Once released to circulation upon exercise or cold exposure, irisin stimulates browning of white adipose tissue (WAT) and uncoupling protein I (UCP1) expression, leading to an increase in total body energy expenditure by augmented UCPl-mediated thermogenesis. It is currently unknown whether irisin is secreted by bone upon exercise or whether it regulates bone metabolism in vivo. In this study, we found that 2 weeks of voluntary wheel-running exercise induced high levels of FNDC5 messenger RNA as well as FNDC5/irisin protein expression in murine bone tissues. Increased immunoreactivity due to exercise-induced FNDC5/irisin expression was detected in different regions of exercised femoral bones, including growth plate, trabecular bone, cortical bone, articular cartilage, and bone-tendon interface. Exercise also increased expression of osteogenic markers in bone and that of UCP1 in WAT, and led to bodyweight loss. Irisin intraperitoneal (IP) administration resulted in increased trabecular and cortical bone thickness and osteoblasts numbers, and concurrently induced UCP1 expression in subcutaneous WAT. Lentiviral FNDC5 IP administration increased cortical bone thickness. In vitro studies in bone cells revealed irisin increases osteoblastogenesis and mineralization, and inhibits receptor activator of nuclear factor-kB ligand (RANKL)- induced osteoclastogenesis. Taken together, our findings show that voluntary exercise increases irisin production in bone, and that an increase in circulating irisin levels enhances osteogenesis in mice.展开更多

Based on the quantitative analysis on three correspond- ing game models with four players including local residents, enterprises, local governments and competent authorities at higher levels, this paper demonstrates four main shortcomings of current administrative mechanism of Huaihe River anti-pollution system, including low emission cost, low connivance cost, overemphasis on heavy fine of the enterprises, neglect of the punishment on the local departments and intersected administrative mechanism. This paper sets up anti- pollution administrative mechanism, combining economic method with noneconomic method, government control with market mechanism, and introducing public participation. At last, this paper proposes policies, such as implementing emissions trading system, reforming public participation system, and reforming government’s environmental protection mechanism to promote law enforcement.展开更多

This study aimed to understand coping mechanisms of the elderly with chronic conditions who live with their family. Methods: This study was conducted using a descriptive phenomenology method from the experience of 13 older adults with chronic disease. The study processes were interviewed, tape recorded, transcribed, and explored from the transcripts using Colaizzi’s descriptive phenomenological method. The steps of the descriptive phenomenology process are bracketing, intuiting, analyzing, and describing. Results: The coping mechanisms used by the elderly with chronic diseases are (1) the behavioral focus coping ways by doing sports, and physical activities;(2) Focus on spirituality has been implemented by fasting, chanting, dhikr, and prayer;(3) The cognitive focus by working on hobbies or habitual activities and helping each other;(4) The social interaction focus was by interacting with friends, family, and neighbors. Conclusions: This shows that elderly adults with disease conditions try to adapt various forms of coping mechanisms, which positively affects their psychological state. Families which have elderly with chronic diseases are expected to provide nurturing and psychological support to them so that the elderly can consistently apply coping mechanisms to overcome and tackle chronic diseases. Understanding the coping mechanism implementation of the elderly who have chronic diseases by their family can guide health specialists in designing psychological and spiritual approach interventions.展开更多
