Background: The balance of autonomic nervous system activity and its relationship with body composition, sleep quality, and activities of daily living among older people is still unclear. Purpose: This comparative case study examined the characteristics of body composition, sleep quality, and autonomic nerve activity in active older adults with a younger body age-calculated from age trends in body composition and basal metabolic rate. Methods: We selected two cases with a metabolic age younger than their actual age. They had good sleep quality, no sarcopenia, strong muscle and grip strength, and balanced autonomic nervous system activity. They were compared with two other age- and gender-matched cases, who had poor sleep quality, unbalanced autonomic nervous system activity, and had a physical age closer to their actual age. Results: Older adults with more muscle mass and higher basal metabolism were younger than their actual age, had a better sleep status, and had a good balance of autonomic nervous activity during exercise stimulation. They also had lower percentages of body and visceral fat and higher percentages of body water. Conclusion: Two cases had a metabolic age younger than their actual age were found to be much younger than their actual age. However, the older adults with normal muscle mass and basal metabolic rate had poor sleep status and no sympathetic hyperactivity during exercise simulation.

The near infrared (NIR) fluorescence enhancement by local surface plasmon resonanoce from arrayed gold (Au) nanoblocks was investigated by NIR fluorescent dyes, IR780, immobilized in hydrophobic DNA thin film on glass substrates, to clarify the gap mode effect on the fluorescence enhancement. In the substrate with Dimer type Au nanoblock arrangement, average total fluorescence intensity was larger by 10.0, 2.4, and 12.4 times for non-polarized, P- and S- polarization as compared with that on a glass substrate alone, respectively. These findings suggested that enhancement of excitation light intensity at nanogap in the Dimer type Au nanoblock arrangement affected the fluorescence intensity. Average total fluorescence intensity, on the other hand, was smaller by 0.63 times as compared with that on a glass substrate alone in the checkerboard type Au array. It is suggested that the fluorescence quenching was caused by the energy transfer from the excited state of IR780 to Au nanoblocks or by the increased deactivation of excited dye molecules induced by resonance with Au nanoblocks at the checkerboard arrangement. We have firstly achieved the NIR fluorescence enhancement by LSPR due to the gap mode.

Although the etiology of eosinophilic cholecystitis is still obscure, the postulated causes include allergies, parasites, hypereosinophilic syndrome, and eosinophilic gastroenteritis. It is sometimes accompanied by several complications, but a simultaneous onset with pericarditis is very rares. A 28-year-old woman complained of acute right hypocondrial pain and dyspnea associated with systemic eruption. Several imaging modalities revealed acute cholecystitis and pericarditis with massive pericardial effusion. A marked peripheral blood eosinophilia was observed, and the eruption was diagnosed as urticaria. Her serum had a high titer of antibody against Ascaris lumbricoides . Treatment with albendazole drastically improved all clinical manifestations along with normalization of the imaging features and eosinophilia. We report herein a rare case of simultaneous onset of acute cholecystitis and pericarditis associated with a marked eosinophilia caused by parasitic infection.

Backgrounds: Colorectal cancer is an important contributor to cancer morbidity and mortality. Given that many older adult patients often have concomitant diseases and impairments in organ function, they are at increased risk for chemotherapy toxicity. Therefore, it is important to identify prognostic factors in older patients undergoing chemotherapy. Methods: We performed a retrospective chart review of colorectal cancer patients treated at Nagoya Memorial Hospital between 2012 and 2017 and selected those who received chemotherapy for metastatic colon cancer. Overall survival was calculated from the beginning of chemotherapy until death or the most recent follow-up date. We used the Kaplan-Meier method to plot survival curves and performed a statistical comparison using a log-rank test. In addition, multivariate analysis was performed using stepwise Cox proportional hazards models. Finally, a comprehensive geriatric assessment was conducted for older patients. The chart review was approved by the ethics committee of Nagoya Memorial Hospital. Results: The overall survival of metastatic colon cancer patients was not markedly different between patients aged ≥ 65 years of age (N = 37). Neither lesion site nor the RAS status affected survival, whereas the usage of three kinds of cytotoxic agents prolonged longevity. In a multivariate analysis of patients ≥ 65 years of age, the only independent prognostic factor for survival was the functional capacity, as measured by the Tokyo Metropolitan Institute of Gerontology (TMIG) index of competence. Conclusions: A combination of the comprehensive geriatric assessment and TMIG index was useful for predicting the longevity in patients with metastatic colon cancer ≥ 65 years of age.

We present a rare case of a gastrointestinal stromal tumor (GIST) in the stomach with prominent calcifica-tion at presentation. A 61-year-old woman visited our hospital because of epigastric discomfort. A spherical calcified lesion with a diameter of about 30 mm was incidentally shown in the left upper quadrant on an abdominal X-ray. Computed tomography demonstrated that the tumor was growing from the upper gastric body, with calcification in the peripheral ring area. A laparoscopic partial gastrectomy was performed, and the resected specimen revealed a well-circumscribed tumor with exophytic growth from the gastric muscularis propria. Microscopic examination revealed spindle- shaped tumor cells with calcification and hemorrhage. Additionally, positive immunoreactivity of the tumor to KIT and CD34 and a low mitotic index resulted in the diagnosis of very low risk GIST. There are a few case reports of heavily calcified GIST, although solitary or punctate calcification of primary GIST has been reported in several case series. Dystrophic calcification of necrotic or degenerative tissue is the supposed cause of primary calcified GISTs. In contrast, appearance of calcification after administration of imatinib mesylate, which may be one indicator of disease response, is possibly caused by a different mechanism.

近年来人们已注意到汽车齿轮在制造技术上的显著变化,那就是在生产上需要提供一种柔性制造系统,用以制造多品种的齿轮而不降低原有的产量。主要由数控机床组成的这种系统,虽然具有很高的柔性,但仍然存在一个投资效益问题。解决的办法是要建立“一序一机”型生产线。即以最少的工序、最短的时间生产出齿轮来获取高效益。它必须通过平衡每一工序的生产能力和集多序为一序的办法才能达到。这样,除剃齿工序仍须从质量和柔性两方面加以慎重考虑外,滚压、齿端倒角和部分车工序均可由精锻取而代之。此外,切齿刀具近期也有了显著进展。如表面镀锡、粉末高速钢、CBN(立方氮化硼)磨料等均已投入使用,因此,切齿和磨齿能力已得到了尽可能的提高。

Pancreatoduodenectomy (PD) has been performed commonly, but the occurrence of pancreatic fistula (PF) is a critical trigger of complications, which are potentially life threatening, and is also associated with markedly prolonged hospitalization. Many techniques have been proposed for connecting the pancreatic stump with the gastrointestinal tract, stomach vs. jejunum, etc. Among the risk factors for PF, such as general patient factors or disease-related factors, the most important is the texture of the remnant pancreas. Surgical technique might be one improvable aspect that can reduce the pancreatic leakage rate, therefore;various methods of managing the pancreatic remnant have been studied. Methods of reconstruction between the remnant pancreas and the intestine include end-to-side with/without duct-to-mucosa anastomosis or end-to-end invagination styles, has been argued. Here, we review several trials for safety and methods of treating the pancreatic stump after PD, and demonstrate our experiences.

In this case study, we hypothesized that sympathetic nerve activity would be higher during conversation with PALRO robot, and that conversation would result in an increase in cerebral blood flow near the Broca’s area. The facial expressions of a human subject were recorded, and cerebral blood flow and heart rate variability were measured during interactions with the humanoid robot. These multimodal data were time-synchronized to quantitatively verify the change from the resting baseline by testing facial expression analysis, cerebral blood flow, and heart rate variability. In conclusion, this subject indicated that sympathetic nervous activity was dominant, suggesting that the subject may have enjoyed and been excited while talking to the robot (normalized High Frequency < normalized Low Frequency: 0.22 ± 0.16 < 0.78 ± 0.16). Cerebral blood flow values were higher during conversation and in the resting state after the experiment than in the resting state before the experiment. Talking increased cerebral blood flow in the frontal region. As the subject was left-handed, it was confirmed that the right side of the brain, where the Broca’s area is located, was particularly activated (Left < right: 0.15 ± 0.21 < 1.25 ± 0.17). In the sections where a “happy” facial emotion was recognized, the examiner-judged “happy” faces and the MTCNN “happy” results were also generally consistent.
