Mathematical methods and models for radiation carcinogenesis studies

Research on radiation carcinogenesis requires a twofold approach. Studies of primary molecular lesions and subsequent cytogenetic changes are essential, but they cannot at present provide numerical estimates of the risk of small doses of ionizing radiations. Such estimates require extrapolations from dose, time, and age dependences of tumor rates observed in animal studies and epidemiological investigations, and they necessitate the use of statistical methods that correct for competing risks. A ...

The variance of a poisson process of domains

A familiar relation links the densities that result for the intersection of a convex body and straight lines under uniform isotropic randomness with those that result under weighted randomness. An extension of this relation to the intersection of more general domains is utilized to obtain the variance of the n-dimensional measure of the intersection of two bodies under uniform isotropic randomness. The formula for the variance contains the point-pair distance distributions for the two domains — ...

Surgical concepts for reconstruction of the auricle

We compiled and evaluated the world literature on auricular reconstruction, for a total of over 400 publications, more than 200 authors, and over 3,300 reported cases. We found that partial reconstructions were already performed as early as 600 BC; total reconstructions were still considered impracticable in 1830. But since 1891, more than 40 different cartilaginous, osseous, and alloplastic frame materials have been described. Only eight of these were still being applied in the last decade, wit...

Value of Ascitic Lipids in the Differentiation between Cirrhotic and Malignant Ascites

Ascitic fluid concentrations of cholesterol, triglycerides and phospholipids, were compared with ascitic fluid total protein in 40 patients with chronic liver disease, 51patients with various neoplasms and 1 patient with cardiac failure. Seven patients withboth chronic liver disease and malignancy were considered separately. The first 54 patients (23 cirrhotic and 31 with malignancy) were used to determine median values and ranges and to define the most suitable cutoff concentrations between bot...

Evidence for down-regulation of beta-2-adreno-ceptors in cirrhotic patients with severe ascites

The density and affinity of beta-2-adrenoceptors on mononuclear cells from peripheral blood were studied in fifteen patients with cirrhosis of different severity and in thirteen controls. There was no significant difference between cirrhotic patients and controls in density or affinity of beta-2 binding sites. Within the cirrhotic group, however, the number of binding sites per cell was significantly lower in patients with severe ascites than in patients with mild to moderate or no ascites. This...

Changes in extracellular pH during electrical stimulation of isolated rat vagus nerve

Double-barrelled pH-sensitive micro-electrodes were used to record changes of extracellular pH during repetitive stimulation of isolated rat vagus nerves. It was found that a small initial alkaline shift was followed by a prolonged acidification. The acidification was correlated in time with the poststimulus undershoot of the extracellular K+ activity and with the recovery phase of the nerve conduction velocity. In the presence of ouabain, the acid component of the pH change was completely aboli...

Excitatory amino acids and intracellular pH in motoneurons of the isolated frog spinal cord

Double-barrelled pH-sensitive micro-electrodes were used to measure changes of intracellular and extracellular pH in and around motoneurons of the isolated frog spinal cord during application of excitatory amino acids. It was found that N-methyl- -aspartate, quisqualate and kainate produced a concentration-dependent intracellular acidification. Extracellularly, triphasic pH changes (acid-alkaline-acid going pH transients) were observed during the action of these amino acids. The possible signifi...

Chronic Paroxysmal Hemicrania: The First Possible Bilateral Case

There are three headaches syndromes that are typically characterized by strictly unilateral and always same-sided attacks: cluster headache, “cervicogenic” headache, and chronic paroxysmal hemicrania (CPH). In rare cases, cluster headache also occurs bilaterally; “cervicogenic” headaches probably as well. We present a patient with a probable bilateral CPH. To our knowledge no such case has previously been described.
