Surgical endodontic treatment of maxillary incisors: Case report.

This study aims to highlight the possibility of an effective endodontic surgical surgery when nonsurgical treatment of the right maxillary anterior teeth has failed. One year after the apicoectomy, the periapical lesion has completely healed, new bone has formed, and the patient is symptom-free.

Patterns of Immunohistochemical Expression of P53, BCL2, PTEN, and HER2/neu Tumor Markers in Specific Breast Cancer Lesions.

Objective: This study aimed to associate the expression of P53, BCL2, PTEN, and HER2/neu tumor markers in specific breast cancer lesions.

Methods: This study analyzed the immunohistochemical expression of P53, BCL2, PTEN, and HER2/neu tumor markers for 306 patients who presented with lesions. Tissue blocks and patients' identification data were retrieved from the department of pathology, AL Madinah Almonwarah hospital, Al Madinah, UAE.

Investigation of the structural, electrical, and dielectric properties of LaSmSrMn Cr O for electrical application.

In the present research, polycrystalline samples of LaSmSrMn Cr O are prepared using the self-combustion method. Then, we have studied their crystalline structure, and dielectric and electrical properties. The X-ray diffraction study shows that all the samples exhibit a single phase with orthorhombic structure (space group ).

Study of the structural, electronic, magnetic and magnetocaloric properties of LaCaMnVO sample: first-principles calculation (DFT-MFT).

This paper presents a correlation between experimental and theoretical approaches to study the structural, electronic, magnetic, and magnetocaloric properties of LaCaMnVO. The studied compound crystallizes in the orthorhombic space group. The calculated DOS using the DFT + U method proves that LaCaMnVO sample exhibits semi-metallic behavior, which is preferred in spintronic applications.

Is sputum cytology reliable for detection of atypical lung epithelial proliferative changes triggered by cigarette smoking?

Background: In recent years, Saudi Arabia has witnessed major tobacco smoking-related disease, such as cardiovascular disease and cancer, particularly among the younger population.

Methodology: The present study aimed at evaluating the effect of cigarette smoke on lung epithelial cells.

Results: This was a cross-sectional case-control study involving 300 apparently healthy volunteers living in Ha'il, Northern Saudi Arabia.
