Generating stable conditions for membrane proteins after extraction from their lipid bilayer environment is essential for subsequent characterization. Detergents are the most widely used means to obtain this stable environment; however, different types of membrane proteins have been found to require detergents with varying properties for optimal extraction(More)
Canavan disease is a fatal neurological disease without any effective treatments to slow the relentless progress of this disorder. Enzyme replacement therapy has been used effectively to treat a number of metabolic disorders, but the presence of the blood-brain-barrier presents an additional challenge in the treatment of neurological disorders. Studies have(More)
The first structure of an NAD-dependent tartrate dehydrogenase (TDH) has been solved to 2 A resolution by single anomalous diffraction (SAD) phasing as a complex with the intermediate analog oxalate, Mg(2+) and NADH. This TDH structure from Pseudomonas putida has a similar overall fold and domain organization to other structurally characterized members of(More)
Canavan disease (CD) is a fatal neurological disorder caused by defects in the gene that encodes for a critical metabolic enzyme. The enzyme aspartoacylase catalyzes the deacetylation of N-acetylaspartate to produce acetate required for fatty acid biosynthesis in the brain. The loss of aspartoacylase activity leads to the demyelination and disrupted brain(More)
The present research work involved the reaction of 2,3-dihydro-1,4-benzodioxin-6-amine (1) and benzenesulfonyl chloride (2) under dynamic pH control at 10 using aqueous Na2CO3. This reaction yielded 2,3-dihydro-1,4-benzodioxin-6-yl)benzenesulfonamide (3), which was further substituted at N-position with various alkyl/aryl halides (4a – 4m) in(More)
The aim of the research was to investigate the anti-bacterial potential of some N-substituted sulfonamides bearing benzodioxane moiety. The synthesis was started by reaction of N-2,3-dihydrobenzo[1,4]dioxin-6-amine with 4-acetamidobenzene-1-sulfonyl chloride in the presence of 10% aqueous Na2CO3 solution to yield(More)
The author hereby grants to MIT permission to reproduce and to distribute publicly paper and electronic copies of this thesis document in whole or in part in any medium now known or hereafter created. ABSTRACT Scheduling for production in manufacturing environments requires an immense amount of planning. A large number of factors such as part availability,(More)
Polymorphism within the promoter region of bovine thyroglobulin has been reported to be associated with milk and meat quality. In this study, we investigated the genetic variation within thyroglobulin promoter region of swamp and riverine buffaloes using PCR-SSCP technique and sequencing, and also analyzing association of polymorphism with the milk(More)
Canavan disease is a fatal neurological disorder caused by the malfunctioning of a single metabolic enzyme, aspartoacylase, that catalyzes the deacetylation of N-acetyl-L-aspartate to produce L-aspartate and acetate. The structure of human brain aspartoacylase has been determined in complex with a stable tetrahedral intermediate analogue,(More)
BACKGROUND Management of aplastic anemia is etiology driven, whether constitutional or acquired. Age, gender, and severity of disease also play crucial role in the survival of aplastic anemia. Since, inadequate data are available from India, the present study was conducted with the aim to evaluate the etiology and survival of aplastic anemia. METHODS(More)
