STUDIES OF EFFECTS OF GSM-900 MICROWAVE EXPOSURE ON DNA ”MICRONUCLEUS” FORMATION IN MICE

Possible genotoxic effects of microwave exposure from GSM-900 mobile telephones have investigated with in vivo micronucleus assay of mouse erythrocytes from CBA mice and GFAP knockout mice. No significant change in the frequency of erythrocytes with micronuclei neither in the young (polychromatic PCE) or mature (normichromatic NCE) erythrocytes. There is, however, a tendency but not significant to

A model of significant wave height for reliability assessment of a ship

Significant wave heights are modeled by means of a spatial-temporal random Gaussian field. Its dependent structure can be localized by introduction of time and space dependent parameters in the spectrum. The model has the advantage of having a relatively small number of parameters. These parameters have natural physical interpretation and are statistically fitted to represent variability of observ

Infrared Spectra and Quantum Chemical Calculations of the Uranium Carbide Molecules UC and CUC with Triple Bonds.

Laser evaporation of carbon-rich uranium/carbon alloys followed by atom reactions in a solid argon matrix and trapping at 8 K gives weak infrared absorptions for CUO at 852 and 804 cm−1. A new band at 827 cm−1 becomes a doublet with mixed carbon 12 and 13 isotopes and exhibits the 1.0381 isotopic frequency ratio, which is appropriate for the UC diatomic molecule, and another new band at 891 cm−1 g

Phylogeography and conservation genetics of the common wall lizard, Podarcis muralis, on islands at its northern range.

Populations at range limits are often characterized by lower genetic diversity, increased genetic isolation and differentiation relative to populations at the core of geographical ranges. Furthermore, it is increasingly recognized that populations situated at range limits might be the result of human introductions rather than natural dispersal. It is therefore important to document the origin and

Sociala normer och regelefterlevnad : Trafiksäkerhetsfrågor ur ett rättssociologiskt perspektiv

The thesis aims to: (a) broaden the knowledge base that makes up the foundation for decisions with regard to how traffic law enforcement is best outlined, as well as increasing the understanding of how the shaping of different public instruments of control affects the chances of success; and (b) contribute to the development of theory and methodology within sociology of law. The relationship betwe

Development and Validation of a Risk Score Predicting Substantial Weight Gain over 5 Years in Middle-Aged European Men and Women

Background: Identifying individuals at high risk of excess weight gain may help targeting prevention efforts at those at risk of various metabolic diseases associated with weight gain. Our aim was to develop a risk score to identify these individuals and validate it in an external population. Methods: We used lifestyle and nutritional data from 53 degrees 758 individuals followed for a median of 5

MAPK and pro-inflammatory mediators in the walls of brain blood vessels following cerebral ischemia

INTRODUCTION Stroke is a serious neurological disease which may lead to death and severe disability [1, 2]. There are two major types of stroke: ischemic and hemorrhagic stroke. Both are associated with disruption of blood flow to a part of the brain with rapid depletion of cellular energy and oxygen, resulting in ionic disturbances and eventually neuronal cell death [3]. The pathologic process t

Offspring size and timing of hatching determine survival and reproductive output in a lizard

Selection on offspring size and timing of birth or hatching could have important consequences for maternal investment strategies. Here we show consistent viability selection on hatchling body length across 2 consecutive years in a lizard that lays several clutches per season. There was no effect of hatching date on survival to maturity. However, both early hatching and large hatchling size increas

What makes entrepreneurship research interesting? Reflections on strategies to overcome the rigour-relevance gap

As entrepreneurship researchers compete to have their work published and universities strive to attract the best entrepreneurship scholars, it is appropriate to examine what makes entrepreneurship research interesting. Interesting studies are usually defined as well-crafted and well-written studies that challenge established knowledge, and produce new theories and findings. This paper examines ent

Hypothesis-Based Analysis of Gene-Gene Interactions and Risk of Myocardial Infarction

The genetic loci that have been found by genome-wide association studies to modulate risk of coronary heart disease explain only a fraction of its total variance, and gene-gene interactions have been proposed as a potential source of the remaining heritability. Given the potentially large testing burden, we sought to enrich our search space with real interactions by analyzing variants that may be

Tree-ring-based annual precipitation reconstruction in Kalaqin, Inner Mongolia for the last 238 years

A tree-ring-width chronology of Pinus tabulaeformis from Kalaqin, Inner Mongolia was developed using modern dendrochronological techniques. Based on the results of correlation function analysis, the total precipitation from the previous August to current July was reconstructed for 1771-2008 AD with an explained variance of 49.3%. The reconstruction correlated well with the dryness/wetness series d

Enhanced deposition of cartilage oligomeric matrix protein is a common feature in fibrotic skin pathologies

Skin fibrosis is characterized by activated fibroblasts and an altered architecture of the extracellular matrix. Excessive deposition of extracellular matrix proteins and altered cytokine levels in the dermal collagen matrix are common to several pathological situations such as localized scleroderma and systemic sclerosis, keloids, dermatosclerosis associated with venous ulcers and the fibroprolif

Qualify of life and palliation predict survival in patients with chronic alveolar hypoventilation and nocturnal ventilatory support

Non-invasive positive pressure ventilation (NPPV) improves health-related quality of life (HRQL) in patients with chronic alveolar hypoventilation (CAH). We studied the prognostic impact of HRQL on survival in relation to clinical factors. Forty-four patients with CAH due to post-polio (12), scoliosis (11), post-tb (17) or other diagnoses (4) who received nocturnal NPPV were prospectively studied

Pain, power and patience - A narrative study of general practitioners' relations with chronic pain patients

Background: Chronic pain patients are common in general practice. In this study "chronic pain" is defined as diffuse musculoskeletal pain not due to inflammatory diseases or cancer. Effective patient-physician relations improve treatment results. The relationship between doctors and chronic pain patients is often dysfunctional. Consultation training for physicians and medical students can improve

Solving/understanding/evaluating the e-waste challenge through transdisciplinarity?

Transdisciplinarity has been accepted as a promising research approach to respond to complex real-world problems such as electronic waste (e-waste). Already one of the fastest growing waste streams, e-waste is a sustainability challenge that shadows the pervasive uses of electronic devices in contemporary society. Previous studies have not only shown the toxicity and risks inherent in the hazardou

Finding Our Way through Phenotypes.

Despite a large and multifaceted effort to understand the vast landscape of phenotypic data, their current form inhibits productive data analysis. The lack of a community-wide, consensus-based, human- and machine-interpretable language for describing phenotypes and their genomic and environmental contexts is perhaps the most pressing scientific bottleneck to integration across many key fields in b

Cross-linked DNA gels: Disruption and release properties

We report on the disruption of DNA gels cross-linked with ethylene glycol diglycidyl ether (EGDE), by sunlight exposure. The disruption over exposure time was characterized through the cumulative DNA release, the evolution in dry weight and extent of swelling, and also rheologically. The network disruption is shown to depend strongly on the degree of cross-linking density. Bovine serum albumin has
