When a freely suspended liquid film ruptures, it retracts spontaneously under the action of surface tension. If is surrounded by air, retraction velocity known to approach constant Taylor–Culick velocity. However, when an external viscous medium, dissipation within that medium dictates magnitude In present work, we study (water) in oil ambient (two-phase retractions), and sandwiched between air...
Nixtamalization is a corn cooking process with the addition of calcium hydroxide. This study aims to determine best treatment combination between concentration Ca(OH)2 and temperature changes in physicochemical properties amylographic cornflour. research was conducted using completely randomized design factorial pattern two factors. Factor I: 1%, 2% 3% (w/v); II: 70️℃, 80️℃, 90️℃, 100️℃. The re...
We examined the expression of calcium transporter 1 (CaT1) and epithelial calcium channel (ECaC) mRNA in the duodenum and kidney of mice. Intestinal CaT1 mRNA level increased 30-fold at weaning, coincident with the induction of calbindin-D(9k) expression. In contrast, renal CaT1 and ECaC mRNA expression was equal until weaning when ECaC mRNA is induced and CaT1 mRNA levels fall 70%. Long- and s...
In osteoblastic ROS 17/2.8 cells, 1,25-(OH)2-vitamin D3 stimulates transcription of the extracellular matrix phosphoprotein osteopontin (OPN). We now show posttranslational regulation of OPN production by 1,25(OH)2D3. Prior to transcriptional up-regulation of OPN, 1,25-(OH)2D3 induces a shift in OPN isoelectric point (pI) from 4.6 to 5.1. Loading equal amounts of OPN recovered from ROS 17/2.8 c...
Ca(2+) is absorbed across intestinal epithelial monolayers via transcellular and paracellular pathways, and an active form of vitamin D(3), 1alpha,25-dihydroxyvitamin D(3) [1alpha,25(OH)(2)D(3)], is known to promote intestinal Ca(2+) absorption. However, the molecules driving the paracellular Ca(2+) absorption and its vitamin D dependency remain obscure. Because the tight junction proteins clau...
