BMD, clinical risk factors and their combination for hip fracture prevention

This study examined the effects of the use of clinical risk factors (CRFs) alone, BMD alone or the combination using the FRAXA (R) tool for the detection of women at risk of hip fracture. BMD tests alone selected women at higher risk and a greater number of hip fracture cases were identified compared to the use of CRFs alone. The combined use of CRFs and BMD identified fewer women above a threshol

Anti-HIV activity of the small modified amino acid {alpha}-hydroxy glycineamide on in vitro and in vivo HIV-1 capsid assembly and infectivity

Upon maturation of the HIV-1 virion, proteolytic cleavage of the Gag precursor protein by the viral protease is followed by morphological changes of the capsid protein p24 which will ultimately transform the virus core from an immature spherical to a mature conical structure. Virion infectivity is critically dependent on the just right semi-stability of the capsid cone structure. We have earlier r

Apoptosis and tumor cell death in response to HAMLET (human alpha-lactalbumin made lethal to tumor cells).

HAMLET (human alpha-lactalbumin made lethal to tumor cells) is a molecular complex derived from human milk that kills tumor cells by a process resembling programmed cell death. The complex consists of partially unfolded alpha-lactalbumin and oleic acid, and both the protein and the fatty acid are required for cell death. HAMLET has broad antitumor activity in vitro, and its therapeutic effect has

Potential Fit to the Department Outweighs Professional Criteria in the Hiring Process in Academic Libraries

Objective – To identify key factors affecting the probability of obtaining an interview and being hired for an academic library position. Design – An online survey was distributed via the following electronic mail lists: ACRL, LITA, COLLIB, METRO, ACQNET, COLLDV, ULS, EQUILIBR, and ALF. The questionnaire was posted via StudentVoice, an assessment survey provider. Setting – Academic libraries in

Regulation of the myogenic response and stretch-induced calcium signaling in the vascular wall: Novel insights into the role of microRNAs and protein tyrosine kinase 2

Intraluminal pressure has a significant impact on vascular adaptability, phenotype and regulation of blood flow and pressure. On one hand, increased pressure/stretch for a prolonged time can cause structural changes in vessel wall; on the other hand, lack of pressure/stretch can promote a phenotype shift. This thesis investigates novel roles of microRNAs and protein tyrosine kinase 2 in pressure/s

Testing the SF-36 in Parkinson's disease : Implications for reporting rating scale data.

Rating scales are increasingly the primary outcome measures in clinical trials. However, clinically meaningful interpretation of such outcomes requires that the scales used satisfy basic requirements (scaling assumptions) within the data. These are rarely tested. The SF-36 is the most widely used patient-reported rating scale. Its scaling assumptions have been challenged in neurological disorders

Characterization of fluid flow in a shear band in porous rock using neutron radiography

The challenge of understanding how localized deformation modifies fluid flow in porous rock is addressed. New approaches are presented, based on neutron radiography and digital image analyses, to track fluid flow in rock specimens and to calculate flow velocity fields providing local flow measurements. The results show that neutron radiography, backed up by appropriate image analysis, is a very po

Segmenting dynamic human action via statistical structure

Human social, cognitive, and linguistic functioning depends on skills for rapidly processing action. Identifying distinct acts within the dynamic motion flow is one basic component of action processing; for example, skill at segmenting action is foundational to action categorization, verb learning, and comprehension of novel action sequences. Yet little is currently known about mechanisms that may

Institutional trust and alcohol consumption in Sweden: The Swedish National Public Health Survey 2006

Background: Trust as a measure of social capital has been documented to be associated with health. Mediating factors for this association are not well investigated. Harmful alcohol consumption is believed to be one of the mediating factors. We hypothesized that low social capital defined as low institutional trust is associated with harmful alcohol consumption. Methods: Data from the 2006 Swedish

Bibliofil: a Tool that Facilitates Parallel Publishing

Since 2002, the Library & ICT Unit at the Faculty of Medicine, Lund University, has been assigned to support researchers in the scientific communication process at the faculty. One of the services offered to authors in this context is aimed at making their final products—articles that have been accepted, peer reviewed, and published by any journal—available through open access on the Internet.

Stroke, Sex and Vascular Receptor Changes in the Brain

Stroke is a severe cerebrovascular disease in which the neuronal tissue and vasculature of the brain undergo ischemia-evoked alterations. We have demonstrated an increased expression of cerebrovascular contractile receptors in the brain. This is hypothesized to mitigate cerebral blood flow and exacerbate tissue damage after stroke. An increased contractile property of these receptors has been demo

Growth of saprotrophic fungi and bacteria in soil.

Bacterial and fungal growth rate measurements are sensitive variables to detect changes in environmental conditions. However, while methods to assess the species composition and biomass of fungi and bacteria has made much progress, information about growth rates remains surprisingly rudimentary. We review the recent history of approaches to assess bacterial and fungal growth rates, leading up to c

A Typology of Narratives of Social Inclusion and Exclusion: The Case of Bankrupt Entrepreneurs

On the macro level, bankruptcies are an intrinsic part of market economies and result in restructurings of companies and markets. On the micro level, bankrupt entrepreneurs are temporarily excluded from the market and forced to reorganize their understanding of the market. While some seek their way back to entrepreneurship, others decide to find other means of living which may result in drainage o

Antibodies against gonadotropin-releasing hormone (GnRH) and destruction of enteric neurons in 3 patients suffering from gastrointestinal dysfunction

Background: Antibodies against gonadotropin-releasing hormone (GnRH) and gastrointestinal dysmotility have been found after treatment with GnRH analogues. The aim of this study was to examine the presence of such antibodies in patients with dysmotility not subjected to GnRH treatment and study the anti-GnRH antibody effect on enteric neurons viability in vitro. Methods: Plasma and sera from 3 pati

Implication of IL-2/IL-21 region in systemic sclerosis genetic susceptibility

Objective The interleukin 2 (IL-2) and interleukin 21 (IL-21) locus at chromosome 4q27 has been associated with several autoimmune diseases, and both genes are related to immune system functions. The aim of this study was to evaluate the role of the IL-2/IL-21 locus in systemic sclerosis (SSc). Patients and methods The case control study included 4493 SSc Caucasian patients and 5856 healthy contro

The presence of tumor associated macrophages in tumor stroma as a prognostic marker for breast cancer patients

Background: Tumor associated macrophages (TAMs) are alternatively activated macrophages that enhance tumor progression by promoting tumor cell invasion, migration and angiogenesis. TAMs have an anti-inflammatory function resembling M2 macrophages. CD163 is regarded as a highly specific monocyte/macrophage marker for M2 macrophages. In this study we evaluated the specificity of using the M2 macroph
