Papillomaviruses (PVs) are a diverse group of host species-specific DNA viruses, etiologically linked with various benign and malignant neoplasms of cutaneous and mucosal epithelia. Here, we describe the detection and characterization of the first two PVs naturally infecting Japanese macaques (Macaca fuscata), including the determination of their etiological association(s) with the development of original neoplasms. The molecular and phylogenetic analyses were performed on complete genome sequences of Macaca fuscata PV types 1 (MfuPV1) and 2 (MfuPV2), which were completely sequenced in samples of a malignant oral tumor and benign anogenital neoplasm of Japanese macaques, respectively. Subsequently, two type-specific quantitative real-time PCRs were developed to estimate viral loads of MfuPV1 and MfuPV2 and to evaluate their etiological roles. The in silico molecular analyses revealed that both viral genomes encode characteristic PV proteins with conserved functional domains and have a non-coding genomic region with regulatory sequences to regulate and complete the viral life cycle. However, additional experimental evidence is needed to finally confirm the presence and biological functionality of the molecular features of both novel PVs. While MfuPV1, together with PVs identified in other macaques, is classified into the Alphapapillomavirus (Alpha-PV) species 12, MfuPV2 is most likely a representative of the novel viral species within the Alpha-PV genus. Their relatively high viral loads suggest that both PVs are etiologically linked with the development of the original neoplasms.

Pseudomonas syringae pv. actinidiae (Psa) is a phytopathogen that causes canker in kiwifruit. Few conventional control methods are effective against this bacterium. Therefore, alternative approaches, such as phage therapy are warranted. In this study, a lytic bacteriophage (PN09) of Psa was isolated from surface water collected from a river in Hangzhou, China in 2019. Morphologically, PN09 was classified into the Myoviridae family, and could lyse all 29 Psa biovar 3 strains. The optimal temperature and pH ranges for PN09 activity were determined as 25 to 35 ∘C and 6.0 to 9.0, respectively. The complete genome of PN09 was found to be composed of a linear 99,229 bp double-stranded DNA genome with a GC content of 48.16%. The PN09 endolysin (LysPN09) was expressed in vitro and characterized. LysPN09 was predicted to belong to the Muraidase superfamily domain and showed lytic activity against the outer-membrane-permeabilized Psa strains. The lytic activity of LysPN09 was optimal over temperature and pH ranges of 25 to 40 ∘C and 6.0 to 8.0, respectively. When recombinant endolysin LysPN09 was combined with EDTA, Psa strains were effectively damaged. All these characteristics demonstrate that the phage PN09 and its endolysin, LysPN09, are potential candidates for biocontrol of Psa in the kiwifruit industry.

Published: April 2021

A new variant of SARS-CoV-2 B.1.351 lineage (first found in South Africa) has been raising global concern due to its harboring of multiple mutations in the spike that potentially increase transmissibility and yield resistance to neutralizing antibodies. We here tested infectivity and neutralization efficiency of SARS-CoV-2 spike pseudoviruses bearing particular mutations of the receptor-binding domain (RBD) derived either from the Wuhan strains (referred to as D614G or with other sites) or the B.1.351 lineage (referred to as N501Y, K417N, and E484K). The three different pseudoviruses B.1.351 lineage related significantly increased infectivity compared with other mutants that indicated Wuhan strains. Interestingly, K417N and E484K mutations dramatically enhanced cell–cell fusion than N501Y even though their infectivity were similar, suggesting that K417N and E484K mutations harboring SARS-CoV-2 variant might be more transmissible than N501Y mutation containing SARS-CoV-2 variant. We also investigated the efficacy of two different monoclonal antibodies, Casirivimab and Imdevimab that neutralized SARS-CoV-2, against several kinds of pseudoviruses which indicated Wuhan or B.1.351 lineage. Remarkably, Imdevimab effectively neutralized B.1.351 lineage pseudoviruses containing N501Y, K417N, and E484K mutations, while Casirivimab partially affected them. Overall, our results underscore the importance of B.1.351 lineage SARS-CoV-2 in the viral spread and its implication for antibody efficacy.

Published: April 2021

European bat lyssavirus type 1 (EBLV-1) is the causative agent for almost all reported rabies cases found in European bats. In recent years, increasing numbers of available EBLV-1 full genomes and their phylogenetic analyses helped to further elucidate the distribution and genetic characteristics of EBLV-1 and its two subtypes, namely EBLV-1a and EBLV-1b. Nonetheless, the absence of full-genome sequences from regions with known detections of EBLV-1 still limit the understanding of the phylogeographic relations between viruses from different European regions. In this study, a set of 21 archived Danish EBLV-1 samples from the years 1985 to 2009 was processed for the acquisition of full-genome sequences using a high-throughput sequencing approach. Subsequent phylogenetic analysis encompassing all available EBLV-1 full genomes from databases revealed the Danish sequences belong to the EBLV-1a subtype and further highlighted the distinct, close phylogenetic relationship of Danish, Dutch and German isolates in this region. In addition, the formation of five putative groups nearly exclusively formed by Danish isolates and the overall increased resolution of the EBLV-1a branch indicate a higher genetic diversity and spatial segregation for this sublineage than was previously known. These results emphasize the importance of phylogenetic analyses of full-genome sequences of lyssaviruses for genetic geography.

Published: April 2021

Chronic hepatitis C infection (HCV) activates a systemic cell-mediated immune response characterized by the production of IFNγ and an innate immune response addressed by the activation of TLR signaling. We aimed to investigate whether HCV eradication by direct acting antivirals (DAA) leads to a recovery in cell-mediated immune response and TLR expression and functionality. Blood samples were obtained in HCV infected patients before DAA treatment and at week +48 after the end of treatment. Results were compared to healthy controls. Cell surface expression of TLR8 was assessed on peripheral blood mononuclear cells (PBMCs) by flow cytometry. Freshly isolated PBMCs were cultured with specific TLR8 agonists and intracellular production of cytokines was determined by flow-cytometry after ex vivo TLR8 activation with ssRNA 40. Production of IFNγ, IL2 and IL17 was assessed by flow cytometry in T cells after polyclonal activation. Included were 50 HCV-infected patients and 15 controls. TLR8 expression in PBMCs was significantly increased before treatment and recovered normal levels at week +48. Production of IL1b, IL6 and TNFα dependent on the activation of TLR8 in PBMCs was also increased in patients before DAA treatment, with a significant reduction at week +48. Combined expression of IFNγ and IL2 in CD4+ T cells in HCV-infected patients was significantly increased compared to controls and recovered normal levels at week +48. DAA-mediated clearance of HCV is associated with a decreased expression and activation of TLR8 in PBMCs until healthy control levels which is accompanied by a reduction in the Th1 response.

Published: April 2021

Modified-live vaccines (MLVs) against porcine reproductive and respiratory syndrome viruses (PRRSVs) are usually administrated to piglets at weaning when swine influenza A virus (swIAV) infections frequently occur. SwIAV infection induces a strong interferon alpha (IFNa) response and IFNa was shown to abrogate PRRSV2 MLV replication and an inherent immune response. In this study, we evaluated the impacts of swIAV infection on the replication of a PRRSV1 MLV (MLV1), post-vaccine immune responses and post-challenge vaccine efficacy at both the systemic and pulmonary levels. Piglets were either swIAV inoculated and MLV1 vaccinated 6 h apart or singly vaccinated or mock inoculated and mock vaccinated. Four weeks after vaccination, the piglets were challenged with a PRRSV1 field strain. The results showed that swIAV infection delayed MLV1 viremia by six days and post-vaccine seroconversion by four days. After the PRRSV1 challenge, the swIAV enhanced the PRRSV1-specific cell-mediated immunity (CMI) but the PRRSV1 field strain viremia was not better controlled. High IFNa levels that were detected early after swIAV infection could have been responsible for both the inhibition of MLV1 replication and CMI enhancement. Thus, whereas swIAV infection had a negative impact on humoral responses post-vaccination, it did not interfere with the protective effectiveness of the PRRSV MLV1 in our experimental conditions.
Hotspots of Legacy Phosphorus in Agricultural Landscapes: Revisiting Water-Extractable Phosphorus Pools in Soils

Published: April 2021

Controlling phosphorus (P) losses from intensive agricultural areas to water bodies is an ongoing challenge. A critical component of mitigating P losses lies in accurately predicting dissolved P loss from soils, which often includes estimating the amount of soluble P extracted with a laboratory-based extraction, i.e., water-extractable P (WEP). A standard extraction method to determine the WEP pool in soils is critical to accurately quantify and assess the risk of P loss from soils to receiving waters. We hypothesized that narrower soil-to-water ratios (1:10 or 1:20) used in current methods underestimate the pool of WEP in high or legacy P soils due to the equilibrium constraints that limit the further release of P from the solid-to-solution phase. To investigate P release and develop a more exhaustive and robust method for measuring WEP, soils from eight legacy P fields (Mehlich 3–P of 502 to 1127 mg kg−1; total P of 692 to 2235 mg kg−1) were used for WEP extractions by varying soil-to-water ratios from 1:10 to 1:100 (weight:volume) and in eight sequential extractions (equivalent to 1:800 soil-to-water ratio). Extracts were analyzed for total (WEPt) and inorganic (WEPi) pools, and organic (WEPo) pool was calculated. As the ratios widened, mean WEPi increased from 23.7 mg kg−1 (at 1:10) to 58.5 mg kg−1 (at 1:100). Further, WEPi became the dominant form, encompassing 92.9% of WEPt at 1:100 in comparison to 79.0% of WEPt at 1:10. Four of the eight selected soils were extracted using a 1:100 ratio in eight sequential extractions to fully exhaust WEP, which removed a cumulative WEPt of 125 to 549 mg kg−1, equivalent to 276–416% increase from the first 1:100 extraction. Although WEP concentrations significantly declined after the first sequential extraction, WEP was not exhausted during the subsequent extractions, indicating a sizeable pool of soluble P in legacy P soils. We conclude that (i) legacy P soils are long-term sources of soluble P in agricultural landscapes and (ii) the use of a 1:100 soil-to-water ratio can improve quantification and risk assessment of WEP loss in legacy P soils.
Theoretical Estimation of Energy Balance Components in Water Networks for Top-Down Approach

Published: April 2021

The energy balance calculation for pressurized water networks is an important step in assessing the energy efficiency of water distribution systems. However, the calculation generally requires mathematical modelling of the water networks to estimate three important energy components: outgoing energy through water loss (El), friction energy loss (Ef) and energy associated with water loss (EWL). Based on a theoretical energy balance analysis of simplified pipe networks, a simple method is proposed to estimate El, Ef and EWL with minimum data requirements: input energy, water loss (WL) and head loss between the source and the minimum energy point (ΔH). By inclusion of the head loss in water networks into the estimation, the percentages of El and EWL are lower and higher, respectively, than using only the percentage of WL. The percentage of Ef can be a function of the percentage of ΔH. By demonstrating our analysis with the simulation results from the mathematical models of 20 real water networks, the proposed method can be used to effectively estimate El, Ef and EWL as a top-down energy balance approach.

Published: April 2021

We propose an image file format that can be read in two ways, where two images are recorded in a single file as a bit sequence, and the forward reading the bit sequence makes one of the two images visible, or the backward reading makes another image visible. Such a way of looking at a binary data in two ways resembles that of an ambigram, which is a piece of calligraphy that can be read in two ways by rotating it or introducing other perspectives. The proposed ambigramic image file format is compared with the graphics interchange format (GIF) experimentally, and the results show the better quality of the ambigramic images than that of GIF images.

Security in Wireless Sensor Networks: Issues and Challenges
Authors: Thangamuthu A P
Published: April 2021

Wireless sensor networks (WSNs) have made it easier for people to live in various fields: medical engineering, agriculture. With computing power and wireless networking, sensing technology makes it lucrative for its potential abundance of use. Since the many uses of such systems have been used, lightweight, inexpensive, disposable and self-contained computers, known as sensor nodes or “motes,” are created. WSNs are commonly used in applications for monitoring, tracking and control. These include centralized management, system heterogeneity, protocol routing, the versatility of node, the privacy of information and restricted computing capacity. WSN covers a wide geographical area; routing protocols, scalability and security should therefore be addressed. In the traditional networking technique, there are major benefits due to the low cost and cooperative design of wireless networks (WNs). The networks with wireless sensors have more advantages over wired networks. Although wireless networks have various advantages, they are vulnerable to security problems. Due to the broader application, safety has become an important issue for wireless sensor networks.

The main objective of this paper is to present the activities carried out and the results obtained during the design of a three-phase bidirectional meter for a photovoltaic system interconnected to the network. The tests for validation and start up of the bidirectional meter used for wireless measurement and monitoring of the main consumption parameters and electric power generation are described: voltage, current, active power (W), apparent power (VA), power factor and power consumption (kWh). This bidirectional meter was born as a proposal to solve the problem related to the measurement of electric power in photovoltaic systems interconnected to the network, since the bidirectional meters currently installed by the power company (CFE, Comisión Federal de Electricidad) have an inconvenience, they can only be distributed and installed by the same company. It is a low cost and easy installation bidirectional meter. The main advantage of this bidirectional meter is the facility offered to the user to read and understand the readings of the measurements made, displayed on a personal computer screen or a mobile application. Furthermore, the history of the power consumption (kWh) show in the meter database helps the user in making decisions regarding cost reduction.

Published: April 2021

The tidal currents constitute a clean and inexhaustible source of energy. The determination of its magnitude in the north of the Gulf of California with a view to its use, represented the central objective of this work. The methodology included an exhaustive search of measurements of tidal currents, the generation of a text file of ordered time-speed data (history of speeds as a tabulation) from the found graphs of speeds, and finally its processing, which consisted of the histories of the current power density and power generated by a standard turbine, as well as the corresponding graphs of frequency and equivalence with respect to a continuous generation plant. The results show that the energy available in the tidal currents of the northern region of the Gulf of California is lower than that of other areas of the world with radical tidal changes; however, it is considered that the installation of several farms instead of one, located in the places where the currents reach higher speeds, together with the use of other renewable sources available in the region, constitute altogether an important option that must be considered.

Demand for electrical energy and rising production costs, coupled with the need to favor renewable energies, mean that alternative solutions must be proposed which, in addition to reducing consumption costs, are sustainable solutions with very low environmental impact. Although a solution has been given with the use of solar cells, these can still be expensive or require additional maintenance in the fixation and support systems when they are in zones of high nitrate concentrations. As a rule these coastal areas have the advantage of receiving wind of different speeds during prolonged periods of time during the day, which can facilitate the placement of electric generators by windmills. In the Faculty of Engineering, a zoned study was carried out on wind speeds and directions over a long period of time, in order to establish the conditions and feasibility of the placement of these generators, considering the topography and typology of the place measured speeds and directions on one of the complex buildings. Thus, a register was obtained that allows calculating the energy production and the convenience of exploiting this clean and sustainable energy solution.

The Gas Diffusion Layer (GDL) provides a transport route for the reactant species from the flow channels to the catalytic layer in a fuel cell. The components design requires that the species present a uniform diffusion towards the electrodes and that the formed products are shifted as faster as possible, to avoid the increase of the ohmic resistance due to the blocking of the active sites, or it constitutes a bottleneck that the performance decrease fast. This work presents a solution proposal for the continuity equation in incomprenssible fluids in a 3D model of a gas diffuser layer with titanium wired mesh characteristics of a fuel cell using "OpenFOAM" open source software. The aim of the study is to show that under different scales or size of the gas diffusion layer there are significant changes in the velocities of propagation of the reactant species towards the active area of the fuel cell.

Published: April 2021

Using giant characeaen algae Nitellopsis obtusa in laboratory exercises is proposed to familiarize students with basic concepts of electrophysiology and provide some simple hands-on practice. The described concept experiments present extracellular registration of action potentials (APs) and investigation of cytoplasmic streaming properties. Students are expected to register the propagation velocity of APs (found to be 3.4 ± 1.5 cm/s in N. obtusa), as well as the velocity of cytoplasmic streaming (66.7 ± 9 μm/s). Proposed exercises also concern recovery dynamics of cytoplasmic streaming after a stimulation (recovery time constant τ = 3.7 ± 2.1 min) as well as investigation of an effect of various chemicals (e.g., KCl) on all selected parameters. The experiments endorse characeaen algae as a model system to be routinely explored in education of biophysics and bioelectrical phenomena of the cell.

The commonest complication following hypospadias repair is occurrence of urethro-cutaneous
stula(UCF) with a reported incidence of 4-25% 1. The expected stula rate is between 10% to 15% for onestage hypospadias surgery. UCF after hypospadias repair remains a signicant challenge for paediatric surgeons despite the
advances in surgical techniques. Our aim is to assess the outcome of tunica vaginalis ap repair in cases of urethro-cutaneous
stula. Our study included 23 patients who underwent UCF repair using TVF. Successful repair of these UCF depends on several
basic principles, which are the avoidance of procedures on inamed tissue, correction of distal obstruction, a tension-free
urethral closure with absorbable suture material, and covering of the urethral repair with well-vascularized tissue. From our
study we feel that many complications mainly recurrent stula can be avoided using the above principles.

La regulación del teletrabajo en las administraciones públicas; en particular, la incidencia de la pandemia de la COVID-19
Authors: Villalba Sánchez Alicia
Published: April 2021

Menos permeables a la revolución tecnológica que las empresas privadas, las Administraciones Públicas han acusado el embate de la pandemia de COVID-19 dotadas de una regulación insuficiente. Desde que la propagación del SARS-CoV-2 hizo del distanciamiento social la medida de contención por excelencia, quedó en evidencia la necesidad de un marco jurídico capaz de amparar una migración flexible hacia modalidades no presenciales de prestación de servicios. En aras de la debida seguridad jurídica, el legislador estatal y autonómico han emprendido una senda reformista encaminada a dar cumplida respuesta a las necesidades coyunturales derivadas de la pandemia, pero también a articular el corpus normativo en cuyo seno se escenificará el tránsito definitivo hacia la administración digital.

La dictadura y la Constitución española de 1978
Authors: Vila Conde Francisco
Published: April 2021

La dictadura es un tabú en los regímenes liberal-positivistas. En ellos, el sustantivo dictadura solo es empleado para designar y denostar al enemigo político. Empero, esta vulgarización del término en nada contribuye al estudio de la dictadura como institución genuinamente jurídica. En este trabajo, analizamos la dictadura desde su dimensión jurídica en relación con un tema de actualidad -el COVID-19- y su posible encaje o no dentro del sistema constitucional de 1978 en situaciones de excepcionalidad. Para ello, se parte de la tipología schmittiana y la diferencia entre dictadura comisaria y dictadura soberana.
Derecho de manifestación en tiempos de pandemia
Authors: Ortega Carballo Carlos
Published: April 2021

La crisis sanitaria provocada por el Covid 19 ha puesto en riesgo el ejercicio de determinados derechos fundamentales; entre ellos, especialmente el derecho de manifestación cuyo ejercicio necesita, por definición, la presencia de varias personas en un determinado tiempo y lugar, lo que parecería contravenir las medidas básicas de protección frente a la pandemia. El equilibrio entre las medidas adoptadas para la lucha contra la enfermedad y el regular ejercicio de los derechos fundamentales es el reto que deben afrontar todos los actores implicados: autoridades públicas, jueces y tribunales, Tribunal Constitucional y Tribunal Europeo de derechos humanos. Nos encontramos en un momento clave, sin precedentes, en la defensa de los derechos fundamentales.
