Activator protein-1 in carotid plaques is related to cerebrovascular symptoms and cholesteryl ester content.

INTRODUCTION: Transcription factor activator protein-1 regulates genes involved in inflammation and repair. The aim of this study was to determine whether transcription factor activator protein-1 activity in carotid plaques is related to symptoms, lipid accumulation, or extracellular matrix composition. METHODS: Twenty-eight atherosclerotic carotid plaques were removed by endarterectomy and divide

Societal Value of Stem Cell Therapy in Stroke - A Modeling Study.

Background: Stroke is one of the major causes of disability in the adult population and represents a heavy social and economic burden. Currently available therapeutic tools to support the recovery of impaired brain functions are quite limited. Animal studies have demonstrated that neuronal replacement and partial reconstruction of neural circuitry or modulation of the recovery process is possible

The views of physicians and politicians concerning age-related prioritisation in healthcare.

PURPOSE: The aim of this study is to describe the view of age-related prioritisation in health care among physicians and healthcare politicians and to compare their views regarding gender and age. DESIGN/METHODOLOGY/APPROACH: Swedish physicians (n=390) and politicians (n=310), mean age 52 years, answered an electronic questionnaire concerning age-related priority setting in healthcare. The questio

Static and dynamical effects of core holes in KLV Auger, SXE, and SXA spectra of simple metals

The authors examine the effect of the core hole on several spectroscopies used to explore the conduction band of simple metals. They show that the static effect on the valence electrons is very strong and discuss under what circumstances this effect may be seen experimentally. In KLV Auger spectra a core hole is present in both initial and final states. Thus, there will be almost no dynamical effe

Architectures and arithmetic for low static power consumption in nanoscale CMOS

This paper focuses on leakage reduction at architecture and arithmetic level. A methodology for considerable reduction of the static power consumption is shown. Simulations are done in a typical 130 nm CMOS technology. Based on the simulation results, the static power consumption is estimated and compared for different filter architectures. Substantial power reductions are shown in both FIR-filter

Regulation of the eicosanoid pathway by tumour necrosis factor alpha and leukotriene D(4) in intestinal epithelial cells.

In this study the mRNA and protein levels of the key enzymes involved in eicosanoid biosynthesis and the cysteinyl leukotriene receptors (CysLT(1)R and CysLT(2)R) have been analysed in non-transformed intestinal epithelial and colon cancer cell lines. Our results revealed that tumour necrosis factor alpha (TNF-alpha), and leukotriene D(4) (LTD(4)), which are inflammatory mediators implicated in ca

Decreasing Blood Pressure Over Time is the Strongest Predictor of Depressive Symptoms in Octogenarian Men.

OBJECTIVE: The aim of this study was to examine the longitudinal impact of blood pressure variations and vascular risk factors on depressive symptoms in the elderly. DESIGN: Longitudinal and cross-sectional cohort study. SETTING: Urban population of elderly men, city of Malmö, Sweden. PARTICIPANTS: A total of 809 randomly included men took part in a prospective cohort study, "Men born in 1914", an

Shaping discourses of multilingualism through a language ideological debate: The case of Swedish in Finland

The ideological (re)construction of the position of Swedish in Finland is examined as it took shape during a major year-long debate about the role of Swedish in Finnish education. Data were collected through archival research of the leading national newspapers in the two official languages of Finland: Helsingin Sanomat (Finnish) and Hufvudstadsbladet (Swedish). Circulating and intersecting discour

Observing strain localisation processes in bio-cemented sand using x-ray imaging

In-situ x-ray tomography has been used to follow deformation processes in 3D during two triaxial compression tests, one on a specimen of bio-cemented Ottawa 50-70 sand and the other on a specimen of the non-cemented sand. The global stress-strain responses show that the bio-cementation process increases the shear strength (peak deviator stress is approximately doubled), and causes the material to

Reduced CSF CART in dementia with Lewy bodies.

Dementia with Lewy bodies (DLB) is the second most common form of neurodegenerative dementia after Alzheimer's disease (AD). The underlying neurobiological mechanism of DLB is not fully understood and no generally accepted biomarkers are yet available for the diagnosis of DLB. In a recent MRI study, DLB patients displayed hypothalamic atrophy whereas this region was not affected in AD patients. Co

Diverse and Tissue Specific Mitochondrial Respiratory Response in A Mouse Model of Sepsis-Induced Multiple Organ Failure.

Mitochondrial function is thought to play a role in sepsis-induced multiple organ failure. However, the temporal and organ specific alterations in mitochondrial function has yet to be fully elucidated. Many studies show reduced phosphorylating capacity while others have indicated that mitochondrial respiration is enhanced. The objective of the study was to evaluate the temporal dynamics of brain a

Generation of attosecond pulses in macroscopic media

We describe theoretically the generation of ultrashort (subfemtosecond) pulses using high-order harmonics of a laser pulse with a time-dependent degree of ellipticity. The single-atom response is calculated by using a low-frequency strong-field approximation. Propagation effects are taken into account using a method going beyond the slowly varying envelope approximation. Propagation modifies signi

Risk factors for a contralateral anterior cruciate ligament injury.

Contralateral anterior cruciate ligament (ACL) injuries are together with the risk of developing osteoarthritis of the knee and the risk of re-rupture/graft failure important aspects to consider after an ACL injury. The aim of this review was to perform a critical analysis of the literature on the risk factors associated with a contralateral ACL injury. A better understanding of these risk factors

Adjuvant tamoxifen in breast cancer patients affects the endometrium by time, an effect remaining years after end of treatment and results in an increased frequency of endometrial carcinoma.

Tamoxifen is the most used adjuvant drug in breast cancer treatment. Its main action is as an anti-oestrogen, but in the endometrium of some patients it acts as an oestrogen. Some investigators have even reported an increased risk of developing endometrial carcinoma. The question of how to follow-up these patients and how to identify patients at risk of developing endometrial premalignant changes

Two new species of Caloplaca from Tadjikistan, Central Asia

Two new species of Caloplaca are described, C. pseudocitrina (in the C. citrina group), which is characterized by rather long spores with a thin septum, and a squamulose thallus and C. akbarica (C. saxicola-group) characterized by rather thick, brightly yellowish pruinose apothecia and a paraplectenchymatous proper exciple. The characters of the new species and their closely allied taxa are compar

Endoplasmic reticulum dynamics in hippocampal dendritic spines induced by agonists of type I metabotropic glutamate but not by muscarinic acetylcholine receptors.

Neurons in the hippocampus exhibit subpopulations of dendritic spines that contain endoplasmic reticulum (ER). ER in spines is important for synaptic activity and its associated Ca(2+) signaling. The dynamic distribution of ER to spines is regulated by diacylglycerol and partly mediated by protein kinase C, metalloproteinases and γ-secretase. In this study, we explored whether pharmacological acti

Does social capital protect mental health among migrants in Sweden?

Poor mental health is common among migrants. This has been explained by migration-related and socio-economic factors. Weak social capital has also been related to poor mental health. Few studies have explored factors that protect mental health of migrants in the post-migration phase. Such knowledge could be useful for health promotion purposes. Therefore, this study aimed to analyse associations b
