Epidermal growth factor (EGF) is excreted in urine in high concentrations and thus incubates with bladder epithelial cells continuously. However, it is not known whether any urothelial cells can bind urinary EGF or respond to it. Using a monoclonal antibody (528) to the binding portion of the human EGF receptor, immunoperoxidase staining demonstrated that(More)
ABSTRACT Begomoviruses (the family Geminiviridae) are transmitted by the whitefly Bemisia tabaci and contain monopartite or bipartite circular single-stranded (ss)DNA genomes. They have emerged as severe problems in the production of agricultural and horticultural crops worldwide. Here, we report the identification of a tomato breeding line, FLA653, that(More)
Gastric absorption of feruloylquinic acid and di-O-caffeoylquinic acid analogs has never been investigated despite their potential contribution to the proposed beneficial health effects leading to reduced risk of type 2 diabetes. Using a cultured gastric epithelial model, with an acidic apical pH, the relative permeability coefficients (P(app)) and(More)
To assess the effect of polyamine blockade on urinary epithelium, growth of normal human urothelial cell cultures and human transitional cell carcinoma (TCC) cell lines in the presence of various inhibitors of polyamine synthesis was evaluated. All four human TCC cell lines tested were quite sensitive to the specific inhibitor of ornithine decarboxylase,(More)
Wild relatives of the cultivated tomato (Solanum lycopersicum L.) are major sources of new genetic diversity for tomato improvement. Introgression lines (IL) are near-isogenic lines homozygous for one or several mapped wild DNA fragments in a common recurrent parent. A set of ILs developed by Cornell University from Solanum habrochaites accession LA1777 and(More)
The various physiological effects of alpha-MSH, mainly on the CNS and on pigmentation in animal models, are well documented in the literature. Only a few investigators have confirmed similar properties in the human. However, the possible physiopathological role played by this hormone in human melanoma is still poorly defined. In order to approach this(More)
A decision tree to assist in the process of selecting an appropriate algorithm for the numerical solution of initial value ordinary differential equations is described. This initial value tree contains a series of questions that are intended to identify specific features of a user’s problem, relevant to the selection of suitable software. An appropriate(More)
Synthetic alpha-melanocyte-stimulating hormone (alpha-MSH) was found to bind to the plasma membrane of the HM6A human melanoma cell line, using an immunocytochemical method. When treated with 10(-7) to 10(-9) M alpha-MSH, melanoma cells exhibited an increase of intracellular cyclic adenosine 3':5'-monophosphate, followed by stimulation of tyrosinase(More)
Food security requires that all people can access sufficient food for a healthy life. Enough food is produced to feed the global population, but more than 1.02 billion people are malnourished. Malnutrition and chronic food insecurity are widespread in some countries of the Asia-Pacific region; as much as 20 to 60 percent of the region's population lacks(More)
