Glial hyper-drive for triggering epileptic seizures

When epileptic patients suffer seizures, their brain is undergoing repetitive and excessive neuronal firing. But what triggers this has stumped scientists for years. Now, researchers have used fluorescence calcium sensors to track astrocytes' role in epileptic seizures, finding that that astrocyte activity starts approximately 20 seconds before the onset of epileptic neuronal hyperactivity.

Next-generation treatments hitch a ride into cancer cells

Researchers found that a new activator called L687 induces cancer cells to accept delivery of antisense oligonucleotide (ASO) drugs. These drugs can treat cancer by blocking the transfer of messages from genes that encourage cancer growth. Previous methods to deliver ASOs into cells had only limited success. This research will help accelerate the development and delivery of novel ASO cancer therapies.

AI-assisted breast-cancer screening may reduce unnecessary testing

Researchers showed that AI assistance potentially could improve breast-cancer screening by reducing the number of false positives without missing true positives.

Nasal spray safely treats recurrent abnormal heart rhythms, clinical trial suggests

A clinical trial showed that a nasal spray that patients administer at home, without a physician, successfully and safely treated recurrent episodes of a condition that causes rapid abnormal heart rhythms. The study provides real-world evidence that a wide range of patients can safely and effectively use the experimental drug, called etripamil, to treat recurrent paroxysmal supraventricular tachycardia (PSVT) episodes at home, potentially sparing them the need for repeated hospital trips for more invasive treatments.

Less extensive breast cancer surgery results in fewer swollen arms

It is possible to leave most of the lymph nodes in the armpit, even if one or two of them have metastases larger than two millimeters. This is shown in a trial enrolling women from five countries. The results open up for gentler surgery for patients with breast cancer.

'Exhausted' immune cells in healthy women could be target for breast cancer prevention

People carrying BRCA1 and BRCA2 gene mutations are at high risk of developing breast and ovarian cancer. Researchers have found that changes occur in the immune cells of breast tissue in carriers of BRCA1 and BRCA2 mutations long before breast cancer develops. This raises the possibility of early intervention to prevent the disease, as an alternative to risk-reduction surgery. Drugs already approved for late-stage breast cancer treatment could reactivate the faulty immune cells and keep the breast cells healthy. If successful in mouse models, this preventative therapeutic approach could pave the way for clinical trials in human carriers of BRCA1 and BRCA2 mutations.

Researchers develop deep learning model to predict breast cancer

Researchers have developed a new, interpretable artificial intelligence (AI) model to predict 5-year breast cancer risk from mammograms, according to a new study.
