A study found that viral interactions inside cells influence antiviral resistance outcomes, while a less potent drug may ironically improve its future utility by promoting social interactions in viruses. The researchers suggest a trade-off between hitting the virus hard and allowing resistance to rise.
Headache disorders affect nearly one in every three people, causing significant disability and health loss. Migraine and medication overuse drive most of the global burden, emphasizing the need for improved prevention, management, and access to care.
Ibezapolstat, a new antibiotic, has been shown to be effective in treating Clostridioides difficile (C. diff) infections with high rates of sustained clinical cures.

The study highlights the importance of acknowledging the contributions of marginalized groups in medical research.
The Center for Research Innovation in Biotechnology (CRIB) has developed a comprehensive database of active pharmaceutical ingredients with evidence of clinical testing. The database provides valuable information on drug discovery and development, including pricing, sponsors, and intended clinical applications.
The study analyzed 63 tumor samples from 10 common malignancies, revealing how malignant cells specialize in growing tumors and non-cancer cells contribute to the immune system's suppression. The findings suggest a hierarchical structure of tumors with specific hallmark expression patterns.
Researchers analyzed 101 Chinese AML samples and identified three subtypes with different molecular characteristics and clinical outcomes. The study also found potential drug combinations that could improve treatment efficacy for subtype S-II&III patients who benefited from allogenic haematopoietic stem cell transplantation.
Researchers from Osaka University used machine learning to assess the shapes, sizes, and other physical features of bacteria based on microscope images. The results showed that antibiotic-resistant strains were fatter or shorter than their parental strains, especially those resistant to quinolone and β-lactams.
Researchers developed a novel EIT-EVA PCB sensor for non-invasive assessment of drug inhibition on ion channels. The system enables real-time monitoring of ion flow changes in response to drug exposure, offering a faster and more efficient alternative to traditional methods.
A study by Dr. Takanori Sekito and colleagues reveals a strong association between vaginal pathogenic Escherichia coli and recurrent cystitis in postmenopausal women, suggesting that targeting both the urinary bladder and vagina is crucial for effective treatment.
