86, emotional α = 0.90, external α = 0.86). Results of multi-group confirmatory factor analysis supported its metric and scalar or partial scalar measurement invariance across all subgroups. In gender subgroup, girls scored higher on restrained eating. In school subgroup, junior high school children scored higher on emotional and external eating. In BMI subgroup, overweight children scored higher on restrained eating. These findings suggest that the Japanese version of the DEBQ-C is a psychometrically valid and reliable instrument for assessing eating behaviors across gender, school categories, and BMI categories in Japanese children. Anthraquinones are found in a variety of consumer products such as dietary supplements, traditional Chinese medicines, and drugs. Along with their widespread use, potential safety concerns have emerged, especially liver toxicity. Therefore, there is a need to conduct rapid and inexpensive safety assessment for anthraquinones due to a lack of animal and human toxicological data. Here, a combined in vitro cytotoxicity and in silico reverse dosimetry approach was adopted to consider the potential human liver toxicity of 16 anthraquinones and derivatives. First, cytotoxicity (EC50) in two human liver cell lines (HepG2/C3A and HuH-7) was measured under two conditions (single and repeated dosing, 72 h). Second, toxic doses (Dtox) required to yield plasma steady-state concentrations (Css) equal to in vitro EC50 values were predicted by reverse dosimetry simulation using a PBPK model. Finally, Dtox was compared to literature-derived estimated daily intake (EDI) of anthraquinones to assess safety. Among the 16 anthraquinones, rhein was identified as a potential hepatotoxicant due to a combination of cytotoxicity, plasma concentration, and daily intake level. These in vitro and in silico findings provide preliminary data and guidance for further animal and clinical studies to confirm liver toxicity of anthraquinones.

Meanwhile, accumulating evidence has shown that miR-155-5p is activated in the inflammatory response. As molecular pathways and mechanisms involved in T-2 toxin-induced inflammatory response are poorly elucidated, we assessed whether miR-155-5p is involved in the inflammation effects mediated by T-2 toxin. Treatment of RAW264.7 cells with T-2 toxin (14 nM and 12 h) resulted in inflammatory response and associated with alteration of the gene expression signature of miR-155-5p. Knockdown or overexpression of miR-155-5p both indicated that miR-155-5p positively regulated the expression of the inflammation factors. Moreover, bioinformatics prediction and luciferase assay indicated that atg3 and rheb are targets of miR-155-5p. However, atg3 and SOCS1 play positive roles in the inflammatory response regulated by miR-155-5p, while rheb plays a negative role. In addition, the in vivo study showed that single administration of T-2 toxin in mice enhances spleen immune response, which was accompanied by an overexpression of miR-155-5p. These findings indicate that miR-155-5p might have an important role associated with the inflammatory response induced by T-2 toxin. In conclusion, a dual character of miR-155-5p in inflammation response was revealed, which might exist in other reactions in which miR-155-5p is involved. X-ray absorption fine structure (XAFS) spectra, especially X-ray absorption near-edge structure (XANES), show unique features depending on the chemical states and structures in the vicinity of the X-ray absorbing elements. As such, they can be used to identify the chemical environment of elements. XAFS spectroscopy was applied to investigate the chemical environment of chloride ions in a metastable form A crystal of the antibiotic clarithromycin hydrochloride hydrate. The XANES of the form A crystals showed low similarity to that of the active pharmaceutical ingredient (API) hydrochloride salt crystals, but showed a high similarity to that of a hydrochloride aqueous solution. This indicated that the chloride ion in the form A crystals predominantly interacted with water molecules and was fully hydrated, which was consistent with the previous presumption that form A may be high water-content crystals. This study demonstrated that this XAFS spectroscopy method would be a potent alternative technique for evaluating APIs. The treatment of peripheral nerve injury is still a challenge. The present study was aimed to fabricate a composite nerve conduit containing slow-released brain-derived neurotrophic factor (BDNF) and evaluate its therapeutic effects on peripheral nerve defect. selleckchem BDNF and polylactic acid (PLA) were mixed together and a BDNF-loaded composite conduit was fabricated by solvent evaporation method. The bioactivity of BDNF released from the composite conduit was measured by MTT assay. A rat sciatic nerve defect model was used to compare regeneration potentials of autologous nerve graft, conduit filled with saline, conduit filled with BDNF solution and BDNF composite conduit. Nerve-regeneration was evaluated 3 months after surgery. The results demonstrated BDNF composite conduits prepared in this study remained bioactive for at least 3 months, and can promote the regeneration of sciatic nerve with a 10-mm gap in rats. Different solid forms possess various physicochemical properties, which can significantly affect the stability, bioavailability, and manufacturability of the final product. DP-VPA, a complex of 1-stearoyl-2-valproyl-sn-glycero-3-phosphatidylcholine (DP-VPA-C18) and 1-palmitoyl-2-valproyl-sn-glycero-3-phosphatidylcholine (DP-VPA-C16), is currently under development as an antiepileptic drug. DP-VPA-C16 and DP-VPA-C18 crystallize together in solid solution forms. The solid forms of DP-VPA solid solution were studied herein. Powder X-ray diffraction (PXRD), thermogravimetric analysis (TGA), differential scanning calorimetry (DSC), attenuated total reflection Fourier transform infrared spectroscopy (ATR-FTIR), scanning electron microscopy (SEM), dynamic vapor sorption (DVS) and optical microscopy were used to characterize the different crystalline forms, known as polymorphs. The physicochemical properties, including hygroscopicity, thermodynamic behavior, and relative stability, of each form were investigated. DVS analysis showed that DP-VPA solid solution reduced the hygroscopicity of DP-VPA-C16.
