Antibacterial effect of 940 nm diode laser on -infected root canals.

Background: This study compared the antibacterial effects of 940 nm diode laser and sodium hypochlorite and chlorhexidine irrigations on in human permanent single-rooted teeth.

Materials And Methods: In this study, 65 extracted human single-rooted teeth were prepared using the crown-down method using rotary files. The root canals were irrigated with 5.

Investigating preschool-aged chronotype and social jetlag as predictors of early adolescent diet and BMI z-score: an eight-year follow-up from the DAGIS study.

Background/objectives: Circadian health plays an important role in overall well-being. The objective of this study was to examine whether potential indicators of circadian disruption, such as exhibiting a later chronotype or greater social jetlag, in preschool-age could predict dietary habits or BMI z-scores in an eight-year follow-up.

Subjects/methods: Our data included 210 children who participated in the DAGIS Survey in 2015-2016 (baseline, mean [SD] age: 4.

Mixed- and multi-relative biological effectiveness model simultaneous optimization in carbon ion radiotherapy: A proof-of-concept.

Background And Purpose: In carbon ion radiotherapy (CIRT), different relative biological effectiveness (RBE) models have been used for calculating RBE-weighted dose (D). Conversion between current RBE predictions and introduction of novel approaches remains a challenging task. Our aim is to introduce a framework considering multiple RBE models simultaneously during CIRT plan optimization, easing the translation between D prescriptions.

COVID-19 Impact on Pathology Education Program in Iran.

Background & Objective: The coronavirus disease brought worldwide uncertainty, and Iran was affected by it as well as many other countries in the world. Halting face-to-face education due to social distancing and resident re-employment in clinical wards leads to defective education. The aim of this survey was to evaluate the advantages and disadvantages of modifications made in pathology residency education in Iran.

Cerebrospinal Fluid Analysis in Patients with Post-neurosurgical Procedures: Meningitis vs. Non-meningitis.

Background & Objective: Cerebrospinal fluid (CSF) analysis is helpful in the diagnosis of infections of the central nervous system (CNS), especially after neurosurgical procedures. This study aimed to evaluate the diagnostic value of CSF markers for diagnosis of post-neurosurgical meningitis (PNM).

Methods: Patients with neurosurgical procedures whose CSF was obtained for any reason (meningitis and non-meningitis) during 2020 and 2022, at Imam Khomeini Hospital Complex, Tehran, Iran, were included.
