Researchers collaborate on a 15-month case study to analyze patient’s recovery from impaired adrenocorticotropic hormone

Recently, 'Long COVID' is becoming a significant issue worldwide. It refers to a variety of symptoms that persist over an extended period after the patient has recovered from a novel coronavirus infection (COVID-19). In many cases, it is unclear what causes Long COVID symptoms, and there is insufficient information regarding recovery time.

Mice study reveals hepatic consequences of exposure to endocrine disrupting chemical mixtures

We are increasingly being exposed to endocrine-disrupting chemicals (EDCs) that interfere with the normal functioning of our hormones. Bisphenol A (BPA) and phthalates, which are widely used in consumer products including plastics, aluminum cans, pharmaceuticals, and cosmetics, are well-known EDCs.

Unique tool helps to study how the mechanical forces behind protein folding affect cancer spread

Talin is a protein that controls cellular attachment and movement, but its malfunctioning also allows cancer cells to spread. DCL1 is a tumor-suppressing protein. But scientists don't fully understand how either protein works – or what happens when they don't work the way they should.
