A receptor-containing, steroid-resistant clone of CEM cells, CEM-C1, was isolated without selective pressure from the wildtype population. The biological and physicochemical properties of glucocorticoid receptors in CEM-C1 cells were compared to those from a clone (CEM-C7) sensitive to glucocorticoid-mediated lysis. In a whole-cell binding assay, CEM-C1 cells exhibited high affinity for [3H]dex...

Leaf maturation from initiation to senescence is a phenological event of plants that results from the influences of temperature and water availability on physiological activities during a life cycle. Detection of newly grown leaves (NGL) is therefore useful for the diagnosis of tree growth, tree stress, and even climatic change. This paper applies Constrained Energy Minimization (CEM), which is...

Correspondence: Cem Yasar Sanhal e-mail: cemsanhal@ yahoo.com Objective. To compare the efficacy of five adhesions barrier products with a control group in a rat model. Methods. In this randomized controlled animal study, standardized lesions on parietal peritoneum of rats were created by sandpaper and three interrupted sutures. Afterwards, the lesions were treated with Seprafilm, Interceed, Pr...

Solithromycin (CEM-101) is a new antibiotic that is highly potent against Ureaplasma and Mycoplasma spp. and active against many other antibiotic-resistant organisms. We have explored the maternal-amniotic-fetal pharmacokinetics of CEM-101 in a pregnant sheep model to assess its potential for treating intrauterine and antenatal infection. Chronically catheterized pregnant ewes (n = 6 or 7) rece...

Recent improvements to the Cascade-Exciton Model (CEM) of nuclear reactions are briefly described. They concern mainly the cascade stage of reactions and a better description of nuclei during the preequilibrium and evaporation stages of reactions. The development of the CEM concerning fission is given in a separate talk at this conference. The increased accuracy and predictive power of the CEM ...

The use of self-adhesive resin cements is accomplished by a simple clinical step, in which the simultaneous demineralization/infiltration of the bonding substrate takes place. However, the self-adhesive resin cements have lower bond strength than conventional resin cements that rely on the application of etch-and-rinse adhesive systems. In order to increase the bond strength of the self-adhesiv...

We report here new characteristics of cell surface tubulin from a human leukemia cell line. These cells (CEM cells) possess tubulin that is readily iodinated on the surface of living cells, turns over at a rate identical to that of other surface proteins, and is present throughout the cell cycle. When removed with trypsin, it rapidly returns to the surface. Peptide mapping of iodinated surface ...

In this study, the release of gentamicin as a function of time was measured for six different gentamicin-loaded bone cements and related with the surface roughness, porosity and wettability of the cements. Initial release rates varied little between the six bone cements (CMW1, CMW3, CMW Endurance, CMW 2000, Palacos, and Palamed) and ranged from 8.6 to 14.1 microg/cm2/h. The total amounts of gen...

Surface parameterizations have been widely applied to digital geometry processing. In this paper, we propose an efficient conformal energy minimization (CEM) algorithm for computing conformal parameterizations of simply-connected open surfaces with a very small angular distortion and a highly improved computational efficiency. In addition, we generalize the proposed CEM algorithm to computing c...

The development of dental materials with improved properties and increased longevity can save costs and minimize discomfort for patients. Due to their good biocompatibility, glass ionomer cements are an interesting restorative option. However, these cements have limited mechanical strength to survive in the challenging oral environment. Therefore, a better understanding of the structure and hyd...
