Professionals On Corporate Boards In Japan: How Do They Affect The Bottom Line?

Working paper on INCAS blog : https://incas.hypotheses.org/Licensed professionals, such as accountants and lawyers, play a variety of roles when they sit on corporate boards. This paper sheds light on what role professional-directors play under what circumstances, and its consequences for corporate performance. We develop a theory that links professional roles (as cops, counsel, or entrepreneur) to antecedents in terms of external environment (notably the extent of government regulation) and to consequences for firm performance (profitability, corporate valuation, and stock return volatility). Using a data of all publicly quoted companies in Japan during 2004-2015, we demonstrate that the presence of professional-directors increases profitability and corporate valuation in all sectors, and that they contribute to higher stock return volatility in regulated and lower volatility in less regulated industries. The differential impacts of professional roles on firm performance – by acting as ‘entrepreneur’ in regulated industries and as ‘cops’ in non-regulated industries – have implications for board composition and board effectiveness. We provide discussion of the implications in the context of corporate governance reforms in Japan

High SDF-1 Expression in HIV-1 Carriers Does Not Correlate with CD8+T-Cell-Mediated Suppression of Viral Replication

AbstractStromal cell-derived factor 1 (SDF-1) inhibits T-cell tropic (T-tropic) HIV-1 infectionin vitro. In this study, we examined the regulatory role of SDF-1 on HIV-1 replication in peripheral blood mononuclear cells (PBMC) of HIV-infected individuals. We found that the amount of SDF-1 mRNA in freshly isolated PBMC of HIV-1 carriers was higher than in healthy donors. Moreover, PBMC from some asymptomatic carriers (ACs) exhibited high levels of SDF-1 mRNA expression. The level of SDF-1 expression in PBMC did not correlate with the magnitude of CD8+T cell-mediated suppression of HIV-1 among ACs. SDF-1 inhibited HIV-1 replication at the viral entry step, whereas a single-cycle HIV-1 infection system showed that the major part of the CD8+T-cell-mediated suppression occurs after intracellular penetration of the virus. Our results suggest that SDF-1 acts as a suppressor of virus replication in a CD8+T-cell-independent mechanism in HIV-infected individuals

Interfamily Transfer of Dual NB-LRR Genes Confers Resistance to Multiple Pathogens

A major class of disease resistance (R) genes which encode nucleotide binding and leucine rich repeat (NB-LRR) proteins have been used in traditional breeding programs for crop protection. However, it has been difficult to functionally transfer NB-LRR-type R genes in taxonomically distinct families. Here we demonstrate that a pair of Arabidopsis (Brassicaceae) NB-LRR-type R genes, RPS4 and RRS1, properly function in two other Brassicaceae, Brassica rapa and Brassica napus, but also in two Solanaceae, Nicotiana benthamiana and tomato (Solanum lycopersicum). The solanaceous plants transformed with RPS4/RRS1 confer bacterial effector-specific immunity responses. Furthermore, RPS4 and RRS1, which confer resistance to a fungal pathogen Colletotrichum higginsianum in Brassicaceae, also protect against Colletotrichum orbiculare in cucumber (Cucurbitaceae). Importantly, RPS4/RRS1 transgenic plants show no autoimmune phenotypes, indicating that the NB-LRR proteins are tightly regulated. The successful transfer of two R genes at the family level implies that the downstream components of R genes are highly conserved. The functional interfamily transfer of R genes can be a powerful strategy for providing resistance to a broad range of pathogens

防災の視点を組み込んだ歳時記型郷土トランプの制作とその活用による住教育

　It is important to learn regional characteristics of the living place for maintaining our living environment properly.　There are several educational tools to understand regional characteristics.　Making indigenous playing card is one of the good methods for learning regional characteristics. 　The purpose of this paper is to show the process to create indigenous playing card based on year-round event including awareness of natural disaster.　It is a collaborative integrated study with school children and university students. 　We organized workshop in Nanmoku village, Gunma prefecture.　The village is located with the border of the prefecture and surrounded by mountains.　They live close to the nature, sometimes, they faced natural disaster such as heavy snow and landslide caused by the typhoon.　We made the creative Nanmoku village playing card representation of the highly unique aspect of Nanmoku village having a perspective of disaster education.　Then we show effectiveness of living environment education by using indigenous playing card. 　Educational technique making indigenous playing card brings a lot of incentive, recognition and attachment to their living environment through various communications.　It has exciting prospect of active learning for living environment and integrated study

Optimizing the timing of 3.6 mg Pegfilgrastim Administration for Dose-Dense Chemotherapy in Japanese Patients with Breast Cancer

Perioperative dose-dense chemotherapy (DDCT) with pegfilgrastim (Peg) prophylaxis is a standard treatment for high-risk breast cancer. We explored the optimal timing of administration of 3.6 mg Peg, the dose approved in Japan. In the phase II feasibility study of DDCT (adriamycin+cyclophosphamide or epirubicin+cyclophosphamide followed by paclitaxel) for breast cancer, we investigated the feasibility, safety, neutrophil transition, and optimal timing of Peg treatment by administering Peg at days 2, 3, and 4 post-chemotherapy (P2, P3, and P4 groups, respectively). Among the 52 women enrolled, 13 were aged > 60 years. The anthracycline sequence was administered to P2 (n=33), P3 (n=5), and P4 (n=14) patients, and the taxane sequence to P2 (n=38) and P3 (n=6) patients. Both sequences showed no interaction between Peg administration timing and treatment discontinuation, treatment delay, or dose reduction. However, the relative dose intensity (RDI) was significantly different among the groups. The neutrophil count transition differed significantly among the groups receiving the anthracycline sequence. However, the neutrophil count remained in the appropriate range for both sequences in the P2 group. The timing of Peg administration did not substantially affect the feasibility or safety of DDCT. Postoperative day 2 might be the optimal timing for DDCT

Homozygosity has long been associated with rare, often devastating, Mendelian disorders1 and Darwin was one of the first to recognise that inbreeding reduces evolutionary fitness2. However, the effect of the more distant parental relatedness common in modern human populations is less well understood. Genomic data now allow us to investigate the effects of homozygosity on traits of public health importance by observing contiguous homozygous segments (runs of homozygosity, ROH), which are inferred to be homozygous along their complete length. Given the low levels of genome-wide homozygosity prevalent in most human populations, information is required on very large numbers of people to provide sufficient power3,4. Here we use ROH to study 16 health-related quantitative traits in 354,224 individuals from 102 cohorts and find statistically significant associations between summed runs of homozygosity (SROH) and four complex traits: height, forced expiratory lung volume in 1 second (FEV1), general cognitive ability (g) and educational attainment (nominal p<1 × 10−300, 2.1 × 10−6, 2.5 × 10−10, 1.8 × 10−10). In each case increased homozygosity was associated with decreased trait value, equivalent to the offspring of first cousins being 1.2 cm shorter and having 10 months less education. Similar effect sizes were found across four continental groups and populations with different degrees of genome-wide homozygosity, providing convincing evidence for the first time that homozygosity, rather than confounding, directly contributes to phenotypic variance. Contrary to earlier reports in substantially smaller samples5,6, no evidence was seen of an influence of genome-wide homozygosity on blood pressure and low density lipoprotein (LDL) cholesterol, or ten other cardio-metabolic traits. Since directional dominance is predicted for traits under directional evolutionary selection7, this study provides evidence that increased stature and cognitive function have been positively selected in human evolution, whereas many important risk factors for late-onset complex diseases may not have been
