Non-Adjunctive Inference and Classical Modalities

Molecular chaperones: Small heat shock proteins in the limelight

Small heat shock proteins have been the Cinderellas of the molecular chaperone world, but now the crystal structure of a small heat shock protein has been solved and mutation of two human homologues implicated in genetic disease. Intermediate filaments appear to be one of the key targets of their chaperone activity.

Idiopathic segmental infarction of the greater omentum.

Segmental infarction of the omentum is a rare disease, with about 150 published cases, and an unusual cause of "pseudoacute" abdomen. The preoperative diagnosis is difficult because of the rarity and lack of specificity of the syndrome, and it is established after laparotomy, with a few exceptions. The authors report on a personal case and emphasize the importance of systematic exploration in s...
