Glycolyl-neuraminic Acid in Ox Brain Gangliosides [PDF]

Nature, 1965
IN this communication we report the presence of glycolyl-neuraminic acid in sialic acids from ox brain gangliosides. Our method of analysis consisted of the following six steps: (i) gangliosides were extracted from ox brain grey matter and purified according to a method which we have previously described1; (ii) gangliosides so obtained were hydrolysed ...

The N‐Glycome to Differentiate Mesenchymal Stem Cells Upon Chondrogenic Differentiation, Dedifferentiation, and Senescence

PROTEOMICS, Volume 26, Issue 7, Page 17-27, July 2026.
ABSTRACT Mesenchymal stem cells (MSCs) are adult stem cells able to self‐renewal or differentiation into different cell types, including chondrocytes. N‐Glycans are post‐translational modifications of glycoproteins that contribute to vital cell functions.

Oxalis corniculata L. Ethanol Extract Promotes Fracture Healing: Integrated Omics and Experimental Validation

Food Science &Nutrition, Volume 14, Issue 5, May 2026.
Oxalis corniculata L. ethanol extract (OCEE) showed efficacy in promoting fracture healing. A total of 549 compounds were identified by UHPLC‐Q‐Exactive‐MS/MS, with three key components recognized. OCEE may accelerate fracture healing by regulating TNFα, MMP9, ESR1, TP53, and related signaling pathways. ABSTRACT Oxalis corniculata L.

Safety of 3′‐sialyllactose (3′‐SL) sodium salt produced with a derivative strain (Escherichia coli K‐12 MG1655 INB‐3SL_01) of E. coli K‐12 MG1655 (ATCC 700926) as a novel food pursuant to Regulation (EU) 2015/2283

EFSA Journal, Volume 24, Issue 3, March 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 3′‐sialyllactose (3′‐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) 3′‐SL (sodium salt),
