DNA methylation dynamics associated with long-term isolation of simulated space travel

open access: yesiScience, 2022
Long-term isolation is one of the risk factors that astronauts will encounter in spaceflight. At present, few researches have explored DNA methylation dynamics during long-term isolation.

Optimization of DNA extraction from human urinary samples for mycobiome community profiling. [PDF]

open access: yes, 2019
IntroductionRecent data suggest the urinary tract hosts a microbial community of varying composition, even in the absence of infection. Culture-independent methodologies, such as next-generation sequencing of conserved ribosomal DNA sequences, provide an

Restriction Fragment Length Polymorphism Linkage Map for Arabidopsis thaliana [PDF]

open access: yes, 1988
We have constructed a restriction fragment length polymorphism linkage map for the nuclear genome of the flowering plant Arabidopsis thaliana. The map, containing 90 randomly distributed molecular markers, is physically very dense; >50% of the genome is ...

Isolation by distance in a population of a small land snail Trochoidea geyeri : evidence from direct and indirect methods [PDF]

open access: yes, 2006
Population structure was estimated in a continuous population of a small land snail (Trochoidea geyeri). Mark-recapture experiments and randomly amplified polymorphic DNA analyses indicate that the population structure can be described by the isolation ...

Comparative analysis of human DNA extraction methods and mitochondrial DNA HV1 and HV2 haplogroup determination [PDF]

open access: yesKragujevac Journal of Science, 2020
The high integrity of extracted DNA is necessary for the determination of human haplogroups, based on the mitochondrial DNA (mtDNA) marker sequences. The study aims were to isolate the total DNA from selected human samples and establish a protocol that ...

Improved Screening of cDNAs Generated by mRNA Differential Display Enables the Selection of True Positives and the Isolation of Weakly Expressed Messages [PDF]

open access: yes, 1997
The high percentage of false positives generated by differential display (as high as 85%) has previously limited the potential of the method. This report describes an efficient methodology that enables false positives to be discarded prior to cloning ...
