Katalys är ryggraden i många processer i vardagen. Även människokroppen styrs huvudsakligen av katalysatorer. Detta viktiga koncept tillåter oss att på ett miljövänligt sätt konvertera råmaterial som råolja och naturgas till värdefulla och oersättliga produkter, till exempel motorbränslen, läkemedel och agrokemikalier. En katalysprocess drivs av en katalysator, vilket således är en substans som, uNew classes of N-heterocyclic carbene-palladium(II) complexes containing either a vinyl group in different positions or an anthracene tag in the backbone of the N-heterocycle were synthesized and fully characterized. The vinyl based complexes were copolymerized with divinylbenzene to fabricate robust polymer-supported NHC-Pd(II) systems, while the anthracene based complexes were π-stacked onto the

Aims: The REPRISE IIE trial aimed to evaluate outcomes following transcatheter aortic valve implantation of the fully repositionable and retrievable LOTUS valve with a unique seal designed to minimise paravalvular leak (PVL). Methods and results: This prospective, multicentre study enrolled 250 patients with severe aortic stenosis considered high-risk for surgery by a multidisciplinary Heart Team.

Det var ett yrvaket och oförstående Europa som från och med 1991 såg konflikterna i Jugoslavien blossa upp i den egna europeiska ”bakgården”. Successivt under hela 1990-talet utvecklades upplösningskonflikten till en rad olika krig, och inte nog med att detta; stridigheterna uppfattades dessutom som ovanligt våldsamma, råa och obegripliga. Framför allt västerländska journalister, universitetsakade

The Helping Hand (HH) system is a novel grasp rehabilitation platform aimed at simplifying the clinical usage of wearable electrode arrays for neuromuscular electrical stimulation (NMES). In a randomized dose-matched, clinical study we evaluate usability and effectiveness of the HH treatment, and of other enriched upper limb rehabilitation treatments, and compare the outcomes. This paper shows the

BACKGROUND: Viral-induced asthma exacerbations, which exhibit both Th1-type neutrophilia and Th2-type inflammation, associate with secretion of Interleukin (IL)-1β. IL-1β induces neutrophilic inflammation. It may also increase Th2-type cytokine expression. We hypothesised that IL-1β is causally involved in both Th1 and Th2 features of asthma exacerbations. This hypothesis is tested in our mouse mo

BACKGROUND: Impaired antiviral interferon expression may be involved in asthma exacerbations commonly caused by rhinovirus infections. Allergy is a known risk factor for viral-induced asthma exacerbation, but little is known whether allergens may affect interferon responses.OBJECTIVE: Our hypothesis is that house dust mite (HDM) impairs viral stimulus-induced antiviral signalling.METHODS: Experime

Objectives: The progression and pathophysiology of neuropathy in impaired glucose tolerance (IGT) and type 2 diabetes (T2DM) is poorly understood, especially in relation to autophagy. This study was designed to assess whether the presence of autophagy-related structures was associated with sural nerve fiber pathology, and to investigate if endoneurial capillary pathology could predict the developm

Objective: The associations of energy, protein, carbohydrate, and fat intake with weight status up to the age of 5.5 years were prospectively assessed in The Environmental Determinants of Diabetes in the Young (TEDDY) study. Methods: Food record data (over 3 days) and BMI measurements between 0.25 and 5.5 years were available from 5,563 children with an increased genetic risk for type 1 diabetes f

Crime scene traces of various types are routinely sent to forensic laboratories for analysis, generally with the aim of addressing questions about the source of the trace. The laboratory may choose to analyse the samples in different ways depending on the type and quality of the sample, the importance of the case and the cost and performance of the available analysis methods. Theoretically well-fo

Cellular metabolite balance and mitochondrial function are under circadian control, but the pathways connecting the molecular clock to these functions are unclear. Peroxisome proliferator-activated receptor delta (PPARδ) enables preferential utilization of lipids as fuel during exercise and is a major driver of exercise endurance. We show here that the circadian repressors CRY1 and CRY2 function a

Objective: The standard surgical treatment for benign prostatic hypertrophy (BPH) is transurethral resection of the prostate (TURP). The aim of this study was to compare normal saline (NS) (0.9% sodium chloride) and Ringer’s acetate (RA) as irrigation fluid with regard to visibility, resection feasibility, coagulation and bleeding in bipolar TURP. Materials and methods: Twenty patients (mean age 7

To characterize type 2 diabetes (T2D)-associated variation across the allele frequency spectrum, we conducted a meta-analysis of genome-wide association data from 26,676 T2D case and 132,532 control subjects of European ancestry after imputation using the 1000 Genomes multiethnic reference panel. Promising association signals were followed up in additional data sets (of 14,545 or 7,397 T2D case an

Rhombomys opimus (R. opimus), a social rodent, is the main reservoir host for zoonotic cutaneous leishmaniasis (ZCL) in most parts of the Middle East and central Asia. The difficulties in monitoring rodent population patterns have hindered the effective application of preventive measures of ZCL. This study presents a spatially explicit agent-based simulation model of R. opimus behaviors that is in

An analytical method is presented, combining novel microcontact imprinting technique and capacitive biosensor technology for the detection of BSA. Glass cover slips were used for preparation of protein stamps. The microcontact-BSA imprinted gold electrodes were prepared in the presence of methacrylic acid (MAA) and poly-ethylene glycol dimethacrylate (PEGDMA) as the cross-linker by bringing the pr
