Variation in crystalline architectures through supramolecular interactions in copper(II) complexes with tridentate N2O donor Schiff bases

Three copper(II) complexes, [Cu(L-1)(H2O)(ClO4)]0.5H(2)O (1), [Cu(L-2)(H2O)(ClO4)]0.5H(2)O (2), and [Cu(L-2)(NCNC(OCH3)NH2)]ClO4 (3), where HL1=4-bromo-2-(-(quinolin-8-ylimino)methyl)phenol and HL2=1-(-(quinolin-8-ylimino)methyl)naphthalen-2-ol, have been prepared and characterized by elemental analysis, IR, UV-vis and fluorescence spectroscopy and single-crystal X-ray diffraction studies. The cop

Facile synthesis and polymerization of 2,6-difluoro-2’-sulfobenzophenone for aromatic proton conducting ionomers with pendant sulfobenzoyl groups

The lithium salt of 2,6-difluoro-2′-sulfobenzophenone was conveniently synthesized in one-pot by reacting 2,6-difluorophenyllithium with 2-sulfobenzoic acid cyclic anhydride in THF at −70 °C whereafter the product crystallized out of solution. A poly(arylene ether) and a poly(arylene sulfide) were prepared by polycondensation reactions to demonstrate the reactivity and efficacy of this new monomer

Exploiting cell metabolism for biocatalytic whole-cell transamination by recombinant Saccharomyces cerevisiae.

The potential of Saccharomyces cerevisiae for biocatalytic whole-cell transamination was investigated using the kinetic resolution of racemic 1-phenylethylamine (1-PEA) to (R)-1-PEA as a model reaction. As native yeast do not possess any ω-transaminase activity for the reaction, a recombinant yeast biocatalyst was constructed by overexpressing the gene coding for vanillin aminotransferase from Cap

Slope distribution in front-back asymmetric stochastic Lagrange time waves

The stochastic Lagrange wave model is a realistic alternative to the Gaussian linear wave model, which has been successfully used in ocean engineering for more than half a century. This paper presents the slope distributions and other characteristic distributions at level crossings for asymmetric Lagrange time waves, i.e. what can be observed at a fixed measuring station, thereby extending result

Accurate Detection of Changes in Disease Activity in Primary Sjogren's Syndrome by the European League Against Rheumatism Sjogren's Syndrome Disease Activity Index

Objective. To assess and compare the sensitivity to change of the European League Against Rheumatism Sjogren's Syndrome Disease Activity Index (ESSDAI) with that of other primary Sjogren's syndrome (SS) disease activity indexes. Methods. We abstracted 96 patient profiles, including data on 3 successive visits (visits 1-3), from the medical charts of patients with primary SS. Patient profiles were

Management of acquired aplastic anemia in children

The diagnosis of aplastic anemia in children requires exclusion of a variety of inherited or acquired BM failure syndromes with similar phenotypes. An efficient diagnostic plan is important because time from diagnosis to 'final' treatment is directly related to outcome regardless of the therapeutic option chosen. The gold standard of therapy remains hematopoietic SCT with a graft of BM cells for t

Surrogate measures of insulin sensitivity vs the hyperinsulinaemic-euglycaemic clamp: a meta-analysis

Aims/hypothesis We aimed to identify which surrogate index of insulin sensitivity has the strongest correlation with the reference measurement, the hyperinsulinaemic-euglycaemic clamp (HEC), to determine which surrogate measure should be recommended for use in large-scale studies. Methods A literature search (1979-2012) was conducted to retrieve all articles reporting bivariate correlations betwee

Classification of Amino Acid Substitutions in Mismatch Repair Proteins Using PON-MMR2.

Variations in mismatch repair (MMR) system genes are causative of Lynch syndrome and other cancers. Thousands of variants have been identified in MMR genes, but the clinical relevance is known for only a small proportion. Recently, the InSiGHT group classified 2,360 MMR variants into five classes. One-third of variants, majority of which is nonsynonymous variants, remain to be of uncertain clinica

Increased Heterogeneity of Bone Matrix Mineralization in Pediatric Patients Prone to Fractures: A Biopsy Study

Idiopathic osteoporosis (IOP) in children is characterized by fragility fractures and/or low bone mineral density in otherwise healthy individuals. The aim of the present work was to measure bone mineralization density distribution (BMDD) based on quantitative backscattered electron imaging (qBEI) in children with suspected IOP. Entire cross-sectional areas of transiliac bone biopsy samples from c

Validation of standard ASTM F2732 and comparison with ISO 11079 with respect to comfort temperature ratings for cold protective clothing

American standard ASTM F2732 estimates the lowest environmental temperature for thermal comfort for cold weather protective clothing. International standard ISO 11079 serves the same purpose but expresses cold stress in terms of required clothing insulation for a given cold climate. The objective of this study was to validate and compare the temperature ratings using human subject tests at two lev

Changes in phenolic antioxidants during chuno production (traditional Andean freeze and sun-dried potato)

Total antioxidant capacity (TAC), total phenolic compounds (TPH), total flavonoids (TF) and the amounts of individual phenolic compounds were assessed in Bolivian potato cultivars (various Solanum species) before, during and after the traditional freezing and sun-drying of potatoes known as chunos. The TAC of chunos ranged from 0.4 to 2.7 mu mol Trolox equivalents/g dry matter using 2,2'-azino-bis

Parkinson's disease: The non-motor issues

Non-motor symptoms (NMS) of Parkinson's disease remain the most under-appreciated and under-researched when taken as a whole. Data is emerging that it is the "totaL" burden of NMS that is the major determinant of quality of life not a single NMS such as depression for instance. Only recently validated tools such as the NMSQuest which empowers patients to declare NMS and the NMS scale, the SCOPA sc

My Space: governing individuals' carbon emissions

This paper examines the recent growth in projects designed to enable individuals to 'do their bit' in the struggle to limit climate change. It discusses them in relation to a long-standing critique of trends towards individualisation amongst environmentalists. It suggests that this critique misses the complex way that subjects are produced by these practices and proposes to analyse subjectificatio

Controls of spatial and temporal variability in CH4 flux in a high arctic fen over three years

The aim of this study was to establish the main drivers of the spatial variability in growing season CH4 flux within an arctic wetland ecosystem. During 3 years (2011-2013) we measured CH4 flux and potential drivers, e.g., CO2 fluxes (net ecosystem exchange (NEE), gross primary productivity (GPP) and ecosystem respiration), temperature, water table depth, pore-water concentration of organic acids

Improvements to an Empirical Parameterization of Heterogeneous Ice Nucleation and Its Comparison with Observations

A framework for an empirical parameterization (EP) of heterogeneous nucleation of ice crystals by multiple species of aerosol material in clouds was proposed in a 2008 paper by the authors. The present paper reports improvements to specification of a few of its empirical parameters. These include temperatures for onset of freezing, baseline surface areas of aerosol observed in field campaigns over

Cognitive Function in Young Men and the Later Risk of Fractures

Dementia has been associated with an increased risk of fractures. These associations may be explained by an impaired cognitive function, as well as comorbid illness and toxic reaction from drugs. To investigate whether cognitive function in young, healthy individuals already affects the risk of fractures, overall cognitive function scores were calculated from four cognitive tests accomplished duri
