Malaria is a major global cause of deaths and a vaccine is urgently needed.

During atrial fibrillation (AF), time-frequency analysis of atrial signal has been applied to describe fibrillatory frequency trends. Recently, temporal changes in spectral shape have been investigated using the spectral profile technique. This profile is computed recursively by fitting each short-time log-spectrum to a spectral template, using amplitude scaling and frequency shifting. The purpose

Objectives: To assess the risk of lymphoproliferative disease or other malignancy (standardised incidence ratios (SIRs)), in patients with primary Sjogren's syndrome according to the American-European Consensus Criteria (AECC), compared with patients with sicca syndrome (non-AECC) and the background population. To identify predictors of malignancy and describe lymphoma types and survival probabili

Medin amyloid is found in the medial layer of the aorta in almost 100% of the Caucasian population over 50 years of age. The medin fragment is 5.5 kDa and derives from the C2-like domain of the precursor protein lactadherin. We have previously reported immunohistochemical findings showing that medin amyloid co-localizes with elastic fibers of arteries and herein we show that lactadherin also is as

We present a new type of nanometer-scale semiconductor nonlinear device, called self-switching device (SSD). The device was realized by simply etching insulating grooves into a semiconductor, between which a narrow channel with a broken symmetry was formed. Because of the asymmetry in the channel boundary, an applied voltage V not only changes the potential profile along the channel direction, but

The human pathogen Haemophilus influenzae causes mainly respiratory tract infections such as acute otitis media in children and exacerbations in patients with chronic obstructive pulmonary disease. We recently revealed the crystal structure of H. influenzeae protein E (PE), a multifunctional adhesin that is involved in direct interactions with lung epithelial cells and host proteins. Based upon th

Serine proteases of the S1 family have maintained a common structure over an evolutionary span of more than one billion years, and evolved a variety of substrate specificities and diverse biological roles, involving digestion and degradation, blood clotting, fibrinolysis and epithelial homeostasis. We here show that a wide range of C-terminal peptide sequences of serine proteases, particularly fro

This report provides a compendium of current information relating to radiation dose to patients, including biokinetic models, biokinetic data, dose coefficients for organ and tissue absorbed doses, and effective dose for major radiopharmaceuticals based on the radiation protection guidance given in Publication 60 (ICRP, 1991). These data were mainly compiled from Publications 53 , 80, and 106 (ICR

OBJECTIVE: To assess adherence to isoniazid preventive therapy (IPT) in children exposed to adult pulmonary tuberculosis (TB) at home. METHODS: Children were enrolled on IPT if they were aged <= 5 years or 5-15 years and presented a tuberculin skin test induration of >= 1.0 mm. Children were included from the demographic surveillance system of the Bandim Health Project in Bissau, Guinea-Bissau. Th

Optimal linearly constrained minimum variance (LCMV) filtering methods have recently been applied to fundamental frequency estimation. Like many other fundamental frequency estimators, these methods are constructed using an estimate of the inverse data covariance matrix. The required matrix inverse is typically formed using the sample covariance matrix via data partitioning, although this is well-

Hepatitis C virus (HCV) infection is a frequent problem in hemodialysis units. The prevalence and incidence of HCV infection over a decade were studied in a nephrology unit affected by previous nosocomial HCV transmission. The HCV non-structural 5B protein gene was sequenced to achieve phylogenetic analysis of a new (incident) case of infection. Proportions of patients who were and were not infect

Variation in transcription factor 7-like 2 (TCF7L2), the strongest genetic risk factor for type 2 diabetes (T2D), may play a role in prostate cancer (PCa) depending on lifestyle factors. The aims of this study were to determine if TCF7L2 rs7903146 is associated with risk of PCa and if the association is modified by lifestyle factors independently of T2D status.

Malaria caused by Plasmodium falciparum (P. falciparum) remains a major cause of morbidity and mortality, particularly in sub-Saharan Africa. Immunity develops gradually after repeated exposure and is largely mediated by antibodies, yet the mechanisms regulating the development and function of humoral immunity, including the roles of B-cell subsets and inflammatory mediators, remain incompletely u

Abstract – Background: Cytological examination of a fine-needle aspirate (FNA) is a minimally invasive modality that is increasingly used in the diagnosis of lymphoma. Flow cytometry and other ancillary tests make an important contribution to the diagnostic value of FNAs of lymphoid lesions. This review follows the recent publication of the first edition of the WHO Reporting System for Lymph Node,

BACKGROUND: In patients with acute coronary syndrome (ACS) undergoing percutaneous coronary intervention (PCI) and who are treated with direct oral anticoagulants (DOACs), dual antithrombotic treatment without aspirin is recommended. Evidence comparing P2Y 12 inhibitor strategies in this setting is limited. AIMS: This study aimed to compare outcomes with ticagrelor versus clopidogrel as part of

The dissociation of NO is a critical step in its catalytic reduction to N2, which is key to automotive exhaust treatment. Here, we examine the role of Rh atomic steps in the NO dissociation reaction under 0.05 mbar NO. We use a Rh crystal sample curved around the (111) direction and ambient-pressure X-ray photoelectron spectroscopy to probe different Rh surfaces subject to the very same reaction c

Immunoglobulin G subclass deficiencies (IgGSD) are associated with recurrent respiratory tract infections. Tools to identify patients with IgGSD who benefit from immunoglobulin G replacement therapy (IgGRT) are lacking. This crossover study evaluated the number of antibiotic-demanding infections on and after up to 18 mo off IgGRT in 28 patients with IgGSD. Pneumococcal antibodies against 21 seroty

Background The impact of baseline anemia in a contemporary acute coronary syndrome (ACS) population undergoing percutaneous coronary intervention in the era of predominant radial artery access, potent P2Y12 inhibition, and rare use of glycoprotein IIb/IIIa inhibitors has not been adequately studied. Methods and Results ACS patients who underwent percutaneous coronary intervention between 2014 and
