Evaluation and comparison of four types of bio-ceramic materials AGM MTA, Ortho MTA, pro root MTA and Cem cement in oral and dental health.

Background And Objectives: Mineral Trioxide Aggregate (MTA) is one of the main retrograde filling materials that is used today as a root end filling material and perforation repair material. This study was conducted with the aim of investigating the antibacterial and antifungal properties of four types of bio-ceramic materials, AGM MTA, Ortho MTA, Pro root MTA and Cem cement for oral and dental health.

Methods: In this study, the antibacterial activity of four types of bio-ceramic materials against two bacterial strains of Enterococcus faecalis (ATTC 29212), Escherichia coli (ATTC 35318) and antifungal activity against Candida albicans (ATTC 10231) were investigated using the well diffusion method.

Antibiofilm and cytotoxic potential of extracellular biosynthesized gold nanoparticles using actinobacteria sp. KMN.

This study intends to biosynthesize gold nanoparticles (AuNPs) using sp. KMN and to investigate its potential antibiofilm, cytotoxic and antioxidant activities. The physicochemical characterization of biosynthesize AuNPs was identified by UV-Visible, energy-dispersive X-ray, and Fourier transform infrared spectroscopy, as well as high-resolution transmission electron microscopy, X-ray diffraction, zeta potential, and dynamic light scattering methods.

The Association between Lifestyle, Occupational, and Reproductive Factors and Colorectal Cancer Risk.

Objective: Association of lifestyle, reproductive and environmental factors has been investigated with increased risk of colorectal cancer in different studies. We explored evidence and investigated association between various risk factors and colorectal cancer. Methods: This case- control study was conducted 155 colorectal cancer patients and 150 hospital-controls.

Predictive Validity and Inter-Rater Reliability of the Persian Version of Full Outline of Unresponsiveness Among Unconscious Patients with Traumatic Brain Injury in an Intensive Care Unit.

Introduction: The Glasgow Coma Scale (GCS) has some limitations when evaluating the unconscious patient. This study aims to validate the Persian version of the FOUR (Full Outline of Unresponsiveness) score as a proposed substitute.

Methods: Two nurses, two nursing students, and two physicians scored the prepared Persian version of the FOUR and GCS in 84 patients with acute brain injury.
