With the progress of atherosclerosis (AS), the arterial lumen stenosis and compact plaque structure, the thickening intima and the narrow gaps between endothelial cells significantly limit the penetration efficiency of nanoprobe to plaque, weakening the imaging sensitivity and therapy efficiency. Thus, in this study, a HO-NIR dual-mode nanomotor, Gd-doped mesoporous carbon nanoparticles/Pt with rapamycin (RAPA) loading and AntiCD36 modification (Gd-MCNs/Pt-RAPA-AC) was constructed. The asymmetric deposition of Pt on Gd-MCNs catalyzed HO at the inflammatory site to produce O, which could promote the self-motion of the nanomotor and ease inflammation microenvironment of AS plaque.

Hepatocellular carcinoma is one of the leading causes of cancer deaths globally and a key hindrance to extending life expectancy. Celastrol (CEL) demonstrates excellent antitumor activity, but faces challenges like low solubility and a narrow therapeutic window, limiting its clinical application. To address these limitations, drug combinations and nano-delivery systems have emerged as effective solutions.

Processed cheese faces challenges related to short shelf life and susceptibility to microbial contamination during room temperature storage. Nisin, a natural antimicrobial peptide used for food preservation, exhibits limited sustained activity and a narrow antimicrobial spectrum, making its enhancement essential. To address these issues, this study employed electrostatic self-assembly technology to develop chitosan-pectin nanoparticles loaded with nisin (CNP) to improve processed cheese stability at room temperature.

Introduction: Breathing and postural control is reported to be both neuromuscularly and mechanically interdependent. To date, the effects of voluntary abdominal and thoracic breathing (VAB and VTB) on the EMG activity of muscles involved in both respiratory and postural functions, as well as gait biomechanics related to these breathing patterns, have not been investigated in young, healthy adults. The aim of the study was to evaluate the EMG responses of neck and trunk muscles, as well as the kinematic, stability, and kinetic parameters of gait induced by VAB and VTB compared to involuntary breathing (INB).

Charge detection mass spectrometry (CD-MS) is an emerging single-particle technique where both the / and charge are measured individually to determine each ion's mass. It is particularly well-suited for analyzing high mass and heterogeneous samples. With conventional MS, the loss of charge state resolution with high mass samples has hindered the direct coupling of MS to separation techniques like size exclusion chromatography (SEC) and forced the use of lower resolution detectors.
