Burnout (BO) is a response to prolonged exposure to work-related stressors characterized by emotional exhaustion (EE), depersonalization (DP), and reduced personal accomplishment (PA). The police working environment includes continued critical life-threatening situations, violence, and injuries, among other related factors putting them at high risk of distress. The objective of this study was to evaluate the association between Burnout Syndrome and sociodemographic, occupational, and health factors in Mexican police officers.

Galectins are animal lectins that bind to β-galactosides, such as lactose and N-acetyllactosamine, contained in glycoproteins or glycolipids. Galectin-1 (Gal-1) and Galectin-3 (Gal-3) are involved in pathologies associated with the inflammatory process, cell proliferation, adhesion, migration, and apoptosis. Recent evidence has shown that the administration of Amyloid-β 25-35 (Aβ) into the hippocampus of rats increases the inflammatory response that is associated with memory impairment and neurodegeneration.

Introduction: Living with dogs leads one to consider the necessity of identifying canine infections found in the people with whom the dogs live.

Objective: Dogs which were clinically and serologically positive with the infections Ehirlichia canis, Anaplasma phagocytophilum, Borrelia burgdorferi, and Dirofilaria Immitis were sought. People with the same infections were also identified.

Article Synopsis
  • The study investigates how the cytotoxic protein Aβ(25-35) affects inflammatory markers and heat shock proteins in rat C6 astrocyte cells.
  • Treatment with Aβ(25-35) significantly increased levels of IL-1β, TNF-α, and nitrite after three days, indicating an inflammatory response.
  • Hsp-70 expression peaked at three days but subsequently dropped, while Hsp-60 and Hsp-90 expressions continued to rise, suggesting a complex relationship between these proteins and cell death during Aβ(25-35) exposure.

Background: Fibroadenomas are benign human breast tumors, characterized by proliferation of epithelial and stromal components of the terminal ductal unit. They may grow, regress or remain unchanged, as the hormonal environment of the patient changes. Expression of antigen TF in mucin or mucin-type glycoproteins and of galectin-3 seems to contribute to proliferation and transformations events; their expression has been reported in ductal breast cancer and in aggressive tumors.

Sialic acid in glycoconjugates participates in important cellular functions associated with normal development, growth, and communication. Therefore we evaluated the sialylation pattern and memory deficits caused by the injection of Aβ((25-35)) into the hippocampus (Hp) of rats. The eight-arm maze spatial-learning and memory test indicated that the injection of Aβ((25-35)) into subfield CA1 of the Hp impaired both learning and memory.

Prion diseases are caused by an abnormal form of the prion protein (PrP(Sc)). We identified, with lectins, post-translational modifications of brain proteins due to glycosylation in a Gerstmann-Sträussler-Scheinker (GSS) patient. The lectin Amaranthus leucocarpus (ALL), specific for mucin type O-glycosylated structures (Galß1,3 GalNAcα1,0 Ser/Thr or GalNAcα1,0 Ser/Thr), and Sambucus nigra agglutinin (SNA), specific for Neu5Acα2,6 Gal/GalNAc, showed positive labeling in all the prion deposits and in the core of the PrP(Sc) deposits, respectively, indicating specific distribution of O-glycosylated and sialylated structures.
