This paper considers the dose-effect relationship for unstable chromosome aberration yields in human lymphocytes in very low-dose range. Data are presented for (60)Co γ-ray doses of 0, 10, 20, 40 and 1000 mGy. More than 5,000 metaphases were scored for each data point at the very low doses, and each cell was double-checked using a semi-automated metaphase finding/relocation system. Aberration yields of dicentrics plus centric rings followed an excellent linear dose response down to zero dose; the yields were significantly above the control frequency from 20 mGy.

The P2X4 receptor (P2X4R), a ligand-gated ion channel activated by ATP, plays a critical role in neuroinflammation, chronic pain, and cancer progression, making it a promising therapeutic target. In this study, we explored the design and synthesis of piperazine-based P2X4R antagonists, building on the structural framework of paroxetine. A series of over 35 compounds were synthesized to investigate structure-activity relationships (SARs) in a Ca²⁺-flux assay for P2X4R antagonistic activity.

Introduction: Thrombocytopenia is a common clinical problem in cancer patients undergoing high-dose chemotherapy and autologous hematopoietic stem cell transplantation (HSCT). It can occur as prolonged isolated thrombocytopenia (PIT) or secondary failure of platelet recovery (SFPR) and may cause potentially fatal bleeding. However, data on the treatment of post-transplant thrombocytopenia is still lacking.

Objective: Cancer survivors often face significant health-related quality of life (HRQoL) challenges. Although exercise has been proven to improve HRQoL in cancer survivors, the optimal dose and intensity of exercise for this population has not been fully determined. Adherence to exercise may vary based on exercise intensity, affecting results.

Unlabelled: Cladribine indirectly downregulates methylation of DNA, RNA, and histones by blocking the transfer of methyl groups from -adenosyl-methionine. The cladribine and rituximab combination showed a synergetic effect in treating B-cell lymphomas. Bortezomib (Velcade) is a Food and Drug Administration (FDA)-approved proteasome inhibitor for treating mantle cell lymphoma (MCL).

Background: The heterologous three-dose schedule of the protein subunit anti-COVID-19 SOBERANA®02 and SOBERANA® Plus vaccines has proved its safety, immunogenicity and efficacy in pediatric population, but durability of immunogenicity is not yet dilucidated. This study reports the safety and durability of the humoral and cellular responses in children and adolescents 5-7 months after receiving the heterologous vaccine schedule of SOBERANA® 02 and SOBERANA® Plus.
Methods: Children participating in a phase I/II clinical trial were followed-up for 5-7 months after the last dose.
