Translucency and contrast ratio of dimetharcyrlate resin based dental materials after bleaching: an in-vitro study.

Objective: To compare the translucency and contrast ratio of 13 different resin based restorative materials and to evaluate the effect of 2 different bleaching methods on the translucency and contrast ratio of these materials.

Methods: In this study, a total of 260 samples were prepared, 20 from each of 13 different dimethacrylate-based restorative materials. Then, each material group was divided into 4 subgroups.

Protective effects of tadalafil and N-acetyl cysteine therapy on cisplatin-induced testicular toxicity.

Purpose: To investigate whether tadalafil (TAD) and N-acetyl cysteine (NAC) can prevent cisplatin (CIS)-induced testicular toxicity.

Methods: Forty Wistar-Albino rats were divided into five groups: Control group, CIS group, TAD group, NAC group and TAD + NAC group. All groups were compared regarding body and testicular weights, testicular volumes, blood testosterone levels, testicular tissue malondialdehyde (MDA) levels, histopathological features, and testicular Cosentino and Johnsen scores.

Simultaneous quantitative screening of 53 phytochemicals from L. roots: a comparative study of supercritical CO, subcritical ethanol, and ultrasound-assisted extraction for enhanced antioxidant, antibacterial activities, and molecular docking study.

In this study, L. extracts were obtained using various green extraction techniques, including supercritical CO, subcritical ethanol, and ultrasound-assisted extraction, each performed under optimized parameters. The phytochemical content of the extracts was analyzed using the LC-MS/MS technique, quantifying 53 phytochemicals.

Diagnostic Characteristics and Clinical Relevance of Incidental Hypermetabolic Breast Lesions Detected on F-FDG PET-CT: A Retrospective Evaluation.

Rationale And Objectives: The study aimed to evaluate demographic and radiological characteristics of breast incidentalomas found on 18-fluorodeoxyglucose Positron Emission Tomography-Computed Tomography (F-FDG PET-CT) performed for extramammary indications.

Materials And Methods: A total of 12633 F-FDG PET-CT scans performed between January 1, 2018 and January 1, 2024, were retrospectively reviewed. Breast incidentalomas that had undergone breast imaging, tissue diagnosis, or at least 2-year radiological follow-up were included.

A rare complication of blood donation: MINOCA.

Blood donation is a life-saving process that involves the temporary loss of a specific blood volume. Although generally safe, it may lead to adverse reactions, particularly in first-time donors. Among these, severe outcomes like myocardial infarction (MI) are extremely rare.
