Under the microscope, the lesions look the same, making it difficult to know which lesions to treat. In this study, published in Nature Medicine, researchers have for the first time, discovered…

Antibiotic resistance spreads rapidly between bacteria

The part of bacterial DNA that often carries antibiotic resistance is a master at moving between different types of bacteria and adapting to widely differing bacterial species, shows a study made by a research team at the University of Gothenburg in cooperation with Chalmers University of Technology. The results are published in an article in the scientific journal Nature Communications.

Imaging is undergoing massive changes

Although developments in molecular imaging still do not reach the high expectations placed upon them, the change in imaging is very obvious. Having been limited to the imaging of morphology, nowadays information on tissue characteristics, blood vessels or the metabolic behaviour of tumours provide many more insights, for example into response behaviour.

Urine protein could pave the way for new prostate cancer test

Scientists from the Cancer Research UK Cambridge Research Institute and The Institute of Cancer Research (ICR) built on earlier genome-wide research to link a genetic change associated with prostate cancer risk to a significant reduction in the amount of a protein called microseminoprotein-beta (MSMB). The protein - which regulates prostate cell death - is produced by normal prostate cells –…

Article • MRSA

Effective screening can kill several birds with one stone

The MRSA problem has been ignored almost stoically in many European countries for the past 20 years. Thus the number of resistant Staphylococci cases exploded from 1% in 1990 around 25% in 2010. However, the recognition that an infection can result in additional hospital costs of up to €10,000 has led to a change in thinking. The Netherlands, for example, declared war on MRSA with ‘search and…

Secret to Healing chronic wounds might lie in tiny pieces of silent RNA

Scientists have determined that chronic wounds might have trouble healing because of the actions of a tiny piece of a molecular structure in cells known as RNA. The Ohio State University researchers discovered in a new animal study that this RNA segment in wounds with limited blood flow lowers the production of a protein that is needed to encourage skin cells to grow and close over the sore.

Silenced genes as a warning sign of blood cancer

In the genetic material of cancer cells, important growth inhibitors are often switched off by chemical labels in the DNA.

New cervical smear tests are not better

France - Researchers have found new cervical smear tests to be unreliable and conclude that these should not replace conventional tests (PAP smears).

It also has implications for the regulation of medical devices and clinical practice, as well as hospital laboratory economics.
