Objective: To evaluate the influence of different cleaning methods, surface treatments, and aging on the repair bond strength to a CAD/CAM glass-ceramic.
Materials And Methods: Forty-eight lithium disilicate CAD/CAM ceramic blocks were fabricated, sintered, and embedded in acrylic resin. After contamination with human saliva, they were divided according to the factors "Cleaning method" (Control-water/air spray, Air-particle abrasion with AlO, Ivoclean cleaning paste), "Surface treatment" (5% Hydrofluoric acid-HF + Silane, Monobond Etch & Prime-MEP), and "Aging" (thermocycling, no thermocycling).
Immunohistochemical identification of ACE-2 (SARS-COV II entry mechanism) in the gastrointestinal tract, kidney and lung of rhesus monkeys (Macaca mulatta) and squirrel monkeys (Saimiri sciureus).

SARS-Cov-2 is a corona virus that causes COVID-19 disease, a viral infection responsible for the pandemic decreed by the World Health Organization in March 2020. Angiotensin-converting enzyme 2 (ACE-2) functions as the main receptor for SARS-Cov-2. The study aimed to detect the expression of ACE-2 in the gastrointestinal tract, kidney, and lung in the rhesus monkeys and squirrel monkeys.

Objective: To evaluate the quality of oral health care through indicators in patients undergoing hematopoietic stem cell transplantation for the management of oral mucositis.
Methods: Thirty-five patients were evaluated. Photobiomodulation was performed during the conditioning regimen, 1 day, 5 days, and 10 days after transplantation.
Article Synopsis
- - The study analyzed 64 patients with small cell lung cancer (SCLC) to assess the expression of Delta-like ligand 3 (DLL3) and other neuroendocrine markers using immunohistochemistry and digital pathology tools; DLL3 was found expressed in 72.3% of patients.
- - The majority of patients were older adults (median age over 71), and notable findings included high expression rates of ASCL1 (97%) and a potential new role for TTF-1 as a biomarker, as it was positive in half of the cases.
- - The research highlights the variability of neuroendocrine marker expression in SCLC, suggesting that DLL3 could be a therapeutic target, while the
