Development of stable haploid strains and molecular genetic tools for Naumovozyma castellii (Saccharomyces castellii)

The budding yeast Naumovozyma castellii (syn. Saccharomyces castellii) has been included in comparative genomics studies, functional analyses of centromere DNA elements, and was shown to possess beneficial traits for telomere biology research. To provide useful tools for molecular genetic approaches, we produced stable haploid heterothallic strains from an early ancestral strain derived from the N

The effect of α-phenyl-tert-butyl nitrone (PBN) on free radical formation in transient focal ischaemia measured by microdialysis and 3,4-dihydroxybenzoate formation

α-phenyl-tert-butyl nitrone (PBN) reduces infarct size, improves recovery of brain energy metabolism and delays the secondary increase in extracellular potassium after focal ischaemia, presumably by trapping OH radicals. We investigated the effect of PBN on the formation of 3,4-dihydroxybenzoic acid (3,4-DHBA) as a measure of OH radical formation, during and following middle cerebral artery occlus

Exploring dementia management attitudes in primary care : a key informant survey to primary care physicians in 25 European countries

Background:: Strategies for the involvement of primary care in the management of patients with presumed or diagnosed dementia are heterogeneous across Europe. We wanted to explore attitudes of primary care physicians (PCPs) when managing dementia: (i) the most popular cognitive tests, (ii) who had the right to initiate or continue cholinesterase inhibitor or memantine treatment, and (iii) the rela

Lower age increases the risk of revision for stemmed and resurfacing shoulder hemi arthroplasty : A study from the Swedish shoulder arthroplasty register

Background and purpose — The number of patients where shoulder hemiarthroplasty (SHA) is an option is still substantial. Descriptive analyses performed by the Swedish Shoulder Arthroplasty Registry (SSAR) showed that while patients receiving SHA designs, i.e. resurfacing hemi (RH) and stemmed hemi (SH), reported similar shoulder functionality and quality of life, the revision rate for RH (12%) was

Mortality and cancer incidence among women with a high consumption of fatty fish contaminated with persistent organochlorine compounds

OBJECTIVES: The purpose of this study was to assess cancer incidence and cardiovascular mortality among women with a high dietary intake of fatty fish from the Baltic Sea (on the Swedish east coast), contaminated with persistent organochlorine compounds.MATERIAL AND METHODS: Cohorts of fishermen's wives from the Swedish east (1989 subjects) and west (6605 subjects) coasts were established. The mor

Characterizing gaze position signals and synthesizing noise during fixations in eye-tracking data

The magnitude of variation in the gaze position signals recorded by an eye tracker, also known as its precision, is an important aspect of an eye tracker’s data quality. However, data quality of eye-tracking signals is still poorly understood. In this paper, we therefore investigate the following: (1) How do the various available measures characterizing eye-tracking data during fixation relate to

User-related evaluation of ADAS and automated driving

Newly developed Advanced Driver Assistance Systems (ADAS) and Automated Driving offer support to the driver in his/her driving task. Besides driver comfort, these systems are expected to give significant safety improvements. However, the expected positive safety effects only will be achieved if the driver uses the system in the way it was intended to be used, he/she follows its recommendations and

Use of automated chest compression devices after out-of-hospital cardiac arrest in Sweden

Objective To evaluate the implementation of automated chest compression cardiopulmonary resuscitation (ACC-CPR) after out-of-hospital cardiac arrest (OHCA) in Sweden during the years 2011 through 2015. The association between ACC-CPR and 30-day survival was studied as a secondary objective. Methods The Swedish cardiopulmonary resuscitation registry is a prospectively recorded nationwide registry o

Method for probabilistic energy calculations : variable parameters

Building regulations in Sweden require that an energy calculation is done for every building to show that the building design meets the maximum specific energy use as outlined in the Swedish Building Code. The result of this energy calculation is always one number, for example a building might use 89 kWh/m2 year when the building regulation requires 90 kWh/m2 year. This level of reporting can lead

No effect of femoral canal jet-lavage on the stability of cementless stems in primary hip arthroplasty : a randomised RSA study with 6 years follow-up

Introduction: In contrast to cemented hip prostheses, the effect of washing the bone bed with jet-lavage prior to insertion of cementless stem components in primary hip arthroplasty (THA) is unclear. Jet-lavage potentially decreases the risk of fat embolisation during rasping and stem insertion and might help in avoiding bacterial contamination. An earlier animal study has shown less debris and be

The strategic focus of shippers and transport providers on greening transportation

Purpose To examine the strategic focus of shippers and transport providers (TPs) in reducing the environmental impact of transportation. Research questions: 1) To what extent are the green practices related to transportation described in literature being realised in practice by shippers and TPs? 2) How do shippers and TPs prioritise transportation compared to other initiatives for greening the sup

Chemical (in)homogeneity and atomic diffusion in the open cluster M 67

Context. The benchmark open cluster M 67 is known to have solar metallicity and an age similar to that of the Sun. It thus provides us with a great opportunity to study the properties of solar twins, as well as the evolution of Sun-like stars. Aims. Previous spectroscopic studies of M 67 reported possible subtle changes in stellar surface abundances throughout the stellar evolutionary phase, namel

APM Task Group 329 : Reference dose specification for dose calculations: Dose-to-water or dose-to-muscle?

Linac calibration is done in water, but patients are comprised primarily of soft tissue. Conceptually, and specified in NRG/RTOG trials, dose should be reported as dose-to-muscle to describe the dose to the patient. Historically, the dose-to-water of the linac calibration was often converted to dose-to-muscle for patient calculations through manual application of a 0.99 dose-to-water to dose-to-mu

Comparing chimpanzees' preparatory responses to known and unknown future outcomes

When humans plan for the future, we recognize not only that one particular event may occur, but that the future can have different, mutually exclusive possible outcomes. A recent study by Suddendorf et al. (Suddendorf 2017 Biol. Lett. 13, 20170170 (doi:10.1098/rsbl.2017.0170)) suggests that young children (less than 3 years) and apes lack this capacity, as demonstrated by their failure to cover ea

Alcohol Consumption in Obese Patients Before and After Gastric Bypass as Assessed with the Alcohol Marker Phosphatidylethanol (PEth)

Introduction: Roux-en-Y gastric bypass (RYGB) causes more rapid and enhanced absorption of alcohol. RYGB patients have also been reported to use more inpatient care for alcohol-related disease than do patients after other bariatric procedures. The present study was designed to evaluate alcohol consumption level before and after gastric bypass using a sensitive and specific alcohol biomarker. Mater

Ectodermal patterning in the avian embryo: epidermis versus neural plate

Ectodermal patterning of the chick embryo begins in the uterus and continues during gastrulation, when cells with a neural fate become restricted to the neural plate around the primitive streak, and cells fated to become the epidermis to the periphery. The prospective epidermis at early stages is characterized by the expression of the homeobox gene DLX5, which remains an epidermal marker during ga

The value of the Skåne Health-care Register : Prospectively collected individual-level data for population-based studies

Aims: This study aimed to examine the population-based Skåne Health-care Register (SHR) regarding feasibility for scientific research and also strengths and weaknesses. Methods: To analyse the feasibility of the SHR, we performed a bibliographic search for peer-reviewed articles based on SHR data from 2000 to 2018. To analyse strengths and weaknesses, we used original SHR data about coverage and v

Risk-tailored starting age of breast cancer screening based on women's reproductive profile : A nationwide cohort study

Background: Although reproductive history is recognised to affect the risk of breast cancer, current breast cancer screening guidelines do not consider risk differences by this important factor. As there is a need for an earlier screening in women at increased risk of breast cancer, we provided evidence-based risk-adapted starting age of screening based on different reproductive profiles. Material

Re-examination of accelerometer data processing and calibration for the assessment of physical activity intensity

This review re-examines the use of accelerometer and oxygen uptake data for the assessment of activity intensity. Accelerometers capture mechanical work, while oxygen uptake captures the energy cost of this work. Frequency filtering needs to be considered when processing acceleration data. A too restrictive filter attenuates the acceleration signal for walking and, to a higher degree, for running.

HLA associations in type 1 diabetes among patients not carrying high-risk DR3-DQ2 or DR4-DQ8 haplotypes

Type 1 diabetes is a complex disease where numerous genes are involved in the pathogenesis. Genes that account for approximately 50% of the familial clustering of the disease are located within or in the vicinity of the HLA complex on chromosome 6. Some DRB1, DQA1 and DQB1 genes are known to be involved, in addition to as yet unidentified HLA-linked genes. The DR4-DQ8 and DR3-DQ2 haplotypes are kn
