Daidzein and Equol: Ex Vivo and In Silico Approaches Targeting COX-2, iNOS, and the Canonical Inflammasome Signaling Pathway.

Background: The inflammasome is a cytosolic multiprotein complex associated with multiple autoimmune diseases. Phytochemical compounds in soy () foods, such as isoflavones, have been reported for their anti-inflammatory properties.

Aim: the anti-inflammatory activity of DZ (daidzein) and EQ (equol) were investigated in an ex vivo model of LPS-stimulated murine peritoneal macrophages and by molecular docking correlation.

Dietary oleacein, a secoiridoid from extra virgin olive oil, prevents collagen-induced arthritis in mice.

Olacein (OLA), one of the main secoiridoids derived from extra virgin olive oil (EVOO), has been shown to modulate oxidative and inflammatory responses in various pathological conditions; however, its potential benefit in joint disorders such as rheumatoid arthritis (RA) is unknown. Therefore, this study was designed to evaluate the preventive role of the effects of an OLA-supplemented diet in the murine model of collagen-induced arthritis (CIA), delving into the possible mechanisms and signaling pathways involved. Animals were fed an OLA-enriched preventive diet for 6 weeks prior to CIA induction and until the end of the experimental time course.

Pharmacological hyperprolactinemia: a retrospective analysis of 501 hyperprolactinemia cases in primary care setting.

Purpose: To describe a series of cases with pharmacological hyperprolactinemia in primary care setting and the prolactin levels, clinical implications of different causes of pharmacological hyperprolactinemia.

Methods: A retrospective study of all patients with detected hyperprolactinemia in hormonal studies was performed between 2019 and 2020 in 20 Spanish primary care centers. Hyperprolactinemia is defined as a serum prolactin >19.

Unravelling hip-spine bone mineral density discordance in people living with HIV.

Introduction: In people living with HIV (PLWH), bone mineral density (BMD) discordance between the lumbar spine (LS) and femoral neck (FN) could be frequent given the high frequency of secondary osteoporosis, including HIV-related factors for bone disease.

Materials And Methods: Retrospective cohort of PLWH with a dual X-ray absorptiometry scan. Hip-spine BMD discordance was defined as different T-score or Z-scores categories at LS and FN.

CD4 and CD8 T-cell responses in bone marrow to fatty acids in high-fat diets.

Obesity is associated with disruptions in the adaptive immune system; however, dietary fatty acids in high-fat diets (HFDs) that induce obesity have consequences that are currently unclear regarding T-cell maintenance in bone marrow (BM). C57BL/6J mice were randomly assigned to isocaloric HFDs formulated with dietary fats rich in saturated fatty acids (SFAs), monounsaturated fatty acids (MUFAs), or MUFAs supplemented with eicosapentaenoic and docosahexaenoic acids for 20 weeks, followed by an analysis of the immunophenotypic feature of lymphocytes (CD3) T and their subsets CD4 and CD8 T cells in spleen and BM, identification of fatty acids in BM extracellular fluid and analysis of the correspondence between fatty acids with the frequency of T-cell subsets in BM. Splenic CD3 T cells were reduced irrespective of HFDs.
