The syntheses of new nitrogen-oxygen donor macrocycles and liquid membrane transport of alkali cations

AbstractFive new nitrogen-oxygen mixed donor macrocycles have been prepared by condensation of N,N-bis[2-(2-formylphenoxy)ethyl]-4-methylphenylsulphonamide with diamino compounds, followed by a one-pot reduction of the intermediate bis-Schiff base. The transport of alkali metal ions across a liquid membrane using these macrocycles as ion carrier was studied, and the results show that the rates of cation transport are affected by the size of macrocycle.

Studies on the syntheses of hydroxy-bearing benzo-azacrown ethers and their complexing behaviour

AbstractFive new hydroxy-bearing dibenzoazacrown ethers were synthesized by a convenient route. Reaction of salicyladehyde with epichlorohydrin gave l,3-bis(2-formylphenoxy)-2-propanol, which condensed with diamino compounds followed by a one pot reduction of the corresponding bis-imine derivatives without isolation to afford the hydroxy-bearing dibenzoazacrown ethers. All of the ligands were identified by EA, IR and NMR. Some transition metal complexes were prepared and characterized by elemental analysis, IR and molar conductance. The transport of alkali metal cations across a liquid membrane by using these ligands as ion carrier was also studied.

Systemic HypertensionRelation of left ventricular hypertrophy and geometry to asymptomatic cerebrovascular damage in essential hypertension☆

AbstractIncreased left ventricular (LV) mass and abnormal geometry have a powerful prognostic value for cardiovascular morbidity and mortality including stroke. However, there have been no studies on the association between LV hypertrophy and preclinical brain damage in essential hypertensive patients. In the present study, we investigated the relation between LV hypertrophy and asymptomatic cerebrovascular damage identified by magnetic resonance imaging in 150 essential hypertensive patients, with an emphasis on LV geometry. Patients were divided into the following 4 groups according to their LV mass index and relative wall thickness; normal ventricular geometry (n = 50), concentric remodeling (n = 22), eccentric hypertrophy (n = 44), and concentric LV hypertrophy (n = 34). Lacunar lesions and leukoaraiosis were evaluated. The prevalence of lacunae was significantly higher in patients with LV remodeling than in patients with normal LV (chi-square 19.6, p = 0.0002). The number of lacunae was significantly higher in patients with LV hypertrophy than in patients with normal LV or concentric remodeling (F [3,146] = 8.03, p<0.0001). The severity of leukoaraiosis was also significantly greater in patients with LV hypertrophy than in patients with a normal left ventricle (chi-square 14.5, p = 0.02). Stepwise regression analysis confirmed that LV mass index and relative wall thickness, in addition to age and systolic blood pressure, were independent predictors for asymptomatic cerebrovascular damage, even in the absence of neurologic abnormalities. In hypertensive patients, LV hypertrophy, and especially concentric LV hypertrophy, provides important prognostic information on the presence of preclinical brain damage.

The ubiquitin specific protease-4 (USP4) interacts with the S9/Rpn6 subunit of the proteasome

AbstractThe proteasome is the major non-lysosomal proteolytic machine in cells that, through degradation of ubiquitylated substrates, regulates virtually all cellular functions. Numerous accessory proteins influence the activity of the proteasome by recruiting or deubiquitylating proteasomal substrates, or by maintaining the integrity of the complex. Here we show that the ubiquitin specific protease (USP)-4, a deubiquitylating enzyme with specificity for both Lys48 and Lys63 ubiquitin chains, interacts with the S9/Rpn6 subunit of the proteasome via an internal ubiquitin-like (UBL) domain. S9/Rpn6 acts as a molecular clamp that holds together the proteasomal core and regulatory sub-complexes. Thus, the interaction with USP4 may regulate the structure and function of the proteasome or the turnover of specific proteasomal substrates.

Surface functionalization of vertically-aligned carbon nanotube forests by radio-frequency Ar/O2 plasma

AbstractVertically-aligned carbon nanotube (CNT) forests were modified using radio-frequency Ar/O2 plasma. The effect of plasma parameters on surface morphology, atomic composition and structure of CNT forests were studied. Functionalized CNT forests preserved vertical alignment and showed dramatic change in surface morphology, and bundle-like patterns were observed from scanning electron microscopy examination. X-ray photoelectron spectroscopy and Raman analyses reveal that the amount of sp2-hybridized graphite-like carbon bond in CNTs decreased significantly and oxygen-containing functionalities like C–O and O–CO groups were introduced after treatment. And the functionalization occurred exclusively on outer surface of CNT forests. Ar/O2 plasma was found to be more efficient than pure Ar plasma for oxygen functionalization.

Gas transport in vertically-aligned carbon nanotube/parylene composite membranes

AbstractVertically-aligned carbon nanotube (VACNT) composite membranes were fabricated by impregnating carbon nanotube (CNT) forests with poly-para-xylylene (parylene-C) through room-temperature chemical vapor deposition (CVD). Transport properties of diverse gases through the CNT/parylene membranes were investigated. The gas permeances scaled inversely with their molecular weights in accordance with Knudsen model and the value of permeance was about 30 times higher than that predicted by the Knudsen diffusion kinetics, which was attributed to the atomically smooth interiors of CNTs. In addition, the gas permeance values in this work were higher than those reported for other VACNT membranes, due to the smaller membrane thickness and good crystallinity of the CNTs.

Full PapersA Series of Mutations in the D-MEF2 Transcription Factor Reveal Multiple Functions in Larval and Adult Myogenesis in Drosophila

AbstractThe D-mef2 gene encodes a MADS domain transcription factor expressed in differentiated muscles and their precursors in the Drosophila embryo. Embryos deficient for D-MEF2 protein due to a deletion of upstream transcriptional control sequences fail to form muscle, suggesting that the gene is required for muscle cell differentiation. To directly demonstrate a role for D-mef2 in embryonic myogenesis, we isolated gene mutants containing EMS-induced point mutations, characterized the effects of these mutations on D-MEF2 protein stability and nuclear localization, and analyzed the resulting muscle phenotypes. Our results show that in the somatic muscle lineage, D-mef2 is required for both the formation and patterning of body wall muscle. In the absence of somatic myogenesis, there is extensive apoptosis among the myoblast cell population. In contrast, in the cardiac muscle lineage, morphogenesis of the dorsal vessel occurs normally but the three myosin subunit genes are not expressed. Mutant embryos also exhibit an abnormal midgut morphology, which correlates with the absence of αPS2 integrin gene expression and muscle-specific enhancer function, suggesting that D-mef2 regulates the inflated locus which encodes this integrin subunit. D-MEF2 is also expressed in adepithelial cells and rare D-mef2 transheterozygous mutant adults fail to fly, consistent with defects observed in the indirect flight muscles. These results demonstrate that the D-mef2 gene has multiple functions in myogenesis and tissue morphogenesis during Drosophila development.

Effective watermarking scheme in the encrypted domain for buyer–seller watermarking protocol

AbstractIn most watermarking schemes for copyright protection, a seller usually embeds a watermark in multimedia content to identify a buyer. When an unauthorized copy is found by the seller, the traitor’s identity can be traced by the embedded watermark. However, it incurs both repudiation issue and framing issue. To solve these problems, some buyer–seller watermarking protocols have been proposed based on watermarking scheme in the encrypted domain. In this paper, an enhanced watermarking scheme is presented. Compared with Solanki et al.’s scheme, the enhanced scheme increases effective watermarking capacity, avoids additional overhead and overcomes an inherent flaw that watermarking capacity depends on the probability distribution of input watermark sequence. Based on the security requirements of buyer–seller watermarking protocols, a new watermarking scheme in the encrypted domain with flexible watermarking capacity is proposed. It improves the robustness of watermark sequence against image compressions and enables image tampering detection. Watermark extraction is blind, which employs the same threshold criterion and secret keys as watermark embedding. Experimental results demonstrate that the enhanced watermarking scheme eliminates the drawbacks of Solanki et al.’s scheme and that the proposed watermarking scheme in the encrypted domain outperforms Kuribayashi and Tanaka’s scheme.
