Photoluminescence (PL) of organo-metal halide perovskite semiconductors can be enhanced by several orders of magnitude by exposure to visible light. We applied PL microscopy and super-resolution optical imaging to investigate this phenomenon with spatial resolution better than 10 nm using films of CH3NH3PbI3 prepared by the equimolar solution-deposition method, resulting in crystals of different s

Human immunodeficiency virus type-2 (HIV-2) infected individuals develop immunodeficiency with a considerable delay and transmit the virus at a lower rate as compared to HIV-1 infected. Conceivably, comparative studies on immune responsiveness of the HIV-1 and HIV-2 infected hosts may help to explain differences in pathogenesis and transmission between the two types of infection. Previous studies

Although advances in cardiopulmonary resuscitation have improved survival from cardiac arrest (CA), neurologic injury persists and impaired mitochondrial bioenergetics may be critical for targeted neuroresuscitation. The authors sought to determine if excellent cardiopulmonary resuscitation and postresuscitation care and good traditional survival rates result in persistently disordered cerebral mi

Myelodysplastic syndromes (MDSs) are a group of hematopoietic stem cell disorders characterized by ineffective hernatopoiesis and peripheral blood cytopenias. Lenalidomide has dramatic therapeutic effects in patients with low-risk MDS and a chromosome 5q31 deletion, resulting in complete cytogenetic remission in >60% of patients. The molecular basis of this remarkable drug response is unknown. To

An outbreak of gastroenteritis affecting 158 of 219 (72%) guests and employees at a hotel is described. Food served at the hotel restaurant is believed to have been the source of the outbreak and to have been contaminated by sick employees working in the restaurant. A secondary attack rate of 22% was seen involving 43 persons in all. In stool specimens from seven of eight patients, Norwalk-like vi

Popular Abstract in Swedish Varje år insjuknar mer än 8000 kvinnor i Sverige i bröstcancer, och 5 år efter diagnos är nära 90% fortfarande i livet. Trots att prognosen för majoriteten av patienterna är god, dör 1400 kvinnor årligen av bröstcancer. Till följd av detta pågår mycket forskningsarbete för att finna faktorer som bättre kan förutsäga prognos, prognostiska studier, men även för att finna Breast cancer is the most common tumour form and the second leading cause of death in solid tumours in women in the Western world. Despite improvements in the treatment, a considerable number of patients will relapse and die from their breast cancer. At the same time, a substantial number of patients will be over-treated, as they would have been cured by surgery and radiotherapy alone. In the meta

Mary Flannery O’Connor (1925-64) was born in Savannah, Georgia as the only child of the American Irish Catholics Edward Francis O’Connor, Jr. and Regina Cline O’Connor. In 1952 her first novel Wise Blood, in 1955 the short story collection A Good Man Is Hard to Find, and in 1960 her second novel, The Violent Bear It Away were published. She received several fellowships and titles of Honorary Docto

Neisseria meningitidis lipopolysaccharide (LPS) has been identified as a major determinant of dendritic cell (DC) function. Here we report that one of a series of meningococcal mutants with defined truncations in the lacto-N-neotetraose outer core of the LPS exhibited unique strong adhesion and internalization properties towards DC. These properties were mediated by interaction of the GlcNAc(beta1

The advent of multiplexing technologies has raised the possibility that disease states can be defined using discrete genomic and proteomic patterns or signatures. However this emerging area has been limited by the 'content problem', arising from the uncertainty of which molecules to focus on. The human cluster of differentiation (CD) antigens are expressed on cells of the human immune system (leuk

BACKGROUND: The purpose of this study was to analyze the impact of stent-graft design and operator skills on outcomes after endovascular abdominal aortic aneurysm repair. STUDY DESIGN: One hundred sixty-four patients (mean age 71 years) underwent stent-graft repair. Patients were treated with four different types of stent-graft: first-generation (n = 58) and second-generation (n = 17) Ivancev-Malm

Objectives This study evaluated the role of pre-procedural clinical variables to predict procedural and clinical outcomes of catheter ablation in patients with long-lasting persistent atrial fibrillation (AF). Background Catheter ablation of persistent AF remains a challenging task. Methods Catheter ablation was performed in 90 patients (76 men, age 57 +/- 11 years) with long-lasting persistent AF

Methods currently used for surface display on insect cells and budded baculovirus, all utilize the sequences from class I transmembrane proteins. This gives rise to some problems when handling unknown genes or cDNAs encoding full-length proteins. First, the stop codon from the cloned gene will be located upstream of the sequence for the transmembrane region. Second, the chance of getting the seque

The analysis of Helicobacter pylori proteins is a demanding task for the elucidation of virulence factors, antigens and vaccines, all important for diagnosis, therapy and protection. In the "pre-genomic era" the purification of proteins was mostly performed by using various techniques such as detergent treatment of the bacterial cells, ultra-centrifugation, various chromatographic methods, antibod

BACKGROUND. Prostate specific antigen (PSA) is widely used for prostate cancer screening but its levels are influenced by many non cancer-related factors. The goal of the study is to estimate the effect of genetic variants on PSA levels. METHODS. We evaluated the association of SNPs that were reported to be associated with prostate cancer risk in recent genome-wide association studies with plasma
