Anaerobic Adhesive Effect on the Counter-Torque of Zirconia Implant Abutment Screws: In Vitro Study.

Introduction: Implantology has become a primary solution for tooth loss due to excellent osseointegration and high long-term success rates. However, complications such as abutment screw loosening, especially in implant-supported single crowns, compromise prosthesis longevity. Anaerobic adhesives (AAs) have shown promise in mechanical fields for preventing screw loosening, but their effectiveness in dental implants, particularly zirconia, remains uncertain.

The Mental Health Literacy and Stigma Scale-Bilingual Cultural Adaptation: Validity and Reliability Pilot Study in Nursing Students.

Aim: To describe and evaluate the psychometric properties (reliability and construct validity) of the Mental Health Literacy and Stigma Scale-Bilingual (MHLaSS-B).

Design: This is a methodological study designed in a convenience sample of 271 Portuguese and Spanish nursing students who volunteered to participate in the research.

Methods: The Mental Health Literacy and Stigma Scale-Bilingual version (Spanish and Portuguese) was used for data collection.

Relationships that promote and threaten family hope during pregnancy and care for high-risk newborns.

Objective: To understand the relationships that promote and threaten family hope during pregnancy and in the care of high-risk newborns.

Method: Qualitative research, guided by the theoretical framework of Understanding the Complex Nature of Hope, carried out between December 2021 and March 2022, with 28 members of 14 families attended at a multidisciplinary outpatient clinic for at-risk newborns in Minas Gerais, Brazil. Data obtained from interviews in thematic oral history allowed the construction of narratives, genograms and ecomaps, which were subjected to deductive thematic analysis procedures.

Uncertainties around net-zero climate targets have major impact on greenhouse gas emissions projections.

Globally, more than 100 countries have adopted net-zero targets. Most studies agree on how this increases the chance of keeping end-of-century global warming below 2°C. However, they typically make assumptions about net-zero targets that do not capture uncertainties related to gas coverage, sector coverage, sinks, and removals.

First comprehensive report on the chemical composition of the floral perfume of (Orchidaceae).

This study presents the first complete analysis of the chemical composition of the flowers of the species and . The compounds were extracted distillation and simultaneous extraction and analysed using gas chromatography coupled to mass spectrometry. A total of 82 compounds were identified and the results reveal significant differences in the abundance of compounds between the species.
