Metastasis is the major cause for high mortality of lung cancer with underlying mechanisms poorly understood. The scaffolding protein neural precursor cell expressed, developmentally down-regulated 9 (NEDD9) has been identified as a pro-metastasis gene in several types cancers including melanoma and breast cancer. However, exact role related mechanism NEDD9 regulating metastasis still remain largely unknown. Here, we demonstrate that knockdown significantly inhibits migration, invasion cells...

Tick-borne diseases (TBDs) can cause serious economic losses and are very important to animal public health. To date, research on TBDs has been limited in Qinghai-Tibet Plateau, China. This epidemiological investigation was conducted evaluate the distribution risk factors of Anaplasma spp. Ehrlichia chaffeensis livestock Qinghai. A total 566 blood samples, including 330 yaks (Bos grunniens) 236 Tibetan sheep (Ovis aries) were screened. Results showed that A. bovis (33.3%, 110/330)...

In the co-phasing techniques applied to segmented telescope, a Shack-Hartmann wavefront sensor cannot accurately detect piston error of segment. Although phase diversity (PD) algorithm can each segment, it fails reconstruct quickly, and its dynamic range is small. Other technologies, such as prisms or micro-lens arrays, will significantly increase complexity construction cost optical system.

In the realm of cross-network tasks, graph domain adaptation is an effective tool due to its ability transfer abundant labels from nodes in source those target domain. Existing adversarial methods mainly focus on domain-wise alignment. These approaches, while mitigating marginal distribution shift between two domains, often ignore integral aspect structural alignment, potentially leading negative transfer. To address this issue, we propose a joint adaptive convolutional network (JDA-GCN)...
