    The E-cadherin cell-cell adhesion pathway in urologic malignancies (1995)
    Springer
    World journal of urology 13 (1995), S. 364-368 
    Details
    ISSN: 1433-8726
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary Alterations in the E-cadherin-mediated cell-cell adhesion pathway are commonly observed in urologic malignancies. This issue has been addressed most thoroughly in prostate cancer. Whereas both cadherin and catenin dysfunction have been seen in human prostate cancers, only down-regulation of E-cadherin has been shown for bladder cancer and renal-cell carcinoma. Although studies in bladder cancer and renal-cell carcinoma are less mature than studies in prostate cancer, they support the hypothesis that immunostaining for E-cadherin may be of significance for both diagnostic and prognostic purposes. Finally, the E-cadherin-mediated cell-cell adhesion pathway may represent a novel chemotherapeutic target for bladder cancer, prostate cancer, and renal-cell carcinoma. Obviously, more work lies ahead to translate these important observations from the bench to the bedside.

    Variation in tibial torsion (1994)
    New York, NY [u.a.] : Wiley-Blackwell
    Clinical Anatomy 7 (1994), S. 76-79 
    Details
    ISSN: 0897-3806

    Notes: A skeletal collection from the African country of Sudan was examined to determine if torsion of the tibia in an African population varies from established norms for European, Asian, and American populations. A large variation in tibial torsion was observed. There was a distinct limb asymmetry with more torsion on the right than left. No association of tibial torsion with gender was identified. A small but appreciable increase in average torsion (7°) was identified when this population was compared with previously reported populations. This study documents a variation in tibial torsion not appreciated in earlier studies. © 1994 Wiley-Liss, Inc.

    Variation in femoral anteversion (1994)
    New York, NY [u.a.] : Wiley-Blackwell
    Clinical Anatomy 7 (1994), S. 72-75 
    Details
    ISSN: 0897-3806

    Topics: Medicine
    Notes: Variation in femoral anteversion in an adult African skeletal population is examined in this study. Variation is measured in reference to population, gender, and side of the extremity (right vs. left). This study demonstrates greater average anteversion (19°) and a significant right-left variation (21 vs. 17) when compared to previously reported Caucasian and Oriental populations. The increased anteversion complements previous reports documenting morphologic differences between populations in length and width of the femur. This study documents a variation in femoral anteversion not appreciated in earlier studies that may be clinically useful in the assessment and correction of “abnormal” anteversion. © 1994 Wiley-Liss, Inc.

    Melt viscosity increase during rheological testing of poly(phenylene sulfide) (1993)
    New York, NY [u.a.] : Wiley-Blackwell
    Journal of Applied Polymer Science 50 (1993), S. 1903-1907

    Notes: Poly(phenylene sulfide) (PPS) made via the melt polymerization of p-diiodobenzene and sulfur has previously been reported to increase in melt viscosity with time during rheological testing. Analysis of the oligomer from cleavage of PPS chains at the disulfide bonds via solution in 1-chloronaphthalene demonstrated that the disulfide content of the polymer decreased with rheological testing time. DSC of the polymer before and after rheological testing in combination with the Tcc and Tm of the chain fragments after the dissolution/cleavage in 1-chloronaphthalene showed that many samples exhibited primarily chain extension rather than chain branching, whereas for many others, some degree of chain branching occurred. This is currently only qualitatively understood. Chain branching as the exclusive mechanism of melt viscosity increase during rheological testing appears untenable in light of the Tm, in particular, of the chain fragments and also the polymer prior to chain cleavage. © 1993 John Wiley & Sons, Inc.
