Background: The aim of this study was to determine the effectiveness of oral administration of lemon/orange juice in improving the visualization of pancreatic ducts on MRCP.
Materials And Methods: MRCP images were generated before and at every 15 min for 90 min after oral administration of lemon/orange juice in a dose of 2 ml/kg in 20 volunteers and 26 patients. The pre- and post-administration images were compared and analyzed qualitatively and quantitatively.
Results: In 20 volunteers and 26 patients, the visualization at pancreatic duct of head, body, tail, accessory pancreatic duct, and branch duct was improved after juice administration. The diameter of pancreatic ducts was augmented, and the differences in the mean values before and after oral juice were highly significant at both sites in volunteers and patients (P < 0.01). In 20 volunteers and 26 patients, after juice administration, the best visualization of the pancreatic duct was achieved at (58.98 +/- 14.96) min and (59.41 +/- 13.79) min, respectively, and the overlap imaging of oral juice was especially observed at (42.86 +/- 10.92) min and (41.63 +/- 9.32) min, respectively.
Conclusions: Orally lemon/orange juice is an effective method to improve MRCP imaging of pancreatic ducts. The lemon/orange juice should be administered at 60 min prior to MRCP.

Background: Attractive toxic sugar bait (ATSB) is a promising "attract and kill"-based approach for mosquito control. It is a combination of flower nectar/fruit juice to attract the mosquitoes, sugar solution to stimulate feeding, and a toxin to kill them. Selecting an effective attractant and optimizing concentration of toxicant is significant in the formulation of ATSB.

Fermented beverages based on kombucha contain a wide range of minor biologically active substances (flavonoids, caffeic acid derivatives, B vitamins, and others). The inclusion of these beverages in the diet helps to increase its nutritional value due to the content of biologically active substances, including essential ones. To develop beverages (kombucha) with a certain content of biologically active substances, it is necessary to study the composition of these products sold on the Russian market.

In stage 1, the pH and titratable acidity of 5 commercially available powdered juices in 10 different flavors were analyzed. Five treatment groups were then established based on the pH values, titratable acidity, and presence of citric acid in the juices, and their energy-dispersive X-ray (EDX) spectroscopy profiles were studied.

To recycle the sharply growing spent lithium-ion batteries and alleviate concerns over shortages of resources, particularly Li, is still an urgent issue. In this work, an organic acids based leaching approach at room temperature is proposed to recover Li and FePO from spent LiFePO cathode powder. The coexistent metal ions, Cu and Al, have also been investigated.

The sour taste of Citrus fruits is due to the extreme acidification of vacuoles in juice vesicle cells via a mechanism that remained elusive. Genetic analysis in petunia identified two vacuolar P-ATPases, PH1 and PH5, which determine flower color by hyperacidifying petal cell vacuoles. Here we show that Citrus homologs, CitPH1 and CitPH5, are expressed in sour lemon, orange, pummelo and rangpur lime fruits, while their expression is strongly reduced in sweet-tasting "acidless" varieties.
