Complex regulation of Cav2.2 N-type Ca2+ channels by Ca2+ and G-proteins. by Jessica R Thomas, Jinglang Sun, Juan De la Rosa Vazquez, Amy Lee

“…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. …”

High-power ultrasound pretreatment for enhanced protein extraction from lupin flour: Impact on yield, anti-technological and anti-nutritional factors, and techno-functional propert... by Paola Navarro-Vozmediano, Esperanza Dalmau, Jose Benedito, Jose V. Garcia-Perez

“…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 %). …”
