To investigate the patterns of DNA ploidy and proliferating activity in breast cancer and relate them to other prognostic factors, paraffin blocks of 53 cases of breast carcinoma were studied. Cancer cells obtained by mechanical tissue disaggregation were examined for DNA content, ploidy and S-phase fraction. DNA assay was done using a CAS interactive image analyzing system. All of the cas...

In this paper, the author present a reliable symbolic computational algorithm for inverting a general comrade matrix by using parallel computing along with recursion. The computational cost of our algorithm is O(n). The algorithm is implementable to the Computer Algebra System (CAS) such as MAPLE, MATLAB and MATHEMATICA. Three examples are presented for the sake of illustration.

While most dicot plants produce little ethylene in their vegetative stage, many monocots such as rice liberate a relatively large amount of ethylene with cyanide as a co-product in their seedling stage when etiolated. One of the known functions of beta-cyanoalanine synthase (CAS) is to detoxify the co-product cyanide during ethylene biosynthesis in higher plants. Based on a tryptic peptide sequ...

Este artigo investiga as estruturas dos conselhos de administração (CAs) das empresas listadas no Brasil e sua relação com desempenho financeiro. Para isso, construiu-se uma base dados sobre características da propriedade do capital CAs a partir extraídos relatórios anuais que essas submeteram à Comissão Valores Mobiliários (CVM) entre 2003 2013. Os resultados obtidos não fornecem evidências o ...

Approximately all sequenced archaeal and half of eubacterial genomes have some sort of adaptive immune system, which enables them to target and cleave invading foreign genetic elements by an RNAi-like pathway. CRISPR–Cas (clustered regularly interspaced short palindromic repeats–CRISPR-associated proteins) systems consist of the CRISPR loci with multiple copies of a short repeat sequence separa...

Syndrome de la queue de cheval. A propos de 4 cas.  Les auteurs rapportent quatre observations cliniques concernat des malades dont les pre­miers symptomes se manifesterent par des al­gies longitemps considerees comme "sciatique·s".  L' etude neurologique de ces cas demontrait qu'en realite "les algies sciatiques" n'etaient que des signes mono ou pluri-radiculaires en rapport avec un syndrome...

Enterobacter aerogenes representa uma bactéria gram negativa anaeróbia facultativa, não formadora de esporos. Apresenta-se como um microrganismo multirresistente que está diretamente relacionado a infecções oportunistas, sobretudo em ambiente hospitalar. Essa dispõe diversos mecanismos para se mantenha ativa, podemos destacar dentre estes, utilização do sistema CRISPR-Cas imunizá-las da infecçã...

the objective of this research is to identify the characteristics of cost accounting systems (cas) in manufacturing companies located in the state of fars. the research is designed to answer the following questions: 1- what kind of management information systems (mis) are in - use. 2-what information are provided by these systems. 3-how - offen financial information. are issues. 4- what groups ...

Shiga toxin-producing Escherichia coli (STEC) comprise a group of zoonotic enteric pathogens with ruminants, especially cattle, as the main reservoir. O-antigens are instrumental for host colonization and bacterial niche adaptation. They are highly immunogenic and, therefore, targeted by the adaptive immune system. The O-antigen is one of the most diverse bacterial cell constituents and variati...

Background : Ruptured cerebral aneurysms (ICAs) are the most common non-traumatic cause of subarachnoid hemorrhage (SAH) that is associated with life threatening complications such as Vasospasm, Infarction, and Hydrocephalus (HCP). The active participation of macrophage/monocyte-mediated inflammatory response in the pathogenesis of cerebral aneurysm as labeled with Monocyte ChemoattractantProte...
