The deleterious effects of inbreeding can be substantial in wild populations and mechanisms to avoid such matings have evolved in many organisms. In situations where social mate choice is restricted, extrapair paternity may be a strategy used by females to avoid inbreeding and increase offspring heterozygosity. In the cooperatively breeding Seychelles warbler, Acrocephalus sechellensis, neither so

Haemophilia is a rare and potentially life-threatening disease. In Sweden, with a population of approximately 8.5 million, about 350 people suffer from the more severe forms of haemophilia or von Willebrand disease. Meticulous management is important if the patients are to be spared chronic disability and serious treatment complications. The disease is lifelong and affects psychosocial aspects of

In arterial vessel wall characterisation the longitudinal movements of vessels have gained little or no attention. It has been presumed that the arterial vessels move very little in the longitudinal direction. With modern high resolution ultrasound it can, however, be seen that arterial vessels move not only in the circumferential, but also in longitudinal direction. This paper describes a non-inv

The level scheme of Mn-51 has been investigated using the Si-28(S-32 2alpha1p)Mn-51 fusion-evaporation reaction at 125 MeV beam energy. The gamma rays were detected in the Ge-detector array Gammasphere, which was coupled to the 4pi-charged-particle detector Microball and the Neutron Shell for the coincident detection of evaporated particles. Over 100 new gamma-ray transitions connecting some 50 ex

1. The effects of antimalarial drugs on the intracellular signaling leading to activation of the phospholipase C and phospholipase A2 pathways and the induction of proinflammatory cytokines have been studied in mouse macrophages. 2. Both chloroquine and quinacrine, and to a lesser extent hydroxychloroquine, inhibited arachidonate release and eicosanoid formation induced by phorbol diester. This in

Objectives & Methods: Diseases of the human urinary tract represent common morbidities characterized by a high prevalence in the population of most westernized countries. The existeince of a significant number of affected patients and the recent increase in scientific attention has resulted in various experimental and clinical efforts in order to evaluate the mechanisms controlling the functio

Knockout of caspase-8, a cysteine protease that participates in the signaling for cell death by receptors of the TNF/nerve growth factor family, is lethal to mice in utero. To explore tissue-specific roles of this enzyme, we established its conditional knockout using the Cre/loxP recombination system. Consistent with its role in cell death induction, deletion of caspase-8 in hepatocytes protected

One purpose of the present study is to explore the stability of the pattern of health/work and sickness absence among middle-aged women over a period of three years. This study tested two hypotheses: (a) that enduringly healthy working women would perceive more valued occupational roles and higher well-being than long-term sick-listed women; (b) that high levels of well-being at baseline would pre

Purpose: To examine whether panretinal photocoagulation for severe non-proliferative retinopathy in type 1 diabetes patients could halt the progression of retinopathy with subsequent vitreous haemorrhages and visual impairment. Methods: During a 10-year follow-up study period of 344 type 1 diabetes patients, 81 subjects went through panretinal photocoagulation. Forty patients were treated for sev

Att golvbeläggningar som läggs på betong som inte fått torka ut ordentligt kan skadas är känt sedan länge. Under senare år har även avgivningen av luktande kemiska ämnen från golvsystem studerats närmare. Eftersom risken för skador ökar när betongunderlaget är fuktigt har det blivit allt vanligare att man ökar betongkvaliteten för att förkorta torktiden. Det har visat sig att nedbrytningen av lim

The near-infrared electronic spectrum of AuO1 has been re-examined in light of the new microwave data on the nu = 0 and nu = 1 vibrations of the X-2 Pi(3/2) state of AuO. The two observed bands in the spectrum, with red-degraded bandheads located at 10726 and 10665 cm(-1), have been reanalyzed. New theoretical work on AuO clarifies the electronic structure, and the bands in the infrared are now as

The study aimed to estimate the relative dose potency of salbutamol inhaled via Turbuhaler and Diskhaler. The 24 adult patients participating had chronic reversible airway obstruction. The study was of a double-blind, double-dummy, crossover, randomized design. Five doses of salbutamol Turbuhaler, 50, 50, 100, 200, and 400 microg, were given on one study day at intervals of 30 min. On another stud
