Expression of MAGE-A12 in Oral Squamous Cell Carcinoma

Melanoma associated-A antigens (MAGE-A) are silent in normal tissues except testis. However, they are activated ina variety of different tumors. Thus, their expression is highly specific to cancer cells. Reverse transcription-nested polymerase chain reaction (RT-nPCR) is a highly sensitive technique that has been used successfully for the detection of MAGE genes in tissue samples. The aim of th...

Gibberellin Metabolism in Maize (The Stepwise Conversion of Gibberellin A12-Aldehyde to Gibberellin A20.

The stepwise metabolism of gibberellin A12-aldehyde (GA12-aldehyde) to GA20 is demonstrated from seedling shoots of maize (Zea mays L.). The labeled substrates [13C,3H]GA12-aldehyde, [13C,3H]GA12, [14C4]GA53, [14C4/2H2]GA44, and [14C4/2H2]GA19 were fed individually to dwarf-5 vegetative shoots. Both [13C,3H]GA12-aldehyde and [13C,3H]GA12 were also added individually to normal shoots. The labele...

Amino acids and peptides. XVI. Synthesis of a tetrapeptide sequence (A9-A12) of glucagon.

A synthesis of the tetrapeptide sequence As-Ag of glucagon is described that employs various blocking groups, coupling procedures, and routes. The threonyl-phenylalanyl-threonyl-seryl sequence A5-A8 in the hyperglycemic hormone, glucagon (Foa and Galansino, 1962), has been prepared by three different groups within the past four years (Beyerman and Bontekoe, 1964; Schroder and Gibian, 1962; Wuns...

Assignment Asci Course A12 Neural Computing Systems: Car Racing with Reinforcement Learning

1 Reinforcement learning using temporal diierences. Suppose one wants to play a game of chess, and develop a strategy of doing this in an optimal way. Only after playing it is clear whether the moves that were made were advantageous or not. Also, one only ends up with a \common" yes/no-decision, hence a separate credit assignment to all individual moves is a nontrivial task. This example can be...
