Enhanced immune function does not depress reproductive output

Enhanced Ovarian Folliclular Development by Metformin Does Not Correlate with Pregnancy Rate: A Randomized Trial

Does body volume constrain reproductive output in lizards?

The numbers and sizes of eggs produced by adult females ultimately determine the viability of populations, as well as the evolutionary fitness of the females themselves. Despite an enormous amount of literature on the adaptive significance of fecundity variation within and among populations, simpler questions--such as the proximate mechanisms by which a female determines her clutch size--have a...

Leptin, but not immune function, is linked to reproductive responsiveness to photoperiod.

Energetic demands are high while energy availability is minimum during winter. To cope with this energetic bottleneck, animals exhibit numerous energy-conserving adaptations during winter, including changes in immune and reproductive functions. A majority of individual rodents within a population inhibits reproductive function (responders) as winter approaches. A substantial proportion of small...

Xenon and nitrous oxide do not depress cardiac function in an isolated rat heart model.

PURPOSE To examine the inotropic and chronotropic effects of xenon (Xe) and nitrous oxide (N2O) compared with nitrogen (N2) on isolated rat hearts. The differences between Xe and N2O were also compared. METHODS The effects of Xe, N2O and N2 on coronary perfusion pressure (CPP), heart rate, left ventricular developed pressure (LVDP) and double product (DP) were examined in isolated rat hearts ...

Reality Does Not Recognize Borders

Reality does not recognize borders. Why we should use the very general term of “reality” and not science, because the borders that we draw are pure delusions, and on the opposite side there is the reality. The laws of the universe, either the physical nature of the world which the scientist studies or metaphysics which is the territory of philosophers, it isthe same reality that rules. Today ma...
