Arsenic trioxide (ATO) in combination with all-trans retinoic acid (ATRA) has been shown to be effective in both adult and pediatric patients with acute promyelocytic leukemia (APL). Addition of ATO to conventional chemotherapy could lead to a reduction in the doses of cytotoxic agents, but the long-term safety of ATO is not fully understood, especially in children. The Japan Children's Cancer Group conducted a risk-stratified prospective study to investigate safety and efficacy of ATO in children with newly diagnosed APL by replacing all three intensification phases with ATO.

Understanding and controlling the degradation conditions of polymers is essential to achieve an environmentally friendly recycling of polymeric materials without deterioration. In this study, we investigated the disassembly of microparticle-based polymer films into the individual microconstituents under mild conditions such as low temperature and aqueous solutions of ethanol. The solvation of the microparticles and the microparticle-assembled structures are key factors for controlling the disassembly of microparticle-based polymers without performing chemical reactions.

The radiological accidents that occurred at the Chernobyl and Fukushima Daiichi nuclear power plants resulted in the release of a substantial amount of radioactive material into the environment, requiring evacuation of residents. Evacuations caused involuntary abandonment of many pets, and both feral dogs and cats can still be found in exclusion zones of Chernobyl and Fukushima, likely offspring of pets left behind. Animal welfare groups have provided care for these forsaken animals, oftentimes rescuing them and subsequently facilitating their adoption, or in some cases reuniting them with their original owners.

Aneuploidy in oocytes is a leading cause of implantation failure, miscarriage and congenital disorders. During meiosis, proper timing of chromosome segregation is regulated by the spindle assembly checkpoint (SAC) and the anaphase-promoting complex/cyclosome (APC/C). However, how pharmacological manipulation of these regulatory pathways affects aneuploidy remains incompletely understood.

Microautophagy is an intracellular degradation process in which degradatory organelles, such as the lysosome, directly take up substrates by invagination and/or protrusion of their membranes. Here, we provide evidence that Rab32-positive, lysosome-related organelles in macrophages incorporate various other organelles, including endosomes and mitochondria. Our data indicates that, upon exposure to a mitochondria-damaging reagent, mitochondria can be directly engulfed by the lysosome-like organelles independently of macroautophagy or ESCRT machinery.

The half-sitting posture is essential for many functional tasks performed by industrial workers. Thus, passive lower-limb exoskeletons, known as wearable chairs, are increasingly used to relieve lower-limb loading in such scenarios. However, although these devices lighten muscle effort during half-sitting tasks, they can disrupt walking mechanics and balance.

Despite being the most common adult heart valve disease in developed countries, no medicinal treatment exists for calcific aortic valve stenosis (CAS). We previously demonstrated that tumor necrosis factor (TNF)-α promotes aortic valve calcification (AVC) via the bone morphogenic protein (BMP) 2-alkaline phosphatase (ALP) pathway. In the present study, we aimed to investigate the effects of Kampo, a traditional Japanese herbal medicine, on TNF-α-induced AVC involving CAS progression.

Cervical cancer comprises squamous cell carcinomas (SCCs), which are generally radiosensitive; meanwhile, adenocarcinomas respond poorly to radiation. Here, we explored the role of selective autophagy receptors in modulating radiosensitivity across these subtypes. We found that SQSTM1/p62 was highly expressed in human papillomavirus (HPV)-positive SCC cell lines (HeLa, ME180) and clinical SCC specimens, but was low or undetectable in HPV-negative adenocarcinomas and the C33A cell line.
