Neuraminic acid content of sputum in chronic bronchitis [PDF]

Thorax, 1972
The neuraminic acid content of sputum from 48 men with early chronic bronchitis has been estimated in samples collected over a period of three years. The results are compared with those from 29 advanced bronchitic patients and are related to the clinical features of both groups and to the physical and biological properties of the sputum.

Sialic Acid Sensing via Molecularly Imprinted Polymer on Laser‐Induced Graphene

Advanced Sensor Research, Volume 5, Issue 2, February 2026.
Sialic acid is an important biomarker for oral and overall health. Salivary levels of sialic acid are linked with oral cancer and other diseases. We develop a point‐of‐care sensor for sialic acid, based on molecularly imprinted aminophenylboronic acid electropolymerized onto laser‐induced graphene.

Antibody‐Targeted Artificial T Cell and Natural Killer Cell Derived Vesicles for Cancer Immunotherapy

Journal of Extracellular Vesicles, Volume 15, Issue 2, February 2026.
ABSTRACT T cell and NK92 cell‐derived extracellular vesicles or artificial cell‐derived vesicles (ACDVs) exhibit anti‐cancer effects through inherited cytotoxic proteins like perforin and granzyme or transmembrane receptors like FasL and TRAIL. The anti‐cancer potential of artificial T and NK vesicles has been improved by attaching targeting moieties ...

Harnessing the acceptor substrate promiscuity of Clostridium botulinum Maf glycosyltransferase to glyco-engineer mini-flagellin protein chimeras

Communications Biology
Several bacterial flagellins are O-glycosylated with nonulosonic acids on surface-exposed Serine/Threonine residues by Maf glycosyltransferases. The Clostridium botulinum Maf glycosyltransferase (CbMaf) displays considerable donor substrate promiscuity ...

Separation Methods Affect Glycan Patterns in Extracellular Vesicle Preparations From Canine Osteoblasts and Osteosarcoma Cells

Journal of Extracellular Biology, Volume 5, Issue 2, February 2026.
ABSTRACT Extracellular vesicles (EVs) are nanosized, membrane‐enclosed particles released by cells, facilitating intercellular communication via the transfer of bioactive molecules from producing to recipient cells. EVs are involved in several physiological and pathological processes, including cancer progression.

Intra‐ and Intermolecular Glycosylation of d‐Idopyranosyl and 6‐Deoxy‐d‐ido‐heptopyranosyl Donors: Toward the Repeating Unit of Campylobacter jejuni HS:4c Capsular Polysaccharide

European Journal of Organic Chemistry, Volume 29, Issue 4, January 26, 2026.
A comprehensive glycosylation study of diversely protected and activated d‐idopyranosyl and 6‐deoxy‐d‐ido‐heptopyranosyl donors using intra‐ and intermolecular coupling strategies is reported. Intramolecular aglycon delivery afforded 1,2‐cis‐β‐idopyranosides, while intermolecular glycosylation yielded chromatographically separable α‐ and β‐linked ...

Isolation of a Protease‐Producing Microbacterium From the Intestinal Tract of Ruditapes philippinarum and Its Probiotic Effects

Aquaculture Nutrition, Volume 2026, Issue 1, 2026.
Aquatic probiotics are generally recognized as safe and nontoxic live bacterial preparations, primarily sourced from the culturing environment or directly from aquatic organisms. Upon entering the aquatic environment, these probiotics are capable of colonizing both the surface and internal compartments of aquatic organisms, thereby enhancing their ...

Safety of 6′‐sialyllactose (6′‐SL) sodium salt produced with a derivative strain (Escherichia coli K‐12 MG1655 INB‐6SL_02) of E. coli K‐12 MG1655 (ATCC 700926) as a novel food pursuant to Regulation (EU) 2015/2283

EFSA Journal, Volume 24, Issue 1, January 2026.
Abstract Following a request from the European Commission, the EFSA Panel on Nutrition, Novel Foods and Food Allergens (NDA) was asked to deliver an opinion on 6′‐sialyllactose (6’‐SL) sodium salt as a novel food (NF) pursuant to Regulation (EU) 2015/2283. The NF is mainly composed of the human‐identical milk oligosaccharide (HiMO) 6’‐SL (sodium salt),

Characterization of Newly Discovered Polyester Polyurethane‐Degrading Methylobacterium aquaticum Strain A1

Journal of Basic Microbiology, Volume 65, Issue 10, October 2025.
ABSTRACT In this study, we present Methylobacterium aquaticum A1, a novel strain capable of degrading polyester polyurethane (PE‐PUR). The attachment of M. aquaticum A1 to PE‐PUR and its degradation capabilities were verified using Scanning Electron Microscopy (SEM) and Fourier‐Transform Infrared Spectroscopy (FT‐IR).

Beyond FimH: Diversity and Relevance of Carbohydrate‐Binding Fimbrial Proteins in Escherichia coli

ChemBioChem, Volume 26, Issue 17, September 15, 2025.
This review discusses fimbrial lectins found in Escherichia coli (E. coli) other than FimH, which could be targeted to treat E. coli pathogenicity as an alternative to antibiotic treatment. Escherichia coli (E. coli) is responsible for multiple diseases in humans and animals.
