Longitudinal anti-SARS-CoV-2 antibody immune response in acute and convalescent patients.

Despite global efforts to assess the early response and persistence of SARS-CoV-2 antibodies in patients infected with or recovered from COVID-19, our understanding of the factors affecting its dynamics remains limited. This work aimed to evaluate the early and convalescent immunity of outpatients infected with SARS-CoV-2 and to determine the factors that affect the dynamics and persistence of the IgM and IgG antibody response. Seropositivity of volunteers from Mexico City and the State of Mexico, Mexico, was evaluated by ELISA using the recombinant receptor-binding domain (RBD) of the SARS-CoV-2 Spike protein for 90 days, at different time points (1, 15, 45, 60, and 90 days) after molecular diagnosis (RT-qPCR).

Amoebiasis: Advances in Diagnosis, Treatment, Immunology Features and the Interaction with the Intestinal Ecosystem.

This review of human amoebiasis is based on the most current knowledge of pathogenesis, diagnosis, treatment, and Entamoeba/microbiota interactions. The most relevant findings during this last decade about the parasite and the disease are related to the possibility of culturing trophozoites of different isolates from infected individuals that allowed the characterization of the multiple pathogenic mechanisms of the parasite and the understanding of the host-parasite relationship in the human. Second, the considerable advances in molecular biology and genetics help us to analyze the genome of , their genetic diversity, and the association of specific genotypes with the different amoebic forms of human amoebiasis.

Sexism and sexual risk behavior in adolescents: Gender differences.

: This study examines whether there are differences in the maintenance of ambivalent sexist beliefs on the basis of gender and sexual experience in adolescents. The study also investigates whether the sexist beliefs themselves are linked to sexual risk behaviors. : A representative sample of 2,703 Spanish adolescents was carried out in public and private secondary schools, with an age range of 14 to 20 years old ( = 15.

Antidiabetic, cytotoxic and antioxidant activities of oil extracted from pulp.

This study evaluated the hypoglycemic effect of the oil extracted from the pulp (OPAC) in normoglycemic rats and streptozotocin (STZ), fructose-induced diabetic rat models and its antioxidant and cytotoxic potential. OPAC (3, 30 300 mg/kg, v.o.
