The assay of lipid composition in red blood cells of 51 patients with iron-deficiency anemia (IDA) was conducted with the use of horizontal thin-layer chromatography, and the state of the end blood flow was studied with the ai of conjunctival biomicroscopy. It was found that in IDA patients the content of total lipids, phospholipids, free fatty acids, cholesterol, sphingomyelins, cardiolipins and phosphatidic acids increased and that of triglycerides decreased. The content of the rest fractions of total lipids in IDA patients was practically not changed. Variations in lipid composition of red blood cells lead to disorders in their functional activity. In IDA patients it is clinically expressed in the development of the sludge phenomenon that aggravates tissue hypoxia in women with this disease.

Introduction: Myelofibrosis (MF) is often characterized by a multifactorial anemia determined, in part, by bone marrow (BM) fibrosis, extramedullary erythropoiesis and splenomegaly. Ruxolitinib (RUX) is the first-in-class janus kinase 2 (JAK2) inhibitor approved for treatment of MF, proved to reduce spleen volume and decrease symptom burden. The red cell distribution width (RDW) is the measure of erythrocyte volume variability (anisocytosis).

Iron deficiency anaemia in a stable chronic intestinal failure cohort: Prevalence, associations and outcomes.

Background & Aims: Current estimates of the prevalence of iron deficiency anaemia (IDA) in patients with chronic intestinal failure (CIF) exceed those seen in general population, however, the studies to-date are limited. The aim of this study was to determine the point prevalence of IDA in a large cohort of stable home parenteral nutrition (HPN) dependent adults managed by a specialist Intestinal Failure Unit.
Methods: This was a retrospective cohort study of HPN-dependent adults managed by a national UK IF Reference Centre between 01/01/2019 and 31/12/2019.

Introduction: Exosomes play an important role in regulating physiological processes and mediating the systemic dissemination of various types of cancer. We investigated the association of exosomal tetraspanins CD9, CD63, and CD81 in patients with ovarian cancer (OC).
Material And Methods: We measured the plasma tetraspanins CD9, CD63, and CD81 by enzyme-linked immunosorbent assay in 91 patients who underwent treatment for OC between April 2018 and March 2024.

Prostate cancer (PCa) remains a critical global health challenge, with high mortality rates and significant heterogeneity, particularly in advanced stages. While early-stage PCa is often manageable with conventional treatments, metastatic PCa is notoriously resistant, highlighting an urgent need for precise biomarkers and innovative therapeutic strategies. This review focuses on the dualistic roles of sirtuins, a family of NAD+-dependent histone deacetylases, dissecting their unique contributions to tumor suppression or progression in PCa depending on the cellular context.
