Integrated analysis on socio-economic metabolism could provide a basis for understanding and optimizing regional sustainability. The paper conducted socio-economic metabolism analysis by means of the emergy accounting method coupled with data envelopment analysis and decomposition analysis techniques to assess the sustainability of Qingyang city and its eight sub-region system, as well as to id...

Urban problems—such as resources depletion, environment pollution and waste generation—usually occur during rapid urbanisation processes, especially in mega-urban agglomerations. Finding solutions to sustainable urban development is a global research interest, and urban metabolism is an effective approach to analysing the socio-economic system and ecosystem. In this study, three cities in the J...

background: the aim of the study was to research concerning the epidemiology of newborns' galactosemia during 2007-2008 to find out whether screening was necessary for iranian newborns or not and also what the symptoms of this disease before or after diet were. methods: the data were collected from 24000 newborn babies from fars province, southern iran. the enzymatic calori­metric test was done...

bone is formed through the processes of endochondral and intramembranous ossification. in endochondral ossification primary mesenchymal cells differentiate to chondrocytes and then are progressively substituted by bone, while in intramembranous ossification mesenchymal stem cells (mscs) differentiate directly into osteoblasts to form bone. the steps of osteogenic proliferation, differentiation,...

Fagopylum tatarium (L.) Gaertn (buckwheat) can be used both as medicine and food is also an important crop in barren areas has great economic value. Exploring the molecular mechanisms of response to cadmium (Cd) stress provide theoretical reference for improving buckwheat yield quality. In this study, perennial tartary DK19 was experimental material, its key metabolic pathways Cd were identifie...

A macrolevel approach for integrating regional economic models with urban metabolism models is developed. Challenges with consistency and aggregation persist in the integration of urban models between socioeconomic and environmental systems, and between the micro and macro scale. Using an econometric model as a foundation offers a flexible structure, with low data requirements, that might poten...

background and aims: medicinal plants are a valuable resource for flavonoids extraction. prosopis fracta is one of the plants with medicinal properties. prosopis fracta was found in abundance in southern regions in iran. coersetin is medicinal substance found in the fruit of this plant. quercetin is used in treatment of cancer and viral infections. this study was conducted to determine the quer...

context:micrornas (mirnas) are a class of short, endogenously-initiated, non-coding rnas that post-transcriptionally control gene expression via translational repression or mrna turnover. mirnas have attracted much attention in recent years as they play critical roles in gene expression and are promising tools with many biotech and therapeutic applications. the molecular mechanisms underlying t...
