Lead (Pb) exposure during perinatal development alters testosterone (T) concentrations and delays puberty in children and laboratory rodents. In addition, exposure to the metal during adult life decreases T and libido in men and affects male reproductive behaviour (MRB) in rats. MRB is regulated by various brain nuclei including the medial preoptic area (MPOa) and the medial amygdala (MeA), in which T and oestradiol (E) act through their respective androgen (AR) and oestrogen (ER) receptors.

Rationale: Corticosteroid-responsive type 2 (T2) inflammation underlies the T2-high asthma endotype. However, we hypothesized that type 1 (T1) inflammation, possibly related to viral infection, may also influence corticosteroid response.
Objectives: To determine the frequency and within-patient variability of T1-high, T2-high, and T1/T2-high asthma endotypes and whether virally influenced T1-high disease influences corticosteroid response in asthma.
Cadmium (Cd) is a toxic heavy metal widely distributed in foodstuffs. In Mexico, few studies have evaluated Cd content in foods. This study aimed to determine Cd concentrations in foodstuffs that are highly consumed and bought in Mexico City to identify foods exceeding the Maximum Level (ML) and to assess the health risks of theoretical Cd intake from a diet following the Mexican Dietary Guidelines.

In addition to its well-documented capacity to mitigate inflammation, IL-10 can unexpectedly demonstrate pro-inflammatory characteristics under specific circumstances. The presence of both aspects emphasizes the vital need to identify the IL-10-induced peptide.
