Rapporten sammanfattar fjärilsinventeringar utförda 2022 inom Biogeografisk uppföljning som drivs av Naturvårdsverket. I fjällområdet kunde totalt 35 ytor inventeras. Sammanlagt noterades 38 högnordiska blåvingar på 12 av 16 inventerade ytor, 34 dvärgpärlemorfjärilar på 14 av 17 ytor och 3 fjällsilversmygare noterades på 2 av 3 inventerade ytor. Svartfläckig blåvinge observerades på 23 av 56 inven

Background: No studies to specifically determine the prevalence of contact allergy to acrylates/methacrylates in patch tested populations have been published. Objectives: To determine the prevalence of acrylate/methacrylate allergy in all patients tested to the baseline patch test series. Methods: Five acrylate/methacrylate allergens (2-hydroxyethyl methacrylate, methyl methacrylate, ethylene glyc

An adsorbent was developed from mature leaves and stem bark of the Neem (Azadirachta indica) tree for removing zinc from water. Adsorption was carried out in a batch process with several different concentrations of zinc by varying pH. The uptake of metal was very fast initially, but gradually slowed down indicating penetration into the interior of the adsorbent particles. The data showed that opti

Methodological aspects of planar gamma scintigraphy used to quantify pulmonary aerosol deposition were investigated using an experimental dry powder formulation. Particles of micronized salbutamol sulphate were labelled with technetium-99m and admixed to an ordered mixture of unlabelled micronized salbutamol sulphate and larger carrier particles of lactose. The radioaerosol was administered to 24

Objective: To estimate whether obese women have an increased risk of orofacial clefts in their offspring, compared with average-weight women. Design and Participants: The study was based on information on maternal body mass index (BMI) collected in early pregnancy and on the existence of orofacial clefts in the offspring, ascertained from multiple sources. The study included 1686 women who had inf

AimThe aim of this study was to investigate differences in mortality up to 1year of age in extremely preterm infants (before 27weeks) born in seven Swedish healthcare regions. MethodsNational prospective observational study of consecutively born, extremely preterm infants in Sweden 2004-2007. Mortality was compared between regions. Crude and adjusted odds ratios and 95% CI were calculated. Results

The properties of the amyloid-beta peptide that lead to aggregation associated with Alzheimer's disease are not fully understood. This study aims at identifying conformational differences among four variants of full-length Abeta42 that are known to display very different aggregation properties. By extensive all-atom Monte Carlo simulations, we find that a variety of beta-sheet structures with dist

Background: Persistent left superior vena cava (LSVC) is one of the common anomalies of the systemic veins. Its prevalence is 0.1-0.3% in the general population and is more common with congenital heart disease (CHD). The importance of detecting persistent LSVC prior to cardiac surgery is paramount for systemic veins cannulations. Aim: The aim was to evaluate the prevalence of persistent LSVC in pa

Background The aim of this study was to describe the Variable anatomy in the anastomosis between the umbilical arteries for better understanding of the physical characteristics of the umbilical Row velocity waveform (FVW). Methods. The arterial system of 67 placentas from pregnancies with normal umbilical FVW and resulting in a full-term AGA infant was visualized by angiography. The method allowed

This study was based on 459 adult patients with deep, high-grade, soft tissue sarcoma of extremities or trunk wall reported to the Scandinavian Sarcoma Group Register (1986-1993). All patients had their definitive surgery for primary tumor at a sarcoma center. The median follow-up was 7.5 (3-12) years. 204 patients are still alive. 68 patients had amputations and 391 underwent limb-sparing surgery

The purpose of this investigation was to evaluate the bone turnover by using bone metabolic markers in relation to previous fracture history and independent of bone mass. Patients and controls were recruited from a population-based study of 193 women, all living in the same city and aged 60, 70, and 80 years. The bone mineral content (BMC) was measured bilaterally in the distal forearm by single-p

The remarkable variation in plumage and morphological characters in the redpoll complex Carduelis flammea-hornemanni has puzzled taxonomists for several decades. In contrast, molecular studies have not revealed any genetic differentiation among the phenotypic redpoll forms. This could either be a result of high present-day gene flow or morphological differentiation following a rapid and recent pop
