Postirradiation administration of Leukotrophin to whole-body irradiated mice was associated with increased LD50/30 and DRF. As indicated by 59Fe uptake and ESC number, haemopoiesis was significantly stimulated in spleen and bone marrow after Leukotrophin application to irradiated mice. DNA content and the uptake of 3H-thymidine in DNA was significantly enhanced in the thymus and bone marrow of irradiated and Leukotrophin-treated mice. The micronucleus test confirmed that Leukotrophin is a therapeutic agents, while administered before irradiation it does not influence the initial radio-lesions.

UVB irradiation induces diverse modalities of regulatory cell death in keratinocytes. Recently, the pattern of coexistence of pyroptosis, apoptosis, and necroptosis has been termed PANoptosis; however, whether PANoptosis occurs in keratinocytes in UVB-induced skin injury remains unclear. We observed that the key molecules of GSDMD-mediated pyroptosis, apoptosis, and necroptosis, which are N-terminal GSDMD, cleaved caspase-3/PARP, and phosphorylated MLKL, respectively, were elevated in keratinocytes of UVB-challenged mice and human skin tissue.

T cell lymphoma constitutes a complex group of diseases, characterized by heterogeneous molecular features and clinical symptoms, and a dismal outcome no matter the therapeutic strategy chosen. In an attempt to improve patients' survival chances, treatment combinations (chemotherapy, radiotherapy, immunotherapy, gene therapy and thermotherapy) have been tested for their synergistic effects that may dramatically improve outcomes and reduce the side effects of each single modality treatment when therapeutic effects add up while side effects are distributed. In this context, nanoscale drug delivery agents have been developed and exploited to enhance the release of drugs in the treatment of several diseases, showing potential benefits in terms of pharmaceutical flexibility, selectivity, dose reduction and minimization of adverse effects.

Currently, Ovarian Cancer (OC) is the most lethal gynecological malignancy. In most patients, it progresses without clinical signs or symptoms, leading to a late diagnosis when it has already spread in the peritoneal cavity as peritoneal carcinomatosis (PC). To date, OC PC management is based on cytoreductive surgery to remove the macroscopic disease, followed by chemotherapy.

The two obstacles for treating glioma are the skull and the blood brain-barrier (BBB), the first of which forms a physical shield that increases the difficulties of traditional surgery or radiotherapy, while the latter prevents antitumor drugs reaching tumor sites. To conquer these issues, we take advantage of the high penetrating ability of sonodynamic therapy (SDT), combined with a novel nanocomplex that can easily pass the BBB. Through ultrasonic polymerization, the amphiphilic peptides (CGRRGDS) were self-assembled as a spherical shell encapsulating a sonosensitizer Rose Bengal (RB) and a plant-derived compound, sulforaphane (SFN), to form the nanocomplex SFN@RB@SPM.
