Automation in Oocyte and Ovarian Tissue Vitrification

open access: yes, 2022
Two hundred years have passed since the first description of supercooled water by Gay-Lussac to the recent reports of high survival rates of embryo and oocytes after vitrification.

Trions as Fundamental Species in Chemically Doped Polymer Semiconductors

open access: yesAdvanced Materials, EarlyView.
This work shows that exciton–charge carrier coupling in doped polymer semiconductors gives rise to multi‐particle states, including trions—quasiparticles consisting of two holes and one electron under p‐doping—and bound exciton‐hole pairs, as identified through spectroscopic and theoretical analysis.

Spermidine Supplementation Effectively Improves the Quality of Mouse Oocytes After Vitrification Freezing

open access: yesAntioxidants
The cryopreservation of oocytes through vitrification is imperative for the conservation of livestock germplasm resources. However, as oocytes exhibit significant oxidative stress and organelle damage following vitrification freezing, it is crucial to ...

Cryopreservation of Rat Bone Marrow Derived Mesenchymal Stem Cells by Two Conventional and Open-pulled Straw Vitrification Methods [PDF]

open access: yesCell Journal, 2009
Objective: Mesenchymal stem cells (MSCs) are obtained from a variety of sources, mainlythe bone marrow. These cells have a great potential for clinical research, however they cannotstay alive for long periods in culture.

Stimuli‐Responsive Hierarchical Structuring Controls Survival and Programs Hydrogelation of Supramolecular Metallofibers

open access: yesAdvanced Materials, EarlyView.
Aqueous Zn(II) Salphen metallofibers decorated with PNIPAM undergo reversible, multi‐stimuli‐responsive hierarchical bundling. This higher‐order structuring kinetically stabilizes the otherwise fragile assemblies against dilution, acidic hydrolysis, and transmetallation, enables selective sorting of responsive fibers, and programs hydrogelation at ...

Perbandingan Viabilitas Oosit Pascavitrifikasi pada Dua Tingkat Konsentrasi Sukrosa yang Berbeda

open access: yesMajalah Kedokteran Bandung, 2017
Vitrifikasi merupakan suatu teknik kriopreservasi tanpa disertai pembentukan kristal es, baik intraseluler maupun ekstraseluler. Tingkat keberhasilan vitrifikasi sangat dipengaruhi oleh jenis dan konsentrasi krioprotektan yang digunakan.

Stress Transfer Within Microphase‐Separated Structures: A Post‐Synthetic Strategy to Impart Mechanoresponsiveness to Block Copolymer Materials

open access: yesAdvanced Materials, EarlyView.
A domain‐engineered post‐functionalization strategy is presented to impart mechanochromism to styrene–butadiene–styrene (SBS) block copolymers by simple blending with a tetraarylsuccinonitrile (TASN) mechanophore‐containing polystyrene (PS‐TASN‐PS). The resulting materials exhibit reversible fluorescence under tensile deformation while preserving, or ...

Automated robotic vitrification of embryos

open access: yes, 2015
This paper reports the first robotic system for vitrification of mammalian embryos. Vitrification is a technique for preserving oocytes and embryos in clinical IVF (in vitro fertilization).

Cryopreservation of cell/hydrogel constructs based on a new cell-assembling technique [PDF]

open access: yes, 2009
Organ manufacturing products hold the promise to be used widely in the future for complex organ failings. The cryopreservation of the product is a very important step in the commercialization activities.

Beyond Nanoporosity: A CO2‐Conditioned Glassy Matrix Contributes to the Brittle‐to‐Ductile Transition of Nanocellular Polyetherimide

open access: yesAdvanced Materials, EarlyView.
The mechanical performance of nanocellular polyetherimide cannot be explained by nanoporosity alone. It is shown that CO2 saturation and desorption leave a distinct mechanical signature in the glassy matrix before foaming. This matrix contribution provides a new route to understand and optimize the brittle to ductile transition in nanocellular polymers.
