In pulse-echo (PE) ultrasound measurements, the use of focused transducers is desirable for quantitative assessment of bone characteristics because of the attenuation in the overlying soft tissues. However, the variable thickness and composition of the soft tissue overlying bone affect the focal depth of the ultrasound beam and induce errors into the measurements. To compensate for the attenuation
The chromosome number of human tumors varies widely, from near-haploidy to more than decaploidy. Overt hyperhaploid (24-34 chromosomes) tumors constitute a small minority (0.2-0.3% of cytogenetically investigated lesions), but occur in many different disease entities. In these karyotypes, most chromosomes are present in one copy; one or a few chromosomes are disomic. Published reports on 141 stric
Background and Purpose. In clinical practice, visual observation is often used to determine functional impairment and to evaluate treatment following a knee injury. The aim of this study was to evaluate the reliability and validity of observational assessments of knee movement pattern quality during five functional tests in subjects with an anterior cruciate ligament (ACL) injury. Method. Twelve A
In April 2010, young students from 21 countries competed in EUSO - the European Union Science Olympiad. Each country sent two teams of three students to an experimental science competition. The first day, the teams helped an alien find water on Earth, and the second day, they solved a criminal case.
The oncogene cyclin D1 is highly expressed in many breast cancers and, despite its proliferation-activating properties, it has been linked to a less malignant phenotype. To clarify this observation, we focused on two key components of malignant behavior, migration and proliferation, and observed that quiescent G0/G1 cells display an increased migratory capacity compared to cycling cells. We also f
Neutrophil infiltration is an insidious feature in septic lung injury, although the specific adhesive mechanisms regulating pulmonary recruitment of neutrophils in polymicrobial sepsis remain elusive. The aim of this present study was to define the role of CD44 in sepsis-induced neutrophil infiltration and lung damage. Mice were treated with a monoclonal antibody against CD44 before cecal ligation
Introduction: The concentration of carboxypeptidase B activation peptide (CAPAP) is proposed to be a predictor of severe acute pancreatitis. The activated protein C (APC)-protein C inhibitor (PCI; APC-PCI) complex in plasma could be useful in detecting the hypercoagulative condition in severe acute pancreatitis. Method: In this prospective study, mild (n = 50) and severe (n = 9) cases of acute pan
Every 30 s, a lower limb is amputated due to diabetes. Of all amputations in diabetic patients 85% are preceded by a foot ulcer which subsequently deteriorates to a severe infection or gangrene. There is a complexity of factors related to healing of foot ulcers including strategies for treatment of decreased perfusion, oedema, pain, infection, metabolic disturbances, malnutrition, non-weight beari
The hypotheses were based on conceiving of automatic mimicking as involved in emotio¬nal empathy. Mimicry reactions (EMG) in high- and low-empathy subjects were studied when subjects were exposed to pictures of angry or happy faces. The degree of corre¬sponden¬ce between subjects’ facial EMG reactions and their self-reported feelings was compared. The comparisons were made at different stimulus ex
Our aims were to investigate possible associations between hospitalisation for venous thromboembolism (VTE) and socioeconomic and occupational factors. A nationwide database was constructed by linking Swedish census data to the Hospital Discharge Register (1990-2007). Hospital diagnoses of VTE were based on the International Classification of Diseases. Standardised incidence ratios were calculated
We examined associations between food intakes and incident breast cancer, defined by estrogen receptor (ER) and progesterone receptor (PR) status in the Malmö Diet and Cancer cohort (17,000 women aged 45-73 yr). The hazard ratios (HRs) of ER+PR+ (n = 270), ER+PR- (n = 87), and ER-PR- (n = 61) tumors and all cancer (n = 544) were estimated after 10 yr of follow-up. In multivariate analysis of ER+PR
Combinatorial libraries and selection of variants from such libraries have proven to be a successful approach for identifying molecules with novel or improved properties. The importance of antibody (Ab) molecules in basic and applied research, as well as the extensive knowledge of how they interact with their antigen (Ag) targets, have made them favorite targets for modification by this approach.
This article demonstrates how a dominant and an alternative interpretative repertoire are activated and negotiated within two focus group discussions conducted with elderly people around the issue of fear of crime: the active, competent actor and the potential victim. In contrast to quantitative generalist studies that tend to neglect the ambiguity and complexity of group membership and identifica
One of the most common practical inventory control problems is considered. A single-echelon inventory system is controlled by a continuous review (R,Q) policy. The lead-time demand is normally distributed. We wish to minimize holding and ordering costs under a fill rate constraint. Although, it is not especially complicated to derive the optimal solution, it is much more common in practice to use
Results of reliability studies on physical performance tests are often conflicting. The main purpose of this study was to analyse the inter-rater reliability and between-days repeatability of physical performance tests on a female working population. Twenty-two nursing aides/ assistant nurses were tested twice, with, on average, a 5-day interval. Seventeen of these were tested again, after an aver
