In the present study, lipoprotein metabolism was investigated during compensatory hyperplasia of bone marrow after haemolysis induced by phenylhydrazine (20 mg/kg b.w.) administration in rats. The rats were sacrificed at different time intervals (0, 1, 2 and 5 days) after phenylhydrazine treatment. Analysis of the different fractions of lipoproteins has shown that during bone marrow hyperplasia there is an alteration of lipoprotein profiles, mainly due to a decrease of HDL2 and HDL3 subfractions.

Enhancing Medication Safety: Reducing Administration Errors in Oncology Setting.

Asian Pac J Cancer Prev

January 2025

Center Incharge, Sultan Qaboos Comprehensive Cancer Care and Research Centre (SQCCCRC), University Medical City, Muscat, Oman.

Purpose: This project aimed to minimize medication errors and improve safe medication administration in an oncology setting in Muscat, Oman.

Methods: The study, spanning from the second quarter of 2022 to the first quarter of 2023, employed a one-group pretest-posttest quasi-experimental design, assessing key performance indicators (medication error and medication administration errors rates per 1000 patient days) on quarterly basis before and after implementing targeted interventions.  Interventions focused on medication management processes and Healthcare Informatics System (HIS), Environment and equipment, and Education The project utilized the FOCUS PDCA (find, organize, clarify, understand, select, plan, do, check and act) methodology.

Aplastic anemia (AA) is a life-threatening bone marrow failure syndrome. The advent of next-generation sequencing (NGS) has shed light on the link between somatic mutations (SM) and the efficacy of immunosuppressive therapy (IST) in AA patients. However, the relationship between SM and hematopoietic stem cell transplantation (HSCT) has not been extensively explored.

Objectives: To investigate the factors affecting laboratory data and computed tomography (CT) attenuation values of L1 trabecular and femoral bone marrow, potential markers for differentiating between adult-onset Still's disease and intravascular large B-cell lymphoma.

Methods: We conducted a retrospective observational study on patients diagnosed with adult-onset Still's disease or intravascular large B-cell lymphoma. Clinical and laboratory data, and CT attenuation values of the bone marrow were compared.

Studies of the aging transcriptome focus on genes that change with age. But what can we learn from age-invariant genes-those that remain unchanged throughout the aging process? These genes also have a practical application: they can serve as reference genes in expression studies. Reference genes have mostly been identified and validated in young organisms, and no systematic investigation has been done across the lifespan.
