Next-generation vascular stents can make cardiovascular therapies minimally invasive and vascular treatments safe and less burdensome. In a new advancement, researchers from Japan and China have successfully proposed a novel adaptive 4D-printed vascular stent based on shape-memory polymer composite. The stent exhibits mechanical flexibility, radial strength, biomechanical compliance, and cytocompatibility in in vitro and in vivo experiments, making them promising for future clinical applications.
Study shows AI can enable earlier identification of blood transfusion need in trauma patients, with models trained and validated using data from over 400,000 patients across North America and Europe.
Like regular strength training, blood flow restriction training strengthens muscle power and heart health, but it also improves fat distribution and energy production—an important benefit for people with type 2 diabetes.
The increasing adoption and recognition of LLMs within the academic community.
As a significant breakthrough in the field of AI, LLMs have introduced transformative advancements and innovations to academic research.
The academic community has increasingly acknowledged the potential challenges of LLMs to academic integrity, and the challenges posed by LLMs to academia are becoming increasingly diversified.
To systematically address the challenges posed by the application of LLMs in the academic domain, a comprehensive governance framework should be established from many dimensions.
COVID-19 vaccination is not the cause behind a decrease in childbirth, according to a study from Linköping University, Sweden. The results speak against rumours about vaccination and reduced fertility. The findings have been published in the journal Communications Medicine.
An international study investigating the genomic diversity of the Sudanese population reveals that the Copts originating in Egypt –who settled in the country between the seventh and eleventh centuries– have acquired a genetic variant that protects them from contracting malaria. “The acquisition of this variant has taken place very quickly, in just 1,500 years, after a group of Copts mixed with Sudanese populations with sub-Saharan characteristics”, explains David Comas, principal investigator at the Institute of Evolutionary Biology (IBE: CSIC-Pompeu Fabra University) and a full professor and researcher at the UPF Department of Medicine and Life Sciences, who has led the research. The study of 125 high-coverage genomes representing five of the country’s ethnolinguistic groups has enabled describing more than a million novel genetic variants, 1,500 of which could have implications for diseases.
