Abstract
The PD-1/B7-H1 pathway regulates immune responses and maintains homeostasis. Here, we identified a unique expression of B7 homolog 1 (B7-H1) on masticatory mucosae in the oral cavity. B7-H1 was physiologically expressed on the dorsal surface of the tongue, gingiva, and hard palate. Other squamous epithelia and other structures of the epithelia did not express B7-H1 in the steady state. Physiological B7-H1 expression on masticatory mucosae was limited on prickle cells, and its expression on basal keratinocytes (KCs) was strictly regulated. B7-H1 on prickle cells was upregulated by external topical stimuli, but B7-H1 on basal KCs was induced only by internal stimuli via infiltrating cells. The blocking of KC-associated B7-H1 or the lack of programmed cell death-1 (PD-1) on tissue effector CD4+ T cells in mice lacking B7-H1 on immune cells drastically exacerbated the tissue inflammation induced by topical OVA painting as an exogenous antigen, indicating direct interaction with KCs and CD4+ T cells. Trans-coinhibitory signals by KCs may modulate local T-cell/dendritic cell activation, resulting in inhibition of T-cell responses in both peripheral and secondary lymphoid tissues. Careful control of B7-H1 induction in KCs may play a crucial role in the protection from CD4+ T cell-mediated tissue inflammation by exogenous antigens delivered from the mucosal surface.

Abstract
Abstract
Aim: An educational program delivered through e-learning was conducted, focusing on nursing for primary breast cancer patients. This paper investigates the results of the program, clarifying changes in levels of understanding before and after the program, and evaluations of the program by nurses who participated. Methods: The content of the education program, which consisted of 24 lessons, each lasting 15-20 minutes, including case studies, covered concerns raised in questions by patients and families about diagnosis, multimodal treatment and nursing for primary breast cancer. Instructors were Certified Nurses in Breast Cancer Nursing and Certified Nurse Specialists in Cancer Nursing, and PowerPoint presentations with video and audio material were created. A dedicated website was created, and 1417 participants took the on-demand program, which was provided from September 2015 to March 2016. Survey participants were the first 500 nurses registered for the course to respond. A questionnaire created by the researchers was sent by post to respondents. Responses were anonymous with identifying information code, and questionnaires were sent with a return envelope before the program (within 2 weeks of registration) and after the program (within 1 month of the end of the program), with return of the questionnaire signifying consent to participate. The questionnaire comprised 24 items on level of understanding of breast cancer nursing, aligned to program content, plus 11 items on evaluation of the program. Responses were selected from a 5-point scale, where 1 meant “strongly disagree” and 5 meant “strongly agree”. Analysis: Responses were quantified, and mean scores for each item were calculated. In addition, respondents were divided into two groups, namely, those with less than 3 years of breast cancer nursing experience (Group A) and those with 3 or more years' experience (Group B), and were compared using the Mann-Whitney U test. SPSS Statistics V22.0 was used. Ethical considerations: The study went through Research Ethics approval at the researchers' institute of affiliation. Results: A total of 126 people replied to both the pre-program and post-program questionnaire, and of these, the responses of 106 nurses (Group A: 34 nurses, Group B: 72 nurses) who were not qualified as Certified Nurses or Certified Nurse Specialists were used for analysis. Median age was 41.0 years (Group A: 38.5 years, Group B: 42 years), and median number of years of breast cancer nursing was 4.6 years. In terms of program evaluation, “I could study when it was convenient for me” scored 4.63, while “It will be useful for breast cancer nursing from now on” scored 4.57. In terms of comparison of level of understanding before and after the program, understanding improved on all 24 items, and was significant on 19 items. Comparison of the 2 groups showed significant difference on 2 items, “support for changes in body image” and “communication with the patient”, with changes in level of understanding in Group A being greater. Discussion: The study suggests that participants' understanding of breast cancer nursing increased and improvements in clinical practice can be expected through e-learning materials that facilitate effective learning.

Abstract
For the pretreatment in order to nano prepare porous carbon from biomass such as bamboo, a mixture of acetic acid and hydrogen peroxide was used for the partial delignification of bamboo. The pretreatment should be effective for the removal of lignin because the lignin percentage after the pretreatment depended on the treatment time and the treatment temperature. For the concentration of the mixture used for the pretreatment in this study, a small amount of lignin (ca. 2 wt%) remained even after a sufficiently-long treatment time. The BET specific surface area of the carbon material prepared by the heat treatment at 800 degrees C for 1 h under flowing N2 was related to the pretreatment conditions, and the specific surface areas of the samples were found to be related to the lignin percentage. The removal of lignin while maintaining the microstructure derived from plant tissue could be the reason for the local maximum of the specific surface area at ca. 5% of the lignin.

Abstract
Senescence marker protein-30 (SMP30) decreases androgen-independently with aging and is a lactone-hydrolyzing enzyme gluconolactonase (GNL) that is involved in vitamin C biosynthesis. In the present study, bone properties of SMP30/GNL knockout (KO) mice with deficiency in vitamin C synthesis were investigated to reveal the effects of SMP30/GNL and exogenous vitamin C supplementation on bone formation. Mineral content (BMC) and mineral density (BMD) of the mandible and femur of SMP30/GNL KO and wild-type mice at 2 and 3 months of age with or without vitamin C supplementation were measured by dual-energy X-ray absorptiometry. Body and bone weight of both age groups decreased and became significantly lower than those of wild-type mice. The bones of SMP30/GNL KO mice were rough and porous, with BMC and BMD significantly below wild-type. Oral supplementation with vitamin C eliminated differences in body weight, bone weight, BMC, and BMD between SMP30/GNL KO and wild-type mice at each age. These results indicate that bone degeneration in SMP30/GNL KO mice was caused by lack of vitamin C, and that this mouse strain is an appropriate model for bone metabolism in humans, which have no ability to synthesize vitamin C.
