Exercise activates autophagy and lysosome system in skeletal muscle, which are known to play an important role in metabolic adaptation. However, the mechanism of exercise-activated autophagy and lysosome system in obese insulin resistance remains covert. In this study, we investigated the role of exercise-induced activation of autophagy and lysosome system in improving glucose metabolism of skeletal muscle.

High expression of drug efflux pump makes antibiotics ineffective against bacteria, leading to drug-resistant strains and even the emergence of "superbugs". Herein, we design and synthesize a dual functional o-nitrobenzene (NB)-modified conjugated oligo-polyfluorene vinylene (OPFV) photosensitizer, OPFV-NB, which can depress efflux pump activity and also possesses photodynamic therapy (PDT) for synergistically overcoming drug-resistant bacteria. Upon light irradiation, the OPFV-NB can produce aldehyde active groups to covalently bind outer membrane proteins, such as tolerant colicin (TolC), blocking drug efflux of bacteria.

Competency-based medical education has become a means in physician assistant (PA) education to ensure learner readiness for practice; align educational expectations; and assess knowledge, skills, and attitudes. Competency-based education may also serve to meet accreditation requirements. Creating program-defined competencies and associated milestones can help a PA program align with their mission and vision, developmentally guide learners through the curriculum, and ensure program assessments measure the tasks required of practice-ready graduates.

The current study aimed to propose a method to directly measure right cervical vagal nerve activity (cVNA) alongside renal sympathetic nerve activity (RSNA) in conscious rats. The right cervical vagus nerve was surgically exposed and fitted with a bipolar electrode to record cVNA. A microcatheter was used to administer levobupivacaine to selectively block afferent cVNA.

Biobased poly(ethylene furanoate) (PEF)/poly(ε-caprolactone) (PCL) block copolymers have been synthesized using ring opening polymerization (ROP) of ε-caprolactone (ε-CL) in the presence of PEF in different mass ratios. An increase in intrinsic viscosity is observed for the block copolymers with higher ε-CL content due to the extension of their macromolecular chain. Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MS) was employed to understand the composition and structure of the produced block copolymers.
