Resting membrane potentials, electrical resistance, and coupling of chick retinal pigment epithelium cells in tissue culture have been measured with micropipette electrodes. Topical application of NaCl, KCl, MgCl2, and CaCl2 produce rapid, reversible changes in the membrane potentials of these cells. CaCl2 uniquely induces a slow hyperpolarizing wave that can lead to barrages of depolarizing ac...

Solanum asterophorum Mart. (Solanaceae) is a shrub popularly known as "jurubeba-defogo" in the northeast of Brazil. In the present work, the methanol extract (SA-MeOH, 3750 microg/mL) and isojuripidine (10(-7) - 3 x 10(-4) M), a steroidal alkaloid obtained from S. asterophorum Mart. leaves, inhibited phasic contractions induced by both 1 microM histamine [IC50 = (225.8 +/- 47.4), g/mL and (3.5 ...

in this study, ultrafiltrated feta cheese was prepared from cow’s milk ultrafiltraton retentate and soymilk blend. rennet and calcium chloride were used simultaneously as coagulant to coagulate cow’s milk proteins and soymilk proteins, respectively. then, the effect of storage period on physical (texture profile analysis test, penetration test), chemical (total solids, protein, fat) and sensory...

In Korea, for heavy metal-contaminated soil, there are insufficient basic data as well field application cases soil washing. This study was conducted to suggest the significant factors and optimal operation conditions maximum metal removal efficiency. Five types of washing solution [acid (HCl), citric acid, oxalic EDTA, CaCl2], time (10–360 min), solid-solution ratio (1:2–1:100) were selected o...

AIM To investigate the effect of accelerated-set mineral trioxide aggregate (MTA) on the proliferation and odontoblastic differentiation of human dental pulp cell niches (DPSC). METHODOLOGY ProRoot White MTA (WMTA; Dentsply Tulsa Dental, Johnson City, TN, USA) was mixed with various additives, which included distilled water, 2.5% disodium hydrogen phosphate (Na2 HPO4 ; Merck, Darmstadt, Germa...

In this paper, chitosan was grafted with acrylic acid and positively charged elements, a series of reinforced nanofiltration membranes were prepared by coating modified polymer polysulfone ultrafiltration membrane as support. The structure derivatives polymers characterized infrared spectrum, the scanning electron microscope atomic force microscope. performance composite closely related to elec...

In this study, the O3 and OH radical oxidation of 2,5-dimethylfuran (2,5-DMF) were investigated in two different chambers at (296±1) K atmospheric pressure to examine secondary organic aerosol (SOA) formation. Results for OH-photooxidation indicate that SOA yieldsdecrease (from 6.2 0.4) with rise 2,5-DMF concentration (from10 1000 ppb). absence NOx under high relative humidity (RH) conditions (...

Geopolymer cement (GPC) is an aluminosilicate-based binder that cost-effective and eco-friendly, with high compressive strength resistance to acid attack. It can prevent degradation when exposed carbon dioxide by virtue of the low calcium content aluminosilicate source. The effect concentration chloride (CaCl2) as accelerator on acoustic impedance GPC for well cement, while pressure temperature...

The effects of preharvest calcium chloride (CaCl2) treatment on some quality characteristics and bioactive compounds sweet cherry fruit (Prunus avium L. cvs. 0900 Ziraat, Sweetheart Merton Late) were investigated. CaCl2 (1%) solution was sprayed to the trees at 21 35 days after full bloom stage. served as control treated with distilled water same days. remarkably suppressed respiration rate inc...

in this study, we aimed to determine the effects of halo-priming on yield and yield components of four wheat cultivars in a saline soil. a field study was conducted in factorial based on randomized complete block design (rcbd). soil ph was 8/1 and electrical conductivity was 9 ds/m. wheat cultivars (falat, ghods, chamran and shoori4) were primed with cacl2 solutions (control, 0, 50 and 100 mm)....
