Nucleic acid detection aboard the International Space Station by colorimetric loop‐mediated isothermal amplification (LAMP)

open access: yesFASEB bioAdvances, 2020
Human spaceflight endeavors present an opportunity to expand our presence beyond Earth. To this end, it is crucial to understand and diagnose effects of long‐term space travel on the human body.

Consistent ultra-long DNA sequencing with automated slow pipetting

open access: yesBMC Genomics, 2021
Background Oxford Nanopore Technologies’ instruments can sequence reads of great length. Long reads improve sequence assemblies by unambiguously spanning repetitive elements of the genome.

Repetitive DNA loci and their modulation by the non-canonical nucleic acid structures R-loops and G-quadruplexes

open access: yesThe Nucleus, 2017
Cells have evolved intricate mechanisms to maintain genome stability despite allowing mutational changes to drive evolutionary adaptation. Repetitive DNA sequences, which represent the bulk of most genomes, are a major threat to genome stability often ...

STR technique for the detection of contamination by exogenous DNA in paraffin blocks and histological slides

open access: yesSurgical and Experimental Pathology, 2019
Gastrointestinal Stromal Tumors (GIST) present different types of mutations that may or may not be sensitive to specific target therapy. The laboratory procedure required to prepare histological sections traditionally demands multiple steps, making the ...

Rapid capture of DNA targets

open access: yesBioTechniques, 2008
A rapid capture technique was developed to efficiently isolate specific DNA targets from a variety of genomes. The specificity can be easily adapted to any target for which partial sequence is known, allowing for the isolation of a wide set of target ...

The challenge of small-scale repeats for indel discovery

open access: yesFrontiers in Bioengineering and Biotechnology, 2015
Repetitive sequences are abundant in the human genome. Different classes of repetitive DNA sequences, including simple repeats, tandem repeats, segmental duplications, interspersed repeats and other elements, collectively span more than 50% of the genome.

Systematic identification of stem-loop containing sequence families in bacterial genomes

open access: yesBMC Genomics, 2008
Background Analysis of non-coding sequences in several bacterial genomes brought to the identification of families of repeated sequences, able to fold as secondary structures.

Semipermeable Cellulose Beads Allow Selective and Continuous Release of Small Extracellular Vesicles (sEV) From Encapsulated Cells

open access: yesFrontiers in Pharmacology, 2020
The clinical benefit of therapies using Mesenchymal Stem Cells (MSCs) is attributable to their pleiotropic effect over cells and tissues, mainly through their secretome.
