In celebration of the 30th anniversary of China-Mozambique diplomatic relations, Mozambique National Song & Dance Ensemble toured China at the invitation of Chinese Ministry of Culture in the early summer of 2005. The ensemble staged marvelous performances with rich African flavors in Beijing, Jiangxi and Zhejiang, showcasing artistic diversity and extraordinary vitality of Mozambique's dancers and singers. Their unique understanding of life, thinking of history and expectation of future, as demonstrated in their talented dancing and singing, has won unanimous recognition and acclaim of Chinese audience, 相似文献

The outbreak of the COVID-19 pandemic was partially due to the challenge of identifying asymptomatic and presymptomatic carriers of the virus, and thus highlights a strong motivation for diagnostics with high sensitivity that can be rapidly deployed. On the other hand, several concerning SARS-CoV-2 variants, including Omicron, are required to be identified as soon as the samples are identified as ‘positive’. Unfortunately, a traditional PCR test does not allow their specific identification. Herein, for the first time, we have developed MOPCS (Methodologies of Photonic CRISPR Sensing), which combines an optical sensing technology-surface plasmon resonance (SPR) with the ‘gene scissors’ clustered regularly interspaced short palindromic repeat (CRISPR) technique to achieve both high sensitivity and specificity when it comes to measurement of viral variants. MOPCS is a low-cost, CRISPR/Cas12a-system-empowered SPR gene-detecting platform that can analyze viral RNA, without the need for amplification, within 38 min from sample input to results output, and achieve a limit of detection of 15 fM. MOPCS achieves a highly sensitive analysis of SARS-CoV-2, and mutations appear in variants B.1.617.2 (Delta), B.1.1.529 (Omicron) and BA.1 (a subtype of Omicron). This platform was also used to analyze some recently collected patient samples from a local outbreak in China, identified by the Centers for Disease Control and Prevention. This innovative CRISPR-empowered SPR platform will further contribute to the fast, sensitive and accurate detection of target nucleic acid sequences with single-base mutations. 相似文献

The history of Chinese library undertaking shows that the development of libraries is subject to the reinforcement of political domination, the need of ideological domination, the rise of education and the development of cultural exchange and the academic research as well. The development of culture breeds and promotes libraries, and libraries in turn, exert an active influence over the development of cultures 相似文献
