The aims of this survey were to determine the flock-level and animal-level prevalences of anti-Toxoplasma gondii antibodies in sheep in the State of Paraíba, Northeastern Brazil, and to identify risk factors. Blood samples were collected from 540 sheep in 63 flocks in 14 municipalities in the Sertão mesoregion. To serologically diagnose T. gondiii nfection, the indirect immunofluorescent antibody test (IFAT) was used. Flocks with at least one seropositive animal were considered positive. Among the 63 flocks, 28 (44.44%) were positive, and 60 (11.11%) of the 540 animals were seropositive. Variable flock size > 25 animals was identified as a risk factor (odds ratio = 3.2; 95% CI = 1.09 - 9.34; P = 0.033). The results from this survey demonstrate that T. gondii is spread among sheep in the State of Paraíba.

The integration of psychedelic substances into modern Western therapeutic practice has sparked a critical examination of many topics including: efficacy of psychedelics to treat mental health diagnoses without psychotherapeutic intervention, what models of therapy to use, and ethical implications related to altered states of consciousness. Of utmost concern are issues of power dynamics leading to incidents of sexual abuse. These issues underscore the importance of understanding therapeutic dynamics within the context of psychedelic-assisted therapy.

Melanoma is among the most common malignancies and has recently exhibited increased resistance to treatments, resulting in a more aggressive disease course. Mesenchymal stem cells (MSCs) secrete cytokines both in vivo and in vitro, which regulate tumor cell signaling pathways and the tumor microenvironment, thereby influencing tumor progression. This study investigates the anti-melanogenesis effects of sheep umbilical cord mesenchymal stem cells (SUCMSCs) to assess their potential application in melanoma treatment.

Soil-Plant Characterization in Agrosilvopastoral System Established in a Fe-Mn Abandoned Mine After Long-Term Closure.

Small abandoned mining areas of Fe and Mn oxides located in the Portuguese sector of the Iberian Pyrite Belt (SW of Europe) have been converted into agrosilvopastoral systems with very few environmental management measures after their closure. Although at the landscape scale, no visible differences were observed between the former mining intervention areas and adjacent areas, it is essential to assess the state and environmental risk of the soil-plant system, especially in the herbaceous pastures grazed by domestic animals. This was carried out in the Ferragudo mining area, where an agrosilvopastoral system, composed of holm oak and dryland pasture, had been established after the closure of the mine at ≈45 years.
