Structure of glassy lithium sulfate films sputtered in nitrogen (LISON): Insight from Raman spectroscopy and ab initio calculations [PDF]

open access: yes, 2007
Raman spectra of thin solid electrolyte films obtained by sputtering a lithium sulfate target in nitrogen plasma are measured and compared to ab initio electronic structure calculations for clusters composed of 28 atoms. Agreement between measured and calculated spectra is obtained when oxygen atoms are replaced by nitrogen atoms and when the nitrogen ...

Avian neural crest cell migration is diversely regulated by the two major hyaluronan-binding proteoglycans PG-M/versican and aggrecan [PDF]

open access: yes, 2000
It has been proposed that hyaluronan-binding proteoglycans play an important role as guiding cues during neural crest (NC) cell migration, but their precise function has not been elucidated.

Proteoglycans and Hyaluronan in Normal and Aberrant Lung Development

open access: yesProteoglycan Research, Volume 3, Issue 2, April 2025.
ABSTRACT Lung development is a tightly regulated process that progresses through five distinct stages: embryonic, pseudoglandular, canalicular, saccular, and alveolar. Each stage is characterized by coordinated cellular interactions and structural changes driven by signals from epithelial, endothelial, and mesenchymal cells.

Exploring PtSO$_4$ and PdSO$_4$ phases: an evolutionary algorithm based investigation [PDF]

open access: yesPhys. Chem. Chem. Phys. 17, 18146 (2015), 2015
Metal sulfate formation is one of the major challenges to the emissions aftertreatment catalysts. Unlike the incredibly sulfation prone nature of Pd to form PdSO$_4$, no experimental evidence exits for the PtSO$_4$ formation. Given the mystery of nonexistence of the PtSO$_4$, we explore the PtSO$_4$ using a combined approach of evolutionary algorithm ...

Transition to Piscivory Seen Through Brain Transcriptomics in a Juvenile Percid Fish: Complex Interplay of Differential Gene Transcription, Alternative Splicing, and ncRNA Activity

open access: yesJournal of Experimental Zoology Part A: Ecological and Integrative Physiology, Volume 343, Issue 2, Page 257-277, March 2025.
ABSTRACT Pikeperch (Sander Lucioperca) belongs to main predatory fish species in freshwater bodies throughout Europe playing the key role by reducing planktivorous fish abundance. Two size classes of the young‐of‐the‐year (YOY) pikeperch are known in Europe and North America.

Aggrecan structure in amphibian cartilage

open access: yesBrazilian Journal of Medical and Biological Research, 2000
The structure of the large proteoglycan present in the bullfrog epiphyseal cartilage was studied by immunochemical and biochemical methods. The isolated monomer showed a polydisperse behavior on Sepharose CL2B, with a peak at Kav = 0.14.

Enzyme Replacement Therapy With Elosulfase Alfa Decreases Storage of Glycosaminoglycan in White Blood Cells of Patients With Morquio A Syndrome

open access: yesJournal of Inborn Errors of Metabolism and Screening, 2015
Mucopolysaccharidosis IVA (MPS IVA; Morquio A syndrome) is a lysosomal storage disorder caused by a deficient N-acetylgalactosamine-6-sulfate sulfatase activity, leading to cellular storage of undegraded keratan sulfate.

Quantification of sulfated polysaccharides in urine by the Heparin Red mix-and-read fluorescence assay [PDF]

open access: yesarXiv, 2018
Quantification of sulfated polysaccharides in urine samples is relevant to pharmacokinetic studies in drug development projects and to the non-invasive diagnosis and therapy monitoring of mucopolysaccharidoses. The Heparin Red Kit is a particularly simple and user friendly fluorescence assay for the quantification of sulfated polysaccharides and has ...

Retrospective Study of Clinical and Genetic Profiles of Alpha‐Mannosidosis Patients From the UAE

open access: yesJIMD Reports, Volume 66, Issue 2, March 2025.
ABSTRACT Alpha‐mannosidosis (AM; OMIM 248500) is a rare autosomal recessive lysosomal storage disorder caused by mutations in MAN2B1, which codes for the lysosomal alpha‐mannosidase enzyme (LAMAN; EC:3.2.1.24). Clinical characteristics include developmental delay, hearing impairment, and recurrent infections.

Ultrasensitive quantification of dextran sulfate by a mix-and-read fluorescent probe assay [PDF]

open access: yesarXiv, 2017
Dextran sulfate is semi-synthetic, polydisperse sulfated polysaccharide with important applications in clinical practice, in the manufacturing of plasma derived protein therapeutics and in biomedical research. The sensitive detection of dextran sulfate is relevant to preclinical and clinical drug development projects, the quality control of ...
