Standard mammograms from 33 patients with surgically proved adenocarcinoma or fibrocystic disease were analyzed with a scanning microdensitometer and computer. A quickly computable number called the linear mass ratio is introduced. This simple ratio discriminated correctly between the 16 adenocarcinomas and 17 fibrocystic lesions of the study, all cases in which diagnosis had required biopsy.
The objective of this research is two-fold: (i) the development of a method for locating hemorrhages, blood clots, and tumors in the brain by means of ordinary hospital radiographs and without the introduction of contrast material; and (ii) the uncovering of new mathematical results through this point of view. The present note deals mainly with the first objective, but the mathematical setting and convergence and indeterminacy theorems are also described.

Organophosphate and carbamate insecticides are the most common forms of pesticide poisoning. They present with a distinctive clinical syndrome that is, nevertheless, sometimes difficult to recognize. Early treatment is important, and specific antidotal therapy is available using atropine and pralidoxime. Important complications that need to be monitored during therapy may involve the central and peripheral nervous system, lungs, and heart.
