Two successful pregnancies obtained following oocyte vitrification and embryo re-vitrification

Reproductive BioMedicine Online, 2008
Recent clinical reports not only show that cryopreserved embryos can be successfully used for human fertility treatment, but also that cryopreserved oocytes may be used successfully as an adjunct to human assisted reproductive technologies. Vitrification is known to establish a glass-like solid state during the cooling process.

Hydrogels Incorporating Donor–Acceptor Stenhouse Adducts as a Platform for Photoinduced, On‐Off Switchable Release of Small Molecule Cargos

Macromolecular Rapid Communications, EarlyView.
Donor–acceptor Stenhouse aDdducts (DASAs) are known for their photoinduced tautomerization, which, when conjugated to block copolymers, can self‐assemble into tuneable polymersomes. These DASA‐polymersomes are being investigated for light‐controlled cargo release in biomedical applications.

Robust β‐myrcene block copolymer elastomeric vitrimers

Polymer International, EarlyView.
Myrcene‐based vitrimeric elastomers were compared: statistical (poly(styrene‐stat‐myrcene‐stat‐AAEMA)] versus ‘hard–soft’ diblock (poly(styrene)‐block‐poly(myrcene‐co‐AAEMA)). The diblock's ability to anchor the glassy poly(styrene) blocks in a self‐assembled microstructure was effective – leading to four times higher tensile stress and ten times ...

Inconclusive chromosomal assessment after blastocyst biopsy: prevalence, causative factors and outcomes after re-biopsy and re-vitrification. A multicenter experience

Human Reproduction, 2018
STUDY QUESTION Can a second round of biopsy, vitrification and chromosomal testing provide a valid diagnosis where the first attempt fails? SUMMARY ANSWER The risk of inconclusive chromosomal-assessment after trophectoderm biopsy was 2.5% but a further

Differential Proteomics of Large Extracellular Vesicles in Ovarian Cancer

PROTEOMICS, EarlyView.
ABSTRACT Diverse extracellular vesicles (EVs) are present in all body fluids; however, knowledge of large EVs (lEVs) remains limited. Molecular EV profiles vary depending on EV size and the physiological circulatory system, even within the same patient. In this study, we aimed to characterize the proteomic profile of IEVs in ovarian cancer patients and

N-acetylcysteine addition after vitrification improves oocyte mitochondrial polarization status and the quality of embryos derived from vitrified murine oocytes

BMC Veterinary Research, 2019
BackgroundVitrification is the safest method to cryopreserve oocytes, however the process alters mitochondrial function resulting from increased reactive oxygen species (ROS) production. Our aim was to alleviate ROS stress in vitrified mice oocytes using

Ionogel Actuators: A Review

SmartBot, EarlyView.
Ionogels dynamically and functionally couple ionic liquids with polymer networks, enabling multiscale programmable deformation and motion under electrical, magnetic, optical, thermal, humidity, and chemical stimuli. This article systematically elucidates the constituent components, structural design, and multiscale actuation mechanisms of ionogel ...

Parallels between the dynamics at the noise-perturbed onset of chaos in logistic maps and the dynamics of glass formation

, 2005
We develop the characterization of the dynamics at the noise-perturbed edge of chaos in logistic maps in terms of the quantities normally used to describe glassy properties in structural glass formers. Following the recognition [Phys. Lett. \textbf{A 328}

Stabilized Extracellular Vesicle Formulations for Inhalable Dry Powder Development

Small, EarlyView.
Extracellular vesicles (EVs) hold promise for chronic obstructive pulmonary disease (COPD) treatment but face challenges with storage and delivery. This study demonstrates the stabilization of lung fibroblast‐derived EVs using inulin, enabling freeze‐drying and spray‐drying.
