Genetic probe flares cancer directly in the blood stream

NanoFlares light up (red clouds) individual cells if a cancer (in this study, breast cancer) biomarker (messenger RNA, blue) is detected by recognition DNA (green) molecules coated on gold nanospheres and containing a fluorescent chemical (red) reporter flare (credit: Tiffany L. Halo et al./PNAS)

The Nanoflare technology uses a genetic-based approach to detect and image live cancer cells present in the blood stream, well before these had a chance to develop into a tumor. The gene-hunting particles developed at Northwestern University might help doctors develop personalized treatments for their patients and curb cancer spread, according to the paper published in PNAS. Hunting cancer’s genes…

Scientists have found a way to prevent cancerous tumors in the prostate from spreading, effectively switching off the disease. Researchers from Bristol and Nottingham universities found that a single molecule plays a crucial role in the forming of new blood vessels, and the spread of tumors could be halted with a mere injection. A neoplasm (commonly known as a tumor) is…

Diabetes cured in mice with Blood Pressure Medication

A simple blood pressure drug can be monumental in fighting diabetes. MD Consultants

Diabetes is one of the most prevalent diseases in the developed world, with more than 29 million infected Americans; 1 in 4 doesn’t know. Currently more than 29 million people in the United States have diabetes, up from the previous estimate of 26 million in 2010, according to a report released by the Centers for Disease Control and Prevention. But…

Hepatitis C vaccine shows promise in early clinical trial

hepatitis c vaccine

An initial study has shown that a vaccine against Hep C currently in clinical trials is effective and also safe in humans. Hepatitis C is an infectious disease affecting primarily the liver, caused by the hepatitis C virus (HCV). There are some 200 million people in the world infected with the disease, and around 75-85% of people with HCV will develop…

Vaccination has been highly successful in reducing the prevalence of poliomyelitis. Routine vaccination has helped reduce the number of cases by more than 99% in 30 years. However, epidemics are still occurring, and we’re still miles away from eradicating the virus. Researchers have now identified the exact strain responsible for recent outbreaks and showed that the mutations which it underwent were so…

French scientists described the mechanism through which two HIV-infected individuals have become “spontaneously cured” of the virus, explaining that this can lead to new, novel treatments in the fight against AIDS. The “apparent spontaneous cure” has opened up previously closed doors for drug engineers, they note. “The work opens up therapeutic avenues for a cure, using or stimulating this enzyme,” they…

In 2003, Dr. Lihong V. Wang at Washington University introduced one of the most exciting technologies we’ve had the chance to see in a long while. By combining ultrasound and light absorption, Wang and colleagues developed a new method that makes multicontrast images of biological tissues several inches below the skin. Among others, this allows specialists to see cancer in action with unprecedented…

Google plans Magnetic Nanoparticle pill that detects diseases like Cancer

nanoparticles

On Tuesday, Google’s head of life sciences inside the company’s Google X research lab reported a new exciting project that involves using nanoparticles that magnetically attach to key molecules and cells in the bloodstream to detect diseases, including cancer. The particles – ingested under the form of a pill – would later be gathered, scanned and monitored through a non-invasive wearable…

According to a study from Women’s College Hospital and the Institute for Clinical Evaluative Sciences (ICES), Canada, it doesn’t matter whether you live in a rural or urban setting when it comes to heart disease – the risk if the same for both environments. The general consensus is that those living in rural areas are at a disadvantage as far…

A permanent vaccine for hookworm has passed clinical trials. The hookworm is one of the most pervasive parasites, affecting over 600 million people worldwide. The virus is also known for affecting mostly poor populations. The hookworm is a parasitic nematode (round worm) that lives in the small intestine of its host, which may be a mammal such as a dog,…
