AIM: To compare the clinical efficacy of the secondgeneration H2 RA lafutidine with that of lansoprazole in Japanese patients with mild gastroesophageal reflux disease(GERD). METHODS: Patients with symptoms of GERD and a diagnosis of grade A reflux esophagitis(according to the Los Angeles classification) were randomized to receive lafutidine(10 mg, twice daily) or lansoprazole(30 mg, once daily) for an initial 8 wk, followed by maintenance treatment comprising half-doses of the assigned drug for 24 wk. The primary endpoint was the frequency and severity of heartburn during initial and maintenance treatment. The secondary endpoints were the sum score of questions 2 and 3 in the Gastrointestinal Symptom Rating Scale(GSRS), and the satisfaction ***: Between April 2012 and March 2013, a total of 53 patients were enrolled, of whom 24 and 29 received lafutidine and lansoprazole, respectively. After 8 wk, the frequency and severity of heartburn was significantly reduced in both groups. However, lafutidine was significantly inferior to lansoprazole with regard to the severity of heartburn during initial and maintenance treatment(P = 0.016). The sum score of questions 2 and 3 in the GSRS, and satisfaction scores were also significantly worse in the lafutidine group than the lansoprazole group(P = 0.0068 and P = 0.0048, respectively).CONCLUSION: The clinical efficacy of lafutidine was inferior to that of lansoprazole, even in Japanese patients with mild GERD.

A predual of a predual of B_σ and its applications to commutators

引用

Science China Mathematics 2018年第8期61卷 1437-1472页

作者： Yoshihiro Sawano hiroko Yoshida Department of Mathematics and Information Science Tokyo Metropolitan University

A predual of B_σ-spaces is investigated. A predual of a predual of B_σ-spaces is also investigated,which can be used to investigate the boundedness property of the commutators. The relation between Herz spaces and local Morrey spaces is discussed. As an application of the duality results, one obtains the boundedness of the singular integral operators, the Hardy-Littlewood maximal operators and the fractional integral operators, as well as the commutators generated by the bounded mean oscillation(BMO) and the singular integral *** is new in this paper is that we do not have to depend on the specific structure of the operators. The results on the boundedness of operators are formulated in terms of B_σ-spaces and B_σ-spaces together with the detailed comparison of the ones in Herz spaces and local Morrey spaces. Another application is the nonsmooth atomic decomposition adapted to B_σ-spaces.

Tumor biology in estrogen receptor-positive,human epidermal growth factor receptor type 2-negative breast cancer:Mind the menopausal status

引用

World Journal of Clinical Oncology 2015年第6期6卷 220-224页

作者： hiroko Yamashita Breast Surgery Hokkaido University Hospital

Breast cancer is not one disease,but can be categorized into four major molecular subtypes according to hormone receptor [estrogen receptor(ER) and progesterone receptor(Pg R)] and human epidermal growth factor receptor type 2(HER2) expression status. Ki67 labeling index and/or multigene assays are used to classify ERpositive,HER2-negative breast cancer into luminal A and luminal B(HER2-negative) subtypes. To date,most studies analyzing predictive or prognostic factors in ER-positive breast cancer have been performed in postmenopausal women,mainly using patients and samples in adjuvant aromatase inhibitor trials. In contrast,even the clinical roles of Pg R and Ki67 have been little analyzed so far in premenopausal women. Pg R is one of the estrogen-responsive genes,and it has been reported that plasma estradiol levels are related to expression levels of estrogen-responsive genes including PGR in ER-positive breast cancer. In this article,biological differences,especially differences in expression of Pg R and Ki67 in ER-positive breast cancer between pre- and postmenopausal women are discussed. Clinical roles of Pg R and Ki67 in ER-positive breast cancer differ between pre- and postmenopausal women. We suggest that the mechanisms of development and estrogen-dependent growth of ER-positive breast cancer might differ according to menopausal status.

Gamete Dialogs in Green Lineages

Gamete fusion is a core process of sexual reproduction and, in both plants and animals, different sex gametes fuse within species. Although most of the molecular factors involved in gamete interaction are still unknown in various sex-possessing eukaryotes, reports of such factors in algae and land plants have been increasing in the past decade. In particular, knowledge of gamete interaction in flowering plants and green algae has increased since the identification of the conserved gamete fusion factor GENERATIVE CELL SPECIFIC 1/HAPLESS 2 （GCS1/HAP2）. GCSl was first identified as a pollen generative cell-specific transmembrane protein in the lily （Lilium Iongiflorum）, and was then shown to function not only in flowering plant gamete fusion but also in various eukaryotes, including unicellular protists and metazoans. In addition, although initially restricted to Chlamydomonas, knowledge of gamete attachment in flowering plants was also acquired. This review focuses on recent progress in the study of gamete interaction in volvocine green algae and flowering plants and discusses conserved mechanisms of gamete recognition, attachment, and fusion leading to zygote formation.

SLC6A4 （solute carrier family 6, member 4） gene encodes a serotonin transporter （5-hydroxytryptamine transporter, HTT）, which transports synaptic serotonin into presynaptic terminal. SLC6A4 is known to be the target of antidepressants such as selective serotonin reuptake inhibitors （SSRIs）. Inhibition of HTT increases synaptic serotonin concentration and thereby exerts antidepressant efficacy. A large number of genetic studies suggest the contribution of genetic variations of SLC6A4 to various psychiatric disorders. The most studied genetic variation, HTT-linked polymorphic region （HTTLPR）,

Intermittent compressive force induces cell cycling and reduces apoptosis in embryoid bodies of mouse induced pluripotent stem cells

引用

International Journal of Oral Science 2022年第1期14卷 40-50页

In vitro manipulation of induced pluripotent stem cells(iPSCs) by environmental factors is of great interest for three-dimensional(3D) tissue/organ induction. The effects of mechanical force depend on many factors, including force and cell type. However,information on such effects in i PSCs is lacking. The aim of this study was to identify a molecular mechanism in i PSCs responding to intermittent compressive force(ICF) by analyzing the global gene expression profile. Embryoid bodies of mouse i PSCs, attached on a tissue culture plate in 3D form, were subjected to ICF in serum-free culture medium for 24 h. Gene ontology analyses for RNA sequencing data demonstrated that genes differentially regulated by ICF were mainly associated with metabolic processes,membrane and protein binding. Topology-based analysis demonstrated that ICF induced genes in cell cycle categories and downregulated genes associated with metabolic processes. The Kyoto Encyclopedia of Genes and Genomes database revealed differentially regulated genes related to the p53 signaling pathway and cell cycle. q PCR analysis demonstrated significant upregulation of Ccnd1, Cdk6 and Ccng1. Flow cytometry showed that ICF induced cell cycle and proliferation, while reducing the number of apoptotic cells. ICF also upregulated transforming growth factor β1(Tgfb1) at both m RNA and protein levels, and pretreatment with a TGF-β inhibitor(SB431542) prior to ICF abolished ICF-induced Ccnd1 and Cdk6 expression. Taken together,these findings show that TGF-β signaling in i PSCs enhances proliferation and decreases apoptosis in response to ICF, that could give rise to an efficient protocol to manipulate i PSCs for organoid fabrication.
