BACKGROUND: sIgE and sIgG4 detection is necessary for more accurate and effective type I hypersensitivity diagnostics and the estimation of disease development. Typically, the analyses of these antibodies are performed separately with the help of various specialized systems. The aim of this study was to develop a microarray-based method for the simultaneous quantitative detection of sIgE and sIgG4 to the most common allergens in a single sample. METHODS: A quantitative method for the simultaneous detection of sIgE and sIgG4 was developed based on the technology of hydrogel microchips previously designed at Engelhardt Institute of Molecular Biology, Russian Academy of Sciences (EIMB RAS)...

BACKGROUND: Total immunoglobulin E (IgE) is a therapeutic target in allergic diseases. DNA methylation in white blood cells (WBCs) was associated with total IgE in an epigenome-wide association study (EWAS) of Caucasians. Whether DNA methylation of eosinophils explains those findings is insufficiently understood. METHODS: We tested for association between genome-wide DNA methylation in WBCs and total IgE in two studies of Hispanic children: the Puerto Rico Genetics of Asthma and Lifestyle Study (PR-GOAL, n = 306) and the Genes-environments and Admixture in Latino Americans (GALA II, n = 573)...

In warm-blooded vertebrates, the α- and β-globin genes are organized in domains of different types and are regulated in different fashion. In cold-blooded vertebrates and, in particular, the tropical fish Danio rerio, the α- and β-globin genes form two gene clusters. A major D. rerio globin gene cluster is in chromosome 3 and includes the α- and β-globin genes of embryonic-larval and adult types. The region upstream of the cluster contains c16orf35, harbors the main regulatory element (MRE) of the α-globin gene domain in warm-blooded vertebrates...

BACKGROUND: Currently, N-terminal pro-B-type natriuretic peptide (NT-proBNP) and its physiologically active counterpart, BNP, are most frequently used as biomarkers for diagnosis, prognosis, and disease monitoring of heart failure (HF). Commercial NT-proBNP and BNP immunoassays cross-react to varying degrees with unprocessed proBNP, which is also found in the circulation. ProBNP processing and immunoassay response are related to O-linked glycosylation of NT-proBNP and proBNP. There is a clear and urgent need to identify the glycosylation sites in the endogenously circulating peptides requested by the community to gain further insights into the different naturally occurring forms...

INTRODUCTION: Adequate functioning of the blood-brain barrier (BBB) is important for brain homoeostasis and normal neuronal function. Disruption of the BBB has been described in several neurological diseases. Recent reports suggest that an increased permeability of the BBB also contributes to increased seizure susceptibility in patients with epilepsy. The endothelial glycocalyx is coating the luminal side of the endothelium and can be considered as the first barrier of the BBB. We hypothesise that an altered glycocalyx thickness plays a role in the aetiology of temporal lobe epilepsy (TLE), the most common type of epilepsy...

The semaphorins and the plexins are a family of large, cysteine-rich proteins originally identified as regulators of axon growth and lymphocyte activation that are now known to provide motility and positional information for a number of cell and tissue types. For example, our group and others have shown that some malignancies over express Semaphorin 4D (S4D), which acts through its receptor Plexin-B1 (PB1) on endothelial cells to attract blood vessels from the surrounding stroma for the purpose of supporting tumor growth...

The presence of activating mutations in the EGFR gene influences cell proliferation, angiogenesis, and increases metastatic ability; it has a significant impact on the choice of medical therapy of non-small cell lung cancer (NSCLC). The use of targeted therapy with tyrosine kinase inhibitors requires performance of appropriate genetic tests. The aim of this study was to design a real-time PCR-based diagnostic kit for fast and cheap of EGFR mutations testing in paraffin blocks and plasma, and kit validation using samples from patients with NSCLC, and also comparative estimation of diagnostic features of real-time PCR with wild type blocking and digital PCR for mutation testing in blood plasma...

Central nervous system infratentorial superficial siderosis (iSS) is increasingly detected by blood-sensitive MRI sequences. Despite this, there are no standardized diagnostic criteria, and the clinical-radiological spectrum, causes and optimum investigation strategy are not established. We reviewed clinical and radiological details of patients with iSS assessed at a specialist neurological center from 2004-2016 using pre-defined standardized radiological criteria. All imaging findings were rated blinded to clinical details...

The VI European Guidelines for Cardiovascular Prevention recommend combining population and high-risk strategies with lifestyle changes as a cornerstone of prevention, and propose the SCORE function to quantify cardiovascular risk. The guidelines highlight disease specific interventions, and conditions as women, young people and ethnic minorities. Screening for subclinical atherosclerosis with noninvasive imaging techniques is not recommended. The guidelines distinguish four risk levels (very high, high, moderate and low) with therapeutic objectives for lipid control according to risk...

Many current malaria vaccines target the pre-erythrocytic stage of infection in the liver. However, in malaria-endemic regions, increased blood stage exposure is associated with decreased vaccine efficacy, thereby challenging current vaccine efforts. We hypothesized that pre-erythrocytic humoral immunity is directly disrupted by blood stage infection. To investigate this possibility, we used Plasmodium-antigen tetramers to analyze B cells after infection with either late liver stage arresting parasites or wild-type parasites that progress to the blood stage...

BACKGROUND: Panel reactive antibody (PRA) reduction protocols are used to decrease anti-HLA antibodies with concomitant PRA monitoring as a measure of successful treatment prior to organ and haploidentical blood and marrow transplant (BMT). We hypothesized that the more sensitive flow cytometry (FC) based assays for PRA [FlowPRA(®) and Luminex(®) based Single Antigen Bead (SAB)] would also correlate with the ability to find compatible platelets for allosensitized recipients. METHODS: A female patient with myelodysplastic syndrome and a high HLA class I PRA [>90% PRA and cPRA by complement-dependent cytotoxicity (CDC) assay and Flow PRA] required allogeneic BMT...
