BACKGROUND AND AIM: Evidence-based dentistry (EBD), including orthodontics, needs the availability and use of the high-quality studies. The aim of this study was to identify the level of evidence (LOE) of Iranian articles on orthodontics published in PubMed.METHODS: All the articles on orthodontics published from 2000 to 2015 in PubMed with Iran affiliations were extracted by typing orthodontic...

The alcohol dehydrogenase (ADH) family of enzymes catalyzes the reversible oxidation of alcohol to acetaldehyde. Seven ADH genes exist in a segment of ~370 kb on 4q21. Products of the three class I ADH genes that share 95% sequence identity are believed to play the major role in the first step of ethanol metabolism. Because the common belief that selection has operated at the ADH1B*47His allele...

Feedbacks involving low-level clouds remain a primary cause of uncertainty in global climate model projections. This issue was addressed by examining changes in low-level clouds over the Northeast Pacific in observations and climate models. Decadal fluctuations were identified in multiple, independent cloud data sets, and changes in cloud cover appeared to be linked to changes in both local tem...

OBJECTIVE Fibromyalgia (FMS) is characterized by chronic pain, high psychiatric comorbidity, and the absence of observable pathology. Our objective was to examine positive and negative affective indices, both at the trait and contextual levels, in FMS compared with a chronic pain control group, osteoarthritis (OA). METHODS The sample consisted of 126 female FMS (87) and OA (39) patients from ...

Objectives: Against the background of evidence-based treatments for schizophrenia resistant to medication, the implementation of cognitive-Rehabilitation therapy (CRT) becomes more important, especially about patients who don’t response to medication. There is less evidence for group format and face to face structure of CRT and also for resistant to medication patients. This research investigat...

As the field of education embraces the task of adopting evidence-based practices, ongoing discussion will be appropriate about the standards and format for determining whether an intervention is supported by data on its effectiveness. We propose here six criteria that may be useful in this discussion and apply these criteria to assessment of Schoolwide Positive Behavior Support (SWPBS). Because...

How to assign numerical values for probabilities that do not seem artificial or arbitrary is a central question in Bayesian statistics. The case of assigning a probability to the truth of a proposition or event for which there is no evidence other than that the event is contingent, is contrasted with the assignment of probability in the case where there is definte evidence that the event can ha...

The scientific literature on work-related back disorders was reviewed to identify consistent risk factors and to determine the strength of the association between the two. Thirty-five publications were selected with quantitative information. Lifting or carrying loads, whole-body vibration, and frequent bending and twisting proved to be the physical load risk factors consistently associated with...
