A carbohydrate-based mechanism of species recognition in sea urchin fertilization

Brazilian Journal of Medical and Biological Research, 2007
In the present review, we describe a systematic study of the sulfated polysaccharides from marine invertebrates, which led to the discovery of a carbohydrate-based mechanism of sperm-egg recognition during sea urchin fertilization.

Dicarboxymethyl Cellulose‐Based Mixed‐Matrix Membrane Adsorbers: Preparation, Characterization, and Protein Retention Performance

Journal of Applied Polymer Science, EarlyView.
Dicarboxymethyl cellulose is incorporated, for the first time, into a polyethersulfone membrane. The functional membranes are prepared using dimethyl isosorbide through combined non‐solvent and vapor‐induced phase separation. The resulting membranes exhibit porous structures and protein‐retention potential, highlighting the potential of this cellulose ...

Phylogeny of algal sequences encoding carbohydrate sulfotransferases, formylglycine-dependent sulfatases and putative sulfatase modifying factors

Frontiers in Plant Science, 2015
Many algae are rich sources of sulfated polysaccharides with biological activities. The physicochemical/rheological properties and biological activities of sulfated polysaccharides are affected by the pattern and number of sulfate moieties.

Compositionally Engineered Carboxymethyl Cellulose‐Based Optical Fibers With Exceptionally Low Optical Loss and Quantitative Humidity Sensing

Advanced Physics Research, EarlyView.
Carboxymethyl cellulose‐based biopolymer optical fibers are fabricated using aqueous wet spinning. The fibers exhibit record‐low optical attenuation in polysaccharide‐based waveguides while maintaining efficient transmission across the visible‐to‐near‐infrared region of the electromagnetic spectrum.

Heat Stress and Gut Microbiome Dynamics in Poultry: Interplay, Consequences, and Mitigation Strategies

Animal Research and One Health, EarlyView.
Heat stress disrupts gut microbial balance in poultry, impairing nutrient absorption and immunity. This review outlines the interplay between thermal stress and microbiome dynamics and discusses integrative mitigation strategies, probiotics, phytogenics, cooling systems, and genetic adaptation to enhance poultry resilience.

Antithrombotics from the Sea: Polysaccharides and Beyond

Marine Drugs, 2019
Marine organisms exhibit some advantages as a renewable source of potential drugs, far beyond chemotherapics. Particularly, the number of marine natural products with antithrombotic activity has increased in the last few years, and reports show a wide ...

A Metagenome‐Assembled Genome Catalog From the Global Ruminant Microbiomes

Animal Research and One Health, EarlyView.
The Ruminant Gastrointestinal MAG Catalog (RGMC) is a comprehensive global resource offering 40,812 strain‐level genomes across 53 bacterial and 4 archaeal classes. It greatly surpasses prior efforts in scale and diversity, serving as an essential foundation for research in ruminant nutrition, microbial function, and methane mitigation.

Structure and Bioactivity of Sulfated Polysaccharides

Trends in Glycoscience and Glycotechnology, 2003
グリコサミノグリカンを含む酸性多糖類は様々な化学的、生物学的な機能を示す。これらの機能の多くは硫酸基の存在に強く依存している。よってこれら多糖類の部分的硫酸化、完全硫酸化あるいは脱硫酸化などの化学的修飾は、硫酸化多糖の示す機能を制御できるものと期待されている。多糖類の化学的修飾に関する論文は数多く、私たちもこれまで多糖類の化学修飾のみならずその生物学的作用に関して検討してきた(構造-活性相関、SAR)。本論文では天然および化学修飾した多糖類の構造活性相関について最近の結果を示す。

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

Animal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of
