Versatile vector tools for efficient protein screening across multiple expression systems

open access: yesFEBS Open Bio, EarlyView.
A unified vector toolkit enables rapid protein expression screening across E. coli, insect, and mammalian cells. A single primer pair amplifies the target gene, which is inserted into any vector via a standardized interface. This streamlined workflow eliminates repeated cloning steps, accelerating the identification of optimal expression conditions for

Is telomere length a biomarker for aging: cross-sectional evidence from the west of Scotland? [PDF]

open access: yes, 2012
Background <p> The search for biomarkers of aging (BoAs) has been largely unsuccessful to-date and there is widespread skepticism about the prospects of finding any that satisfy the criteria developed by the American Federation of Aging Research ...

Equivalent linearization technique in non-linear stochastic dynamics of a cable-mass system with time-varying length

open access: yesArchives of Mechanics, 2019
In this paper the transverse vibrations of a vertical cable carrying a concentrated mass at its lower end and moving slowly vertically within the host structure are considered.

Small RNA pathways in mammalian oocytes

open access: yesFEBS Open Bio, EarlyView.
Three distinct small RNA pathways operate in mammalian oocytes: RNAi interference (RNAi), the microRNA (miRNA) pathway, and the PIWI‐associated RNA (piRNA) pathway. These pathways use small RNAs to guide sequence‐specific repression and contribute to oocyte biology by targeting genes and mobile elements or appear insignificant since different ...

Stretching rates and equivalent length near the tropopause [PDF]

open access: yesJournal of Geophysical Research: Atmospheres, 2003
Diagnostics of mixing in the upper troposphere/lower stratosphere region reveal interesting seasonal and interannual variability and illustrate how the subtropical tropopause can be identified with a region of minimum mixing, a partial barrier to the transport of air between the troposphere and stratosphere.

Transcripts enriched in codons that trigger P‐site tRNA‐mediated mRNA decay possess stable mRNA

open access: yesFEBS Open Bio, EarlyView.
PTMD codons were first described by Mendel et al. as mediators of an mRNA decay pathway dependent on the human protein CNOT3, homologous to yeast Not5. Our findings confirm that PTMD codons destabilize transcripts; however, unlike in yeast, the human pathway specifically targets and slightly destabilizes primarily stable mRNAs.

Effects of length-thickness ratio on the dynamic calculation accuracy of the honeycomb panel equivalent models

open access: yes, 2019
In order to improve the numerical calculation accuracy of the hexagonal aluminum honeycomb panel, the influence of the length-thickness ratio on the dynamic calculation accuracy of the equivalent models is studied. The modal frequencies of the equivalent

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

A black-box dynamic equivalent model for microgrids using measurement data [PDF]

open access: yes, 2014
A dynamic equivalent black-box model, based on Prony analysis is presented. The proposed model is suitable for dynamic studies of microgrids, considering changes in the active and reactive powers, bus voltages, currents and frequency. The developed model
