The Compositional Process behind The Song of Trees for Solo Marimba by Keiko Abe

Solo marimba repertoire has grown significantly since the 1970s. As a result of this expansion, there is no doubt that the marimba is regarded as a legitimate solo instrument. One of the pioneers of the solo marimba is Keiko Abe. She developed solo literature and performance skills, and improved the reputation of the marimba as a solo instrument. She was also directly responsible for improvements to the design of the instrument itself. Ms. Abe has been a well-known marimba player, educator, and composer for almost four decades. Her music, life, and achievements are featured in many international media such as Percussive Arts Notes, BBC Music, Concertgebouw Brugge, Ongaku No Tomo and so on. I am a native of Japan, currently working in the United States as a percussionist. In August 2017, I traveled to Tokyo, Japan with the goal of contributing to the general understanding of Ms. Abe\u27s music. I spent several hours in Keiko Abe\u27s home studio. Ms. Abe gave me a private lesson, and answered questions regarding her music and life. The purpose of this lecture recital and reserch document is to prepare and perform a piece entitled The Song of Trees and four other compositions by Ms. Abe. The paper will briefly describe Keiko Abe\u27s biography, continuing into the reserch of The Song of Trees. The reserch includes the study of connetions between The Song of Trees and some of Ms. Abe\u27s previous compositions, representing different points of her compositioal career. The pieces to be performed and discussed chosen at Ms. Abe\u27s suggestion include: Michi, Memories of the Seashore, Wind across Mountains, Michi Paraphrase, and The Song of Trees. The latter part of the research will be a performance analysis of The Song of Trees, informed by the interview and private lesson with Ms. Abe

Impact of COVID-19 on cardiovascular testing in the United States versus the rest of the world

Objectives: This study sought to quantify and compare the decline in volumes of cardiovascular procedures between the United States and non-US institutions during the early phase of the coronavirus disease-2019 (COVID-19) pandemic. Background: The COVID-19 pandemic has disrupted the care of many non-COVID-19 illnesses. Reductions in diagnostic cardiovascular testing around the world have led to concerns over the implications of reduced testing for cardiovascular disease (CVD) morbidity and mortality. Methods: Data were submitted to the INCAPS-COVID (International Atomic Energy Agency Non-Invasive Cardiology Protocols Study of COVID-19), a multinational registry comprising 909 institutions in 108 countries (including 155 facilities in 40 U.S. states), assessing the impact of the COVID-19 pandemic on volumes of diagnostic cardiovascular procedures. Data were obtained for April 2020 and compared with volumes of baseline procedures from March 2019. We compared laboratory characteristics, practices, and procedure volumes between U.S. and non-U.S. facilities and between U.S. geographic regions and identified factors associated with volume reduction in the United States. Results: Reductions in the volumes of procedures in the United States were similar to those in non-U.S. facilities (68% vs. 63%, respectively; p = 0.237), although U.S. facilities reported greater reductions in invasive coronary angiography (69% vs. 53%, respectively; p < 0.001). Significantly more U.S. facilities reported increased use of telehealth and patient screening measures than non-U.S. facilities, such as temperature checks, symptom screenings, and COVID-19 testing. Reductions in volumes of procedures differed between U.S. regions, with larger declines observed in the Northeast (76%) and Midwest (74%) than in the South (62%) and West (44%). Prevalence of COVID-19, staff redeployments, outpatient centers, and urban centers were associated with greater reductions in volume in U.S. facilities in a multivariable analysis. Conclusions: We observed marked reductions in U.S. cardiovascular testing in the early phase of the pandemic and significant variability between U.S. regions. The association between reductions of volumes and COVID-19 prevalence in the United States highlighted the need for proactive efforts to maintain access to cardiovascular testing in areas most affected by outbreaks of COVID-19 infection

Patient-Derived Exosomes as siRNA Carriers in Ovarian Cancer Treatment

RNA interference is a powerful gene-silencing tool with potential clinical applications. However, its therapeutic use is challenging because suitable carriers are unavailable. Exosomes are stable small endogenous vesicles that can transport functional molecules to target cells, making them ideal small interfering RNA (siRNA) carriers. Herein, we elucidated the therapeutic potential of patient-derived exosomes as an siRNA carrier for ovarian cancer (OC) treatment. The exosomes were extracted from the culture medium of primary fibroblasts collected from the omentum of patients with OC during surgery. MET proto-oncogene, receptor tyrosine kinase (MET) was selected for gene silencing, c-Met siRNAs were synthesized and loaded into the exosomes (Met-siExosomes) via electroporation, and the treatment effect of the Met-siExosomes was assessed in vitro and in vivo. The Met-siExosomes downregulated the c-Met protein levels and inhibited OC cell proliferation, migration, and invasion. In xenograft experiments using SKOV3-13 and ES-2 cells, Met-siExosomes were selectively extracted from peritoneally disseminated tumors. Intraperitoneal treatment suppressed the c-Met downstream targets in cancer cells and prolonged mouse survival. The synthesized siRNAs were successfully and selectively delivered via the exosomes to intraperitoneally disseminated tumors. As patients with OC routinely undergo omentectomy and abundant fibroblasts can be easily collected from the omentum, patient-derived exosomes may represent a promising therapeutic siRNA carrier to treat OC

Effect of Japanese Kampo Medicine Therapy for Menopausal Symptoms after Treatment of Gynecological Malignancy

Loss of ovarian function by the treatment for gynecological malignancy results in a drastic decrease of estrogen causing physical and mental symptoms. The purpose of this study is to evaluate the effect of Japanese Kampo Kamikihito (KKT) and Kamishoyosan (KSS) on menopausal symptoms in gynecological cancer patients. Patients who had menopausal symptoms after gynecologic malignancy treatment were enrolled and randomly divided into a KKT or a KSS group. Kupperman Menopausal Index (KI) questionnaires were obtained before tumor treatment, at baseline, and at 4 and 8 weeks. Changes in KI scores and severity of each symptom were evaluated. A total of 33 patients were enrolled: 18 in the KKT group and 15 in the KSS group. The KI scores significantly decreased at 4 and 8 weeks compared with baseline in both groups. Although no significant difference was found in change in KI scores between the KKT and KSS groups, efficacy showed some differences. Both KKT and KSS were effective for insomnia, vertigo, and palpitation. KSS was also effective for vasomotor symptoms and arthralgia/myalgia. In conclusion, both KKT and KSS were effective for menopausal symptoms in patients after gynecological tumor treatment. Tailor-made Kampo therapy may contribute to improve patients’ physical and mental symptoms

Preclinical Investigations of PM01183 (Lurbinectedin) as a Single Agent or in Combination with Other Anticancer Agents for Clear Cell Carcinoma of the Ovary.

OBJECTIVE:The objective of this study was to evaluate the antitumor effects of lurbinectedin as a single agent or in combination with existing anticancer agents for clear cell carcinoma (CCC) of the ovary, which is regarded as an aggressive, chemoresistant, histological subtype. METHODS:Using human ovarian CCC cell lines, the antitumor effects of lurbinectedin, SN-38, doxorubicin, cisplatin, and paclitaxel as single agents were assessed using the MTS assay. Then, the antitumor effects of combination therapies involving lurbinectedin and 1 of the other 4 agents were evaluated using isobologram analysis to examine whether these combinations displayed synergistic effects. The antitumor activity of each treatment was also examined using cisplatin-resistant and paclitaxel-resistant CCC sublines. Finally, we determined the effects of mTORC1 inhibition on the antitumor activity of lurbinectedin-based chemotherapy. RESULTS:Lurbinectedin exhibited significant antitumor activity toward chemosensitive and chemoresistant CCC cells in vitro. An examination of mouse CCC cell xenografts revealed that lurbinectedin significantly inhibits tumor growth. Among the tested combinations, lurbinectedin plus SN-38 resulted in a significant synergistic effect. This combination also had strong synergistic effects on both the cisplatin-resistant and paclitaxel-resistant CCC cell lines. Everolimus significantly enhanced the antitumor activity of lurbinectedin-based chemotherapies. CONCLUSIONS:Lurbinectedin, a new agent that targets active transcription, exhibits antitumor activity in CCC when used as a single agent and has synergistic antitumor effects when combined with irinotecan. Our results indicate that lurbinectedin is a promising agent for treating ovarian CCC, both as a first-line treatment and as a salvage treatment for recurrent lesions that develop after platinum-based or paclitaxel treatment
