タイトル: Relative Risk Aversion and Business Fluctuations著者: Hashimoto, Ken-ichi; Im, Ryonghun; Kunieda, Takuma; Shibata, Akihisa抄録: By applying a simple dynamic general equilibrium model without exogenous shocks inhabited by infinitely lived capitalists and workers, we show that a higher degree of relative risk aversion can destabilize an economy. In traditional real business cycle (RBC) theory, a higher degree of relative risk aversion dampens the amplitude of the consumption fluctuations caused by exogenous shocks through consumption smoothing. However, a higher degree of relative risk aversion combined with a high degree of elasticity of the marginal product of capital can also lead to the emergence of a nonlinear mechanism that causes endogenous business fluctuations. The nontrivial steady state loses stability due to the higher degree of relative risk aversion; thus, endogenous business fluctuations can occur. This result suggests that for a deeper understanding of b ...

タイトル: Colorectal anastomotic leakage after conversion surgery for advanced endometrial cancer treated with lenvatinib plus pembrolizumab: a case report著者: Yamamura, Akitoshi; Hamanishi, Junzo; Yamanoi, Koji; Sunada, Masumi; Taki, Mana; Mizuno, Rin; Okada, Yukiko; Murakami, Ryusuke; Aisu, Yuki; Maekawa, Hisatsugu; Yamaguchi, Ken; Mandai, Masaki抄録: The combination therapy of lenvatinib plus pembrolizumab (LP) is increasingly recognized as an important second-line regimen for advanced or recurrent endometrial cancer (EC). However, the safety and efficacy of conversion surgery with low anterior rectal resection for unresectable EC following LP therapy is unknown. A 37-year-old woman was referred with unresectable EC with pleural fluid, peritoneal dissemination, and ascites. After the failure of first-line platinum-based chemotherapy, she was administered LP as second-line treatment. After 10 treatment cycles, uterine and peritoneal tumors significantly reduced in size, exce ...

タイトル: Neural substrates underlying distinct dual cognitive syndromes in Parkinson's disease著者: Yoshimura, Kenji; Shima, Atsushi; Kambe, Daisuke; Furukawa, Koji; Nishida, Akira; Wada, Ikko; Sakato, Yusuke; Sakamaki-Tsukita, Haruhi; Terada, Yuta; Yamakado, Hodaka; Taruno, Yosuke; Nakanishi, Etsuro; Sawamura, Masanori; Fujimoto, Koji; Fushimi, Yasutaka; Okada, Tomohisa; Nakamoto, Yuji; Hanakawa, Takashi; Takahashi, Ryosuke; Sawamoto, Nobukatsu抄録: Background: A dual-syndrome hypothesis, which states the cognitive impairments in Parkinson's disease (PD) are attributable to frontostriatal dopaminergic dysregulation and cortical disturbance-each associated with attention/executive and memory/visuospatial dysfunction, respectively-has been widely accepted. This multisystem contribution also underlies highly heterogeneous progression rate to dementia. Methods: Nondemented PD patients who underwent [¹²³I]N-ω-fluoropropyl-2β-carbomethoxy-3β-(4-iodophenyl) nortropane ([¹²³ ...

タイトル: Adverse effects of graft congestion and ameliorative effects of hepatocyte growth factor after liver transplantation in rats著者: Aoki, Hikaru; Ito, Takashi; Hirata, Masaaki; Okumura, Shinya; Masano, Yuki; Ogawa, Eri; Haga, Hironori; Hatano, Etsuro抄録: Living donor liver transplantation (LT) and deceased donor split-LT often result in congestion within liver grafts. The regenerative process and function of congested areas, especially graft congestion associated with LT, are not well understood. Therefore, we created new rat models with congested areas in partially resected livers and orthotopically transplanted these livers into syngeneic rats to observe liver regeneration and function in congested areas. This study aimed to compare liver regeneration and the function of congested areas after liver resection and LT, and to explore a new approach to ameliorate the adverse effects of graft congestion. Although the congested areas after liver resection regenerated norma ...
