Liver fibrosis protects mice from acute hepatocellular injury.

Background & Aims: Development of fibrosis is part of the pathophysiologic process of chronic liver disease. Although it is considered deleterious, it also represents a form of tissue repair. Deposition of extracellular matrix changes the cellular environment of the liver; we investigated whether it increases resistance to noxious stimuli and the role of changes in intracellular signaling to hepatocytes in mediating this effect.

Index variation from field-assisted ion exchange.

Concentration distributions produced from the combined effect of a unidirectional electric field and diffusion are presented for a slab and for a hollow cylinder. A field in the direction such that slow ions follow fast ones results in a stationary distribution that moves with a constant or nearly constant velocity. If the field is in the opposite direction, it tends to mix the ions, and an entirely different distribution that never reaches a steady state is obtained.

Echinococcosis in Egypt: IV. Serology on patients with chest problems.

Patients complaining of chest disorders were clinically and serologically examined for evidence of echinococcal infection. Serologically, the patients were screened by the indirect haemagglutination test and reactors were confirmed by the bentonite flocculation and/or latex-agglutination tests. Of 755 patients 6.
