by Ten Bridge Communications Senolytics are an emerging class of investigational drug compounds that selectively kill aging-associated senescent cells (left, with red stain) without affecting other cells (right). Using artificial intelligence, researchers from Integrated Biosciences have, for the first time, identified three senolytics with comparable efficacy and superior drug-like properties relative to leading investigational compounds....
Clinically relevant deficiency of the “bonding hormone” oxytocin demonstrated
Peer-Reviewed Publication UNIVERSITY OF BASEL The hormone oxytocin is important for social interaction and to control emotions. A deficiency of this hormone has previously been assumed in various diseases such as autism, but has never been proven. Now, for the first time, researchers from the University of Basel and the University Hospital of Basel have...

A self-administered mobile app to detect Alzheimer’s disease using speech data
by University of Tsukuba Credit: Sergey Nivens/Shutterstock Alzheimer’s disease (AD) is the most common form of dementia. It is important to start intervention from an early stage, e.g., the mild cognitive impairment (MCI) stage, to prevent or delay the progression of AD. For the early detection of AD and MCI, there is a growing need to...
Women with hardened arteries may need stronger treatment to prevent heart attacks than men
EUROPEAN SOCIETY OF CARDIOLOGY Barcelona, Spain – 11 May 2023: Postmenopausal women with clogged arteries are at higher risk of heart attacks than men of similar age, according to research presented at EACVI 2023, a scientific congress of the European Society of Cardiology (ESC),1 and published in European Heart Journal – Cardiovascular Imaging.2 The study in nearly 25,000 adults...

‘Mini-PCNL’ surgery has higher stone-free rate in treating intermediate-size kidney stones, finds randomized trial
by Wolters Kluwer Health Graphical abstract. Credit: Journal of Urology (2023). DOI: 10.1097/JU.0000000000003397 For patients with kidney stones measuring one to two centimeters, a technique called mini-percutaneous nephrolithotomy (mini-PCNL) provides a higher stone elimination rate than another minimally invasive procedure called ureteroscopy (URS), concludes a randomized trial in the Journal of Urology. “In our clinical trial, mini-PCNL was more likely to...
