Type and duration of fetal asphyxial insult affect the distribution of blood flow to the heart and brain. The purpose of this study was to describe dynamic and quantitative changes in regional myocardial and cerebral blood flow (CBF) during fetal asphyxia induced by total occlusion of the umbilical cord. Eleven exteriorized fetal sheep were subjected to total umbilical cord occlusion and five feta

We have recently described frequency-dependent effects of mobile phone microwaves (MWs) of global system for mobile communication (GSM) on human lymphocytes from persons reporting hypersensitivity to electromagnetic fields and healthy persons. Contrary to GSM, universal global telecommunications system (UMTS) mobile phones emit wide-band MW signals. Hypothetically, UMTS MWs may result in higher bi

Back-arc volcanism in the western Argentinian provinces of Mendoza and Neuquen has been widespread from the Miocene to historic times. We present a detailed investigation of profiles through two of the major Miocene volcanic areas of the region, the neighboring Huantraico and La Matancilla plateaus, including new Ar-40/Ar-39 age results of major and trace elements as well as Nd, Sr and Pb isotopic

Genital high-risk human papillomaviruses (HPVs) cause cervical cancer and are also found in a small proportion of nonmelanoma skin cancers (NMSCs). We used cancer registry linkages to follow the 856,000 serum donors included in the Southern Sweden Microbiology Biobank or the Janus Biobank in Norway, for incident skin cancers occurring up to 30 years after serum donation. Serum samples taken before

Abstract Objective. Periodontal ligament (PDL) cells produce IL-6 upon stimulation with inflammation promoters, but the signaling pathways involved have not been characterized. This study investigates underlying mechanisms behind regulation of PDL cell IL-6 production by E. coli and P. gingivalis LPS. Materials and methods: Human PDL cells, endothelial cells and monocytes were stimulated with E. c

We report the discovery of WTS-2 b, an unusually close-in 1.02-d hot Jupiter (M-P = 1.12M(J), R-P = 1.30R(J)) orbiting a K2V star, which has a possible gravitationally bound M-dwarf companion at 0.6 arcsec separation contributing similar to 20 per cent of the total flux in the observed J-band light curve. The planet is only 1.5 times the separation from its host star at which it would be destroyed

Objective: To assess the responsiveness of the Intermittent and Constant Osteoarthritis Pain (ICOAP) measure, Hip Disability and Osteoarthritis Outcome Score Physical Function Short Form (HOOS-PS), and the Knee Disability and Osteoarthritis Outcome Score Physical Function Short Form (KOOS-PS) in a pharmacological trial. Methods: Data were obtained from a randomized double-blind trial comparing nap

BACKGROUND.: Everolimus reduces the progression of cardiac allograft vasculopathy (CAV) in de novo heart transplant (HTx) recipients, but the influence on established CAV is unknown. METHODS.: In this Nordic Certican Trial in Heart and lung Transplantation substudy, 111 maintenance HTx recipients (time post-HTx 5.8±4.3 years) randomized to everolimus+reduced calcineurin inhibitor (CNI) or standard

PURPOSE: To evaluate the plasma level of different forms of soluble urokinase plasminogen activator receptor (suPAR) as discriminators between malignant, borderline, and benign ovarian tumors and as prognostic markers in patients with ovarian cancer. EXPERIMENTAL DESIGN: The different suPAR forms were measured in preoperative plasma samples obtained from 335 patients with adnexal lesions using thr

OBJECTIVE: Treatments have failed to delay or stop the autoimmune process, preceding onset of type 1 diabetes. We investigated if autoantigen-specific treatment with alum-formulated glutamate decarboxylase (GAD-Alum) was safe and affected progression to type 1 diabetes in children with islet autoimmunity.METHODS: In an investigator-initiated, double-blind, placebo-controlled clinical trial, non-di

Background: Individuals with severe alpha-1 antitrypsin deficiency (AATD) have an increased risk of developing COPD. However, outcomes during long-term oxygen therapy (LTOT) in patients with severe AATD and hypoxemia are unknown. Patients and methods: This was a prospective, population-based, consecutive cohort study of patients on LTOT due to COPD in the period from January 1, 1987, to June 30, 2

The objective was to study obesity and insulin resistance in relation to leisure time physical activity (LTPA) and occupational physical activity (OPA) in a Swedish population, with particular focus on sex differences. Using a cross-sectional design, waist circumference, body mass index (BMI), glucose/insulin metabolism, blood pressure, heart rate, self-reported education, smoking, alcohol consump

Aim Despite advances in rectal cancer treatment local recurrence (LR) remains a significant problem. To select high-risk patients for different treatment options aimed at reducing LR, it is essential to identify LR risk factors. Method LR and survival rates of 4157 patients registered 1995-1997 in the Swedish Rectal Cancer Registry were analysed. LR risk factors were analysed by multivariate metho

The fact that breast cancer patients with local or distal dissemination exhibit decreased survival, promotes a search for novel mechanisms to suppress such tumor progression. Here we have determined the expression of pro-inflammatory cysteinyl leukotriene receptors (CysLTRs) in breast tumor tissue and their signaling effect on breast cancer cell functions related to tumor progression. Patients wit

PURPOSEHuman papillomavirus type 16 (HPV16) infection is causing an increasing number of oropharyngeal cancers in the United States and Europe. The aim of our study was to investigate whether HPV antibodies are associated with head and neck cancer risk when measured in prediagnostic sera. METHODSWe identified 638 participants with incident head and neck cancers (patients; 180 oral cancers, 135 oro

BACKGROUND: Current clinical assessments of motor function in Huntington's Disease (HD) rely on subjective ratings such as the Unified Huntington's Disease Rating scale (UHDRS). The ability to track disease progression using simple, objective, inexpensive, and robust measures would be beneficial.METHODS: One objective measure of motor performance is hand-tapping. Over the last 14 years we have rou

Popular Abstract in English Small Devices to Study Small Biology Biological components that are smaller than a cell are difficult to study directly. A great deal of work has been done developing devices and techniques that allow scientists to control and observe sub-cellular biology. In this thesis I, along with my colleagues, have made a number of devices that give us control over the small bioloSub-cellular biological components are complex systems that work together to control and maintain cellular activity and health. It is useful to study the basic elements that constitute the sub-cellular components using model systems, which mimic certain parts of the overall system, in order to better understand the system as a whole. Here we present a number of tools, which enable the study of a f

Languages differ in how events are described, but little is known about how semantics interacts with online event processing. This study targets this question examining placement events in Swedish. Swedish has three obligatory placement verbs for events where objects have support from below: sätta ’set’, ställa ’stand’, and lägga ’lay’. Swedish lacks a superordinate general term like English put (

Slight differences, which appear in the individual animals of the same species and population have been recognised and appreciated ever since Darwin. These consistent intra-specific differences in animals have been considered very important because they are often inherited, and thus, provide the basic material for evolution to act on. This applies also to behavioural characteristics, and thus, to
