Pengembangan Perangkat Pembelajaran Matematika Kelas Rendah Berorientasi Model Pembelajaran Diskusi

This development was aimed at creating learning device for low level mathematics to increase the students\u27 participation and achievement through discussion learning model in Class A of the second semester of the Elementary School Teacher Education Department of Muhammadiyah University of Purwokerto of the academic year 2008/2009. The 49 subject takers was divided into 15 groups of 3 to 4 people. The procedure of developing the device used classroom action research. The action consisted of two cycles and took three months. Each cycle was done depending on the obtained improvement, design and the factor to be developed. The instrument which was used to get the data of participation and students\u27 response towards the lecture and the learning device was questioner, while he instrument to get data on students learning achievement were essay quiz, mid term test, and the end term test. The result was the device for learning low level mathematics, early-class learning material, students work, and increased learning participation. The learning achievement was still low which was due to their low ability in solving mathematical problem. Key words: Discussion learning model, participation, and mathematics learning achievement

Balancing intestinal and systemic inflammation through cell type-specific expression of the aryl hydrocarbon receptor repressor

As a sensor of polyaromatic chemicals the aryl hydrocarbon receptor (AhR) exerts an important role in immune regulation besides its requirement for xenobiotic metabolism. Transcriptional activation of AhR target genes is counterregulated by the AhR repressor (AhRR) but the exact function of the AhRR in vivo is currently unknown. We here show that the AhRR is predominantly expressed in immune cells of the skin and intestine, different from other AhR target genes. Whereas AhRR antagonizes the anti-inflammatory function of the AhR in the context of systemic endotoxin shock, AhR and AhRR act in concert to dampen intestinal inflammation. Specifically, AhRR contributes to the maintenance of colonic intraepithelial lymphocytes and prevents excessive IL- 1β production and Th17/Tc17 differentiation. In contrast, the AhRR enhances IFN-γ-production by effector T cells in the inflamed gut. Our findings highlight the physiologic importance of cell-type specific balancing of AhR/AhRR expression in response to microbial, nutritional and other environmental stimuli

The Japanese Clinical Practice Guideline for acute kidney injury 2016

Acute kidney injury (AKI) is a syndrome which has a broad range of etiologic factors depending on different clinical settings. Because AKI has significant impacts on prognosis in any clinical settings, early detection and intervention are necessary to improve the outcomes of AKI patients. This clinical guideline for AKI was developed by a multidisciplinary approach with nephrology, intensive care medicine, blood purification, and pediatrics. Of note, clinical practice for AKI management which was widely performed in Japan was also evaluated with comprehensive literature search
