Sepsis and survival in critically ill calves: Risk factors and antimicrobial use

open access: yesJournal of Veterinary Internal Medicine, Volume 37, Issue 1, Page 374-389, January/February 2023., 2023
Abstract Background Sepsis is a life‐threatening disease for which critically important antimicrobials (CIA) frequently are used. Diagnostic and therapeutic guidelines for sepsis and critically ill calves are largely lacking. Objectives Identify factors associated with mortality in critically ill calves and describe bacteria obtained from blood ...

Antibacterial Essential Oils as Adjuvants to Inhibit Antibiotic Resistance in Multi‐Resistant Bacteria.

open access: yesChemistry &Biodiversity, Accepted Article.
In order to contribute to the fight against the antibiotic resistance crisis, we used a dual‐activity prospection strategy for natural product mixtures with antibiotic resistance modulating and antibacterial activities in the essential oils (EOs) of Artemisia ludoviciana, Lippia graveolens and Cosmos bipinnatus against multidrug resistant strains of ...

Periodontal microbiology and microbial etiology of periodontal diseases: Historical concepts and contemporary perspectives

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract This narrative review summarizes the collective knowledge on periodontal microbiology, through a historical timeline that highlights the European contribution in the global field. The etiological concepts on periodontal disease culminate to the ecological plaque hypothesis and its dysbiosis‐centered interpretation.

Frosted DNA: β‐Galactosidase Control of Oligonucleotide Activity

open access: yesChemistry – A European Journal, EarlyView.
β‐Galactosidase is expressed at low level in many native cells and strongly upregulated in senescent cells. In the present study, we use β‐galactosidase activity as internal trigger to control the hybridization of oligonucleotides–eventually selective in senescent cells. ABSTRACT We introduce a novel approach for the control of oligonucleotides through

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...
