    Comparison of differentiation patterns in 12-O-tetradecanoylphorbol-13-acetate-treated epidermis and fetal epidermis (1985)

    Notes: Summary 12-O-Tetradecanoylphorbol-13-acetate (TPA)-treated adult epidermis as well as untreated fetal and adult epidermis were investigated to elucidate the effect of TPA in terms of cell differentiation using techniques of ultrastructural stereology. Twenty-four hours after a single application of TPA, the treated epidermis was characterized by involutional changes, i. e., increased volume density of intercellular spaces and of mitochondria, vacuoles, and cytoplasmic ground substance in the basal layer. However, 48 h after application, the TPA-treated epidermis was very similar to fetal epidermis, i. e., high volume density of nuclei ribosomes, rough endoplasmic reticulum, membrane-coating granules, and keratohyalin granules, and low volume density of bundled filaments in the upper layers. These stereological data indicate that the changes observed 48 h after TPA treatment were related not only to increased cell proliferation but also to inhibition of cell differentiation expressed as a reversion of the adult differentiation patterns and the acquisition of fetal characteristics in all epidermal layers.

    Contribution of immunophenotypic and genotypic analyses to the diagnosis of acute leukemia (1995)

    Notes: Abstract Diagnostic accuracy in acute leukemia (AL) can be improved if traditional morphology and cytochemistry are supplemented with immunophenotypic and genotypic analyses. This multiparameter approach is of crucial importance for the management of patients, as it enables the identification of leukemic syndromes with distinct biological features and response to treatment. Immunophenotyping using monoclonal antibodies has been universally accepted as a useful adjunct to morphological criteria. This technique is particularly valuable in diagnosing and subclassifying acute lymphoblastic leukemia and is also essential in certain types of acute myeloid leukemia (AML), such as AML with minimal differentiation or acute megakaryoblastic leukemia. Cytogenetic findings can be quite helpful in establishing the correct diagnosis and can add information of prognostic significance. A number of specific chromosomal abnormalities have been recognized that are very closely, and sometimes uniquely, associated with morphologically and clinically distinct subsets of leukemia. An even more basic understanding of normal and malignant hematopoietic cells has begun to evolve as molecular biology begins to unravel gene misprogramming by Southern and Northern blot analysis, the polymerase chain reaction, and fluorescence in situ hybridization. With the extensive use of these techniques it has become apparent that a proportion of leukemias exhibit the biologically relevant molecular defect in the absence of a karyotypic equivalent. On the other hand, apparently uniform chromosomal abnormalities such as the t(1;19) (q23;p13), t(9;22) (q33;q11), t(8;14) (q24;q32), or t(15;17) (q21;q21) may differ at the molecular level. Data collected from these modern technologies have introduced a greater complexity, which needs to be taken into consideration to improve both the diagnostic precision and the reproducibility of current classifications.

    Estimating transit time for capillary blood in selected muscles of exercising animals (1992)
    Springer
    Pflügers Archiv 421 (1992), S. 578-584

    ISSN: 1432-2013

    Topics: Medicine
    Notes: Abstract The mean minimal capillary transit time was estimated in muscles of various animals using a combination of physiological and morphometric methods. Radioactive microspheres were injected intravascularly in various animals running on a treadmill at maximum oxygen consumption rate (VO2,max) to label blood flow to individual muscles. The muscles were then removed and preserved by standard methods for electron microscopy. The volume density of mitochondria was measured to assess muscle oxidative capacity. Capillary densities in muscle cross-sections, capillary diameters and tortuosities were incorporated into an estimate of capillary volume per unit muscle mass. Mean capillary transit time (t c) in the exercising muscles was estimated by dividing mass-specific capillary volume by mass-specific blood flow. Estimates of t c ranged from values near 1 s in horse heart and thigh muscles to 0.2 s in duck gastrocnemius. The relationship between muscle blood flow and t c was hyperbolic. The experimental data indicate a limiting value of 0.2 s for transit times at very high blood flows. There was no correlation between t c and body-mass-specific VO2,max.

    On the construction and numerical solution of transmission-line and lumped network models of Maxwell's equations (1980)
    Chichester [u.a.] : Wiley-Blackwell
    International Journal for Numerical Methods in Engineering 15 (1980), S. 13-30

    Notes: It is sometimes convenient to express a numerical algorithm in terms of a network model. The physical picture given can often help the engineer to visualize the properties of the method. In field problems, a lumped network model corresponds to a space discrete field while a transmission-line model corresponds to a field which is discrete in space and time. In this paper, the relationship is given between the lumped network models and transmission-line network models used in the steady-state solution of Maxwell's equations in two and three space dimensions. The use of dual networks is also discussed. An analysis is given for the velocity of waves travelling in any direction across the networks and this is used to compare the accuracy of the models. The use of diakoptics or substructures for the solution of large networks is outlined and this is illustrated by a compound two-dimensional example.

    Notes: Heat transfer associated with forced convection between bundles of cylindrical fuel rods is analysed using the finite element method. A subchannel technique is employed and the numerical results are compared with previous experimental and numerical values. The solid and fluid zones are analysed, for temperature distribution, as a single domain.
