Cholangiocarcinoma (CCA) is the second most common primary liver cancer and is characterized by huge heterogeneity, difficult diagnosis, and poor prognosis. Fibrosis-associated heterogeneity in CCA serves as an indicator of the malignant progression of cancer; however, a precise approach to deciphering fibrosis heterogeneity is still lacking. Typically, the tissue proteome is profiled by analyzing bulk tissues, which gives average results of different cell types, especially for CCA tissues in which cancer cells occupy a very small proportion.

State Key Laboratory of Precision Measurement Technology and Instrument, Department of Precision Instrument, Tsinghua University, Beijing 100084, China.

Optical interferometry enables distance measurement with record-high precision. However, the conventional interference intensity shows fast spatial variations, limiting photodetection to a single spot. The light intensity at this spot is affected by various noises, restricting the signal-to-noise ratio (SNR) of a coherent system.

Electronic address:

The Epstein-Barr virus (EBV) encoded tegument protein BSRF1 plays a significant role in the processes of viral maturation and release, however, it's not clear whether BSRF1 is involved in the modulation of host innate immunity. In this study, we demonstrated that BSRF1 can inhibit interferon β (IFN-β) production by downregulating nuclear factor kappa B (NF-κB) activity and subsequently reducing the yield of inflammatory cytokines, thereby facilitating viral replication. Dual luciferase reporter assays indicated that BSRF1 may inhibit NF-κB signaling at the level of IKK or between IKK and p65, while co-immunoprecipitation experiments revealed its association with multiple critical host adaptor proteins.

Due to the complexity and extreme environment of the deep sea, related research is limited by the level of detection technology, and the overall understanding of this topic is limited. At present, the increasing number of disturbances in the deep sea, such as those caused by deep-sea mining, necessitates the urgent formulation of scientifically informed deep-sea environmental management decisions. In response to this challenge, a data-driven, large-scale, and probability-based benthic habitat classification scheme is proposed for the northern equatorial Pacific.

The rapid and simple detection of circulating tumor cells (CTCs) can help with early diagnosis of tumor diseases and assist clinical judgment of tumor disease development status and prognosis. An important alteration in cancer progression is a significant increase in sialic acid (SA) levels, making sialic acid one of an interesting biomarker for cancer type diversity. Here, novel SERS nano-biosensors were fabricated employing molecularly imprinted polymers (MIPs) particles loaded with Ag nanoparticles (AgNPs) to form high affinity toward sialic acid on CTCs.

Direct Distillation: A Novel Approach for Efficient Diffusion Model Inference.

J Imaging

February 2025

Division of Control and Instrumentation (CI), Nanyang Technological University, Singapore 639798, Singapore.

Diffusion models are among the most common techniques used for image generation, having achieved state-of-the-art performance by implementing auto-regressive algorithms. However, multi-step inference processes are typically slow and require extensive computational resources. To address this issue, we propose the use of an information bottleneck to reschedule inference using a new sampling strategy, which employs a lightweight distilled neural network to map intermediate stages to the final output.
