Nuclear transfer technique affects mRNA abundance, developmental competence and cell fate of the reconstituted sheep oocytes [PDF]

Reproduction, 2013
Abstract The effect of technical steps of somatic cell nuclear transfer (SCNT) on different aspects of cloned embryo development was investigated in sheep. In vitro-matured oocytes were enucleated in the presence or absence of zona and reconstituted by three different SCNT techniques: conventional zona-intact (ZI-NT), standard zona ...

A Review of the Uses of Nuclear Radiation in Tobacco and Smoke Research

Contributions to Tobacco and Nicotine Research, 1990
In summary, nuclear radiation has been widely used to elucidate many aspects of the mechanisms of tobacco being converted to smoke. In addition, the mechanisms of smoke transfer, tobacco inorganic chemistry and smoke filtration have been clarified by ...

Nuclear reprogramming: kinetics of cell cycle and metabolic progression as determinants of success

, 2012
Establishment of totipotency after somatic cell nuclear transfer (NT) requires not only reprogramming of gene expression, but also conversion of the cell cycle from quiescence to the precisely timed sequence of embryonic cleavage.

Synthesis, characterization and evaluation of transfection efficiency of dexamethasone conjugated poly(propyleneimine) nanocarriers for gene delivery#

Pharmaceutical Biology, 2018
Context: Polypropylenimine (PPI), a cationic dendrimer with defined structure and positive surface charge, is a potent non-viral vector. Dexamethasone (Dexa) conveys to the nucleus through interaction with its intracellular receptor.

Mitochondrial transfer: Ethical legal and social implications in assisted reproduction

South African Journal of Bioethics and Law, 2015
Diseases resulting from mutations in mitochondrial DNA (mtDNA) are inherited by all offspring through the maternal lineage. Multiple organs, which require high cellular energy production, are severely affected.

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Quantitative CEST imaging of amide proton transfer in acute ischaemic stroke

NeuroImage: Clinical, 2019
Background: Amide proton transfer (APT) imaging may help identify the ischaemic penumbra in stroke patients, the classical definition of which is a region of tissue around the ischaemic core that is hypoperfused and metabolically stressed.

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...

The Influence of Neighbouring Clouds on the Clear Sky Reflectance Studied with the 3-D Transport Code RADUGA

, 2005
Operational remote sensing of terrestrial atmosphere is heavily based on the 1-D radiative transfer equation. However, cloudy scenes are influenced by 3-D effects (e.g., illumination from cloud sides, etc.).
