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).

Myofascial force transmission between latissimus dorsi and contralateral gluteus maximus in runners: a cross-sectional study.

The anatomical connection between latissimus dorsi (LD), thoracolumbar fascia, and contralateral gluteus maximus (GM) enables myofascial force transmission (MFT) between the shoulder, trunk, and hip. This study investigates whether regular sports practice, specifically running, influences this MFT pathway. Given the potential changes in tissue stiffness from sports practice and the importance of this property for MFT, we hypothesize that runners may exhibit greater MFT between the LD and GM, resulting in altered passive properties of the lumbar and hip regions during LD contraction.

Rescuing pathogen-specific memory B-cell from PBMC of prior Zika virus-infected individuals.

Immunological memory, a fundamental immune system mechanism, is instrumental in long-term protection. Successful vaccines can elicit and sustain immunological memory against pathogens for the long term. Memory B cells (MBC) are key players in secondary responses due to their longevity and rapid differentiation into high-affinity antibody-secreting cells upon second antigen exposure.

The use of dietary isotopes as a preliminary step in the death investigation of unidentified skeletal human remains in British Columbia, Canada.

In British Columbia, Canada, unidentified skeletal human remains are often recovered by law enforcement or civilians and there is a question if they are modern and of medicolegal significance, or historical or archaeological. We used relatively fast and inexpensive carbon and nitrogen stable isotope analysis of human bone collagen from a selection of these remains (n = 48) combined with a logistic regression model to classify remains as modern, historical, or archaeological. We then confirmed our temporal classification through directly radiocarbon dating each individual and found that we could predict the temporal group with 93% accuracy.
