Scientists introduce microfluidics-based chip for manipulation and analysis of single cells

A few little cells that are different from the rest can have a big effect. For example, individual cancer cells may be resistant to a specific chemotherapy--causing a relapse in a patient who would otherwise be cured. In the journal Angewandte Chemie, scientists have now introduced a microfluidics-based chip for the manipulation and subsequent nucleic-acid analysis of individual cells.

New technique detects, measures, analyzes unevenly charged biomolecules

In clinical diagnostics, it is critical to monitor biomolecules in a simple, rapid and sensitive way. Clinicians most often monitor antibodies because these small proteins attach to antigens, or foreign substances, we face every day.

Researchers describe link between poor oocyte development and oxidative stress in obese mice

Excessive body fat is associated with negative effects on female fertility and pregnancy. In mice, maternal obesity impairs proper development of egg precursor cells called oocytes.

Experts advise against universal genomic screening of newborns

In a new report, experts at The Hastings Center advise against genomic screening of newborns, despite it's potential for providing life long personalized care.

Scientists uncover key control mechanism of DNA replication

Researchers from Osaka University in Japan have uncovered a key control mechanism of DNA replication with potential implications for better understanding how cells maintain genetic information to prevent diseases or cancer.

Researchers develop molecular matrix that delivers healing stem cells to injured elderly muscles

A car accident leaves an aging patient with severe muscle injuries that won't heal. Treatment with muscle stem cells from a donor might restore damaged tissue, but doctors are unable to deliver them effectively. A new method may help change this.

Study reveals role of RUNX proteins in DNA repair

A study by researchers from the Cancer Science Institute of Singapore at the National University of Singapore has revealed that RUNX proteins are integral to efficient DNA repair via the Fanconi Anemia pathway.

Researchers discover new promising target point for cancer and diabetes therapies

If certain signaling cascades are misregulated, diseases like cancer, obesity and diabetes may occur. A mechanism recently discovered by scientists at the Leibniz-Forschungsinstitut für Molekulare Pharmakologie in Berlin and at the University of Geneva has a crucial influence on such signaling cascades and may be an important key for the future development of therapies against these diseases.

Researchers move closer to finding potential soft spot in drug-resistant tuberculosis

Antibiotic-resistant tuberculosis is a public health threat. TB and other bacteria become resistant to antibiotics by evolving genetic changes over time, which they can do quite quickly because bacterial lifecycles are short.

Brown University researchers reveal key physical properties of 'giant' cancer cells

Polyploidal cancer cells--cells that have more than two copies of each chromosome--are much larger than most other cancer cells, are resistant to chemotherapy and radiation treatments and are associated with disease relapse.

New test predicts the risk of serious disease months before symptoms appear

Researchers have developed a new genetic test that can identify people who are at an increased risk of serious disease, long before they develop any symptoms.

Scientists define key binding characteristics of protein associated with heart disease and breast cancer

Galectins attach to other proteins via the carbohydrates on their surfaces (sugar-binding proteins). As such they impact on a range of processes in the cell associated with a number of diseases, including heart disease and breast cancer – the most common cancer in women worldwide, with 1.7 million new cases diagnosed in 2012 alone.
