Untargeted Metabolomic and Lipidomic Profiles of Gingival Crevicular Fluid in the Context of Periodontitis

open access: yesJournal of Clinical Periodontology, EarlyView.
ABSTRACT Aim(s) This cross‐sectional clinical study aimed to explore the untargeted metabolomic and lipidomic profiles in gingival crevicular fluid (GCF) obtained from healthy individuals and patients with periodontitis. Materials and Methods GCF was collected from 17 periodontally healthy and 19 periodontitis patients.

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

Perinatal Gut Dysbiosis Reduces Milk Oligosaccharides via LPS‐Mediated Gut–Mammary Signaling in Mice

open access: yesFood Frontiers, Volume 7, Issue 2, March 2026.
Maternal gut dysbiosis elevates Gram‐negative bacterial lipopolysaccharide (LPS), which enters circulation and accumulates in mammary tissue. This compromises the blood–milk barrier and suppresses key enzymatic genes, ultimately reducing milk oligosaccharide synthesis and potentially affecting neonatal gut microbiota through breastfeeding.

The Role of the Hexosamine-Sialic Acid Metabolic Pathway Mediated by GFPT1/NANS in c-Myc-Driven Hepatocellular CarcinomaSummary

open access: yesCellular and Molecular Gastroenterology and Hepatology
Background & Aims: Hepatocellular carcinoma (HCC) frequently involves metabolic reprogramming, which promotes oncogenesis and metastasis. However, the underlying molecular mechanisms remain insufficiently explored.

Preferential Accumulation of 14C-N-Glycolylneuraminic Acid over 14C-N-Acetylneuraminic Acid in the Rat Brain after Tail Vein Injection. [PDF]

open access: yesPLoS ONE, 2015
The two main molecular species of sialic acid existing in nature are N-acetylneuraminic acid (Neu5Ac) and N-glycolylneuraminic acid (Neu5Gc). Neu5Ac is abundant in mammalian brains and plays crucial roles in many neural functions.

Sialylation patterns in cerebral amyloid angiopathy

open access: yesBrain Pathology, Volume 36, Issue 2, March 2026.
This study is the first to localize and evaluate sialylation modifications in the context of Alzheimer's Disease and Cerebral Amyloid Angiopathy, revealing a unique disease‐specific increase in intravascular sialylation. Abstract Glycosylation is the most common form of post‐translational modification in the brain and becomes significantly altered in ...

Abnormalities of glycosphingolipids in mucopolysaccharidosis type III B.

open access: yesJournal of Lipid Research, 1984
Glycosphingolipids from brain, liver, and spleen of a patient with mucopolysaccharidosis type III B were quantitatively analyzed. Neutral glycosphingolipids containing glucosylceramide, lactosylceramide, globotriaosylceramide, globotetraosylceramide, and

Treatment with Plasma Activated (Salt) Water Sterilizes Macromolecular Coatings While Maintaining Their Integrity and Functionality

open access: yesAdvanced Materials Interfaces, Volume 13, Issue 3, 3 February 2026.
PDMS samples were covalently coated with mucin glycoproteins and then treated with either plasma activated water (PAW) or saline (PAS) as a means of disinfection. The samples could be successfully sterilized without compromising the structural integrity or functionality of those coatings.

Absolute bioavailability and intravenous pharmacokinetics of N‐acetyl‐D‐mannosamine in humans

open access: yesBritish Journal of Clinical Pharmacology, Volume 92, Issue 2, Page 488-494, February 2026.
Aims N‐acetyl‐D‐mannosamine monohydrate (ManNAc) is a naturally occurring monosaccharide that has attracted considerable attention for its potential in treating GNE myopathy, a rare autosomal recessive muscle disorder. Despite its promise as an oral treatment, the absolute bioavailability of oral ManNAc has not been determined and there has been no ...

Metabolomic Insights Into the Impact of a Maternal Western‐Style Diet and Leptin Supplementation During Suckling on Adult Rat Offspring

open access: yesThe FASEB Journal, Volume 40, Issue 2, 31 January 2026.
Plasma metabolites in adult offspring reflecting metabolic programming during critical developmental windows. ABSTRACT Perinatal nutrition influences offspring metabolic phenotype and obesity risk. This study examines how a maternal obesogenic diet and offspring's leptin supplementation during suckling affect the metabolome in offspring adulthood ...
