Along with the decreased activity of antioxidant enzymes SOD and GPx, the brain of hyperglycemic fish presented a reduction in mRNA transcription of FoxO3A, FoxO3B, Nrf2, GPx3A, SOD1, and SOD2 genes. Besides normalizing the transcriptional levels, DD caused an up-regulation of relative mRNAs that encode Nrf2, FoxO1A, FOXO3A, GPx4A, PTP1B, AKT and SelP. Collectively, our findings suggest that the antioxidant and anti-hyperglycemic actions of DD in a zebrafish diabetes model are likely associated with the regulation of the oxidative stress resistance and the insulin-signaling pathway and that could be related to the modulation at mRNA level of two important transcription factors, Nrf2 and FoxO.Background Preoperative planning with commercially available imaging software in shoulder arthroplasty may allow for improved decision making and more accurate placement of the glenoid component. Methods 81 consecutive shoulder computed tomography (CT) scans obtained for preoperative planning purposes for shoulder arthroplasty were analyzed by commercially available software from four companies (Blueprint - Wright Medical, Memphis, TN; GPS - Exactech, Gainesville, FL, USA; Materialise - DJO, Vista, CA, USA; and VIP - Arthrex, Naples, FL, USA), and by 5 fellowship trained sports medicine/shoulder surgeons. Inclination, version and subluxation of the humerus were measured in a blinded fashion on axial and coronal sequences at the mid-glenoid. Surgeon measurements were analyzed for agreement, and were compared to the 4 commercial programs. Results Surgeon reliability was acceptable for version (intraclass correlation coefficient (ICC) 0.876), inclination (ICC0.84), and subluxation (ICC 0.523). Significant differences were found between surgeon and commercial software measurements in version (p=0.03), inclination (p=0.023) and subluxation (p less then 0.001). Software measurements tended to be more superiorly inclined (average -2° to 2° greater), more retroverted (average 2°-5° greater) and more posteriorly subluxed (average 7°-10° greater) than surgeon measurements. In comparing imaging software measurements only Blueprint produced significantly different version measurements than surgeon measurements (p=0.02). Conclusion Preoperative planning software for shoulder arthroplasty has limited agreement in measures of version, inclination and subluxation measurements while surgeons have high inter-reliability. Surgeons should be cautious when using commercial software planning systems and when comparing publications that use different planning systems to determine preoperative glenoid deformity measurements.The use of genomic approaches in toxicological studies has greatly increased our ability to define the molecular profiles of environmental chemicals associated with developmental neurotoxicity (DNT). Integration of these approaches with adverse outcome pathways (AOPs), a framework that translates environmental exposures to adverse developmental phenotypes, can potentially inform DNT testing strategies. Here, using retinoic acid (RA) as a case example, we demonstrate that the integration of toxicogenomic profiles into the AOP framework can be used to establish a paradigm for chemical testing. RA is a critical regulatory signaling molecule involved in multiple aspects of mammalian central nervous system (CNS) development, including hindbrain formation/patterning and neuronal differentiation, and imbalances in RA signaling pathways are linked with DNT. While the mechanisms remain unresolved, environmental chemicals can cause DNT by disrupting the RA signaling pathway. First, we reviewed literature evidence of RA and other retinoid exposures and DNT to define a provisional AOP related to imbalances in RA embryonic bioavailability and hindbrain development. Next, by integrating toxicogenomic datasets, we defined a relevant transcriptomic signature associated with RA-induced developmental neurotoxicity (RA-DNT) in human and rodent models that was tested against zebrafish model data, demonstrating potential for integration into an AOP framework. Finally, we demonstrated how these approaches may be systematically utilized to identify chemical hazards by testing the RA-DNT signature against azoles, a proposed class of compounds that alters RA-signaling. The provisional AOP from this study can be expanded in the future to better define DNT biomarkers relevant to RA signaling and toxicity.Quinolone-based Schiff base zirconium(IV) complex was studied as potential bacterial inhibitor against Gram-positive Staphylococcus aureus and Gram-negative Salmonella typhi growth, showing that the interaction of the complex with L-glutamine which presents in the membrane of wall leads cell death, and the mode of bacterial interaction was analyzed theoretically by DFT. Ruboxistaurin Furthermore, the interaction of different amino acid residues L-alanine, D-alanine, L-lysine and D-glutamine with the metal complex through UV-vis docking studies was conducted observing that D-glutamine interacts efficiently among other amino acid residues. This observation is consistent with the interaction of the metal complex that was effective when participating in an insight of the peptidoglycan cell wall since the binding nature of glutamine potentially inhibits these microorganisms.Lennox-Gastaut Syndrome (LGS) is a rare form of childhood epilepsy. Rufinamide is an orphan drug indicated for the treatment of LGS. Three-Dimensional Printing (3DP) is a process in which solid objects are created based on a digital file by adding materials layer by layer. Fused deposition modelling (FDM) is a 3DP technique with the advantages of solid dispersion systems and the ability to use various pharmaceutical excipients in small scales, which makes this technology favorable for the production of orphan drugs. Rufinamide is a water-insoluble lipophilic compound which can exist in different polymorphic forms. The therapeutic dose is 3200 mg/day, at which rufinamide exhibits nonlinear pharmacokinetics, which may be attributed to its limited solubility. The main purpose of this paper is to improve the dissolution of rufinamide through the use of 3DP technology. For this purpose, optimum 3DP tablets were developed based on 3DP manufacturability and dissolution behaviors. The findings suggest that a mixture of hydroxypropyl methylcellulose (HPMC), Soluplus®, Kollidon® VA64, Gelucire® 48/16 and Triacetin are suitable excipients for FDM-3DP technology that can improve the dissolution of rufinamide.
