Complex regulation of Cav2.2 N-type Ca2+ channels by Ca2+ and G-proteins.
Published 2025-01-01“…Studies of these forms of regulation generally employ Ba2+ as the permeant ion, despite that Ca2+ -dependent pathways may impinge upon G-protein modulation. To address this possibility, we compared tonic G-protein inhibition of currents carried by Ba2+ (IBa) and Ca2+ (ICa) in HEK293T cells transfected with Cav2.2. …”

Novel risk loci encompassing genes influencing STAT3, GPCR, and oxidative stress signaling are associated with co-morbid GERD and COPD.
Published 2025-02-01“…The co-heritability of GERD and COPD was 39.7% (h2 = 0.397, SE = 0.074) and we identified several ancestry-independent loci associated with co-morbid GERD and COPD (within LINC02493 and FRYL) known to be involved in oxidative stress and G protein-coupled receptor (GPCR) signaling mechanisms. …”

High-power ultrasound pretreatment for enhanced protein extraction from lupin flour: Impact on yield, anti-technological and anti-nutritional factors, and techno-functional propert...
Published 2025-03-01“…Ultrasonic field was characterized by computing acoustic pressure from frequency spectra analysis.In general terms, pretreatment reduced noticeably ANF and ATF in both LF and protein isolate (LPI), while also producing a protein concentrate (LPC, avg. 65 g protein/100 g) with low ANF and ATF content. Total protein yield, adding LPC and LPI, was increased by 15 % due to the pretreatment, which also enhanced the techno-functional properties of LPI, such as water absorption index (avg. 26 %) and foaming (avg. 8 %) and emulsifying properties (avg. 14 %). …”

Quality Control of Fetal Wharton’s Jelly Mesenchymal Stem Cells-Derived Small Extracellular Vesicles
Published 2025-02-01“…Quantitatively, the protein and particle concentrations revealed that all the sEV preparations were “impure” with < 1.5 × 109 particles/μg protein. Albumin was co-isolated in all the sEV preparations.Conclusion: In short, all characterized and standardized individual and pooled sEV preparations were deemed “impure” due to albumin co-isolation using the TFF method. …”
