Acquiring weak annotations for tumor localization in temporal and volumetric data

Researchers propose a novel annotation strategy called Drag&Drop, which enables manual labeling based on a single 2D annotation in high-dimensional volumetric data. The proposed framework achieves a comparable tumor detection rate to per-pixel annotations and higher rates than alternative weak annotation strategies.

An auxiliary CHD diagnostic system based on multi-view and multi-modal transthoracic echocardiograms

A new auxiliary CHD diagnostic system has been developed to identify TTE cardiac views, integrate information from various views and modalities, and predict the probability of a subject being normal or having a heart defect. The system uses a hierarchical network structure and has been shown to accurately detect children with CHD.

Variations in “ancient” immune cells linked to patients’ survival in cancer

Researchers discovered that variations in macrophages, ancient immune cells, are linked to patients' recovery and survival in diffuse large B-cell lymphoma. The study found subsets of macrophages associated with relapse after chemotherapy, predicting disease progression and potential new therapeutic approaches.

World-first regulations to combat sedentary behaviour among children in China show global promise

New regulations in China significantly reduced daily sedentary time by 13.8% and increased students' likelihood of meeting screen time recommendations. The measures, which restricted online gaming and homework assignments, were found to be effective in improving children's physical and mental wellbeing.

FAST discovers the most distant neutral hydrogen galaxies

Scientists have discovered six high-redshift galaxies using the FAST telescope, finding significantly more atomic hydrogen gas than previously surveyed galaxies. This reveals that galaxies four billion years ago had more star-forming gas than current-day galaxies, challenging previous assumptions.

Cardiovascular burden of the V142I transthyretin variant

The V142I transthyretin variant is associated with substantial risk for heart failure hospitalization and death in Black individuals, particularly those with reduced ejection fraction. Further investigation into the complex interplay between the variant, ancestry, social determinants of health, and biological factors is warranted.

Randomized trial reveals anti-inflammatory power of aerobic exercise in adults with obesity—helping to mitigate risks of metabolic diseases

A randomized trial found that aerobic exercise significantly reduced inflammatory markers in adults with obesity, including IL-6 and IFN-γ levels. Exercise combined with liraglutide treatment showed no additional benefits in reducing inflammation compared to placebo or liraglutide alone.

Individuals living with overweight or obesity are more likely to be absent from work due to ill health than those with normal weight, Europe-wide study finds

A Europe-wide study found that individuals living with overweight or obesity have a higher probability of being absent from work due to health issues, as well as taking longer sick days. This has significant implications for economies and productivity across the continent.

Hide and seek between atoms. Find the dopant!

The team developed a deep learning AI technique to quantitatively analyze cation mixing using atomic structure images. This approach revealed that introducing metal dopants like aluminum, titanium, and zirconium into the transition metal layer fortified bonds between nickel and oxygen atoms, curbing cation mixing.
