Better, cheaper healthcare with dry blood samples

24/05/2017

A drop of blood on filter paper, allowed to dry and stored for future diagnostic purposes - considerably easier than the present-day, resource-consuming method using frozen blood samples in plastic tubes. In a new study, Uppsala researchers have successfully measured 92 different proteins in millimetre-sized circles punched out of dried samples.

Mouse teeth providing new insights into tissue regeneration

02/05/2017

Researchers hope to use stem cells to heal burns, patch damaged heart tissue, even grow kidneys and other transplantable organs from scratch. This dream edges closer to reality, but one of the enduring puzzles for stem cell researchers is how these remarkable cells know when it's time for them to expand in numbers and transform into mature, adult cells in order to renew injured or aging tissue.

Using rooster testes to learn how the body fights viruses

02/05/2017

Our bodies are constantly under siege by foreign invaders; viruses, bacteria and parasites that want to infiltrate our cells. A new study in the journal eLife sheds light on how germ cells - sperm and egg - protect themselves from these attackers so that they can pass accurate genetic information to the next generation.

Novel method to detect toxic effects of chemicals

28/04/2017

Traditional toxicological investigations performed on animals (in vivo) are expensive, time-consuming and may cause animal suffering. But research from Umeå University demonstrates that a neuronal cell model, derived from mouse, can be used to evaluate the neurotoxic effect of chemicals.

Lab on a chip designed to minimize preterm births

27/04/2017

In the United States alone, a half million babies are born preterm; worldwide, the number is an estimated 15 million. Complications associated with preterm birth are the no. 1 cause of death for children under 5, and those who live often face a range of health problems.

Fungi have enormous potential for new antibiotics

21/04/2017

Fungi are a potential goldmine for the production of pharmaceuticals. This is shown by researchers at Chalmers University of Technology, who have developed a method for finding new antibiotics from nature’s own resources. The findings – which could prove very useful in the battle against antibiotic resistance – were recently published in the journal "Nature Microbiology".

One step closer to cracking the mystery of bacterial adaptation to antibiotics

11/04/2017

An international team of researchers has proposed an explanation of the way bacteria process external signals. By identifying the detailed structure of the protein complex used by bacteria, the scientists gained insights into the ability of these microorganisms to detect even small changes in the environment and adapt to them. The research findings were published in "Scientific Reports".

Mini X-ray sensor for high-precision medical applications

04/04/2017

The ability to detect X-rays on a tiny scale paves the way for high-precision medical imaging and therapies. Such detection capabilities have been achieved by researchers from the CNRS, the University of Franche-Comté (UFC), and Aix-Marseille University (AMU), who attached an X-ray sensor to the end of an optical fiber. Their work was published in "Optics Letters".

Novel approach can reveal personalized breast cancer treatments

29/03/2017

The goal of cancer therapy is to destroy the tumor or stop it from growing and spreading to other parts of the body. Reaching toward this goal, a team of researchers from various institutions, including Baylor College of Medicine, Washington University School of Medicine in St. Louis and the Broad Institute of MIT and Harvard, has developed a new way to approach breast cancer treatment.

Detecting blood clot risk using biomarkers

17/03/2017

Cancer is one of the hardest medical conditions to overcome, and for those who do so, the battle often does not stop at remission. Many cancers predispose patients to develop blood clots, particularly patients who are diagnosed at a late stage, which often complicates their treatment and reduces survival rates.

Fighting Blindness: TSRI Scientists Bring a Key Protein into Focus

08/03/2017

Scientists from the Florida campus of The Scripps Research Institute (TSRI) have discovered how a protein called α2δ4 establishes proper vision. Their research helps explain why mutations in the gene encoding α2δ4 lead to retinal dystrophy, a disease characterized by defective color vision and night blindness.
