Localized cytosolic alkalization and its functional impact in ciliary cells.

Using confocal microscopy we demonstrate that ciliary cells from airway epithelium maintain two qualitatively distinct cytosolic regions in terms of pH regulation. While the bulk of the cytosol is stringently buffered and is virtually insensitive to changes in extracellular pH (pHo), the values of cytosolic pH in the vicinity of the ciliary membrane is largely determined by pHo. Variation of pHo from 6.

Analyzing spatial coherence using a single mobile field sensor.

According to the Van Cittert-Zernike theorem, the intensity distribution of a spatially incoherent source and the mutual coherence function of the light impinging on two wave sensors are related. It is the comparable relationship using a single mobile sensor moving at a certain velocity relative to the source that is calculated in this paper. The auto-corelation function of the electric field at the sensor contains information about the intensity distribution.

[Epidemiologic study about the variation of the demand in mental health in the last two decades].

We have investigated age, sex, nationality, origin, diagnosis and treatment types in ambulatory patients of the External Clinics of the Division Health Mental of the General Hospital for Acute Patients "Dr. Teodoro Alvarez", of 600 Clinical Histories obtained in the years 1980, 1990 and 2000. These data have been extracted with the purpose of studying probable changes in the social and psychopathologic conformation of the patients, in the last two decades.
