects. topical route possibly reduces adverse reactions by maximizing local delivery and minimizing systemic toxicity. throughout history, plants have been the most important sources of medicines for human health and iranian trad...
