Short-Latency Trigeminocervical Reflex Obtained Without Muscle Activation: Topographic Distribution and Methodological Approach.

Purpose: Electrical stimulation of trigeminal nerve branches elicits early and late reflex responses in the cervical muscles, known as the trigeminocervical reflex (TCR). This study aimed to evaluate the neurophysiological aspects, stimulation patterns, and topographic distribution of short-latency TCR components in humans in the absence of voluntary muscle activation.

Methods: This prospective observational study included 30 participants.

Transcriptional responses of blastospores after UV-B irradiation.

is widely known for its role as an arthropod biocontrol agent and plant bioinoculant. By using mass-production industrial methods, it is possible to produce large amounts of fungal single-celled propagules (including blastospores) to be applied in the field. However, in the environment, the solar ultraviolet components (particularly UV-B) can harm the fungus, negatively impacting its pathogenicity toward the arthropod pest.

Genetic and biochemical determinants in potentially toxic metals resistance and plant growth promotion in Rhizobium sp LBMP-C04.

The association of bacteria resistant to potentially toxic metals (PTMs) with plants to remove, transfer, or stabilize these elements from the soil is an appropriate tool for phytoremediation processes in metal-contaminated environments. The objective of this study was to evaluate the potential of Rhizobium sp. LBMP-C04 for phytoremediation processes and plant growth promotion in metal-contaminated soils.

Inhibition of furin in CAR macrophages directs them toward a proinflammatory phenotype and enhances their antitumor activities.

Chimeric antigen receptor (CAR)-T-cell therapy has revolutionized cellular immunotherapy, demonstrating remarkable efficacy in hematological cancers. However, its application in solid tumors faces significant challenges, including limited T-cell infiltration and tumor-induced immunosuppression. Given the prominent role of macrophages in the tumor microenvironment, their phenotypic plasticity and inherent antitumor properties, such as phagocytosis, offer a promising avenue for therapeutic intervention.

Two Years Post-COVID-19: An Ecologic Study Evaluating the Impact on Brazil's Mammographic Screening Program.

Objectives: The objective of this study was to assess the impact of the COVID-19 pandemic, after 2 years, on mammographic screening in Brazil evaluating BIRADS® results, breast cancer diagnosis rates, and breast cancer stage.

Study Design: This was an ecological observational study based on retrospective data from Brazil's mammographic screening program from 2015 to 2023.

Methods: Data were obtained from the national screening database DATASUS - SISCAN (Cancer System Information) and retrieved in March 2024.
