Researchers discover specific cellular pathway involved in lung tissue regeneration

Researchers at Children's Hospital of Philadelphia and the Perelman School of Medicine at the University of Pennsylvania have identified a cellular pathway that can be targeted with a naturally occurring drug to stimulate lung tissue regeneration, which is necessary for recovery from multiple lung injuries.

Brain wiring genes may be linked to a significant portion of cerebral palsy cases

In an article published in Nature Genetics, researchers confirm that about 14% of all cases of cerebral palsy, a disabling brain disorder for which there are no cures, may be linked to a patient's genes and suggest that many of those genes control how brain circuits become wired during early development.

New mechanism that prevents hair loss identified

A team of researchers from Cologne and Helsinki has discovered a mechanism that prevents hair loss: hair follicle stem cells, essential for hair to regrow, can prolong their life by switching their metabolic state in response to low oxygen concentration in the tissue.

Marrowquant can quantify multiple bone components in histological images

The bone marrow is the soft tissue inside our bones. Its main role is to produce stem cells that will go on to become various cells of the blood, including white blood cells that fight infections, red blood cells that carry oxygen throughout the body, and platelets that control bleeding.

Risk factors for mortality among hospitalized patients with COVID-19

A new study by scientists at biotechnology company Genentech, Inc., and published on the preprint server medRxiv in September 2020 attempts to identify the factors which may shape the risk for death in COVID-19 disease.

ECMO appears to be saving the lives of many critically ill COVID-19 patients

It saved lives in past epidemics of lung-damaging viruses. Now, the life-support option known as ECMO appears to be doing the same for many of the critically ill COVID-19 patients who receive it, according to a new international study.

Pitt team receives NIH award to optimize tissue-engineered vascular graft design

Just as a climbing plant needs the right trellis to thrive, a small-diameter tissue-engineered vascular graft (TEVG) needs the right scaffold to transform seeded cells into a native-like artery that can save a life.

Researchers solve the mystery of how giant molecular proton pump works

Mitochondria are the powerhouses of our cells, generating energy that supports life. A giant molecular proton pump, called complex I, is crucial: It sets in motion a chain of reactions, creating a proton gradient that powers the generation of ATP, the cell's fuel.

Men with COVID-19 have worse outcomes than women, confirms study

New research presented at this week's ESCMID Conference on Coronavirus Disease (ECCVID, online 23-25 September) confirms that men with COVID-19 have worse outcomes than women, possibly related to them experiencing higher levels of inflammation.

Researchers develop 'Trojan horse' approach to destroy cancer cells

Cancer cells are killed in lab experiments and tumour growth reduced in mice, using a new approach that turns a nanoparticle into a 'Trojan horse' that causes cancer cells to self-destruct, a research team at the Nanyang Technological University, Singapore (NTU Singapore) has found.
