The metabolic contributions to chronic acid-base changes were examined in the plasma of arterial blood in patients with chronic obstructive pulmonary disease (COPD) and chronic hypercapnia, by a quantitative physical-chemical analysis. Patients were stratified into three groups: group 1 (Paco2 less than 40 mmHg; 1 mmHg = 133.3 Pa), group 2 (Paco2 between 40(More)
Summary The distinction between soma and germline is an important process in the development of animals with sexual reproduction. It is regulated by a number of germline-specific genes, most of which appear conserved in evolution and therefore can be used to study the formation of the germline in diverged animal groups. Here we report the isolation of two(More)
The incidence of Type 1 (insulin-dependent) diabetes mellitus was prospectively evaluated in Catalonia, Spain in patients up to 30 years of age during the period 1987–1990. The population at risk (0–29 years) consisted of 2,690,394 inhabitants (total population of Catalonia 5,978,638). All the cases were independently identified from four sources:(More)
Cnidarians are primitive animals located in a basal position in the phylogenetic tree of the Animal Kingdom, as an outgroup of the Bilaterians. Therefore, studies on cnidarian developmental biology may illustrate how fundamental developmental processes have originated and changed during animal evolution. A particular example of this is the establishment of(More)
OBJECTIVE We sought to determine whether patients with stable chronic obstructive pulmonary disease (COPD) whose exercise performance is mainly limited by dyspnoea are able to improve their exercise tolerance after rehabilitation with an individualized programme based on aerobic training at the ventilatory threshold (VT) level. PATIENTS AND EXPERIMENTAL(More)
An effective treatment of advanced states of chronic obstructive pulmonary disease (COPD) has yet to be established. We report the case of a COPD patient with severe hypoxemia (pO2 = 32.0 mm Hg) and hypercapnia (pCO2 = 90.0 mm Hg) who was successfully treated for 8 months with nasal intermittent positive-pressure ventilation (NIPPV) plus supplemental O2 in(More)
