In patients with an ulcer of the stomach and duodenum at the immediate postoperative period in the complex of treatment, the low intensity laser irradiation of the anastomosis (after gastric resection) and ulcer (after the organ-preserving operations) according to the developed method by means of the modified LG-75 apparatus was used. The use of a helium-neon laser contributed to development of the severe form of anastomositis and subsequent gastrostasis. In study of gastric secretion, no considerable changes in acid formation were revealed.

Dual-mode-driven nanomotors targeting inflammatory macrophages for the MRI and synergistic treatment of atherosclerosis.

With the progress of atherosclerosis (AS), the arterial lumen stenosis and compact plaque structure, the thickening intima and the narrow gaps between endothelial cells significantly limit the penetration efficiency of nanoprobe to plaque, weakening the imaging sensitivity and therapy efficiency. Thus, in this study, a HO-NIR dual-mode nanomotor, Gd-doped mesoporous carbon nanoparticles/Pt with rapamycin (RAPA) loading and AntiCD36 modification (Gd-MCNs/Pt-RAPA-AC) was constructed. The asymmetric deposition of Pt on Gd-MCNs catalyzed HO at the inflammatory site to produce O, which could promote the self-motion of the nanomotor and ease inflammation microenvironment of AS plaque.

Deep-ultraviolet (DUV) light is essential for applications including fabrication, molecular research, and biomedical imaging. Compact metalenses have the potential to drive further innovation in these fields, provided they utilize a material platform that is cost-effective, durable, and scalable. In this work, we present aluminum nitride (AlN) metalenses as an efficient solution for DUV applications.

Endowing cyanine dyes with hydrophilicity, long blood circulation, tumor targeting, and robust therapeutic efficacy in the second near-infrared (NIR-II) window is challenging for cancer treatment. Herein, we develop cancer cell membrane-coated albumin-NIR-II cyanine dye assemblies, denoted as LZ-1105@HAm, to optimize the photophysical properties of cyanine dyes in aqueous solution for NIR-II fluorescence (FL)/photoacoustic (PA)/photothermal (PT) multimodality imaging-guided tumor homologous targeting photothermal therapy. LZ-1105@HAm exhibits good hydrophilicity, extends the half-life of blood circulation from 0.

Objectives: Transoral robotic surgery (TORS) and transoral laser microsurgery (TOLM) plus neck dissection are viable alternatives to radiotherapy as a treatment modality in select cases of oropharyngeal squamous cell carcinoma. Many centers advocate for elective ligation of the feeding arteries at index neck dissection prior to TORS/TOLM to mitigate the risk of catastrophic perioperative hemorrhage. Although there are multiple cadaveric studies in the literature to identify the lingual artery at multiple points throughout its course, there are no studies on the intraoperative identification of the lingual artery for elective ligation prior to TORS/TOLM.
