Telomeres, the chromatin structures at the ends of eukaryotic chromosomes, are essential for chromosome stability. The telomere terminates with a TG-rich 3' overhang, which is bound by sequence-specific proteins that both protect the end and regulate the telomerase elongation process. Here, we demonstrate the presence of 3' overhangs as long as 200 nt in asynchronously growing cells of the budding
We have investigated the magnetoresistance (MR) in a series of Zn doped (p-type) GaAs nanowires implanted with different Mn concentrations. The nanowires with the lowest Mn concentration (similar to 0.0001%) exhibit a low resistance of a few k Omega at 300 K and a 4% positive MR at 1.6 K, which can be well described by invoking a spin-split subband model. In contrast, nanowires with the highest Mn
Dental implant abutments that emerge through the mucosa are rapidly covered with a salivary protein pellicle to which bacteria bind, initiating biofilm formation. In this study, adherence of early colonizing streptococci, Streptococcus gordonii, Streptococcus oralis, Streptococcus mitis and Streptococcus sanguinis to two saliva-coated anodically oxidized surfaces was compared with that on commerci
Acquired genetic aberrations are the underlying cause of leukemogenesis in acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL). The karyotypes of AML and ALL cases are generally quite simple as seen by chromosome banding analysis, with few genetic changes and a limited number of subclones. However, investigations using fluorescence in situ hybridization, loss of heterozygosity anal
Abstract Background and aims. Collagenous colitis (CC) is associated with autoimmune disorders. The aim of the present study was to investigate the relationship between CC and autoimmune disorders in a Swedish multicenter study. Methods. Patients with CC answered questionnaires about demographic data and disease activity. The patient's files were scrutinized for information about autoimmune diseas
The design thinking concept emphasizes the actual activity of solving problems with a design approach, associating it to the designer's knowledge and competence instead of the intimate link between design and the physical object. Yet design consultancies still have problems charging for intangible components in their offerings and for the role of strategic consultants. We argue that the design thi
Epidemiological data regarding tea and coffee consumption and risk of esophageal cancer (EC) is still inconclusive. We examined the association of tea and coffee consumption with EC risk among 442,143 men and women without cancer at baseline from 9 countries of the European Prospective Investigation into Cancer and Nutrition. Tea and coffee intakes were recorded using country-specific validated di
Purpose: Plasma apolipoprotein M (apoM) is potentially anti-atherogenic, and has been found to be associated positively with plasma total, LDL and HDL cholesterol in humans. ApoM may, therefore, be intricately related to cholesterol metabolism. Here, we determined whether plasma apoM is affected by statin or fibrate administration in patients with diabetes mellitus. Methods: Fourteen type 2 diabet
In this retrospective, Dr. Lars Edvinsson recounts early steps and milestones in our understanding of the neuropeptide calcitonin gene-related peptide (CGRP) in the trigeminovascular system and its role in migraine. The discovery of the presence and function of CGRP and other neuropeptides in the cerebral vasculature and its sensory innervation is described. He relates the seminal finding that CGR
Galiellalactone (GL) is a metabolite produced by the fungus Galiella rufa that presents antitumor and immunomodulatory activities. GL interferes with the binding to DNA of signal transducer and activator of transcription (STAT)-3 and also inhibits other signal pathways such as NF-κB, but the mechanism of action in this pathway remains unknown. In this study we report that GL inhibits vesicular sto
Purpose – This paper aims to analyze the conditions for co-creation in a non-commercial context. The particular aim is to show how a co-creative activity is framed for the participants and the consequences of the frames for the values that are co-created in the process. Design/methodology/approach – Goffman’s frame analysis is applied to investigate how co-creation is used as a marketing strategy
This report contains the mature five-year data from the Swedish ARTSCAN trial including information on the influence of p16 positivity (p16+) for oropharyngeal cancers.
Background In randomized controlled trials of secondary prevention after stroke, the risk of hemorrhage varies between 1% and 5% per year in patients with antithrombotic therapy, i.e. anticoagulants and antiplatelets. Aim To explore the rate and the risk of hemorrhage after stroke in a nationwide cohort. Methods We identified 58 868 first ever ischemic stroke patients in the Swedish Stroke Registe
The growth and optoelectronic properties of core-shell nanostructures are influenced by the strain induced by the lattice mismatch between core and shell. In contrast with planar films, nanostructures contain multiple facets that act as independent substrates for shell growth, which enables different relaxation mechanisms. In this study, X-ray diffraction data are presented that show that InGa1-N
Colonic fermentation of dietary fiber produces carboxylic acids and may stimulate the growth of beneficial bacteria. This study investigated how byproducts of wheat processing (distillers' grains and two fractions from the wet fractionation to starch and gluten, one of which was treated with xylanase) affect the composition of the cecal microbiota and the formation of carboxylic acids in rats. Dif
The frequency of obesity has risen dramatically in recent years but only few effective and safe drugs are available. We investigated if green-plant membranes, previously shown to reduce subjective hunger and promote satiety signals, could affect body weight when given long-term. 38 women (40-65 years of age, body mass index 25-33 kg/m(2)) were randomized to dietary supplementation with either gree
Genetic screening has been defined as any kind of test performed systematically for the early detection or exclusion of a genetic disease, genetic predisposition or resistance to a disease, or to determine whether a person carries a gene variant that may produce disease in his or her offspring. In comparison to 'genetic testing', the term 'genetic screening' should be reserved for the explicit and
Purpose: To investigate factors associated with bilateral glaucoma blindness, particularly factors available at the time of diagnosis. Methods: Retrospective chart review of all patients with primary open-angle glaucoma (POAG) or pseudoexfoliative glaucoma (PEXG) followed at the Department of Ophthalmology or Low Vision Center of Skåne University Hospital, Malmö, Sweden, who died between January 2
Colorectal cancer (CRC) is the third most common malignant tumor and the fourth leading cause of cancer death worldwide. The crucial role of fatty acids for a number of important biological processes suggests a more in-depth analysis of inter-individual differences in fatty acid metabolizing genes as contributing factor to colon carcinogenesis. We examined the association between genetic variabili
