BACKGROUND Dehydration from viral gastroenteritis is a significant pediatric health problem. Oral rehydration therapy (ORT) is recommended as first-line therapy for both mildly and moderately dehydrated children; however, three quarters of pediatric emergency medicine physicians who are very familiar with the American Academy of Pediatrics recommendations for ORT still use intravenous fluid the...

We establish that the sequences formed by logarithms and by “fractional” powers of integers, as well as the sequence of prime numbers, are non-holonomic, thereby answering three open problems of Gerhold [El. J. Comb. 11 (2004), R87]. Our proofs depend on basic complex analysis, namely a conjunction of the Structure Theorem for singularities of solutions to linear differential equations and of a...

Francisco Ort-Llorca (1905-1993) was one of the most outstanding Spanish embryologists of the XX century. He was disciple of Henri Rouvire in Paris (France), Alfred Fischel in Vienna (Austria), Walther Vogt in Munich (Germany) and Pedro Ara in Madrid (Spain). From 1935, he was professor of Human Anatomy at the Faculty of Medicine of Cadiz, belonged then to the University of Seville (accidentall...

PURPOSE To investigate outer retinal tubulation (ORT) using spectral domain optical coherence tomography (SD-OCT) and an adaptive optics scanning laser ophthalmoscope (AOSLO). To document the frequency of ORT in atrophic retinal conditions and quantify ORT dimensions versus adjacent retinal layers. METHODS SD-OCT images were reviewed for the presence of retinal atrophy, scarring, and/or exuda...

BACKGROUND To evaluate the choice and utility of pacing maneuvers in the electrophysiology (EP) laboratory in establishing supraventricular tachycardia (SVT) mechanism. METHODS We retrospectively examined a cohort of 160 consecutive patients with SVT presenting for invasive EP evaluation to a single center with 8 electrophysiologists. We analyzed the utility of the two most commonly used paci...

A key tool in neuroscience is the ability to transiently inactivate specific neurons on timescales of milliseconds to minutes. In Drosophila, there are two available techniques for accomplishing this (shibire(ts) and halorhodopsin [1-3]), but both have shortcomings [4-9]. Here we describe a complementary technique using a native histamine-gated chloride channel (Ort). Ort is the receptor at the...

A hospital based case-control study for assessing the effectiveness of oral rehydration therapy (ORT) preparation against severe dehydration due to diarrhea was conducted at the Infectious Diseases Hospital, Jakarta, Indonesia. A total of 202 children aged 24 months or less who attending the hospital were suffering from acute watery diarrhea were recruited in the study. Those who were severely ...
