Evaluation of Talbot's Safety Zone of Infusion Volume and Osmolality in Infusion Therapy for Decompensated Liver Cirrhosis
Problems with infusion therapy for correcting fluid and sodium imbalance in decompensated liver cirrhosis (DLC) were investigated by establishing the safety zone of Talbot et al. for parenteral fluid therapy in 4 DLC patients infused with over 900 ml of fluid each day for at least 9 days. The safety zone was different in each case. The safe infusion volume decreased and the safe electrolyte concentration shifted to a lower osmolality when there was ascites with renal failure than ascites without renal failure. Infusion therapy was performed without deterioration of the water and sodium balance in those patients whose infusion volume and fluid osmolality were in the safety zone. In contrast, ascites retention increased and peripheral edema appeared in patients whose infusion volume and osmolality were out of the safety zone. Therefore, the safety zone should be determined repeatedly during infusion therapy.</p
Technical Progress in Single-Incision Laparoscopic Cholecystectomy in Our Initial Experience
Single-incision laparoscopic cholecystectomy (SILC) has rapidly spread throughout the world because of its low invasiveness and because it is a scarless procedure. Various surgical methods of performing SILC are present in each institute; however, it is necessary to develop a standardized procedure that we can perform safely, such as the conventional 4-port laparoscopic cholecystectomy (LC). The SILC experiment in our institute was started by use of the commercial SILS Port and changed from a 3-port method via an umbilicus to a 2-port method to improve some problems. Although none of the conversions to conventional 4-port LC and also none of the complications such as bile duct injury occurred in each method, the 2-port method functioned best and was also economical. However, it is most important to adopt strict criteria and select the patients suitable for SILC to demonstrate SILC safety same as 4-port LC
Structural Parameterizations of Vertex Integrity
The graph parameter vertex integrity measures how vulnerable a graph is to a
removal of a small number of vertices. More precisely, a graph with small
vertex integrity admits a small number of vertex removals to make the remaining
connected components small. In this paper, we initiate a systematic study of
structural parameterizations of the problem of computing the
unweighted/weighted vertex integrity. As structural graph parameters, we
consider well-known parameters such as clique-width, treewidth, pathwidth,
treedepth, modular-width, neighborhood diversity, twin cover number, and
cluster vertex deletion number. We show several positive and negative results
and present sharp complexity contrasts.Comment: 21 pages, 6 figures, WALCOM 202
Resistive detection of the Néel temperature of Cr₂O₃ thin films
Although bulk magnetic properties of various antiferromagnets have been vigorously studied since long ago, their properties in the form of thin films, which are more relevant to antiferromagnetic spintronic devices, have not been investigated as much. In this work, we characterized the Néel temperature of Cr₂O₃ thin films by investigating the temperature dependence of the spin Hall magnetoresistance in Cr₂O₃/Pt bilayers. A precise determination of the Néel temperature was made possible by carefully designing the direction of the magnetic anisotropy in Cr₂O₃. The results provide a reliable way to determine the Néel temperature of antiferromagnetic thin films.Tatsuya Iino, Takahiro Moriyama, Hiroyuki Iwaki, Hikaru Aono, Yu Shiratsuchi, and Teruo Ono, Appl.
