PepGAT, a chitinase-derived peptide, alters the proteomic profile of colorectal cancer cells and perturbs pathways involved in cancer survival.

Colorectal cancer (CRC) affects the population worldwide, occupying the first place in terms of death and incidence. Synthetic peptides (SPs) emerged as alternative molecules due to their activity and low toxicity. Proteomic analysis of PepGAT-treated HCT-116 cells revealed a decreased abundance of proteins involved in ROS metabolism and energetic metabolisms, cell cycle, DNA repair, migration, invasion, cancer aggressiveness, and proteins involved in resistance to 5-FU.

Unveiling degenerative bone changes in the condyle: a texture analysis approach using cone-beam computed tomography.

Purpose: The degenerative joint disease is a temporomandibular disorder. By analysing texture parameters, it becomes possible to characterize and differentiate various tissues, based on their textural properties according to cone-beam computed tomography (CBCT). This study evaluated degenerative diseases in the temporomandibular joint through texture analysis.

[Pharmacovigilance of COVID-19 Vaccines in Brazil: Actions Taken, Lessons Learned, and Next StepsFarmacovigilancia de las vacunas contra la COVID-19 en Brasil: medidas adoptadas, enseñanzas extraídas y próximos pasos].

Objective: To document the actions taken by Brazil's National Immunization Program for the pharmacovigilance of COVID-19 vaccines.

Methods: Documentary research on the period 2020 to 2023. Documentary sources from the national Ministry of Health during COVID-19 vaccination were used to analyze and interpret the actions taken.

2D Facial Analysis Performed by a Human Operator Versus an Artificial Intelligence Software.

Background: Artificial intelligence (AI) has been a contribution in recent years to the development of new tools for dental, surgical, and esthetic treatment. In the case of image diagnosis, AI allows automated analysis of some facial parameters. The aim of this study was to evaluate the precision and reproducibility of these IA analyses compared with a human operator.
