We are participating in the challenge of identifying active compounds for target proteins using structure-based virtual screening (SBVS). We use an in-house customized docking program, CONSENSUS-DOCK, which is a customized version of the DOCK4 program in which three scoring functions (DOCK4, FlexX and PMF) and consensus scoring have been implemented. This paper compares the docking calculation results obtained using CONSENSUS-DOCK and DOCK4, and demonstrates that CONSENSUS-DOCK produces better results than DOCK4 for major X-ray structures obtained from the Protein Data Bank (PDB).

In this study, we analyze InO thin-film transistors (InO-TFT) using synchrotron-based hard X-ray photoelectron spectroscopy (HAXPES) in conditions. A bottom-gate InO-TFT with a high- AlO gate dielectric, grown on thermally oxidized silicon (SiO/p-Si), was examined while operating at varying and . The results reveal that the In 3d core level binding energy varies along the horizontal channel length, driven by the potential gradient induced by .

Rationale And Objectives: The thyroid foramen (TF) is a congenital anatomical variant of the thyroid cartilage, characterized by a small opening that may transmit neurovascular structures. Although benign, TF can be misinterpreted on imaging as a cartilage fracture or tumor invasion, and may pose a surgical risk if unrecognized. Despite these potential implications, TF remains under-recognized in routine radiological practice.

Phycobilisome (PBS) is a water-soluble light-harvesting supercomplex found in cyanobacteria, glaucophytes, and rhodophytes. PBS interacts with photosynthetic reaction centers, specifically photosystems II and I (PSII and PSI), embedded in the thylakoid membrane. It is widely accepted that PBS predominantly associates with PSII, which functions as the initial complex in the linear electron transport chain.

Four novel coumarin-containing arenes bearing a [5]/[6]helicene unit (, , , and ) have been readily synthesized and structurally verified by X-ray crystallographic analysis. The chiral resolution of molecules , , and has enabled a detailed investigation of their chiroptical properties and the kinetics of enantiomerization, manifesting that the [6]helicenes and exhibit a more enhanced chiroptical response compared to [5]helicene .

Alstoniaschines A‒I (1‒9), nine previously alkaloids sharing five different skeletons were obtained from the leaves of Alstonia scholaris. The structures and absolute configurations were established by their extensive spectroscopic data analyses, including NMR, HRESIMS, X-ray crystallography data, and theoretical ECD calculations. Compounds 1, 2, 3, and 9 exerted significant protective effect against oxidative stress and inflammatory damage of podocytes induced by high glucose, manifesting as the increase of superoxide dismutase, catalase, glutathione peroxidase, alongside the reductions of malondialdehyde, nitric oxide, lactate dehydrogenase.
