Preemptive vs preventive coadministration of ibuprofen L-arginine and dexamethasone in lower third molar surgeries: a randomized controlled trial.

Objective: To compare the effect of different preemptive and preventive analgesia strategies involving oral coadministration of ibuprofen-arginine (770 mg)-Ib-Ar and dexamethasone (8 mg)-DX, and their respective placebos (P-Ib-Ar and P-DX), four evaluation groups on inflammatory and laboratory parameters, impact on quality of life, pain catastrophizing perception and sleep quality related after lower third molar surgery.

Study Design: A randomized split-mouth, triple-blind, controlled clinical trial was conducted with 48 volunteers. They were allocated depending on the use of Ib-Ar or DX, 1 hour before surgery or immediately postoperatively, discriminating the groups: G1 (Ib-Ar + DX), G2 (Ib-Ar + P-DX), G3 (P-Ib-Ar + DX), and G4 (P-Ib-Ar + P-DX).

Improving the medium composition for the production of the natural blue-violet pigment violacein by a new Janthinobacterium sp. isolate.

The interest in natural compounds has increased primarily due to their beneficial health and environmental aspects. However, natural sources of some compounds, such as bluish pigments, are limited, requiring the development of efficient processes to meet commercial demands. This study isolated a blue-violet bacterium from spoiled cooked rice and identified it as a potential new species of Janthinobacterium through 16S rDNA analysis.

Is There an Interplay between Environmental Factors, Microbiota Imbalance, and Cancer Chemotherapy-Associated Intestinal Mucositis?

Interindividual variation in drug efficacy and toxicity is a significant problem, potentially leading to adverse clinical and economic public health outcomes. While pharmacogenetics and pharmacogenomics have long been considered the primary causes of such heterogeneous responses, pharmacomicrobiomics has recently gained attention. The microbiome, a community of microorganisms living in or on the human body, is a critical determinant of drug response and toxicity.

Inflammatory breast cancer microenvironment repertoire based on DNA methylation data deconvolution reveals actionable targets to enhance the treatment efficacy.

Background: Although the clinical signs of inflammatory breast cancer (IBC) resemble acute inflammation, the role played by infiltrating immune and stromal cells in this aggressive disease is uncharted. The tumor microenvironment (TME) presents molecular alterations, such as epimutations, prior to morphological abnormalities. These changes affect the distribution and the intricate communication between the TME components related to cancer prognosis and therapy response.

Diminazene aceturate inhibits the SARS-CoV-2 spike protein-induced inflammation involving leukocyte migration and DNA extracellular traps formation.

Aims: To investigate the SARS-CoV-2 Spike protein (Spk)-induced inflammatory response and its downmodulation by diminazene aceturate (DIZE).

Materials And Methods: Through inducing Spk inflammation in murine models, leukocyte migration to the peritoneum, levels of myeloperoxidase (MPO), malondialdehyde (MDA), rolling and adhesion of mesenteric leukocytes, and vascular permeability were investigated. Extracellular DNA traps (DETs) induced by Spk and the production of IL-6 and TNF-α were analyzed using human neutrophils, monocytes, and macrophages.
