Researchers determine differences in stiffness between healthy and cancerous tissue

The texture of breast cancer tissue differs from that of healthy tissue. Using a cutting-edge tissue diagnostic device, a group of researchers in Basel, Switzerland, has determined one key difference: cancerous tissue is a mix of stiff and soft zones, whereas healthy tissue has uniform stiffness.

TB test offers rapid detection of TB and drug-resistant strains according to new study

A diagnostic test for tuberculosis (TB) can accurately and quickly detect both TB and drug-resistant strains, according to a new study. The authors of a new systematic review assessing the diagnostic accuracy of the Xpert® MTB/RIF test published in The Cochrane Library say their study can provide timely advice for clinicians and policymakers in countries where TB is a major public health problem.

Vaccine confidence: an interview with Dr Heidi Larson

Here at the London School of Hygiene and Tropical Medicine we are running a project called the Vaccine Confidence Project and we have a global surveillance monitoring information around the world on media, social media, all sorts of information, reports from governments, UN, other sources, looking for any what we call “signals” of public distrust or concerns that come up.

One-step, off-the-shelf tool can help evaluate genetic cause of mitochondrial diseases

More powerful gene-sequencing tools have increasingly been uncovering disease secrets in DNA within the cell nucleus. Now a research team is expanding those rapid next-generation sequencing tests to analyze a separate source of DNA—within the genes inside mitochondria, cellular power plants that, when abnormal, contribute to complex, multisystem diseases.

Colorectal cancer screening: an interview with Dr Donato F. Altomare

Colorectal cancer is a malignant neoplasm affecting the large bowel and the rectum mainly after the 5th decade of life and representing the second cause of death for cancer in western countries (the third in women). In about 15-20% of patients there is an inherited predisposition.

Scientists discover four processes by which gastric cancer is formed

Scientists at A*STAR's Genome Institute of Singapore (GIS) headed a study that discovered four processes by which gastric cancer is formed. This is extremely important since gastric cancer is the second most common cause of cancer deaths worldwide, claiming almost 750,000 lives annually, 60% of which are Asians.

Researchers identify cancer-associated mutations

Two new mutations that collectively occur in 71 percent of malignant melanoma tumors have been discovered in what scientists call the "dark matter" of the cancer genome, where cancer-related mutations haven't been previously found.

Subsidised antimalarial drugs: an interview with Kara Hanson

Artemisinin-based combination therapies (ACTs) are the currently recommended drugs for treating malaria. However, they are expensive, which limits their affordability. This means that people with malaria are likely to buy cheaper, less effective antimalarials such as chloroquine and sulphadoxine-pyrimethamine; or to simply buy painkillers and antipyretics.

New handheld device performs rapid HIV tests

Samuel K. Sia, associate professor of biomedical engineering at Columbia Engineering, has taken his innovative lab-on-a-chip and developed a way to not only check a patient's HIV status anywhere in the world with just a finger prick, but also synchronize the results automatically and instantaneously with central health-care records-10 times faster, the researchers say, than the benchtop ELISA, a broadly used diagnostic technique.

Clinical trial to evaluate cyclodextrin against Niemann-Pick disease type C1

A clinical trial to evaluate a drug candidate called cyclodextrin as a possible treatment for Niemann-Pick disease type C1 (NPC), a rare and fatal genetic disease, will start today, researchers announced.

Antibodies essential for dendritic cell maturation

Dendritic cells, or DCs for short, perform a vital role for the immune system: They engulf pathogens, break them down into their component parts, and then display the pieces on their surface.

ParseCNV software can detect disease-causing copy number variations

A novel software tool, developed at The Children's Hospital of Philadelphia, streamlines the detection of disease-causing genetic changes through more sensitive detection methods and by automatically correcting for variations that reduce the accuracy of results in conventional software.
