Lifetime Alcohol Use Influences the Association Between Future-Oriented Thought and White Matter Microstructure in Adolescents.

Aims: Future orientation, or the ability to plan ahead and anticipate consequences, is a capacity that develops during adolescence, yet its underlying neurobiology is unknown. Previous independent reports suggest that reduced future orientation and altered white matter microstructure are associated with greater alcohol use in adolescents; however, these effects have not been studied in conjunction. This study investigated the association between future orientation and white matter microstructure as a function of lifetime alcohol use.

SRF selectively controls tip cell invasive behavior in angiogenesis.

Efficient angiogenic sprouting is essential for embryonic, postnatal and tumor development. Serum response factor (SRF) is known to be important for embryonic vascular development. Here, we studied the effect of inducible endothelial-specific deletion of Srf in postnatal and adult mice.

A screen for mutations in zebrafish that affect myelin gene expression in Schwann cells and oligodendrocytes.

Myelin is the multi-layered glial sheath around axons in the vertebrate nervous system. Myelinating glia develop and function in intimate association with neurons and neuron-glial interactions control much of the life history of these cells. However, many of the factors that regulate key aspects of myelin development and maintenance remain unknown.

[Changes in the acid-base status of the synovial fluid in rheumatoid arthritis patients].

Aim: The study of changes in joint fluid (JF) acid-base balance in RA patients to evaluate severity of joint lesions, efficacy of on-going therapy and to predict appearance and persistence of RA remission.

Materials And Methods: A routine examination and measurements of JF pH of the affected joints and venous blood before and during the treatment were performed in 65 RA patients with articular or articular-visceral forms (46 and 19 patients, respectively). 19 patients were seropositive and 20 seronegative by rheumatoid factor.

Studies in developmental cytomechanic.

One of the most promising trends in modern developmental and cell biology, recently defined as <>, or <>, is directed towards revealing the role of mechanical stresses, chemomechanical transduction and active stress responses of cells antissues of developing embryos. We review here the results obtained in this field by our research group and compare them with those from other labs. Our studies relate to the buds of hydroid polypes and to amphibian embryos.
