PURPOSE Alterations in collagen type IV, alpha-3 (COL4A3) and collagen type IV, alpha-4 (COL4A4) genes may be responsible for a decrease in collagen types I and III, a feature often detected in keratoconus (KC). To evaluate the significance of alterations in COL4A3 and COL4A4 genes in KC patients, we screened both genes and estimated the significance of polymorphisms in Slovenian patients with ...
Remote sensing-based crop monitoring has evolved unprecedentedly to supply multispectral imagery with high spatial-temporal resolution for the assessment of evapotranspiration (ETc). Several methodologies have shown a correlation between Vegetation Indices (VIs) and coefficient (Kc). This work analyzes estimation (Kc) as spectral function product two variables: VIs green vegetation cover fracti...
The pharmacokinetics and tissue distribution of the monoclonal antibody radioconjugate 111In-diethylenetriaminepentaacetic acid-KC-4G3, which is directed against a high molecular weight mucin(s) antigen expressed on the human milk fat globule and many epithelial cell membranes, were examined in BALB/c nude mice with and without xenografts of the human tumor lines ZR-75 (mammary adenocarcinoma, ...
We have studied intracellular catabolism of heparan sulfate proteoglycans (HSPGs) in Drosophila cell lines, Kc and S2, by a series of pulse-chase experiments using [(35)S]sulfate as a precursor in metabolic labeling experiments. HSPGs in culture medium and cell layer were separately purified by serial chromatographic procedures using Q-Sepharose and Superose 6 for characterization. Analysis of ...
The melanogenic system of the liver pigmented macrophages of Rana esculenta L.--tyrosinase activity.
The enzyme system responsible for Amphibian Kupffer Cell (KC) melanogenesis has not been entirely elucidated. This research demonstrates that the KC melanosomes of Rana esculenta L. possess a tyrosine-hydroxylase (TH) activity, showing that a tyrosinase is the enzyme involved in the melanogenesis. The TH reaction depends on catalytic Dopa as a cofactor and is not affected by catalase or H2O2, s...
OBJECTIVE Oxysterols such as 7-ketocholesterol (7-KC) are important mediators of cell death in atherosclerosis. Therefore, in vitro studies of human smooth muscle cell (SMC) death in response to 7-KC were undertaken to investigate the potential mechanisms. METHODS AND RESULTS Human aortic SMCs treated with 7-KC showed enhanced immunoreactivity for the oxidative stress marker 4-hydroxy-2-nonen...
BACKGROUND The Atlantic Wood Industries Superfund site on the Elizabeth River (ER) in Portsmouth, Virginia, is contaminated with polycyclic aromatic hydrocarbons (PAHs) derived from creosote. Embryos and larvae of ER killifish (Fundulus heteroclitus) are refractory to the induction of enzymes regulated by the aryl hydrocarbon receptor including cytochrome P4501A (CYP1A) and are resistant to PAH...
Molecular cloning studies have revealed the existence of a large family of voltage-gated K+ channel genes expressed in mammalian brain. This molecular diversity underlies the vast repertoire of neuronal K+ channels that regulate action potential conduction and neurotransmitter release and that are essential to the control of neuronal excitability. However, the specific contribution of individua...
One of the reasons complex analytic dynamics has been such a successful subject is the deep relation that has surfaced between conformal mapping, dynamics and combinatorics. The object of the spider algorithm is to construct polynomials with assigned combinatorics. This shows up when you try to understand the Mandelbrot set. For this discussion we will write our quadratic polynomials Qc(z) = z ...
