La campaña electoral como ritual de acceso al poder
Authors: De la Serna Ramos María 
Published: June 2019

Las campañas electorales son el paso previo al acceso al poder institucional de los políticos. Durante los quince días previos a las votaciones se llevan a cabo multitud de eventos de diferentes características que buscan presentar al candidato imbuido en su papel de futuro gobernante: son actos de puesta en escena de sus valores, formas y habilidades. No se diseñan sólo para transmitir un programa, sino, que por encima de todo, lo que pretenden es poner al “futurible” en un entorno propicio para emitir un mensaje de poder. La complejidad de aunar en una buena producción, un buen escenario y un buen mensaje personalizado en el candidato requiere del trabajo en equipo de muchos especialistas: asesores de imagen, escenógrafos y técnicos de protocolo son fundamentales para poner en pie una ilusión que lleve al votante a depositar un determinado voto en las urnas. La complejidad de estos actos, sean de la naturaleza que sean, conlleva un trabajo previo y de un desarrollo en el que el protocolo juega un papel fundamental. En el momento que hay un líder, hay un protocolo.____________________Election campaigns are the previous step for politicians to access institutional power. The numerous events of different kinds held fifteen days prior to voting seek to present the future ruler´s values, manners and skills. Their design is not only meant to present a program, most of the times briefly reviewed before the voters, but to create an enabling environment for sending out a message of power: he is the leader, he has the power and exercises it.The complexity of these acts, which requires a previous teamwork of different specialists like image consultants, set designers and protocol technicians are the main tool to stir up the excitement leading voters to cast ballots in polling stations. In the development of these events, the protocol plays a key role.We´ll discuss a few examples of different events, their production and development, as well as all agents involved in them, from the very first idea to the launch of the event.

CAM: an alignment-free method to recover phylogenies using codon aversion motifs
Authors: Miller Justin B. , McKinnon Lauren M. , Whiting Michael F. , Ridge Perry G. 
Published: June 2019

Background
Common phylogenomic approaches for recovering phylogenies are often time-consuming and require annotations for orthologous gene relationships that are not always available. In contrast, alignment-free phylogenomic approaches typically use structure and oligomer frequencies to calculate pairwise distances between species. We have developed an approach to quickly calculate distances between species based on codon aversion.

Methods
Utilizing a novel alignment-free character state, we present CAM, an alignment-free approach to recover phylogenies by comparing differences in codon aversion motifs (i.e., the set of unused codons within each gene) across all genes within a species. Synonymous codon usage is non-random and differs between organisms, between genes, and even within a single gene, and many genes do not use all possible codons. We report a comprehensive analysis of codon aversion within 229,742,339 genes from 23,428 species across all kingdoms of life, and we provide an alignment-free framework for its use in a phylogenetic construct. For each species, we first construct a set of codon aversion motifs spanning all genes within that species. We define the pairwise distance between two species, A and B, as one minus the number of shared codon aversion motifs divided by the total codon aversion motifs of the species, A or B, containing the fewest motifs. This approach allows us to calculate pairwise distances even when substantial differences in the number of genes or a high rate of divergence between species exists. Finally, we use neighbor-joining to recover phylogenies.

Results
Using the Open Tree of Life and NCBI Taxonomy Database as expected phylogenies, our approach compares well, recovering phylogenies that largely match expected trees and are comparable to trees recovered using maximum likelihood and other alignment-free approaches. Our technique is much faster than maximum likelihood and similar in accuracy to other alignment-free approaches. Therefore, we propose that codon aversion be considered a phylogenetically conserved character that may be used in future phylogenomic studies.

PTMphinder: an R package for PTM site localization and motif extraction from proteomic datasets
Authors: Wozniak Jacob M. , Gonzalez David J. 
Published: June 2019

Background
Mass-spectrometry-based proteomics is a prominent field of study that allows for the unbiased quantification of thousands of proteins from a particular sample. A key advantage of these techniques is the ability to detect protein post-translational modifications (PTMs) and localize them to specific amino acid residues. These approaches have led to many significant findings in a wide range of biological disciplines, from developmental biology to cancer and infectious diseases. However, there is a current lack of tools available to connect raw PTM site information to biologically meaningful results in a high-throughput manner. Furthermore, many of the available tools require significant programming knowledge to implement.

Results
The R package PTMphinder was designed to enable researchers, particularly those with minimal programming background, to thoroughly analyze PTMs in proteomic data sets. The package contains three functions: parseDB, phindPTMs and extractBackground. Together, these functions allow users to reformat proteome databases for easier analysis, localize PTMs within full proteins, extract motifs surrounding the identified sites and create proteome-specific motif backgrounds for statistical purposes. Beta-testing of this R package has demonstrated its simplicity and ease of integration with existing tools.

Conclusion
PTMphinder empowers researchers to fully analyze and interpret PTMs derived from proteomic data. This package is simple enough for researchers with limited programming experience to understand and implement. The data produced from this package can inform subsequent research by itself and also be used in conjunction with other tools, such as motif-x, for further analysis.

Aims: This study investigates the use of sawdust from 3 hardwood species as low-cost adsorbent for the removal of copper from contaminated water.
Study Design: The experimental design used for this study was 3 x 2 x 4 factorial experiment; the different sawdust species, two baselines (treated and untreated) and four levels of pH and time as factors were combined and used for the study.
Methodology: Test was carried out to investigate the effect of sawdust pre-treatment on their adsorption capacity in the removal of Copper ions from contaminated water at different pH levels; the sawdust samples were sieved through a screen size of 850 μm after which a portion of each species sawdust was subjected to pre-treatment by boiling while the other portions were maintained as control samples (untreated).
Results: The results shows that adsorption capacity for both treated and untreated samples were 69.75±13.78%, 68.60±19.48%, 69.34±23.08%, 74.79±17.79%, 74.52±22.30% and 76.90±18.21% for Alstonia boonei, Erythrophleum suaveolens and Ficus mucuso respectively.
Conclusion: The contact time and pH showed no significant difference between the treated and untreated samples. Sawdusts from the selected wood species are suitable to be used as adsorbent towards the removal of copper from contaminated water.
Socio Demographic Factors Associated with Knowledge of Occupational Hazard and Safety Measures among Workers in Selected Downstream Petroleum Companies in Port Harcourt, Rivers State, Nigeria
Authors: Dickson Idungafa, Emem , Tobin-West Charles, 
Published: June 2019

Background: Safety and health management are some of the vital constituents of oil and gas industry activities, because most of the operational conditions, chemicals and end products associated with oil and gas production are well-known to pose serious safety and health threats to the workers. However, these hazards can be prevented and controlled with good safety practices. This study aims to investigate the knowledge, attitude and practices of workers in the downstream petroleum companies about occupational hazards and safety processes.
Materials and Methods: The study was a descriptive cross-sectional study which involved a quantitative approach to collect data from 379 technical workers engaged in operations in the selected downstream petroleum companies, sampled via multi-stage sampling technique. A semi-structured interviewer-administered questionnaire was used to collect relevant information. Data was analysed via Statistical Package for Social Science (SPSS) version 20 software.
Results: Almost one-third 120 (32.0%) of the respondents were between the ages of 38-43 years old. Majority 343 (91.0%) were males, while most 277 (73.0%) were single. Majority 363 (95.8%) had good Level of knowledge on occupational Hazard, while 359 (94.7%) of the respondents had good Level of knowledge on safety measure on occupational hazard. More than one-third 139 (36.70%) had positive behaviour towards preventive measures for occupational hazard, while 167(44%) had good practice towards Safety measures for occupational hazard. Level of knowledge on occupational hazard was significantly associated age, sex and religion (p<0.05).
Conclusion: Though most of the respondents were knowledgeable about occupational hazard and safety measures, positive behaviour towards safety measure and its practice was low among workers in the downstream petroleum companies. Hence the need for behavioural interventional programmes directed at ensuring positive occupational safety related behaviour among workers generally and those in industrial settings particularly.
Holocene Lacustrine Environment in the Western Eritrea-evidence from Freshwater Shells
Authors: Berhe Wegahta Tesfalidet , Ishiga Hiroaki 
Published: June 2019

This study focused on finding of freshwater molluscs in Holocene sediments outcropping in western Eritrea. Three species of gastropods were found in calcareous sediments at the bank of a tributary river named Shatera River, within the license of Bisha Mines, they are Melanoides tuberculate (O. F. Müller, 1774), Bulinus globosus (Morelet, 1866) and Indoplanorbis exustus (Deshayes, 1833). The 14C dating on the shells of I. exustus and B. globosus was also carried out. The age dating result showed (9326-9134 cal yr BP) and (9134-8999 cal yr BP) respectively, of which are in the mid-Holocene epoch (11,000–5000 yr BP). This epoch is best known for it was a time when the northern and eastern part of Africa experienced a warm and humid climate.
Among the freshwater molluscs, the existence of Melanonids tuberculate makes it more significant, for its widespread occurrence in Quaternary deposits throughout Africa and Asia in both fresh and highly evaporated lakes. This is suggestive of the considerable development of the lacustrine environment in the western part of Eritrea, which at present has disappeared.

Published: June 2019

BackgroundChronic rhinosinusitis (CRS) is a significant manifestation of cystic fibrosis (CF) with wide‐ranging symptom and disease severity. The goal of the study was to determine clinical variables that correlate with outcome measures of disease severity.MethodsA prospective, longitudinal, observational study of 33 adults with symptomatic CRS treated in a CF‐focused otolaryngology clinic was performed. Symptom severity, the presence of rhinosinusitis exacerbations, and endoscopic appearance were assessed, and regression analysis was used to determine clinical predictors of disease outcome.ResultsThirty‐three adults with CF‐CRS were included in the study and followed for a mean of 15 months. Rhinosinusitis exacerbations occurred in 61% of participants during the study, and female sex increased the odds of presenting with an exacerbation visit. Sinus disease exacerbations were associated with an odds ratio of 2.07 for presenting with a pulmonary exacerbation at the next visit. CF‐related diabetes was found to be associated with worse symptoms and endoscopic appearance. Infection with Staphylococcus aureus predicted worsening of symptoms, whereas infections with Pseudomonas aeruginosa improved over time. Allergic rhinitis was associated with worse endoscopic appearance, and nasal steroid use was associated with improved endoscopic appearance.ConclusionSex, CF‐related diabetes, sinonasal infection status, allergic rhinitis, and nasal steroid use may all modulate severity of CF‐CRS in adults. Sinusitis exacerbation may be a precursor to pulmonary exacerbation.

BackgroundChronic rhinosinusitis (CRS) is a common disease, often refractory to conventional antimicrobial treatment. In this study we investigate the antimicrobial and anti‐inflammatory effects of adding kappa‐carrageenan to a commercially available sinus rinse.MethodsKappa‐carrageenan was added to Flo CRS and Flo Sinus Care sinus rinses and applied directly to air‐liquid interface cultured primary human nasal epithelial cells (HNECs) from 10 CRS patients. Inflammatory markers were measured using enzyme‐linked immunosorbent assay. Kappa‐carrageenan‒supplemented sinus rinses were applied to human bronchial epithelial cells (HBEs) in the presence of different Staphylococcus aureus strains to observe the effect on intracellular infection rates.ResultsFlo Sinus Care with kappa‐carrageenan rinse solutions resulted in a marked reduction of interleukin‐6 (IL‐6) production by HNECs from CRS patients (p = 0.007). Both Flo CRS and Flo Sinus Care rinses significantly reduced the S aureus intracellular infection of HBEs (p < 0.0001). The addition of kappa‐carrageenan to both Flo CRS and Flo Sinus Care rinses further reduced the intracellular infection rate by an average of 2%.ConclusionsThe commonly used sinus irrigation product Flo Sinus Care with added kappa‐carrageenan reduces IL‐6 production by HNECs in vitro. Flo CRS and Flo Sinus Care rinses significantly reduced S aureus intracellular infection rates of HBE cells. Our findings may have clinical relevance for CRS patient management.
Graphite Anode for a Potassium‐Ion Battery with Unprecedented Performance
Authors: Fan Ling , Ma Ruifang , Zhang Qingfeng , Jia Xinxin , Lu Bingan 
Published: June 2019

AbstractGraphite as an anode for the potassium ion battery (PIBs) has the merits of low cost and potentially high energy density, while suffering from limited cycle time and inferior stability. Herein we, using a concentrated electrolyte, demonstrate that formation of a robust inorganic‐rich passivation layer on the graphite anode could resolve these problems. Consequently, the PIBs with graphite anode could operate for over 2000 cycles (running time of over 17 months) with negligible capacity decay, and had a high area capacity over 7.36 mAh cm−2 with a high mass loading of 28.56 mg cm−2. These unprecedented performances of graphite are comparable to that of traditional lithium‐ion batteries, and may promote the rapidly development of high performance PIBs.
Intrinsic Time‐Tunable Emissions in Core–Shell Upconverting Nanoparticle Systems
Authors: Tessitore Gabriella , Maurizio Steven L. , Sabri Tarek , Capobianco John A. 
Published: June 2019

AbstractColor‐tunable luminescence has been extensively investigated in upconverting nanoparticles for diverse applications, each exploiting emissions in different spectral regions. Manipulation of the emission wavelength is accomplished by varying the composition of the luminescent material or the characteristics of the excitation source. Herein, we propose core–shell β‐NaGdF4: Tm3+, Yb3+/β‐NaGdF4: Tb3+ nanoparticles as intrinsic time‐tunable luminescent materials. The time dependency of the emission wavelength only depends on the different decay time of the two emitters, without additional variation of the dopant concentration or pumping source. The time‐tunable emission was recorded with a commercially available camera. The dynamics of the emissions is thoroughly investigated, and we established that the energy transfer from the 1D2 excited state of Tm3+ ions to the higher energy excited states of Tb3+ ions to be the principal mechanism to the population of the 5D4 level for the Tb3+ ions.
Enhanced mechanical and flame‐resistant properties of polypropylene nanocomposites with reduced graphene oxide‐functionalized ammonium polyphosphate and pentaerythritol
Authors: Chen Xiaosui , Ma Yihan , Cheng Yinjia , Zhang Aiqing , Liu Wei 
Published: June 2019

ABSTRACTA novel functionalized graphene oxide grafted by ammonium polyphosphate (GO‐APP) was synthesized through acylating chlorination method to improve the flame retardancy and mechanical properties of polypropylene (PP) nanocomposites in combination with pentaerythritol (PER). During the mixing process, GO‐APP nanosheets were thermally reduced and PP/rGO‐APP/PER composites were finally obtained. In comparison, PP/rGO‐APP/PER composites exhibit better mechanical, thermal, and flame‐retardant performances than those of PP/APP/PER composites when containing the same loading of total additives. PP/APP/PER 30 wt % composite only passes V‐1 rating in vertical burning tests (UL‐94), whereas PP/rGO‐APP/PER 25 wt % composite ranks V‐0 rating. Furthermore, PP/rGO‐APP/PER 30 wt % composite reaches the highest limiting oxygen index (LOI) value of 31.2%, and its impact strength is almost three times higher than pure PP. The improvement in the fire safety is mainly due to the enhanced char yield, and the “tortuous path” effect caused by intercalate‐exfoliated structures formed in PP/rGO‐APP/PER composites. © 2019 Wiley Periodicals, Inc.

Published: June 2019

AbstractPast sequencing campaigns overlooked small proteins as they seemed to be irrelevant due to their small size. However, their occurrence is widespread, and there is growing evidence that these small proteins are in fact functionally very important in organisms found in all kingdoms of life. Within a global proteome analysis for small proteins of the archaeal model organism Haloferax volcanii, the HVO_2922 protein has been identified. It is differentially expressed in response to changes in iron and salt concentrations, thus suggesting that its expression is stress‐regulated. The protein is conserved among Haloarchaea and contains an uncharacterized domain of unknown function (DUF1508, UPF0339 family protein). We elucidated the NMR solution structure, which shows that the isolated protein forms a symmetrical dimer. The dimerization is found to be concentration‐dependent and essential for protein stability and most likely for its functionality, as mutagenesis at the dimer interface leads to a decrease in stability and protein aggregation.
Structural Mechanism of Barriers to Interspecies Seeding Transmissibility of Full‐Length Prion Protein Amyloid

Published: June 2019

AbstractA puzzling feature of prion diseases is the cross‐species barriers. The detailed molecular mechanisms underlying these interspecies barriers remain poorly understood because of a lack of high‐resolution structural information on the scrapie isoform of the prion protein (PrPSc). In this study we identified the critical role of the residues 165/167 in the barrier to seeding mouse PrP (mPrP) fibril seeds to human cellular prion protein (PrPC). Solid‐state NMR revealed a C‐terminal β‐sheet core spanning residues 165–230 and the packing arrangement of mPrP fibrils. Residues 165/167 are located on one end of the fibril core. Molecular dynamics simulations demonstrated that the stabilities of the seeding‐induced β‐strand structures are significantly impacted by hydrogen bonds involving the side chain of residue 167 and steric resistance involving residue 165. These findings suggest that the α2–β2 loop containing residues 165/167 could be the initial site of seed–template conformational conversion.
