Article Abstract
Granted with a potent ability to interact with and tolerate oxidative stressors, RBCs scavenge most reactive oxygen and nitrogen species (RONS) generated in circulation. This essential non-canonical function, however, renders RBCs susceptible to damage when vascular RONS are generated in excess, making vascular redox imbalance a common etiology of anemia, and thus a common indication for transfusion. This accentuates the relevance of impairments in redox metabolism during hypothermic storage, as the exposure to chronic oxidative stressors upon transfusion could be exceedingly deleterious to stored RBCs. Herein, we review the prominent mechanisms of the hypothermic storage lesion that alter the ability of RBCs to scavenge exogenous RONS as well as the associated clinical relevance.

In a subset of patients with systemic mastocytosis (SM), an associated hematologic neoplasm (AHN) is identified. Most AHN are myeloid neoplasms, whereas lymphoid neoplasms are uncommon. We report on a 70-year-old female patient with bone marrow mastocytosis (BMM) associated with primary cutaneous follicle center lymphoma (PCFCL).

Background: Human platelets experience structural and functional deterioration during extra-corporeal storage at either room temperature or in the cold, impairing their reactivity and diminishing their hemostatic effectiveness following transfusion. PECAM-1 is an inhibitory receptor on platelets that exerts its inhibitory effects via phosphorylation of tyrosine residues that lie within its cytoplasmic immunoreceptor tyrosine-based inhibitory motifs (ITIMs). The purpose of this investigation was to attempt to restore platelet reactivity by impairing the inhibitory activity of PECAM-1.

Background: Cold-stored platelets (CSP) are now being used to treat acute bleeding. However, as CSP are less suitable for prophylaxis, both room temperature (RT) platelets and CSP will be required, which complicates inventory management. The production of CSP "on-demand" from RT platelets may be a desirable option.

Mesenchymal stem cells (MSCs) are a type of multipotent, non-hematopoietic cells of mesodermal origin. Due to their strong immunomodulatory, immunosuppressive, and regenerative potential, MSCs are used in cell therapy for inflammatory, immune-mediated, and degenerative diseases. Exosomes derived from MSCs have several advantages over MSC therapy, including non-immunogenicity, lack of infusion toxicity, ease of isolation, manipulation, and storage, cargo specificity, and the absence of tumor-forming potential and ethical concerns.

Background: Photon-counting detector (PCD) CT represents a transformative advancement in radiological imaging, offering superior spatial resolution, enhanced contrast-to-noise ratio, and reduced radiation dose compared with the conventional energy-integrating detector CT.
Aim: To evaluate PCD CT in oncologic imaging, focusing on its role in tumor detection, staging, and treatment response assessment.
Methods: We performed a systematic PubMed search from January 1, 2017 to December 31, 2024, using the keywords "photon-counting CT", "cancer", and "tumor" to identify studies on its use in oncologic imaging.
