Evidence on the association between dietary flavonoids and lignans and breast cancer (BC) risk is inconclusive, with the possible exception of isoflavones in Asian countries. Therefore, we investigated prospectively dietary total and subclasses of flavonoid and lignan intake and BC risk according to menopause and hormonal receptor status in the European Prospective Investigation into Cancer and Nu

Protein molecules are responsible for many biological functions in cells. In order to fulfill their various biological roles, these chain-like molecules must fold into precise three-dimensional shapes. The knowledge of accurate molecular structures is a prerequisite for rational drug design and for structure based functional studies. Getting structural information of proteins can be a very difficu

The process of population ageing that has been occurring in Sweden can be expected to continue during the coming decades, the population pyramid will become increasingly rectangular, and possibly even demonstrating a shrinking base. This will lead to increasing challenges in terms of financing pensions, elderly care and healtcare. These problems will continue for at least 30 years with no demograp

Popular Abstract in English Blood, a deep red fluid, circulates in vessels throughout our body. It consists of two main components, a liquid part and a cell part. The liquid portion, which is also called ‘plasma’, takes a main function in transporting water, nutrients, and immune substances. The cell components, which are suspended in the plasma, consist of three main cell types including platelet

BackgroundPast research has identified aortic stenosis (AS) as a major risk factor for adverse outcomes in noncardiac surgery; however, more contemporary studies have questioned the grave prognosis. To further our understanding of this, the risks of a 30-day major adverse cardiovascular event (MACE) and all-cause mortality were investigated in a contemporary Danish cohort. HypothesisAS is not an i

Objective-Atherosclerosis is an inflammatory disease. Autoimmune responses to low-density lipoproteins (LDL) contribute to its progression, whereas immunization with LDL may induce atheroprotective or proatherogenic responses. The objective of this study was to develop an atheroprotective vaccine by targeting a peptide of the LDL protein constituent apolipoprotein B-100 (apoB-100) to the nasal muc

A plethora of peptides are generated intracellularly, and most peptide-human leukocyte antigen (HLA)-I interactions are of a transient, unproductive nature. Without a quality control mechanism, the HLA-I system would be stressed by futile attempts to present peptides not sufficient for the stable peptide-HLA-I complex formation required for long term presentation. Tapasin is thought to be central

OBJECTIVE: To study patient reported physical activity in patients with spondyloarthritis (SpA) and possible differences in physical activity patterns between the SpA subtypes and genders. METHODS: In 2009 a questionnaire including questions concerning physical activity was sent to patients with a SpA diagnosis (n=3711). The WHO "Global recommendations of physical activity for health" requirin

Engineered nanoparticles have been under increasing scrutiny in recent years. High aspect ratio nanoparticles such as carbon nanotubes and nanowires have raised safety concerns due to their geometrical similarity to asbestos fibers. III-V epitaxial semiconductor nanowires are expected to be utilized in devices such as LEDs and solar cells and will thus be available to the public. In addition, clea

To resist infections, robust defense mechanisms of the airways are essential. Retinoic acid promotes differentiation and maintains the phenotypic characteristics of bronchial epithelium. In addition, it induces the expression of the antibacterial growth factor midkine (MK). In the present study, we explored the expression and antibacterial activity of MK in an airway context. MK was detected in br

Studies on the influence of alcohol consumption on lung function have shown conflicting results. Self-reported alcohol consumption may be inaccurate. This study used both a validated alcohol questionnaire and a blood marker of heavy alcohol consumption, and examined potential associations with different lung physiological variables.

In jawed vertebrates, development of an adaptive immune-system is essential for protection of the born organism against otherwise life-threatening pathogens. Myeloid cells of the innate immune system are formed early in development, whereas lymphopoiesis has been suggested to initiate much later, following emergence of definitive hematopoietic stem cells (HSCs). Herein, we demonstrate that the emb

Dietary fats could affect glucose metabolism and obesity development and, thereby, may have a crucial role in the cause of type 2 diabetes (T2D). Studies indicated that replacing saturated with unsaturated fats might be favorable, and plant foods might be a better choice than animal foods. Nevertheless, epidemiologic studies suggested that dairy foods are protective.

Introduction: Inherited deficiencies of several complement components strongly predispose to systemic lupus erythematosus (SLE) while deficiencies of complement inhibitors are found in kidney diseases such as atypical hemolytic uremic syndrome (aHUS). Methods: The exons of complement inhibitor genes CD46 and CFH (factor H) were fully sequenced using the Sanger method in SLE patients with nephritis

Sensitive and non-intrusive detection of gas-phase methanol with high spatial and temporal resolution has for the first time been reported using mid-infrared degenerate four-wave mixing (IR-DFWM). IR-DFWM spectra of methanol have been successfully recorded in nitrogen-diluted gas flows at room temperature and at 300 A degrees C, by probing ro-vibrational transitions belonging to the fundamental C-
