Pasteurella multocida (P. multocida) is an important pathogenic bacterium that poses a serious threat to the development of livestock economy and human health. Currently, existing methods for P. detection are time-consuming require complex professional operations, limiting application field detection. In study, we presented single-pot naked-eye CRISPR-Cas12a platform (Cas12a-NEye) multocida. The round tube cover allowed more Cas12a solution be temporarily stored than flat cap, enabling...

With the tremendous success of large language models such as ChatGPT, artificial intelligence has entered a new era models. Multimodal data, which can comprehensively perceive and recognize physical world, become an essential path towards general intelligence. However, multimodal trained on public datasets often underperform in specific industrial domains. In this paper, we tackle problem building vision-language intelligent for domains by leveraging federated learning. We compare challenges...

Herein we describe the design and synthesis of a series pyridopyrazine-1,6-dione γ-secretase modulators (GSMs) for Alzheimer's disease (AD) that achieve good alignment potency, metabolic stability, low MDR efflux ratios, while also maintaining favorable physicochemical properties. Specifically, incorporation fluorine enabled metabolically less liable lipophilic alkyl substituents to increase potency without compromising sp(3)-character. The lead compound 21 (PF-06442609) displayed rodent...
