Mass spectrometry imaging of N‐linked glycans: Fundamentals and recent advances

Mass Spectrometry Reviews, EarlyView.
Abstract With implications in several medical conditions, N‐linked glycosylation is one of the most important posttranslation modifications present in all living organisms. Due to their nontemplate synthesis, glycan structures are extraordinarily complex and require multiple analytical techniques for complete structural elucidation.

Uncertainty through polynomial chaos in the EEG problem [PDF]

, 2011
A sensitivity and correlation analysis of EEG sensors influenced by uncertain conductivity is conducted. We assume a three layer spherical head model with different and random layer conductivities. This randomness is modeled by Polynomial Chaos (PC).

Yield of Whole Genome Sequencing for Pathogenic Single Nucleotide Variants in Congenital Heart Disease: A Systematic Review and Meta‐Analysis

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective This systematic review and meta‐analysis aimed to assess the diagnostic yield of pathogenic or likely pathogenic (P/LP) single nucleotide variants (SNVs) using whole genome sequencing (WGS) in congenital heart disease (CHD). Methods A systematic search of three databases (2000–2024) was conducted, and two reviewers independently ...

Hypertrophic Cardiomyopathy as a Key Feature of MRAS‐Related Noonan Syndrome: New Case and Comprehensive Literature Review

Prenatal Diagnosis, EarlyView.
ABSTRACT Noonan syndrome (NS) is a rare multisystemic condition among the RASopathy group, characterized by a broad phenotypic spectrum and genetic variability. It results from pathogenic variants in genes regulating the RAS/MAPK pathway, affecting cell proliferation and differentiation.

Hox Gene Variation Drives Morphological Specialization of Humpback Grouper Cromileptes altivelis

Integrative Zoology, EarlyView.
Cromileptes altivelis exhibits a distinctive “sunken head and humpback” morphology, formed through cranial remodeling. Genetic analyses identified unique amino acid variants in Hoxa7a and Hoxa10b, with functional tests confirming their role in enhancing osteoblast activity and driving cranial remodeling.
