Authors: Zhao Han , Wang Wanpeng , Hu Zhengping , Chen Baihua
Published: July 2019

Background

To investigate the long-term outcomes and complications of scleral-fixated intraocular lens (SFIOL) implantation without conjunctival peritomies and sclerotomy in patients with a history of ocular trauma with inadequate capsular support during primary pars plana vitrectomy or silicone oil removal.

Methods

Records of ocular trauma patients who underwent implantation of SFIOL without conjunctival peritomies and sclerotomy during primary pars plana vitrectomy or silicone oil removal.

Results

Sixty-nine eyes of 69 patients were included in this study. The median follow-up period was 34 months (range, 6-99 months). The average patient age at the time of surgery was 44 years old (range, 4-80 years). At the end of follow-up, the preoperative mean of best corrected visual acuity (BCVA) was 0.79 ± 0.86 log of the minimum angle of resolution (logMAR), which improved 0.20 ± 0.26 logMAR postoperatively (P = 0.01). BCVA improved or remained unchanged in 64 eyes (92.8%), VA decreased two lines in five eyes (7.2%). Early postoperative complications included transient corneal edema in seven eyes (10.1%), minor vitreous hemorrhage in four eyes (5.8%), transient elevated intraocular pressure (IOP) in one eye (1.4%), and hypotony in three eyes (4.3%). Late postoperative complications included persistent elevated IOP in five eyes (7.2%), epiretinal membrane formation in three eyes (4.3%), and cystoid macular edema noted in one eye (1.4%).

Conclusions

Use of a scleral-fixated intraocular lens implantation without conjunctival peritomies and sclerotomy in ocular trauma patients during either primary pars plana vitrectomy or second silicone oil removal is a valuable approach for the management of traumatic aphakia in the absence of capsular support.
An insight into the sialome, mialome and virome of the horn fly, Haematobia irritans
Authors: Ribeiro Jose M. , Debat Humberto Julio , Boiani M. , Ures X. , Rocha S , Breijo Martin
Published: July 2019

Background

The horn fly (Haematobia irritans) is an obligate blood feeder that causes considerable economic losses in livestock industries worldwide. The control of this cattle pest is mainly based on insecticides; unfortunately in many regions, horn flies have developed resistance. Vaccines or biological control have been proposed as alternative control methods, but the available information about the biology or physiology of this parasite is rather scarce.

Results

We present a comprehensive description of the salivary and midgut transcriptomes of the horn fly (Haematobia irritans), using deep sequencing achieved by the Illumina protocol, as well as exploring the virome of this fly. Comparison of the two transcriptomes allow for identification of uniquely salivary or uniquely midgut transcripts, as identified by statistically differential transcript expression at a level of 16 x or more. In addition, we provide genomic highlights and phylogenetic insights of Haematobia irritans Nora virus and present evidence of a novel densovirus, both associated to midgut libraries of H. irritans.

Conclusions

We provide a catalog of protein sequences associated with the salivary glands and midgut of the horn fly that will be useful for vaccine design. Additionally, we discover two midgut-associated viruses that infect these flies in nature. Future studies should address the prevalence, biological effects and life cycles of these viruses, which could eventually lead to translational work oriented to the control of this economically important cattle pest.

Authors: Han Tianyu , Li Mimi , Li Jiawei , Lv Han , Ren Bingru , Chen Jian , Li Weilin
Published: July 2019

Background

Some Gynura species were reported to be natural anti-diabetic plants. The chloroplast genomes of four Gynura species were sequenced for hybridizations to improve agronomic traits. There are only 4 genera of tribe Senecioneae have published chloroplast genome in Genbank up to now. The internal relationships of the genus Gynura and the relationship of the genus Gynura with other genera in tribe Senecioneae need further researches.

Results

The chloroplast genome of 4 Gynura species were sequenced, assembled and annotated. Comparing with other 12 Senecioneae species, the chloroplast genome features were detailedly analyzed. Subsequently, the differences of the microsatellites and repeats type in the tribe were found. By comparison, the IR expansion and contraction is conserved in the genera Gynura, Dendrosenecio and Ligularia. The region from 25,000 to 50,000 bp is relatively not conservative but the 7 ndh genes in this region are under purifying selection with small change in amino acids. The phylogenetic tree shows two major clades, same as the sequence divergence in region 25,000 to 50,000 bp. Based on the oldest Artemisia pollen fossil, the divergence time were estimated.

Conclusions

Sequencing of chloroplast genome of the 4 Gynura species help us to develop abundant genetic resources. The phylogenetic relationships and divergence time among 4 Gynura and 16 Senecioneae species were sorted out by comparing the chloroplast genomes. The phylogenetic relationship of the genera Gynura and Ligularia is different with former work and further morphology and genome-wide analysis are needed to clarify the genera relationship.

Published: July 2019

Globalisation has opened the door for global investors to avoid the saturation of investment opportunities in the domestic market. Latest technological advancement, accessibility to financial and global information, liberalisation and globalisation put the global market into a new investment framework. The present paper aims to examine the level of cointegration between three big Asian economic powers India, China and Japan. Twenty-years data has been analyzed by applying Johansen Cointegration, Vector Error Correction Model, and other econometric statistical tests in E-Views. The findings suggest a long-run relationship between India (BSE) and Japan Stock indices (Nikkie), but no such integration find of these two stock indices with China Stock Exchange (Shanghai).

Published: July 2019

The primary objective was appraisal of groundwater quality during pre- and post-monsoon seasons for irrigation purposes. Good quality groundwater is required for high crop yields in arid regions. A total of 45 samples were collected from wells and analyzed in the laboratory for this research work. Different water quality parameters were determined from these samples, namely electrical conductivity (EC), sodium adsorption ratio (SAR), residual sodium carbonate (RSC), sodium percent (Na%), and permeability index (PI) during the pre- and post-monsoon season. The water types were identified through a Piper-trilinear diagram. Fifty per cent of the water samples of the total basin area fall under the saline category. The local farmers heavily rely on groundwater for the irrigation of crops. Excess use of groundwater for irrigation raises soil salinity. Some parts of the study area are facing serious problems such as loss of crop yields, and low availability of good quality groundwater even for drinking purposes. The results highlight that the study area has a high salinity content (C3) and low sodium (S1). The maps for different water quality parameters were generated using inverse distance weighted (IDW) interpolation method in ArcGIS 10.3 software.
The Roles of Bursal Nonapeptide (BP9) on AIV Vaccine Immune Response in Chick Immunization and on Avian Immature B Cell
Authors: Zheng Yang , Zong Man M. , Chen Bo Y. , Zhou Xiao H. , Liu Zi N. , Zhou Guang F. , Chen Pu Y. , Feng Xiu L.
Published: July 2019

Background:

Bursa of Fabricius plays the vital functions on B cell development and
antibody production in poultry. The bursal-derived peptide plays the essential roles on avian
immature B cell development.

Objectives:

Here we explored the functions of the recently reported bursal nonapeptide (BP9) on
the antibody production and the molecular basis of BP9 on avian immature B cell.

Methods:

Chicken were twice immunized with Avian Influenza Virus (AIV) inactivated vaccine
plus with BP9 at three dosages, respectively. On two weeks after the second immunization, sera
samples were collected from all experimental groups to measure AIV-specific Agglutination
Inhibition (HI) antibody titers. Also, on 7th day after the second immunization, spleen lymphocytes
were isolated from the immunized chicken to detect the lymphocyte viabilities. DT40 cells were
treated with BP9 from 0.02 to 2 μg/mL for 4 and 20h to detect sIgM mRNA levels, and total RNAs
from BP9-treated DT40 cells were collected to investigate the gene expression profiles of DT40
cells, and to analyze the enriched pathways and functional biological processes. Finally, nine gene
expressions were validated with quantitative PCR (qPCR).

Results:

Our investigation proved the strong regulatory roles of BP9 on AIV-specific HI antibody
titers and lymphocyte viabilities. BP9 promoted sIgM mRNA levels in DT40 cells, and upregulated
598 gene expressions and downregulated 395 gene expressions in DT40 cells with 0.2μg/mL BP9
treatment. Moreover, our findings verified the significantly enriched six pathways and various the
biological functional processes of BP9 on avian immature B cell. Also, we found eight signaling
pathways in the enriched biological processes of BP9-treated DT40 cells, and the expressions of
nine selected genes with qPCR were identical to that of microarray data.

Conclusion:

BP9 promoted the antibody production in the 21-old-day chicken immunization, and
stimulated the sIgM expression in DT40 cells. Furthermore, we analyzed the gene expression
profile and immune-related biological processes of DT40 cells treated with BP9, which provided
some new insights into the mechanism on immature B cell development, and provided important
references for adjuvant development on vaccine improvement and clinical application.

Authors: Kraaij Marina D. , van Dijk Albert , Scheenstra Maaike R. , van Harten Roel M. , Haagsman Henk P. , Veldhuizen Edwin J.A.
Published: July 2019

Background:

Cathelicidins are a family of Host Defense Peptides (HDPs), that play an
important role in the innate immune response. They exert both broad-spectrum antimicrobial
activity against pathogens, and strong immunomodulatory functions that affect the response of
innate and adaptive immune cells.

Objective:

The aim of this study was to investigate immunomodulation by the chicken cathelicidin
CATH-2 and compare its activities to those of the human cathelicidin LL-37.

Method:

Chicken macrophages and chicken monocytes were incubated with cathelicidins.
Activation of immune cells was determined by measuring surface markers Mannose Receptor Ctype
1 (MRC1) and MHC-II. Cytokine production was measured by qPCR and nitric oxide
production was determined using the Griess assay. Finally, the effect of cathelicidins on
phagocytosis was measured using carboxylate-modified polystyrene latex beads.

Results:

CATH-2 and its all-D enantiomer D-CATH-2 increased MRC1 and MHC-II expression,
markers for antigen presentation, on primary chicken monocytes, whereas LL-37 did not. D-CATH-
2 also increased the MRC1 and MHC-II expression if a chicken macrophage cell line (HD11 cells)
was used. In addition, LPS-induced NO production by HD11 cells was inhibited by CATH-2 and
D-CATH-2.

Conclusion:

These results are a clear indication that CATH-2 (and D-CATH-2) affect the
activation state of monocytes and macrophages, which leads to optimization of the innate immune
response and enhancement of the adaptive immune response.

Can balance-of-payments constrained economies pursue inflation targeting? A look at the case of Chile
Authors: Pérez Caldentey Esteban
Published: July 2019

The economic performance of small economies is dtermined to a greater extent by the existing financial architecture. The current financial system is anchored on the United States dollar and countries that do not issue the reserve currency, especially small open economies, must be able to acquire, and indeed accumulate, the currency they cannot issue ti pay for their imports and to carry other type of real and financial transactions. As a result, contries domestic policies, and in particular those of small open economies are to a greater extent shaped and constrained by their external conditions and performance. In this sense they are said to be balance-of-payments constrained.
LA NATURALEZA DE UNA ECONOMÍA
Authors: Leijonhufvud Axel
Published: July 2019

La crisis financiera y la recesión que se derivó de ella han propiciado una reexaminación del estado de la teoría macroeconómica. La imagen de una economía capitalista comoun sistema de equilibrio general estable un tanto obstaculizado en su funcionamiento por “fricciones” es, creo, una guía inadecuada para las realidades con las que tenemos que enfrentarnos. Este artículo enfatiza que tenemos que pensar a la economía como un “sistema abierto” en el sentido ontológico de Tony Lawson. Esto requerirá que adaptemos nuestros métodos a la naturaleza de una economía –para cambiar la manera en la que hacemos economía. Se argumenta también que la economía no es globalmente estable sino que entraña inestabilidades. La crisis debió de habernos curado de la “presunción de conocimiento” (Caballero, 2010) –de la ilusión de que entendíamos muy bien los problemas de la inestabilidad macroeconómica y de que los habíamos resuelto todos para la satisfacción general. Una vez curados de esta presunción –lo que equivale a decir, una vez conscientes de nuestra ignorancia– podemos ver que la macroeconomía plantea muchas preguntas importantes para las cuales mi generación no proporcionó buenas respuestas.
THE SOURCES AND EVOLUTION OF INEQUALITY IN MEXICAN EJIDOS
Authors: Alix-Garcia Jennifer
Published: July 2019

This paper examines the sources of inequality in the Mexican common property communities (ejidos), both in the past and in the present. It uses as a proxy of historical inequality the distribution of land at the time of the Agrarian Reform, and as a proxy for current distribution the number of cattle held by individuals. Possible hypotheses of factors affecting the distribution are pre-colonial population densities, differing eligibility rules through the course of the Agrarian Reform, and geography. Decomposition of the inequality measures shows that land inequality is much higher between than within ejidos, with the opposite being true for cattle inequality. Higher pre-colonial population densities are shown to decrease the average amount of privateland and of cattle held by ejido members, and to decrease within ejido-land inequality while they increase within-ejido cattle inequality. Ejidos formed during the early periodof the reform have significantly larger land endowments, and much greater inequality within them currently. Finally, geography is an important determinant of both land and cattle distribution within and between ejidos, even while controlling for other factors.This suggests roles for both geography and institutions in the determination of the distribution of assets in rural Mexico.
GESTIÓN AMBIENTALMENTE RESPONSABLE Y VALOR DE MERCADO DE LAS ACCIONES EN SITUACIONES DE CRISIS FINANCIERA
Authors: Déniz-Mayor José Juan , Verona-Martel María Concepción
Published: July 2019

En el presente trabajo se estudia la valoración de la gestión ambientalmente responsable de las empresas por el mercado de acciones español. Un análisis del efecto en el precio de las acciones de las noticias publicadas en la prensa escrita durante el periodo 2000-2010, alusivas a actuaciones positivas sobre el medio ambiente por parte de empresas cotizadas, ofrece como conclusión significativa que existen evidencias de que los inversores reaccionan de forma diferente ante noticias relacionadas con gastos e inversiones dependiendo de si la situación económica del país se encuentra en fase de crecimiento o bien de crisis, siendo positiva en el primer caso y negativa en el segundo, no observándose una evidencia indisputable para el resto de noticias ambientalmente positivas. Estos hallazgos abonan la teoría de que los inversores consideran relevante las políticas corporativas en materia de medio ambiente y que su reacción está condicionada por el clima económico imperante.
INVERSIÓN EN INVESTIGACIÓN Y CRECIMIENTO ECONÓMICO: UN ANÁLISIS EMPÍRICO DESDE LA PERSPECTIVA DE LOS MODELOS DE I+D
Authors: Marroquín Arreola Juan , Ríos Bolivar Humberto
Published: July 2019

Este trabajo analiza, para el caso de México, algunos planteamientos de los modelos de crecimiento económico basados en Investigación y Desarrollo (I+D), donde se afirma que la innovación es creada en el sector de I+D y que ello permite un crecimiento económico sostenido, siempre que haya rendimientos constantes a la innovación en términos de I+D. Para el análisis se utilizan las técnicas de datos de panel y se emplean datos de patentes y de I+D para 32 estados de la república mexicana. Los resultados coinciden en alguna medida con el planteamiento de la teoría del crecimiento endógeno, ya que confirma una relación significativa entre el stock de I+D y la innovación, y entre la innovación y el producto interno bruto (PIB) per cápita.
¿MODELO DE CRECIMIENTO EXPORTADOR O MODELO DE ESTANCAMIENTO EXPORTADOR? EL CASO DE MÉXICO, 1961-2010
Authors: Vázquez Muñoz Juan Alberto , Avendaño Vargas Blanca Lilia
Published: July 2019

Presentamos una pequeña modificación de la Ley de Thirlwall a través de la consideración de los requerimientos de importación del sector exportador, en específico, introducimos la idea de la elasticidad exportaciones de la demanda de importaciones. Dadas la tasa de crecimiento de las exportaciones y la elasticidad ingreso de la demanda de importaciones, una más alta elasticidad exportaciones de la demanda de importaciones implica una más baja tasa de crecimiento consistente con el equilibrio de la balanza de pagos. Este argumento es corroborado de forma empírica para el caso de la economía mexicana, la cual exhibió casi las mismas tasas de crecimiento de las exportaciones y la elasticidad ingreso de la demanda de importaciones durante el periodo del Tratado de Libre Comercio de América del Norte (TLCAN), en comparación con el periodo de 1961 a 1981. Sin embargo, exhibió una fuerte reducción de su tasa de crecimiento acorde con el equilibrio externo, debido a un sustancial incremento de su elasticidad exportaciones de la demanda de importaciones.

Published: July 2019

In this study, Al0.3Ga0.7N/GaN high electron mobility transistor (HEMT) structure is investigated grown over c- oriented sapphire substrate by using Metal Organic Chemical Vapor Deposition (MOCVD) method. Optical, morphological and electrical characteristics of this structure are determined by X-ray diffraction (XRD), Photoluminecanse (PL), Ultraviolet (UV-Vis.), Atomic Force Microscopy (AFM) and Hall- Resistivity measurements. By using XRD method, 2θ, Full Width at Half Maximun (FWHM), lattice parameters, crystallite size, strain, stress and dislocation values are calculated on symmetric and asymmetric planes. Direct band gap of GaN is determined by PL measurements as 3.24 eV. It is seen that conduction of AlGaN layer starts at 360 nm in UV-Vis. In Hall-Resistivity measurements, it is noticed that carrier density of HEMT structure is not effected by temperature and mobility value is high. Carrier density and mobility values are determined as 5.82x1015 1/cm3 and 1198 cm2/Vs at room temperature respectively. At the lowest temperature point (25 K) they are calculated as 5.19x1015 1/cm3 and 6579 cm2/Vs, respectively.

In this study, we investigated the toxic effects of the captan fungicide
by using morphological, physiological and cytological parameters in bell pepper
(Capsicum annuum L. var. grossum L.
cv. Kandil) root tissue. The seeds of bell pepper were germinated in Petri dishes
including different concentrations (0, 25μM, 50μM, 100μM, 150μM) of captan
fungicide for 7 days. The germination rates and root lengths were significantly
reduced in captan-treated seeds. All concentrations caused a significant
decrease in mitotic index and increase in different types of chromosomal
abnormalities such as c-mitosis and chromosome stickness in meristematic cells
of bell pepper root. Captan treatment also induced oxidative stress by leading
to membrane damage with an increase in root electrolyte leakage in 7 days-old
bell pepper root. Catalase, glutathione reductase and total peroxidase
activities increased under different concentrations as a response to oxidative
stress. Our results showed that captan fungicide had negative effects on germination
and growth in bell pepper seed.

The development of the digital economy can aggravate the existing problems of the Russian labour market (the high level of informal employment, low labour mobility, growth of precarious employment etc.), can cause a growth of technological unemployment. Automation and digitalization would change most task sets within particular occupations, would radically change distribution of workers by occupations. By 2022, about 53% of labour forces can be re-trained. The Russian employment services have to become an effective structure of mass retraining. The analysis of in-depth expert’s interviews reveals an organizations problem of retraining programs (the focus on the functional tasks of the employment services, the low efficiency of programs, the insufficient financing, the lack relations of the employment services with employers, etc). The authors focused on a problem of interaction between the federal level (Federal service of labor and employment) and regional departments and the employment services. Now, it is necessary to strengthen the role of the federal bodies for the formation of a proactive employment policy. This measure will help us to move from the existing fragmentation in employment management, to transfer the experience and knowledge of the Federal service to all regional structures. Active work of employment services will help to reduce social inequality, will not allow excluding a most of Russian workers from high-paid, high-tech branches of the digital economy.

The effect of dietary supplementation with a biotechnological extract of Ajuga reptans on growth performance, oxidative status and immune parameters was evaluated in post weaning piglets. At weaning, 120 piglets with an average live weight of 8.1±1.3 kg, were assigned to one of three experimental groups. The first group was fed a control diet (C). The second and third groups were fed the same diet supplemented with 5 mg (T1) and 10 mg (T2) of teupolioside/kg feed from a biotechnological plant extract. Growth performances were recorded and blood samples were collected at the beginning, at 14 days, and at the end of the trial (56 days). Serum biochemical parameters, oxidative status and immunoglobulin titres were determined. Average daily gain tended to be higher (P=0.057) and live weight was higher in piglets (P<0.05) fed with different amounts of plant extract (T1 and T2) than the controls. The production of reactive oxygen metabolites (ROMs) was higher (P<0.05) in the control group than in the groups receiving teupolioside (T1 and T2). Concentration of serum immunoglobulin of class G improved (P<0.001) in piglets fed the T1 and T2 diets than the controls. Overall, the results suggested that the biotechnological extract of Ajuga reptans containing teupolioside has an antioxidant and immunomodulant effect.

The aim of the research was to determine the affectivity of 4 different eubiotic preparations on the growth performance of pigs, microbial status, the integrity of intestinal mucosa, and some blood parameters. The experiment was conducted for 28 days on 48 male piglets allocated to six dietary treatments. Group 1 was offered a diet without eubiotic; 2 – a diet with acids mixture; 3 – phytobiotic, medium-chain fatty acids (MCFA) and yeast; 4 – probiotic, MCFA, and yeast; 5 – phytobiotic, probiotic, acids mixture, and sodium butyrate; 6 – phytobiotic, probiotic, MCFA, and sodium butyrate. The average daily weight gains and feed intake were recorded. Blood samples, digesta samples, and ileal tissue samples were collected for studies. There was no significant difference in gain, feed intake, or FCR among the treatments as well as in the ileal and caecal pH value, microbial content, and total SCFA content in caecal digesta. Ammonia content in ileal digesta was significantly higher in comparison with other groups and in caecal digesta was significantly higher in group 6 in comparison with groups 1 and 2. Villi height was significantly higher (P<0.05) in groups 2, 3 and 6 compared to the control. Villi height to crypt depth ratio was significantly higher (P<0.05) in groups 5 and 2, but the most promising effects seem to be from combinations 3 and 4. In comparison with control: in groups 2, 3 and 5 higher ALT, glucose and triglyceride; in groups 3, 4 and 5 higher total protein and cholesterol; in group 4 higher albumin and in group 6 higher BUN, were found. Generally, used eubiotic preparations affected gut morphology and some blood parameters but did not affect microbiota, pig growth or feed utilization.

Published: July 2019

Sweet cherries (Prunus avium L.) contain various phenolic compounds which contribute to total antioxidant activity. The present study was conducted to assess the antioxidant activity of 15 sweet cherry cultivars from Vojvodina province (north Serbia). The free radical scavenging properties of fruits were evaluated employing two different methodologies, including DPPH (2,2-diphenyl-1-picrylhydrazyl) radical scavenging assay and ferric reducing antioxidant power (FRAP) assay. Strong correlations were found between total phenolics, tannins, flavonoids and anthocyanins and DPPH and FRAP assays. In particular, cultivar Peter showed the highest antioxidant capacity and possesses the highest amount of measured phenolic compounds. This investigation shows large variability among sweet cherry cultivars in measured chemical attributes.

Within a project co-funded by the Italian Ministry of Foreign Affairs, the final aim of which is to develop a WSN for smart monitoring of pesticides on agricultural land, the Italian and Serbian researchers have developed a hardware section of an electronic nose for pesticides. Since there are no specialized sensors which can smell the presence or absence of pesticides in the air, the electronic nose has been designed starting from an array of commercial gas sensors developed for other environmental applications. These sensors have a great advantage as they are COTS components. A measurement bench for testing the performance of the system has also been developed. Experimental tests have been conducted and the results have demonstrated the appropriateness of the idea. A test for calibration has been designed, as well, and it will be performed in the near future.
