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

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.

The crystal structure of murine CMP-5-N-acetylneuraminic acid synthetase

open access: yes, 2003
Sialic acids are activated by CMP-5-N-acetylneuraminic acid synthetase prior to their transfer onto oligo- or polysaccharides. Here, we present the crystal structure of the N-terminal catalytically active domain of the murine 5-N-acetylneuraminic acid

Identification of the Genomic Etiology of Unexplained Congenital Problems in Pediatric Patients: First Reported Case With Coffin–Siris Syndrome and Sialuria From India

open access: yesClinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Coffin–Siris syndrome (CSS) (OMIM:614608) is a rare genetic disorder characterized by global developmental delay (GDD), speech impediment, coarse facial features, and hypoplastic or absent fifth fingernails/toenails. Genetic variants in the SMARCB1 gene are associated with CSS, benign tumors (schwannomas), and rhabdoid tumor predisposition ...

Antiviral Resistance Associated With Multiple Mutations Occurring in Seasonal Influenza A(H3N2) Virus in a Patient Treated With Oseltamivir

open access: yesClinical Case Reports, Volume 14, Issue 9, September 2026.
ABSTRACT Our case highlights the importance of early diagnosis in respiratory illness and timely detection of drug resistance so that antiviral treatment can be initiated and modified, particularly for high‐risk groups. Vaccination and early, carefully dosed antiviral treatment are key to mitigating severe influenza cases, especially in ...
