During all periods of male ontogenesis, physiological processes responsible for the correct functioning of reproductive organs and spermatogenesis are under the influence of various factors (neuro-humoral, genetic, and paratypical). Recently, the attention of researchers has increasingly turned to the study of epigenetic factors. In scientific publications, one can increasingly find references to the direct role of microRNAs, small non-coding RNAs involved in post-transcriptional regulation of gene expression, in the processes of development and functioning of reproductive organs.

Two 35-day trials were conducted to determine the arginine (Arg) requirement of broiler chickens and the Arg and energy-sparing effects of guanidinoacetic acid (GAA). In experiment 1, a low-Arg diet (basal diet) was supplemented with increasing levels (0.06-0.

Bird nests of coastal or inland breeding birds can temporarily flood during high tides or storms. However, respiratory physiological disruption of such water submersion and implications for post-submergence survival are poorly understood. We hypothesized that respiratory physiological disturbances caused by submersion would be rapidly corrected following return to normal gas exchange across the eggshell, thus explaining survival of nest inundation in the field.

A 9-week-old male umbrella cockatoo () presented with mandibular prognathism. The rostral rhinothecal tomial length appeared subjectively shorter than the rostral gnathothecal length, which was subjectively rostrally elongated. After an initial orthosis failed, a second orthosis was designed that employed the use of an orthopedic wire anchor in the rostral end of the rhinotheca, leaving the premaxillary bone undisturbed.
