Researchers investigated the effects of mini-GRID radiotherapy on glioma cells, finding it reduced senescence and preserved growth inhibition, whereas conventional radiotherapy induced senescence. The study suggests that mini-GRID's spatial dose distribution may be responsible for this difference.
Researchers developed a novel approach to reduce neuropathic pain by targeting specific nerve cell interactions. By disrupting the interaction between voltage-gated sodium channels and ankyrin-G, they reduced pain-like behaviors in mouse models and paved the way for new therapeutics.
A new study found that the timing of Deep Brain Stimulation (DBS) surgery is critical for preserving cognitive function in Parkinson’s disease patients with a specific genetic mutation. Performing DBS within the first seven to eight years of diagnosis delays significant cognitive decline, while early intervention optimizes physical mob...
Researchers will compare brain cells from women and men with Parkinson's disease to look for biological differences that may explain sex-specific variations in the disease. The study aims to address the underrepresentation of women in Parkinson's research and advance the understanding of the disease's biological underpinnings.
Research suggests that people with dementia who are overweight or obese at diagnosis tend to live longer, pointing to the importance of nutrition in the degenerative disease. Studies adjusting for biases found no significant contribution to the observed associations between weight status and mortality.
Researchers found that picocyanobacteria in the Baltic Sea form colonies and aggregates, influencing carbon export. This process is crucial for regulating atmospheric CO2 levels and predicting future ocean changes.
A multicentre study found patients with a rare inherited form of lupus may continue to accumulate organ damage even when disease activity appears to have declined. Long-term monitoring and more sensitive biomarkers are needed to detect ongoing subclinical inflammation and organ injury.
Researchers directly observed a heavy fermion state forming at the boundary of a one-atom-thick material and a metal, revealing new possibilities for designing quantum materials. The finding arose from hybridization between localized electrons and mobile electrons, providing direct evidence of an interfacial heavy-fermion state.
A new study published in Radiology journal found that ultrasound-guided hydrodissection provides sustained clinical and morphological improvement in patients with refractory carpal tunnel syndrome. The procedure is a steroid-free alternative that involves injecting fluid around the affected nerve to release adhesions and improve mobility.
