Sex‐specific impact of repeated adolescent vapour exposure to JWH‐018 on dopamine response, behaviour and pharmacokinetics across adolescence and adulthood

open access: yesBritish Journal of Pharmacology, EarlyView.
Abstract Background and Purpose Alarming trends show that vaping e‐cigarettes containing synthetic cannabinoid receptor agonists, such as JWH‐018, is increasing among youth. However, the effects of these trends are unclear in both sexes. We therefore characterized the neuropharmacological effects of adolescent JWH‐018 inhalation in male and female rats.

Safer Access With Fewer Transfusions: Revisiting Platelet Thresholds in Pediatric Central Venous Catheterization

open access: yesEuropean Journal of Haematology, EarlyView.
ABSTRACT Background Central venous catheters (CVCs) are essential in pediatric hematology‐oncology, for the administration of chemotherapy and supportive therapy. Thrombocytopenia increases the risk of bleeding and current guidelines recommend prophylactic platelet transfusions below 40–50 × 109/L, though evidence is limited and transfusions entail ...

Biomodification of dentin collagen with hydroalcoholic propolis extract: Impact on resin–dentin adhesion

open access: yesEuropean Journal of Oral Sciences, EarlyView.
Abstract This in vitro study evaluated the effect of hydroalcoholic propolis extract (HPE) as a collagen cross‐linking agent for preserving the dentin–adhesive interface. Dentin beams from human third molars were demineralized with 10% phosphoric acid and assigned to five treatments: distilled water (control), 6.5% grape seed extract (GSE), and HPE at ...

Locating nests of endangered bumble bees: Lessons from field trials in northern Germany

open access: yesInsect Conservation and Diversity, EarlyView.
Tracking bumble bees to find their nests using coloured strips of paper stuck to their thorax proved to be the most suitable method, while radio transponders were too heavy. Tracking times of up to 2 h and distances of up to 800 m were achieved with strips of pink craft tissue paper.

Extrusion Techniques—Clinical Applications of Modern Tooth Preservation Concepts and Their Comparison

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objectives To present and compare several extrusion techniques in case of insufficient tooth structure to create a sufficient ferrule and consider the biological width. Clinical Considerations Extrusion methods based on orthodontic or surgical techniques are commonly applied, well‐described, and predictable extrusion methods. Elastics with the

Universal Dental Adhesives Containing Zinc Oxide and Copper Nanoparticles Improve Interface on Caries‐Affected Dentin After 2 Years: In Vitro Study

open access: yesJournal of Esthetic and Restorative Dentistry, EarlyView.
ABSTRACT Objective To evaluate the effect of adding zinc oxide and copper nanoparticles (ZnO/CuNp) into universal adhesives (UAs) on resin–dentin microtensile bond strength (μTBS), nanoleakage (NL), and presence of ZnO/Cu within the hybrid layer on caries‐affected dentin, both at baseline (T0) and after 2 years of water storage (T2).
