Abstract

The Bohr factor, phi = delta log Po2/deltapH, was determined at various levels of hemoglobin O2 saturation (SO2) in fresh whole blood of the duck. Plasma pH was varied by either changing PCO2 of the blood at constant base excess (CO2 Bohr factor, phiCO2) or by addition of NaHCO3 and HCl at constant PCO2 (fixed acid BOHR factor, phiAH). No differences were found between phiCO2 and phiAH at SO2 levels between 20 and 85%, and there was no saturation dependence of the Bohr factor, its average value being -0.44. It is concluded that in whole blood of this bird species CO2 exerts no direct effect on the O2 affinity of hemoglobin.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Alzheimer's Disease: MS4A

Variants within the membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease in genome-wide association studies. Here is the latest research on Alzheimer's disease and MS4A.
