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-articul...

osteoarthritis is the most common joint disease.the main pathologic manifestation of disease is local destruction of cartilage in diarthrodial joint. new bone formation in marginal surface of the joint is a sign progressive disease. many systemic and local factors are introduced in initiate and progression of osteoarthritis include: age, sex, weight, race, genetic background, bone densitometry,...

introduction osteochondritis is a joint condition in which bone underneath the cartilage of a joint destroys due to lack of blood flow. then bone and cartilage can break, causing pain and sometimes affecting joint motion and skin around the involved joint might be swollen and tender. osteochondritis occurs most commonly in the knee, but also occurs in elbows, ankles and other joints. decreased ...

BACKGROUND: There is little information about blood supply of the carpal joint in one- humped camel, while there is extensive data about cow and equine species. In order to perform surgeries and diagnostic techniques in carpal region, information about the elements of the joint such as its arteries is necessary. OBJECTIVES: This study aims at describing the origins, arrangements, and branches o...

Abstract Introduction: In this study the role of PGE2 as an important inflammatory mediator in Indomethacine and Theophylline effects on joint diameter and vascular response of chronically inflamed rat knee joint to saphenous nerve stimulation was investigated. Methods: Inflammation was induced by intraarticular injection of 0.2 ml Freund,s Complete Adjuvant (FCA) and 3, 7, 14, 21 days post i...

periodic evaluation and monitoring the health and economic outcome of joint replacement surgery is a common and popular process under the territory of joint registries in many countries. in this article we introduce the methodology used for the foundation of the national iranian joint registry (ijr) with a joint collaboration of the social security organization (sso) and academic research depar...

the kinematics and dynamics of two industrial cooperating robots are presented in this paper. the noc (natural orthogonal complement) method is used to derive the dynamical equations for the motion of two cooperating robots. the joint torques of the two robots are determined based on the optimization techniques in order to obtain unique solution for joint torques. to this end, minimizing the cr...

in this paper standing balance control of a biped with toe-joint is presented. the model consists of an inverted pendulum as the upper body and the foot contains toe-joint. the biped is actuated by two torques at ankle-joint and toe-joint to regulate the upper body in upright position. to model the interaction between foot and the ground, configuration constraints are defined and utilized. to s...

background : joint proprioception plays an important role in limb movement and awareness of position sense. diabetes has a lot of complications such as lossof sensoryfunction, which canleadtoimpaired balance, thus the aim of this study to evaluated joint proprioception and balance in diabetic patients. methods: twenty type ii diabetic patients and20healthy controls participated in this case-con...
