How a responsive reproduction factor is determinant in a prey-predator dynamics: A numerical and analytical study in a discrete-time model.

In this work, we investigate the dynamics of a discrete-time prey-predator model considering a prey reproductive response as a function of the predation risk, with the prey population growth factor governed by two parameters. The system can evolve toward scenarios of mutual or only of predators extinction, or species coexistence. We analytically show all different types of equilibrium points depending on the ranges of growth parameters.

Melatonin influence on miRNA expression in sperm, hypothalamus, pre-frontal cortex and cerebellum of Wistar rats.

Melatonin is a pineal hormone synthesized exclusively at night, in several organisms. Its action on sperm is of particular interest, since they transfer genetic and epigenetic information to the offspring, including microRNAs, configuring a mechanism of paternal epigenetic inheritance. MicroRNAs are known to participate in a wide variety of mechanisms in basically all cells and tissues, including the brain and the sperm cells, which are known, respectively, to present 70% of all identified microRNAs and to transfer these molecules to the embryo.

The C and KP groups received 1 mL of water/day; KL dams received kefir milk daily (10 CFU/mL) during lactation.

Retained versus removed copper intrauterine device during pregnancy: An updated systematic review and meta-analysis.

Introduction: Intrauterine devices (IUDs) are highly effective contraceptives. Despite their effectiveness, pregnancies can occur during IUD use, and the management of such cases, particularly when the pregnancy is desired, remains controversial.

Material And Methods: We conducted a systematic review and meta-analysis to evaluate outcomes in women who unintentionally conceived while using IUDs and chose to continue their pregnancies.

Decision Trees for the Recognition of Metal-Centered Chirality in Coordination Complexes.

While established guidelines exist for chirality in tetrahedral molecules, there is a notable absence of clear rules for recognizing metal-centered chirality in higher-coordination complexes. We develop decision trees to assess the likelihood of chirality-at-metal in coordination complexes with coordination numbers 4-9 with mono and bidentate ligands. Using binary decision rules based on shape, ligand type, and quantity, the trees classify complexes as chiral or achiral.
