This paper characterises nitrogen and phosphorus wash-off processes on urban road surfaces to create fundamental knowledge to strengthen stormwater treatment design. The study outcomes confirmed that the composition of initially available nutrients in terms of their physical association with solids and chemical speciation determines the wash-off characteristics. Nitrogen and phosphorus wash-off processes are independent of land use, but there are notable differences. Nitrogen wash-off is a "source limiting" process while phosphorus wash-off is "transport limiting". Additionally, a clear separation between nitrogen and phosphorus wash-off processes based on dissolved and particulate forms confirmed that the common approach of replicating nutrients wash-off based on solids wash-off could lead to misleading outcomes particularly in the case of nitrogen. Nitrogen is present primarily in dissolved and organic form and readily removed even by low intensity rainfall events, which is an important consideration for nitrogen removal targeted treatment design. In the case of phosphorus, phosphate constitutes the primary species in wash-off for the particle size fraction <75 μm, while other species are predominant in particle size range >75 μm. This means that phosphorus removal targeted treatment design should consider both phosphorus speciation as well as particle size.

Esophageal cancer (EC) is one of the most common highly malignant tumors of the digestive system, with a poor prognosis under current treatment regimens. Nucleolin (NCL) is overexpressed in many tumors, and drugs specifically targeting NCL may offer a promising strategy for treating esophageal cancer. Here, we designed and prepared a novel aptamer-conjugated drug targeting NCL by AS1411 aptamer-human serum albumin (HSA)-the apoprotein of lidamycin (LDP)-active enediyne chromophore (AE), in order to achieve targeted treatment of esophageal cancer.

Background: Oxygen therapy is critical and vital treatment for hypoxemia and respiratory distress, however, access to reliable oxygen systems remains limited in SSA. Despite WHO initiatives that distributed over 30,000 OC oxygen concentrators worldwide, SSA faces significant challenges related to their maintenance and use, due to harsh environmental conditions, technical skill shortages and inadequate infrastructure. This review aims to systematically identify and assess the literature on OC design adaptations, maintenance challenges, and knowledge gaps in SSA, providing actionable recommendations to inform innovative and context-sensitive solutions to improve healthcare delivery in the region.

Department of Hematology, University Medical Center Utrecht, Utrecht University, Utrecht, The Netherlands.
Background: Dexrazoxane has been studied for its ability to prevent anthracycline-induced cardiac dysfunction (AICD) in several trials but its use in clinical practice remains limited. This is related to the low to moderate quality of the generated evidence, safety concerns and restricted prescribing indications. Additional randomized trials are needed before this drug can be routinely integrated into cardio-oncology clinical practice.
