The relative retrotransposition efficiencies of human and mouse short interspersed DNA elements (SINEs) in a HeLa cell culture assay
<p>Short interspersed DNA elements (SINEs) and long interspersed DNA elements (LINEs) represent two families of transposable elements (TEs) within mammalian genomes. About 45% of the human genome consists of TE derived sequences. SINEs do not encode protein, so they cannot be autonomously …

Práticas para a cidadania ativa e ambientalmente consciente : um estudo sobre prevenção, redução, reutilização, separação e reciclagem de resíduos em Sines
… Básica Nº 2 (EB2) do Agrupamento de Escolas de Sines. O trabalho delineou-se pela perceção da problemática - resíduos urbanos – que fez questionar sobre o que podemos fazer para que os resíduos sejam, cada vez mais, reduzidos, reutilizados, reciclados e devidamente encaminhados e valorizados? No …

Diversity and Evolution of Short Interspersed Nuclear Elements (SINEs) in Angiosperm and Gymnosperm Species and their Application as molecular Markers for Genotyping
Short interspersed nuclear elements (SINEs) are small non-autonomous and heterogeneous retrotransposons, widespread in animals and plants and usually differentially propagated in related species resulting in genome-specific copy numbers. Within the monocots, the Poaceae (sweet grasses) is the …

Regulation of mammalian SINE transcription
… of the templates, both human and rodent SINEs are normally expressed at a very low level. DNA methylation-mediated silencing has been proposed as a possible cause of their transcriptional repression. The effect of DNA methylation and the effect of DNA methylation-dependent …

Dissecting the role of CHD4 in the NuRD and ChAHP complexes
… that extend beyond the known role of ChAHP at B2 SINEs. ADNP and CHD4 are found at repetitive elements of various classes as well as at regulatory regions, including promoters and active enhancers. Using the dTAG depletion system for ADNP and the auxin depletion system for CHD4 followed by …

Mammalian-wide interspersed repeats (MIRs) and their role in mammalian gene function and evolution
… (MIRs) are short interspersed nuclear elements (SINEs), belonging to the non-autonomous class of retroelements and are found in all mammals. The recruitment of an MIR element by a gene may provide insight into mammalian evolution and gene function.

Expression levels of non-autonomous retrotransposons in germ-line rodent tissues
<p>SINEs (short interspersed DNA elements) are families of non-coding regions of DNA that amplify within genomes via an RNA intermediate and are referred to as retrotransposons. These elements mobilize using machinery from other retrotransposons and therefore are non-autonomous. It has been …

An analysis of human Alu element lineages
… distinct groups of Short INterspersed Elements (SINEs) found exclusively in primates. These lineages are comprised of several distinct subfamilies, which contain elements that are evolutionarily-related because they share common diagnostic mutations. Some of these Alu subfamilies are still …

Efficient arithmetic for high speed DSP implementation on FPGAs
… CORDIC systems computing vector magnitudes and cosines/sines is presented. This work allows the most efficient CORDIC design for a specified level of accuracy to be found quickly and easily without the need to run lengthy simulations, as was the case before. The CORDIC algorithm is a technique …

Axial Cyclic Response of Unnotched and Notched Carburized Cylindrical Members Under Constant Amplitude Completely Reversed Loading
… Multiaxial fatigue approaches proposed by Sines and Manson are utilized for the prediction of notched member life using the unnotched fatigue data. Unconservative estimates of life are achieved and these methods do not seem promising. However, good correlation is found using the …
