What is the role and function of the tympanic membrane? What is the role, function, and structure of thalamus? (a) What is the hole in the center of the iris? (b) What is its function? What is the role and function of the rods and cones? What is the role, function, and structur...
What is the difference between rods and cones in the eye, particularly in regard to the fovea? What is the function of the periosteum? What is the function of the Eustachian tube? What is the function of capillaries? How is their structure and arrangement suited to their function?
Sixteen patients with UI were selected and underwent a complete PFR program (biofeedback, functional electrical stimulation, pelvic floor muscles exercises, and vaginal cones). Patient filled out the FSFI questionnaire and the KHQ at the baseline and at follow-up.Results. After PFR none of the ...
At sites matched for cone density (5,000 cones/mm 2 ), the mosaic is far more orderly in the temporal than in the nasal periphery. This is true at all ages and in both sexes. Despite their increased local order, regularity ratios of adjacent temporal fields tend to be much more ...
contains all their linear combinations αf1, + βf2, where α and β are real or complex numbers. An example of a linear function space is the spaceC(a, b) of all continuous functions on the interval[a, b]with the distance p(f1, f2) between two functions being given by the formula...
We also define the cones P~1={x∈X,x(t)≥γ~1(t)∥x∥,∀t∈[0,1]}⊂X,P~2={y∈X,y(t)≥γ~2(t)∥y∥,∀t∈[0,1]}⊂X, and P~=P~1×P~2⊂Y. For λ,μ > 0, we define now the operator Q~:P~→Y by Q~(x,y)=(Q~1(x,y),Q~2(x,y)) with ...
The Drosophila receptor guanylyl cyclase Gyc76C is required for semaphorin-1a-plexin A-mediated axonal repulsion. Cyclic nucleotide levels within extending growth cones influence how navigating axons respond to guidance cues. Pharmacological alteration of cAMP or cGMP ... Ayoob,C J. - 《Journal of ...
Axonal growth cones require an evolutionary conserved repulsive guidance system to ensure proper crossing of the CNS midline. In Drosophila, the Slit protein is a repulsive signal secreted by the midline glial cells. It binds to the Roundabout receptors, which are expressed on CNS axons in the lo...
