In clinical optical molecular imaging, the need for real-time high frame rates and low excitation doses to ensure patient safety inherently increases susceptibility to detection noise. Faced with the challenge of image degradation caused by severe noise, image denoising is essential for mitigating the trade-off between acquisition cost and image quality. However, prevailing deep learning methods exhibit uncontrollable and suboptimal performance with limited interpretability, primarily due to neglecting underlying physical model and frequency information.

The absence of an effective imaging tool for diagnosing renal ischemia-reperfusion injury (RIRI) severely delays its treatment, and currently, no definitive clinical interventions are available. Pyroglutamate aminopeptidase-1 (PGP-1), a potential inflammatory cytokine, has shown considerable potential as a biomarker for tracing the inflammatory process in vivo. However, its exact role in the enhanced visualization of RIRI in complex biological systems has yet to be fully established.

Background: Liver transplant (LT) patients face various challenges, including an increased risk of coronary artery disease (CAD) for a variety of reasons, with 70% of LT recipients having one cardiovascular event. Coronary artery bypass grafting (CABG) remains one of the most commonly performed major surgical procedures in the United States, with 20-30% of LT patients requiring a CABG. Many studies have analyzed when to perform a CABG and CAD workup pre-LT, but this population remains a problem.

Department of Medicine, University of Washington, Seattle.
Importance: For patients hospitalized with acute decompensated heart failure (ADHF), the presence of kidney dysfunction can substantially shape prognosis and treatment options. Yet little is known about the lived experiences of these medically vulnerable patients.
Objective: To elicit accounts of the illness and care experiences of patients currently or recently hospitalized with ADHF and kidney dysfunction in order to identify potential opportunities to improve care.
Hemocompatible nucleosome-inspired heparin-mimicking hydrogel microspheres for safe and efficient extracorporeal removal of circulating histones in critically ill patients.

Circulating histones have been identified as essential mediators that lead to hyperinflammation, platelet aggregation, coagulation cascade activation, endothelial cell injury, multiple organ dysfunction, and death in severe patients with sepsis, multiple trauma, COVID-19, acute liver failure, and pancreatitis. Clinical evidence suggests that plasma levels of circulating histones are positively associated with disease severity and survival in patients with such critical diseases. However, safe and efficient therapeutic strategies targeting circulating histones are lacking in current clinical practice.
