We investigate radiation-imprisonment (RI) phenomena in a system of cold atoms trapped in magneto-optical traps (MOTs) when cooling lasers are switched off for a short period. The problem is formulated within the framework of the Streater-Cooper-Sandle equation that belongs to the Markov class and accounts for photon frequency redistribution in multiple scattering processes. On the basis of a semi
Background: Continuous ligand depletion of endocrine responsive tumours may enhance resistance to therapy. Intermittent treatment with tamoxifen (T) was considered to mimic (incomplete) ligand depletion and reintroduction. Furthermore it was postulated that alternating tamoxifen with a non-cross resistant endocrine modality could (further) postpone hormone resistance. Patients and methods: Postmen
DNA fragments containing mispaired and modified bases, bulges, lesions and specific sequences have altered conformation. Methods for separating complex samples of DNA fragments based on conformation but independent of length have many applications, including (i) separation of mismatched or unmatched DNA fragments from those perfectly matched; (ii) simultaneous, diagnostic, mismatch scanning of mul
Ninety-six south Swedish taxa in Hieracium L. sect. Hieracium and H. sect Vulgata (Griseb.) Willk. & Lange are lectotypified. The authorship of each name is analysed and the identity and synonomy of some dubious taxa are discussed. - Flora Nordica Note no. 24.
P>Basal metabolic rate (BMR) is an important trait in the study of energy management of an individual, especially in small wintering passerines from the north which have one of the highest energy turnover rates in vertebrates. Laboratory studies have shown the trait to be repeatable and heritable, despite its plastic nature. However there is currently a lack of empirical data from wild passerine p
Objectives. The EGFR is expressed in malignant ovarian tumor tissue, and tissue content of EGFR has been directly associated with poor prognosis in patients with ovarian cancer. The uPA system plays a role in pericellular proteolysis, cell migration, invasion, and is over-expressed in ovarian cancer. This study explored the effects of EGF on uPAR expression in the ovarian cancer cell line OVCAR-3.
Purpose: Lymph node status is one of the most important prognostic factors in muscle-invasive bladder cancer. The extent of lymphadenectomy performed in conjunction with cystectomy and the question as to whether this is a staging or therapeutic intervention are matters of discussion. The aim of this study was to evaluate the sentinel node (SN) concept and to correlate findings with tumour status i
The objectives of this study are to develop and demonstrate an approach to improve emergency response capability by strengthening individual and organisational learning from the evaluations of specific emergency responses. An approach was developed based on theories of individual and organisational learning. It was applied to evaluations of three instances of emergency response in the city of Malm
Purpose: The goal of this research was to evaluate a potential therapeutic agent for breast cancer based on galectin-3 that has been implicated in tumorigenicity and metastasis of breast cancer. The hypothesis was that therapy with NH2-terminally truncated form of galectin-3 (galectin-3C) will be efficacious for reduction in tumor growth and for inhibition of metastases. Experimental Design: Recom
Coalitions will probably become an increasingly important theme in European Union (EU) politics. The spread of decision making by majority voting promotes coalition-building behaviour. The impending enlargement is predicted to differentiate and polarize policy standpoints within the EU. Increasing levels of policy conflict imply increased propensities for coalition building. Still, the role and na
The present work investigates the occurrence and significance of aberrant DNA methylation patterns during early stages of atherosclerosis. To this end, we asked whether the genetically atherosclerosis-prone APOEnull mice show any changes in DNA methylation patterns before the appearance of histologically detectable vascular lesion. We exploited a combination of various techniques: DNA fingerprinti
Stigma has been identified as one of the most important obstacles for a successful integration of people with mental illness into the society. Research about stigma has shown negative attitudes among the public towards people with mental illness. Studies so far have, however, put little emphasis on how these negative attitudes are perceived by the mentally ill persons. The aim of the present study
Objective. Time to theoretical indication of joint replacement surgery has been proposed as a primary outcome for potential structure-modifying interventions for osteoarthritis (OA). The objectives of this OMERACT/OARSI Working Group were to identify pain, physical function, and structure states that represent the progression from early to late disease for individuals with OA of the hip and knee,
The issue of factors predisposing for inhibitor development in haemophilia patients is still largely unresolved. In an attempt to address this problem, we initiated a registry in 1996 of siblings with haemophilia and with or without a history of inhibitors. Four hundred and sixty families have accrued, of whom 388 suffer from haemophilia A and 72 haemophilia B. Twenty-five of the brother pairs are
Background: Surgical trauma evokes a systemic cytokine response which is enhanced in patients with colorectal cancer. The aim of this study was to locate the origin of the systemic cytokine response to colorectal surgery. Methods: The concentrations of interleukin-6 (IL-6) and tumour necrosis factor-alpha (TNF-alpha) were analysed in systemic and mesenteric venous blood in 12 patients operated on
Two ecotypes of a marine intertidal snail (Littorina saxatilis), living at different microhabitats and shore levels, have evolved in sympatry and in parallel across the Galician rocky shore. These ecotypes differ in many traits (including size) due to differential adaptation. They meet, mate assortatively, and partially hybridize at the mid shore where the two microhabitats overlap. The partial se
The aetiology of benign prostatic hyperplasia (BPH) remains unclear. The objective of the present study was to test the insulin, oestradiol and metabolic syndrome hypotheses as promoters of BPH. The design was a risk factor analysis of BPH in which the total prostate gland volume was related to endocrine and anthropometric factors. The participants studied were 184 representative men, aged 72-76 y
Soot formation in a turbulent jet diffusion flame is modeled using an unsteady flamelet approach in post-process. In the present work, we apply a detailed kinetic soot model with a sectional method, and study the evolution of the particle size distribution. Detailed information on the evolution of the soot particle size distribution function is acquired. It is found that the particle size distribu
