1. ABO blood group association and COVID-19. COVID-19 susceptibility and severity: a review
Abstract Introduction The SARS-CoV-2 pandemic has been affecting the health and economic, as well as social, life of the entire globe since the end of 2019. The virus causes COVID-19, with a wide range of symptoms among the infected individuals, from asymptomatic infection to mortality. This, along with a high infection rate, prompted efforts to investigate

2. The relevance of a bank with genotyped platelets donors
ABSTRACT Objective: Describe the clinical and laboratory characteristics and the transfusion strategy of patients at Hospital Israelita Albert Einstein with platelet refractoriness and identify their etiological characteristics. Standardize the platelet immunofluorescence technique by flow cytometry as a test for platelet compatibility in immune platelet re

3. Structural diversity and biological importance of ABO, H, Lewis and secretor histo-blood group carbohydrates
ABSTRACT ABO, H, secretor and Lewis histo-blood system genes control the expression of part of the carbohydrate repertoire present in areas of the body occupied by microorganisms. These carbohydrates, besides having great structural diversity, act as potential receptors for pathogenic and non-pathogenic microorganisms influencing susceptibility and resistanc

4. Non-association between anti-Toxoplasma gondii antibodies and ABO blood group system
Toxoplasma gondii infects humans through the gastrointestinal tract (GIT), which elicits humoral immune response with specific antibodies. The expression of the ABO blood group glycoconjugates also occurs in this same system and may influence the human susceptibility of infection by T. gondii. The aim of the present study was to investigate the association b

5. Estudo das alterações moleculares do gene ABO em doadores de sangue fenotipados como A3 e A3B / ABO gene molecular alterations in blood bank donators phenotyped as A3 e A3B
ABO blood system is the most important blood group in transfusional medicine. Actualy, the blood group type in blood donors and receptors is determined by serological laboratorial tests, complemented by human DNA blood tests that assure the correct blood group determination for the blood donor and receptor, optimizing transfusional safety. Studies on blood s

6. Fibrinogenio, FVII, FVIII, FIX, FX e FXI como fatores de risco para tromboembolismo venoso em pacientes de uma população brasileira / Fibrinogen, FVII, FVIII, FIX, FX and FXI as risk factors for venous throembolism among patients of a Brazilian population
Nos últimos anos tem sido demonstrada uma associação entre níveis elevados de certos fatores da coagulação e risco de tromboembolismo venoso (TEV). Entretanto, o número de estudos é pequeno e a maioria estão restritos a populações caucasóides. Neste estudo caso-controle emparelhado por idade, sexo e etnia investigamos os níveis plasmáticos do f

8. Inhibition of cholera toxin binding to membrane receptors by pig gastric mucin-derived glycopeptides: differential effect depending on the ABO blood group antigenic determinants.
The capacity of pig gastric mucin-derived glycopeptides to interfere with the binding of cholera toxin (CT) to membrane receptors was studied. Two types of glycopeptide preparations with or without human blood group A antigenic activity were assayed for comparison in a system in which the target for the toxin was rat erythrocyte ghosts. Blood group A-active

9. Detection and quantitation of tetanus antitoxin in blood donations.
Passive haemagglutination and IEOP have been used both to detect and to measure tetanus antitoxin in human donor sera. Forty percent of blood donors had detectable antitoxin but only 9% had levels suitable for production of human antitetanus immuoglobulin (larger than or equal to 2 IU/ml). The incidence of high titre antitoxin was significantly greater in me

10. Binding of cholera toxin to pig intestinal mucosa glycosphingolipids: relationship with the ABO blood group system.
A search for compounds from intestinal mucosa of pigs carrying and not carrying blood group A-active substances (A+ and A- pigs, respectively) capable of binding cholera toxin (CT) was performed. Glycolipid extracts from a pool of pig intestinal mucosa resolved in thin-layer chromatography (TLC) revealed the presence of six to eight compounds capable of bind

11. In vitro inhibition of adhesion of Candida albicans clinical isolates to human buccal epithelial cells by Fuc alpha 1----2Gal beta-bearing complex carbohydrates.
The role of cell surface glycoconjugates as possible adhesion receptors for Candida albicans yeasts on human buccal epithelial cells was investigated by using a quantitative radiometric assay involving 14C-metabolically labeled microorganisms. Various structurally defined soluble glycopeptides and oligosaccharides were tested at a low concentration (1 mg/ml)

12. Self-nonself concept for cancer and diseases previously known as “autoimmune” diseases
The illegitimate glycosphingolipid antigens of the P blood group system and of the Forssman (Fs) tissue antigen in adenocarcinoma which are foreign to the host suggest the self-nonself concept which applies also to numerous other diseases such as rheumatoid arthritis, lupus, gluomerulonephritis, and idiopathic acute hemolytic anemia. In the presence of the g
