Although the clinical and epidemiologic features of progressive disseminated histoplasmosis (PDH) in the acquired immunodeficiency syndrome (AIDS) have been well described, the pathologic and pulmonary aspects remain to be fully defined. A retrospective review of three patients and a prospective study of four more with PDH and AIDS recently admitted to an(More)
This study explores the application of neural network-based heuristics to the class/teacher timetabling problem (CTTP). The paper begins by presenting the basic CTTP characteristics in terms of hard and soft constraints and proposing a formulation for the energy function required to map the problem within the artificial neural network model. There follow(More)
The present study was conducted in order to analyze the relationship existing between leptin, insulin and neuropeptide Y (NPY) levels in massive weight loss and weight recovery. Twenty-three patients with severe obesity, 23 patients with anorexia nervosa and 28 healthy control subjects were studied. Patients with severe obesity underwent a vertical banded(More)
OBJECTIVES Describe the epidemiological characteristics of neonatal deaths in Peru. MATERIALS AND METHODS Descriptive study based on notifications to the Perinatal and Neonatal National Epidemiological Surveillance Subsystem (PNNESS) made in 2011-2012. The capture-recapture method was used to calculate the registration of the notification and estimate the(More)
The present study was conducted in order to analyze the relationship existing between leptin and insulin levels in massive weight loss and weight recovery. Thirteen patients with severe obesity, 14 patients with anorexia nervosa and 13 healthy control subjects were studied. The patients with severe obesity underwent a vertical banded gastroplasty followed(More)
Is well known that food can affect the bioavailability of several drugs, its impact is major for those drugs that have to act near of drug absorption. Documentation about alterations of ranitidine bioavailability by effect of food is poor. The purpose of this work was to evaluate the effect of food over the bioavailability of ranitidine. Twenty healthy(More)
Course Timetable Problem (CTTP) is considered as a multiassignments problem. This problem occurs during the assignment of a set of events (courses, subjects and teachers) to specific number of appointments (timeslots, days and rooms) under a set of hard and soft constraints. In this paper, the proposed algorithm is represented for solving the CTTP based on(More)
