Despite notable advances in anticancer drug development, their manufacture and use pose environmental and health risks due to toxic byproducts, drug residue contamination, and cytotoxicity to normal cells. Therefore, developing cost-effective anticancer treatments with fewer toxic side effects and higher selectivity is essential to the advancement of highly effective anticancer therapies. Plasma-activated water (PAW) offers a green alternative to conventional chemical treatments as it reverts to water within days.

A 36-year-old man with Marfan syndrome underwent mitral surgery after personalized external aortic root support operation. Redo surgery was performed without aortic cannulation (with right axillary cannulation and retrograde cardioplegia). Surgical findings revealed unique aortic changes with adventitial growth and vasa vasorum, without visible mesh.

Article Synopsis
  • Heat-resistant fungal conidia, particularly Aspergillus tubingensis and Aspergillus flavus, are problematic contaminants in wheat grain spawn despite standard sterilization techniques like heating.
  • The study explored alternative sterilization methods using NaOCl (sodium hypochlorite) and cold plasma, analyzing their effectiveness through various spectroscopy techniques and microscopy.
  • Results indicated that these methods could significantly reduce conidia size and contamination, potentially shortening sterilization time for wheat spawn production to just 30 seconds.

Dorsal root ganglion (DRG) toxicity has been consistently reported as a potential safety concern after delivery of adeno-associated viruses (AAVs) containing gene-replacement vectors but has yet to be reported for RNAi-based vectors. Here, we report DRG toxicity after AAV intra-CSF delivery of an RNAi expression construct-artificial microRNA targeting superoxide dismutase 1 (SOD1)-in non-human primates (NHPs) and provide evidence that this can be recapitulated within mice. Histopathology evaluation showed that NHPs and mice develop DRG toxicity after AAV delivery, including DRG neuron degeneration and necrosis and nerve-fiber degeneration that were associated with increases in cerebrospinal fluid (CSF) and serum phosphorylated neurofilament heavy chain (pNF-H).

Plasma bubble (PB) is a promising technology to control antibiotic wastewater pollution. However, the practical implementation of PB technology at the industrial-scale is still underdeveloped. In addition, the influence of different discharge modes for PB on wastewater treatment is largely unknown.
