Gas–liquid chromatographic assay of lipid-bound sialic acids: measurement of gangliosides in brain of several species

open access: yesJournal of Lipid Research, 1970
A method is described for analysis of gangliosides by GLC assay of the sialic acid component. Mild acid treatment in methanol converted the latter to methyl ketoside methyl ester, which was then chromatographed as the TMS derivative.

Generation of α1,3-galactosyltransferase and cytidine monophospho-N-acetylneuraminic acid hydroxylase gene double-knockout pigs

open access: yesJournal of reproduction and development, 2015
Zinc-finger nucleases (ZFNs) and transcription activator-like effector nucleases (TALENs) are new tools for producing gene knockout (KO) animals. The current study reports produced genetically modified pigs, in which two endogenous genes were knocked out.

Role of sialic acid in brachyspira hyodysenteriae adhesion to pig colonic mucins [PDF]

open access: yes, 2019
Infection with Brachyspira hyodysenteriae results in mucoid hemorrhagic diarrhea. This pathogen is associated with the colonic mucus layer, mainly composed of mucins. Infection regulates mucin O-glycosylation in the colon and increases mucin secretion as

In Vitro Evaluation of Hemiarthroplasty Bearing Materials: A Scoping Review (Part I)

open access: yesJournal of Orthopaedic Research, EarlyView.
ABSTRACT Hemiarthroplasty is used to treat joint damage confined to one side, aiming to preserve the remaining healthy cartilage and bone while addressing conditions like femur fractures and osteonecrosis; however, challenges persist due to cartilage wear and inconsistent clinical outcomes.

Impact of N‐linked glycans on the dual short fibulin/LTBP‐4 axes regulating elastogenesis

open access: yesThe FEBS Journal, EarlyView.
Elastic fiber assembly is orchestrated by multiple glycoproteins. We delineate the molecular basis of two key axes involved in elastic fiber formation—LTBP‐4L/fibulin‐4 and LTBP‐4S/fibulin‐5. We show that N‐linked glycans on these glycoproteins regulate their interactions and conformations, both of which are critical aspects in elastic fiber formation.

Distribution of glycan motifs at the surface of midgut cells in the cotton leafworm (Spodoptera littoralis) demonstrated by lectin binding [PDF]

open access: yes, 2017
Glycans are involved in many biological phenomena, including signal transduction, cell adhesion, immune response or differentiation. Although a few papers have reported on the role of glycans in the development and proper functioning of the insect midgut,

Genetic Adaptation to Brackish Water and Spawning Season in European Cisco

open access: yesMolecular Ecology, EarlyView.
ABSTRACT How species adapt to diverse environmental conditions is essential for understanding evolution and the maintenance of biodiversity. The European cisco (Coregonus albula) is a salmonid that occurs in both fresh and brackish water, and this together with the presence of sympatric spring‐ and autumn‐spawning lacustrine populations provides an ...

Nitrogen assimilation by E. coli in the mammalian intestine

open access: yesmBio
Nitrogen is an essential element for all living organisms, including Escherichia coli. Potential nitrogen sources are abundant in the intestine, but knowledge of those used specifically by E. coli to colonize remains limited. Here, we sought to determine

Free and bound forms of sialic acid in blood plasma of patients with chronic lymphocytic leukemia

open access: yesRegulatory Mechanisms in Biosystems, 2015
The level of free and bound forms of sialic acids (SА) was investigated in chronic lymphocytic leukemia (CLL) and at different stages of receiving chemotherapy.
