Background: The potential doubling time of a tumor has been suggested to be a measurement of tumor aggressiveness; therefore, it is of interest to find reliable methods to estimate this time. Because of variability in length of the various cell cycle phases, stochastic modeling of the cell cycle might be a suitable approach. Methods: The relative movement curve and the DNA synthesis time were esti

Objective No depression rating scale has yet been designed to identify all clinically important depressive states in elderly. Therefore, this study investigated the Hopkins Symptom Checklist-25 (HSCL-25), a self-rating scale for depression, to see if it was a sensitive indicator of major, minor and subsyndromal depression. Methods Structured interviews of 37 people with a high depressive score and

The antilipolytic effect of insulin on human abdominal subcutaneous adipose tissue and skeletal muscle during local inhibition of cAMP-phosphodiesterases (PDEs) was investigated in vivo, by combining microdialysis with a euglycaemic, hyperinsulinaemic clamp. During hyperinsulinaemia, the glycerol concentration decreased by 40% in fat and by 33% in muscle. Addition of the selective PDE3-inhibitor a

In a laboratory experiment, northern pike Esox lucius gastric evacuation rates did not differ between equal-mass rations of small and large prey. In a comparison between intermediate and large prey, the pike were unable to fit two intermediate prey completely into the stomach at the same time, resulting in two consecutive evacuations, and changes in patterns of gastric evacuation. Thus. total gast

The Strengths and Difficulties Questionnaire (SDQ) has been used among Swedish children since 1996, usually the parent or the teacher version. The self-report version was originally developed for children aged 11-16 years. The aim of this study was to investigate the application of the Swedish self-report version to a representative sample of 1015 senior high school students aged 17-19 years. Girl

Objectives Lymphotoxin beta (LTB) has been found to be upregulated in salivary glands of patients with primary Sjogren's syndrome (pSS). An animal model of pSS also showed ablation of the lymphoid organisation and a marked improvement in salivary gland function on blocking the LTB receptor pathway. This study aimed to investigate whether single-nucleotide polymorphisms (SNP) in the lymphotoxin alp

The effect of body size on spatial resource competition and reproductive isolation was examined in a sister species pair of subtidal triplefin fishes (F. Tripterygiidae) in New Zealand. Ruanoho decemdigitatus and Ruanoho whero have overlapping sympatric distributions and differ in body size, attaining a total length of 12 cm and 9 cm, respectively. R. decemdigitatus was most commonly found in shel

Objective/Background: Reports on heart failure (HF) predictors are scarce. We assessed gender-specific HF predictors. Design: Preventive case-finding programme, register study. Setting: City population-based sample. Methods: We examined 33,342 HF-free subjects, 32.7% women, included in Malmo Preventive Project. Mean inclusion age was 49.7±7.4 years for women and 43.7±6.6 years for men. Results

The low-lying structures of the self-conjugate (N = Z) nuclei Nb-82(41)41 and Tc-86(43)43 have been investigated using isomeric-decay spectroscopy following the projectile fragmentation of a Ag-107 beam. These represent the heaviest odd-odd N = Z nuclei in which internal decays have been identified to date. The resulting level schemes shed light on the shape evolution along the N = Z line between

Background: To assess balance in single-limb stance, center of pressure movements can be registered by stabilometry with force platforms. This can be used for evaluation of injuries to the lower extremities. It is important to ensure that the assessment tools we use in the clinical setting and in research have minimal measurement error. Previous studies have shown that the ability to maintain stan

The Swedish Joint Facilities create a common resource system for externalities of the individual property, such as common roads, bridges, residential services (waste disposal, car park, community places), irrigation and drainage schemes, and hunting ground. In a historical perspective, such facilities belonged to the village community, and remained as externalities when the society forced an inter

The aim of this study has been to identify, explain and delineate praying among peasant communities in the ecclesiastical province of Uppsala, Sweden. Four aspects have been examined through the perspectives of ideals and practices, namely the standards of prayer, devotional prayer, prayer in times of need and prayer cultures. The standards of prayer considered the physical and mental behaviour of

The purpose of this thesis is to characterize the health status of the population in early Lund. This is pursued by an osteological analysis of 3.305 individuals fron three time periods: c. 990-1100, c. 1100-1300 and c. 1300-1536. The individuals derives from cemeteries connected to four neighbouring churches, where one is the sucessor of the other (Trinitatis). One cemetery (Kattesund) is by and

Proton Exchange Membrane (PEM) fuel cell systems have been studied as the alternatives of the internal combustion engine systems. However, these systems are not appearing in daily life yet, due to the high cost, shortage of infrastructure, technical issues, etc. Concerning technical issues, water/thermal management is a critical one to keep high proton conductivity in the electrolyte membrane for
