On delivery of nitric oxide (NO) to protein samples (e.g., cytochrome c'), for spectroscopic experiments it is important to avoid exposure to oxygen and to remove contaminants from the NO gas. We describe a number of techniques for steady-state UV/Vis spectrophotometry and pre-steady-state stopped-flow spectrophotometry analysis of cytochrome c'.

Background: Current treatments for penile erectile structures reconstruction are limited and remain a great challenge in clinical practice. Tissue engineering techniques using different seed cells and scaffolds to construct a neo-tissue open promising avenues for penile erectile structures repair and replacement and show great promise in the restoration of: structure, mechanical property, and function which matches the original tissue.
Methods: A comprehensive literature review was conducted by accessing the NCBI PubMed, Cochrane, and Google Scholar databases from January 1, 1990, to January, 1, 2022 using the search terms "Tissue engineering, Corpus cavernosum (CC), Tunica albuginea (TA), Acellular Matrix, Penile Reconstruction".

Bacteria biofilm infection seriously challenges clinical drug therapy. Nitric oxide (NO) was reported to disperse biofilm, eliminate bacteria resistance and kill bacteria. In this study, on the basis of membrane targeting of α-mangostin (α-MG) and the dispersion effect of NO on bacteria biofilms, we designed and synthesized 30 NO donors that α-MG was conjugated with a nitrobenzene or a nitrate and other four representative reference derivatives.

Ischemic preconditioning (IPC) therapy application to attenuate myocardial ischemia-reperfusion (MI/R) injury in clinical practice remains challenging. The secretome, derived from hypoxia-preconditioned cardiomyocytes (SHPC), potentially mimics the IPC microenvironment and facilitates IPC clinical translation. This study aims to determine whether SHPC can be a feasible alternative to IPC for attenuating MI/R injury, and to identify the functional factor of SHPC.

High glucose level, bacterial infection, and persistent inflammation within the microenvironment are key factors contributing to the delay of diabetic ulcers healing, while traditional therapeutic methods generally fail to address these issues simultaneously. Here, we present a spatiotemporally responsive cascade bilayer microneedle (MN) patch for accelerating diabetic wound healing local glucose depletion and sustained nitric oxide (NO) release for long-term antibacterial and anti-inflammatory effects. The MN patch (G/AZ-MNs) possesses a degradable tip layer loading glucose oxidase (GOx), as well as a dissolvable base layer encapsulating l-arginine (Arg)-loaded nanoparticles (NPs).
