Abstract

In this study, microencapsulation of thermochromic systems containing fluoran dye was aimed. For this purpose, thermochromic systems containing fluoran dye, Bisphenol A and 1-tetradecanol were microencapsulated with poly(methyl methacrylate) using emulsion polymerization method. Thermal properties and thermal stability of the microcapsules were investigated by differential scanning calorimetry (DSC) and thermal gravimetric (TG) analyzes. The thermo-regulation property of the microcapsules was tested by T-history analysis consisting of temperature sensor and data logger. The temperature-sensitive reversible discoloration properties of the microcapsules were determined by photographs taken at temperatures above and below the activation temperature. According to DSC results, microcapsules had latent heat storage in the range of 152.6-185.8 J/g. It was determined that the microcapsules, which were colored below the activation temperature, lost their color above the activation temperature and exhibited reversible color change property depending on change in temperature. From TG analysis results, it was determined that microcapsules had sufficient thermal resistance for textile applications. © Chamber of Textile Engineers.

Abstract

This study focused on fabrication of the thermochromic microcapsules and their application to the cotton fabric. In this study, thermochromic systems composed of crystal violet lactone, bisphenol A, and 1-tetradecanol were prepared and microencapsulated by emulsion polymerization method in poly(methyl methacrylate-co-ethylene glycol dimethacrylate-co-glycidyl methacrylate) wall. The microcapsules were analyzed by Fourier transform infrared spectroscopy, scanning electron microscope, transmission electron microscope, differential scanning calorimetry, and thermogravimetric analysis. Their thermoregulating property was tested by T-history test. The results revealed that microcapsules with smooth surfaces, core–shell structured, and spherical shape were successfully produced. The latent heat storage capacity of the microcapsules decreased from 202 J g?1 to 167 J g?1 when their shell/core ratio changed from 0.5/1 to 2/1. Microcapsules were adequately had sufficient thermal resistance to the temperatures they will encounter during their application to textile products and their usage. According to the UV–visible spectroscopy analysis and color measurements, the microcapsules exhibited reversible color change from blue to colorless and vice versa. Besides, the microcapsule impregnated fabric was able to absorb latent heat energy of 21.79 J g?1 at around 35 °C and had cooling effect. According to the colorimetric parameters, the fabric was at blue color at room temperature and became colorless when heated to the temperature above the melting point of thermochromic system. © 2019 Wiley Periodicals, Inc.

Abstract

The chromosome 9p21 amyotrophic lateral sclerosis-frontotemporal dementia (ALS-FTD) locus contains one of the last major unidentified autosomal-dominant genes underlying these common neurodegenerative diseases. We have previously shown that a founder haplotype, covering the MOBKL2b, IFNK, and C9ORF72 genes, is present in the majority of cases linked to this region. Here we show that there is a large hexanucleotide (GGGGCC) repeat expansion in the first intron of C9ORF72 on the affected haplotype. This repeat expansion segregates perfectly with disease in the Finnish population, underlying 46.0% of familial ALS and 21.1% of sporadic ALS in that population. Taken together with the D90A SOD1 mutation, 87% of familial ALS in Finland is now explained by a simple monogenic cause. The repeat expansion is also present in one-third of familial ALS cases of outbred European descent, making it the most common genetic cause of these fatal neurodegenerative diseases identified to date. © 2011 Elsevier Inc.

Abstract

A major use of the 1000 Genomes Project (1000GP) data is genotype imputation in genome-wide association studies (GWAS). Here we develop a method to estimate haplotypes from low-coverage sequencing data that can take advantage of single-nucleotide polymorphism (SNP) microarray genotypes on the same samples. First the SNP array data are phased to build a backbone (or 'scaffold') of haplotypes across each chromosome. We then phase the sequence data 'onto' this haplotype scaffold. This approach can take advantage of relatedness between sequenced and non-sequenced samples to improve accuracy. We use this method to create a new 1000GP haplotype reference set for use by the human genetic community. Using a set of validation genotypes at SNP and bi-allelic indels we show that these haplotypes have lower genotype discordance and improved imputation performance into downstream GWAS samples, especially at low-frequency variants. © 2014 Macmillan Publishers Limited.

Abstract

By characterizing the geographic and functional spectrum of human genetic variation, the 1000 Genomes Project aims to build a resource to help to understand the genetic contribution to disease. Here we describe the genomes of 1,092 individuals from 14 populations, constructed using a combination of low-coverage whole-genome and exome sequencing. By developing methods to integrate information across several algorithms and diverse data sources, we provide a validated haplotype map of 38 million single nucleotide polymorphisms, 1.4 million short insertions and deletions, and more than 14,000 larger deletions. We show that individuals from different populations carry different profiles of rare and common variants, and that low-frequency variants show substantial geographic differentiation, which is further increased by the action of purifying selection. We show that evolutionary conservation and coding consequence are key determinants of the strength of purifying selection, that rare-variant load varies substantially across biological pathways, and that each individual contains hundreds of rare non-coding variants at conserved sites, such as motif-disrupting changes in transcription-factor-binding sites. This resource, which captures up to 98% of accessible single nucleotide polymorphisms at a frequency of 1% in related populations, enables analysis of common and low-frequency variants in individuals from diverse, including admixed, populations., National Institutes of Health (U.S.) (Grant RC2HL102925), National Institutes of Health (U.S.) (Grant U54HG3067)

Abstract

WOS: 000182126000015 The temperature dependence of the electrical conductivity, microstructure and crystal structure properties of the [Co,(L)L'(dioxane)(2)(NO3)(2)](NO3)(2) complex was investigated. The X-ray diffraction showed that the [Co,(L)L'(dioxane)(2) (NO3)(2)](NO3)(2) has a triclinic structure. Temperature dependence of the conductivity curve of the complex exhibited two conduction regions, and while increase of conductivity with temperature in the first region is of hopping conduction which takes place in localized states, the conduction in the second region is of Arrhenius-type. These conduction mechanisms are related to intermolecular and intramolecular conduction progresses. The electrical conductivity of the [Co-2(L)L'(dioxane)(2)(NO3)(2)](NO3)(2) complex was 2.57 x 10(-7) (S/cm) at room temperature with activation energy of 0.46 eV which showed semiconductivity behavior.

Abstract

WOS: 000318758500013 Six new CuL1 (L-1 = 4-bromo-2-(1H-imidazo[4,5-f][1,10]phenanthroline-2-yl)phenol), CoL1, NiL1, CuL2 (L-2 = 2-(1H-imidazo[4,5-f] [1,10]phenanthroline-2-yl)-5-methoxyphenol), CoL2 and NiL2 complexes were synthesized. L-1 and L-2 ligands were prepared by the condensation of 1,10-phenanthroline-5,6-dione with 5-bromosalicylaldehyde and 2-hydroxy-4-methoxybenzaldehyde, respectively. The structures of the compounds were determined by elemental analyses, IR, UV-visible, H-1-NMR, TGA, magnetic susceptibilities and molar conductance measurements. It is observed that the synthesized complexes have tetragonal and distorted square pyramidal geometrical structures. Antibacterial activity of the ligands and their metal complexes were tested against selected bacteria by disc diffusion method.

Abstract

In this study, it was carried out the development of a poly(ethylene glycol)/cellulose phase change reactive composite as latent heat storage material for cooling application and determination of its thermal stability. Poly(ethylene glycol) (PEG) was grafted onto a cellulose backbone as solid–solid phase change material. The change in the surface morphology of the PEG1000 was studied by using a polarised optical microscopy (POM) instrument. Thermal analysis and thermal stability upon usage of the phase change composite material were performed by using a differential scanning calorimeter (DSC) instrument. The chemical analysis of the PCM composite was carried out by using a fourier transform infrared spectroscopy (FTIR) instrument. Phase change composite melted and crystallized 10 times to determine the thermal stability. The PEG1000 grafted cellulose phase change composite before 10 times thermal cycling absorbed 78.6 J/g of heat at 7.7 °C and released 74.4 J/g at - 5.4 °C whereas the PEG1000 grafted cellulose phase change composite after 10 times thermal cycling absorbed 92.7 J/g of heat at 8.3 °C and released 83.2 J/g at 1 °C during melting and freezing respectively. It was observed that Cp of the PEG1000 grafted cellulose sample was decreased compared to Cp of the pristine PEG1000. There was a considerable difference between crystal structures of pristine PEG1000 and PEG1000 grafted cellulose phase change composite. The disappearance of diisocyanate peak of TDI observed at 2228.34 cm -1 in PEG1000 grafted cellulose sample before and after 10 times thermal cycling was accepted as the evidence of polyurethane formation. As a result, PEG1000 grafted cellulose phase change composite was found as a potential thermal energy storage material for cooling application in relevant systems. © 2018, This work was supported by Research Fund of the Hakkari University .

Abstract

8 páginas, 4 figuras, 1 tabla.-- Artículo Open Access.-- et al., Using DNA extracted from a finger bone found in Denisova Cave in southern Siberia, we have sequenced the genome of an archaic hominin to about 1.9-fold coverage. This individual is from a group that shares a common origin with Neanderthals. This population was not involved in the putative gene flow from Neanderthals into Eurasians; however, the data suggest that it contributed 4–6% of its genetic material to the genomes of present-day Melanesians. We designate this hominin population ‘Denisovans’ and suggest that it may have been widespread in Asia during the Late Pleistocene epoch. A tooth found in Denisova Cave carries a mitochondrial genome highly similar to that of the finger bone. This tooth shares no derived morphological features with Neanderthals or modern humans, further indicating that Denisovans have an evolutionary history distinct from Neanderthals and modern humans., The Presidential Innovation Fund of the Max Planck Society and the Krekeler Foundation provided financial support.

Abstract

The evolutionary history of alpha-satellite DNA, the major component of primate centromeres, is hardly defined because of the difficulty in its sequence assembly and its rapid evolution when compared with most genomic sequences. By using several approaches, we have cloned, sequenced, and characterized alpha-satellite sequences from two species representing critical nodes in the primate phylogeny: the white-cheeked gibbon, a lesser ape, and marmoset, a New World monkey. Sequence analyses demonstrate that white-cheeked gibbon and marmoset alpha-satellite sequences are formed by units of approximately 171 and approximately 342 bp, respectively, and they both lack the high-order structure found in humans and great apes. Fluorescent in situ hybridization characterization shows a broad dispersal of alpha-satellite in the white-cheeked gibbon genome including centromeric, telomeric, and chromosomal interstitial localizations. On the other hand, centromeres in marmoset appear organized in highly divergent dimers roughly of 342 bp that show a similarity between monomers much lower than previously reported dimers, thus representing an ancient dimeric structure. All these data shed light on the evolution of the centromeric sequences in Primates. Our results suggest radical differences in the structure, organization, and evolution of alpha-satellite DNA among different primate species, supporting the notion that 1) all the centromeric sequence in Primates evolved by genomic amplification, unequal crossover, and sequence homogenization using a 171 bp monomer as the basic seeding unit and 2) centromeric function is linked to relatively short repeated elements, more than higher-order structure. Moreover, our data indicate that complex higher-order repeat structures are a peculiarity of the hominid lineage, showing the more complex organization in humans.
