Increased rod stiffness improves the degree of deformity correction by segmental pedicle screw fixation in adolescent idiopathic scoliosis.

BACKGROUND: There are limited reports in literature studying the impact of rod diameter and stiffness on the degree of deformity correction in patients with AIS. AIMS: The aims of this study were to evaluate the 3-dimentional deformity correction achieved by segmental pedicle screw fixation in patients with adolescent idiopathic scoliosis, and to find out if learning or the change to stiffer rods

Monitoring of low molecular weight heparin anticoagulation during haemodialysis with a Sonoclot Analyzer.

Objectives: Sonoclot was used in this study to monitor low molecular weight heparin (LMWH) during haemodialysis. Material and Methods: Two different intravenous doses (standard / half-dose) of dalteparin were studied in eight patients. Blood was sampled for coagulation analyses with Sonoclot, thrombin-antithrombin (TAT) and anti-Xa. A visual fibrin deposition score (VFS) in the venous drip chamber

Using the 12-item Short Form health survey (SF-12) to measure quality of life among older people.

AIMS: To present descriptive data, study psychometric abilities, and investigate the characteristics of non-respondents to SF-12. METHOD: The study had a randomized sample (n=4278; age: 75-105) stratified in four age groups. Factor analyses were performed to investigate the factor structure of the instrument, and convergent and discriminant validity was assessed by correlation between summary scor

On the Programming and System Integration of Robots in Flexible Manufacturing

Popular Abstract in Swedish Robotar är maskiner som rör sig efter hur man programmerar dem. I industriellt bruk monteras ofta ett verktyg på roboten så att den kan svetsa, gripa, slipa, borra eller göra andra saker. Det som gör roboten bra på detta är att den kan upprepa robot-programmet flera gånger när det har blivit skrivet. Detta gör att man kan programmera roboten en gång för en arbetsuppgiftAdvanced manufacturing technologies and programmable machines such as industrial robots are used to increase productivity and quality for competitiveness on a global market. Development of increasingly flexible manufacturing systems has resulted in an increasing importance of software aspects, both on a system level and for efficient interaction with human operators. Trends toward providing custom

Clinical measures of islet function: usefulness to characterize defects in diabetes.

In healthy individuals, the ability of the pancreatic islets to sense and respond appropriately to changes in plasma glucose levels maintains plasma glucose levels within a narrow range despite broad fluctuations in nutrient intake and variable "demand" for insulin imposed by changes in insulin sensitivity. This ability of the pancreatic islets is lost in type 2 diabetes (T2DM). For studies on the
