Vanderbilt University researchers have joined a multi-center effort led by Pennsylvania-based Inovio Pharmaceuticals Inc. to accelerate development of potential antibody therapies against the often-lethal Ebola virus. On Wednesday, Inovio announced it had been awarded an initial two-year, $21-million grant from the Defense Advanced Research Projects Agency (DARPA), part of the US Department of Defense, to […]

Cigarette Smoke Makes Superbugs More Aggressive

Methicillin-resistant Staphylococcus aureus (MRSA), an antibiotic-resistant superbug, can cause life-threatening skin, bloodstream and surgical site infections or pneumonia. Researchers at the University of California, San Diego School of Medicine now report that cigarette smoke may make matters worse. The study, published by Infection and Immunity, shows that MRSA bacteria exposed to cigarette smoke become even […]

Dartmouth Investigators Develop Antibacterial Enzymes To Combat Drug-Resistant Bacterial Pathogens

The fluorescent micrograph shows gel microdroplets containing bacterial target cells (small black clusters) or bacterial cells co-encapsulated with GFP labeled yeast (larger green cells). Yeast secreting active bacteriolytic enzymes kill co-encapsulated bacteria resulting in orange fluorescent staining with the SYTOX viability probe.

By engineering antibacterial enzymes, Dartmouth investigators led by Karl Griswold, PhD are using novel strategies to target the prevalent drug-resistant bacterium Staphylococcus aureus. Recent papers in FEMS Microbiology Letters and Applied Microbiology and Biotechnology describe their findings from a genome mining effort seeking novel antibacterial agents. A third paper published in ACS Chemical Biology examines […]

One Dollar Blood Test Using Gold Nanoparticles Outperforms PSA Screen For Prostate Cancer, Study Suggests

Dr. Qun "Treen" Huo of UCF's NanoScience Technology Center has developed a prostate cancer test using gold nanoparticles. Pilot studies found it to be more accurate than the standard PSA test.

A test that costs less than a $1 and yields results in minutes has been shown in newly published studies to be more sensitive and more exact than the current standard test for early-stage prostate cancer. The simple test developed by University of Central Florida scientist Qun “Treen” Huo holds the promise of earlier detection […]

‘Lab-On-A-Disc’ Diagnoses Infectious Diseases At The Point-Of-Care

A new ‘lab-on-a-disc’ technology developed by an EU project research team can diagnose malaria and other febrile infectious diseases simultaneously in just an hour – allowing faster point-of-care treatment and precise drugs administration that could save thousands of lives. A major problem with current testing for infectious diseases in Africa is that it focuses on […]
