Turbulence Connection for Dialysis

Authors: George Rajna

Patients with kidney failure often require arteriovenous grafts to be connected to dialysis machines for their lifesaving treatment. [43] Photodynamic therapy (PDT) uses light to destroy tumours by activating a photosensitive drug that creates reactive oxygen species that attack cancer cells. [42] A research team from the UK and Sweden has used dynamic flortaucipir-PET imaging to show that single moderate-to-severe traumatic brain injury (TBI) can trigger signs of accumulation of neurodegenerative tau protein and lead to cognitive decline. [41] The nonviral, bioinspired gene delivery method developed by researchers at RMIT University has proven effective in laboratory tests and is safer than standard viral approaches. [40] Now, researchers reporting in ACS' Nano Letters have engineered genetically encoded protein crystals that can generate magnetic forces many times stronger than those already reported. [39] A unique new flexible and stretchable device, worn against the skin and capable of producing electrical energy by transforming the compounds present in sweat, was recently developed and patented by CNRS researchers from l"Université Grenoble Alpes and the University of San Diego (U.S.). [38] Michigan State University scientists have invented a new way to monitor chemotherapy concentrations, which is more effective in keeping patients' treatments within the crucial therapeutic window. [37] Nanotechnology developed at Rutgers University-New Brunswick could boost research on stem cell transplantation, which may help people with Alzheimer's disease, Parkinson's disease, other neurodegenerative diseases and central nervous system injuries. [36] Tiny silica bottles filled with medicine and a special temperature-sensitive material could be used for drug delivery to kill malignant cells only in certain parts of the body, according to a study published recently by researchers at the Georgia Institute of Technology. [35] The lab of Cheryl Kerfeld at Michigan State University has created a synthetic nano-sized factory, based on natural ones found in bacteria. [34]
