Published: June 2019

Zika virus (ZIKV) is an emerging mosquito-borne flavivirus which is of major public health concern. ZIKV infection is recognized as the cause of congenital Zika disease and other neurological defects, with no specific prophylactic or therapeutic treatments. As the humoral immune response is an essential component of protective immunity, there is an urgent need for effective vaccines that confer protection against ZIKV infection. In the present study, we evaluate the immunogenicity of chimeric viral clone ZIKBeHMR-2, in which the region encoding the structural proteins of the African strain MR766 backbone was replaced with its counterpart from the epidemic strain BeH819015. Three amino-acid substitutions I152T, T156I, and H158Y were introduced in the glycan loop of the E protein (E-GL) making ZIKBeHMR-2 a non-glycosylated virus. Adult BALB/c mice inoculated intraperitoneally with ZIKBeHMR-2 developed anti-ZIKV antibodies directed against viral proteins E and NS1 and a booster dose increased antibody titers. Immunization with ZIKBeHMR-2 resulted in a rapid production of neutralizing anti-ZIKV antibodies. Antibody-mediated ZIKV neutralization was effective against viral strain MR766, whereas epidemic ZIKV strains were poorly sensitive to neutralization by anti-ZIKBeHMR-2 immune sera. From our data, we propose that the three E-GL residues at positions E-152, E-156, and E-158 greatly influence the accessibility of neutralizing antibody epitopes on ZIKV.

Published: June 2019

The aims of our study were to calculate the most appropriate cut-off value for milk samples in a serum-validated Mycobacterium avium subsp. paratuberculosis (MAP) ELISA and to analyze MAP ELISA responses in milk samples from vaccinated and nonvaccinated dairy goats in the Netherlands. Analyzed herds were representative for location and herd size of dairy goat herds in the Netherlands. A significantly higher proportion of the analyzed 49 herds were organic as compared with the total Dutch dairy goat population. First, the MAP ELISA was optimized using 992 paired serum and milk samples. At a cut-off of 25 S/P%, the relative sensitivity (Se) was 58.4% (n = 992, 95% CI: 48.8%−67.6%) and relative specificity (Sp) was 98.5% (n = 992, 95% CI: 97.5%−99.2%), as compared to serum ELISA results. The percentage of positively tested herds was 78.2% (n = 49, 95% CI: 63.4%−88.1%). The percentage of positive milk samples per herd (n = 22) was on average 4.6% (median, min, and max of 4.7%, 0.0%, and 10.7%, respectively). Average age of ELISA-positive (3.2 years) and -negative goats (3.2 years) was not different. Significantly more vaccinated goats tested positive (6.7%) as compared with nonvaccinated goats (1.1%). This study shows that a high number of vaccinated and nonvaccinated commercial dairy goat herds in the Netherlands have MAP-ELISA-positive goats.
Current Practice and Recommendations for Modelling Global Change Impacts on Water Resource in the Himalayas
Authors: Momblanch Andrea , Holman Ian , Jain Sanjay
Published: June 2019

Global change is expected to have a strong impact in the Himalayan region. The climatic and orographic conditions result in unique modelling challenges and requirements. This paper critically appraises recent hydrological modelling applications in Himalayan river basins, focusing on their utility to analyse the impacts of future climate and socio-economic changes on water resource availability in the region. Results show that the latter are only represented by land use change. Distributed, process-based hydrological models coupled with temperature-index melt models are predominant. The choice of spatial discretisation is critical for model performance due to the strong influence of elevation on meteorological variables and snow/ice accumulation and melt. However, the sparsity and limited reliability of point weather data, and the biases and low resolution of gridded datasets, hinder the representation of the meteorological complexity. These data limitations often limit the selection of models and the quality of the outputs by forcing the exclusion of processes that are significant to the local hydrology. The absence of observations for water stores and fluxes other than river flows prevents multi-variable calibration and increases the risk of equifinality. The uncertainties arising from these limitations are amplified in climate change analyses and, thus, systematic assessment of uncertainty propagation is required. Based on these insights, transferable recommendations are made on directions for future data collection and model applications that may enhance realism within models and advance the ability of global change impact assessments to inform adaptation planning in this globally important region.
RuO2-Doped TiO2 Nanotube Membranes Prepared via a Single-Step/Potential Shock Sequence
Authors: Yoo Hyeonseok , Seong Mijeong , Choi Jinsub
Published: June 2019

Anodic TiO2 nanotubes were simultaneously grown and doped with RuO2 by single-step anodization in a negatively-charged RuO4− precursor. Subsequently, a high positive voltage was imposed on the nanotubes in an F−-based electrolyte (a process referred to as potential shock), which led to the formation of a through-hole RuO2-doped TiO2 nanotube membrane without significant loss of the RuO2 catalyst. XPS results confirmed that the doped Ru metal was converted into RuO2 as the potential shock voltage increased. Further increases in the potential shock voltage led to the formation of RuOx/Ru in the TiO2 nanotubes. All of our results clearly showed that a through-hole catalyst-doped TiO2 nanotube membrane can be produced by a sequence consisting of single-step anodization and the potential shock process.

L'étude fondamentale de l'interface solide-liquide permet de mieux comprendre le mode d'action des paramètres qui régissent le procédé de la flottation. Après avoir étudié les phénomènes électrocinétiques aux interfaces et précisé le rôle important des ions H⁺ et OH⁻ dans l'origine de la charge superficielle des minéraux oxydés, les auteurs exposent l'état actuel des connaissances sur l'adsorption des collecteurs et la modulation de la collection (activation et dépression). Les isothermes expérimentales obtenues montrent que l'adsorption des chlorures d'alkylamine, possédant plus de huit groupements CH₂ dans la chaîne alkyl, se fait avec condensation sur surface hétérogène. Différentes énergies de liaisons dans la couche adsorbée sont évaluées ou discutées.

Published: June 2019

Microorganisms have the ability to degrade phenol. However, in Malaysia, there are lack of study on indigenous microorganisms (fungi) that have the ability to degrade phenol. A total of 141 phenol-degrading fungi isolates were isolated from soil and water samples collected from various industrial areas located in Malaysia. The fungi isolate N12 P6C3 was chosen based on its high efficiency in degrading phenol. The fungi isolate N12 P6C3 isolated from a heavy metal factory, Dungun, Terengganu was able to degrade 700 mg/L of phenol within 6 days and the mycelium growth had increased to 0.25 g. The phylogenetic tree based on the ITS sequence analysis confirmed that the fungal identity was closely related to Penicillium janthinellum strain ATCC 4845. The optimum conditions of this fungus to degrade phenol was attained at temperature of 35°C, ammonium sulphate at 3 g/L, 0.05 g/L of sodium chloride, and pH 6. The ability of P. janthinellum strain N12 P6C3 in the degradation of phenol may provide additional knowledge on locally isolated phenol-degrading fungi which could contribute towards phenol waste management in Malaysia.

Published: June 2019

Background Kidney transplantation is the gold standard of treatment in patients with a terminal renal failure. Nevertheless, the main reason for death of recipients, loss of the renal allograft is cardiovascular disease, and disorder of lipid profile remains one of the most significant risk factors and progressing of cardiovascular pathology.
Aim We estimated dyslipidemia dynamics before and at various terms after kidney transplantation and we tried to reveal interrelation of disorder of lipid metabolism with renal transplant functioning.
Material and Methods The retrospective observational research of the cohort in a uniform group of lipid profile dynamics observation in terms before kidney transplantation and in 6, 12 and 36 months of two hundred liver recipients at the age of 40.18±10.33 years has been conducted. Among those there was 41.5% female patients and 58.5% male patients. The statistical analysis was carried out by means of STATISTICA 10.0 program. The critical significance value while checking statistical hypotheses in this research was accepted equal 0.05. The method of multifactorial logistic regression was applied to search factors associated with a dyslipidemia.
Results Level of the general cholesterol before transplantation was 4.34±1.21 mmol/l, in comparison with an initial indicator of the general cholesterol increase in dynamics in 12 and 36 months was 17.5% (р = 0.02), 22.9% (р = 0.03), respectively. The LDL level in the studied cohort of recipients was around 2.36±1.21 mmol, and in 6 months it increased by 12.3% (р = 0.02), in a year for 5.9% (р = 0.21) and 36 months later differed from initial on 14.8 (р = 0.01). In three years after transplantation period LPVP decreased by 12.3% (р = 0.01). In comparison with initial level before transplantation they increased on 8,9% (р = 0,03) и 16,7% (р =0,01) in 12 and 36 months, respectively. The factors associated with dyslipidemia is the age - 1.21-1.7 (р<0.02), diabetes – 1.1-1.5 (р<0.03), the speed of glomerular filtration (kg/sq.m) - 1.23-1.32 (р<0.02), proteinuria (g/l)-1.55-2.1 (р<0.001), the left ventricle myocardium mass index (kg/sq.m)-1.23-1.55 (р <0.03), hemoglobin (g/l)-1.1-1.23 (р<0.04), systolic arterial blood pressure-1.2-2.1 (р<0.001), diastolic arterial blood pressure – 1.1-2.2 (р<0.002). The negative correlational interrelation between the level of cholesterol and survival of the renal allograft, estimated on the speed of glomerular filtration was revealed (р = 0.003). Level of the general cholesterol was a significant independent predictor for survival and functioning of the renal allotransplantat in 3 years after transplantation.
Conclusion The progressing disorder of a lipid profile in the long-term post-transplantation period was revealed, dyslipidemia is a significant modified predictor of successful kidney transplantation.
Long Non-Coding RNA as the Newest Perspective Biomarkers in Cancer
Authors: Beylerli O. A. , Beylerli A. T. , Gareev I. F.
Published: June 2019

Long non-coding RNAs (lncRNAs) are a large group of non-coding RNAs (ncRNAs) which
are more than 200 nucleotides in length. LncRNAs, as regulation factors, show an important role in complex cellular processes, such as apoptosis, growth, differentiation, proliferation, etc. Recently, the results of many studies have also shown their significant role in carcinogenesis. Endogenous lncRNAs are known to be secreted by tumor cells in human biological fluids in the form of microvesicles, exosomes, or protein complexes, thereby forming circulating lncRNAs that do not degrade under the influence of RNases and are in a stable state. Compared with traditional biomarkers, as proteins circulating lncRNA have several advantages that will allow to consider circulating lncRNA as a new potential biomarker for various diseases. Aberrant expression of lncRNAs was observed in cancer patients. In this context, endogenous lncRNAs can regulate the main characteristics of cancer cells, controlling the expression of oncogenes associated with their suppressive and oncogenic functions. Consequently, circulating lncRNAs can be excellent biomarkers for cancer. Knowledge of the molecular mechanisms by which lncRNAs contribute to the development of cancer will improve our understanding of etiology, and open up horizons for the development of new biomarkers. In this paper, we will analyze current knowledge about the change in the expression profile of circulating lncRNAs in cancer, as well as methods for their detection.

Sepsis is the most common cause of neonatal mortality and is responsible for 30-50% of total neonatal deaths each year in developing countries. The objective of the study was to determine the diagnostic accuracy of Creactive protein (CRP) in neonatal sepsis. Fifty nine consecutive patients with risk factors and clinical features suggestive of CRP sepsis were selected as per operational definition and fulfilling the inclusion and exclusion criteria. Detailed physical examination was carried out. Blood sample for culture and CRP was taken from all the patients. Results of blood culture and CRP were noted down in the performa. Statistical analysis was performed by SPSS software version 16. Among selected patients 31/59 (52.5%) were male whereas 28/59 (47.5%) were female. Mean age of all patients was 15.47+7.26 days and mean weight was 2.94+0.63Kg. Temperature instability was present in 79.7%, Tachypnea in 69.5%, Tachycardia in 66.1%, delayed capillary refill in 64.4% and oliguria in 55.9%. Blood cultures were positive in 64.4% and raised CRP was found in 64.5%. Sensitivity, specificity, positive predictive value and negative predictive of raised CRP was found to be 97.3%, 95.2%, 97.3% and 95.2% respectively. In conclusion this study show that C-reactive protein has high sensitivity and specificity for establishing the diagnosis of neonatal sepsis which is comparable to that of blood culture results.
Four self-made free surface electrospinning devices for high-throughput preparation of quality nanofibers
Authors: Fang Yue , Xu Lan
Published: June 2019

Four different self-made free surface electrospinning (FSE) devices, namely, modified bubble-electorspinning (MBE) device, modified free surface electorspinning (MFSE) device, oblique section free surface electorspinning (OSFSE) device and spherical section free surface electrospinning (SSFSE) device, were presented to obtain high-throughput preparation of high quality nanofibers in this paper. The preparation mechanisms of these four FSE device were studied by simulating the electric field distribution using Maxwell 3D, due to the importance of electric field in the FSE process. And the effects of them on the morphology and yield of nanofibers were investigated by experiments. The experimental data agreed with the simulation results of electric field, and showed these four FSE device all could be used to prepare high quality nanofibers in large quantities. Meanwhile, comparing the spinning effects of these four FSE device, the results illustrated the SSFSE device was the optimal FSE device because of the highest quality and yield of nanofibers, and its yield could reach 20.03 g/h at the applied voltage of 40 kV.
Greatly improved adsorption and degradation by S-doped (001)-TiO2 via the vapour-thermal method

Published: June 2019

In this work, sulfur (S) doped (001)-face exposed TiO2 was synthesized via the vapor-thermal method at 180 °C or 250 °C, with an S/Ti molar ratio R
S/Ti of 0, 0.5, 1, 2, 3, 4, and 5. The S-doped samples at 250 °C exhibited significantly improved photocatalytic performance. The effects of S doping were as follows: (1) The S element exhibits different chemical states in the samples with different R
S/Ti. Specifically, it exists in the form of S2− replacing O2− at R
S/Ti = 1, and S6+ replacing Ti4+ at R
S/Ti ≥ 2. As a result, S doping causes a lattice distortion because the ionic radii of S2− and S6+ differ from that of the O2− and Ti4+. (2) S-doping increases the adsorption coefficient A

e
for methylene blue (MB) from 0.9% to 68.5% due to the synergistic effects of the oxygen vacancies, the SO4
2− adsorbed on the TiO2 surface, and the pore size. (3) S-doping increases the MB degradation rate from 6.9 × 10−2 min−1 to 18.2 × 10−2 min−1 due to an increase in the amount of •OH and •O2− radicals.

Protoplanetary disks orbiting intermediate-mass stars, Herbig Ae/Be stars, that have formed in a metal-poor environment may evolve differently than their Galactic cousins. A study of the planet-formation process in such an environment requires identification and characterization of a sample of candidates. We have observed several stars in the Small Magellanic Cloud, a nearby metal-poor dwarf galaxy, that have optical spectral properties of Herbig Ae/Be stars, including strong Hα emission, blue continuum excess, and spectral types ranging from early G to B. Infrared spectra of these sources from the Spitzer Space Telescope show strong excess emission indicating the presence of silicate dust, molecular and atomic gas, and polycyclic aromatic hydrocarbons. We present an analysis of the likelihood that these candidates are Herbig Ae/Be stars. This identification is the necessary first step to future investigations that will examine the role of metallicity in the evolution of protoplanetary disks.
ALMA Observations of a Massive and Dense Cold Clump: G305.137+0.069

Published: June 2019

We report observations, made with the Atacama Large Millimeter/submillimeter Array, of 3 mm dust continuum emission and molecular line emission in HCO+, CS, and N2H+, toward G305.137+0.069, a massive, dense, and cold clump, in order to characterize its small-scale (∼2000 au) structure. The dust continuum observations reveal the presence of twelve compact structures (cores) with masses ranging from 3.3 to 50.6 M
⊙, radii from 1800 to 5300 au, and densities from 3.1 × 106 to 3.1 × 107 cm−3. The line observations show that the molecular emission arises from a bright central region, with an angular size of ∼12″, and an extended, weaker envelope best seen in the HCO+ line. The N2H+ emission is best correlated with the continuum emission and hence with the cores. For cores with single line profiles, the line widths range from 1.9 to 3.1 km s−1 with an average value of 2.6 km s−1, indicating that they are dominated by nonthermal motions, either due to random turbulence or core-scale motions. The virial parameter of the three most massive cores are smaller than one, suggesting that they are undergoing collapse. We find that in the regime of masses probed by our observations (M > 3 M
⊙) the shape of the core-mass function is notably different from the initial mass function, showing an overpopulation of high-mass cores. We suggest that the formation and mass distribution of the dense cores within G305.137+0.069 can be explained as the result of hierarchical or turbulent fragmentation in a gravitationally collapsing clump.

Published: June 2019

Using the quasar spectra from the Sloan Digital Sky Survey and with variable C iv absorption line systems, we measure the Si iv and N v absorption line systems. We obtain 50 variable Si iv absorption line systems and 39 variable N v absorption line systems. We find that the variations in most of the C iv, Si iv, and N v absorption lines are correlated with the changes in quasar continuum. In addition, a significant portion of the variable absorption lines are the consistent variations of multiple systems with large velocity separations. Therefore, the variations of the C iv, Si iv, and N v absorption lines could be mainly driven by the changes in quasar radiations, which cause changes in ionization states or column densities of absorbing gas. We also find that the variable C iv, Si iv, and N v absorption line systems can be divided into low-ionization systems and high-ionization systems. The former positively responds to the changes in the quasar’s brightness, and the later is the oppositive case.
