STUDIES OF T H E CHLORIDE TRANSPORT I N T H E GASTRIC MUCOSA OF T H E FROG* BY ERICH HEINZ xm~ RICHARD P. DURBIN

The unidirectional fluxes of CIand Na + across the frog gastric mucosa in vitro were investigated with radioactive isotopes, and related to the secretory and electrical properties of the normal, and metabolically inhibited, mucosa. The flux of C1from nutrient to secretory surface of the mucosa was observed to rise sharply with increasing acid secretion, while the corresponding flux of Na + did ...

HUGE ANEURYSM OF T H E DUCTUS ARTERIOSUS IN CHILDHOOD: CASE REPORT AND LITERATURE REVIEW

Patent ductus arteriosus (PDA) is an open communication between the upper descending thoracic aorta and the proximal left pulmonary artery, which results from persistence of the fetal ductus arteriosus. It may be isolated or occur with other congenital cardiac anomalies. Aneurysms of the ductus arteriosus are rare lesions which may occur as a spontaneous. infantile fonn or occur in later c...

On a Problem in T H E Theory of Groups Arising in T H E Foundations of Infinitesimal Geometry* by H. P. Robertson and H. Weyl

In the book which accompanies the stencils various methods of finding quadratic residues are discussed and the method by means of the expansion of the square root of the number in a continued fraction is found to be by far the most effective. Various examples are given illustrating the power of the stencils, and a reproduction of the first page of the list of primes accompanies the work. The pl...
