Ceramics production methods in Chenlu date back to the famous Tang Dynasty (618-907) Yaozhou Kiln, and the quality of their products remains peerless. The demand for Yaozhou ceramic reached its zenith during the Song Dynasty (960-1279), when they were regarded as the ultimate imperial tribute.展开更多

By using this method, we found that, whereas ITSs are heterochromatic, Arabidopsis telomeres exhibit euchromatic features [1]. Some concerns have been recently raised about the accuracy of this procedure [2]. Here, we summarize these concerns and justify our experimental approaches and interpretation of results.展开更多

This study focuses on human telomeric chromatin structure using different techniques like Chromatin Immunoprecipitation (ChIP), cytolocalization or RT-qPCR. However, it has been performed without taking into consideration the presence of Interstitial Telomeric Sequences (ITSs) in the human genome. Some of the conclusions of the article are undoubtedly clear but there are others that might be explained in alternative ways, considering the existence of ITSs. Following, we mention some comments that arise from this interesting article.展开更多
