Interferon-γ (IFN-γ) is a key mediator in antitumor immunity and immunotherapy responses, yet its clinical application remains restricted to chronic granulomatous disease and malignant osteopetrosis. IFN-γ effectiveness as a standalone treatment has shown limited success in clinical trials and its potential for synergistic effects when combined with immunotherapies is under clinical exploration. A particularly compelling combination is that of IFN-γ with Toll-like receptor (TLR) agonists that holds significant promise for cancer treatment.

Background: Clonal mature B-cell lymphoproliferative disorders (B-LPDs) are a heterogeneous group of neoplasia characterized by the proliferation of mature B lymphocytes in the peripheral blood, bone marrow and/or lymphoid tissues. B-LPDs classification into different subtypes and their diagnosis is based on a multiparametric approach. However, accurate diagnosis may be challenging, especially in cases of ambiguous interpretation.

Background: Red Blood Cell Exchange (RBCX) is a common treatment for pediatric sickle cell disease (SCD). Since inflammation with elevated proinflammatory cytokines plays a crucial role in SCD, this study hypothesized that RBCX might lower these cytokines and aimed to assess the impact of this technique on these markers.

Methods: Prospective and observational study of pediatric SCD patients (HbSS genotype) enrolled in a chronic RBCX program at a Portuguese Hospital from October 2022 to August 2024.

This study aimed to evaluate the effects of sunflower cake (SFC) levels (0, 7, 14, 21, and 28% dry matter) in the diet for feedlot lambs on meat quality and its fatty acid profile. Forty crossbreed non castrated hair lambs were fed with experimental diets through 70 days when they were slaughtered and a Longissimus lumborum section were evaluated for physicochemical quality and fatty acid profile. There were no effects of SFC levels (P > 0.
