Melts and fluids are ubiquitous vectors of mass transport in natural systems. We have developed an open-source package to analyze ab initio molecular-dynamics simulations of such systems. We compute structural (bonding, clusterization, chemical speciation), transport (diffusion, viscosity) and thermodynamic properties (vibrational spectrum).

Source: Kay Stewart, RVT, RLATG, CMAR; Valerie A. Schroeder, RVT, RLATG. University of Notre Dame, IN The collection of blood from mice and rats for analysis can be done through a variety of methods. Each method of collection has variations in the type of restraint required, the invasiveness of the procedure, and the necessity of a general anesthetic.1Historically, the use of the retro-orbital sinus cavity has been used, but not without debate. The controversy related to the potential tissue...

Repeated blood sampling is necessary and important in animal research. We developed a novel, non-lethal and reliable method for repeated blood collection from adult zebrafish, and applied this method to the study of blood biochemistry, including glucose metabolism.
FAQs
Codominant expression means that neither inherited allele is treated as hidden by the other. In an AB individual, the A and B allele products each contribute a distinct carbohydrate marker to the red-cell surface. This makes AB inheritance a useful biological example of two allelic products being expressed together.
Because AB plasma normally lacks anti-A and anti-B antibodies, the immune consequences of exposure to A- or B-marked red cells differ from those associated with ABO groups whose plasma contains these antibodies. This antibody profile is therefore central to understanding compatibility and why antigen and antibody findings must be interpreted together.
AB-related findings provide context for interpreting hemolytic reactions because they describe both the red-cell antigen pattern and the plasma antibody pattern. When these laboratory features are known, clinicians can relate an observed reaction to transfusion compatibility considerations rather than viewing the reaction in isolation. This makes blood-group information useful in clinical interpretation as well as classification.
Identification relies on a combined antigen-and-antibody assessment rather than on inheritance information alone. Testing examines the red-cell surface for the A and B antigens and evaluates plasma for the corresponding ABO antibody pattern. Agreement between these two types of findings strengthens interpretation and supports subsequent compatibility decisions.
AB typing supplies information needed for donor-recipient matching and safer transfusion decisions. The result is considered alongside relevant antigen and antibody findings, because these features help assess compatibility. Consequently, typing provides a practical basis for selecting and evaluating transfusion pairings, while also giving clinicians a defined blood-group context for interpreting possible hemolytic reactions.
It links several core biological ideas in one system: allele inheritance, codominant expression, carbohydrate markers on cell surfaces, antibody-mediated immune recognition, and clinical compatibility. Studying AB status therefore connects genetic information with observable cellular traits and with practical laboratory interpretation, making it a concise example of how molecular features influence biological outcomes.
