Fabrication of a highly efficient solid state electrochemiluminescence sensor using Ru(bpy)(3)(2+) incorporated nanoZnO-MWCNTs-Nafion composite film

A highly sensitive and stable solid state electrochemiluminescence (ECL) sensor for tri-n-propylamine (TPrA, as coreactant) detection was developed using Ru(bpy)(3)(2+) ion-exchanged into the composite film of ZnO nanoparticles decorated multi-walled carbon nanotubes (nanoZnO-MWCNTs) and Nafion. The electrocatalytic activity of nano-ZnO active sites towards Ru(bpy)(3)(2+) redox reaction and also t

Binding of complement inhibitor C4b-binding protein to a highly virulent S. pyogenes M1 strain is mediated by protein H and enhances adhesion to and invasion of endothelial cells.

Streptococcus pyogenes AP1, a strain of the highly virulent M1 serotype, uses exclusively protein H to bind the complement inhibitor C4b-binding protein (C4BP). We found a strong correlation between the ability of AP1 and its isogenic mutants lacking protein H to inhibit opsonisation with complement C3b and binding of C4BP. C4BP bound to immobilized protein H or AP1 bacteria retained its cofactor

Varicocele repair in non-obstructive azoospermic men: diagnostic value of testicular biopsy - A meta-analysis.

Abstract Azoospermia is observed in 10-15% of infertile men and 60% of these cases are classified as having non-obstructive azoospermia (NOA). NOA results from testicular failure, and one of the causes of this is the presence of varicocele. Varicocele is found in 5-10% of men with NOA and its repair is associated with the appearance of spermatozoa in the ejaculate in 21-55% of cases. This review d

A novel SERPINE1-FOSB fusion gene results in transcriptional up-regulation of FOSB in pseudomyogenic haemangioendothelioma.

Pseudomyogenic haemangioendothelioma (PHE) is an intermediate malignant vascular soft tissue tumour primarily affecting children and young adults. The molecular basis of this neoplasm is unknown. We here used chromosome banding analysis, fluorescence in situ hybridization (FISH), mRNA sequencing, RT-PCR and quantitative real-time PCR on a series of morphologically well-characterized PHEs to show t

The effects of spatial and temporal ecological variation on fatty acid compositions of wild great tits Parus major

In birds, fatty acids (FA) have three main functions; they are structural components of cell membranes, metabolic fuel, and inflammatory molecules. Environmental factors, such as diet and ambient temperature, affect FA composition, thereby function and ultimately fitness. Thus, variation in FA compositions can be the underlying mechanism for varying performance of birds in different habitats. Here

Automated determination of fibrillar structures by simultaneous model building and fiber diffraction refinement.

For highly oriented fibrillar molecules, three-dimensional structures can often be determined from X-ray fiber diffraction data. However, because of limited information content, structure determination and validation can be challenging. We demonstrate that automated structure determination of protein fibers can be achieved by guiding the building of macromolecular models with fiber diffraction dat

International Myeloma Working Group Recommendations for the Treatment of Multiple Myeloma-Related Bone Disease.

PURPOSEThe aim of the International Myeloma Working Group was to develop practice recommendations for the management of multiple myeloma (MM) -related bone disease.MethodologyAn interdisciplinary panel of clinical experts on MM and myeloma bone disease developed recommendations based on published data through August 2012. Expert consensus was used to propose additional recommendations in situation

Ischemia/reperfusion in rat: Antioxidative effects of enoant on EEG, oxidative stress and inflammation

Primary objective: The present study was undertaken to evaluate whether enoant, which is rich in polyphenols, has any effect on electroencephalogram (EEG), oxidative stress and inflammation in ischemia/reperfusion (I/R) injury. Methods: Ischemia was induced by 2-hour occlusion of bilateral common carotid artery. Animals orally received enoant. Group 1 was the ischemic control group. Group 2 was tr

Search for a heavy top-quark partner in final states with two leptons with the ATLAS detector at the LHC

The results of a search for direct pair production of heavy top-quark partners in 4.7 fb(-1) of integrated luminosity from p p collisions at root s = 7 TeV collected by the ATLAS detector at the LHC are reported. Heavy top-quark partners decaying into a top quark and a neutral non-interacting particle are searched for in events with two leptons in the final state. No excess above the Standard Mode

Outcomes of women with gestational diabetes mellitus in Sweden.

The number of women with gestational diabetes mellitus (GDM) during pregnancy is increasing around the world and in our region in the south Sweden 1.2% of all pregnant women received the GDM diagnosis in the 90s and now it is about 2.2%. The aim of this study was to compare women with GDM 1995-99 against women with GDM 2012-13 regarding eventual differences in demographics and pregnancy outcome.

Electrical properties of InAs1-xSbx and InSb nanowires grown by molecular beam epitaxy

Results of electrical characterization of Au nucleated InAs1-xSbx nanowires grown by molecular beam epitaxy are reported. An almost doubling of the extracted field effect mobility compared to reference InAs nanowires is observed for a Sb content of x = 0.13. Pure InSb nanowires on the other hand show considerably lower, and strongly diameter dependent, mobility values. Finally, InAs of wurtzite cr

Mitochondrial respiration in human viable platelets-Methodology and influence of gender, age and storage.

Studying whole cell preparations with intact mitochondria and respiratory complexes has a clear benefit compared to isolated or disrupted mitochondria due to the dynamic interplay between mitochondria and other cellular compartments. Platelet mitochondria have a potential to serve as a source of human viable mitochondria when studying mitochondrial physiology and pathogenic mechanisms, as well as

Express yourself: bold individuals induce enhanced morphological defences.

Organisms display an impressive array of defence strategies in nature. Inducible defences (changes in morphology and/or behaviour within a prey's lifetime) allow prey to decrease vulnerability to predators and avoid unnecessary costs of expression. Many studies report considerable interindividual variation in the degree to which inducible defences are expressed, yet what underlies this variation i

Molecular microheterogeneity of prostate specific antigen in seminal fluid by mass spectrometry.

OBJECTIVES: Prostate specific antigen (PSA) is a widely used and clinically valuable marker for prostate disease. In order to enable the development of new PSA assays and progress the understanding of the biology of PSA we have analyzed PSA in seminal plasma. Design and methods PSA in seminal plasma from men attending a fertility clinic and healthy controls was analyzed using SDS-PAGE, Western blo

Atherosclerosis aggravates ischemia/reperfusion injury in the gut and remote damage in the liver and the lung

Objective We investigated whether mesenteric ischemia/reperfusion (I/R)-associated gut injury and remote liver and lung damage are affected by prevalent atherosclerosis. Methods Mesenteric ischemia was induced in atherosclerotic ApoE-deficient (ApoE(-/-)) and control C57BL/6 mice by clamping the superior mesenteric artery for 30 min. Mesenteric microcirculatory dysfunction and leukocytic inflammat
