Complementary Actions of BDNF and Neurotrophin-3 on the Firing Patterns and Synaptic Composition of Motoneurons
(Society for Neuroscience, 2009)
Neurotrophins, as target-derived factors, are essential for neuronal survival during development, but during adulthood, their scope of actions widens to become also mediators of synaptic and morphological plasticity. Target ...

Hormonal Regulation of chicken intestinal NHE and SGLT-1 activities
(2001)
The effects of aldosterone and arginine vasotocin (AVT) on intestinal Na/Hexchange (NHE) and Na-sugar cotransport (SGLT-1) activi-ties have been investigated using brush-border membrane ves-icles isolated from Hubbard ...

Neuronal Premotor Networks Involved in Eyelid Responses: Retrograde Transneuronal Tracing with Rabies Virus from the Orbicularis Oculi Muscle in the Rat
(Society for Neuroscience, 2002)
Retrograde transneuronal tracing with rabies virus from the right orbicularis oculi muscle was used to identify neural networks underlying spontaneous, reflex, and learned blinks. The kinetics of viral transfer was studied ...

Regional differences in transport, lipid composition, and fluidity of apical membranes of small intestine of chicken
(Poultry Science Association, 2002)
Na+-dependent D-glucose transport was studied in brush-border membrane vesicles from duodenum, jejunum, and ileum of 5- to 6-wk-old chickens. Regional differences were found, and both initial rates and accumulation ratio ...

Ontogeny regulates creatine metabolism in rat small and large intestine
(2009)
The ontogeny of intestinal CRT, AGAT and GAMT was investigated in foetuses, newborn, suckling, weaning and adult rats. In the colon, CRT mediates creatine transport because it was Na+- and Cl—dependent and inhibited by ...

Regulation of Gephyrin Cluster Size and Inhibitory Synaptic Currents on Renshaw Cells by Motor Axon Excitatory Inputs
(Society for Neuroscience, 2005)
Renshaw cells receive a high density of inhibitory synapses characterized by large postsynaptic gephyrin clusters and mixed glycinergic/ GABAergic inhibitory currents with large peak amplitudes and long decays. These ...

Liver lipid composition and antioxidant enzyme activities of spontaneously hypertensive rats after ingestion of dietary fats (fish, olive and high-oleic sunflower oils)
(Portland Press, 2001)
Hypertension is associated with greater than normal lipoperoxidation and an imbalance in antioxidant status, suggesting that oxidative stress is important in the pathogenesis of this disease. Although many studies have ...

A Cholinergic Synaptically Triggered Event Participates in the Generation of Persistent Activity Necessary for Eye Fixation
(Society for Neuroscience, 2004)
An exciting topic regarding integrative properties of the nervous system is how transient motor commands or brief sensory stimuli are able to evoke persistent neuronal changes, mainly as a sustained, tonic action potential ...
