The present work is mainly focused on the development of enzyme-based bioanalytical devices, which can further be applied as analytical tools for industrial, medical and environmental applications. The first part of the work deals with the practical applications of thermometric biosensors for determination of various sugars (fructose and lactose) in a real samples. Thermometric biosensors possess

When developing products, engineering designers often face the problem that their candidate for a technical solution, ranging from a concept to a detailed design, needs to be analyzed by a design analyst before it is approved or rejected and the engineering designer can continue his/her activities within the product development process. If engineering designers have to send every solution candidat

Mechanical load through physical activity has been shown to be one of the best stimuli to increase the bone strength. This effect of mechanical load accounts for both the accrual of bone mineral and structural skeletal adaptations. Exercise prescription also includes a "window of opportunity" in the late pre- and early peri-pubertal period, where exercise is supposed to insert the most obvious ben

Inflammation is a well-established risk factor for the development of coronary artery disease (CAD) and acute coronary syndrome (ACS). However, less is known about its influence on the outcome of ACS. The aim of this study was to determine if blood biomarkers of inflammation were associated specifically with acute myocardial infarction (MI) or unstable angina (UA) in patients with ACS.

Falls and fractures share several common risk factors. Although past falls is not included as an input variable in the FRAX calculator, we demonstrate that FRAX probability predicts risk of incident falls in the MrOs Sweden cohort.

ABSTRACT: BACKGROUND: Hip dislocation after arthroplasty for femoral neck fractures remains a serious complication. The aim of our study was to investigate the dislocation rate in acute femoral neck fracture patients operated with a posterior approach with cemented conventional or dual articulation acetabular components. METHODS: We compared the dislocation rate in 56 consecutive patients operated

Context: The age-related decline in dehydroepiandrosterone (DHEA) levels is thought to be of importance for general and vascular aging. However, data on the association between DHEA and mortality are conflicting. Objectives: We tested the hypothesis that low serum DHEA and DHEA sulfate (DHEA-S) levels predict all-cause and cardiovascular disease (CVD) death in elderly men. Design, Setting, and Par

To determine if primary hand osteoarthritis (OA) is associated with abnormal bone and anthropometric traits.

Abstract Data from arthroplasty registers are often analyzed using survival methods. Several methodological problems exist, for example relating to competing events, non-random censoring, non-proportional hazards and dependent observations. League tables and ranking of specific survival results leds to further methodological difficulties. Most of these problems are, however, well known and a numbe

Aim: To present gender-specific normative data on estimates of neuromuscular performance, such as muscle strength, vertical jump and standing unilateral balance, in pre-pubertal children. Methods: Lean body mass (kg) and fat mass (%) were estimated by dual-energy X-ray absorptiometry in 246 boys and 190 girls aged 6-12 years in Tanner stages 1 and 2. Isokinetic concentric peak torque at 60 and 180

Background and purpose Hemiarthroplasty as treatment for femoral neck fractures has increased markedly in Sweden during the last decade. In this prospective observational study, we wanted to identify risk factors for reoperation in modular hemiarthroplasties and to evaluate mortality in this patient group. Patients and methods We assessed 23,509 procedures from the Swedish Hip Arthroplasty Registe

The aim of this study was to identify factors associated with repeated suicide attempts among criminal justice clients examined for substance abuse using the Addiction Severity Index. Among suicide attempters (n = 1,404), repeaters (two or more attempts, n = 770) were compared to nonrepeaters. In logistic regression, repetition was associated with younger age, opioid analgesics, somatic medication
