Serum albumin adducts, DNA adducts and micronuclei frequency measured in benzo[a]pyrene-exposed mice for estimation of genotoxic potency

The environmental and food contaminant, benzo[a]pyrene {B[a]P, a polycyclic aromatic hydrocarbon (PAH)}, is classified as a human carcinogen by the International Agency for Research on Cancer. The carcinogenicity of B[a]P is linked to the formation of electrophilic metabolites, namely B[a]P-diol epoxides (BPDEs) occurring as stereoisomers. In this work, we quantified the metabolic formation of BPD

The relationship between accessibility and price – The case of Swedish food stores

Food accessibility has been an important issue for as long as there has been human civilisation. Today, food, at least in the wealthier parts of the world, is accessible to most people. However, there are concerns regarding the market power of major retailers and the availability of affordable food among certain population groups. In this paper, I investigate how well accessibility, the ease with

Climate effects on the onset of flowering in the United Kingdom

Background: A warmer climate has consequences for the timing of phenological events, as temperature is a key factor controlling plant development and flowering. In this study, we analyse the effects of the long-term climate change and an extreme weather event on the first flowering day (FFD) of five spring-flowering wild plant species in the United Kingdom. Citizen science data from the UK Woodlan

The metabolic syndrome - What is it and how should it be managed?

A cluster of metabolic factors have been merged into an entity named the metabolic syndrome. Although the characteristics of this syndrome have varied over time the presently used definition was established in 2009. The presence of three abnormal findings out of five components qualifies a person for the metabolic syndrome: elevated waist circumference, elevated triglycerides, reduced high-density

Data for assessment of soil water extractable and percolation water dissolved organic carbon in watersheds

(“Sources of soil dissolved organic carbon in a mixed agricultural and forested watershed in Rwanda”, [6]) This data article presents water extractable organic carbon (WEOC), percolation water dissolved organic carbon (pDOC), and mean antecedent precipitation indices (API) and mean antecedent temperature (MAT) data. The article also presents edaphic properties such soil texture elements, total org

Determining the Predominant Lesion in Patients With Severe Aortic Stenosis and Coronary Stenoses : A Multicenter Study Using Intracoronary Pressure and Flow

BACKGROUND: Patients with severe aortic stenosis (AS) often have coronary artery disease. Both the aortic valve and the coronary disease influence the blood flow to the myocardium and its ability to respond to stress; leading to exertional symptoms. In this study, we aim to quantify the effect of severe AS on the coronary microcirculation and determine if this is influenced by any concomitant coro

Performing the Other : Report on workshops on Copying and Imitating

Performing The Other. Report on workshops on observing and imitatingThe lecture will present the experience, results and challenges arising within a series of workshops that were investigating the role of observation, copying and imitation in the actor’s work, activities close to Brecht’s aesthetic focus. Claiming that “people will observe you, in order to investigate how well you have observed”,

Conductive and enzyme-like silk fibers for soft sensing application

A combination of supercritical carbon dioxide (scCO2) impregnation of pyrrole and sonochemical transformation of permanganate (KMnO4) was used to impart conductive and catalytic properties to silk fibers. The results indicated that the conductivity (from polypyrrole –PPy) and catalytic activities (from manganese dioxide –MnO2) were independent and complementary within the processing parameters use

Controversy, Facts and Assumptions: Lessons from Estimating Long Term Growth in Nigeria, 1900–2007

This article contributes to the debates surrounding "New African Economic History" by exploring the feasibility of constructing a time series of economic growth in Nigeria spanning the whole twentieth century. Currently most datasets for African economies only go back to 1960. The sources for their creation exist, but these valuable colonial data remain underutilized. This is an exploratory paper

Clinical significance of stromal ER and PR expression in periampullary adenocarcinoma

Background: Tamoxifen treatment has previously been reported to confer life-prolonging effects in patients with advanced pancreatic cancer, and most evidently so in women. None of these trials did however include biomarkers, and the relevance of female hormone signaling in pancreatic or other periampullary adenocarcinoma remains largely unexplored. The aim of this study was to examine the extent a

Förord

Detta är den nionde skriften i forskningsprogrammet Vetenskap och beprövad erfarenhets (VBE:s) skriftserie om begreppet vetenskap och beprövad erfarenhet. Denna gång är skriften resultatet av ett pågående samarbete med forskningsprogrammet Foresight vid Malmö universitet. Foresights forskning är inriktad på att hitta nya verktyg för att identifiera patienter som löper ökad risk för karies och tand

Chemical Heterogeneity of Mg, Mn, Na, S, and Sr in Benthic Foraminiferal Calcite

The chemical composition of fossil foraminiferal shells (tests) is widely used as tracers for past ocean chemistry. It is, therefore, important to understand how different (trace) elements are transported and incorporated into these tests from adjacent seawater. The elemental distribution within the walls of foraminiferal tests might be used to differentiate between proposed transport mechanisms.

Effect of the addition of thermostable and non-thermostable type 2 resistant starch (RS2) in cake batters

There is interest in increasing the consumption of foods with high dietary fiber content due to the health problems associated with its low intake. Plantain (Musa paradisiaca L.) flour (PF) (non-thermostable) and Hi-Maize 260 (HA) (thermostable) were used as resistant starch (RS) sources to elaborate blends with wheat (WF) and rice flours (RF) in a 50:50 ratio. Five blends were prepared (PF-WF, PF

Comparison of Performance and Effectiveness of Vertical Borehole Heat Exchanger Collectors

The number of heating and cooling system using vertical borehole heat exchangers is increasingly rapidly in Sweden. Currently, there are over 600,000 installations, mostly using U-tube ground collectors. In recent years, several new ground collectors with innovative designs and configurations have been launched. They claim to have superior performance and competitive advantages over the convention

Floating Thermal Piles in Soft Sensitive Clays

Thermal piles are building foundation piles which, in addition to transferring the load of the building to the ground, are also used as heat exchangers to provide thermal exchange with the ground. This article shortly presents field testing of thermal piles installed in soft sensitive clay in Gothenburg. The aim of the field tests is to study the thermo-mechanical response of the heating and cooli

Hemogenic Reprogramming of Human Fibroblasts by Enforced Expression of Transcription Factors

The cellular and molecular mechanisms underlying specification of human hematopoietic stem cells (HSCs) remain elusive. Strategies to recapitulate human HSC emergence in vitro are required to overcome limitations in studying this complex developmental process. Here, we describe a protocol to generate hematopoietic stem and progenitor-like cells from human dermal fibroblasts employing a direct cell

Bullying and Pain in School-Aged Children and Adolescents : A Cross-Sectional Study

Bullying is defined as repeated and unwanted aggressive behavior involving a power imbalance and hurt children and adolescents’ socioemotional functioning. The aim is to investigate associations between pain (headache, stomach pain, backache, and neck/shoulder pain) and bullying among school-aged children and adolescents. This cross-sectional school-based survey comes from the Icelandic data set i

The impact of endurance training and table soccer on brain metabolites in schizophrenia

Higher glutamate and glutamine (together: Glx) and lower N-acetyl-aspartate (NAA) levels were reported in schizophrenia. Endurance training normalizes NAA in the hippocampus, but its effects on other metabolites in the brain and the relationship of metabolites to clinical symptoms remain unknown. For 12 weeks, 20 schizophrenia inpatients (14 men, 6 women) and 23 healthy controls (16 men, 7 women)
