Exploring 4,7-Disubstituted Pyrimido[4,5-]pyrimidines as Antiviral and Anticancer Agents.

Thirteen new 4,7-disubstituted pyrimido[4,5-]pyrimidines were synthesized via a straightforward methodology starting from thiourea. The anti-proliferative activity of these compounds was evaluated across a diverse panel of eight cancer cell lines, with derivatives and showing efficacy against several hematological cancer types. Furthermore, all compounds were assessed for their antiviral potency against a panel of viruses.

Ovarian follicular flushing as a means of increasing oocyte yield and embryo production in cattle.

Context The number of developmentally competent cumulus-oocyte complexes (COCs) retrieved during Ovum Pick-Up (OPU) determines success in both bovine and human assisted reproduction. Follicular flushing for COC retrieval is practicsed widely in humans but not in cattle. Aims To determine the benefits of follicular flushing in cattle and assess the merits of a novel 16G double-lumen needle ('OxIVF') that flushes laterally to the needle shaft.

Synthesis of hydroxytyrosol analogs with enhanced antioxidant and cytostatic properties against MG-63 human osteoblast-like cells and their potential implications for bone health.

Sixteen novel hydroxytyrosol (HT) analogs with substitutions at the C-1 position of the HT aliphatic side chain were synthesized and evaluated for their cytostatic activity against MG-63 human osteoblast-like cells and for their antioxidant properties. The results revealed that these analogs exhibited significantly higher inhibitory activity compared with HT, which served as the positive control. Among these, the cyclo-substituted compounds stood out as particularly potent, demonstrating strong radical scavenging abilities and notable cytostatic effects against MG-63 cells.

Clinical features, treatment options and outcomes in primary cutaneous B-cell lymphomas: a real-world, multicenter, retrospective study.

Background: Primary cutaneous B-cell lymphomas (PCBCLs) are rare cutaneous neoplasms with limited literature regarding treatment options and associated treatment outcomes. This study aimed to investigate and present real-world treatment outcomes in patients with PCBCLs.

Methods: All patients with PCBCL who were treated in five major referral centers for cutaneous lymphoma in Greece over 10 years were retrospectively included with their baseline characteristics and treatment-associated outcomes collected and analyzed.

Case Report: Post-traumatic splenosis and potential pitfall for PSMA-PET.

Background: 18F-prostate specific membrane antigen (PSMA) PET is fast becoming the gold-standard in prostate cancer, both in staging of intermediate-/high-risk patients and in re-staging patients with biochemical failure. Several pitfalls of 18F-PSMA PET have been reported, and we report, to our best of knowledge, for the first time, a case which could have been falsely diagnosed as peritoneal spread.

Case Presentation: A 67-year-old patient with high-risk prostate cancer underwent staging with 18F-PSMA-1007 PET/CT (PSMA-PET/CT).
