INTRODUCTION To provide clinical information and diagnosis in mouth breathers with transverse maxillary deficiency with posterior crossbite, numerous exams can be performed; however, the correlation among these exams remains unclear. OBJECTIVE To evaluate the correlation between acoustic rhinometry, computed rhinomanometry, and cone-beam computed tomography in mouth breathers with transverse ...

Overview This is a very preliminary proposal on encoding the Pollard script in Unicode and ISO/IEC 10646. The targeted location for encoding would be Plane 1, as Pollard is a recently invented script with limited current use. Any suggestions on improvement would be greatly appreciated.

The CC chemokine eotaxin plays a pivotal role in local accumulation of eosinophils. Very little is known about the eotaxin signaling in eosinophils except the activation of the mitogen-activated protein (MAP) kinase family. The p21 G protein Rho and its substrate Rho-associated coiled-coil forming protein kinase (ROCK) regulate the formation of stress fibers and focal adhesions. In the present ...

U937 cells lacking mitochondrial DNA (rho [symbol: see text] cells) are auxotrophic for uridine and pyruvate, hypersensitive to hypoglycemic conditions, and resistant to antimycin A-induced apoptosis. In spite of their obvious metabolic defects, rho [symbol: see text] cells possess a normal mitochondrial transmembrane potential, as well as near-normal capacity to generate superoxide anion after...

Endothelium of fetal or newborn arteries is atypical, displaying actin stress fibers and reduced nitric oxide (NO)-mediated dilatation. This study tested the hypothesis that Rho/Rho kinase signaling, which promotes endothelial stress fibers and inhibits endothelial dilatation, contributed to this phenotype. Carotid arteries were isolated from newborn [postnatal day 1 (P1)], P7, and P21 mice. En...

The stem cell pool can be fractionated by using the mitochondrial dye, rhodamine-123, into Rho(low) hematopoietic stem cells and Rho(high) progenitors. Rho(low) stem cells permanently engraft all lineages, whereas Rho(high) progenitors transiently produce erythrocytes, without substantial platelet or granulocyte production. We hypothesized that the inability of the Rho(high) cells to produce pl...

Although peroxisome proliferator-activated receptor (PPAR ) ligands have an antihypertensive effect in vivo, the precise mechanism has not been fully elucidated. We examined their effects on Rho/Rho kinase pathway, a key regulator of vascular tone. In cultured rat aortic smooth muscle cells (RASMC), Rho kinase stimulated by angiotensin II was suppressed by the pretreatment with pioglitazone and...

Rho factor has been purified from a strain of E. coli containing the Su78 mutation in the suA gene and assayed in another strain with an amber mutation in the suA gene. The rho from the Su78 mutant strain is present in normal amounts but has altered termination function; it does not terminate transcription at some sites that are recognized effectively by the rho factor from the isogenic wild-ty...

A novel regulatory protein for the rho proteins (rhoA p2 1 and rhoB p20), belonging to a ras p2 llras p21like small molecular weight (M,) GTP-binding protein (G protein) superfamily, was purified to near homogeneity from bovine brain cytosol and characterized. This regulatory protein, designated here as GDP dissociation inhibitor (GDI) for the rho proteins (rho GDI), inhibited the dissociation ...
