Mendelian breeding units versus standard sampling strategies: Mitochondrial DNA variation in southwest Sardinia
We report a sampling strategy based on Mendelian Breeding Units (MBUs), representing an interbreeding group of individuals sharing a common gene pool. The identification of MBUs is crucial for case-control experimental design in association studies. The aim of this work was to evaluate the possible existence of bias in terms of genetic variability and haplogroup frequencies in the MBU sample, due
A prospective, population-based study of 40000 women regarding host factors, UV exposure and sunbed use in relation to risk and anatomic site of cutaneous melanoma.
Prospective cohort studies about cutaneous melanoma (CM) risk are still few. Host factor- and UVR exposure data were collected prospectively by questionnaire in this population-based cohort study including 40000 Swedish born women, aged 25-64 years at enrolment (1990). Risk for CM (Cox regression and Stepwise Cox regression [SCR], hazard ratios [HRs] with 95 % Confidence Intervals [CI]) in relatio
Self-perceived performance and satisfaction with performance of daily activities in persons with multiple sclerosis following interdisciplinary rehabilitation.
Abstract Purpose: To assess self-perceived performance and satisfaction with performance of daily activities in persons with multiple sclerosis (MS) on admission to and at discharge from interdisciplinary rehabilitation. Method: A retrospective study with a pre-post design. Twenty-seven women and 16 men with MS (mean age 51 years; median EDSS 6.5) participated in an individualised, goal-oriented,
Assessing the reliability of Holocene relative palaeointensity estimates: a case study from Swedish varved lake sediments
We present palaeomagnetic secular variation and relative palaeointensity estimates from multiple sediment cores recovered from a varved lake sediment sequence in Kalksjon, a lake in central west Sweden. Alternating field demagnetization of discrete samples reveals natural remanent magnetizations dominated by a stable, single component. Magnetic grain size indicators-which include Day plots and fir
Dietary Flavonoid Intake and Esophageal Cancer Risk in the European Prospective Investigation into Cancer and Nutrition Cohort
We prospectively investigated dietary flavonoid intake and esophageal cancer risk in the European Prospective Investigation into Cancer and Nutrition (EPIC) cohort. The study included 477,312 adult subjects from 10 European countries. At baseline, country-specific validated dietary questionnaires were used. During a mean follow-up of 11 years (1992-2010), there were 341 incident esophageal cancer
Long-lasting consequences of elevated yolk testosterone for metabolism in the zebra finch.
Abstract Resting metabolic rate is a common way of quantifying the cost of living in endothermic animals. The trait often makes up a substantial part of an animal's energy budget and can also be related to sustainable peak work rate as well as to daily energy expenditure. Studies have shown that metabolic rates are often heritable, but much of the variation seems to be caused by other factors (e.g
Effects of oestradiol and raloxifene on the induction and effector phases of experimental postmenopausal arthritis and secondary osteoporosis.
Oestradiol and the selective oestrogen receptor modulator (SERM) raloxifene have been shown to ameliorate collagen-induced arthritis (CIA) in rats and in mice. One aim was to investigate if raloxifene exerts its anti-arthritic and anti-osteoporotic effects during the induction or effector phase of arthritis. A second aim was to analyse if raloxifene activates the oestrogen response element (ERE) t
OARSI Clinical Trials Recommendations: Key analytic considerations in design, analysis, and reporting of randomized controlled trials in osteoarthritis.
To highlight methodologic challenges pertinent to design, analysis, and reporting of results of randomized clinical trials in OA and offer practical suggestions to overcome these challenges. The topics covered in this paper include subject selection, randomization, approaches to handling missing data, subgroup analysis, sample size, and issues related to changing design mid-way through the study.
Modelling the dynamic dose response of an nMAG polymer gel dosimeter.
Gel dosimetry measures the absorbed radiation dose with high spatial resolution in 3D. However, recently published data show that the response of metacrylic-based polymer gels depends on the segmented delivery pattern, which could potentially be a considerable disadvantage for measurements of modern dynamic radiotherapy techniques. The aim of this study is to design a dynamic compartment model for
Latitudinal gradients and the shaping of life-history traits in a gregarious caterpillar
The present study aimed to investigate how the impact of several factors linked to geography would shape life-history traits in a gregarious species, using the pine processionary moth (PPM) Thaumetopoea pityocampa as a model system. PPM has a wide geographical distribution over the Mediterranean Basin, and it is a strictly gregarious species throughout larval development, where the total reproduct
Maternal smoking during pregnancy and daughters' risk of gestational diabetes and obesity.
AIMS/HYPOTHESIS: The primary aim of the study was to investigate the risk of developing gestational diabetes in women who were exposed to tobacco smoke in utero. Secondary aims were to assess the risk of obesity and non-gestational diabetes. METHODS: Data were retrieved from the Medical Birth Register of Sweden for women who were born in 1982 (when smoking data were first registered) or later and
Discourses of counter-Islamic-threat mobilization in post 9/11 documentaries
This article critically studies documentaries focusing on the "Islamic terrorist threat", produced in the US and in Western Europe. The particular films relate to the discourses of the growing far right political movements in liberal democracies. The article analyzes the communicational tactics deployed by the filmmakers for counter-terrorist mobilization of "Westerners". The films' producers obje
Aberrant recombination and repair during immunoglobulin class switching in BRCA1-deficient human B cells.
Breast cancer type 1 susceptibility protein (BRCA1) has a multitude of functions that contribute to genome integrity and tumor suppression. Its participation in the repair of DNA double-strand breaks (DSBs) during homologous recombination (HR) is well recognized, whereas its involvement in the second major DSB repair pathway, nonhomologous end-joining (NHEJ), remains controversial. Here we have st
Gendering Al-Nakba : Elderly Palestinian Refugees' Stories and Silences about Dying Children
This article builds on the life-stories of elderly Palestinian refugees, collected in the West Bank in 2003-2004. It discusses accounts about flight in 1948 (i.e. al-Nakba) and pays particular interest to stories as well as silences about dying children. The article argues that men and women remembered their flight differently and that the gendered experiences of flight influenced understandings o
Multispectral guided fluorescence diffuse optical tomography using upconverting nanoparticles
We report on improved image detectability for fluorescence diffuse optical tomography using upconverting nanoparticles doped with rare-earth elements. Core-shell NaYF4 : Yb3+/Er3+ @ NaYF4 upconverting nanoparticles were synthesized through a stoichiometric method. The Yb3+/Er3+ sensitizer-activator pair yielded two anti-Stokes shifted fluorescence emission bands at 540 nm and 660 nm, here used to

Effect of Common Genetic Variants Associated with Type 2 Diabetes and Glycemic Traits on α- and β-cell Function and Insulin Action in Man.
Although meta-analyses of genome-wide association studies have identified more than 60 single nucleotide polymorphisms (SNPs) associated with type 2 diabetes and/or glycemic traits, there is little information whether these variants also affect α-cell function. The aim of the present study was to evaluate the effects of glycemia-associated genetic loci on islet function in vivo and in vitro. We st
