Assuming three-neutrino mixing and massive Majorana neutrinos, we study the implications of the neutrino oscillation solutions of the solar and atmospheric neutrino problems and of the results of the CHOOZ experiment for the predictions of the effective Majorana mass in neutrinoless double beta ((ββ) 0ν-)decay, |< m >|. The general case of CP-nonconservation is investigated. The predicted value...

The phenomenological theory of spin thermodynamics based on the spin temperature hypothesis was employed to describe the cross-polarization (CP) dynamics between two abundant nuclei, (19)F and (1)H, when the number of fluorine atoms is not substantially less than the number of hydrogens. The influence of T(1rho)'s of both nuclei and the relative magnitude (heat capacity) of the two spin baths m...

Measurements of the CKM angle β in charmless loop-dominated B meson decays at BABAR Abstract We report on preliminary measurements of time-dependent CP-violation asymmetries in charmless neutral B meson decays to K +

Central Pontine Myelinosis (CPM) and Extra Pontine Myelinosis (EPM) are debilitating conditions, resulting from the rapid correction of hyponatremia. The outcome and prognosis of this medical condition are variable; mainly involving functional decline from neuro-musculoskeletal upset. An intensive, multidisciplinary rehabilitation has played an essential role in facilitating and hasten recovery...

ACh regulates arousal, and the present study was designed to provide insight into the neurochemical mechanisms modulating ACh release in the pontine reticular formation. Nitric oxide (NO)-releasing beads microinjected into the pontine reticular formation of C57BL/6J (B6) mice significantly (P < 0.0001) increased ACh release. Microdialysis delivery of the NO donor N-ethyl-2-(1-ethyl-2-hydroxy-2-...

In a case of acute disseminated encephalomyelitis displaying opsoclonus-myoclonus syndrome, magnetic resonance images (MRI) disclosed pontine lesions involving part of the pontine paramedian reticular formation and the raphe nucleus. Shrinkage of the lesions correlated with the patient's clinical state. This observation supports the hypothesis that a pontine lesion can cause opsoclonus-myoclonu...

Progressive motor deficits are relatively common in acute pontine infarction and frequently associated with increased functional disability. However, the factors that affect the progression of clinical motor weakness are largely unknown. Previous studies have suggested that pontine infarctions are caused mainly by basilar artery stenosis and penetrating artery disease. Recently, lower pons lesi...

Central pontine myelinolysis can occur after orthotopic liver transplantation leading to high mortality and serious morbidity. In our case, central pontine myelinolysis was associated with wide fluctuations in cyclosporine levels during an episode of hypocholesterolaemia, which may have precipitated central pontine myelinolysis.

Acetylcholine (ACh) regulates arousal and the present study was designed to provide insight into the neurochemical mechanisms modulating ACh release in the pontine reticular formation. Nitric oxide-releasing beads microinjected into the pontine reticular formation of C57BL/6J (B6) mouse caused a significant (p<0.0001) increase in ACh release. Microdialysis delivery of the nitric oxide donor NOC...
