Characteristics of shooting time of the world’s top level male archery athletes

The purpose of this study was to clarify the characteristic features of the shooting time of the world’s top-level male archery athletes. The matches used for this study were those from the 1/64th Elimination Round to the Finals in the Men’s Individual of the 44th World Outdoor Target Archery Championships. As representative of the world’s top athletes, the medalists from these competitions were studied; the mean time and the coefficient of variation of the mean for each phase of shooting were calculated, and compared to those of all the athletes who competed in matches from the 1/64th Elimination Round to the Finals. The results of the study showed for the different phases of shooting, the preparatory phase had the longest mean time regardless of the resulting scores (p＜0.05); the mean’s coefficient of variation was also large for this phase (p＜0.05). The mean time taken by the medalists for the preparatory phase was shorter than the mean time taken by the competing athletes for the same phase (p＜0.01). These results suggest that the characteristic feature of shooting time of the world’s top-level male archery athletes was a shorter duration of the preparatory phase

Fetal response to induced maternal emotions.

This study investigated the relationship between fetal movements and acute maternal emotional changes during pregnancy. Two empirically validated feature film clips were used for the external generation of two subjectively and facially well-characterized target emotions: happiness and sadness. We simultaneously monitored separate fetal arm, leg, and trunk movements by means of two ultrasound apparatuses while maternal emotions were manipulated by film clip presentation. The number of fetal arm movements, but not the duration, was increased when pregnant women were being shown a happy film. Both the number and the duration of fetal arm movements decreased with the sad film presentation. Neither the presentation of happiness nor the presentation of sadness affected fetal leg or trunk movements. These findings suggest that induced emotions in pregnant women primarily affect arm movements of their fetuses, and that positive and negative emotions have the opposite effects on fetus movement

Fetal Response to Mozart\u27s Music

Objective: This study aimed to determine whether fetal arm movements change when music is presented to the mother or directly to the fetus through the mother\u27s lower abdomen, and whether maternal mood influences changes in fetal arm movements. Methods: Using a diagnostic ultrasound apparatus, fetal arm movements were measured in 47 pregnant women in the 35-36th week of pregnancy. Subjects were divided into two groups: a maternal presentation group, in which the mothers listened to music through headphones; and a fetal presentation group, in which music was presented directly to the fetus through headphones placed on the mother\u27s abdomen. Fetal arm movements were observed and recorded by ultrasound for a total of 10 min (5 min without music followed by 5 min with music). The music used was Mozart\u27s Sonata for Two Pianos in D Major, K. 448. The Profile of Mood States-Brief Form (POMS) was used to investigate the influence of maternal mood on fetal arm movements. Results: In the maternal presentation group, changes in fetal arm movement did not differ between mothers with different moods. In the fetal presentation group, fetal arm movements increased when the mother was energetic and decreased when the mother lacked energy. Fetal arm movement also decreased when the mother had a high level of fatigue and increased when the mother had a low level of fatigue. Conclusion: Presenting music directly to the fetus while the mother is relaxed has the potential to increase fetal response to the music and may possibly promote fetal well-being

Laxative effects of agarwood on low-fiber diet-induced constipation in rats

<p>Abstract</p> <p>Background</p> <p>Agarwood (<it>Aquilaria sinensis</it>), well known as incense in Southeast Asia, has been used as a digestive in traditional medicine. We investigated the laxative effects of an ethanol extract of agarwood leaves (EEA) in a rat model of low-fiber diet-induced constipation.</p> <p>Methods</p> <p>A set of rats was bred on a normal diet while another set was placed on a low-fiber diet to induce constipation. The laxative effect of agarwood was then investigated on both sets of rats.</p> <p>Results</p> <p>Pretreatment of normal rats with single dose of EEA (600 mg/kg, p.o.) significantly increased frequency and weight of stools. Also, treatments with EEA (300 and 600 mg/kg, p.o.) for 14 days caused a significant increase in stool frequency and weight. Feeding of the animals with a low-fiber diet resulted in a decrease in stool weight, frequency, and water content and also delayed carmine egestion. A single treatment with EEA (600 mg/kg) or senna (150 and 300 mg/kg) significantly increased stool frequency, weight, and water content and also accelerated carmine egestion in the model rats. Once daily administrations of EEA (150 mg/kg), for 14 days, caused a significant increase in water content of stools. The higher doses of EEA (300 and 600 mg/kg) significantly increased frequency, weight, and water content of the stools while accelerating carmine egestion in the constipated rats. Senna (150 and 300 mg/kg) produced similar effect as the higher doses of EEA but, in addition, induced severe diarrhea.</p> <p>Conclusion</p> <p>These findings indicate that EEA has a laxative effect, without causing diarrhea, in a rat model of low-fiber diet-induced constipation. These findings suggest that EEA may be highly effective on constipation as a complementary medicine in humans suffering from life style-induced constipation.</p

Renal Function after Nephrectomy Influences the Risk of Cardiovascular Events

We retrospectively analyzed the factors related to postoperative cardiovascular (CV) events in patients undergoing partial nephrectomy (PN) or radical nephrectomy (RN) for clinical T1 renal cell carcinoma (RCC). We identified 570 patients who underwent PN or RN for T1 renal cell carcinoma between January 1998 and December 2009 at our institution and related hospitals. We determined the cumulative incidence rate of CV events and overall survival (OS) using Kaplan-Meier survival curves with a log-rank test, and we evaluated the risk for an increase in CV events and OS using Cox proportional hazard regression. Of the 570 patients, 171 underwent PN and 399 underwent RN. The type of surgery was not significantly related with CV events. The only factor that significantly increased the risk of CV events in both the univariate (HR 2.67, p=0.006) and multivariate analyses (HR 2.14, p=0.044) was a postoperative estimated glomerular filtration rate (eGFR) <45 ml/min/1.73 m2. Postoperative eGFR was also a significant risk factor for OS in the univariate analysis (HR 2.38, p=0.0104), but not in the multivariate model. Postoperative renal function was a significant independent predictor of the incidence of subsequent CV events

IMPROVEMENT OF EXPERIMENTTAL THEME ON EXPERIMENTS IN ATERIALS ENGINEERING

長岡工業高等専門学校物質工学科では，1年生から5年生までの各学年において学生実験（物質工学実験）を行っている．特に1年生で実施される物質工学実験（化学）は，基礎的かつ重要な実験項目や技法を習得する実験と位置付けられる．一般に化学系実験で定量分析を行うときには，0.0001gまではかることのできる直示天秤を使用する．その使用法を身につけるための実験を一年生時に行っている．以前は，四塩化炭素の分子量を測定する実験を行っていたが，四塩化水素の毒性とともに，実験にかかる時間が2時間以上と長いことが問題であった．そこで，比較的安全性を有し，かつ1時間程度でできる実験が必要になった．一方，2年生の実験の際，こぼれた水酸化ナトリウムが解けた潮解の現象を見て驚く学生がいた．そこで，水酸化ナトリウムが潮解するときの質量変化を利用した直示天秤の実験を組み立てることに取り組んだ

HbA1c and telemedicine during COVID-19

Aims/Introduction: To investigate whether the COVID-19 pandemic affected behavioral changes and glycemic control in patients with diabetes and to conduct a survey of telemedicine during the pandemic. Materials and Methods: In this retrospective study, a total of 2,348 patients were included from 15 medical facilities. Patients were surveyed about their lifestyle changes and attitudes toward telemedicine. Hemoglobin A1c (HbA1c) levels were compared among before (from June 1 to August 31, 2019) and in the first (from June 1 to August 31, 2020) and in the second (from June 1 to August 31, 2021) year of the pandemic. A survey of physician attitudes toward telemedicine was also conducted. Results: The HbA1c levels were comparable between 2019 (7.27 ± 0.97%), 2020 (7.28 ± 0.92%), and 2021 (7.25 ± 0.94%) without statistical difference between each of those 3 years. Prescriptions for diabetes medications increased during the period. The frequency of eating out was drastically reduced (51.7% in 2019; 30.1% in 2020), and physical activity decreased during the pandemic (48.1% in 2019; 41.4% in 2020; 43.3% in 2021). Both patients and physicians cited increased convenience and reduced risk of infection as their expectations for telemedicine, while the lack of physician–patient interaction and the impossibility of consultation and examination were cited as sources of concern. Conclusions: Our data suggest that glycemic control did not deteriorate during the COVID-19 pandemic with appropriate intensification of diabetes treatment in patients with diabetes who continued to attend specialized diabetes care facilities, and that patients and physicians shared the same expectations and concerns about telemedicine

The Feature of Solitary Small Nodular Type of Hepatic Epithelioid Hemangioendothelioma

Hepatic epithelioid hemangioendothelioma (HEHE) is a rare tumor. Preoperative diagnosis of HEHE is difficult because it does not manifest specific symptoms or tumor markers. We report a resected case of small and solitary HEHE. The patient, a 74-year-old man, had undergone surgical resection for left renal cell carcinoma 20 years ago. During follow-up, a tumor approximately 1.3 cm in diameter was detected by computed tomography (CT) at liver segment VIII. It showed isodensity in the arterial phase, low density in the portal venous phase, and homogeneous enhancement in the late phase on CT and magnetic resonance imaging (MRI). We performed hepatic resection of the right hepatic vein drainage area. A pathological diagnosis of HEHE was made. Although small and solitary HEHE is rare, an enhancement pattern in each phase on CT and MRI, using contrast media, can yield clues for the diagnosis of HEHE

Bee products prevent VEGF-induced angiogenesis in human umbilical vein endothelial cells

<p>Abstract</p> <p>Background</p> <p>Vascular endothelial growth factor (VEGF) is a key regulator of pathogenic angiogenesis in diseases such as cancer and diabetic retinopathy. Bee products [royal jelly (RJ), bee pollen, and Chinese red propolis] from the honeybee, <it>Apis mellifera</it>, have been used as traditional health foods for centuries. The aim of this study was to investigate the anti-angiogenic effects of bee products using human umbilical vein endothelial cells (HUVECs).</p> <p>Methods</p> <p>In an <it>in vitro </it>tube formation assay, HUVECs and fibroblast cells were incubated for 14 days with VEGF and various concentrations of bee products [RJ, ethanol extract of bee pollen, ethanol extract of Chinese red propolis and its constituent, caffeic acid phenethyl ester (CAPE)]. To clarify the mechanism of <it>in vitro </it>angiogenesis, HUVEC proliferation and migration were induced by VEGF with or without various concentrations of RJ, bee pollen, Chinese red propolis, and CAPE.</p> <p>Results</p> <p>RJ, bee pollen, Chinese red propolis, and CAPE significantly suppressed VEGF-induced <it>in vitro </it>tube formation in the descending order: CAPE > Chinese red propolis >> bee pollen > RJ. RJ and Chinese red propolis suppressed both VEGF-induced HUVEC proliferation and migration. In contrast, bee pollen and CAPE suppressed only the proliferation.</p> <p>Conclusion</p> <p>Among the bee products, Chinese red propolis and CAPE in particular showed strong suppressive effects against VEGF-induced angiogenesis. These findings indicate that Chinese red propolis and CAPE may have potential as preventive and therapeutic agents against angiogenesis-related human diseases.</p
