Background: Interleukin-8 (IL-8) is an angiogenic chemokine that plays a potent role in both development and progression of many human malignancies. Patients and methods: A hospital-based case-control study was conducted among 109 patients with osteosarcoma and 109 healthy controls to investigate the possible association between the IL-8 rs4073 polymorphisms and the risk of osteosarcoma. Result...

The main challenge of immunosuppressive therapy after solid organ transplantation is to create a new immunological balance that prevents rejection and does not promote opportunistic infection. Torque teno virus (TTV), ubiquitous non-pathogenic single-stranded DNA virus, has been proposed as marker functional immunity in immunocompromised patients. Here we investigate whether TTV loads predict t...

OBJECTIVE Torque teno virus (TTV) infects patients at risk for parenteral exposure and chronic blood transfusion, such as those with β-thalassemic. This study aimed to assess the prevalence of TTV infection and co-infection of TTV and hepatitis C virus (HCV) in pediatric thalassemia patients receiving chronic blood transfusion. MATERIAL AND METHODS The study included 90 pediatric thalassemia ...

PURPOSE Crank torque (CT) application and rate of CT development (RCTD) are important considerations in sprint cycling. The stiffness of the musculotendinous unit is related to the isometric rate of torque development (RTD); however, this relationship has yet to be examined in sprint cycling. METHODS Maximal isometric torque (MIT) and isometric RTD of the quadriceps were assessed in 21 traine...

Since a Japanese-style bow has a very complicated shape and structure, an archer has to apply the "Teno-uchi" maneuver including horizontally twisting torque, or "Nejiri", and sagittally down-pushing torque, or "Uwa-oshi", to the restoring bow in order to hit the target. The purpose of this study was to investigate the biomechanical relationship between the muscular activities of the left forea...
