TIERE is perhaps no literature dealing with specific disease addressed to the patient so voluminous as that on the subject of diabetes. This can probably be explained by the fact that there is no other disease in which the physician has to rely, to the same extent, upon self-treatment by the patient. Yet in spite of the plethora of books, this small volume, written by a certified dietitian, wil...

The International Labor Organization (ILO) system for classifying chest radiographic changes related to inhalation of pathogenic dusts is predicated on film-screen radiography (FSR). Digital radiography (DR) has replaced FSR in many centers, but there are few data to indicate whether DR is equivalent to FSR in identifying and quantifying interstitial and pleural abnormalities. Furthermore, DR i...

The multitrait-multimethod matrix approach as proposed by Campbell and Fiske (1959) was an important contribution to our understanding of the nature of validation procedures. There are, however, problems encountered when using the Campbell and Fiske (1959) approach. The purpose of this article is to discuss the method and selected problems, and to propose an alternate approach to address those ...

(Campbell, 1965), earthworms (Bishop and Campbell, 1963, 1965) and snails (Campbell and Bishop, 1970; Campbell and Speeg, 1968; Tramell and Campbell, 1972) via the ornithine–urea cycle (OUC) indicates that the usurpation of the basic nutritional pathway of arginine synthesis for ammonia detoxification first took place in invertebrate animals (Campbell, 1973). Osmotic water retention may have be...

The superior colliculus (SC) receives a retinotopic projection of the contralateral visual field in which the representation of the central field is expanded with respect to the peripheral field. The visual projection forms a nonlinear, approximately logarithmic, map on the SC. Models of the SC commonly assume that the function defining the strength of neuronal connections within this map (the ...

Abnormal forms of prion protein (PrP(Sc)) accumulate via structural conversion of normal PrP (PrP(C)) in the progression of transmissible spongiform encephalopathy. Under cell-free conditions, the process can be efficiently replicated using in vitro PrP(Sc) amplification methods, including protein misfolding cyclic amplification. These methods enable ultrasensitive detection of PrP(Sc); however...
