Abstract Supramolecular polymer networks contain non-covalent cross-links that enable access to broadly tunable mechanical properties and stimuli-responsive behaviors; the incorporation of multiple unique non-covalent cross-links within such material

This work describes protocols for preparing specific forms of human platelet lysates from pooled platelet concentrates (PCs) and the isolation of platelet-derived extracellular vesicles (p-EVs). Clinical-grade PCs can be sourced from blood establishm

Abstract The gut microbiome and its metabolites are increasingly implicated in several cardiovascular diseases, but their role in human myocardial infarction (MI) injury responses have yet to be established. To address this, we examined stool samples

Abstract Platelets are small anucleated blood cells primarily known for their vital hemostatic role. Allogeneic platelet concentrates (PCs) collected from healthy donors are an essential cellular product transfused by hospitals to control or prevent

According to current ANSI Z136.1, IEC 60825-1 and ICNIRP guidelines, two exposure limit criteria apply for the cornea and skin: the single pulse limit and the average irradiance limit. The reduction factor CP for repetitively pulsed exposures need on

The threshold for laser-induced thermal retinal injury varies with the duration of the laser exposure and the MPEs as given in the laser safety guidelines are expected to define exposure levels not anticipated to result in retinal injury across the e

A computer model that predicts thresholds for laser induced corneal injury in the infrared wavelength range was used to systematically analyze wavelength, pulse duration and beam diameter dependencies. The thresholds were compared with the respective

The exposure and emission limits of ICNIRP, IEC 60825-1 and ANSI Z136.1 to protect the cornea are based on a limited number of in-vivo studies. To broaden the database, a computer model was developed to predict injury thresholds in the wavelength ran

The ANSI Z136.1-2014 Standard for Safe Use of Lasers is the eighth revision of the guideline which was first issued in 1973 and subsequently updated in 1976, 1980, 1986, 1993, 2000, 2007 and 2014. The 1973 Maximum Permissible Exposure (MPE) guidance

Laser safety standards committees have struggled for years to formulate adequately a sound method for treating repetitive-pulse laser exposures. Safety standards for lamps and LEDs have ignored this issue because averaged irradiance appeared to treat
