In this study, we tested a novel approach of "repurposing" a biomarker typically associated with breast cancer for use in melanoma. HER2/neu is a well characterized biomarker in breast cancer for which effective anti-HER2/neu therapies are readily available. We constructed a lentivirus encoding c-erb-B2, an animal (rat) homolog to HER2/neu.

Filtration membranes coated in metals such as copper have dramatically improved biofouling resistance and pathogen destruction. However, existing coating methods on polymer membranes impair membrane performance, lack uniformity, and may detach from their substrate, thus contaminating the permeate. To solve these challenges, we developed the first electroless deposition protocol to immobilize copper nanoparticles on electrospun polyacrylonitrile (PAN) fibers for the design of antimicrobial membranes.

Article Synopsis
  • - The proliferation of electronic devices has increased their susceptibility to corrosion, especially in copper traces of printed circuit boards (PCBs), highlighting limitations in traditional protective methods like conformal coatings.
  • - This study explores using cold atmospheric plasma (CAP) to apply ultrathin silicon oxide (SiO) coatings onto copper surfaces, focusing on how scanning speed affects film quality and corrosion resistance.
  • - Results showed that a scanning speed of 45 mm/s yielded a 140 nm thick coating with 30-fold better corrosion resistance than uncoated copper, demonstrating the potential of CAP coatings over traditional methods in protecting electronic components like LEDs and PCBs used in agriculture.

Intratumoral injection of anticancer agents has limited efficacy and is not routinely used for most cancers. In this study, we aimed to improve the efficacy of intratumoral chemotherapy using a novel approach comprising peri-tumoral injection of sustained-release liposomal nanoparticles containing phenylephrine, which is a potent vasoconstrictor. Using a preclinical model of melanoma, we have previously shown that systemically administered (intravenous) phenylephrine could transiently shunt blood flow to the tumor at the time of drug delivery, which in turn improved antitumor responses.
