Endometriosis of the Appendix Resulting in Perforated Appendicitis

Endometriosis is a relatively common disease among women of reproductive age. However, gastrointestinal endometriosis is rare and endometriosis of the appendix resulting in perforated appendicitis is even rarer. We experienced a case of endometriosis of the appendix manifesting as panperitonitis caused by perforation of the appendix. The patient was a 35-year-old woman who was hospitalized with an acute abdomen. She was diagnosed with panperitonitis and underwent urgent laparotomy. When perforation of the appendix was detected, appendectomy and intraperitoneal drainage were performed. Pathological examination revealed endometriosis extending from the muscularis propria to the subserosa, and a diagnosis of endometriosis of the appendix was made. We consider the relevant literature describing the mechanism by which endometriosis of the appendix occurs, and the association between endometriosis of the appendix and acute appendicitis

IS ACTN3 R577X GENOTYPE ASSOCIATED WITH WEIGHT-BEARING INDEX IN MALE COLLEGE STUDENTS?

The purpose of this study was to determine the association between weight-bearing index (WBI) and ACTN3 genotype in male college students. Subjects were healthy male college students aged 18 to 21 years old. The maximal static forces of knee extension (leg strength) of the subjects were measured, and WBI was calculated by dividing the leg strength by the subjects’ body weight. Genomic DNA was extracted from each subject using hair strands, and its base sequence determined genotypes in RR, RX, and XX. Welch-type ANOVA revealed that WBI in the XX type was greater than in the RR and RX types despite no significant difference in leg strength and lean body mass among genotypes. Although it is difficult to find apparent or direct evidence to explain this result, some inferences can be proposed, such as compensatory force exertion based on its muscle fibers, regulation in calcineurin via the α-actine-2 gene, or functional enhancement of myoglobin-based endurance slow muscles in XX type may increase muscular activities against gravity, making WBI greater

Analytical Evaluation for Seismic Behavior of Shore Structures on Liquefied Area During Earthquakes

In this paper, focusing on the caisson type quay wall, which is a typical gravity type of shore structures, the seismic behavior of the structures was discussed when the liquefaction occurs, by applying the dynamic response analysis and a simplified prediction method which was proposed by the authors. Firstly, a simplified and reasonable method for predicting the seismic behavior of shore structures during earthquakes was proposed. In the proposed analytical method, the structure is replaced by a simplified model, and the ground contacting the structure by subgrade springs. There are two types of subgrade springs employed as elasto-plastic spring and liquefied spring. Secondly, the seismic behavior of shore structures in liquefied areas was evaluated through case study by dynamic response analysis. As the result, it was elucidated that the residual horizontal displacement of structures depends on the maximum horizontal acceleration acting at the center of structures, and the duration of earthquake motion is closely related to the residual horizontal displacement. It is also confirmed that the residual horizontal displacement of irregular seismic wave is 1/3 to 2/3 times smaller than that of regular seismic wave. After then, in order to confirm the applicability of the proposed simplified prediction method, a case study was performed to compare the result of the simplified analysis with that of the dynamic response analysis. As the result, the relationships between the horizontal acceleration at ground surface and the residual horizontal displacement by both analyses without liquefaction showed a similar trend, while those with liquefaction showed different trends, which was due to the difference of evaluating the semi-liquefaction, It was confirmed that the proposed simplified prediction method was applicable to predicting the actual seismic behavior of shore structures with good accuracy by adequately adjusting the reduction ratio of liquefied spring in the semi-liquefaction condition

Flexible mirrorless laser based on a free-standing film of photopolymerized cholesteric liquid crystal

Optically pumped mirrorless laser action has been observed in a dye-doped flexible free-standing film of photopolymerized cholesteric liquid crystal (PCLC). In the PCLC film, self-organized helical structure acts as one-dimensional (1D) photonic crystal. At high excitation intensity above the threshold, a laser action is observed at an edge of the 1D photonic band of the PCLC helical structure. This PCLC film laser possesses an excellent mechanical flexibility, and the laser action is also observed in a bent film of PCLC. This implies that the one-dimensional periodic structure for the laser action is maintained even in the deformed film. Using such flexibility of the PCLC film, a focusing effect of laser emission is demonstrated in a circularly deformed film. Moreover, the helical pitch of the PCLC has no temperature dependence in contrast to that of unpolymerized cholesteric liquid crystal. This means that the operation wavelength of laser action is thermally stable, which is the great advantage for the device application.This article may be downloaded for personal use only.
