Role of hexose monophosphate shunt in parathyroid hormone secretion [PDF]

open access: yes, 1983
The metabolism of labeled glucose by collagenase-dispersed bovine parathyroid cells was examined. When the medium calcium ion concentration was increased to 2.0 mM, the rate of 14CO2 release from [1-14C]glucose was increased 169 +/- 45% compared with the

Ion Activation Methods for Top‐Down Proteomics

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

Mass Spectrometry Insights Into Post‐Translational Modifications in Extracellular Vesicles

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Extracellular vesicles (EVs) are membrane‐enclosed structures secreted by virtually all living cells, serving as essential mediators of intercellular communication in both physiological and pathological processes. There is growing interest in their potential applications as biomarkers, therapeutic targets, and drug delivery systems, which ...

Phosphonomethyl analogues of hexose phosphates [PDF]

open access: yesBiochemical Journal, 1976
The analogue of fructose 1,6-bisphosphate in which the phosphate group, -O-PO3H2, on C-6 is replaced by the phosphonomethyl group, -CH2-PO3H2, was made enzymically from the corresponding analogue of 3-phosphoglycerate. It was a substrate for aldolase, which was used to form it, but not for fructose 1,6-bisphosphatase.

Hevea brasiliensis seeds: A novel sustainable feedstock for ethanol production

open access: yesVietnam Journal of Chemistry, EarlyView.
Abstract The rubber tree (Hevea brasiliensis) is cultivated on a large scale mainly for the extraction of latex in Brazil and Southeast Asia, also generating large quantities of seeds. These seeds currently do not have large‐scale applications and may thus be considered as a residue.

Wasteosomes accumulate in periventricular white matter hyperintensities and exhibit complex relationships with mixed pathology, sclerotic index, and perivascular space

open access: yesBrain Pathology, EarlyView.
In a mixed diagnostic cohort of pathologically diagnosed Alzheimer's disease, cerebrovascular disease, mixed pathology, and control tissue, we connected the histopathological wasteosome profile in periventricular (PV) brain sections to 7T FLAIR‐MRI confirmed PV white matter hyperintensities (WMHs), vascular stenosis and perivascular space size ...

SUT sucrose and MST monosaccharide transporter inventory of the Selaginella genome

open access: yesFrontiers in Plant Science, 2012
While most metazoa mainly use hexose transporters to acquire hexoses from their diet and as a transport form for distributing carbon and energy within their bodies, insects use trehalose and plants use sucrose as their major form for translocation. Plant
