Abstract
BACKGROUND The present study aimed to evaluate the effectiveness of using platelet-rich fibrin (PRF) as the apical matrix for the placement of MTA in nonsurgical endodontic therapy for teeth with periapical lesions and open apices. METHODS Twelve teeth from eleven patients with periapical periodontitis and open apices were enrolled in the study. Nonsurgical endodontic therapy was performed with the PRF used as an apical barrier and the MTA manipulated as an apical plug for further thermoplasticized gutta percha in the remaining part of the root canal. Clinical signs and periapical digital radiographs were recorded and analyzed to evaluate the curing progress after periodical follow-ups of 1, 3, and 6 months. The horizontal dimension of the periapical lesion was determined, and the changes in the dimensions were recorded each time. The Friedman test was used for statistical analysis, with P < .05 serving as the threshold for determining statistical significance. RESULTS All patients had no clinical symptoms after the first month of treatment, with a significant reduction in the periapical lesion after periodical appointments. CONCLUSIONS PRF is an effective barrier when combined with MTA for the treatment of teeth with periapical periodontitis and open apices.

Abstract
This paper presents a novel tattooing capsule endoscope (TCE) for delivering a certain amount of ink to the submucosal layer of digestive tract organs. A dual-function permanent magnet is used for locomotion and injection activation. The developed capsule endoscope can move actively in 5 DOF due to the interaction between the permanent magnet and a controllable external magnetic field produced by an electromagnet actuation system. In addition, the permanent magnet is involved in a specially designed mechanism to activate a process that creates a squeezing motion to eject the liquid from the storage room to the target. The dimension of the prototype is 12.5 mm in diameter and 34.6 mm in length. The proposed TCE is tested ex vivo using a fresh porcine small-intestine segment. We were able to direct the TCE to the target and deliver the tattoo agent into the tissue. The proposed mechanism can be used for drug delivery or lesion tattooing, as well as to accelerate the realization of the functional capsule endoscope in practice.

Abstract
From the leaves and roots of Polyscias fruticosa, eight new oleanolic acid saponins named polysciosides A to H were isolated together with three known saponins. The structures of the saponins were established by means of spectral data, particularly NMR, which included COSY, HSQC, HMBC, HOHAHA and ROESY techniques.

Abstract
The differential effects of extracted and synthetic atrial natriuretic factor (ANF) on arterial blood pressure, natriuresis, and cyclic GMP excretion were studied in normotensive (WKY) and spontaneously hypertensive (SHR and SHRSP) rats. Atrial extracts or synthetic (101-126)-ANF decreased arterial blood pressure in all tested animals, but the blood pressure-lowering effect was more pronounced in hypertensive than in normotensive rats. ANF-induced diuresis and natriuresis were two- to three-fold higher in the hypertensive groups. However, a several-fold increase in total urinary cyclic GMP level after the infusion of ANF was essentially equal in the three groups. Our data suggest that acute infusion of ANF reveals a defect of sodium and water handling in SHR. It is possible that this defect is located at the distal nephron, and is made apparent by the action of ANF on glomeruli via a cyclic GMP-induced vascular effect.
