Osmolytes as Cryoprotectants Under Salt Stress

ACS Biomaterials Science & Engineering, 2023
Cryoprotecting agent (CPAs)-guided preservation is essential for effective protection of cells from cryo-injuries. But current cryoprotecting technologies practised to cryopreserve cells for biomedical applications are met with extreme challenges due to associated toxicity of CPAs.

Faecal Microbiota Transplantation in Anorexia Nervosa: A Systematic Review of Methodologies, Outcomes, and Challenges With Recommendations for Future Studies

European Eating Disorders Review, EarlyView.
ABSTRACT Objective Anorexia nervosa (AN) is a severe psychiatric disorder displaying an altered gut microbiome. Faecal microbiome transplantation (FMT) has emerged as a powerful research tool and potential treatment option in AN due to the microbiome‐gut‐brain axis. Current studies are limited and reveal variable FMT protocols.

Optimization of Sperm Cryopreservation Protocol for Peregrine Falcon (Falco peregrinus)

Animals, 2020
Sperm cryopreservation is a complex process that needs to be adapted to wild and domestic avian species to ensure proper efficiency. Because of its accessibility, the peregrine falcon may be used as a good model for studying other raptor species. To find

Climate Change Has Already Reshaped North American Forest Pest Dynamics: Insights From Multidecadal Process‐Based Modelling

Global Change Biology Communications, EarlyView.
Climate change has rapidly expanded and shifted suitable climate conditions for eight major forest pests across North America, especially toward northern and higher elevation areas. Host exposure and overlap among pests are increasing, raising ecological and economic risks, and signaling accelerating future impacts under continued warming.

REVIEW: Current Status of Extenders and Cryoprotectants on Fish Spermatozoa Cryopreservation [PDF]

, 2005
An important component of many studies of cryopreservation of fish spermatozoa is the type of extenders and cryoprotectants. The suitability of extenders and cryoprotectants differs from one fish to another.

Insights Into the Carboxyltransferase Reaction of Pyruvate Carboxylase From the Structures of Bound Product and Intermediate Analogs [PDF]

, 2013
Pyruvate carboxylase (PC) is a biotin-dependent enzyme that catalyzes the MgATP- and bicarbonate-dependent carboxylation of pyruvate to oxaloacetate, an important anaplerotic reaction in central metabolism.

Genetic suppression of cryoprotectant toxicity

Cryobiology, 2019
We report here a new, unbiased forward genetic method that uses transposon-mediated mutagenesis to enable the identification of mutations that confer cryoprotectant toxicity resistance (CTR). Our method is to select for resistance to the toxic effects of M22, a much-studied whole-organ vitrification solution.
