The aim of this study was to evaluate the antioxidant properties of the products derived from the biodegradation of lignin by the ligninolytic enzymes present in an aqueous extract of the mushroom . A mixture obtained after the incubation of lignin for 18 h with extract was tested in vitro for its total polyphenol content, reducing power, and 1,1-diphenyl-2-picrylhydrazyl (DPPH) and hydroxyl (OH) radical-scavenging activities. The results showed that the enzymatic treatment of lignin enhanced its antioxidant performance.

- - Ex vivo fluorescence laser scanning microscopy (FCM) enables real-time imaging of fresh tissue samples without traditional slide preparation, and this study specifically investigates its application in evaluating biopsy samples from endoscopic procedures for lung lesions and lymph nodes.
- - The study involved 32 patients, showing that the FCM Vivascope 2500 could accurately assess sample adequacy and malignancy, with a perfect agreement noted between its evaluations and final histological results.
- - The findings suggest that FCM could significantly improve the speed of diagnostic information during endoscopic biopsies, potentially enhancing patient management by reducing the time needed to diagnose lung cancer.
Borderline ovarian tumor is a type of tumor with generally low malignant potential. However, these tumors pose diagnostic challenges with benign and malignant epithelial ovarian tumors because the clinical symptoms are similar and investigation procedures for specific diagnosis are still debated. In addition, a small number of borderlines transform into high-grade serous ovarian carcinoma with a poor prognosis.

- Fine-needle-aspiration-cytology (FNAC) is a safe and cost-effective method for assessing thyroid nodules, but indeterminate cytology (ITN) sometimes requires further diagnostic surgery.
- Recent studies from Europe and the U.S. suggest that thyroid cancer (TC) behaves differently based on pre-surgical FNAC results, with ITN cases showing less aggressive characteristics compared to more suspicious diagnoses.
- A commentary involving thyroid experts highlights the consistent finding that TC with ITN diagnosis has lower rates of complications and mutations, indicating a need to consider less aggressive treatment options for these patients.
Article Synopsis
- * In a study of 28 patients, RS was used to analyze thyroid cytological samples from fine needle aspirations (FNA) to evaluate cell oxidative stress, a major cancer risk factor.
- * The findings categorized patients based on changes in Raman spectra related to oxidative stress and carotenoid presence, suggesting a link between oxidative stress and thyroid diseases that could inform future research on biomarkers.
