Objective: Chemicals used during canal disinfection and endodontic sealers have a deleterious effect on dentin bond strength. The aim of this study was to evaluate a novel clinical sequence to improve the resin-dentin microtensile bond strength (μTBS) to endodontically treated teeth.
Materials And Methods: Twenty human molars were distributed in four experimental groups (n = 5, N = 20): C-control group without exposure to any endodontic chemical substances (2.
Transvaginal evisceration is a rare, potentially life-threatening condition involving herniation of intra-abdominal contents, typically the small bowel, through a defect in the vaginal wall. Most commonly observed in postmenopausal women with a history of pelvic surgery or trauma, it necessitates prompt surgical intervention. We report a unique case of transvaginal evisceration in a 67-year-old postmenopausal female with rectovaginal prolapse following minor trauma.

Chronic inflammatory processes are also involved in its the etiology, as the consequence or cause of proteinopathy (amyloid and tau load in the brain). This study aimed to investigate the complete blood count and systemic inflammation indices in 61 individuals with AD, compared to 59 cognitively healthy individuals as controls.

A second culturally adapted ECAS screen facilitates the accurate characterization of ALS progression, mitigates learning effects, and supports tailored care management.
Methods: The adaptation process included forward-backward translation, cultural adaptation, and cognitive debriefing on a prospective sample of 193 ALS patients and 106 controls.
Objective: To present cases of ptosis in HIV-1 patients on long-term antiretroviral therapy (ART) and review the existing literature.
Methods: Five HIV-1-positive patients with slowly progressive bilateral ptosis underwent a comprehensive diagnostic evaluation, including imaging studies, neurophysiological testing, muscle biopsy, and genetic analysis. A literature review was conducted.
