Authors: Zhou Xiaoping , Ma Lin , Feng Zongcai 
Published: June 2015

Abstract
Bismuth sulfide nanorods were successfully synthesized via a facile solvothermal route. The product was characterized by XRD, FESEM, HRTEM, UV–vis, and PL techniques. XRD results indicated that the obtained bismuth sulfide comprised high-purity orthorhombic phases. FESEM images showed that the products had a rod-like structure with a diameter of about 40 nm and a length of about 600 nm. The optical measurements showed an Eg of 1.65 eV, which might lead to more extensive applications of the as-prepared bismuth sulfide nanorods.

Background: Post-stroke hemiplegic patients of chronic phase often have troubles with their activities of daily life, because of the decrease in upper-limb joint range of motion and the pain of shoulder. Aim: To use a hair-brushing movement intervention with the assistance of a nurse as therapy for increasing the upper-limb joint range of motion in the acute phase in patients with hemiplegia following their first stroke. Method: This study analysed a control group and an intervention group of 26 patients each. The first measurements were made 1–2 days after stroke onset and again on the sixth day from the first measurements. The intervention comprised hair-brushing movements made by patients with the assistance of a nurse. Six joint movement angles were measured on the affected and unaffected sides. Results: Compared with the control group, the intervention group showed a significantly increased (p=0.002) passive joint range of motion in shoulder abduction and external rotation movements on the affected side. Conclusion: Hair-brushing intervention with assistance from nurses increased the joint range of motion of shoulder abduction and external rotation movements.

Abstract
The Kaiser Permanente Research Program on Genes, Environment, and Health (RPGEH) Genetic Epidemiology Research on Adult Health and Aging (GERA) cohort includes DNA specimens extracted from saliva samples of 110,266 individuals. Because of its relationship to aging, telomere length measurement was considered an important biomarker to develop on these subjects. To assay relative telomere length (TL) on this large cohort over a short time period, we created a novel high throughput robotic system for TL analysis and informatics. Samples were run in triplicate, along with control samples, in a randomized design. As part of quality control, we determined the within-sample variability and employed thresholds for the elimination of outlying measurements. Of 106,902 samples assayed, 105,539 (98.7%) passed all quality control (QC) measures. As expected, TL in general showed a decline with age and a sex difference. While telomeres showed a negative correlation with age up to 75 years, in those older than 75 years, age positively correlated with longer telomeres, indicative of an association of longer telomeres with more years of survival in those older than 75. Furthermore, while females in general had longer telomeres than males, this difference was significant only for those older than age 50. An additional novel finding was that the variance of TL between individuals increased with age. This study establishes reliable assay and analysis methodologies for measurement of TL in large, population-based human studies. The GERA cohort represents the largest currently available such resource, linked to comprehensive electronic health and genotype data for analysis.

Abstract
The Kaiser Permanente (KP) Research Program on Genes, Environment and Health (RPGEH), in collaboration with the University of California—San Francisco, undertook genome-wide genotyping of &gt;100,000 subjects that constitute the Genetic Epidemiology Research on Adult Health and Aging (GERA) cohort. The project, which generated &gt;70 billion genotypes, represents the first large-scale use of the Affymetrix Axiom Genotyping Solution. Because genotyping took place over a short 14-month period, creating a near-real-time analysis pipeline for experimental assay quality control and final optimized analyses was critical. Because of the multi-ethnic nature of the cohort, four different ethnic-specific arrays were employed to enhance genome-wide coverage. All assays were performed on DNA extracted from saliva samples. To improve sample call rates and significantly increase genotype concordance, we partitioned the cohort into disjoint packages of plates with similar assay contexts. Using strict QC criteria, the overall genotyping success rate was 103,067 of 109,837 samples assayed (93.8%), with a range of 92.1–95.4% for the four different arrays. Similarly, the SNP genotyping success rate ranged from 98.1 to 99.4% across the four arrays, the variation depending mostly on how many SNPs were included as single copy vs. double copy on a particular array. The high quality and large scale of genotype data created on this cohort, in conjunction with comprehensive longitudinal data from the KP electronic health records of participants, will enable a broad range of highly powered genome-wide association studies on a diversity of traits and conditions.

Published: June 2015

Background and aims. siRNAs represent an encouraging novel alternative in cancer therapy as a result of targeting the mutated tumour suppressor genes or activated oncogenes. Targeting oncogenic signals, as the mutated p53 gene that gains oncogenic role, we observed inhibition of migration, a downregulation of specific genes involved in apoptosis but also in angiogenesis, connected with a reduction in invasion rate in the case of p53siRNA therapy. Methods. The study was designed to assess the role of p53 by using RNAi (RNA interference) in Hela in vitro cell culture model. Therefore cell migration rate was assessed by using xCELLigence Systems, gene expression for a panel of genes involved in apoptosis and angiogenesis, and validation of gene expression data at protein level.Results. On the selected in vitro model p53 siRNA therapy was correlated with the reduction of cell migration. The downregulation of p53, PTEN, TNFα, NFkB, BCL-2, ICAM-2, VEGF, and FGFb was evidenced as response to p53 inhibition.Conclusion. RNAi may be a valuable technology in order to restore the normal cellular phenotype. The results in the current research may also have an important significance outside the context of cervical cancer, by using specific inhibitors for p53 for increasing the therapeutic response in a wide range of tumoral pathology.

Background and aims. Soy supplements are often recommended in the management of menopause symptoms. The declared content of soy supplements is commonly expressed as total isoflavones per dosage form. Given that soy isoflavones have different estrogenic potencies, pharmacokinetics and metabolism, the aim of this study was to evaluate the total isoflavone content and the aglycone profile of seven soy supplements and one soy seed extract. Label accuracy was assessed, in relation to the precise content and the recommended posology for estimating whether the optimal dose is achieved for alleviating menopause symptoms.Materials and Methods. A high performance liquid chromatography method was developed for evaluating the aglycone content (genistein, daidzein, glycitein). After extraction and acidic hydrolysis, the aglycones were separated on a C18 column, using 0.1% acetic acid and acetonitrile as mobile phases. The flow rate was 1.5mL min-1 and the UV detector wavelength was set at 260nm. A linear relationship was found in the range 5-80µg mL-1. The method was validated using the accuracy profile methodology.Results and Discussions. The total isoflavone content ranged from 6.07 to 41.68mg dosage form-1. Various aglycone profiles were obtained for each supplement which can result in a different estrogenic activity, bioavailability and finally, in a different efficiency in alleviating menopause symptoms. In most clinical trials where soy isoflavones were evaluated, little attention was paid to determining the exact aglycone profile of the employed soy extracts.Conclusions. As clinical outcomes continue to be controversial, this study highlights the need of standardization in genistein, rather than total isoflavones and labeling accuracy for soy supplements.

Background and aim. Bone defect reconstruction in the maxillofacial area comes as a necessity after traumatic, oncological or congenital pathology. Custom made implant manufacturing, such as selective laser melting (SLM), is very helpful when bone reconstruction is needed. In the present study we assessed the osseointegration of custom made implants made of Ti6Al7Nb with two different coatings: SiO2-TiO2 and hydroxyapatite, by comparing the bone mineral density (BMD) measured on micro-CT and the histological mineralized bone surrounding the implants.Methods. Custom made – cylindrical type – implants were produced by selective laser melting, coated with SiO2-TiO2 and hydroxyapatite and implanted in the rabbit femur. The animals (divided into 3 groups) were sacrificed at 1, 3 and 6 months and the implants were removed together with the surrounding bone. Bone mineral density and histological examination of the bone-implant surface was performed for each group. Results. BMD and histological examination of the samples determined the quantity of mineralized bone at the implant site, showing a good percentage of mineralized bone for the coated implants at 1, 3 and 6 months, The measurements for the implants without coating showed a significant lower quantity of mineralized bone at 3 months compared with the implants with coating, and a good quantity of mineralized bone at 6 months, showing a process of demineralization followed by remineralization in the last month. The measurements of BMD showed similar results with the histological examination.Conclusions. The use of micro-CT and the measurement of BMD are a reliable, minimally invasive and a quick method of osseointegration assessment.
Sobre urnas griegas y pompas de jabón: transformaciones de la ecfrasis en La casa de los siete tejados

<p>El artículo lleva a cabo un doble ejercicio de literatura comparada: por un lado, explora el papel del arte visual en la organización narrativa de La casa de los siete tejados, de Nathaniel Hawthorne; por otro, examina la manera en que Hawthorne “recicla” el uso que hace John Keats de una ecfrasis inestable en “Oda sobre una urna griega” (donde el poeta inglés medita sobre la noción problemática de inmortalidad artística, y sobre el estatus del poeta moderno frente a los antiguos) para plantear una reflexión propiamente norteamericana sobre el oficio del artista en su sociedad y sobre su propia relación con el canon europeo y con el público estadounidense.</p><p> </p>
¿No es la misma de siempre esta mujer? Género, raza y poesía cubana de los ochenta en la obra poética de Soleida Ríos
Authors: Alemán Lídice 
Published: June 2015

<p>Este artículo se propone determinar cuán revolucionarias fueron las construcciones poético discursivas de las categorías identitarias de raza y género, según las imágenes poéticas creadas por la escritora afrodescendiente cubana Soleida Ríos (Santiago de Cuba, 1950), en la década de los ochenta. Es decir, cómo la poeta se vio a sí misma como mujer negra, dentro de un contexto cuya retórica de igualdad se contradecía con su praxis diferenciadora. Me interesa la evolución de la mujer negra cubana a casi treinta años de iniciado el proyecto revolucionario del “hombre nuevo”. Analizo el diálogo del discurso poético con el discurso dominante (el político), para distinguir cuán considerable fue la participación de este último en la redefinición de las categorías género y raza, teniendo en cuenta que tales conceptos de identidad no son construcciones exclusivamente culturales, sino también políticas, camufladas estratégicamente detrás de lo cultural, tradicional e histórico. </p>

Published: June 2015

ABSTRACTThe BiFeO3/BaTiO3 (BFO/BTO) multilayers were deposited on Pt/Ti/SiO2/Si substrates using sol-gel spin coating technique. The electric and magnetic studies on BFO/BTO multilayer structures were carried out for different number of layers. Enhancement in multiferroic properties were seen for all the prepared multilayers as compared to individual BTO and BFO thin films. Maximum value of ferroelectric polarization 71.18 µC/cm2 and saturation magnetization 69.85 emu/cm3 was obtained for multilayer structure having five layers. The observed enhancement in the multiferroic properties of the multilayer system is due to the increased interfacial stress and multiferroic coupling between the alternating layers.
Li-Doped ZnO Nanoparticles as Novel Direct Generator of Singlet Oxygen for Potential Photodynamic Therapy Applications
Authors: Martínez Julca Milton A. , Rivera Ivonnemary , Perales-Pérez Oscar , Bailón Sonia , Pérez Melina 
Published: June 2015

ABSTRACTPhotodynamic therapy (PDT) is an alternative to traditional cancer treatments. This approach involves the use of photosensitizer (PS) agents and their interaction with light. As a consequence, cytotoxic reactive oxygen species (ROS) are generated that, in turn will destroy tumors. On the other hand, ZnO is a biocompatible, nontoxic, and biodegradable material with the capability to generate ROS, specifically singlet oxygen (SO), which makes this material a promising candidate for 2-photon PDT. Doping ZnO with Li species is expected to induce defects in the host oxide structure that favors the formation of trap states that should affect the electronic transitions related to the generation of SO. The present work reports the effect of the level of Li-doping on the ZnO structure and its capability to generate SO. Li-doped ZnO nanoparticles were synthesized under size-controlled conditions using a modified version of the polyol method. XRD measurements confirmed the development of well-crystallized ZnO Wurtzite; the average crystallite sizes ranged between 13.3nm and 14.2 nm, with an increase in Li content. The corresponding band gap energy values, estimated from UV-vis measurements, decreased from 3.33 to 3.25 eV. Photoluminescence (PL) measurements of Li-ZnO revealed the presence of emission peaks centered on 363nm, 390nm, and 556 nm; these emission peaks correspond to the exciton emission, transition of shallow donor levels near of the conduction band to valence band such as interstitial Zn, and oxygen vacancies, respectively. The observed increase of the emission intensity of the 390 nm emission peak, relative to the intensity of the main emission peak at 363nm, was attributed to the promote of trap states due to interstitial Zn or Li-incorporation into the host oxide lattice. SO measurements evidenced the enhancing effect of the Li concentration on the capability of the doped ZnO to generate this species. This Li-dependence of SO generation can be attributed to the enhancement of the concentration of trap states in the host ZnO, as suggested by PL measurements. Accordingly, Li-ZnO would become cytotoxic to cancer cells via photo-induced ROS generation enabling this nanomaterial to be considered as a potential direct PS agent for the 2-photon PDT route.
