Nagilactone C from the Seeds of Podocarpus nakaii May Protect Against LPS-Induced Acute Lung Injury via STAT Signaling Pathway Inhibition Open
Background/Objectives: Acute lung injury (ALI) is a respiratory disorder lacking specific targeted therapy. Our preliminary screening revealed that the ethanol extract of the seeds of Podocarpus nakaii (EESPN) alleviated the symptoms of AL…

Quantum causal inference with extremely light touch Open
We give a causal inference scheme using quantum observations alone for a case with both temporal and spatial correlations: a bipartite quantum system with measurements at two times. The protocol determines compatibility with five causal st…

Quantum causal inference via scattering circuits in NMR Open
We report NMR scattering circuit experiments that reveal causal structure. The scattering circuit involves interacting a probe qubit with the system of interest and finally measuring the probe qubit. The scattering circuit thereby implemen…

Experimental demonstration of quantum causal inference via noninvasive measurements Open
We probe the foundations of causal structure inference experimentally. The causal structure concerns which events influence other events. We probe whether causal structure can be determined without intervention in quantum systems. Interven…

Discovery of Prenyltransferase-Guided Hydroxyphenylacetic Acid Derivatives from Marine Fungus Penicillium sp. W21C371 Open
Traditional isolation methods often lead to the rediscovery of known natural products. In contrast, genome mining strategies are considered effective for the continual discovery of new natural products. In this study, we discovered a uniqu…

Unification of spatiotemporal quantum formalisms: mapping between process and pseudo-density matrices via multiple-time states Open
We consider the relation between three different approaches to defining quantum states across several times and locations: the pseudo-density matrix (PDM), the process matrix, and the multiple-time state approaches. Previous studies have s…

α-Glucosidase Inhibitors from Two Mangrove-Derived Actinomycetes Open
α-Glucosidase (AGS) inhibitors have been regarded as an ideal target for the management of type 2 diabetes mellitus (T2DM) since they can maintain an acceptable blood glucose level by delaying the digestion of carbohydrates and diminishing…

Using a National Representative Sample to Evaluate the Integrity of the 30-Day Surgical Mortality Metric Open
The 30-day surgical mortality metric is endorsed by the National Quality Forum for value-based purchasing purposes. However, its integrity has been questioned, as there is documented evidence of hospital manipulation of this measure, by wa…
