Dual‐mode biosensing platform for ultrasensitive Salmonella detection based on cascaded signal amplification coupled with DNA‐functionalized Ag2S NPs@PB

open access: yesFood Frontiers, 2023
Salmonella is one of the most common zoonotic foodborne pathogens and can cause serious threats to public health and global economy. A dual‐mode biosensing platform was demonstrated based on cascaded signal amplification coupled with DNA‐functionalized ...

Assessing the Epigenetic Status of Human Telomeres [PDF]

open access: yes, 2019
The epigenetic modifications of human telomeres play a relevant role in telomere functions and cell proliferation. Therefore, their study is becoming an issue of major interest.

The Echinococcus canadensis (G7) genome: A key knowledge of parasitic platyhelminth human diseases [PDF]

open access: yes, 2017
Background: The parasite Echinococcus canadensis (G7) (phylum Platyhelminthes, class Cestoda) is one of the causative agents of echinococcosis. Echinococcosis is a worldwide chronic zoonosis affecting humans as well as domestic and wild mammals, which ...

Observation and Quantification of Telomere and Repetitive Sequences Using Fluorescence In Situ Hybridization (FISH) with PNA Probes in Caenorhabditis elegans.

open access: yesJournal of Visualized Experiments, 2016
Telomere is a ribonucleoprotein structure that protects chromosomal ends from aberrant fusion and degradation. Telomere length is maintained by telomerase or an alternative pathway, known as alternative lengthening of telomeres (ALT)(1).

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 ...

Genomic Selective Constraints in Murid Noncoding DNA [PDF]

open access: yes, 2006
Recent work has suggested that there are many more selectively constrained, functional noncoding than coding sites in mammalian genomes. However, little is known about how selective constraint varies amongst different classes of noncoding DNA.

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.

Small Open Reading Frames, Non-Coding RNAs and Repetitive Elements in Bradyrhizobium japonicum USDA 110 [PDF]

open access: yes, 2016
Small open reading frames (sORFs) and genes for non-coding RNAs are poorly investigated components of most genomes. Our analysis of 1391 ORFs recently annotated in the soybean symbiont Bradyrhizobium japonicum USDA 110 revealed that 78% of them contain ...

The evolutionary dynamics of variant antigen genes in Babesia reveal a history of genomic innovation underlying host-parasite interaction [PDF]

open access: yes, 2014
Babesia spp. are tick-borne, intraerythrocytic hemoparasites that use antigenic variation to resist host immunity, through sequential modification of the parasite-derived variant erythrocyte surface antigen (VESA) expressed on the infected red blood cell

Breakthrough Solution for Antimicrobial Resistance Detection: Surface‐Enhanced Raman Spectroscopy‐based on Artificial Intelligence

open access: yesAdvanced Materials Interfaces, EarlyView., 2023
This review discusses the use of Surface‐Enhanced Raman Spectroscopy (SERS) combined with Artificial Intelligence (AI) for detecting antimicrobial resistance (AMR). Various SERS studies used with AI techniques, including machine learning and deep learning, are analyzed for their advantages and limitations.
