Gruv- och ballastindustrin utgör en mycket viktig sektor i den svenska ekonomin. Där gruvindustrin operar på den globala arenan medan sten branschen operar på regional/lokal basis. Efterfrågan av metaller- och byggnadsmaterial har ökat under det senaste decenniet och mängden fasta mineraler och stenar som tas ut ur jordskorpan är nästan 80 miljarder ton per år, med ballast som den största delen.DeThe mining and quarrying industries represent a highly important sector of the Swedish economy. The mining industry operates globally, whereas the quarrying industry operates on a regional/local basis. Demands for metal and construction aggregates have increased over the last decade, and almost 80 billion tons of solid minerals and rocks are extracted from the earth’s crust each year. Construction

Background: Post-covid syndrome is an emerging condition involving a wide range of symptoms, including high rates of poor mental health. The diagnostic relevance and clinical severity of these symptoms are largely unknown, and evidence for treatment of post-covid mental health symptoms is lacking. This protocol describes a pilot randomized clinical trial, primarily aiming to assess feasibility, pa

Objectives Physical inactivity and sedentary behaviour are associated with higher breast cancer risk in observational studies, but ascribing causality is difficult. Mendelian randomisation (MR) assesses causality by simulating randomised trial groups using genotype. We assessed whether lifelong physical activity or sedentary time, assessed using genotype, may be causally associated with breast can

The web of relationships between wellbeing and the environments in which people live has long been recognized. However, relatively little research has been conducted about end-of-life surroundings from the perspective of the dying person. In this study, we investigate which aspects of their surroundings are particularly meaningful for the people inhabiting them in the last phases of life, based on

AIMS/HYPOTHESIS: Salt-inducible kinases (SIKs) are related to the metabolic regulator AMP-activated protein kinase (AMPK). SIK2 is abundant in adipose tissue. The aims of this study were to investigate the expression of SIKs in relation to human obesity and insulin resistance, and to evaluate whether changes in the expression of SIKs might play a causal role in the development of disturbed glucose

OBJECTIVE: Systemic administration of immunotherapeutics often gives rise to severe side effects. A local deposition, using secretory lysosomes of hematopoietic cells as vehicles for delivery, can overcome this problem. In the present study, the validity of this concept was investigated using retroviral transduction of the human soluble tumor necrosis factor-alpha receptor 1 (hsTNFR1) into murine

Several tests of human conscious knee proprioception have been described, but there is no consensus or reference standard established. Difficulties remain in the separation of information originating from muscles, tendons, and joints, and the tests cannot discriminate between loss of afferent signals or altered activity in the remaining receptors. There is convincing evidence from several descript

Background: Caldicellulosiruptor saccharolyticus has attracted increased interest as an industrial hydrogen (H2)producer. The aim of the present study was to develop a kinetic growth model for this extreme thermophile. The model is based on Monod kinetics supplemented with the inhibitory effects of H2 and osmotic pressure, as well as the liquid-to-gas mass transfer of H2. Results: Mathematical exp

PurposeIt is not known if mammographic breast compression of a primary tumor causes shedding of tumor cells into the circulatory system. Little is known about how the detection of circulating biomarkers such as circulating tumor cells (CTCs) or circulating tumor DNA (ctDNA) is affected by breast compression intervention.MethodsCTCs and ctDNA were analyzed in blood samples collected before and afte

The early B cell factor (EBF) is a transcription factor shown crucial for the development of B lymphocytes. The protein is expressed from the earliest stages of B cell development until the mature B cell stage, but the control elements responsible for the regulation of the gene are unknown. In this study, we report of the identification of a promoter region flanking the EBF gene. Several transcrip

Naturvårdsverket har i regleringsbrevet för år 2009 fått i uppdrag av regeringen att redovisa vilka element som verket bedömer bör ingå i övervakningen av GMO som introduceras i miljön för försök eller i kommersiell odling. I samråd med Miljödepartementet har uppdraget avgränsats till att inte inkludera försök, utan enbart beröra kommersiell odling. Denna rapport utgör redovisningen av uppdraget.I

Sensitizing capacities and cross-reactivity patterns of some diisocyanates and amines using the guinea-pig maximization test. Can p-phenylenediamine be used as a marker for diisocyanate contact allergy?

BACKGROUND: Detailed assessments of mortality patterns, particularly age-specific mortality, represent a crucial input that enables health systems to target interventions to specific populations. Understanding how all-cause mortality has changed with respect to development status can identify exemplars for best practice. To accomplish this, the Global Burden of Diseases, Injuries, and Risk Factors

The development of genetic counseling in Sweden in the field of medical genetics emerged in the 1950s, at the department of medical genetics at Uppsala University. The head of department, Jan Arvid Böök, a member of the WHO expert committee on Human Genetics, early realized the importance of studies in broadly distributed genetic diseases, along with genetic counseling.

Isotopic proveniencing has been applied to human inhumations and cremations as well as fauna from the Viking Age site of Birka and the surrounding Mälaren region, located in east-central Sweden. Human enamel frominhumations has been measured for strontium, oxygen, and carbon isotope ratios (petrous bone from cremations was measured for strontium only) to obtain information on mobility and diet. Se

Protein S deficiency is a known risk factor for thrombosis. The coexistence of phenotypic type I (reduction in total and free antigen) and type III (reduction in free antigen only) protein S deficiencies in 14 of 18 families was recently reported. We investigated the cause of this phenotypic variation in the largest of these families (122 family members, including 44 affected individuals) using bo

Background: Bilberries from Sweden, rich in polyphenols, have shown cholesterol-lowering effects in small studies, and the cholesterol-lowering properties of oats, with abundant beta-glucans and potentially bioactive phytochemicals, are well established. Both may provide cardiometabolic benefits following acute myocardial infarction (AMI), but large studies of adequate statistical power and approp

Light/dark cycles play an essential role in people's performance, mood and daily rhythm. This study aimed to evaluate an early prototype of a personalised home lighting system including body-worn loggers. A convenience sample (N = 28) wore the devices for 23 h in the field and were given a demonstration of the lighting system components. Participants reported on questionnaires their acceptance of
