Effect of PG-SPI and PG-KII, two novel and natural tachykinins, on salivary secretion in the rat
Peptides, 1996Co-Authors: Maria Broccardo, Giovanna Improta, A. Brandoni, Alessandra TabaccoAbstract:Abstract In an in vivo study of salivation in rats, the scialogogic effects of two natural and amphibian tachykinins, PG-SPI and PG-KII, which activate distinct tachykinin receptors, were compared with those of the tachykinins substance P, neurokinin A and B, and kassinin. The rank order of potencies of these peptides injected intravenously on salivation was: PG-SPI = SP ≥ PG-KII = KASS > NKA ⪢ NKB. Atropine (1 mg/kg, IV) had no effect on PG-SPI-, SP-, and NKA-induced salivation, but reduced that stimulated by PG-KII and KASS. We conclude that PG-SPI and PG-KII increase salivary secretion through different mechanisms and that rat salivary glands contain PG-SPI- and PG-KII-sensitive receptors.

A DeSalination Battery Combining Cu3[Fe(CN)6]2 as a Na-Storage Electrode and Bi as a Cl-Storage Electrode Enabling Membrane-Free DeSalination
2019Co-Authors: Do-hwan Nam, Margaret A. Lumley, Kyoung-shin ChoiAbstract:A deSalination battery is an attractive route for seawater deSalination because it couples ion removal with energy storage. In this work, we paired Cu3[Fe(CN)6]2·nH2O as the Na-storage electrode with Bi as the Cl-storage electrode to construct a novel deSalination battery that enables membrane-free deSalination. Most current deSalination technologies, with the exception of thermal distillation, rely on the use of membranes. Eliminating the need for a membrane can significantly simplify the construction and maintenance of deSalination systems. After carefully examining the sodiation/desodiation reactions and cycle performance of Cu3[Fe(CN)6]2·nH2O in both acidic and neutral saline solutions (0.6 M NaCl), we combined Cu3[Fe(CN)6]2·nH2O with Bi, which was previously identified as a promising Cl-storage electrode, to construct a Cu3[Fe(CN)6]2·nH2O/Bi deSalination battery. The Cu3[Fe(CN)6]2·nH2O/Bi deSalination battery generates an electrical energy output during deSalination, which is equivalent to discharging, and requires an electrical energy input during Salination, which is equivalent to charging. We investigated optimum pH conditions to perform Salination to minimize the energy necessary for charging so that the deSalination/Salination cycle could be achieved with a minimum overall energy input. The results obtained in this study suggest that with further optimization the Cu3[Fe(CN)6]2·nH2O/Bi deSalination battery will offer new possibilities for practical seawater deSalination

bismuth as a new chloride storage electrode enabling the construction of a practical high capacity deSalination battery
Journal of the American Chemical Society, 2017Co-Authors: Kyoung-shin ChoiAbstract:Materials that can selectively store Na and Cl ions in the bulk of their structures and release these ions with good cycle stability can enable the construction of a high capacity, rechargeable deSalination cell for use in seawater deSalination. In this study, the ability of a nanocrystalline Bi foam electrode to serve as an efficient and high capacity Cl-storage electrode using its conversion to BiOCl was investigated. When Bi as a Cl-storage electrode was coupled with NaTi2(PO4)3 as a Na-storage electrode, a new type of rechargeable deSalination cell, which is charged during deSalination and discharged during Salination, was constructed. The resulting Bi-NaTi2(PO4)3 cell was tested under various Salination and deSalination conditions to investigate advantages and potential limitations of using Bi as a Cl-storage electrode. Slow Cl– release kinetics of BiOCl in neutral conditions and an imbalance in Cl and Na storage (i.e., Cl storage requires three electrons/Cl, while Na storage requires one electron/Na...

The resulting Bi-NaTi2(PO4)3 cell was tested under various Salination and deSalination conditions to investigate advantages and potential limitations of using Bi as a Cl-storage electrode. Slow Cl– release kinetics of BiOCl in neutral conditions and an imbalance in Cl and Na storage (i.e., Cl storage requires three electrons/Cl, while Na storage requires one electron/Na) were identified as possible drawbacks, but strategies to address these issues were developed. On the basis of these investigations, optimum deSalination and Salination conditions were identified where the Bi/NaTi2(PO4)3 cell achieved a deSalination/Salination cycle at ±1 mA cm–2 with a net potential input of only 0.20 V. The kinetics of Cl– release from BiOCl was significantly improved by the use of an acidic solution, and therefore, a divided cell was used for the Salination process. We believe that with further optimizations the Bi/BiOCl electrode will enable efficient and practical deSalination applications

evaluation of the relationship between salivation ability and blood flow velocity in the submandibular gland using pulsed doppler ultrasonography
Oral Radiology, 2013Co-Authors: Kouji Katsura, Kayoko Ito, Kaname Nohno, Saori Funayama, Mikiko Saito, Takafumi HayashiAbstract:To investigate the possibility of predicting salivation ability using pulsed Doppler ultrasonography. Thirty healthy volunteers were enrolled in this study. The blood flow velocity in the submandibular gland before and during acid stimulation was recorded by pulsed Doppler ultrasonography. The changes in the maximum blood flow velocity (V max) and minimum blood flow velocity (V min) were analyzed and compared with the salivation abilities. Strong linear correlations between before and during acid stimulation were observed in the amount of salivation (R = 0.879, p < 0.05) and the V max (R = 0.938, p < 0.05). The mean change rate in the stimulated V max was 1.58 (range 1.10–4.58), and the mean (range) change rates in the V max after 1, 3, and 5 min of acid stimulation were 0.96 (0.47–1.47), 0.97 (0.79–1.40), and 0.98 (0.70–1.23), respectively. No strong linear correlation was observed between the amount of salivation and the blood flow velocity. Although it is known that an increase in the amount of salivation is closely related to an increase in the blood flow velocity in the salivary glands, our findings did not show a linear correlation between the amount of salivation and the blood flow velocity.
