A number of patients with inflammatory arthritis due to inadequate clinical or laboratory data do not fulfill diagnostic criteria for a clinical disease categories. These patients with initial diagnosis of undifferentiated arthritis (UA) may remit or progress to a definite well- defined condition such as rheumatoid arthritis (RA) or remain as UA with persistence of inflammatory arthritis. The m...

In this issue of Clinical Cancer Research , Desai et al. (1) present evidence that new modules appearing in preexisting lesions can represent clonally resistant populations. Imatinib mesylate, the prototypic oral tyrosine kinase inhibitor that has activity against ABL, KIT, and platelet-derived growth factor receptor kinases arguably represents the most important oncologic advance of the past 3...

multiple sclerosis (ms) is a demyelinating disease of the central nervous system, with unknown etiology in which both genetic and environmental factors are thought to be involved. the human leukocyte antigen (hla) system provides a set of genetic markers which lend themselves to systematic study. in iran, hla-a24, hla-dr2, and hla- dr15 are significantly increased in ms patients. the disease al...

CONTEXT Structural brain abnormalities have consistently been found in schizophrenia, with increased familial risk for the disease associated with these abnormalities. Some brain volume changes are progressive over the course of the illness. Whether these progressive brain volume changes are mediated by genetic or disease-related factors is unknown. OBJECTIVE To investigate whether genetic an...

Two groups have studied the loss of limbs in snake evolution by focusing on a long-distance cis-acting enhancer of Sonic Hedgehog. They find a progressive degeneration of binding sites for key transcription factors, mirroring the progressive limblessness occurring in these reptiles.
