Abstract:

Phosphorus-containing cyclic nitrones, such as DEPMPO, CYPMPO, and DPPMPO, were oxidized by hydrogen tetrachloroaurate(III) to DEPMPOX, CYPMPOX, and DPPMPOX with the precipitation of Au(0). The reaction was depressed by the addition of chloride or hydroxide ions. The peculiar pH dependency was observed in DEPMPOX, CYPMPOX, and DPPMPOX formation, which should be caused by the diethoxyphosphoryl group in DEPMPO, the 1,3-propoxy cyclophosphoryl group in CYPMPO, and the diphenylphosphinoyl group in DPPMPO. The oxidation of the nitrones proceeded through the ligand exchange of Cl– in AuCl4– with >N+–O– in nitrone and the nucleophilic addition of the water molecule to the C-2 position in the nitrones, the stepwise intra-molecular transfer of three electrons from the nitrones to Au(III), and the release of the resulting Au(0). The phosphoryl group in the nitrones suppressed the first ligand-exchange interaction by its electronegativity, while the group promoted the electron transfer from the nitrones to Au(III) by its inductive effect.

Abstract:

Unsaturated lipids are rapidly oxidized to toxic products such as lipid hydroperoxides, especially when transition metals such as iron or copper are present. In a Fenton-type reaction Fe2+ converts lipid hydroperoxides to the very short-lived lipid alkoxyl radicals. The reaction was started upon the addition of Fe2+ to an aqueous linoleic acid hydroperoxide (LOOH) emulsion and the spin trap in the absence of oxygen. Even when high concentrations of spin traps were added to the incubation mixture, only secondary radical adducts were detected, probably due to the rapid re-arrangement of the primary alkoxyl radicals. With the commercially available nitroso spin trap MNP we observed a slightly immobilized ESR spectrum with only one hydrogen splitting, indicating the trapping of a methinyl fragment of a lipid radical. With DMPO or 5-diethoxyphosphoryl-5-methyl-1-pyrroline N-oxide (DEPMPO) adducts were detected with carbon-centered lipid radical, with acyl radical, and with the hydroxyl radical. We also synthesized lipophilic derivatives of the spin trap DEPMPO in order to detect lipid radical species generated in the lipid phase. With all spin traps studied a lipid-derived carbon-centered radical was obtained in the anaerobic incubation system Fe2+/LOOH indicating the trapping of a lipid radical, possibly generated as a secondary reaction product of the primary lipid alkoxyl radical formed. Under aerobic conditions an SOD-insensitive oxygen-centered radical adduct was formed with DEPMPO and its lipophilic derivatives. The observed ESR parameters were similar to those of alkoxyl radical adducts, which were independently synthesized in model experiments using Fe3+-catalyzed nucleophilic addition of methanol or t-butanol to the respective spin trap.

Abstract:

Abstract EMPO [5-(ethoxycarbonyl)-5-methyl-1-pyrroline N-oxide] is a highly hydrophilic cyclic nitrone spin trap, whose superoxide adduct is considerably more stable (t1/2=8.6 min) than DMPO (5,5-dimethyl-1-pyrroline Noxide, t1/2=45 s). EPR spectra of spin adducts of EMPO and its derivatives are very similar to those of the respective DMPO spin adducts, in contrast to the rather complex spectra obtained using DEPMPO [5- (diethoxyphosphoryl)-5-methyl-1-pyrroline Noxide]. Several EMPO derivatives, with both the ethoxycarbonyl group and the methyl group at position 5 of the pyrroline ring being replaced by other substituents, were synthesized and characterized by 1H and 13C NMR spectroscopy. Thus, a series of derivatives was obtained that exhibit large differences in the stability of their superoxide adducts, ranging from less than one to more than 25 min. The stability of the superoxide adducts was mainly determined by the steric environment of the nitroxyl group: in compounds with less bulky 5-alkoxycarbonyl substituents the nitroxyl group is sterically less shielded, which resulted in a lower stability of the superoxide adducts. The spin density distribution, as obtained from DFT computations, was found to be nearly identical for all compounds, so that in contrast to the steric influences the spin density did not seem to be a crucial factor for the stability of the superoxide adducts.

Abstract:

The antioxidant effect of dinitrosyl iron complexes (DNICs) was studied in various model systems. DNICs with glutathione ligands effectively inhibited Cu2+-induced peroxidation of low density lipoproteins (LDL). The antioxidant effect of DNICs with phosphate ligands and free reduced glutathione (GSH) was less pronounced. In addition, DNICs with glutathione suppressed the formation of reactive oxygen species during co-oxidation of lecithin liposomes and glucose. Free radical oxidation in this system was induced with a lipophilic azo initiator and evaluated by luminol-dependent chemiluminescence. NO sharply stimulated chemiluminescence during co-oxidation of glucose and liposomes, thus suggesting the formation of potent oxidants under these conditions. Glutathione DNICs scavenge the superoxide radical anion generated in the xanthine-xanthine oxidase system. Superoxide production was assessed by lucigenin-dependent chemiluminescence and electron paramagnetic resonance (EPR) spectroscopy. Chemiluminescence revealed the dose-dependent character of antiradical effect of glutathione DNICs; moreover, these complexes turned out to be more efficient than GSH. EPR spectra of the adducts of the DEPMPO spin trap with free radicals suggest that the interaction of glutathione DNICs and superoxide does not result in the formation of the thiyl radical of glutathione. Here we propose a mechanism of the antioxidant action of glutathione DNICs, suggesting that unstable intermediate complexes are formed upon their interaction with superoxide or lipid radicals. Further, as a result of intramolecular rearrangement, these intermediates decompose without the free radical as the by-products.

Abstract:

Objective: Children/adolescent's orodental structures are different in anatomy and physiology from that of adults, therefore require special attention for bleaching with oxidative materials. Hydroxyl radical (OH.) generation from bleaching agents has been considered directly related to both its clinical efficacy and hazardous effect on orodental structures. Nonetheless bleaching agents, indirectly releasing hydrogen peroxide (H2O2), are considered safer yet clinically efficient. Apart from OH., perhydroxyl radicals (HO2.) too, were detected in bleaching chemistry but not yet in dentistry. Therefore, the study aims to detect the OH. and HO2. from bleaching agents with their relative integral value (RIV) using 31P nuclear magnetic resonance (31PNMR) spectroscope. Study design: Radicals were generated with UV light in 30% H2O2, 35% carbamide peroxide (CP), sodium perborate tetrahydrate (SPT) and; neutral and alkaline 30% H2O2. Radicals were spin-trapped with DIPPMPO in NMR tubes for each test agents as a function of time (0, 1, 2, 3min) at their original pH. Peaks were detected for OH. and HO2. on NMR spectrograph. RIV were read and compared for individual radicals detected. Results: Only OH. were detected from acidic and neutral bleaching agent (30% acidic and neutral H2O2, 35%CP); both HO2. and OH. from 30% alkaline H2O2; while only HO2. from more alkaline SPT. RIV for OH. was maximum at 1min irradiation of acidic 30%H2O2 and 35%CP and minimum at 1min irradiation of neutral 30%H2O2. RIV for HO2.was maximum at 0min irradiation of alkaline 30%H2O2 and minimum at 2min irradiation of SPT. Conclusion: The bleaching agents having pH- neutral and acidic were always associated with OH.; weak alkaline with both OH. and HO2.; and strong alkaline with HO2. only. It is recommended to check the pH of the bleaching agents and if found acidic, should be made alkaline to minimize oxidative damage to enamel itself and then to pulp/periodontal tissues.

Abstract:

The `depmap` package facilitates access in the R environment to the data from the DepMap project, a multi-year collaborative effort by the Broad Institute and Wellcome Sanger Institute, mapping genetic and chemical dependencies and other molecular biological measurements of over 1700 cancer cell lines. The 'depmap' package formats this data to simply the use of popular R data analysis and visualizing tools such as 'dplyr' and 'ggplot2'. In addition, the 'depmap' package utilizes 'ExperimentHub', storing versions of the DepMap data accessible from the Cloud, which may be selectively downloaded, providing a reproducible research framework to support exploiting this data. This paper describes a workflow demonstrating how to access and visualize the DepMap data in R using this package.

Abstract:

O presente estudo avaliou o impacto de diferentes nveis de autocontrole e depleo do ego, na tentao de usar smartphones. A pesquisa foi composta por duas fases, sendo a primeira pesquisa exploratria de carter qualitativo e a segunda conclusiva causal, de carter quantitativo. Na fase exploratria foram feitas sete entrevistas, demonstrando que os indivduos viam o uso de celulares/smartphones como parte de suas vidas, mas tambm como uma tentao. Na segunda fase foi coletada uma amostra de 134 alunos de graduao para verificar a influncia do autocontrole e da depleo do ego no uso dos smartphones (tentao) durante uma simulao de teste (meta principal). Como resultado, foi verificado que quanto menor o autocontrole, mais os alunos utilizavam seus celulares durante um teste simulado. Quanto mais desgastados (depleo do ego), piores foram suas notas (questes corretas) nesta simulao. Ainda, foi verificado que o maior autocontrole capaz de minimizar os efeitos da depleo do ego sobre a quantidade de vezes que os alunos utilizaram o celular e, sobre a nota da prova simulada.

Abstract:

The relationship between ceramic roller kiln simulation model building parameters and temperature field uniformity is extremely difficult work. In this paper, DEPSO-CFD, a system integrated of an algorithm of hybrid particle swarm (PSO) with Differential Evolution (DE) operator, termed DEPSO, and computational fluid dynamics (CFD), is proposed to meet the demand. And with the help of the efficient parallel calculation, the ceramic roller kiln temperature field uniformity is mainly researched by using Fluent and DEPSO algorithm. It proves that the system is of high speed and of excellent parameter exploration capability, and the final computational example is got; thus parallel-DEPSO-CFD is of great academic value and significant applicable value.

Abstract:

This paper presents a hybrid differential evolution, particle swarm optimization and fuzzy c-means clustering algorithm called DEPSO-FCM for image segmentation. By the use of the differential evolution (DE) algorithm and particle swarm optimization to solve the FCM image segmentation influenced by the initial cluster centers and easily into a local optimum. Empirical results show that the proposed DEPSO-FCM has strong anti-noise ability; it can improve FCM and get better image segmentation results. In particular, for the HSI color image segmentation, the DEPSO-FCM can effectively solve the instability of FCM and the error split because of the singularity of the H component.

Abstract:

ABSTRACT Depo-Provera (Depo) is a long-acting progestational formulation that is a popular form of contraception for women. In animal models of sexually transmitted diseases, it is used to facilitate infection. Here we report that treatment with Depo, in a mouse model of genital herpes simplex virus type 2 (HSV-2), altered immune responses depending on the length of time that animals were exposed to Depo prior to immunization. Mice immunized intravaginally (i.vag.) with an attenuated strain (TK−) of HSV-2 following longer (15 days) exposure to Depo (Depo 15 group) failed to show protection when challenged with wild-type HSV-2. In contrast, mice that were immunized shortly after Depo treatment (5 days; Depo 5 group) were fully protected and showed no genital pathology after HSV-2 challenge. High viral titers were detected in the vaginal washes of the Depo 15 group up to 6 days postchallenge. In contrast, no viral shedding was observed beyond day 3 postchallenge in the Depo 5 group. Following i.vag. TK− immunization, high levels of gamma interferon (IFN-γ) were detected locally in vaginal washes of the Depo 5 group but not the Depo 15 group. After HSV-2 challenge, an early peak of IFN-γ in the Depo 5 group coincided with clearance of the virus. In Depo 15 animals IFN-γ was present throughout the 6 days postinfection. HSV-2-specific T-cell cytokine responses measured in the lymph node cells of Depo 5 TK−-immunized mice indicated a significantly higher Th1 response than that of Depo 15 TK−-immunized mice. The protection after HSV-2 challenge in the Depo 5 group correlated with increased local HSV-2 glycoprotein B (gB)-specific immunoglobulin G (IgG) and IgA responses seen in the vaginal secretions. The Depo 15 group had poor gB-specific antibody responses in the genital tract after HSV-2 challenge. These results indicate that longer exposure to Depo leads to poor innate and adaptive immune responses to HSV-2 that fail to protect mice from subsequent genital challenges.

Abstract:

Recent DepMap CRISPR-Cas9 single gene disruptions have identified genes more essential to proliferation in tissue culture. It would be valuable to translate these finding with measurements more practical for human tissues. Here we show that DepMap essential genes and other literature curated functional genes exhibit cell-specific preferential epigenetic conservation when DNA methylation measurements are compared between replicate cell lines and between intestinal crypts from the same individual. Culture experiments indicate that epigenetic drift accumulates through time with smaller differences in more functional genes. In NCI-60 cell lines, greater targeted gene conservation correlated with greater drug sensitivity. These studies indicate that two measurements separated in time allow normal or neoplastic cells to signal through conservation which human genes are more essential to their survival in vitro or in vivo.
