This paper describes a novel methodology where Machine Learning Algorithms (MLAs) have been integrated to assess the landslide risk for slow moving mass movements, processes whose intermittent activity makes challenging any analysis worldwide. MLAs has trained on datasets including Interferometric Synthetic Aperture Radar (InSAR) and additional remote sensing such as aerial stereo photographs L...

In order to investigate the chemically or physically produced double strand DNA scissions, we have tried to detect 3•L-termini of the lesions. The termini were detected by an enzymic assay using 3H-TTP and terminal deoxynucleotidyl transferase, followed by rapid scintillation autoradiography. This enzyme is generally used for adding complementary homopolymer to vector and cDNA in recombinant DN...

The interaction of amino pyrrolopyrimidine nucleotides with enzymes catalyzing different steps in the reaction sequence leading to the incorporation of amino acids into polypeptides has been studied. None of the analogue nucleotides could function as the energy source for activation of amino acids or esterification of transfer RNA (tRNA) by mammalian or bacterial enzymes. Toyocamycin S’-triphos...

The role of Dicer's helicase domain is enigmatic, but in vivo it is required for processing certain endogenous siRNA, but not miRNA. By using Caenorhabditis elegans extracts or purified Drosophila Dicer-2 we compared activities of wild-type enzymes and those containing mutations in the helicase domain. We found the helicase domain was essential for cleaving dsRNA with blunt or 5'-overhanging te...

The gene PRT1 of Arabidopsis, encoding a 45-kD protein with two RING finger domains, is essential for the degradation of F-dihydrofolate reductase, a model substrate of the N-end rule pathway of protein degradation. We have determined the function of PRT1 by expression in yeast (Saccharomyces cerevisiae). PRT1 can act as a ubiquitin protein ligase in the heterologous host. The identified substr...

Voltage-dependent ion channels are thought to consist of a highly conserved repeated core of six transmembrane segments, flanked by more variable cytoplasmic domains. Significant functional differences exist among related types of K+ channels. These differences have been attributed to the variable domains, most prominently the N- and C-termini. We have therefore investigated the functional impo...

Defective interfering RNAs have long been thought to be a causal factor of persistent RNA virus infections. Here we describe a novel type of defective genome of lymphocytic choriomeningitis virus and the unique mechanism by which these RNAs appear to contribute to the establishment and maintenance of persistent infection. The defective genomes have short deletions in the untranslated regions at...

A number of nuclear encoded inner membrane proteins of mitochondria span the membrane in such a manner that their N termini are located in the intermembrane space. Many of these proteins attain this membrane orientation by undergoing an export step from the matrix across the inner membrane. This export process, which resembles bacterial N-tail export from energetic and topogenic signal requirem...

The mitochondrial DNA (mtDNA) control regions for common chimpanzee, pygmy chimpanzee and gorilla were sequenced and the lengths and termini of their D-loop DNA's characterized. In these and all other species for which there are data, 5' termini map to sequences that contain the trinucleotide YAY. 3' termini are 25-51 nucleotides downstream from a sequence that is moderately conserved among ver...

Centrioles are small barrel-shaped structures that form centrosomes and cilia [1]. Centrioles assemble around a central cartwheel comprising the Sas-6 and Ana2/STIL proteins. The amino termini of nine Sas-6 dimers form a central hub of ∼12 nm radius from which nine dimer spokes radiate, placing the Sas-6 carboxyl termini at the outer edge of the ∼60 nm radius cartwheel [2]. Several centriole pr...
