Blood groups – minuses and pluses. Do the blood group antigens protect us from infectious diseases?

Relationship of blood groups to pemphigus: Do blood group antigens have a biological role? A Case-control study

Background: ABO blood group antigens may play a role in the pathophysiology of certain diseases. Several studies have investigated the relation between blood group and autoimmune disorders. In this research, we evaluated the associations between ABO blood types and rhesus (Rh) factor in pemphigus patients.Methods: In this case-control, hospital-based study, we evaluated the prevalence of blood ...

The Pluses and Minuses of Obtaining Measurements from Digital Scans

Digital scanners are commonplace and are used in many different applications to obtain three-dimensional shapes and linear and circumferential measurements. Even though scanners can be highly accurate, measurements obtained from scanners can vary depending on how an object is scanned, aligned and processed. In this study, we examined the effect of three different alignment methods of foot scans...

Blood groups: In Health and Diseases

ABO blood type antigens are polymorphic, inherited structures presented on the surface of red blood cells. Although ABO blood group antigens is the most important antigens in transfusion medicine, its main role is not clearly clarified. Correlation between ABO blood group and susceptibility to certain infectious and non-infectious diseases is a controversial issue. Since, lack of blood type ant...

Relationship of blood groups to disease: do blood group antigens have a biological role?

The pluses and minuses of R0.

The concept of the basic reproduction number (R0) occupies a central place in epidemic theory. The value of R0 determines the proportion of the population that becomes infected over the course of a (modelled) epidemic. In many models, (i) an endemic infection can persist only if R0>1, (ii) the value of R0 provides a direct measure of the control effort required to eliminate the infection, and (...
