Abstract

In order to evaluate physiological traits related to biochemical basis of drought tolerance under moisture stress, a field experiment with ten sorghum genotypes was carried out in split plot design with three replications. Seeds were grown separately under three moisture regimes viz; moisture stress condition with irrigation applied at the time of sowing, terminal stress condition with irrigation applied at the time of sowing and panicle initiation stage and non stress condition with irrigation applied at various critical growth stages. The accumulation of proline and glycine betaine was higher under moisture stress than terminal stress and non-stress condition. Accumulation of proline and glycine betaine content was recorded at the time of 50% flowering and at dough stage to estimate the efficiency of drought tolerance. Among the genotypes under study, RSV 1237 accumulated more leaf proline, whereas, RSV 1572 accumulated more glycine betaine at 50% flowering stage and dough stage under moisture stress. Genotypes differed significantly with respect to leaf, stem, panicle and total dry matter per plant. RSV 1237 and RSV 1572 had better partitioning of dry matter into reproductive parts under moisture and terminal stress conditions. It was concluded that these genotypes could be useful in sorghum breeding for drought tolerance. [ABSTRACT FROM AUTHOR]

Abstract

A series of Ti based shape memory alloys with composition of Ti50Ni48Fe2, Ti50Ni47Fe3 and Ti50Ni45Fe5 were developed by vacuum arc melting under a purified argon atmosphere. The study was designed to evaluate in vivo cytotoxicity of the Ti-Ni-Fe shape memory alloy system. The materials were implanted in rabbits, and blood examination and histology of various vital organs (liver, heart and kidney) were performed to determine cytotoxicity of these alloy systems, if any, after 4, 8 and 12 weeks. The results showed that Ti-Ni-Fe alloy neither was cytotoxic nor has any systemic reaction on living system in any of the test performed. Implantation shows good compatibility and a potential of being used directly in in vivo system. [ABSTRACT FROM AUTHOR]

Abstract

Udgivelsesdato: 1992-null, The phenotype in the rd mouse is similar to the clinical presentation of Leber congenital amaurosis (LCA) in humans. Recently a nonsense mutation in the beta subunit of the cGMP phosphodiesterase (Pdeb) gene has been defined as the cause for the rd phenotype in the mouse and has raised the question as to whether mutations in the human PDEB gene might cause LCA. We have previously cloned and characterized the human homologue of the mouse Pdeb gene and have mapped it to chromosome 4p16.3. In this study, a total of 23 LCA families of various ethnic backgrounds have been investigated. Linkage analysis using highly polymorphic (CA)n microsatellites has excluded the PDEB gene as a cause for LCA in 6 families. In the remaining 17 families, we have searched for mutations in the 22 exons of the PDEB gene using single-strand gel electrophoresis (SSGE). Multiple exonic polymorphisms have been determined. However, no DNA changes in the PDEB gene have been identified in our study population which could be causative for the LCA phenotype.
