Effects of cyclic adenosine 3,5-monophosphate on photoreceptor disc shedding and retinomotor movement. Inhibition of rod shedding and stimulation of cone elongation. [PDF]
As a test of the hypothesis that cyclic nucleotides play a role in the regulation of retinomotor movements and disc shedding in the photoreceptor-pigment epithelial complex, we have used an in vitro eyecup preparation that sustains both disc shedding and

The ever unfolding story of cAMP signaling in trypanosomatids: vive la difference! [PDF]
Kinetoplastids are unicellular, eukaryotic, flagellated protozoans containing the eponymous kinetoplast. Within this order, the family of trypanosomatids are responsible for some of the most serious human diseases, including Chagas disease (Trypanosoma ...

Neural networks and support vector machines based bio-activity classification [PDF]
Classification of various compounds into their respective biological activity classes is important in drug discovery applications from an early phase virtual compound filtering and screening point of view. In this work two types of neural networks, multi

Compartmentalized PDE4A5 signaling impairs hippocampal synaptic plasticity and long-term memory [PDF]
Alterations in cAMP signaling are thought to contribute to neurocognitive and neuropsychiatric disorders. Members of the cAMP-specific phosphodiesterase 4 (PDE4) family, which contains >25 different isoforms, play a key role in determining spatial ...

Oral Phosphodiesterase Type 5 Inhibitors: Nonerectogenic Beneficial Uses
ABSTRACT Introduction Phosphodiesterase type 5 (PDE5) hydrolyses cyclic guanylate monophosphate (cGMP) specifically to 5′ GMP. PDE5 inhibitors were a breakthrough medication that addressed a previously unfulfilled medical need.

Activity of Cyclic AMP Phosphodiesterases and Adenylyl Cyclase in Peripheral Nerve after Crush and Permanent Transection Injuries [PDF]
Recent studies demonstrate that cAMP levels are tightly controlled during demyelination and remyelination in Schwann cells as cAMP decreases to 8–10% of normal following both sciatic nerve crush or permanent transection injury and only begins to increase
