Germinative dynamic, seasonality, and polyandry: A dive in neotropical point-belly frog reproduction.

Complexity and reproductive plasticity are very well-known characteristics of anurans. The group is being continuously explored taxonomically and phylogenetically, which leads to a great potential diversity not yet uncovered. This is particularly evident due to the lack of investigation regarding species-specific traits, even the ones well distributed in the lineages as polyandry.

Morphology, glicohistochemistry and immunolocalization of Aquaporin 5 in the mandibular gland of the giant anteater (Myrmecophaga tridactyla).

Background: The giant anteater (Myrmecophaga tridactyla) is a toothless mammal that feeds mainly on termites and ants. Therefore, like other toothless mammals, this species has morphological and physiological adaptations of the salivary glands related to eating habits. Saliva is essential for the health of the oral cavity, chewing and lubrication of the mouth and it is constituted by an aqueous fluid containing electrolytes, enzymes, and glycoproteins which play an important role in modulating the oral microbiota.

Maternal protein restriction affects the differentiation of cells in the epididymal epithelium lining of 44-day-old rats.

Maternal protein restriction delays the differentiation of epididymal mesenchymal cells in newborn rats. However, it's unclear if this delay persists until the full differentiation of the epididymal epithelium at 44 days postnatal. Thus, this study aimed to assess the impact of maternal protein reduction on 44-day-old rats' epididymal epithelium differentiation, following up on the observed delay in newborn animals.

2,4-dichlorophenoxyacetic acid (2,4-D) exposure during postnatal development alters the effects of western diet on mouse prostate.

Western diet (WD), abundant in saturated fats and simple carbohydrates, has been associated with the development of prostate diseases. In addition, 2,4-dichlorophenoxyacetic acid (2,4-D), an herbicide used in agricultural and non-agricultural settings, may interfere with the endocrine system impacting reproductive health. The association of both factors is something common in everyday life, however, there are no relevant studies associating them as possible modulators of prostatic diseases.
