Heterozygosity for a coding SNP in COL1A2 confers a lower BMD and an increased stroke risk

Genetic variation plays ail important role in osteoporosis and a prime candidate gene is Collagen alpha2(I) (COL1A2). A coding polymorphism (rs42524) in COL1A2 has previously been associated with intracranial aneurysms. Here the effects of this polymorphism have been Studied in relation to bone mineral density (BMD) and prevalences of stroke and myocardial infarction (MI). rs42524 was genotyped in

HIF2α contributes to antiestrogen resistance via positive bilateral crosstalk with EGFR in breast cancer cells.

The majority of breast cancers express estrogen receptor α (ERα), and most patients with ERα-positive breast cancer benefit from antiestrogen therapy. The ERα-modulator tamoxifen and ERα-downregulator fulvestrant are commonly employed antiestrogens. Antiestrogen resistance remains a clinical challenge, with few effective treatments available for patients with antiestrogen-resistant breast cancer.

Property-close source separation of hazardous waste and waste electrical and electronic equipment - A Swedish case study.

Through an agreement with EEE producers, Swedish municipalities are responsible for collection of hazardous waste and waste electrical and electronic equipment (WEEE). In most Swedish municipalities, collection of these waste fractions is concentrated to waste recycling centres where households can source-separate and deposit hazardous waste and WEEE free of charge. However, the centres are often

Ethnic differences in breast cancer risk and survival: A study on immigrants in Sweden

Background. There are large geographic differences in breast cancer risk but whether survival differs between low- and high-risk groups is less well-established. As the survival of cancer depends on the level of healthcare and awareness of disease risks, subtle differences in cancer biology cannot be revealed in international comparisons. Instead, comparison of diverse immigrant groups in a countr

Structural dynamics teaching example: A linear test analysis case using open software

Teaching the topic of structural dynamics in any engineering field is a true challenge due to the wide span of the underlying subjects like mathematics, mechanics (both rigid body and continuum mechanics), numerical analysis, random data analysis and physical understanding.With the increased availability of computers many engineering problems in practice are evaluated by means of numerical methods

A moth pheromone brewery: production of (Z)-11-hexadecenol by heterologous co-expression of two biosynthetic genes from a noctuid moth in a yeast cell factory

Background: Moths (Lepidoptera) are highly dependent on chemical communication to find a mate. Compared to conventional unselective insecticides, synthetic pheromones have successfully served to lure male moths as a specific and environmentally friendly way to control important pest species. However, the chemical synthesis and purification of the sex pheromone components in large amounts is a diff

Two new types of assays to determine protein concentrations in biological fluids using mass spectrometry of intact proteins with cystatin C in spinal fluid as an example

There is no reference method that is generally acknowledged to be unbiased for the determination of the concentration of any protein in biological fluids. This is probably because mass spectrometry (MS) methods acknowledged as reference methods for determination of low molecular mass substances in biological fluids, e.g. creatinine, have been difficult to adapt for proteins. Here we suggest two te

One-step purification of recombinant human amelogenin and use of amelogenin as a fusion partner.

Amelogenin is an extracellular protein first identified as a matrix component important for formation of dental enamel during tooth development. Lately, amelogenin has also been found to have positive effects on clinical important areas, such as treatment of periodontal defects, wound healing, and bone regeneration. Here we present a simple method for purification of recombinant human amelogenin e

Hereditary risk factors for stroke in humans - Association studies with emphasis on familial and genotypic factors

Popular Abstract in Swedish Stroke, eller slaganfall, är en sammanfattande benämning på sjukdomar som drabbar blodförsörjningen i hjärnan. Varje år insjuknar cirka 30000 personer i Sverige i stroke, av dessa drabbas cirka 15% av blödningar medan resterande 85% får infarkter, dvs blodpropp i hjärnan. Stroke upptar fler vårddagar i slutenvården än någon annan somatisk sjukdom. Medianåldern för insjuBackground Stroke is a serious vascular disorder that comprises intracerebral hemorrhages, subarachnoid hemorrhages and ischemic stroke (IS). The etiology of stroke, including hereditary components induced by cellular mechanisms, is therefore a research field of vital importance. The aim of this thesis was to assess possible genetic impact on stroke risk. We thus evaluated family history of strok

Palladium versus Platinum: The Metal in the Catalytic Center of a Molecular Photocatalyst Determines the Mechanism of the Hydrogen Production with Visible Light

To develop highly efficient molecular photocatalysts for visible light-driven hydrogen production, a thorough understanding of the photophysical and chemical processes in the photocatalyst is of vital importance. In this context, in situ X-ray absorption spectroscopic (XAS) investigations show that the nature of the catalytically active metal center in a (N boolean AND N)MCl2 (M=Pd or Pt) coordina

CLEFT LIP AND PALATE. CLINICAL STUDIES REGARDING SPEECH AND FACIAL GROWTH

Cleft lip and palate (CLP), the most common of all craniofacial anomalies, has an incidence about 2 per 1000 births in the Scandinavian countries. The Department of Plastic and Reconstructive Surgery in Malmö has been a regional centre in southern Sweden for the treatment of patients with CLP since 1954 with about 40 new cases of clefts each year. Speech and facial growth are important objectives

Frontiers in growth and remodeling

Unlike common engineering materials, living matter can autonomously respond to environmental changes. Living structures can grow stronger, weaker, larger, or smaller within months, weeks, or days as a result of a continuous microstructural turnover and renewal. Hard tissues can adapt by increasing their density and grow strong. Soft tissues can adapt by increasing their volume and grow large. For

Recreational football training decreases risk factors for bone fractures in untrained premenopausal women

The present intervention was designed to investigate whether a 14-week period of regular recreational association football (F) or endurance running (R) has an effect on the risk of falls and bone fractures due to gains in muscle function and volumetric bone mineral density (vBMD). Fifty healthy untrained Danish premenopausal women were randomized into two training groups (F and R) that trained 1.8

TAP1-Deficiency Does Not Alter Atherosclerosis Development in Apoe(-/-) Mice.

Antigen presenting cells (APC) have the ability to present both extra-cellular and intra-cellular antigens via MHC class I molecules to CD8(+) T cells. The cross presentation of extra-cellular antigens is reduced in mice with deficient Antigen Peptide Transporter 1 (TAP1)-dependent MHC class I antigen presentation, and these mice are characterized by a diminished CD8(+) T cell population. We have
