The prognosis for patients with acute promyelocytic leukemia (APL) has improved dramatically since the introduction of all-trans retinoic acid (ATRA) and intravenous arsenic trioxide (ATO). However, ATO administration requires daily infusions over several months, representing an onerous burden for hospitals and patients. We evaluated the bioavailability of a novel encapsulated oral ATO formulation in APL patients in first complete remission during standard-of-care consolidation.

Arsenic (As) and antimony (Sb), with analogy structure, belong to VA group in the periodic table and pose a great public concern due to their potential carcinogenicity. The speciation distribution, migration and transformation, enrichment and retention, as well as bioavailability and toxicity of As and Sb are influenced by several environmental processes on mineral surfaces, including adsorption/desorption, coordination/precipitation, and oxidation/reduction. These interfacial reactions are influenced by the crystal facet of minerals with different atomic and electronic structures.

Co-pyrolysis is an efficient approach for municipal sewage sludge (SS) treatment, facilitating the production of biochar and promoting the stabilization and removal of heavy metals, particularly when combined with chlorinated materials. This study explores the impact of pyrolysis temperatures (400 °C and 600 °C) and chlorinated additives (polyvinyl chloride (PVC) as an organic chloride source and ferric chloride (FeCl) as an inorganic chloride source) at 10% and 20% concentrations, on the yield, chemical speciation, leachability, and ecological risks of arsenic (As), chromium (Cr), and zinc (Zn) in biochar derived from SS. The results revealed that increasing the pyrolysis temperature from 400 to 600 °C significantly reduced biochar yield due to enhanced volatilization of organic components, as well as the removal of heavy metals in interaction with chlorinated materials.

Soil around mines contaminated with metal(loid) is not suitable for growing plants and it is necessary to select indigenous plants with tolerance for metal(loid) and ameliorate metal toxicity in soil using soil amendments. Therefore, the purpose of this study was to improve the soil environment to make it suitable for plant growth by treating chicken manure derived-biochar in soil contaminated with arsenic (As), cadmium (Cd), and lead (Pb). Biochar application increased soil pH and significantly reduced bioavailable As, Cd and Pb, thereby lowering toxicity in plants.

By inducing apoptosis, promoting differentiation and reducing the migration of cancer cells, arsenic has a higher therapeutic effect and lower risk of recurrence and metastasis than conventional anticancer drugs. However, the low bioavailability and adverse side effects of arsenic hinder its application in hepatocellular carcinoma (HCC). Therefore, a M1 macrophage membrane-coated nickel-arsenic/polydopamine nanocomplex (NiAsOx@P@M) was constructed to enhance the combined antitumor effects of chemotherapy and immunotherapy.
