Abstract Bacterial infections account for countless deaths globally. Antibiotics are the primary countermeasure; however, alarming spread of antibiotic‐resistant strains necessitates alternative solutions. Silver and silver compounds have emerged as promising antibacterial agents. However, issues related to cytotoxicity genotoxicity remain concern. To overcome these challenges, this proposes an easy‐to‐control straightforward method synthesize novel Silver─gallium (Ag─Ga) nano‐amalgamated...

Segmentation of the left ventricular (LV) myocardium in 2-D echocardiography is essential for clinical decision making, especially geometry measurement and index computation. However, segmenting a time-consuming process challenging due to fuzzy boundary caused by low image quality. The ground-truth label employed as pixel-level class associations or shape regulation segmentation, which works limit effective feature enhancement echocardiography. We propose training strategy named...

Acute lung injury (ALI) and acute respiratory distress syndrome (ARDS) are major causes of failure, but currently, no effective pharmacotherapy exists for these disorders. Alveolar macrophages play a critical role in both the acute/initial phase chronic/resolving ALI, rendering them potential therapeutic target. Interleukin-4 (IL-4), Th2 cytokine, not only directly inhibits secretion pro-inflammatory factors from also drives to anti-inflammatory tissue remodeling M2 type. However, short...

Intravascular photoacoustic (IVPA) imaging, benefiting from high optical contrast, large imaging depth and absorption specificity, is of great potential for lipid-rich plaque detection. However, the diameters reported IVPA endoscopes are too big to intervene into coronary artery branches. Here, by designing an ultracompact house embedded with a side-fire fiber miniature single-element ultrasound transducer, we developed ultrafine endoscope diameter 0.7 mm aiming at branches atherosclerotic...

The prevailing open-structure intravascular photoacoustic (IVPA) endoscope emits a gradually deformed laser beam with exposed optical or acoustical components bearing pollution and damage in arterial lumen. Deformed scanning, which causes low excitation efficiency serious deterioration of the transverse resolution, is current big obstacle to application endoscopy imaging. Hence, stable reliable IVPA indispensable. In this letter, we designed high-robustness (HR-IVPA) hermetically sealed...
