Blood-brain barrier permeability and nerve cell damage in rat brain 14 and 28 days after exposure to microwaves from GSM mobile phones.
We investigated the effects of global system for mobile communication (GSM) microwave exposure on the permeability of the blood-brain barrier and signs of neuronal damage in rats using a real GSM programmable mobile phone in the 900 MHz band. Ninety-six non-anaesthetized rats were either exposed to microwaves or sham exposed in TEM-cells for 2 h at specific absorption rates of average whole-body S
P2 receptors in cardiovascular regulation and disease.
The role of ATP as an extracellular signalling molecule is now well established and evidence is accumulating that ATP and other nucleotides (ADP, UTP and UDP) play important roles in cardiovascular physiology and pathophysiology, acting via P2X (ion channel) and P2Y (G protein-coupled) receptors. In this article we consider the dual role of ATP in regulation of vascular tone, released as a cotrans
Antibiotic prophylaxis in urological surgery, a European viewpoint.
Surgical site infections (SSI) including urinary tract infections (UTI) cause a significant morbidity in urological surgery. Antibiotic prophylaxis is one of several factors impacting on infection rates. Antibiotic prophylaxis is relevant only for clean and clean-contaminated operations and in the absence of bacterial growth in the urine. Strict classification of urological procedures is lacking,

Ubiquitin chain cleavage: CYLD at work.
The tumor suppressor CYLD is a deubiquitylating enzyme that negatively regulates different signaling pathways by removing lysine 63-linked polyubiquitin chains from several specific substrates. In various tumor types, CYLD loss can lead to cell survival or cell proliferation. In addition to its loss due to mutations, CYLD expression can also be decreased through transcriptional and post-transcript
Dermatan Sulfate Epimerase 1-Deficient Mice have Reduced Content and Changed Distribution of Iduronic acids in Dermatan Sulfate and an Altered Collagen Structure in Skin.
Dermatan sulfate epimerase 1 (DS-epi1) and 2 convert glucuronic acid to iduronic acid in chondroitin/dermatan sulfate biosynthesis. Here we report on the generation of DS-epi1-null mice and the resulting alterations in the chondroitin/dermatan polysaccharide chains. The numbers of long blocks of adjacent iduronic acids are greatly decreased in skin decorin and biglycan chondroitin/dermatan sulfate
Reducing delirium in elderly patients with hip fracture: a multi-factorial intervention study.
Background: There is an evident need for improved management of elderly patients with trauma in order to avoid common and troublesome complications such as delirium. The aim of this study was to investigate whether an implementation of a multi-factorial program including intensified pre-hospital and perioperative treatment and care could reduce the incidence of delirium in elderly patients with hi
Establishing a Diagnosis in Indeterminate Pancreaticobiliary Strictures: Is Confocal Laser Endomicroscopy the Answer?
The Short-Term Results of 3 Common UKA Implants During Different Periods in Sweden.
We studied 13299 operations of 3 common unicompartmental implants inserted during 1984 to 2004 and compared their cumulative revision rate during different periods, as well as whether minimally invasive surgery (MIS) had been used. In this way, we tried to evaluate how the introduction of implants and approaches affected the short-term results. The oldest implant, the Link, had stable results over
CYP2C8 and CYP2C9 polymorphisms in relation to tumour characteristics and early breast cancer related events among 652 breast cancer patients.
BACKGROUND: CYP2C8/9 polymorphisms may influence breast cancer-free survival after diagnosis due to their role in the metabolism of tamoxifen, paclitaxel, and other chemotherapy. cytochrome P450 (CYP)2C8/9 metabolise arachidonic acid to epoxyeicosatrienoic acids, which enhance migration and invasion in vitro and promote angiogenesis in vivo. We aimed to investigate the frequency of CYP2C8/9 polymo
Antibodies Against Deamidated Gliadin Peptides and Tissue Transglutaminase for Diagnosis of Pediatric Celiac Disease - Diagnostic Performance and Cost in Clinical Practice.
OBJECTIVES: To evaluate diagnostic performance and actual costs in clinical practice of IgG/IgA deamidated gliadin peptide antibodies (DGP) as a complement to IgA antibodies against tissue transglutaminase (tTG) for the diagnosis of pediatric celiac disease (CD). PATIENTS AND METHODS: All consecutive patients
Prevention and prediction of inhibitor risk.
Summary: Studies of determinants of the development of inhibitory antibodies in patients with haemophilia indicate that this is a complex process involving several factors. The foundation is characterized by the T- and B-cell repertoire and the antigen presenting cells and to elicit an immune response to the deficient factor, a pre-disposing foundation is needed. Hence, in the absence of a certain
Expression and role of FLT3 in regulation of the earliest stage of normal granulocyte-monocyte progenitor development.
Mice deficient in FLT3 signalling have reductions in early multipotent and lymphoid progenitors, whereas no evident myeloid phenotype has been reported. However, activating mutations of Flt3 are among the most common genetic events in acute myeloid leukemia and mice harbouring internal tandem duplications within Flt3 (Flt3-ITD) develop myeloproliferative disease, with characteristic expansion of g

Determination of Radiative Lifetimes of Neutral Bismuth By Time-resolved Uv-vuv Laser Spectroscopy
Time-resolved laser spectroscopy was used to measure natural radiative lifetimes of ten excited states of neutral bismuth. Four levels of the 6p(2)ns (4)p(1/2) sequence (n = 7,8,9,10) and the 6p(2)7s P-4(3/2),(5/2) and 6p(2)nd(2)D(2/3;5/2) (n = 6,7) levels were investigated. The results are compared with previous data when possible. Revised absolute transition probabilities for 26 lines are given.
Quantifying the optical properties and chromophore concentrations of turbid media by chemometric analysis of hyperspectral diffuse reflectance data collected using a fourier interferometric imaging system
A non-contact Fourier transform interferometric imaging system was used to collect hyperspectral images of the steady-state diffuse reflectance from a point source in turbid media for the spectral range of 550-850 nm. Steady-state diffuse reflectance profiles were generated from the hyperspectral images, and partial least-squares (PLS) regression was performed on the diffuse reflectance profiles t
The evaluation of an electrocardiographic myocardial ischemia acuteness score to predict the amount of myocardial salvage achieved by early percutaneous coronary intervention Clinical validation with myocardial perfusion single photon emission computed tomography and cardiac magnetic resonance.
BACKGROUND: The time from symptom onset to reperfusion in acute myocardial infarction (MI) has been shown to be a poor predictor of patient outcome. Acute electrocardiographic (ECG) changes, however, have been shown useful for estimated acuteness of myocardial ischemia using the Anderson-Wilkins ECG ischemia acuteness score (AW-acuteness score). The aim was to study whether acute ischemic ECG chan
EU Climate Action in the Broad Framework of Sustainable Development Policies
The linkages between climate change and sustainable development are multiple and profound. Nonetheless, their respective policy regimes have so far evolved along parallel, if not competing, paths. What is lacking to date is a detailed conceptual understanding of the practicability of their integration through cross-sectoral policies and programmes. We propose a synergistic adaptive capacity (SAC)
