The near-infrared (NIR) fluorescence signal in the 700 to 900 nm from molecular probes used in fluorescence image-guided surgery (FIGS) is usually weak compared to the NIR component from white light-emitting diode surgical light, which is typically switched off during FIGS to enhance the molecular fluorescence contrast of the image. We propose a simple solution to this critical issue in FIGS by removing NIR light from surgical light with a low cost commercial 3M cool mirror film 330.

Purpose: The aim of the present study is to examine the demographic data and clinical features of ocular surface injuries due to thermal burns and to evaluate LSCD in the light of global consensus.

Methods: Thirty-three eyes of 20 cases with ocular surface injury due to thermal burn who attended to the clinic between 2012 and 2023 were included in the study. LSCD severity was staged according to the global consensus which was published in 2019.

Direct thrombin inhibitors (designated as EuRL-DTIs) were partially purified from ethanol extracts of Euphorbia resinifera O.Berg latex. The obtained EuRL-DTIs comprised four major compounds: two isomers of phenolic compounds (CHO) and two amide compounds (tentatively identified as CHNO and CHNO), as identified by liquid chromatography and electrospray ionisation quadrupole time-of-flight mass spectrometry (LC-ESI-QTOF-MS/MS), attenuated total reflection-Fourier transform infrared (ATR-FTIR) spectroscopy, and/or nuclear magnetic resonance (NMR) spectroscopy.

Introduction: Iatrogenic injury to the ilioinguinal nerve and its branches during anterior inguinal hernia repair is a cause of chronic inguinal pain in up to 12 % of patients undergoing this operation. The risk of nerve injury is high, given the nerves' relatively small caliber and strictly-confined space through which they pass. In the current report, we describe using a novel fluorescence imaging system developed to detect nerve autofluorescence in a 66-year-old man who presented with a left-sided Type II inguinal hernia and underwent inguinal hernioplasty.

Objective: Cubital tunnel syndrome is a common peripheral neuropathy of the upper extremity. Anterior transposition of the ulnar nerve is an established surgical treatment option for this condition. This study aimed to introduce a novel musculofascial lengthening technique that uses only a portion of the flexor-pronator muscle mass for submuscular anterior transposition of the ulnar nerve and investigate its clinical outcomes.

Mitochondria-localized dinuclear iridium(III) complexes for two-photon photodynamic therapy.

Photodynamic therapy (PDT), as a non-invasive cancer treatment, offers significant advantages including high temporal-spatial selectivity, minimal surgical intervention, and low toxicity, thereby garnering considerable research interest from across the world. In this study, we have developed a series of dinuclear cyclometalated Ir(III) complexes as potential two-photon photodynamic anticancer agents. These Ir(III) complexes demonstrate significant two-photon absorption (2PA) cross-sections ( = 66-166 GM) and specifically target mitochondria.
