Mutarotational Kinetics and Glass Transition of Lactose

open access: yes, 2006
We report for the first time real time in situ and quantitative measurements of the mutarotation reaction of lactose in the solid state. The experiments have been performed by 13C NMR. We show that mutarotation is initiated on heating the amorphous state,

Protection of liposomes against fusion during drying by oligosaccharides is not predicted by the calorimetric glass transition temperatures of the dry sugars [PDF]

open access: yes, 2008
Sugars play an important role in the desiccation tolerance of most anhydrobiotic organisms. It has been shown in previous studies that different structural families of oligosaccharides have different efficacies to interact with phospholipid headgroups ...

Biomorph Soft Actuators with Tardigrade‐Like Resilience

open access: yesAdvanced Functional Materials, Volume 34, Issue 46, November 12, 2024.
Biomorph soft actuators, made of dual‐layer hydrogel spheres with embedded fluid bubbles, can replicate the unique adaptability features of tardigrades, including their dehydration and rehydration mechanisms. These smart structures are highly resilient to compressive, thermal, and radiation stimuli, demonstrating advanced capabilities such as driving ...

Carbon balance: A technique to assess comparative photosynthetic physiology in poikilohydric plants

open access: yesApplications in Plant Sciences, Volume 12, Issue 5, September-October 2024.
Abstract Premise Poikilohydric plants respond to hydration by undergoing dry–wet–dry cycles. Carbon balance represents the net gain or loss of carbon from each cycle. Here we present the first standard protocol for measuring carbon balance, including a custom‐modified chamber system for infrared gas analysis, 12‐h continuous monitoring, resolution of ...

Biomolecule surface patterning may enhance membrane association

open access: yes, 2012
Under dehydration conditions, amphipathic Late Embryogenesis Abundant (LEA) proteins fold spontaneously from a random conformation into alpha-helical structures and this transition is promoted by the presence of membranes.

A first look into moss living tardigrades in boreal peatlands

open access: yesEcology and Evolution, Volume 14, Issue 8, August 2024.
We investigate for the first time tardigrade community composition in boreal peatlands. Tardigrades are common in boreal peatlands and their abundance and community composition varies across peatland habitat types and microhabitats within peatlands. Abstract Tardigrades (Tardigrada) are a phylum of micrometazoans found in all biomes on Earth, but their

Response of a Terrestrial Polar Ecosystem to the March 2022 Antarctic Weather Anomaly

open access: yesEarth's Future, Volume 12, Issue 8, August 2024.
Abstract Record high temperatures were documented in the McMurdo Dry Valleys, Antarctica, on 18 March 2022, exceeding average temperatures for that day by nearly 30°C. Satellite imagery and stream gage measurements indicate that surface wetting coincided with this warming more than 2 months after peak summer thaw and likely exceeded thresholds for ...

Comparative genomics of the tardigrades Hypsibius dujardini and Ramazzottius varieornatus.

open access: yesPLoS Biology, 2017
Tardigrada, a phylum of meiofaunal organisms, have been at the center of discussions of the evolution of Metazoa, the biology of survival in extreme environments, and the role of horizontal gene transfer in animal evolution.

Development of a Tet-On Inducible Expression System for the Anhydrobiotic Cell Line, Pv11

open access: yesInsects, 2020
The Pv11 cell line established from an African chironomid, Polypedilum vanderplanki, is the only cell line tolerant to complete desiccation. In Pv11 cells, a constitutive expression system for Pv11 cells was previously exploited and several reporter ...

Anhydrobiosis in Yeasts: Changes in Mitochondrial Membranes Improve the Resistance of Saccharomyces cerevisiae Cells to Dehydration–Rehydration

open access: yesFermentation, 2019
Anhydrobiosis is a unique state of live organisms in which their metabolism is temporary reversibly suspended as the result of strong dehydration of their cells.
