Abstract Background Although gemcitabine-based chemotherapy has been established as a core multimodal therapy for non-small cell lung cancer (NSCLC) treatment, its clinical efficacy remains limited by the development of acquired resistance following tumor metastasis and relapse. In this study, we investigated how gemcitabine-resistant (GR) cells contribute to NSCLC malignancy via exosome-mediated transfer microRNAs. Methods We first studied mechanism exosome internalization PKH-67 staining...
Due to the rise of 5G, IoT, AI, and high-performance computing applications, datacenter traffic has grown at a compound annual growth rate nearly 30%. Furthermore, three-fourths resides within datacenters. The conventional pluggable optics increases much slower than that traffic. gap between application requirements capability keeps increasing, trend is unsustainable. Co-packaged (CPO) disruptive approach increasing interconnecting bandwidth density energy efficiency by dramatically...
Bacterial vaginosis (BV) is caused by the excessive and imbalanced growth of bacteria in vagina, affecting 30 to 50% women. Gram staining followed Nugent scoring based on bacterial morphotypes under microscope considered gold standard for BV diagnosis; this method often labor-intensive time-consuming, results vary from person person. We developed optimized a convolutional neural network (CNN) model evaluated its ability automatically identify classify three categories scores images.

The ASSN fabricated mainly through simple sputter deposition processes,...
Abstract For the first time, a configurable NbO x memristor is achieved that can be configured as an artificial synapse or neuron after fabrication by controlling forming compliance current (FCC). When FCC ≤ 2 mA, memristors exhibit resistive‐switching (RS) property, enabling multiple types of synaptic plasticity, including short‐term potentiation, paired‐pulse facilitation, memory, and long‐term memory. ≥ 3 electroformed threshold switching (TS) property with excellent endurance (>10 12...
It is well known that B-1 B cells are the main cell type responsible for production of natural immunoglobulin M (IgM) and can respond to infection by increasing IgM secretion. However, we unexpectedly found some epithelial also express rearranged transcript has characteristics, such as germline-encoded restricted rearrangement patterns.
