PARIS – An interdisciplinary academic research consortium in Italy has devised and tested nanowires that restore physiological cell-to-cell conductance. This research team, led by the Experimental and Applied Medical Technology Lab (Tecmed Lab) at the Department of Medicine and Surgery at the University of Parma, Italy, has just published the results of multiple local in situ injections of nanowires into left ventricular infarct regions in Nature Communications.

South Korea’s Gwangju Institute of Science and Technology (GIST) has completed a preclinical study for a noninvasive therapy for Alzheimer’s disease. The "ultrasound-based gamma entrainment” technique involves syncing up gamma waves, or brain waves above 30 Hz, with an external oscillation of a given frequency. This happens naturally by exposing a subject to a repetitive stimulus, such as sound, light, or mechanical vibrations.

A study by researchers led by David James from the University of Sydney showcases the diversity in metabolic responses observed across different mouse strains exposed to two different diets that demonstrates the heritability of metabolic traits.

A team led by researchers from the ETH Zürich and the University of Basel has used a combination of mass spectrometry data and machine learning to predict antibiotic resistance of clinical bacterial samples. The results, which were published in the Jan. 10, 2022, issue of Nature Medicine, could speed the identification of optimal antibiotic regimens for patients.

Researchers at the Peter Doherty Institute for Infection and Immunity, the University of Queensland, Griffith University, the University of Adelaide and St. Jude Children's Research Hospital have unlocked a key to making existing front-line antibiotics work again against Streptococcus pneumoniae, the bacteria that cause pneumonia.

Clinicians at the University of Maryland have transplanted a heart from a genetically modified pig bred by Revivicor Inc., a subsidiary of United Therapeutics Corp., into a patient with end-stage heart failure.

Space travel has known effects on human health and biology. Some, such as loss of bone density, are well understood, while others, like inflammation, are not. Now, organ-on-a-chip maker Emulate Inc. is conducting experiments on the International Space Station U.S. National Laboratory (ISS-NL) aimed at revealing clues to how the brain functions in microgravity.

University of California San Diego engineers have developed tiny 2D sensors that pop up to become a 3D assemblage of microscopic sensors for directly measuring the movement and speed of electrical signals inside the heart. According to nanoengineering professor Sheng Xu, the nanotechnology has enormous implications for heart doctors anxious to better diagnose and treat arrhythmia, heart attack and other diseases.

In a recent study, investigators led by Tony Tiganis at Monash University, Australia have identified that upregulation of the enzyme NOX4 (NADPH oxidase 4) boosted levels of reactive oxygen species and protected development of insulin resistance in both aged as well as obese mice.

Researchers at the University of Pennsylvania’s Perelman School of Medicine have shown how nanoparticles could be used to reduce neutrophil clumping in inflamed lungs – making them a pathway for diagnosis and treatment of acute lung inflammation (ALI) and acute respiratory distress syndrome (ARDS).
