The optimal industrial carbon tax for China under carbon intensity constraints: a dynamic input-output optimization model.

To reduce carbon emissions, the Chinese government is considering introducing a differentiated industrial carbon tax on enterprises outside the carbon trading market in the future. An efficient carbon tax must consider not only how carbon taxes impact the current economy but also how the size of the tax should be adjusted across time due to external changes. To calculate the optimal industrial carbon tax for China which is subject to certain constraints, this paper investigates the economic and environmental effects of four possible industrial carbon tax rate models under carbon intensity constraints from 2021 to 2030 by a dynamic input-output optimization model.

Impact of miR-302b on Calcium-phosphorus Metabolism and Vascular Calcification of Rats with Chronic Renal Failure by Regulating BMP-2/Runx2/Osterix Signaling Pathway.

Objective: To investigate how miR-302b affect the calcium-phosphorus metabolism and vascular calcification (VC) of rats with chronic renal failure (CRF) via the regulation of bone morphogentic proteins 2/Runt-related transcription factor 3/Osterix (BMP-2/Runx2/Osterix) signaling pathway.

Methods: SD rats were selected to establish CRF rat models and assigned into Sham, CRF, CRF + miR-302b, and CRF + miR-NC groups. The biochemical indexes of rats were detected at 8th and 12th week.

Anti-HCV reactive volunteer blood donors distribution character and genotypes switch in Xi'an, China.

HCV is prevailed in the world as well as in China. Blood transfusion is one of the most common transmission pathways of this pathogen. Although data of HCV infection character were reported during the past years, anti-HCV reactive profile of China donors was not fully clear yet.
