Materials resulting from chemical bonding of glucosamine, a type of sugar, with fullerenes, kind of nanoparticles known as buckyballs, might help to reduce cell damage and inflammation occurring after stroke. A team from the Max Planck Institute in Germany has tested this on mice, opening the door to potential new drugs for the cerebrovascular accident.
Treating respiratory disease is often difficult because drugs have to cross biological barriers such as respiratory tissue and mucosa, and must therefore be given in large quantities in order for an effective amount to reach the target. Now researchers from Germany, Brazil and France have shown that the use of nanoparticles to carry antibiotics across biological barriers can be effective in treating lung infections.
Dental diseases, which are caused by the overgrowth of certain bacteria in the mouth, are among the most common health problems in the world. Now scientists have discovered that a material called graphene oxide is effective at eliminating these bacteria, some of which have developed antibiotic resistance. They report the findings in the journal ACS Applied Materials & Interfaces.
Tekmira Pharmaceuticals Corporation, an industry-leading therapeutic solutions company focused on developing a cure for chronic hepatitis B virus infection (HBV), announced today that TKM-Ebola-Guinea will be evaluated for efficacy in Ebola virus infected patients in Sierra Leone, West Africa. Patient recruitment has been initiated.
When UC Berkeley bioengineers say they are holding their hearts in the palms of their hands, they are not talking about emotional vulnerability.
Light long has been used to treat cancer. But phototherapy is only effective where light easily can reach, limiting its use to cancers of the skin and in areas accessible with an endoscope, such as the gastrointestinal tract.
Particle Sciences, Inc (PSI), the leading CDMO for micro and nano-particulates is expanding its sterile and aseptic manufacturing capacity generally and specifically for nano-milled drug products. According to Mark Mitchnick, CEO at Particle Sciences, "In 2014 we initiated a record number of projects that are headed into the clinic with over 50% of those being sterile and 50% of those requiring aseptic processing.
There are about 48,000 corneal transplants done each year in the U.S., compared to approximately 16,000 kidney transplants and 2,100 heart transplants[1] [2]. Out of the 48,000 corneal transplants done, 10 percent of them end up in rejection, largely due to poor medication compliance. This costs the health care system and puts undue strain on clinicians, patients and their families.
To develop a device based on nanophotonic technology that enables a quick and early diagnosis of different types of cancer –specifically breast, prostate, lung and colorectal– analysing only two or three drops of blood. This is the objective of SAPHELY, a European project funded by the EU's Horizon 2020 programme, led by the Valencia Nanophotonics Technology Center of the Universitat Politècnica de València. The SYM group of Centre for Molecular Recognition and Technological Development is also participating in the project as the second partner from the UPV.
Infection with highly contagious noroviruses, while not usually fatal, can lead to a slew of unpleasant symptoms such as excessive vomiting and diarrhea. Current treatment options are limited to rehydration of the patient. "Additionally, noroviruses come in a variety of constantly evolving strains. This makes the development of an effective vaccine to protect against infection, as well as antiviral therapy to combat already-existing infections, particularly challenging", says Dr. Grant Hansman, a virologist who leads the CHS Research Group on Noroviruses at the German Cancer Research Center (Deutsches Krebsforschungszentrum, DKFZ) and Heidelberg University.
