    Aloft: A Language Oriented to Flight Engineering & Testing

    Get PDF
    A high order computer language called ALOFT has been developed for the checkout and operation of complex space oriented equipment such as the proposed NASA Space Shuttle. The flexibility of the language makes it equally suited for use with existing launch vehicles such as Saturn, Titan, etc. and space systems such as Space Station, Viking, etc. With such flexibility it can be assumed that the language will be equally acceptable to future vehicles, space experiments, etc. Flexibility is obtained by making the language independent of any test system and providing for the user to define a wide variety of words and functions, This later capability also makes it independent of the device it is testing. The paper describes the language and its syntax. It also shows its ability to operate in a multidiscipline environment independent of the test system

    Glutathione Restores the Mechanism of Synaptic Plasticity in Aged Mice to That of the Adult

    Glutathione (GSH), the major endogenous antioxidant produced by cells, can modulate the activity of N-methyl-D-aspartate receptors (NMDARs) through its reducing functions. During aging, an increase in oxidative stress leads to decreased levels of GSH in the brain. Concurrently, aging is characterized by calcium dysregulation, thought to underlie impairments in hippocampal NMDAR-dependent long-term potentiation (LTP), a form of synaptic plasticity thought to represent a cellular model for memory
