Background: Recent studies demonstrate that prothrombotic antiphospholipid antibodies (aPL) are overrepresented in patients with myocardial infarction (MI) due to coronary artery disease (MICAD). However, it is not known whether aPL differ between the two subsets of MI: MICAD and MI with nonobstructive coronary arteries (MINOCA). Objectives: To determine whether aPL are associated with MINOCA or M

The COVID-19 pandemic has disrupted scientific gatherings and conferences, opening up opportunities for virtual learning platforms. Realizing the potential of online academic exchanges, the World Psychiatric Association (WPA) also developed virtual avenues and information systems for capacity building of mental health professionals across the world. Among its first such initiatives, the WPA organi

We have determined the effect of seven serine- and arginine-rich (SR) proteins and 15 heterogenous nuclear ribonucleoproteins (hnRNPs) on human papillomavirus type 16 (HPV16) late gene expression. Of the seven SR proteins analyzed here, SRSF1, SRSF3, and SRSF9 induced HPV16 late gene expression, and five of the SR proteins affected HPV16 L1 mRNA splicing. Of the 15 hnRNP proteins analyzed here, hn

Ex vivo manufactured red blood cells (RBC) generated from immortalized erythroid cell lines which can continuously grow are expected to become a significant alternative in future transfusion therapies. The ectopic expression of human papilloma virus (HPV) E6/E7 gene has successfully been employed to establish these cell lines. To induce differentiation and maturation of the immortalized cell lines

The surface expression of a recently described plasma glycoprotein called human complex-forming glycoprotein, hetergeneous in charge (protein HC) on a number of different human cell types was investigated. By means of direct and indirect immunofluorescence, protein HC was shown to be associated with the surface of virtually all cells of the investigated normal cell types including erythrocytes, pe

The molecular form and immunochemical properties of the J chain populations released on reduction and carboxymethylation of normal human plasma, milk, saliva and of plasma containing IgA or IgM M-components were investigated. A procedure was devised to release the entire J chain population from these various sources and to produce immunochemically identical J chain populations containing only J ch

Human fetal lever explants were found to secrete protein HC into the medium in molar amounts comparable to those of albumin, alpha 1-antitrypsin and orosomucoid. Incorporation of a radioactive amino acid from the medium into the secreted protein HC demonstrated de novo synthesis. The secreted protein HC had the same size and electrophoretic mobility as protein HC of plasma and urine and gave a rea

This report concerns six cases of multiple myeloma characterized by either no demonstrable monoclonal immunoglobulin in plasma or urine or by trace amounts (less than or equal to 0.1 g/l) of monoclonal kappa chains in the urine. In all cases there was an infiltration of the bone marrow by plasma cells containing kappa chains but no heavy chains. A retrospective analysis was made of 126 consecutive

Lancefield extracts of 19 types of group A streptococci as well as one group C and one group G strain were examined for agglutination of human red cells coated with various anti-Rh antibodies. Fourteen extracts agglutinated one or more of the coated cell samples, while five did not. The agglutination was inhibited by Fc but not by Fab fragments of human IgG. After mouse passages, three of the non-

After electrophoresis of an alkaline extract of type 15 group A streptococci, three main precipitation lines were obtained in diffusion experiments against commercial human polyclonal IgG (lines 1, 2 and 3). Nineteen of 23 sera (83%) from apparently healthy human individuals gave line 3, while 6 of them (26%) gave line 1. The sera giving line 1 did also give line 3. Line 2 was obtained with 2 sera

Of 30 bacterial species tested 18 stimulated DNA synthesis in human blood lymphocytes. The maximum response was after 3-4 days of culture suggesting a mitogenic effect. This was confirmed by the induction of polyclonal antibody production shown by a plaque assay. Most bacterial species increased the DNA synthesis in B-enriched lymphocytes and unseparated lymphocytes but had negligible activity on

This roadmap outlines the role semiconductor-based materials play in understanding the complex biophysical dynamics at multiple length scales, as well as the design and implementation of next-generation electronic, optoelectronic, and mechanical devices for biointerfaces. The roadmap emphasizes the advantages of semiconductor building blocks in interfacing, monitoring, and manipulating the activit

Here, we report a method for time-resolved, longitudinal extraction and quantitative measurement of intracellular proteins and mRNA from a variety of cell types. Cytosolic contents were repeatedly sampled from the same cell or population of cells for more than 5 d through a cell-culture substrate, incorporating hollow 150-nm-diameter nanostraws (NS) within a defined sampling region. Once extracted

BACKGROUND: Renal cell carcinoma (RCC) accounts for more than 80% of kidney cancers in adults, and obesity is a known risk factor. Regular consumption of sweetened beverages has been linked to obesity and several chronic diseases, including some types of cancer. It is uncertain whether soft drink and juice consumption is associated with risk of RCC. We investigated the associations of soft drink a

European VAT and the Sharing Economy aims to understand whether the current European Value Added Tax (EU VAT) system is sufficiently equipped to deal with the ongoing transformation of the supply chain as well as the increasing digitalization of the economy ushered in by the rise of multisided digital platforms. New digital platforms such as those of the sharing economy, have dramatically expanded

PURPOSE: This study aimed to investigate inequality and heterogeneity in health-related quality of life (HRQoL) and to provide EQ-5D-5L population reference data for Sweden.METHODS: Based on a large Swedish population-based survey, 25,867 respondents aged 30‒104 years, HRQoL is described by sex, age, education, income, economic activity, health-related behaviours, self-reported diseases and condit
