An international science team has developed an innovative therapeutic complex based on multi-layer polymer nano-structures of superoxide dismutase (SOD). The new substance can be used to effectively rehabilitate patients after acute spinal injuries, strokes, and heart attacks.
Published in Nature Cell Biology (NCB), the study shows that the EXD2 protein is critical for the mitochondria, the cell's powerhouses, to produce energy. This protein was previously thought to be located in the cell nucleus and to be involved in DNA repair. The results contribute to our basic understanding of mitochondria and suggest that EXD2 could be important for fertility and represent a potential target for cancer therapy.
A new study has shown that a fully 3-D-printed whisker sensor made of polyurethane, graphene, and copper tape can detect underwater vortexes with very high sensitivity.
Testing new clinical drugs' effect on heart tissue could become quicker and more straightforward, thanks to new research from Harvard University. The study, published today in the journal Biofabrication, sets out a new, faster method for manufacturing a 'heart-on-a-chip,' which can be used to test the reaction of heart tissue to external stimuli.
Genomes of single microbial cells isolated from the Red Sea could yield a goldmine for biotechnology.
Shale gas is one of least sustainable options for producing electricity, according to new research from The University of Manchester.
Using a unique technology called 'cell quake elastography,' scientists can now map to the millisecond the elasticity of components vibrating inside a cell. This discovery published in PNAS this week by Guy Cloutier and his team from CRCHUM, Université de Montréal and INSERM, opens up a whole new field of research in mechanobiology, opening the door to many practical applications in medicine.
An international team of researchers has revealed a fundamental mechanism responsible for handling stress in staphylococci when they are exposed to antibiotics. It is expected that the research results eventually can be used to develop new antibiotics that circumvent such stress mechanisms.
Wearable biosensors have grown increasingly popular as many people use them in wristbands or watches to count steps or track sleep. But there is not enough proof that these devices are improving patient outcomes such as weight or blood pressure, according to a study by Cedars-Sinai investigators published in the new Nature Partner Journal, npj Digital Medicine.
In the fight to cure thromboinflammatory diseases, one of the target molecules is thrombin, a protein that promotes inflammation and can cause blood clots. However, inhibiting thrombin too much can lead to uncontrolled bleeding, limiting the use of anti-inflammatory drugs. Now, researchers from BIDMC and the Wyss Institute have found that a class of small molecule called 'parmodulins' can reduce inflammation without compromising normal blood clotting, making parmodulins attractive candidates for new, safer drugs.
