For most people, neither polyglutamine disorders nor neuromuscular disorders are likely to be among the things they associate with androgen receptor (AR) dysfunction. But the three are indeed linked. And researchers have reported new insights into the nature of those links that could lead to a treatment for spinal and bulbar muscular atrophy, and possibly other disorders linked to AR signaling dysfunction.

PARIS – Magnetic fields can be used to stimulate blood vessel growth, according to a new study published in Science and Technology of Advanced Materials. The discovery, by researchers from the University of Lisbon in Portugal, could lead to new treatments for cancer and help regenerate tissues that have lost their blood supply.

LONDON – The latest data from the large-scale randomized U.K. COVID-19 infection survey confirm vaccines are less effective against the Delta variant of SARS-CoV-2 that is now dominant across the U.S., Europe and elsewhere in the world.

Researchers have shown that glucocorticoids, a type of steroid hormones, target both neuroplasticity-related genes and genes related to ciliary function in the brain. However, the effects on the different processes are mediated via different receptors, and in response to different stimuli. A study investigated the specific targets of glucocorticoids, giving new insights into the biological mechanisms of stress adaptations, and how they are linked to neural plasticity.

LONDON – Researchers at Birmingham University are looking for commercialization partners after finding a happy medium between the speed but limited accuracy of COVID-19 lateral flow antigen tests, and the use of slower but more accurate PCR and other RNA amplification diagnostics.

PARIS – Screenpoint Medical BV has just closed $28 million in series C funding to scale its latest generation of the Transpara system, which uses fusion AI for 2D and 3D mammography.

A less controversial option than aducanumab may be available soon to help individuals with mild to moderate Alzheimer’s disease-related dementia. Researchers at the Medical University of Vienna and the University of Toronto have developed a technique using ultrasound that reverses cognitive decline and they say it could be available for clinical use shortly.

Finding a functional cure to HIV is one of the biggest challenges in modern medicine, a task made so much tougher because of the virus’s ability to incorporate itself permanently into a host’s genome. But Diaccurate SAB, of Paris, thinks it may have a solution – and it’s all down to a discovery showing that the virus seems to make crucial immune CD4 cells go “bumpy”, lose their function and die.
