Background Tissue with Native Target Expression Can Determine Presence of Nodal Metastasis in Head and Neck Squamous Cell Carcinoma Patients Infused with Targeted Fluorescent Tracers.

Purpose: Survival and treatment intensity in patients with head and neck squamous cell carcinoma (HNSCC) is determined by the presence of lymph node (LN) metastasis, and as a result surgical removal of potentially affected LN remains a mainstay practice. Fluorescence guided surgery (FGS) using targeted optical agents is an expanding field that shows great potential for aiding diagnosis of metastatic LN. Given variations in fluorescence background, a reference standard for regions of interest is necessary for cross patient comparison.

SIRT2 Regulates Apoptosis Signaling in Hyperoxic Acute Lung Injury.

Purpose: Oxygen therapy is helpful for patients with breathing difficulties; however, sustained supplementation with high-concentration oxygen can cause hyperoxic acute lung injury. Sirtuin 2 (SIRT2), a nicotinamide adenine dinucleotide (NAD)-dependent deacetylase, has been shown to be involved in pulmonary fibrosis, apoptosis, and inflammation. Here, we elucidated the role of SIRT2 in hyperoxic acute lung injury.
