Slow earthquakes are a recently discovered phenomenon that mainly occur updip and downdip of the seismogenic zones of great earthquakes along the subducting plate interface. The spatiotemporal activity of various slow earthquakes occurring in the Nankai subduction zone is characterized by along-strike heterogeneity and along-dip systematic changes. Various slow earthquakes are horizontally distributed at their own depths and along-strike segments can be observed with respect to this distribution downdip of the locked zone; however, slow and great earthquakes occur in the same depth range near the Nankai Trough and Japan Trench axes. The frequently observed spatiotemporal interactions between different slow earthquakes can be attributed to their sensitivity and the stress transfer of the surrounding areas. This stress transfer is expected to extend to the adjacent sections in the seismogenic zone. Therefore, precise monitoring of slow earthquakes is important for future evaluations of great earthquakes, which requires the long-term maintenance and continuous improvement of the high-quality observation networks.Although the human body appears superficially symmetrical with regard to the left-right (L-R) axis, most visceral organs are asymmetric in terms of their size, shape, or position. Such morphological asymmetries of visceral organs, which are essential for their proper function, are under the control of a genetic pathway that operates in the developing embryo. In many vertebrates including mammals, the breaking of L-R symmetry occurs at a structure known as the L-R organizer (LRO) located at the midline of the developing embryo. This symmetry breaking is followed by transfer of an active form of the signaling molecule Nodal from the LRO to the lateral plate mesoderm (LPM) on the left side, which results in asymmetric expression of Nodal (a left-side determinant) in the left LPM. Finally, L-R asymmetric morphogenesis of visceral organs is induced by Nodal-Pitx2 signaling. This review will describe our current understanding of the mechanisms that underlie the generation of L-R asymmetry in vertebrates, with a focus on mice.The identification of mutations in the epidermal growth factor receptor (EGFR) gene has revolutionized the treatment strategy for non-small cell lung cancer (NSCLC). The effectiveness of individualized treatment using EGFR tyrosine kinase inhibitors (TKIs) for EGFR-mutated NSCLC has mainly been clarified in clinical trials within Japan, and EGFR-TKI monotherapy has been established as the standard first-line treatment for EGFR-mutated NSCLC. Since then, combination regimens involving EGFR-TKI and chemotherapy or anti-angiogenic agents have been developed. Regarding combinations, the NEJ009 study conducted in Japan showed a significant prolongation of progression-free survival and overall survival compared with gefitinib alone. The NEJ009 regimen may be a reasonable option for patients with good performance status in terms of risk-benefit balance. However, further investigation is warranted to improve clinical outcomes in EGFR-mutated NSCLC.More than 90% of bladder cancer is composed of transitional cell carcinoma (TCC), being characterized by the development of multiple tumors in the entire urinary tract over time. When cystectomy is conducted, the urinary tract must be reconstructed by various procedures, which can include an orthotopic neobladder using the patient's own intestine formed into a spherical shape anastomosed to the urethra. Using this procedure, patients can void urine from their own urethra even after cystectomy. The incidence of subsequent urethral cancer arising after cystectomy is known to be relatively high; however, if patients with a high risk of urethral recurrence are appropriately excluded, a neobladder can be safely provided for patients. Orthotopic neobladder use is reviewed from an oncological viewpoint and the patient's quality of life after cystectomy for bladder cancer.Today, the silicon carbide (SiC) semiconductor is becoming the front runner in advanced power electronic devices. This material has been considered to be useful for abrasive powder, refractory bricks as well as ceramic varistors. Big changes have occurred owing to the author's inspirational idea in 1968 to "make transistors from unusual material". The current paper starts by describing the history of SiC research involving fundamental studies by the author's group unique epitaxial crystal growth techniques, the physical characterization of grown layers and processes for device fabrication. Trials for fabricating SiC power devices and their characteristics conducted until 2004 are precisely described. Recent progress in SiC crystal growth and peripheral techniques for SiC power devices are introduced. Finally, the present progress concerning SiC power devices is introduced together with the implementation of those devices in society.A 38-year-old man presented with primary position upbeat nystagmus accompanied by peripheral neuropathy. The serum vitamin B12 level was low along with high plasma homocysteine level, indicating vitamin B12 deficiency. Cyanocobalamin supplementation showed partial clinical and electrophysiological improvement. Although brain magnetic resonance imaging did not show any abnormal intensity lesions, the electrophysiological findings suggested that a pontomedullary medial lesion was responsible for the upbeat nystagmus. To our knowledge, this is the first case of upbeat nystagmus with low serum vitamin B12. Physicians need to recognize the possibility of vitamin B12 deficiency as a cause of upbeat nystagmus.Although cardiovascular involvement is a well-known complication correlated with a poor prognosis in patients with systemic sclerosis, there are few reports on valvular heart disease. Forty patients with systemic sclerosis were retrospectively analyzed. Valvular heart disease was found in six patients, five of whom had severe tri-leaflet aortic stenosis. Three of these 5 patients were ≤71 years old. Two frail elderly patients who underwent transcatheter aortic valve replacement died within two years. Premature-onset aortic stenosis is not uncommon in patients with systemic sclerosis. When considering mechanical intervention, the evaluation of frailty is important.We herein report the histological findings of a patient who had progressed to persistent cardiac arrest for 25 days due to lymphocytic fulminant myocarditis despite mechanical circulatory support (MCS). There were few residual cardiomyocytes, and extensive replacement fibrosis was present. Therefore, improvement of the cardiac function for this patient was considered improbable. Further research is warranted to improve predictions for the recovery of the cardiac function and optimize MCS strategies for patients with fulminant myocarditis.Objective Acetylcholine (ACh) use in patients with bronchial asthma (BA) is contraindicated. We examined the clinical usefulness and safety of ACh spasm provocation tests in rest angina patients with BA. Patients The study subjects were 495 rest angina patients (mean age 64.4±10.9 years old, male 81.0%). Organic stenosis was found in 69 patients (13.9%). Methods We investigated 495 rest angina patients who underwent ACh spasm provocation tests. ACh was injected in incremental doses of 20/50/100/200 μg into the left coronary artery and 20/50/80 μg into the right coronary artery. Provoked positive spasm was defined as transient ≥90% luminal narrowing and usual chest pain or ischemic electrocardiogram changes. Degrasyn Results Among 495 rest angina patients, 13 (2.6%) were complicated with BA. Eleven patients with BA were controlled under medications, and two patients had a history of medication for BA. The clinical characteristics were not markedly different between rest angina patients with and without BA. The rate of multi-vessel spasm was markedly higher in patients with BA than that in those without BA. No complications during ACh spasm provocation tests were recognized in rest angina patients with BA, whereas major complications in those without BA were observed in eight patients including two ventricular fibrillations, three non-sustained ventricular tachycardias, and three shocks. We were able to perform all 495 ACh spasm provocation tests without any irreversible complications, while electrical defibrillation was necessary for 2 patients without BA. Conclusion We were able to perform ACh spasm provocation tests in rest angina patients with BA irrespective of the off-label use of ACh.Objective The burden of death from pneumonia is expected to increase with the aging of the population, as has been observed in Japan. Depressive tendency, a common psychosocial sign, may be a risk factor for pneumonia due to its possible association with some immune dysfunction. This study aimed to clarify the association between depressive tendency and the risk of death from pneumonia. Methods A population-based cohort that consisted of 75,174 Japanese men and women was followed for a median of 19.1 years. Four psychological and behavioral symptoms (depressive symptoms) were used to evaluate depressive tendency. Results A total of 1,329 deaths from pneumonia were observed. Depressive symptoms were positively and dose-dependently associated with the risk of death from pneumonia (p less then 0.001 for trend), and subjects with ≥2 depressive symptoms showed a significantly elevated risk compared to those without any symptoms [multivariable hazard ratio (HR), 1.66; 95% confidence interval (CI), 1.39-1.99]. This association was not significantly affected by sex or age at baseline. The elevated risk was still significant even when subjects were limited to those without any medical histories. The excess risk was observed not only for death occurring within the first 10 years of follow-up (multivariable HR, 2.05; 95% CI, 1.51-2.78) but also for that occurring in the longer follow-up period (multivariable HR, 1.48; 95% CI, 1.18-1.85). Conclusion Depressive tendency may be a risk factor for death from pneumonia. Further studies using a more reliable tool for the evaluation of depressive state are necessary to confirm this relationship.Molecular-targeted drugs (MTDs), such as epidermal growth factor receptor tyrosine kinase inhibitors (EGFR-TKIs) and anaplastic lymphoma kinase inhibitors, are used to treat non-small-cell lung cancer (NSCLC). The incidence of rash caused by EGFR-TKIs and discontinuation of MTDs because of rash are issues. Rapid desensitization therapy (RDT) was performed in five patients who developed severe rash after introduction of MTDs and was successful in four, all of whom showed no rash relapse. RDT may thus be useful for treating rash in patients receiving MTDs for NSCLC.We herein report a 76-year-old man who developed irritability and forgetfulness 5 months after the introduction of atezolizumab for the treatment of small cell lung cancer (SCLC). Brain magnetic resonance imaging showed lesions of the striatum, and an investigation of the serum revealed a high titer of anti-CRMP5 antibody. After stopping atezolizumab and starting steroid pulse therapy, these clinical features improved. Given these findings, it is considered that CRMP5-assciated striatal encephalitis was induced by atezolizumab in this case with SCLC.
