Popular Abstract in Swedish HIV är en av de dödligaste farsoterna i världen och 30-40 miljoner människor beräknas ha dött AIDS. Genom att konstant förändra sig ligger viruset hela tiden ett steg före immunförsvaret, och immunförsvaret klarar därför inte av att bekämpa infektionen. HIV skiljer sig också från andra virus genom att det drabbar och långsamt utplånar immunförsvaret. Det gör att HIV kanThe two genetically related human lentiviruses known today, HIV-1 (which is pandemic) and HIV-2 (which mainly is confined to West Africa), are the causative agents of AIDS. Progressive immune dysfunction and AIDS develop in most cases of untreated HIV-1 infection, but only in approximately 25-30% of HIV-2 infected individuals. The V1-V3 region of the HIV-1 env gp120 is important for HIV-1 corecept

In recent years, systems for resource allocation in academic research based on performance indicators have been introduced in many European countries (Hicks, 2012). Today, we are at a point where the use of bibliometrics based indicators for research evaluation and resource allocation more or less permeates academic systems on all levels and across the world. The implementation—and the effects of

Based on various activities in which pupils gain knowledge about forest-related challenges and opportunities as well as forestry, they would design plans to deal with those problems. After a firs

Bladder cancer is the ninth most common type of cancer globally, and the projected number of deaths is estimated to almost double by the year 2040. Immunotherapy with checkpoint inhibitors has revolutionized treatment of bladder cancer and can achieve durable responses; however, only a minority of patients respond. By identifying additional targets and treatment combinations, more patients could b

INTRODUCTION: Survival and healthcare for patients with congenital heart disease have improved, and the number of pregnancies among women of childbearing age with congenital heart disease has increased. Our aim was to investigate obstetric outcomes in a large retrospective, national registry study of women with congenital heart disease compared to controls.MATERIAL AND METHODS: The study included

BACKGROUND: The beneficial effects of hormonal therapy in stimulating spermatogenesis in patients with non-obstructive azoospermia (NOA) and either normal gonadotrophins or hypergonadotropic hypogonadism prior to surgical sperm retrieval (SSR) is controversial. Although the European Association of Urology guidelines state that hormone stimulation is not recommended in routine clinical practice, a

Background: Somatostatin receptor 68Ga PET imaging is standard for evaluation of a patient’s suitability for 177Lu peptide receptor radionuclide therapy of neuroendocrine tumours (NETs). The 68Ga PET serves to ensure sufficient somatostatin receptor expression, commonly evaluated qualitatively. The aim of this study is to investigate the quantitative relationships between uptake in 68Ga PET and ab

Biomass is an environmentally friendly renewable energy source and carbon-neutral fuel alternative. Direct combustion/gasification of biomass in the dense particle-fluid system is an important pathway to biomass energy utilization. To efficiently utilize biomass for energy conversion, a full understanding of biomass thermal conversion in lab/industrial-scale equipment is essential. This thesis aim

The increasing number of tourists to urban destinations such as, Amsterdam, Barcelona, Dubrovnik, Hong Kong, and Rio de Janeiro cause a range of problems related to conflicts between visitors and residents, lack of accessibility to different areas in the cities, and damage to green spaces (Joppe, 2018; Novy, 2018). The growth focused strategies of urban destinations have created an unstainable tou

Popular Abstract in English Freezing is a commonly used method of preserving food products including fruits and vegetables. A fresh-like texture and appealing visual appearance of frozen and thawed plant food products are of key importance for customer acceptance. Therefore, the food industry is constantly looking for ways to improve freezing techniques, especially for sensitive plant tissues suchFreezing is a widely used method of preserving food products. Efforts are currently being directed towards improving the quality of the sensitive tissues of plant foods such as leaves, after freezing and thawing. One of the methods under investigation is the combination of vacuum impregnation (VI) with cryoprotectants and the application of a pulsed electric field (PEF) to the plant tissue prior t

Popular Abstract in Swedish Med snabbare och pålitligare analysresultat finns stora möjligheter till ett ökat utnyttjande av avfallsresurser för produktion av förnybar energi. Resultat från min forskning gör det möjligt att analysera råvaror för biogasproduktion med större säkerhet och med möjligheten att få upp till nio gånger snabbare resultat. Produktion av biogas har under den senaste tiden öA sustainable treatment of organic wastes, generation of renewable energy, reduction of green house gas emissions, limiting the eutrophication and closing the nutrient cycles are several environmental challenges for which anaerobic digestion may be a suitable solution. There is today a large amount of available organic waste materials that could serve as potential feedstock for biogas production.

Anaerobic digestion (AD) has gained increasing attention nowadays as an approach for both waste treatment and renewable energy generation. Currently, many different types of materials can be used as feedstock for biogas production via AD process, but their biodegradability (based on methane yield, BDCH4) and potential to produce biogas might vary significantly, and these properties are key paramet

INTRODUCTION: Since the last two decades, there has been a dramatic rise in caesarean sections (CS) throughout the world. This increase has been seen even in Europe, where rates vary significantly from 17% in Northern Europe to 56% in the South. Although, CS can be a lifesaving intervention when medically necessary, non-essential CS are associated with short- and long-term complications for both t

Background: We hypothesised that observed annual incidence rates of ANCA-associated vasculitis (AAV) are driven bysporadic short-term, high-intensity rates characterised as clusters of diagnosis events in time. Using data from Ireland, Swedenand Spain, we performed a changepoint analysis to discover time intervals with high and low rates of vasculitis diagnosis.Methods: We recruited 417 patients f

Background: Quantitative cardiovascular magnetic resonance (CMR) first pass perfusion maps are conventionally acquired with 3 short-axis (SAX) views (basal, mid, and apical) in every heartbeat (3SAX/1RR). Thus, a significant part of the left ventricle (LV) myocardium, including the apex, is not covered. The aims of this study were 1) to investigate if perfusion maps acquired with 3 short-axis view
