Evaluation of the marginal fit of lithium disilicate single crowns fabricated with the conventional (IPS e.max Press) and CAD/CAM (IPS e.max CAD) methods: a systematic review and meta-analysis.

Aim: The purpose of the present systematic review and meta-analysis was to evaluate the marginal adaptation of single-unit full-coverage lithium disilicate fixed dental restorations fabricated with the conventional heat-pressed technique and the digital CAD/CAM workflow.

Materials And Methods: The present study was conducted according to the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. Α study research was conducted in Medline via PubMed and Cochrane Library databases together with a hand search of studies published until June 2022.

Characteristics of intraoral scan bodies and their influence on impression accuracy: A systematic review.

Objective: The aim of this systematic review was to evaluate the influence of the characteristics of intraoral scan bodies (ISBs) on the accuracy of intraoral scanning.

Materials And Methods: An electronic search was conducted through PubMed (MEDLINE), Scopus and Cochrane Library, up to March 2023. The literature search intended to retrieve all relevant clinical and in vitro studies about the effect that the various properties of ISBs may have on the accuracy (trueness and precision) of intraoral scanning.

Platelets transfusion in Greece: Where, when, why? A national survey.

Background: Platelet transfusion is among the most useful therapeutic tools in modern clinical settings which mean that ensuring an adequate supply is of paramount importance.

Aim: The aim of our study was to record the use and wastage of platelet concentrates (PCs) in Greece, so as to come up with evidence-based interventions.

Methods: The study was conducted during May and June 2015.

Current Practice in FFP Preparation and Use in Greece: A National Survey.

Objective: Fresh frozen plasma (FFP) transfusion is widely used in modern clinical settings. Practices regarding its use vary due to lack of guidelines from randomized trials. The aim of this study was to assess both the current practices regarding FFP production, use, and wastage and the implementation of quality control (QC), female donor plasma production policies, and use of pharmaceutical hemostatic agents in Greece.

A modified flow cytometry method for objective estimation of human CD4 regulatory T cells (CD4 Tregs) in peripheral blood, via CD4/CD25/CD45RO/FoxP3 labeling.

Background: Several methods exist for flow-cytometric estimation of human peripheral blood CD4 T regulatory cells (CD4 Tregs).

Methods: We report our experience with the estimation of human CD4 Tregs via three different characterizations using flow cytometry (CD25 FoxP3 , CD25 CD127 FoxP3 , and CD4 CD25 CD45ROFoxP3 ) in normal subjects. We have used these methods on the control populations from two studies (32 and 36 subjects, respectively), the latter two methods retrospectively on the subjects of the first study.
