Popular Abstract in Swedish Det är en viktig uppgift för samhället att förebygga HIV och STI (sexuellt överförbara infektioner) bland ungdomar. Under de första åren av 1990-talet, när denna studie genomfördes, ökade dessa infektioner på ett oroväckande sätt. Detta gällde särskilt klamydiainfektionerna och nästan 25% av studenterna vid Lunds universitet rapporterade att de hade haft en konstaterad Slowing the incidence of HIV and STI among young people requires that they change their sexual behaviours. There is evidence that community-based interventions that target multiple levels of influence can be effective. In community mobilization different segments and sectors of a population are directly involved in problem identification and in the design and implementation of programs. The proces

In software engineering research, experiments are conducted to evaluate new methods or techniques. The experimentation as such is beginning to mature, but little effort is spent on learning across different studies, except for a few meta-analyses. Meta-analysis can be applied to a set of experiments with the same design. This paper discusses learning across a set of experimental studies on fault d

Deoxyribonucleoside kinases (dNKs) are essential in the mammalian cell but their 'importance' in bacteria, especially aquatic ones, is less clear. We studied two aquatic bacteria, Gram-negative Flavobacterium psychrophilum JIP02/86 and Polaribacter sp. MED152, for their ability to salvage deoxyribonucleosides (dNs). Both had a Gram-positive-type thymidine kinase (TK1), which could phosphorylate th

New, highly sensitive, biosensor concepts make it possible to assay biomacromolecules at concentrations that previously were far below the limit of detection. The previous generation of assays used in quality control situations during biotechnological production was designed primarily for monitoring target molecules, which typically appeared in high concentrations. Hence, novel analytical techniqu

The aim of the study was to determine and compare the degree of swelling and the swelling kinetics of poly(ethylene oxide) (PEO) hydrophilic matrix tablets without any additives for matrixes with different molecular weight polydispersities. A wide range of "mixed" polydisperse PEO tablets were obtained by mixing two PEO batches with average molecular weights of 10(5) and 2 x 10(6), respectively. T

Cellobiose dehydrogenase (CDH) is an emerging enzyme in the field of bioelectrocatalysis. Due to its flexible cytochrome domain, which acts as a built-in redox mediator, CDH is capable of direct electron transfer (DET) to electrode surfaces. This rare property is employed in mediatorless "third generation" biosensors. The ability of Corynascus thermophilus CDH to oxidize glucose under physiologica

Despite the huge increase in the number of management articles published during the three last decades, there is a serious shortage of high-impact research in management studies. We contend that a primary reason behind this paradoxical shortage is the near total dominance of incremental gap-spotting research in management. This domination is even more paradoxical as it is well known that gap-spott

‘Compensated dating’’ (CD) indicates the exchange of sexual intimacy for material compensation. This article investigates CD as receiving gifts for sex, such as luxuries, rent, travel, or monetary gifts. It proceeds by describing who engages in the practice and why, while comparing Russia with its cultural and linguistic neighbors, Ukraine and Belarus. A survey, which was answered by a representat

Red cell distribution width (RDW) has been associated with venous thromboembolism (VTE), but whether RDW is a predictor of first event of VTE is unknown. We investigated the association between RDW and incidence of first event of VTE in a population-based cohort.

Today, the majority of prostate tumours are detected at early stages with uncertain prognosis. Therefore, we set out to identify early predictive markers of prostate cancer with aggressive progression characteristics. We measured the expression of microRNAs (miRNA) using qRT-PCR in FFPE prostatic tissue samples from a Swedish cohort of 49 patients with prostate cancer and 25 without cancer and fou

The radiotherapy process is reviewed briefly and potential risks or pitfalls are identified. The focus is on modern advanced modalities in radiation therapy such as IMRT, VMAT, gating and tracking and also for the unknown to come. Existing methods, or quality controls (QC), or with better word barriers, are introduced at important steps of process with the purpose of prohibiting errors to continue

Autism spectrum disorder (ASD) is a common neurodevelopmental condition characterized by marked genetic heterogeneity. Recent studies of rare structural and sequence variants have identified hundreds of loci involved in ASD, but our knowledge of the overall genetic architecture and the underlying pathophysiological mechanisms remains incomplete. Glycine receptors (GlyRs) are ligand-gated chloride

Background: Joint pain and chronic back pain are highly prevalent in the aging population and have a large impact on life quality. As the underlying mechanisms are not fully understood, this exploratory cross-sectional study aimed to discover proteins and pathways associated with these two pain conditions in Swedish 70-year-old men. Methods: Plasma proteins (n = 720) were measured in participants

This paper explores an initiative by a local government in Rättvik, Sweden, to increase the consumption of local food in the municipal kitchens. It explores public procurement of local food as a way for local governments to address sustainability and climate goals while meeting residents’ demand for ‘good’ local food. Through a qualitative case study reviewing food and procurement policies across

Researchers have widely applied discharge simulation using artificial neural networks (ANNs) and have gained prominence in water resources. Morphological features, watershed urbanization, and climate change influence hydrological variables. Thus, data-driven models need to be able to identify the hydrological relationships without explicitly stating the physical processes. The main objectives of t

Creating software tools that address the needs of a wide range of decision-makers requires the inclusion of differing perspectives throughout the development process. Software tools for biodiversity conservation often fall short in this regard, partly because broad decision-maker needs may exceed the toolkits of single research groups or even institutions. We show that participatory, collaborative
