Extracellular miR-6723-5p could serve as a biomarker of limbal epithelial stem/progenitor cell population

Biomarker Research, 2022
Background Dysfunction or loss of limbal stem cells can result in limbal stem cell deficiency (LSCD), a disease that cause corneal opacity, pain, and loss of vision.

Video block and FABEMD features for an effective and fast method of reporting near-duplicate and mirroring videos

Journal of Big Data, 2021
Near-duplicate video content has taken the large storage space in the age of big data. Without respecting the copyright ethic, social media users mirror, resize, and/or hide certain online video content and re-upload it as new data. This research aims to

The presence of radioactive heavy minerals in prospecting trenches and concomitant occupational exposure.

PLoS ONE, 2021
Uranium, perhaps the most strategically important component of heavy minerals, finds particular significance in the nuclear industry. In prospecting trenches, the radioactivity of 238U and 232Th provides a good signature of the presence of heavy minerals.

Methods and algorithms for extracting high-content signatures from cells, tissues, and model organisms

2011 IEEE International Symposium on Biomedical Imaging: From Nano to Macro, 2011
While high-content screening is already playing an important role in drug discovery, a growing number of academic laboratories are applying these techniques to conduct a system-level analysis of biological processes. In this context more complex assays and model systems are being imaged at higher throughput. Examples include co-culture assays, tissues,

Compositional and functional difference in cumin (Cuminum cyminum) essential oil extracted by hydrodistillation and SCFE

Cogent Food & Agriculture, 2016
Essential oils were obtained from same raw material of cumin seed by extraction with hydrodistillation and super critical fluid extraction (SCFE). For SCFE, supercritical carbon dioxide at 45°C and 100 bar was used as variable for the extraction.

Assessment of simple sequence repeats signature in hepatitis E virus (HEV) genomes

Journal of Genetic Engineering and Biotechnology, 2022
Background Hepatitis E virus (HEV) is small (27–34 nm diameter) non-enveloped with positive sense ssRNA genome. Microsatellites or simple sequence repeats (SSR) are short tandem repeat sequences present across coding and non-coding regions of both ...
