Computation of the basic reproduction numbers for reaction-diffusion epidemic models

Mathematical biosciences and engineering : MBE, 2023
We consider a class of k-dimensional reaction-diffusion epidemic models (k=1,2,⋯) that are developed from autonomous ODE systems. We present a computational approach for the calculation and analysis of their basic reproduction numbers.

The Reproductive Revolution [PDF]

The Sociological Review, 2009
We suggest that a third revolution alongside the better known economic and political ones has been vital to the rise of modernity: the reproductive revolution, comprising a historically unrepeatable shift in the efficiency of human reproduction which for the first time brought demographic security.

Endocannabinoids and Reproduction [PDF]

International Journal of Endocrinology, 2014
Infertility is a worldwide reproductive health problem whose consequences have deep psychological and social impact in health, demographic change, and wellbeing. Thus, the knowledge of basic, conserved modulators of reproduction might contribute to the discovery of new potential target for the exploitation of drugs to treat infertility in humans ...

Bull spermatozoa selected by thermotaxis exhibit high DNA integrity, specific head morphometry, and improve ICSI outcome

Journal of Animal Science and Biotechnology, 2023
Background Sperm migration by thermotaxis is a guidance mechanism that operates along the oviduct and it has proved to be a valid method for selecting spermatozoa with low DNA fragmentation (SDF) in mice, humans, and stallions.
