chronic constipation: no more idiopathic, but a true neuropathological entity
chronic constipation is still considered a functional or idiopathic disorder. however, in recent years there is evidence that its pathopysiological grounds may be actually due to a complex system of abnormalities of the enteric nervous system of these patients. in particular, as reported in this review, the enteric glial cells seem to be constantly involved in constipated patients, suggesting t...
متن کاملNot Strange but Bizarre Physics from the Sample Experiment
Since the report of the SAMPLE Collaboration suggesting the strange-quark contribution to the nucleon, G M (0), may be greater than zero, numerous models have appeared supporting positive values for G M (0). In this paper the bizarre physics associated with G M (0) > 0 is illustrated. Using new lattice QCD results, our best estimate for G M (0) shifts slightly from G M (0) = −0.75 ± 0.30 μN , t...

متن کاملHow strange a non-strange heavy baryon?
We give some general arguments in favor of the large magnitude of matrix elements of an operator associated with nonvalence quarks in heavy hadrons. We estimate matrix element 1 2mΛb 〈Λb|s̄s|Λb〉 ≃ 1 ÷ 2 for Λb baryon whose valence content is b, u, d quarks. This magnitude corresponds to a noticeable contribution of the strange quark into the heavy baryon mass 1 2mΛb 〈Λb|mss̄s|Λb〉 ≃ 200 ÷ 300MeV ....
