Novel nanoparticle drug delivery system for enhanced tumor penetration of cancer drugs

For more than a decade, biomedical researchers have been looking for better ways to deliver cancer-killing medication directly to tumors in the body. Tiny capsules, called nanoparticles, are now being used to transport chemotherapy medicine through the bloodstream, to the doorstep of cancerous tumors.

Researchers develop new technique to study blood vessel inflammation

Nanotechnology has led to better diagnostic techniques and more effective treatments for a variety of illnesses. Tiny devices measuring between 1 and 100 micrometers--one micrometer is equal to one millionth of a meter--enable scientists to observe cell activity and deliver drugs to individual cells--a breakthrough that is on the verge of revolutionizing precision medicine for treatment of diseases such as cancer.

Researchers demonstrate novel method for imaging engineered nanoparticles in tissues

As a testament to Governor Andrew Cuomo’s leadership in developing an unparalleled research and development ecosystem in New York State, Sara Brenner, MD, MPH and her colleagues at SUNY Polytechnic Institute (SUNY Poly), the George Washington School of Medicine and Health Sciences, and Stony Brook University have demonstrated a novel method for the rapid visualization and identification of engineered nanoparticles in tissues.

Microneedle-embedded patch delivers cancer immunotherapy directly to melanoma

Biomedical engineering researchers at North Carolina State University and the University of North Carolina at Chapel Hill have developed a technique that uses a patch embedded with microneedles to deliver cancer immunotherapy treatment directly to the site of melanoma skin cancer. In animal studies, the technique more effectively targeted melanoma than other immunotherapy treatments.

Researchers develop unique approach to track, label neural stem cells

An overwhelming number of researchers still struggle within the black hole of the effectiveness and safety of stem cell therapy for neurological diseases. While the complexity of understanding how neurons grow, connect and function has long been studied, it remains a mystery, one that graduate student Forrest Goodfellow in the University of Georgia Regenerative Bioscience Center is helping unravel.

Novel plasmid-based microRNA inhibitor system effectively prevents microRNA activity in cells

Today at the 45th Annual Meeting & Exhibition of the American Association for Dental Research, researcher Brad Amendt, University of Iowa, Iowa City, USA, will present a study titled "New Biotechnology to Inhibit MicroRNA Activity and Novel Applications for Craniofacial and Dental Research."

Research confirms potential use of iron oxide nanoparticles in biomedical applications

Iron oxides are widespread in nature and can be readily synthesized in the laboratory. Among them, hematite, magnetite and maghemite nanoparticles have particularly promising properties for biomedical applications.

Theoretical modelling helps to understand interior structures of cubosomes

Under certain conditions appropriately selected particles can form closed surfaces in liquids with surprisingly complex shapes, cutting through space by a regular network of channels. So far, we have looked at cubosomes - for this is what these spectacular three-dimensional nanostructures are called - only from the outside.

New drug could transform treatment of metastatic triple negative breast cancer

A team of investigators from Houston Methodist Research Institute may have transformed the treatment of metastatic triple negative breast cancer by creating the first drug to successfully eliminate lung metastases in mice.

Synthetic nanoparticle can light up and treat atherosclerotic plaques

Atherosclerosis, a disease in which plaque builds up inside arteries, is a prolific and invisible killer, but it may soon lose its ability to hide in the body and wreak havoc. Scientists have now developed a nanoparticle that functionally mimics nature's own high-density lipoprotein (HDL). The nanoparticle can simultaneously light up and treat atherosclerotic plaques that clog arteries. Therapy with this approach could someday help prevent deadly heart attacks and strokes.

Delivering microRNAs in cancer treatment: an interview with Dr Conde and Prof Artzi

microRNAs (miRs) are small endogenous noncoding RNA molecules (20–23 nucleotides) derived from imperfectly paired hairpin RNA structures naturally encoded in the genome that act specifically as triggering molecules to control translational repression or mRNA degradation.

Novel nanoparticle technology can decipher protein structures and help access drug targets

Researchers at Karolinska Institutet, Sweden, have developed a nanoparticle technology that can be used to stabilise membrane proteins so that their structure can be studied in a lipid environment. The method, described in Nature Methods, makes it possible to access drug targets that previously could not be investigated and therefore potentially allows for the development of novel drugs, therapeutic antibodies and vaccines.

Drug-incorporated nanoparticle platforms allow for selective targeting of cancer cells

Cancer is a group of diseases characterized by the uncontrolled growth and spread of abnormal cells. It is a leading cause of death and the burden is expected to grow worldwide due to the growth and aging of the population, mainly in less developed countries, in which about 82% of the world's population resides. By 2030, the global burden is expected to grow to 21.7 million new cancer cases and 13 million cancer deaths simply due to the growth and aging of the population. Current cancer therapy approaches are based in surgery, radiotherapy and chemotherapy, being the chemotherapy the one that shows the greater efficiency for cancer treatment, mainly in more advanced stages. A major problem with this conventional chemotherapy is its toxicity and it also destroys healthy tissues resulting in systemic toxicity besides beneficial characteristics of killing cancer cells. Anticancer drugs also destroy healthy tissues resulting in systemic toxicity.

Researchers aim to develop gentler treatment that 'tricks' cancer cells

The most common treatments for cancer are radiation and chemotherapy. However they have side effects and also damage healthy tissues. Moreover, their effectiveness is limited when the cancer has spread through out the body. Researchers at the Niels Bohr Institute are therefore working to develop a gentler treatment that 'tricks' the cancer cells, which would absorb a cytotoxin and therefore be destroyed, while healthy cells would remain unaffected. The results are published in the scientific journal, Scientific Reports.
