Rosacea is a chronic, inflammatory dermatological condition primarily affecting the central face, including cheeks, nose, chin, and forehead[1]. It presents with erythema, phymatous changes, papules, pustules, telangiectasia. The pathogenesis of rosacea still unknown. Patients often suffer from multiple symptoms rosacea, requiring more precise assessments individualized therapies[2]. 5-Aminolevulinic acid photodynamic therapy (ALA-PDT) has shown promise as safe effective treatment for...
Abstract To address the limitations of low relaxivity and physiological toxicity in commercial gadolinium-based contrast agents for magnetic resonance imaging (MRI), a novel manganese chelate macromolecular system was developed using flash nano-preparation technique. Herein, approach applying an instantaneous fluid device incorporated gallic acid, dopamine Mn2+ to perform in-situ polymerization covalent binding with albumin nanoconfined environment. This controllable self-assembly process...
Pulmonary hypertension (PH) is a fatal pulmonary vascular disease. The standard diagnosis of PH heavily relies on an invasive technique, i.e., right heart catheterization, which leads to delay in and serious consequences. Noninvasive approaches are crucial for detecting as early possible; however, it remains challenge, especially mild patients. To address this issue, we present new fully automated framework, hereinafter referred PHNet, noninvasively patients, improving the detection accuracy...
