Abstract: The present disclosure provides methods of treating, stabilizing, or lessening the severity or progression of an acute respiratory disorder.

Abstract: The present invention is directed to a method for selecting compounds for use in treating sickle cell disease in a patient. The method comprises the steps of selecting a first set of HbS ligands from a first group of chemical compounds, selecting from the first set of HbS ligands a seconds set that exhibit inhibition of HbS polymerization, and selecting from the second set a third set that display anti-sickling activity of red blood cells when in the presence thereof. The method may include the step of performing a methemoglobin S proteolysis assay measuring a percent protease protection for each compound. The method may additionally include the steps of measuring HbS aggregation, inhibition of protease, deoxy-HbS gelation inhibition activity, O2 affinity of HbS, and cytotoxic effect to cell activity. The method may further include assessing red blood cell morphology, and eliminating compounds that contain moieties that bind to heme.

Abstract: Apparatus and a method are described, wherein a coagulator accelerator is added to a container to achieve agglutination of blood cells when centrifuging whole blood, allowing the serum to be more easily poured off. The accelerator is selected from polymeric amines that are either polymerized amino acids or vinyl addition polymer amines, with a specified molecular weight range, the vinyl addition amines being selected to avoid lysing the blood cells.
