Physiology of neuroactive peptides in vertebrate retina.
ACh release but bicuculline markedly increased the spontaneous resting release, suggesting a tonic GABA-ergic input to the cholinergic amacrine cells (Cunningham & Neal, 1983). The GABA analogues muscimol and 3-APS also reduced the light-evoked release of ACh but were several thousand times more potent than GABA itself. The remarkably high relative potencies of the analogues might be due to the...
متن کاملmicroRNAs in vertebrate physiology and human disease.
Over the past five years, the importance of a diverse class of 18-24 nucleotide RNA molecules, known as microRNAs (miRNAs) has increasingly been recognized. These highly conserved RNAs regulate the stability and translational efficiency of complementary target messenger RNAs. The human genome is now predicted to encode nearly 1,000 miRNAs that likely regulate at least one third of all human tra...
متن کاملPhysiology of parturition
Labor is a physiological event involving a sequential, integrated set of changes within the myometrium, deciduas, and uterine cervix that occur gradually over a period of days to weeks. Biochemical connective tissue changes in the uterine cervix appear to precede uterine contractions and cervical dilation, and all of these events usually occur before rupture of the fetal membranes. In other wor...
متن کاملA generic organ based ontology system, applied to vertebrate heart anatomy, development and physiology
We present a novel approach to modelling biological information using ontologies. The system interlinks three ontologies, comprising anatomical, developmental and taxonomical information, and includes instances of structures for different species. The framework is constructed for comparative analyses in the field of evolutionary development. We have applied the approach to the vertebrate heart ...
متن کاملComparative Physiology of Energy Metabolism: Fishing for Endocrine Signals in the Early Vertebrate Pool
Energy is the common currency of life. To guarantee a homeostatic supply of energy, multiple neuro-endocrine systems have evolved in vertebrates; systems that regulate food intake, metabolism, and distribution of energy. Even subtle (lasting) dysregulation of the delicate balance of energy intake and expenditure may result in severe pathologies. Feeding-related pathologies have fueled research ...
