Introducción: El carcinoma adrenocortical es una entidad rara con incidencia anual de 1- 2 casos por millón personas. Las neoplasias oncocíticas que surgen en las glándulas suprarrenales son extremadamente raras, y lo general se descubren como tumores no funcionales su mayoría benignos. Objetivo: describir características clínico- epidemiológicas del tumor oncocítico hipersecretor corteza supra...

EDITORIAL COMMENT The association of duodenal ulcer with blood group 0 and salivary ABH non-secretion, and the apparent increased likelihood of bleeding in patients of blood group 0 with duodenal ulcer, are not understood. A new approach to the problem is provided by this carefully executed investigation which demonstrates an interaction between blood group and secretor status, and cell loss fr...

Noroviruses infect an estimated 21 million people annually and are a leading cause of acute gastroenteritis in the United States, making them a major health concern [1]. Despite the widespread prevalence of noroviruses, epidemiology of these viruses is poorly understood, even in the United States and European countries with active surveillance efforts. One critical factor that has been widely o...

We have examined 12 unlinked polymorphic genetic marker systems and found 6 which each identified small but statistically significant differences in normal serum cholesterol levels which did not change significantly with age. The effects associated with 4 of the 6-ABO. haptoglobin, Gm and secretor-were consistent in males and females and combined additively to define effects which were also hom...

Eight 2-deoxystreptamine-negative (DOS-) mutants were isolated from various strains of Bacillus circulans, normally producing butirosin, xylostasin and ribostamycin. These mutants were classified into two groups (converter and secretor) by the simple method of cosynthesis using agar plate culture. One of the cosynthetic pairs, strain S-11, an intermediate of DOS biosynthesis, S-11-P, was isolat...

The advent of hybridoma technology in 1975 (1) represented a quantum leap in the field of tumor immunology. For the first time, B-lymphocytes from immunized hosts could be immor talized by means of fusion with drug selected non-immunoglobulin secretor murine myeloma cells. These fused cell products could then be cloned and propagated indefinitely. The super natant fluids of cultures from litera...
