BackgroundInvariant natural killer T (iNKT) cells are an unconventional lymphocyte subset that has garnered increasing attention due to their shared features with both natural killer cells and conventional T cells, as well as their unique dual immunological functions. In this study, we conducted a c...

Resistance of bacteria to antibiotics is a major concern in medicine and veterinary science. The bacterial biofilm structures not only prevent the penetration of drugs into cells within the biofilm’s interior but also aid in evasion of the host immune system. Hence, there is an urgent need to develo...

Abstract Medulloblastoma is a common embryonic malignant tumor in children. Patients with Group 3 medulloblastoma exhibit the poorest prognosis among all subgroups, and approximately 20% of these patients carry an amplification of MYC. Metabolic reprogramming, a hallmark of cancer, includes the pent...

Research backgroundYiQing granules (YQGs) are a patented drug commonly used in clinics in China. However, the quality control index of this preparation is relatively limited, which does not effectively ensure the quality of the product. Thus, a comprehensive quality evaluation of YQGs is lacking.Obj...

Abstract Global lakes are expected to witness a growing incidence of droughts under climate warming, but the propagation from atmospheric water deficit (AWD) to lake drought, mediated by basin water deficit (BWD) as a key intermediary, remains underexplored at the lake basin scale. This study invest...

We investigate the optical nonreciprocity induced by the parametrical amplification and the radiation trapping in an atomic photonic bandgap system both theoretically and experimentally. We use two pumping fields to generate entangled photon pairs from spontaneous parametric four-wave mixing, as wel...
