We show that a simple procedure based on maximizing the number of informative content-words can produce some of the best reported results for multi-document summarization. We first assign a score to each term in the document cluster, using only frequency and position information, and then we find the set of sentences in the document cluster that maximizes the sum of these scores, subject to len...
A kindred segregating for Van der Woude syndrome (VWS) through five generations is described. Biochemical and serological phenotypes at 36 polymorphic marker loci have been determined, of which 27 were informative for linkage analysis to the VWS gene (LIPED 3 computer programme). Lod scores are reported and show exclusion of close linkage for most of the marker loci. Only VWS:Duffy (Fy) resulte...
Phylogeny and genetic diversity of Amphioctopus fangsiao were assessed by sequence analysis of complete mitochondrial genomes, sequenced from 15 individuals of nine populations. The whole mtDNA genomes size were ranging from 15977 to 15990 bp. Data revealed 1642 polymorphic sites and 1023 parsimony informative sites. The phylogenetic analysis based on neighbor joining tree disclosed two clades...
Grapevine (Vitis vinifera L.) is a clonally propagated major fruit crop. In grapevine, identification of genotypes with amplographical features is often based on mature plant characteristics that may be affected by environmental conditions. This approach lacks objectivity and reliability. Recently, molecular markers have proved to be supplementary techniques to analyze genetic diversity and exa...
The intermediate hosts of Schistosoma mansoni, in Brazil, Biomphalaria glabrata, B. tenagophila and B. straminea, were identified by restriction fragment length polymorphism analysis of the mitochondrial gene cytochrome oxidase I (COI). We performed digestions with two enzymes (AluI and RsaI), previously selected, based on sequences available in Genbank. The profiles obtained with RsaI showed t...
Modern co-revolution is presented as an important component of the historical transition from era objectification to humanization, industrial post-industrial and epoch-making humanizing revolution; dialectical unity latest knowledge-information-digital revolutions in context global evolutionary-revolutionary processes. The past mechanical, modern electronic-digital future post-electronic stages...
Genetic diversity of 12 lemon balm ecotypes was evaluated using agronomic traits as well as ISSR and RAPD markers. Results of analysis of variance showed high diversity among the studied ecotypes. Cluster analysis using UPGMA method grouped the ecotypes into three different groups based on the agronomic traits. Twelve ISSR primers created 106 polymorphic bands among the studied ecotypes. An ISS...
Loss of heterozygosity occurring on various chromosomes has been described in the majority of human tumors. The targets of frequent or consistent subchromosomal deletions are believed to be tumor suppressor genes. We examined 72 esophageal tumors (46 squamous cell carcinomas and 26 adenocarcinomas) for loss of heterozygosity at the p53, Rb, APC, MCC, and DCC loci. Inclusion of these tumor suppr...
