Abstract

High quality single crystals of PbMoO 4 useful for high resolution light deflectors have been grown by the Czochralski method using high frequency induction heating. High quality crystals were obtained following an investigation of the dependence of seed orientation on the generation of subgrains and subgrain boundaries generated at the seed interface, and grown into the crystal. A lot of subgrains occured for the seed orientations around the c -axis. High homogeneity single crystals were obtained by using seed orientations inclined more than 30° from the c -axis in the intermediate planes between the a - and b -plane. Though the subgrain boundaries have a tendency of continuation from the seed to the grown crystal, in the preferred seed orientations they were squeezed out at the shoulders of the grown crystals. The grown crystals were of optical glass quality.

Abstract

Introduction: Hypoxic pulmonary vasoconstriction optimises oxygenation in the lung by matching the local-blood perfusion to local-ventilation ratio upon exposure to alveolar hypoxia. It plays an important role in various pulmonary diseases, but few imaging evaluations of this phenomenon in humans. This study aimed to determine whether chest digital dynamic radiography could detect hypoxic pulmonary vasoconstriction as changes in pulmonary blood flow in healthy individuals., Methods: Five Asian men underwent chest digital dynamic radiography before and after 60 sec breath-holding at the maximal inspiratory level in upright and supine positions. Alveolar partial pressure of oxygen and atmospheric pressure were calculated using the blood gas test and digital dynamic radiography imaging, respectively. To evaluate the blood flow, the correlation rate of temporal change in each pixel value between the lung fields and left cardiac ventricles was analysed., Results: Sixty seconds of breath-holding caused a mean reduction of 26.7 ± 6.4 mmHg in alveolar partial pressure of oxygen. The mean correlation rate of blood flow in the whole lung was significantly lower after than before breath-holding (before, upright 51.5%, supine 52.2%; after, upright 45.5%, supine 46.1%; both P < 0.05). The correlation rate significantly differed before and after breath-holding in the lower lung fields (upright, 11.8% difference; supine, 10.7% difference; both P < 0.05). The mean radiation exposure of each scan was 0.98 ± 0.09 mGy. No complications occurred., Conclusions: Chest digital dynamic radiography could detect the rapid decrease in pulmonary perfusion in response to alveolar hypoxia. It may suggest hypoxic pulmonary vasoconstriction in healthy individuals., (© 2022 The Authors.

5. Spontaneous brain tumor imaging of aged rat by crystal X-ray interferometer-based phase-contrast X-ray CT.

Abstract

Background: Crystal X-ray interferometer-based phase-contrast X-ray computed tomography (C-PCCT) enables the depiction of internal structures of biological tissue without contrast agents., Purpose: To determine the advantage of this technique in visualizing detailed morphological structures of a rare spontaneous brain tumor in an aged rat., Material and Methods: An aged rat's spontaneous brain tumor was imaged by C-PCCT without contrast agent. Three-dimensional (3D) images of the tumor microvasculature were reconstructed and compared with pathological pictures., Results: C-PCCT depicted the tumor's various pathological features clearly, e.g. its cell density and vasculature, and blood clots caused by hemorrhaging and/or hematomas. The obtained images resembled pathological pictures with a magnification of ×20 and were used to reconstruct 3D images of the tumor vascularity up to approximately 26 µm in diameter., Conclusion: Since C-PCCT is able to depict various pathological conditions, it might be useful for cancer research.

Abstract

In the previous papers, we reported that predilution hemodiafiltration (HDF) has more beneficial effects on dialysis patients than postdilution HDF. The mechanism behind this has not yet been clarified, but some factors could explain the advantage, such as a well-balanced solute removal pattern, reduction in the small nutrient loss and biocompatibility. Generally, the efficacy of small solute and low-molecular-weight protein removal is better in postdilution HDF or hemodialysis than in predilution; however, the more efficient removal does not always lead to the improvement of patients' symptoms and feelings. This issue suggests that the biocompatibility is an essential aspect for evaluating the quality of dialysis modality. There are three possible mechanisms for the advantages of predilution on-line HDF in biocompatibility. First, a large amount of filtrate at the filter could drain away chemical-eluting substances from the dialysis membrane and some reactive proteins. Second, blood dilution could reduce the chance of blood cells to be in close contact with the dialysis membrane surface, and then it could reduce the sequential inflammatory response. Third, blood dilution itself reduces the production of free radicals. We believe the biocompatibility of predilution online HDF is closely related to the improvement of dialysis-related various symptoms., (Copyright © 2013 S. Karger AG, Basel.)
