Local Control of Conjunctival Malignant Melanoma by Proton Beam Therapy in a Patient With No Metastasis in Six Years From to Nodular Lesions.

Conjunctival malignant melanoma is extremely rare, with no standard of care established at moment. Here we report a 65-year-old woman, as a hepatitis B virus (HBV) carrier, who presented concurrently a liver mass and lower bulbar conjunctival pigmented lesions in the right eye. Needle liver biopsy and excisional conjunctival biopsy showed hepatocellular carcinoma and conjunctival malignant melanoma , respectively.

Risk of artery dissection during systemic exposure to vascular endothelial growth factor pathway inhibitors.

Whether or not vascular endothelial growth factor pathway inhibitors (VPIs) increase the risk of artery dissection is still unknown. This study aimed to quantitatively evaluate the possibility of artery dissection as a class effect of VPIs using nationwide real-world data. This cohort study was conducted based on the National Database of Health Insurance Claims and Specific Health Checkups of Japan (NDB), which spans nearly the entire Japanese population of over 100 million individuals.

Radiation hepatitis after postmastectomy radiation therapy for early breast cancer: difficult to differentiate from drug-induced liver injury caused by abemaciclib.

Abemaciclib (ABM) is recommended for adjuvant endocrine therapy in hormone receptor-positive, human epidermal growth factor receptor type 2-negative early breast cancer (EBC) patients at high risk of recurrence. Here, we present a case of radiation hepatitis challenging to differentiate from drug-induced liver injury during ABM treatment. The patient, a woman in her 40 s, underwent right mastectomy, axillary dissection, and postmastectomy radiation therapy (PMRT) after neoadjuvant chemotherapy for EBC.

Perioperative surveillance of myocardial injury after non-cardiac surgery in patients with hip fracture: A retrospective cohort study.

Structural insights into catalytic promiscuity of chalcone synthase from Glycine max (L.) Merr.: Coenzyme A-induced alteration of product specificity.

Catalytic promiscuity of enzymes plays a pivotal role in driving the evolution of plant specialized metabolism. Chalcone synthase (CHS) catalyzes the production of 2',4,4',6'-tetrahydroxychalcone (THC), a common precursor of plant flavonoids, from p-coumaroyl-coenzyme A (-CoA) and three malonyl-CoA molecules. CHS has promiscuous product specificity, producing a significant amount of p-coumaroyltriacetic lactone (CTAL) in vitro.

Magnon thermal Hall effect via emergent SU(3) flux on the antiferromagnetic skyrmion lattice.

Complexity of quantum phases of matter is often understood theoretically by using gauge structures, as is recognized by the [Formula: see text] and U(1) gauge theory description of spin liquids in frustrated magnets. Anomalous Hall effect of conducting electrons can intrinsically arise from a U(1) gauge expressing the spatial modulation of ferromagnetic moments or from an SU(2) gauge representing the spin-orbit coupling effect. Similarly, in insulating ferro and antiferromagnets, the magnon contribution to anomalous transports is explained in terms of U(1) and SU(2) fluxes present in the ordered magnetic structure.

Structural-Functional Correlations between Unique N-terminal Region and C-terminal Conserved Motif in Short-chain cis-Prenyltransferase from Tomato.

Neryl diphosphate (C) synthase (NDPS1), a homodimeric soluble cis-prenyltransferase from tomato, contains four disulfide bonds, including two inter-subunit S-S bonds in the N-terminal region. Mutagenesis studies demonstrated that the S-S bond formation affects not only the stability of the dimer but also the catalytic efficiency of NDPS1. Structural polymorphs in the crystal structures of NDPS1 complexed with its substrate and substrate analog were identified by employing massive data collections and hierarchical clustering analysis.
