Sequential Bone Repair in Rabbit Sinus Lifts Using Bio-Oss and Hyaluronic Acid-Polynucleotide Gel (Regenfast).

Background: A comprehensive investigation to associate the use of polynucleotides and hyaluronic acid with bovine bone in maxillary sinus lift procedures in rabbits has not been performed yet. The aim was to evaluate the influence of this novel association on the processes of bone regeneration in maxillary sinus augmentation.

Methods: In this prospective, randomized, within-animal model, maxillary sinus augmentation was performed bilaterally in 12 rabbits.

Reciprocating torsional fatigue and mechanical tests of thermal-treated NiTi instruments.

Introduction: This study aimed to evaluate the mechanical properties of Reciproc, Reciproc Blue, One RECI, and R-Motion, specifically focusing on their flexibility and buckling resistance; and to assess their torsional fatigue behavior under two different reciprocation angles (150°/30° or 70°/30°).

Methods: A total of 160 instruments (40 per brand) were tested. Flexion and buckling tests were conducted using a Universal testing machine (DL 200MF) was used.

Assessing tafenoquine implementation in Brazil: a qualitative evaluation of perceptions of healthcare providers and Plasmodium vivax patients (QualiTRuST Study).

Background: To eliminate malaria by 2035, Brazil must address Plasmodium vivax. Previously, first-line treatment was chloroquine plus 7-day primaquine (PQ) without glucose-6-phosphate dehydrogenase (G6PD) deficiency testing. In 2021, point-of-care quantitative G6PD testing and single-dose tafenoquine (TQ) were piloted in two municipalities.

Control of coffee canker associated with Pseudomonas coronafaciens pv. garcae using a cocktail integrating two virulent polyvalent bacteriophages encapsulated in nanoparticles: in planta studies.

Aims: In this study we report the use of two novel lytic polyvalent phages as a cocktail in in planta assays and its efficacy in the control of bacterial halo blight (BHB) caused by Pseudomonas coronafaciens pv. garcae (Pcg) in coffee plants.

Methods And Results: Phages were isolated from samples of coffee plant leaves collected at two different locations in Brazil.

Potential of a newly isolated lytic bacteriophage to control Pseudomonas coronafaciens pv. garcae in coffee plants: Molecular characterization with in vitro and ex vivo experiments.

Traditionally, control of coffee plant bacterial halo blight (BHB) caused by the phytopathogen Pseudomonas coronafaciens pv. garcae (Pcg) involves frequent spraying of coffee plantations with non-environmentally friendly and potentially bacterial resistance-promoting copper products or with kasugamycin hydrochloride. In this study we report a leap forward in the quest for a new ecofriendly approach, characterizing (both physicochemically and biologically) and testing both in vitro and ex vivo a new lytic phage for Pcg.
