Malignant bowel obstruction (MBO), an occasional complication in patients with advanced urological cancer, causes gastrointestinal symptoms such as nausea and vomiting leading to suffering which severely impairs quality of life (QOL). Drug therapy, especially octreotide, a synthetic analog of somatostatin, is reportedly effective in controlling the symptoms of MBO. In the present study, we administered octreotide to urological cancer patients with MBO and evaluated the improvement of subjective symptoms, oral intake, and nasogastric intubation. Fourteen terminally ill urological cancer patients suffering with MBO were included (age range 55-92, 10 male, 4 female). Octreotide was administered at $300{\mu}g/day$ to those patients subcutaneously as a continuous injection. Significant improvements in subjective symptoms were observed in thirteen patients (92.8%), and ten patients (71.4%) were able to resume oral intake. Four patients required nasogastric drainage before the administration of octreotide, but nasogastric intubation was discontinued in all these cases after the use of octreotide. Early initiation of octreotide resulted in better improvement of MBO symptoms, and no adverse event was observed in any of the patients. These results revealed that $300{\mu}g/day$ dose of octreotide is safe and effective for managing gastrointestinal symptoms of terminally ill urological cancer patients with MBO. We also recommend starting the treatment with ocreotide as soon as MBO is diagnosed.
NPI licensing and the logic of the syntax-semantics interface
Yusuke Kubota,Robert Levine 경희대학교 언어정보연구소 2021 언어연구 Vol.38 No.2
In this paper, we propose an explicit syntax-semantics interface of NPI licensing in Hybrid TLG. Hybrid TLG is a version of categorial grammar that inherits properties of both lexicalist and derivational variants of generative grammar, and it has been shown in our previous research (summarized in Kubota and Levine 2020) that it offers elegant analyses for a number of complex phenomena at the interface of syntax and semantics (especially in the domains of coordination and ellipsis) that turn out to be highly problematic for other grammatical theories. In the present paper, we extend our work to NPI licensing and report on some initial results suggesting that the flexible and systematic architecture of Hybrid TLG turns out to be successful in this domain too. Specifically, our approach captures interactions between NPI licensing (or polarity sensitivity) and other complex phenomena at the syntax-semantics interface including the scopal properties of modal auxiliaries, Gapping, and VP fronting.
The Infrastructure of Public Opinion Research in Japan
Kubota, Yuichi Center for Asian Public Opinion ResearchCollaborat 2013 Asian journal for public opinion research Vol.1 No.1
This article introduces the infrastructure of public opinion research in Japan by reviewing the development of polling organizations and the current situation of social surveys. In Japan, the polling infrastructure developed through the direction and encouragement of the U.S. occupation authorities. In the early 1969s, however, survey researchers began to conduct their own original polls in not only domestic but also cross-national contexts. An exploration of recent survey trends reveals that polling organizations tended to conduct more surveys during summer, in the mid-range of sample size (1,000-2,999), based on random sampling (response rates of 40-50%), and through the mail between April 2011 and March 2012. The media was the most active polling sector.
Cooperative interaction of Angiopoietin-like proteins 1 and 2 in zebrafish vascular development.

<P>Angiopoietin-like protein (Angptl) 1 and Angptl2, which are considered orphan ligands, are highly homologous, particularly in the fibrinogen-like domain containing the putative receptor binding site. This similarity suggests potentially cooperative functions between the two proteins. In this report, the function of Angptl1 and Angptl2 is analyzed by using morpholino antisense technology in zebrafish. Knockdown of both Angptl1 and Angptl2 produced severe vascular defects due to increased apoptosis of endothelial cells at the sprouting stage. In vitro studies showed that Angptl1 and Angptl2 have antiapoptotic activities through the phosphatidylinositol 3-kinase/Akt pathway, and coinjection of constitutively active Akt/protein kinase B mRNA rescued impaired vascular development seen in double knockdown embryos. These results provide a physiological demonstration of the cooperative interaction of Angptl1 and Angptl2 in endothelial cells through phosphatidylinositol 3-kinase/Akt mediated antiapoptotic activities.</P>

<▼1><P>Photoperiod is one of the most reliable environmental cues for plants to regulate flowering timing. In <I>Arabidopsis thaliana</I>, CONSTANS (CO) transcription factor plays a central role in regulating photoperiodic flowering. In contrast to posttranslational regulation of CO protein, still little was known about <I>CO</I> transcriptional regulation. Here we show that the CINCINNATA (CIN) clade of class II TEOSINTE BRANCHED 1/ CYCLOIDEA/ PROLIFERATING CELL NUCLEAR ANTIGEN FACTOR (TCP) proteins act as <I>CO</I> activators. Our yeast one-hybrid analysis revealed that class II CIN-TCPs, including TCP4, bind to the <I>CO</I> promoter. TCP4 induces <I>CO</I> expression around dusk by directly associating with the <I>CO</I> promoter <I>in vivo</I>. In addition, TCP4 binds to another flowering regulator, GIGANTEA (GI), in the nucleus, and induces <I>CO</I> expression in a <I>GI</I>-dependent manner. The physical association of TCP4 with the <I>CO</I> promoter was reduced in the <I>gi</I> mutant, suggesting that GI may enhance the DNA-binding ability of TCP4. Our tandem affinity purification coupled with mass spectrometry (TAP-MS) analysis identified all class II CIN-TCPs as the components of the <I>in vivo</I> TCP4 complex, and the <I>gi</I> mutant did not alter the composition of the TCP4 complex. Taken together, our results demonstrate a novel function of CIN-TCPs as photoperiodic flowering regulators, which may contribute to coordinating plant development with flowering regulation.</P></▼1><▼2><P><B>Author summary</B></P><P>For plant adaptation to seasonal environments, a crucial developmental event is flowering, as proper timing of flowering affects reproductive success. Although plants monitor various environmental parameters to optimize this timing, photoperiod information is important for plants to regulate seasonal flowering time, because changes in photoperiod occur in a predictable manner throughout the year. The model plant <I>Arabidopsis thaliana</I> responds to photoperiodic changes and flowers under long-day conditions. Based on genetic analyses using mutants defective in the photoperiodic flowering response, we learned that the transcription factor referred to as CONSTANS (CO) plays a central role in regulating the timing of flowering by directly controlling the expression of florigen (flowering-inducing substrate) gene. Long-day afternoon expression of <I>CO</I> is critical for this regulation; however, we had limited knowledge of <I>CO</I> transcriptional regulation. Here we identified that a group of plant-specific transcription factors belonging to the <I>TCP</I> gene family function as novel <I>CO</I> transcriptional activators. We demonstrated that TCP transcription factors regulate <I>CO</I> transcription together with known regulators of <I>CO</I>. Our results imply that plants utilize multiple transcription factors to precisely coordinate the expression of the key regulator gene, <I>CO</I>, which will directly affect flowering time.</P></▼2>
First Finding of a Bivalve-Inhabiting Hydrozoan (Cnidaria, Hydrozoa) from Korea
Kubota, Shin,Lee, Jimin,Chang, Cheon Young The Korean Society of Systematic Zoology 2019 Animal Systematics, Evolution and Diversity Vol.35 No.2
Eutima japonica Uchida, 1925, a bivalve-inhabiting hydrozoan was collected for the first time in Korea, associating with Mytilus galloprovincialis. The morphology of male medusae of this hydrozoan is clarified by culture and described as well as other developmental stages. As the present material from Korea is in good accord with that of the northern Japanese form of E. japonica, so the geographical distribution of the northern form of this species is widened, Japan, China and Korea. Green fluorescent protein distribution pattern of this medusa is also described and compared with that of the most related species Eutima sapinhoa Narchi and Hebling, 1975.
