Genetic analysis in Drosophila reveals a role for the mitochondrial protein p32 in synaptic transmission Mitochondria located within neuronal presynaptic terminals have been shown to play important roles in the release of chemical neurotransmitters. In the present study, a genetic screen for synaptic transmission mutants of Drosophila has identified the first mutation in a Drosophila homolog of the mitochondrial protein P Although P32 is highly conserved and has been studied extensively, its physiological role in mitochondria remains unknown and it has not previously been implicated in neural function. The Drosophila P32 mutant, referred to as dp32EC1, exhibited a temperature-sensitive TS paralytic behavioral phenotype. Moreover, electrophysiological analysis at adult neuromuscular synapses revealed a TS reduction in the amplitude of excitatory postsynaptic currents EPSC and indicated that dP32 functions in neurotransmitter release. These studies are the first to address P32 function in Drosophila and expand the knowledge of mitochondrial proteins contributing to synaptic transmission Lutas, A genetic screen for synaptic transmission mutants in Drosophila isolated a new mutation in a Drosophila homolog of the mitochondrial protein P32, which represents the first P32 mutation in a multicellular organism. Although P32 is highly conserved and has been studied extensively, its physiological function in mitochondria remains unknown. This new mutant, referred to as dP32EC1, exhibited a temperature-sensitive TS paralytic behavioral phenotype. Moreover, electrophysiological analysis at adult neuromuscular synapses revealed a TS reduction in neurotransmitter release, indicating that dP32 serves an important function in synaptic transmission. which of the following can disrupt genetic equilibriumCard No. It may be used as the method of cleanup or in concept with other site cleanup concepts. The fundamental concept for in situ stabilization is chemical treatment of the waste within the soil medium.

The use of a treatment agent reactanta means for delivering the reactant to the waste and usually a means for recovering the products of the reactions. As with other Superfund site remediation technology, the application of these systems to uncontrolled waste sites will require a site-by-site, customized approach that considers the uniqueness of the combina- tion of the subsurface geohydrology, waste inventory and site history at each site. There is also extensive need for complementary laboratory simulations and testing prior to implementation of this concept. The report is intended to present information on the potential application of a number of in situ treatment technologies for the stabilization of deposits containing various organic waste compounds.
It is not intended to address every conceivable waste type or all possible applications of the technologies described.
Mention of trade names or commercial products does not fo endorsement or recommendation for use. During or following treatment, spent reactants or stabilization by-products may require removal from the waste deposit and the surrounding soil. This section provides information currently available concerning the various aspects of delivery and recovery systems usable for in situ stabilization.
Sections provide information currently available on the biological and chemical processes and reagents that may be applicable to waste deposit stabilization. Section 6 integrates all of the foregoing, to establish guidance concerning the use of stabilization technologies at specific sites.
The specific objectives of Section 1 are to: 1. Identify and review the various soils engineering parameters affecting equiilibrium selection and application of delivery and recovery systems Section 1. Review the types and features of various gravity and forced delivery systems Section 1. Review the types and features of various gravity and forced recovery systems Section 1.
Review delivery and recovery enhancement technology available through electro-osmosis Section 1. Present a comparative analysis of alternative delivery and recovery systems Section 1. In theory, there are numerous possible combinations of settings and geohydrology which could arise. Based on an understanding of the geohydrology of the site it may be determined that it is necessary to completely contain the waste deposit and any leachate generated, or place a hydrologic barrier downgradient of the deposit to assist the recovery system. Grout curtains, slurry walls, and sheet pilings have been used for this purpose. A description of these methods is beyond the scope of this work, but is contained in companion documents to this report, including A. Martin AssociatesA. Gravity delivery can also be applied, however, in cases crime rational the subsurface deposit is overlain by an impermeable cover if the impermeable layer can be cost-effectively removed, or subsurface methods of gravity delivery e.
However, shallow injection well points can be used for some shallow waste deposits. Forced recovery is generally required for deeper deposits or less permeable conditions.]
