Researchers Use a Molecular Trojan Horse to Deliver Chemotherapeutic Drug to Cancer Cells

A research team at the University of California, Riverside has discovered a way for chemotherapy drug paclitaxel to target migrating, or circulating, cancer cells, which are responsible for the development of tumor metastases. Until now, paclitaxel has only been used to target rapidly dividing cancer cells. The team was successful […]

Frailty a bigger predictor of post-surgery outcomes than age

Being frail or vulnerable were stronger predictors of post-operative outcomes than age, according to a comprehensive study by University of Alberta researchers. “One-third of patients 65-plus who underwent emergency abdominal surgery were either readmitted to hospital or died six months later. That high number alone surprised us,” said Rachel Khadaroo, a […]

Steep U.S. increase projected for rare skin cancer

The number of U.S. cases of Merkel cell carcinoma, an often-fatal skin cancer, is rising about six times faster than most other cancers and at nearly twice the rate of the more-common melanoma. The Journal of the American Academy of Dermatology's March issue reports the finding, which is based on research conducted at the […]

Two in one: human placenta stem cells hold a dual benefit

Scientists have discovered a new type of stem cell which has the potential to perform two functions at the same time, meaning better treatment or even cures for many diseases. University of Queensland researchers have found that Meso-Endothelial stem cells in the placenta can generate two cell types and therefore one cell has […]

Proteins that package DNA participate in DNA repair

Proteins that function like spools to tightly wind DNA, called histones, play an active role in DNA repair, according to a new study from Weill Cornell Medicine scientists. The study, published in the journal Molecular Cell, provides the first evidence that histones exist on single strands of DNA and unveils […]

Stem-cell based stroke treatment repairs brain tissue

A team of researchers at the University of Georgia’s Regenerative Bioscience Center and ArunA Biomedical, a UGA startup company, have developed a new treatment for stroke that reduces brain damage and accelerates the brain’s natural healing tendencies in animal models. They published their findings in the journal Translational Stroke Research. The research team […]

Data Detectives Shift Suspicions in Alzheimer's from Usual Suspect to Inside Villain

The mass pursuit of a conspicuous suspect in Alzheimer’s disease may have encumbered research success for decades. Now, a new data analysis that has untangled evidence amassed in years of Alzheimer’s studies encourages researchers to refocus their investigations. Heaps of plaque formed from amyloid-beta that accumulate in afflicted brains are what stick […]

New Technique Predicts Gene Resistance to Cancer Treatments

Yale School of Public Health researchers have developed a new method to predict likely resistance paths to cancer therapeutics, and a methodology to apply it to one of the most frequent cancer-causing genes.  That gene, KRAS, is mutated in approximately 20 percent of all human cancers and has a major […]

UCI cracks code to restoring memory creation in older or damaged brains

Aging or impaired brains can once again form lasting memories if an enzyme that applies the brakes too hard on a key gene is lifted, according to University of California, Irvine neurobiologists. “What we’ve discovered is that if we free up that DNA again, now the aging brain can form […]

National study to shed light on aging

Imagine getting a phone call asking if you’d like to take part in a study … for the next 20 years. It’s a pitch that makes telemarketing look like child’s play. So no wonder Christina Wolfson, BSc’76, MSc’78, PhD’85, a professor in the Faculty of Medicine, says that the recruitment of […]

Living human tracheas

Biomedical engineers at Case Western Reserve University are growing tracheas by coaxing cells to form three distinct tissue types after assembling them into a tube structure—without relying on scaffolding strategies currently being investigated by other groups. Successful trials and further research and development could someday allow surgeons the option of […]

Neuroimaging reveals lasting brain deficits in iron-deficient piglets

Iron deficiency in the first four weeks of a piglet’s life – equivalent to roughly four months in a human infant – impairs the development of key brain structures, scientists report. The abnormalities remain even after weeks of iron supplementation begun later in life, the researchers found. The discovery, reported in the […]

Bridging tumor moats with potent drug delivery particles

Despite herculean efforts, cancer remains a formidable disease, with each malignant subtype responding differently to therapeutics. One hurdle specific to treating solid tumors is a protective layer called an extracellular matrix that can prevent chemotherapeutic agents from penetrating the tumor’s core. Scientists now report results in ACS’ Chemistry of Materials showing that, […]

Asthma medication linked to infertility in women

Women with asthma who only use short-acting asthma relievers take longer to become pregnant than other women, according to international research led by the University of Adelaide. However, the study of more than 5600 women in Australia, New Zealand, the United Kingdom and Ireland also shows that women with asthma […]

Cells ‘walk’ on liquids a bit like geckos

Cells are typically grown on solid materials, such as tissue culture plastic, degradable polymers and bioceramics. It is thought that the strong mechanical properties of these biomaterials are required to allow cell adhesion, an important process often controlling the behaviour of stem cells and promoting implant incorporation by surrounding tissues […]
