Hydrogen is considered as an environmental friendly energy carrier because it generates no pollution. Chlorides are promising catalyst for the hydrogen desorption in sodium alanate. All reactions and operations were performed under argon atmosphere in glove box. Crystalline NaAlH 4 and catalyst TiCl 3 , Nb 2 O 5 PbCl 2 and CeCl 3 were mixed in a ratio of (1, 2) wt%. Due to the air sensitivity of the samples they were covered with a kapton tape layer to minimize any contamination for characterization purpose. Structural characterizations and phase compositions of the samples were studied by XRD. The hydrogen storage capacity is measured by seivert type apparatus. Amount of desorbed hydrogen was found to be 3.6 wt % to 5.5 wt% at 250 o C with different type of catalyst. In the present work effect of doping of TiCl 3 , Nb 2 O 5 PbCl 2 and CeCl 3 catalysis in NaAlH 4 are investigated to understand the hydrogen desorption kinetics. It is concluded that enhanced storage capacity of NaAlH 4 can be achieved due to various catalysts with reduction in temperature 285 o C-250 o C for desorption.

Dissolved carbohydrate obtained from 1-butyl-3-methylimidazolium chloride ([BMIM]Cl) pretreated sago waste was saccharified by Amberlyst 15 (A15) to study the kinetics of the ionic liquid-mediated solid acid saccharification of the lignocellulosic biomass. Besides the kinetics of both reducing sugars production and reducing sugars degradation reactions, emphasis was given to the recovery and reusability of the ionic liquid and solid acid catalyst. The hydrolysis reaction follows a first order sugars production-first order sugars degradation reaction that agreed well with the generalized Saeman kinetic model. Both the rates of reducing sugars production and degradation varied with temperature and catalyst loading. Higher temperature and catalyst loading promoted the rates of sugars production reaction more than the rate of degradation reaction. This is evident from the relatively larger rate constant of sugars production (k 1 ) than the rate constant of degradation (k 2 ). The activation energy for sugars production and degradation was 125.1kJmol -1 and 60.8kJmol -1 respectively. These values are lower than the literature reported values for sulfuric acid-catalyzed saccharification confirming its employment suitability for reducing sugars production. The good recovery of [BMIM]Cl and good reusability of A15 further substantiated the feasibility of the process. The recovery of ionic liquid was improved by employing a multiple step aqueous biphasic system in this study. Approximately 60% of the ionic liquid was recovered by 3-step aqueous biphasic system. This finding is on par with the reported literatures using aqueous biphasic system to recover ionic liquid. Equally robust, the solid acid catalyst regained its saccharification performance after regeneration for a total of three cycles.

Chloride intracellular channel-4 (CLIC4) is not required for embryonic collateral arteriole formation in the brain but is required for perinatal collateral maturation. Vegfa overexpression in CLIC4-deficient mice partially rescues deficits in perinatal collateral mural cell investment, and fully rescues aberrant perinatal collateral pruning and enlarged infarct volume after stroke in adults . The number and diameter of native collaterals in tissues of healthy mice vary widely, resulting in large differences in tissue injury in occlusive diseases. Recent studies suggest similar variation may exist in humans. Collateral variation in mice is determined by genetic background-dependent differences in embryonic collateral formation, by variation in maturation of the nascent collaterals, and by environmental factors such as aging that cause collateral rarefaction in the adult. Recently, formation of the collateral circulation in the brain was found to involve a unique VEGF-A-dependent #x201C;arteriolar #x201D; angiogenic sprouting-like mechanism. Elsewhere, chloride intracellular protein 4 (CLIC4) was implicated but not investigated directly, prompting the present study. Deletion of Clic4 had no effect on embryonic collaterogenesis. However, during collateral maturation from embryonic day 18.5 to postnatal day 7, reduced mural cell investment was observed and excessive pruning of collaterals occurred. Growth in collateral diameter was reduced. This resulted in 50% fewer collaterals of smaller diameter in the adult and thus larger infarct volume after middle cerebral artery occlusion. During collateral maturation, CLIC4 deficiency resulted in reduced expression of Vegfr2 , Vegfr1 , Vegfc , and mural cell markers, but not notch-pathway genes. Overexpression of VEGF-A in Clic4 #x2212;/ #x2212; mice had no effect on collaterogenesis, but rescued the above defects in collateral maturation by preventing mural cell loss and collateral pruning, thus restoring collateral number and diameter and reducing stroke severity in the adult. CLIC4 is not required for collaterogenesis but is essential for perinatal maturation of nascent collaterals through a mechanism that supports VEGF signaling.

Combined phylogenetic and HPLC-MS-based natural products dereplication methods aimed at identifying cyanobacterial collections containing the potent cytotoxins largazole, dolastatin 10, and symplostatin 1 were developed. The profiling of the phylogeny, chemical space, and antiproliferative activity of cyanobacterial collections served to streamline the prioritization of samples for the discovery of new secondary metabolites. The dereplication methods highlighted the biosynthetic potential and combinatorial pharmacology employed by marine cyanobacteria. We found that largazole was always coproduced with dolastatin 10 or with symplostatin 1 and consequently tested combinations of these agents against colon cancer cells. Combinatorial regimens of largazole and dolastatin 10 aimed at curbing the growth of HCT116 cancer cells showed cooperative activity. Graphic Abstract ACS Electronic Supporting Info

The mechanical properties of alpha;-Ti are greatly affected by the presence of oxygen impurities. Here we focus on the interaction of oxygen with prismatic faults and oxygen diffusion barriers in alpha;-Ti using a multiscale quantum mechanics/molecular mechanics approach. We show that a one-sixth monolayer of oxygen addition increases the Peierls stress 4-fold and reduces the dislocation core width by 18%. The calculated hardening effect due to oxygen and the oxygen diffusion barriers are consistent with experiments.

초록보기원문보기 >
Digestive tract tumors are among the most common and deadliest malignancies worldwide, mainly due to late diagnosis and lack of efficient therapeutics. Current treatments essentially rely on surgery associated with (neo)adjuvant chemotherapy agents. Despite an upfront response, conventional drugs often fail to eliminate highly aggressive clones endowed with chemoresistant properties, which are responsible for tumor recurrence and disease dissemination. Synthetic drugs also present severe adverse systemic effects, hampering the administration of biologically effective dosages. Nanoencapsulation of chemotherapeutic agents within biocompatible polymeric or lipid matrices holds great potential to improve the pharmacokinetics and efficacy of conventional chemotherapy while reducing systemic toxicity. Tagging nanoparticle surfaces with specific ligands for cancer cells, namely monoclonal antibodies or antibody fragments, has provided means to target more aggressive clones, further improving the selectivity and efficacy of nanodelivery vehicles. In fact, over the past twenty years, significant research has translated into a wide array of guided nanoparticles, providing the molecular background for a new generation of intelligent and more effective anti-cancer agents. Attempting to bring awareness among the medical community to emerging targeted nanopharmaceuticals and foster advances in the field, we have conducted a systematic review about this matter. Emphasis was set on ongoing preclinical and clinical trials for liver, colorectal, gastric and pancreatic cancers. To the best of our knowledge this is the first systematic and integrated overview on this field. Using a specific query, 433 abstracts were gathered and narrowed to 47 manuscripts when matched against inclusion/exclusion criteria. All studies showed that active targeting improves the effectiveness of the nanodrugs alone, while lowering its side effects. The main focus has been on hepatocarcinomas, mainly by exploring glycans as homing molecules. Other ligands such as peptides/small proteins and antibodies/antibody fragments, with affinity to either tumor vasculature or tumor cells, have also been widely and successfully applied to guide nanodrugs to gastrointestinal carcinomas. Conversely, few solutions have been presented for pancreatic tumors. To this date only three nanocomplexes have progressed beyond pre-clinical stages: i) PK2, a galactosamine-functionalized polymeric-DOX formulation for hepatocarcinomas; ii) MCC-465, an anti-(myosin heavy chain a) immunoliposome for advanced stage metastatic solid tumors; and iii) MBP-426, a transferrin-liposome-oxaliplatin conjugate, also for advanced stage tumors. Still, none has been approved for clinical use. However, based on the high amount of pre-clinical studies showing enthusiastic results, the number of clinical trials is expected to increase in the near future. A more profound understanding about the molecular nature of chemoresistant clones and cancer stem cell biology will also contribute to boost the field of guided nanopharmacology towards more effective solutions.

Covering: up to 2014 Various marine natural products that target cytoskeletal proteins have been discovered. A few of these compounds have recently been shown to induce or inhibit protein ndash;protein interactions. Lobophorolide, an actin filament-disrupting macrolide, binds to actin with a unique 2 : 2 stoichiometry in which two lobophorolide molecules cooperate to stabilize an actin dimer. Adociasulfates, merotriterpenoid derivatives, inhibit microtubule-stimulated ATPase activity of a motor protein kinesin by blocking both the binding of microtubules and the processive motion of kinesin along microtubules. The antitumor macrolide aplyronine A synergistically binds to tubulin in association with actin, and prevents spindle formation and mitosis. In this highlight, we address recent chemical biology studies on these mechanistically-attractive marine natural products. These findings may be useful for the design and development of new pharmacological tools and therapeutic agents.

A segment-based activity coefficient model is developed through the Universal Quasichemical (UNIQUAC-SAC) approach and is applied for vapor ndash;liquid and solid ndash;liquid equilibrium calculations. We incorporated the conceptual segment approach of the NRTL-SAC activity coefficient model with modification of binary interaction parameters for the conceptual segments. The conceptual segments are represented by n -hexane, dimethyl sulfoxide, nitromethane, and water as hydrophobic, polar attractive, polar repulsive, and hydrophilic, respectively. The UNIQUAC-SAC molecular parameters are obtained for 82 common solvents, 62 of which are common solvents in the pharmaceutical industry. The UNIQUAC-SAC and NRTL-SAC models are employed to compute the vapor ndash;liquid equilibrium of binary, ternary, and quaternary systems. In most cases, the UNIQUAC-SAC model gives a better prediction than the NERL-SAC model. Moreover, the UNIQUAC-SAC model is extended to modeling the solubility of organic nonelectrolyte solute in common solvents. Finally, using the UNIQUAC-SAC and NRTL-SAC models, the solubility data of several pharmaceutical solutes is calculated in one- and two-solvent systems and compared with experimental results.

Apocalypse as a literary genre, as well as a political and religious agenda, has been criticized by writers such as Lee Quinby and Katherine Keller for its formula, which tends toward punishment for transgression and salvation of an elect. These same writers critique postapocalypse for its propensity for nihilism and portrayal of a human species #x2018;beyond redemption #x2019;. But perhaps it is precisely this refusal to redeem that endows postapocalypse with dangerous possibilities. The postapocalypse does not have to be considered (and subsequently neutralized) via the same moral underpinnings that structure apocalypse. This paper frames postapocalypse not as a literature of pessimism or warning but as a radical context to explore dangerous possibilities without rehearsing apocalypse #x2019;s characteristic damnation, salvation and enforcement of a horizon of revelation that simultaneously works to obliterate aberrant possibilities. In order to explore these claims, the process of thinking beyond revelation in apocalypse is defined here as #x2018;the postapocalyptic imagination #x2019;. Its expressions are found in postapocalyptic texts, but also in other kinds of texts that respond to, and in some cases resist, the teleological drive of late capitalist narratives of endless progress. The postapocalyptic world is host to mutations, amalgamations and strange appropriations of forms and ideas left in the wreckage beyond the end. It is the task of the postapocalyptic imagination to explore what possibilities these #x2018;abominations #x2019; might offer. This paper considers the motifs, characters and settings of postapocalyptic texts, alongside some of the anxieties and critiques they express.

Allergic rhinitis (AR) is the most common chronic disease in childhood and yet is often ignored and/or misdiagnosed. It can present as part of the atopic spectrum of disorders and can affect not only the nose but also its connections, manifesting often with a multiplicity of symptoms, sometimes atypical. If uncontrolled or inappropriately treated, AR can severely impair quality of life for children and their families. Growing evidence of its association with bronchial asthma is emerging: both as a risk factor for asthma development and a major factor in exacerbations. This article aims to give advice about diagnosis and management of this important, common condition to generalists who will encounter it frequently in their clinical practice. The use of evidence-based guidelines for AR therapy results in improved disease control. Current management is based on avoidance of triggering allergen(s), non-sedative anti-histamines for mild disease, and use of non-systemically bioavailable nasal steroids for moderate/severe disease. The use of an intranasal combined preparation of fluticasone propionate and azelastine for those unresponsive to these measures is under investigation. Allergen-specific immunotherapy, currently recommended for severe cases, is the only treatment modality potentially able to alter long term not only disease severity, but also progression. Immunotherapy is often unavailable to deserving patients and concern regarding risk/benefit and acceptability can hamper its use in children. Evidence on efficacy and safety of the more child-friendly sublingual route of administration is emerging, however further well-designed paediatric studies are needed. Education of patients, carers and of practitioners in the nature of AR, the possible need for long term concordance with therapy and the optimal use of this is a vital part of disease management.

A low off-state current of 1.6x10 -14 A/ mu;m and a small subthreshold gate swing of 152mV/decade were achieved in a novel thin film transistor using a c-axis crystallized InGaZnO semiconductor that could be obtained at a low substrate temperature range of 150 o C. From experimental results, we found that the lowered off-state current is mainly attributed to the formation of rich Ga-O bonds to reduce oxygen vacancies, and the c-axis crystallized structure of IGZO to increase the potential barrier on the source side due to the increase of local trap states at the grain boundary.

There is an increasing interest in the role of spirituality on the experience of health, wellness and illness, as well as the role of spiritual practice in health care provision. For pregnancy and childbirth, this focus has tended to concentrate on hospital birth settings and care, and religious forms of spirituality. The blessingway ceremony can be described as an alternative baby shower, popular with home-birthing women. Its focus is woman-centred and draws on the power of ritual to evoke a spiritual experience for the pregnant host and her guests. This spirituality is experienced as a strong connection between women, their relationship with #039;nature #039;, and forged via the nostalgic imagination of women through time and space. This article will draw on data obtained in 2010 during doctoral fieldwork with 52 home-birthing women across eastern Australia and will examine the blessingway ceremony and its significance as a site of potential spiritual empowerment for pregnant and birthing women.

Understanding how students learn in the undergraduate chemistry teaching laboratory is an essential component to developing evidence-based laboratory curricula. The Meaningful Learning in the Laboratory Instrument (MLLI) was developed to measure students rsquo; cognitive and affective expectations and experiences for learning in the chemistry laboratory. Previous cross-sectional studies in both general and organic chemistry laboratory courses have shown trends where cognitive expectations go unfulfilled, and affective expectations and experiences are diverse among all students. On the basis of these previous findings, a longitudinal study was carried out to explore how students rsquo; ideas about laboratory learning change over two years of chemistry laboratory instruction. The data were analyzed using multiple visualizations, inferential statistics, and cluster analysis. Findings from this study supported previous findings from the cross-sectional studies. In addition, it was found that students ldquo;reset rdquo; their expectations for organic chemistry laboratory, meaning they indicated high expectations for learning despite unfulfilled expectations in their general chemistry laboratory. Further findings and their implications are discussed within the context of Novak rsquo;s theory of meaningful learning. Graphic Abstract ACS Electronic Supporting Info

An epoxy-functional polysiloxane (EPM) was employed for improving the performance of flame-retarded poly(butylene terephthalate)/aluminum diethylphosphinate (PBT/AlPi) composites. The effect was investigated by UL-94 test, limiting oxygen index, mechanical test, torque rheometer measurement, differential scanning calorimetry, dynamic mechanical analysis, and heat distortion temperature. An obvious increase in torque evolution of the PBT/AlPi composite during processing was associated with chain-extending, branching, and cross-linking reaction by the combination of EPM. The addition of 0.6 wt% EPM remarkably enhanced not only the mechanical properties but also the flame retardancy and heat resistance of the PBT/AlPi composite. A high-performance PBT/AlPi composite was developed by virtue of EPM.
