Synthesis of alpha- and beta-D-(1->-6)-C-disaccharides by Wittig olefination of formyl C-glycosides with glycopyranose 6-phosphoranes

open access: yes, 1997
The synthesis of (1→6)-C-disaccharides by Wittig condensation of formyl C-glycofuranosides and pyranosides with galacto- and glucopyranose 6-phosphoranes is described herein. The method involves the coupling of the sugar aldehydes with the ylides and the

Breaking the ice: multiple origins of ice‐binding/antifreeze proteins

open access: yesThe FEBS Journal, EarlyView.
Ice‐binding proteins (IBPs) evolved independently in many organisms during Cenozoic cooling and glaciation. In flounders, α‐helical IBPs evolved from an antiviral protein, while similar IBPs arose independently from different progenitors in three other fish lineages.

Effects of Sucrose and Trehalose Supplementation on Zebrafish (Danio rerio) Sperm Quality During Cold Storage. [PDF]

open access: yesReprod Domest Anim
ABSTRACT This study evaluated the effect of disaccharide supplementation on zebrafish sperm stored at 5°C for 24 h. Seven pooled replicates from 60 broodfish were used. Semen samples were initially cooled and, after 1 h, supplemented with either HBSS (E‐C), Sucrose 0.13M (E‐S13), Trehalose 0.13M (E‐T13) or Trehalose 0.26M (E‐T26).

Flowering Plant Species Differ in Their Suitability for Orius strigicollis (Poppius): Effects on Plant Preference, Longevity and Oviposition Under Laboratory Conditions

open access: yesJournal of Applied Entomology, EarlyView.
ABSTRACT Flowering plant species can support pest control by providing resources for natural enemies. Polyphagous predatory species of the genus Orius occur in many parts of the world and are widely used as biological control agents. They feed on several common pest species and can additionally utilize plant resources such as nectar and pollen.

Thermal behavior of some reducing disaccharides

open access: yes, 1980
Thermogravimetry was used to monitor the loss of weight of a series of reducing disaccharides during a heating process. The resulting heating-curves provide a kinetic fingerprint for the individual compounds.

Adaptation to extreme environments: A review of Antarctic fish physiology

open access: yesJournal of Fish Biology, EarlyView.
Abstract Having evolved in the chronically cold and thermally stable waters of the Southern Ocean (SO) for millions of years, Antarctic fish possess a suite of physiological specializations that enable them to survive at temperatures near the freezing point of seawater. Adaptations include the evolution of antifreeze proteins, modifications of membrane

1,2-Trans-Selective Synthesis of Glycosyl Boranophosphates and Their Utility as Building Blocks for the Synthesis of Phosphodiester-Linked Disaccharides

open access: yes, 2016
A highly 1,2-trans-selective synthesis of glycosyl boranophosphate derivatives by glycosylation of dimethyl boranophosphate with glycosyl iodides was developed.

Finding the sweet spot: An exploration of environmental factors to optimize Ulva carbohydrate content and composition

open access: yesJournal of Phycology, EarlyView.
Abstract Green macroalgae from the Ulva genus are rich in polysaccharides of interest, including ulvan, starch, and cellulose. However, their content and structure are impacted by environmental factors, which poses challenges for industrial applications, especially in the context of climate change.

Genome‐scale insights into metabolic streamlining and photosynthetic energy balance in the extremophile green alga Picocystis salinarum (Picocystophyceae, Chlorophyta)

open access: yesJournal of Phycology, EarlyView.
Abstract Picocystis salinarum is an early‐diverging chlorophyte and the sole described member of the Picocystophyceae, frequently dominating hypersaline and alkaline lakes despite extreme physicochemical constraints. To elucidate the genomic foundations of its ecological success, we generated a fully annotated, chromosome‐scale nuclear genome assembly ...

The Keystone‐Pathogen Hypothesis Updated: The Role of Porphyromonas gingivalis in Periodontitis

open access: yesJournal of Periodontal Research, EarlyView.
Porphyromonas gingivalis orchestrates a coordinated manipulation of immune and inflammatory responses in periodontal tissues which leads to the generation of a dysbiotic, subgingival biofilm community, and progression of periodontitis. The type 9 secretion system, lipid A modification, and the formation of outer membrane vesicles are important ...
