Chatbot-based multimodal AI holds promise for collecting medical histories and diagnosing ophthalmic diseases using textual and imaging data. This study developed and evaluated the ChatGPT-powered Intelligent Ophthalmic Multimodal Interactive Diagnostic System (IOMIDS) to enable patient self-diagnosis and self-triage. IOMIDS included a text model and three multimodal models (text + slit-lamp, text + smartphone, text + slit-lamp + smartphone).

The presence of carbapenem-resistant (CR) has become one of the leading causes of life-threatening, hospital-acquired infections globally, especially with a notable prevalence in intensive care units (ICUs). The cross-transmission of microorganisms between patients and the hospital setting is crucial in the development of CR colonization and subsequent infections. Recent studies indicate that colonization typically precedes infection, suggesting the effectiveness and necessity of preventing CR colonization as a primary method to lower infection risks.

Bismuth-layered ferroelectric nanomaterials exhibit great potential for piezo-photocatalysis. However, a major challenge lies in the difficulty of recovering the catalytic powders, raising concerns regarding secondary pollution of water. In this work, a novel hierarchical porous ferroelectric ceramic containing {110} surface-exposed BiNdTiO (BIT-Nd) nanosheet arrays is grown on a porous ceramic matrix for efficient and recyclable piezo-photocatalysis.

Objective: The prognosis for severe asthma is poor, and the current treatment options are limited. The methyl-CpG binding domain protein 2 (MBD2) participates in neutrophil-mediated severe asthma through epigenetic regulation. Neutrophil extracellular traps (NETs) play a critical role in the pathogenesis of severe asthma.

Overexpression of uridine-cytidine kinase 2 (UCK2), a key enzyme in the pyrimidine salvage pathway, is implicated in human cancer development, while its regulation under nutrient stress remains to be investigated. Here, we show that under glucose limitation, AMPK phosphorylates glycinamide ribonucleotide formyltransferase (GART) at Ser440, and this modification facilitates its interaction with UCK2. Through its binding to UCK2, GART generates tetrahydrofolate (THF) and thus inhibits the activity of integrin-linked kinase associated phosphatase (ILKAP) for removing AKT1-mediated UCK2-Ser254 phosphorylation under glucose limitation, in which dephosphorylation of UCK2-Ser254 tends to cause Trim21-mediated UCK2 polyubiquitination and degradation.
