A New Era for Using Natural Pigments: The Case of the C50 Carotenoid Called Bacterioruberin

Biotechnology and Applied Biochemistry, EarlyView.
ABSTRACT Haloarchaea are extremophilic microorganisms belonging to the Archaea domain that require high salt concentrations to live, thus inhabiting ecosystems like salty ponds, salty marshes, or extremely salty lagoons. They are more abundant and widely distributed worldwide than initially expected.

Large Thermal Conductivity Differences between the Crystalline and Vitrified States of DMSO with Applications to Cryopreservation. [PDF]

PLoS ONE, 2015
Thermal conductivity of dimethyl-sulfoxide (DMSO) solution is measured in this study using a transient hot wire technique, where DMSO is a key ingredient in many cryoprotective agent (CPA) cocktails.

Bottom‐Up Ice Growth Geometry Attenuates Shear Stress and Improves the Cryopreservation of Hematopoietic Stem/Progenitor Cells Under Low DMSO Concentrations

Biotechnology and Bioengineering, EarlyView.
ABSTRACT Studies on cell cryopreservation have been limited by the complexity of the freezing process and challenges on controlling ice formation, managing cooling rates, and optimizing cryoprotectant concentrations. The objective of this study is to evaluate the impact of bottom‐up and conventional radial freezing on the viability of mammalian cells ...

Dynamic expression of lamin B1 during adult neurogenesis in the vertebrate brain

Developmental Dynamics, EarlyView.
Abstract Background In mammals, specific brain regions such as the dentate gyrus (DG) of the hippocampus and the subventricular zone (SVZ) of the lateral ventricles harbor adult neural stem/progenitor cells (ANSPCs) that give rise to new neurons and contribute to structural and functional brain plasticity.

System for and method of freezing biological tissue [PDF]

, 1978
Biological tissue is frozen while a polyethylene bag placed in abutting relationship against opposed walls of a pair of heaters. The bag and tissue are cooled with refrigerating gas at a time programmed rate at least equal to the maximum cooling rate ...

Effect of medicinal and food homologous plants polysaccharides on animal nutrition and health: A review

Food Biomacromolecules, EarlyView.
Abstract As one of the most important components of foods, animal meat provides a lot of protein, fat, and energy for humans. However, nutrition and health of animals directly affect the healthiness of human, especially antibiotic residues in animals induced by abuse of antibiotics.

Research Progresses in Vitrification by Minimum Volume Method

Zhileng xuebao, 2018
Vitrification is an effective method in the field of cryopreservation since it can prevent the formation of ice crystals. Vitrification requires ultra-fast cooling rates and high concentrations of cryoprotective agents.

Effect of different cryoprotectants on the structural preservation of follicles in frozen zebu bovine (Bos indicus) ovarian tissue [PDF]

, 2004
Cryopreservation of ovarian tissue is a new and promising technique for germ-line storage. The objective of this study was to evaluate the effect of four cryoprotectants (at two concentrations each) on the preservation of zebu bovine preantral follicles ...

Mechanosensitive Cell‐Laden Shape‐Memory Scaffolds Engineered via Cryogelation

Small Structures, EarlyView.
GelMA‐based shape‐memory scaffolds encapsulating human adipose‐derived stem cells are fabricated via cryogelation, showing rapid recovery and high cell viability. Under cyclic compression, they promoted mechanotransduction gene expression, and composite formulations (collagen/GelMA, dECM/GelMA) retained robust shape‐memory, highlighting their promise ...
