Structure Determination Of A Bioengineered Human/Porcine Factor Viii For Hemophilia A Treatment, And Improvements To The Human Factor Viii Model, Ian Smith

Graduate Student Symposium

Blood coagulation factor VIII (FVIII), is a non-enzymatic cofactor which plays a crucial role in the formation of a stable blood clot. Absence or deficiency of FVIII results in the blood disorder hemophilia A; with symptoms including internal hemorrhaging and the inability to stop bleeding from open wounds. Treatment of hemophilia A relies on infusions of blood, plasma, or protein concentrates to replace FVIII. Unfortunately, approximately 30% of patients receiving replacement FVIII generate pathologic anti-FVIII inhibitory antibodies, which both reduce the effectiveness of the FVIII therapeutic and increase the severity of hemophilia A symptoms.

We have determined the molecular structure …

Cll Metabolism Is Regulated By Prognostic Factors, Modulated By Stroma And Abrogated By Pi3k Inhibition, Hima Vangapandu

Dissertations & Theses (Open Access)

Metabolism of chronic lymphocytic leukemia (CLL), a disease characterized by the relentless accumulation of mature B cells has been little explored. Bone marrow stromal cells provide a survival benefit to CLL cells, in part through PI3K/AKT pathway. Compared with proliferative B-cell lines, metabolic fluxes of oxygen and lactate were low in quiescent malignant B lymphocytes from CLL patients. Glycolysis (extracellular acidification rate, ECAR) was consistently low in CLL samples, but oxygen consumption (OCR) varied considerably. Higher OCR was associated with poor prognostic factors such as ZAP 70 positivity, unmutated IgVH, high β2M levels, and higher Rai stage. Co-culture with the …

Reduction Of Oxidative Stress And Storage Lesions (Rcsl) In Red Blood Cells - Analysis Of Ascorbic Acid (Aa), N-Acetylcysteine Amide (Ad4), And Serotonin (5-Ht), Shanmuka Gadiraju

Undergraduate Research Posters

Oxidative stress is a common occurrence in red blood cell (RBC) storage in blood banks throughout the world. Typically RBC units stored under routine standard protocol (stored in SAGM-CPD additive solution) can only be kept up to 42 days for transfusion usage before being discarded. I am studying the effects of Ascorbic Acid (AA), N-acetylcysteine amide (AD4), and Serotonin (5-HT) as additives in blood bank storage because I want to find out if these additives can reduce storage-induced oxidative stress on red blood cells (RBCs), in order to help my reader understand how potential blood storage additives can affect the …
