Some skin wounds, such as diabetic ulcers, are chronic and may never heal; others, such as burn wounds, are often large and difficult to treat, resulting in pain, infection and scarring. Researchers at the University of California, Los Angeles (UCLA), funded by the National Institutes of Health (NIH), have developed a synthetic biomaterial that fills wounds and aids in regeneration of skin cells, which ultimately improves wound healing.
Rice University researchers developing temporary implants for facial reconstruction are incorporating a unique way to deliver time-released antibiotics to ward off infection while a patient heals.
Biofilms -- formed by bacteria that stick to each other on living tissue and medical instruments, making them harder to remove -- can be tricked into dispersing with the targeted application of nanoparticles and heat, researchers have found. The University of New South Wales study, jointly led by associate professor Cyrille Boyer of the School of Chemical Engineering and deputy director of Australian Centre for NanoMedicine, appears in today's issue of Nature's open access journal Scientific Reports.
A new discovery from the University of Alberta's Faculty of Medicine & Dentistry could open the door to one day treat or prevent diseases caused by West Nile virus and Dengue virus infections. The research, published and featured in the December edition of the Journal of Virology, examines a previously unknown connection between flaviviruses--a classification of viruses that include West Nile virus, Dengue virus and tick-borne encephalitis virus--and organelles (a specialized subunit within a cell) known as peroxisomes that help coordinate the body's immune responses. Postdoctoral fellow Jaehwan You and PhD student Shangmei Hou, the lead authors on the study, found that flaviviruses induce degradation of a protein called Pex19, which is essential for the building of new peroxisomes, setting off a chain reaction that could leave the body more vulnerable to viral infection.
UW researchers working in collaboration with Kineta Inc. and the University of Texas at Galveston have shown that making a drug-like molecule to turn on innate immunity can induce genes to control infection in several -known viruses. The findings being published in the Journal of Virology Dec. 18 show promising evidence for creating a broad spectrum antiviral that can suppress a range of RNA viruses, including West Nile, dengue virus, hepatitis C, influenza A, respiratory syncytial, Nipah, Lassa and Ebola.
This report summarizes and synthesizes studies from the medical literature examining the efficacy and benefits of using germicidal UV-C light technology to enhance manual cleaning and disinfection of healthcare environmental surfaces.
Uninsured patients can be trained to safely and efficiently self-administer long-term intravenous antibiotics, UT Southwestern Medical Center physicians have found, a result that may have profound implications for patient treatment at public hospitals across the country. A four-year study compared outcomes of Parkland Memorial Hospital patients who either self-administered long-term IV antibiotics or had their long-term antibiotics administered by a healthcare worker. The study found similar or better outcomes for the group that administered their own antibiotics, a practice that is rare among hospitals.
