A Novel Lineage of Endosymbiotic Actinomycetales: Genome Reduction and Acquisition of New Functions in Bifidobacteriaceae Associated With Termite Gut Flagellates

open access: yesEnvironmental Microbiology, Volume 27, Issue 1, January 2025.
We have characterised several novel genera of Bifidobacteriaceae that colonise the cytoplasm of cellulolytic flagellates. Horizontal gene transfer played an important role in their adaptation to the intracellular environment. However, progressive genome erosion led to the loss of biosynthetic capacities that formed the basis of an originally ...

Polysaccharides from the root of Angelica sinensis protect bone marrow and gastrointestinal tissues against the cytotoxicity of cyclophosphamide in mice [PDF]

open access: yes, 2006
Cyclophosphamide (CY) is a cytostatic agent that produces systemic toxicity especially on cells with high proliferative capacity, while polysaccharides from Angelica sinensis (AP) have been shown to increase the turnover of gastrointestinal mucosal and ...

Exploring the chemical composition and biological effects of four Salvia hybrids: an innovative perspective on functional yields

open access: yeseFood, Volume 5, Issue 5, October 2024.
It can be concluded that, genus Salvia, as one of the well‐known and phytochemically rich genera of family Lamiaceae, served here as a source of four hybrids which were evaluated as a potential source of biologically important metabolites Abstract Genus Salvia is considered one of the largest genera of family Lamiaceae with many recorded species and ...

Proteoglycans and osteolysis. [PDF]

open access: yes, 2012
Osteolysis is a complex mechanism resulting from an exacerbated activity of osteoclasts associated or not with a dysregulation of osteoblast metabolism leading to bone loss.

Heparin and heparan sulfate—The essence of sequence

open access: yesProteoglycan Research, Volume 2, Issue 4, October-December 2024.
Abstract Heparin, discovered as an anticoagulant more than 100 years ago, is composed of the same structural units as heparan sulfate, and their biosynthesis in the Golgi compartment is carried out by the same families of enzymes. However, while heparin is restricted to mast cells, heparan sulfate is widely distributed and is found at the cell surface ...

The Haemophilus influenzae HMW1C protein is a glycosyltransferase that transfers hexose residues to asparagine sites in the HMW1 adhesin [PDF]

open access: yes, 2010
The Haemophilus influenzae HMW1 adhesin is a high-molecular weight protein that is secreted by the bacterial two-partner secretion pathway and mediates adherence to respiratory epithelium, an essential early step in the pathogenesis of H.

Glycolanguage of the oral microbiota

open access: yesMolecular Oral Microbiology, Volume 39, Issue 5, Page 291-320, October 2024.
Oral bacteria speak a sophisticated glycolanguage transmitted through versatile glycoinfrastructure, carbohydrate‐active enzymes, and lectins, which contributes decisively to their success in the oral habitat. Deciphering this glycolanguage opens new avenues for novel antibacterials to treat oral diseases. Abstract The oral cavity harbors a diverse and

Ion Mobility Mass Spectrometry‐Based Disaccharide Analysis of Glycosaminoglycans

open access: yesChemistry – A European Journal, Volume 30, Issue 35, June 20, 2024.
Glycosaminoglycans (GAGs) are vital polysaccharides with complex structures. Disaccharide analysis, involving enzymatic depolymerization and liquid chromatography, is commonly used for their analysis. Here, direct infusion nESI ion mobility‐mass spectrometry (IM‐MS) is used to reduce measurement time from hours to minutes.

The crucial evaluation indexes and relative measurement methods of edible value for fresh fruits and vegetables: A review

open access: yesFuture Postharvest and Food, Volume 1, Issue 2, Page 222-236, June 2024.
Abstract Fresh fruits and vegetables (F&V), with their attractive sensory, flavors, and nutrients, occupy a highly valuable part of people's daily diet. Plenty of postharvest studies have focused on the effects of preservation techniques on the edible quality and nutrients of F&V.

Sweet but Challenging: Tackling the Complexity of GAGs with Engineered Tailor‐Made Biomaterials

open access: yesAdvanced Materials, Volume 36, Issue 11, March 14, 2024.
The field of biomaterials presenting glycosaminoglycans (GAGs) is an emerging field. Some of these biomaterials are applied for regenerative medicine but in vivo GAGs are highly diverse. Here, the methods employed to understand the complexity of GAGs are reviewed.
