Endoscopic laser treatment is reported in 313 patients with benign rectosigmoid villous adenomas. Total tumor destruction was achieved in 92% of them, without any major complications. The circumferential extension of the tumor base was the only factor affecting this result. During the average 37-month follow-up period of the patients with total tumor destruction, 14% had a tumor recurrence. The recurrence rate after initial treatment was higher a) in patients treated for a recurrence after a previous non laser treatment, b) when the initial histology was low-grade dysplasia and c) when the tumor was located in the lower or middle rectum. Because treatment is long and difficult with a high cancer rate, laser treatment for patients with a circumferential villous adenoma should be limited to nonsurgical candidates. In the other cases, laser is well adapted to old and fragile patients, when transanal resection seems difficult or in case of recurrence after a previous non-laser treatment.

Gold nanoparticles (AuNPs) play a key role in the field of nanomedicine due to their fascinating plasmonic properties as well as their great biocompatibility. An intriguing application is the use of plasmonic photothermal therapy (PPTT) mediated by anisotropic AuNPs irradiated with a near-infrared (NIR) laser for treating ocular diseases in ophthalmology. For this purpose, bipyramidal-shaped AuNPs (BipyAu), which were surface-functionalized with three different organic ligands (citrate, polystyrene sulphonate (PSS), and cetyltrimethylammonium bromide (CTAB)), were synthesized.

The aim of the present study was to evaluate the efficacy and safety of laser localization combined with soft-channel minimally invasive surgery (MIS) for the treatment of cerebral hemorrhage, and to develop stereotactic alternatives that are cost-effective, safe and precise for underdeveloped regions. To meet this aim, 60 patients with cerebral hemorrhage were randomly assigned to the control group (n=30) or the study group (n=30). The patients in the study group were treated with laser localization combined with soft-channel MIS to remove the hematoma, whereas the control group was treated with YL-1 needle puncture to drain the intracranial hemorrhage.

Thermodynamic therapy (TDT) is a promising alternative to photodynamic therapy (PDT) by absorbing heat through thermosensitive agents (TSAs) to generate oxygen-irrelevant highly toxic free radicals. Therefore, TDT can be a perfect partner for photothermal therapy (PTT) to achieve efficient synergistic treatment of anoxic tumors using a single laser, greatly simplifying the treatment process and overcoming hypoxia limitations. However, the issues of how to improve the stability and delivery efficiency of TSAs still need to be addressed urgently.

Bacterial infections, such as sepsis, require prompt and precise identification of the causative bacteria for appropriate antibiotics treatment. Traditional methods such as culturing take 2-5 days, while newer techniques such as reverse transcription-polymerase chain reaction and mass spectrometry are hindered by blood impurities. Consequently, this study developed a surface-enhanced Raman scattering (SERS)-based acoustofluidic technique for rapid bacterial detection without culturing or lysing.

Objective: This study aims to investigate the correlation between the development of diabetic retinopathy (DR) and the changes in corneal sub-basal nerve plexus (SNP) and corneal dendritic cells (DCs).
Methods: 58 patients with type 2 diabetes mellitus (T2DM) and 30 age- and sex-matched healthy participants underwent assessment of the corneal nerve. The DR group was divided into no diabetic retinopathy (NDR) and 29 eyes with mild to moderate non-proliferative diabetic retinopathy (NPDR).
