Genetic studies promise to provide insight into the molecular mechanisms underlying type 2 diabetes (T2D). Variants associated with T2D are often located in tissue-specific enhancer clusters or super-enhancers. So far, such domains have been defined through clustering of enhancers in linear genome maps rather than in three-dimensional (3D) space. Furthermore, their target genes are often unknown.
Esophageal perforation is associated with significant mortality, and this may markedly increase with advanced age. This multicenter study investigates this issue in patients older than 80 years. Data on 33 patients >80 years old who underwent conservative (10 patients), endoclip (one patient), stent grafting (11 patients), or surgical treatment (11 patients) for esophageal perforation were collect
The detailed pathways of photoactivity on ultrafast time scales are a topic of contemporary interest. Using a tabletop apparatus based on a laser plasma X-ray source and an array of cryogenic microcalorimeter X-ray detectors, we measured a transient X-ray absorption spectrum during the ferrioxalate photoreduction reaction. With these high-efficiency detectors, we observe the Fe K edge move to lowe
CsrRS (or CovRS) is a two-component system implicated in the control of multiple virulence determinants in the important human pathogen, group A Streptococcus (GAS). Earlier studies suggested that extracellular Mg(2+) signalled through the presumed sensor histidine kinase, CsrS. We now confirm those findings, as complementation of a csrS mutant restored Mg(2+)-dependent gene regulation. Moreover,
Adenylate kinases (AKs) play important roles in nucleotide metabolism in all organisms and in cellular energetics by means of phosphotransfer networks in eukaryotes. The crystal structure of a human AK named AK6 was determined by in-house sulfur single-wavelength anomalous dispersion phasing methods and refined to 2.0-A resolution with a free R factor of 21.8%. Sequence analyses revealed that huma
Local environmental and ecological conditions are commonly expected to result in local adaptation, although there are few examples of variation in phenotypic selection across continent-wide spatial scales. We collected standardized data on selection with respect to the highly variable plumage coloration of pied flycatcher (Ficedula hypoleucaPall.) males from 17 populations across the species' bree
Summary form only given. Spectra were recorded from a fluorescent light tube under a number of experimental conditions and using different spectroscopic techniques. The motivation of the work was to use spectroscopic techniques for plasma diagnostics purposes. The spectrometers used were a high resolution echelle based instrument and a Fourier transform spectrometer in Lund and a low-resolution in
Popular Abstract in Swedish Polyomavirus är en familj av små DNA-virus som har onkogena egenskaper i försöksdjur i celler in vitro. De humana polyomavirusen BK virus (BKV) och JC virus (JCV) infekterar en stor del av befolkningen. Ungefär 70-80 % av vuxna är seropositiva, har antikroppar mot BKV och JCV. Primär infektion inträffar oftast under barndomen och är ofta subklinisk. Efter primära infektThe human polyomaviruses BKV and JCV are endemic and infect > 70% of population worldwide. Primary infections occur during childhood and are largely subclinical. Following primary infection, both viruses persist as latent infections in the kidneys and B lymphocytes. Under conditions of severe immunosuppression like leukaemia, organ transplantation and AIDS, the viruses can reactivate and cause dis
The identification of unknown genomic flanking DNA sequences can be used for the molecular monitoring of retro-, lenti- and foamyviral integration, transgenes in early embryogenesis, insertional mutagenesis, cell fate, and stem cell plasticity. Most existing methods reflect shortcomings in sensitivity and or specificity, thus limiting genomic sequencing of unknown flanking DNA to clonal preparatio
Handheld mobile phones were introduced in Sweden during the late 1980s. The purpose of this population-based, case-control study was to test the hypothesis that long-term mobile phone use increases the risk of brain tumors. The authors identified all cases aged 20-69 years who were diagnosed with glioma or meningioma during 2000-2002 in certain parts of Sweden. Randomly selected controls were stra
Glial cell line-derived neurotrophic factor (GDNF) exhibits potent effects on survival and function of midbrain dopaminergic (DA) neurons in a variety of models. Although other growth factors expressed in the vicinity of developing DA neurons have been reported to support survival of DA neurons in vitro, to date none of these factors duplicate the potent and selective actions of GDNF in vivo. We r
T follicular helper (Tfh) cells represent a recently defined CD4(+) T cell subset characterized by the expression of the chemokine receptor CXCR5 and an enhanced ability to support B cells to mount antibody responses. Here, we demonstrate that lymph-node-resident CXCR5(+) Tfh cells and gut-homing integrin alpha(4)beta(7)-expressing T helper cells are generated as separate subsets in the gut-draini
Popular Abstract in Swedish ”Vardagliga problem hos män med prostata cancer. Upplevelser av problem med att kasta vatten, bära kateter och problem i sexuallivet”. Avhandlingens övergripande syfte var att undersöka förekomsten av vardagliga problem hos män med prostatacancer, problemens relation till livskvalitet, till känsla av sammanhang och relationen mellan dessa faktorer, samt att jämföra medThe aim was to investigate the presence of everyday problems in men with prostate cancer, their relation to health-related quality of life, HRQOL, and sense of coherence, SOC, and to compare with men with benign prostatic hyperplasia, BPH, and a sample from the general population. The aim also was to investigate what nursing care needs there were in men with prostate cancer and how these were met
Objective Systemic sclerosis (SSc) is associated with a significant reduction in life expectancy. A simple prognostic model to predict 5-year survival in SSc was developed in 1999 in 280 patients, but it has not been validated in other patients. The predictions of a prognostic model are usually less accurate in other patients, especially from other centres or countries. A study was undertaken to v
Background: Congenital anomalies are the fifth leading cause of mortality in children younger than 5 years globally. Many gastrointestinal congenital anomalies are fatal without timely access to neonatal surgical care, but few studies have been done on these conditions in low-income and middle-income countries (LMICs). We compared outcomes of the seven most common gastrointestinal congenital anoma
BACKGROUND: Kwashiorkor, a form of severe malnutrition with high mortality, is characterized by edema and systemic abnormalities. Although extremely common, its pathophysiology remains poorly understood, and its characteristic physical signs are unexplained.OBJECTIVE: Because kwashiorkor can develop in protein-losing enteropathy, which is caused by a loss of enterocyte heparan sulfate proteoglycan
"The COVID-19 pandemic has taught us the terrible cost of being unprepared for global health emergencies. The lack of treatments, vaccines, and sufficiently coordinated responses resulted in many unprecedented challenges that must now be analyzed and tackled rapidly. The crisis has raised awareness of the urgent need to improve the design of health systems, as well as the practical implementation
Background: Near-infrared spectroscopy (NIRS) and intravascular ultrasound are promising imaging modalities to identify non-obstructive plaques likely to cause coronary-related events. We aimed to assess whether combined NIRS and intravascular ultrasound can identify high-risk plaques and patients that are at risk for future major adverse cardiac events (MACEs). Methods: PROSPECT II is an investig
Background: Dysregulated complement activation, increased protein citrullination, and production of autoantibodies against citrullinated proteins are hallmarks of rheumatoid arthritis (RA). Citrullination is induced by immune cell-derived peptidyl-Arg deiminases (PADs), which are overactivated in the inflamed synovium. We characterized the effect of PAD2- and PAD4-induced citrullination on the abi
