Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Synthesis of Butyric Acid Nitrification Derivatives and Adiabatic Thermal Analysis of Reaction With Nitric Acid

He huaxue yu fangshe huaxue
Tributyl phosphate(TBP) undergoes stepwise degradation in the post-treatment system to produce butanol, which is ultimately converted into butyric acid. Butyric acid can gradually accumulate in the system and undergo nitration reactions triggered by free
