Genomic context as well as sequence of both and penicillin-binding protein 5 contributes to β-lactam resistance in .

Unlabelled: Penicillin-binding protein 5 (PBP5) of () is vital for ampicillin resistance (AMP-R). We previously designated three forms of PBP5, namely, PBP5-S in clade B strains [ampicillin susceptible (AMP-S)], PBP5-S/R (AMP-S or R), and PBP5-R (AMP-R) in clade A strains. Here, deletion resulted in a marked reduction in AMP minimum inhibitory concentrations (MICs) to 0.

Ibero-Panamerican Federation of Periodontology Delphi study on the trends of periodontology and periodontics by the year 2030. A Latin American consensus.

Background And Objective: As elsewhere in the world, the prevalence of periodontitis in stages I-II is high in the Latin American population, this scenario emphasizes the need for identification of urgent needs for allocating adequate resources to provide diagnosis, prevention, and treatment of these diseases. The aim of this Delphi study was to predict the trends in periodontology/periodontics in the Latin American region by the year 2030.

Methods: A steering committee and an advisory group of experts in periodontology/periodontics were selected from 16 countries.

Chachafruto starch: Physicochemical characterization, film-forming properties, and 3D printability.

This work aimed to characterize the physicochemical, film-forming properties, and 3D printability of a nonconventional starch from chachafruto. The chachafruto native starch (CHS) presented an excellent extraction yield (10 % db) and purity (99 % db), along with an oval and round morphology, a smooth surface with few defects, and a mean diameter of 15.4 μm.

Effect of Essential Oils from Lemongrass and Tahiti Lime Residues on the Physicochemical Properties of Chitosan-Based Biodegradable Films.

This work aimed to evaluate the impact of adding two essential oils (EO) from lemongrass (LEO) and Tahiti lime (TLEO) on the physical, mechanical, and thermal properties of chitosan-based biodegradable films. Six film formulations were prepared: two controls with chitosan concentrations of 1% and 1.5% /, two formulations combining the two chitosan concentrations with 1% LEO /, and two formulations combining the two chitosan concentrations with 1% TLEO /.
