NASA launched the Earth Observing System's flagship satellite "Terra," named for Earth, on December 18, 1999. Terra has been collecting data about Earth's changing climate Normalized Difference Vegetation Index (NDVI) is a simple graphical indicator that can be used to analyze remote sensing measurements. These indexes can be used to prediction of classes of Remote Sensing (RS) images. In this ...
Telomere dysfunction is closely associated with human diseases such as cancer and ageing. Inappropriate changes in telomere length and/or structure result in telomere dysfunction. Telomeres have been considered to be transcriptionally silent, but it was recently demonstrated that mammalian telomeres are transcribed into telomeric repeat-containing RNA (TERRA). TERRA, a long non-coding RNA, part...
Article history: Received 15 July 2009 Received in revised form 8 February 2010 Accepted 9 April 2010 The latestMODIS aerosol optical depth (AOD) retrieval algorithm (C005) based on analyses of global AERONET data for both Terra and Aqua satellites has gradually supplanted the older algorithm (C004) since 2006. However, due to few AERONET sites in China, assessing applications of MODIS products...
This paper presents TERRA and ACQUA 1 two mechanisms that support adaptable definition and execution of workflows. TERRA generates and stores structures (objects, events, reactions) necessary for executing a workflow. AQUA executes workflows according to a parametric behaviour model that represents workflow execution policies in terms of dimensions associated to values. TERRA and ACQUA provide ...
Article history: Received 2 July 2016 Received in revised form 4 December 2016 Accepted 29 December 2016 Available online 25 January 2017 Accurately monitoring global vegetation dynamics with modern remote sensing is critical for understanding the functions and processes of the biosphere and its interactions with the planetary climate. The MODerate resolution Imaging Spectroradiometer (MODIS) v...
Maintenance of telomeres, repetitive elements at eukaryotic chromosomal termini, and the end-capping structure and function they provide, are imperative for preserving genome integrity and stability. The discovery that telomeres are transcribed into telomere repeat containing RNA (TERRA) has revolutionized our view of this repetitive, rather unappreciated region of the genome. We have previousl...
مقدمه: پرهاکلامپسی نوعی سندرم اختصاصی حاملگی است که تمام اعضای بدن را تحت تأثیر قرار میدهد. یکی از علل احتمالی پرهاکلامپسی، عوامل ژنتیکی از جمله ژنهای زمینهساز ارثی میباشد. مطالعه حاضر با هدف مقایسه سطح بیان LncRNA TERRA و طول تلومر در نمونه جفت زنان مبتلا به پرهاکلامپسی و سالم انجام شد. روشکار: در این مطالعه مورد- شاهدی که در سال 97-1396 انجام شد، از 25 زن مبتلا به پرهاکلامپسی ک...
Telomeres, the physical ends of eukaryotic chromosomes, consist of tandem arrays of short DNA repeats and a large set of specialized proteins. A recent analysis has identified telomeric repeat-containing RNA (TERRA), a large noncoding RNA in animals and fungi, which forms an integral component of telomeric heterochromatin. TERRA transcription occurs at most or all chromosome ends and it is regu...
Telomere erosion causes cell mortality, suggesting that longer telomeres enable more cell divisions. In telomerase-positive human cancer cells, however, telomeres are often kept shorter than those of surrounding normal tissues. Recently, we showed that cancer cell telomere elongation represses innate immune genes and promotes their differentiation in vivo. This implies that short telomeres cont...
The conserved PAF1 complex (Cdc73, Paf1, Ctr9, Leo1 and Rtf1, in yeast), binds RNA pol II, and affects levels of many RNAs. Although PAF1 is a complex, there is evidence that different components perform different functions. In yeast, Cdc73, Paf1 and Ctr9 maintain normal telomerase RNA (TLC1) levels and affect telomere length. Here we report a new connection between the PAF1 complex and telomer...
