Ligand interaction landscape of transcription factors and essential enzymes in E. coli.

Knowledge of protein-metabolite interactions can enhance mechanistic understanding and chemical probing of biochemical processes, but the discovery of endogenous ligands remains challenging. Here, we combined rapid affinity purification with precision mass spectrometry and high-resolution molecular docking to precisely map the physical associations of 296 chemically diverse small-molecule metabolite ligands with 69 distinct essential enzymes and 45 transcription factors in the gram-negative bacterium Escherichia coli. We then conducted systematic metabolic pathway integration, pan-microbial evolutionary projections, and independent in-depth biophysical characterization experiments to define the functional significance of ligand interfaces.

[Modified questionnaire as a method for population-based caries risk screening without exploratory methods: a cross-sectional observational pilot study].

Objective: Caries Management by Risk Assessment (CAMBRA) is a questionnaire used to diagnose the patient's overall caries risk. This study aimed to present a self-assessment questionnaire based on CAMBRA which, unlike the original, is completed by parents/caregivers, without the need for a dental examination, allowing a presumptive diagnosis to be established in children under seven years of age excluded from the oral health programme of the National Health System to establish individualised recommendations for caries risk and their early inclusion in preventive programmes of the Madrid Health Service (Madrid, Spain).

Methods: A cross-sectional observational study was carried out following STROBE guidelines using for the first time a self-assessment questionnaire based on CAMBRA in a population of children aged from three to six years from a nursery school in Madrid (Spain).

Understanding Solid-Based Platelet-Rich Fibrin Matrices in Oral and Maxillofacial Surgery: An Integrative Review of the Critical Protocol Factors and Their Influence on the Final Product.

Post-COVID Interstitial Lung Disease-The Tip of the Iceberg.

The proportion of symptomatic patients with post-coronavirus 2019 (COVID-19) condition (long COVID) represents a significant burden on the individual as well as on the health care systems. A greater understanding of the natural evolution of symptoms over a longer period and the impacts of interventions will improve our understanding of the long-term impacts of the COVID-19 disease. This review will discuss the emerging evidence for the development of post-COVID interstitial lung disease focusing on the pathophysiological mechanisms, incidence, diagnosis, and impact of this potentially new and emerging respiratory disease.

Does the Prosthetic Phase of Dental Implants Justify the Prescription of Preventive Antibiotics in Healthy Patients? A Systematic Review.

Recently published surveys data show that the routine prescription of preventive antibiotics (PA) in the prosthetic phase of dental implants is more common than might be expected. The present study aimed to answer the PICO (population, intervention, comparison, and outcome) question "In healthy patients starting the implant prosthetic phase, does the prescription of PA compared with not prescribing PA decrease the incidence of infectious complications?" by a systematic literature review. A search was performed in 5 databases.

Restoring the functionality of implant-supported prostheses with a reloading technique: A clinical report.

The prevalence of infraocclusion and/or loss of interproximal contact areas with implant-supported restorations is high, and replacement of these prostheses has been advocated for the treatment of mild or moderate infraocclusion; however, replacement is complicated if the manufacturer of the implant is unknown. A technique is presented for correcting the infraocclusion of posterior prostheses that are directly connected to the implant. Advantages include possibly preventing marginal bone loss secondary to the removal and reconnection of the prosthetic attachments and reducing the number of appointments.

Recently, the Spanish Society of Implants (SEI) developed the first clinical practice guidelines published to date, providing clear guidelines on how to prescribe responsible and informed preventive antibiotic therapy (PAT) based on the available scientific evidence on dental implant treatments (DIs). The present document aims to summarise and disseminate the recommendations established by this expert panel.

The use of platelet-rich fibrin in vestibuloplasty: A 36-month follow-up technique report.

Introduction: Vestibuloplasty is a mucogingival procedure that aims to increase the vestibule and the amount of keratinized tissue (KT) around teeth and dental implants. Currently, the gold standard in this procedure is still represented by free gingival grafts (FGGs); however, they require a second surgical site, which means more morbidity for the patient and a higher risk of surgical complications, as well as surgical time and chromatic alteration of the recipient area.

Case Presentation: This is a description of the vestibuloplasty technique with platelet-rich fibrin (PRF) in a 35-year-old female patient with a thin gingival phenotype and no medical history of interest.

Treatment of oroantral communication with Platelet-Rich Fibrin: A systematic review.

Background: Oroantral communication (OAC) is the opening between the maxillary sinus and the oral cavity, which constitutes a gate for the mucosal infection in the maxillary sinus. On the other hand, an OAF develops when the OAC does not close spontaneously, remains manifest and is epithelialized. Several methods have been proposed to solve these situations, however, they are associated with increased postoperative morbidity and/or higher associated costs and require some experience of the surgeon to perform them.

Povidone-Iodine as a Pre-Procedural Mouthwash to Reduce the Salivary Viral Load of SARS-CoV-2: A Systematic Review of Randomized Controlled Trials.
