Quantitative phase information obtained by digital holographic microscopy (DHM) can provide new insight into the functions and morphology of single red blood cells (RBCs). Since the functionality of a RBC is related to its three-dimensional (3-D) shape, quantitative 3-D geometric changes induced by storage time can help hematologists realize its optimal functionality period. We quantitatively investigate RBC 3-D geometric changes in the storage lesion using DHM. Our experimental results show that the substantial geometric transformation of the biconcave-shaped RBCs to the spherocyte occurs due to RBC storage lesion. This transformation leads to progressive loss of cell surface area, surface-to-volume ratio, and functionality of RBCs. Furthermore, our quantitative analysis shows that there are significant correlations between chemical and morphological properties of RBCs.

Blood storage lesion induces cytosolic and membrane changes driven in part by hemoglobin (Hb) oxidation reactions within red blood cells (RBCs). A novel gel formulation containing the antioxidant curcuminoids in a biocompatible solvent system was used to deliver curcumin into RBCs. Incubation of peroxide treated RBCs stored in PBS with curcumin gel led to a reduction in prooxidant ferrylHb and recovery in ATP.

Background: Metabolic dysfunction-associated steatotic liver disease (MASLD) and its more severe form steatohepatitis (MASH) contribute to rising morbidity and mortality rates. The storage of fat in humans is closely associated with these diseases' progression. Thus, adipose tissue metabolic homeostasis could be key in both the onset and progression of MASH.

A 79-year old Caucasian male with metastatic hormone refractory prostate cancer and bilateral nephrostomy was admitted to the emergency department due to 4-day bloody urethral discharge, weakness and dizziness. The patient was treated with the luteinizing hormone-releasing hormone-antagonist and abiraterone acetate plus prednisone, dabigatran 150 mg bid (for atrial fibrillation and coronary heart disease) and 5-aminosalicylic acid for the management of mild ulcerative colitis. Imaging revealed bladder overdistention and blood analysis low levels of hematocrit (HCT) and hemoglobin (HGB) (HCT, 22%; HGB, 7.
