The Black-headed Gull Larus ridibundus is a monomorphic species with little size variation over its wide distribution range. This is in agreement with the wide dispersal of young birds and change of breeding sites of adults between years, which probably means an almost panmictic dispersal of genes. In 1965 I measured and weighed 319 eggs collected at Sjolunda near Malmo, southern Sweden. When I go

Study Design. Observational cohort study. Objective. To evaluate by MRI whether a vertebral fracture during childhood is a risk factor for degeneration of adjacent discs. Summary of Background Data. Several studies infer that trauma is a major cause of disc degeneration. Only 1 study has by magnetic resonance imaging (MRI) evaluated disc degeneration in children with a former thoracic or lumbar ve

Serine protease inhibitors (Serpins) are involved in the pathogenesis of neurodegenerative dementia, including the two most common types, Alzheimer’s disease (AD) and dementia with Lewy bodies (DLB). The pathological characteristics of AD include senile plaques, mainly composed of aggregated amyloid-beta peptide (Abeta1-42), but also serpins, and neurofibrillary tangles of hyperphosphorylated tau

This short essay on how the book is used in Dutch paintings of the 16th and 17th centuries stresses the ambiguities of its overt message and latent symbolism, more varied than mere erudition or inevitable mortality.

Giant cell reparative granuloma (GCRG) is an uncommon lesion most often affecting the jaw but also the small bones of the hands and feet. GCRG overlaps clinically and radiographically with other giant cell-rich tumors such as giant cell tumor of bone (GCTB) and aneurysmal bone cyst (ABC). In the only case of a cytogenetically investigated GCRG reported previously, a balanced translocation involvin

Flertalet nya läkemedel tas fram av universitet och undervisningssjukhus, ofta med betydande offentliga subsidier, för att därefter tas över av läkemedelsindustrin, vars främsta uppgift är att utföra de kliniska prövningarna. Det är viktigt nog, men betydligt mindre innovativt än vad industrin vill få oss att tro, skriver Anders Jeppsson i polemik mot ett tidigare inlägg av Pierre Lafolie.

The difference in length of breast feeding between women with a BRCA 1 mutation and their unaffected relatives was investigated. Fifty women belonging to a family with a known BRCA1 mutation had themselves undergone testing and each had given birth to at least one child. Women with BRCA1 mutation breast-fed their first infant for a significantly shorter period (P = 0.048) and the second and third

Introduction: We investigated whether there were any differences in the frequency and severity of pin site infections by performing pin site care daily or once a week. We studied patients operated on for gonarthrosis by the hemicallotasis technique, using hydroxyapatite-coated pins in the metaphyseal bone and standard pins in the diaphyseal bone. Patients and methods: 50 patients were prospectivel

Spatially and spectrally resolved cathodoluminescence in the scanning electron microscope is a very powerful technique for studying the optical properties of semiconductor structures, especially low-dimensional structures (structures with nanometre-sized features). The technique is generally nondestructive and can be combined with the normal imaging capabilities and analysis possibilities of the s

Objective.. To describe the diversity in dietary patterns existing across centres/regions participating in the European Prospective Investigation into Cancer and Nutrition (EPIC). Design and setting.. Single 24-hour dietary recall measurements were obtained by means of standardised face-to-face interviews using the EPIC-SOFT software. These have been used to present a graphic multi-dimensional com

Aims: Objectives were (a) to estimate healthcare cost and productivity losses due to smoking in Sweden 2001 and (b) to compare the results with studies for Sweden 1980, Canada 1991, Germany 1996, and the USA 1998. Methods: Published estimates on relative risks and Swedish smoking patterns were used to calculate attributable risks for smokers and former smokers. These were applied to cost estimates

The purpose of the present study was to develop a new model of the initial part of an evacuation process, i.e., the pre-movement phase. A new method for estimating the pre-movement time was also going to be proposed. In the initial part of the study an inventory of existing models of human behaviour during fire evacuation was performed. This was followed by a literature review about helping behavi
