Published: March 2023

Acinetobacter baumannii (A. baumannii) is one of the most common clinical pathogens and a typical multi-drug resistant (MDR) bacterium. With the increase of drug-resistant A. baumannii infections, it is urgent to find some new treatment strategies, such as phage therapy. In this paper, we described the different drug resistances of A. baumannii and some basic properties of A. baumannii phages, analyzed the interaction between phages and their hosts, and focused on A. baumannii phage therapies. Finally, we discussed the chance and challenge of phage therapy. This paper aims to provide a more comprehensive understanding of A. baumannii phages and theoretical support for the clinical application of A. baumannii phages.

Published: March 2023

Although the global Zika epidemic in 2015–16 fueled vaccine development efforts, there is no approved Zika vaccine or treatment available to date. Current vaccine platforms in clinical trials are administered via either subcutaneous or intramuscular injections, which are painful and decrease compliance. Therefore, in the present study, we explored Zika vaccine microparticles (MPs)-loaded dissolving microneedles (MNs) with adjuvant MPs encapsulating Alhydrogel® and MPL-A® administered via the transdermal route as a pain-free vaccine strategy. We characterized the MNs for needle length, pore formation, and dissolvability when applied to murine skin. Further, we evaluated the in vivo efficacy of vaccine MPs-loaded MNs with or without adjuvants by measuring the immune response after transdermal immunization. The vaccine MPs-loaded dissolving MNs with adjuvants induced significant IgG, IgG1, and IgG2a titers in immunized mice compared to the untreated control group. After the dosing regimen, the animals were challenged with Zika virus, monitored for seven days, and sacrificed to collect spleen and lymph nodes. The lymphocytes and splenocytes from the immunized mice showed significant expressions of helper (CD4) and cytotoxic (CD8a) cell surface markers compared to the control group. Thus, this study puts forth a ‘proof-of-concept’ for a pain-free transdermal vaccine strategy against Zika.

Published: March 2023

Canine hemangiosarcoma is a common, highly fatal tumor of older dogs, and predictors of survivability may provide clinically useful information. The objectives of this case series were to determine if a previously published tumor histological grading scheme, the level of tumor cellular atypia, clinical staging, or the level of CD 31 expression were useful for predicting the survival time in dogs with splenic hemangiosarcoma. Canine splenic hemangiosarcomas from 16 dogs were histologically graded, clinically staged, and assessed for CD 31 expression. Medical records were reviewed, the date of death was obtained, and survival data were analyzed statistically. Histopathological grading and clinical staging of canine splenic hemangiosarcomas, and the expression of CD 31 by the tumor cells were not significantly associated with the median survival time of the dogs in this study. However, strong expression of CD 31 by canine splenic hemangiosarcoma tumor cells was observed in dogs with short survival times, which warrants further studies to evaluate the potential prognostic value of CD 31 expression for the survival of dogs with splenic hemangiosarcoma.

Published: March 2023

The objective of this study is to evaluate the contamination of water resources in the Parac subbasin. The existing contamination by heavy metals due to the presence of mining companies is of great concern to the population that inhabits the area since health is being affected. A methodology has been used as an integrated approach based on pollution assessment indices. Five surface water samples and seven groundwater samples were collected in the Parac subbasin, in the vicinity of the Tamboraque tailings. Physicochemical parameters and heavy metals (Al, As, Br, Pb, Fe, Cd, Mn, Hg, B, Ni, Cu, and Se) were analyzed. The mean concentrations of Al, As, Ba, Cu, Fe, Pb, and Zn were 0.3 mg/L, 0.02 mg/L, 0.02 mg/L, 0.05 mg/L, 0.8 mg/L, 0.04 mg/L, and 0.12 mg/L respectively. HPI, HEI, and Cd indices were averaged around 1378.5, 134.5, and 126.5 respectively, HPI and Cd values were above 100 as a critical contamination index value, which indicates that the water samples are critically contaminated with respect to the heavy metals studied. The total variance was 88.11% of the water quality with two components according to the ACP analysis. Al, As, Cu, Fe, Pb, Zn, and Mn showed a high positive charge on PC1 (69.68%) while Ba and Mo had a high positive charge on PC2 (18.12%). The intensity of distribution of metals As, Fe, Mn, and Pb in surface and groundwater is an environmental concern and a more complete monitoring network is needed for the sustainable management of water resources.

Published: March 2023

Despite keen interest in the development of efficient materials for the removal of polycyclic aromatic hydrocarbons (PAHs) in wastewater, the application of advanced composite materials is still unexplored and needs attention. Therefore, this study focused on the synthesis of the composite of oil palm leaves’ waste activated-carbon (OPLAC) and nano zerovalent iron (NZVI) at Fe:OPLAC = 1:1 (N-OPLAC-1) and 1:2 (N-OPLAC-2). The composite with enhanced surface properties was applied for removal of three PAHs including naphthalene (NAP), fluorene (FLU) and phenanthrene (PHE) in wastewater at various pH, dosages, contact time and initial concentration in batch testing. The PAHs’ removal parameters were optimized using design expert software. The PAHs’ removal efficiency was evaluated in produced water at optimized parameters. The results showed that the N-OPLAC-2 had superior surface properties compared to N-OPLAC-1. The removal of NAP, FLU and PHE was heterogenous, favorable and involved chemisorption proved by Freundlich isotherm and pseudo-second-order kinetic models using N-OPLAC-2. The optimum parameters were as follows: pH of 3, dosage and contact time of 122 mg/L and 49 min, respectively. The application of N-OPLAC-2 in produced water was favorable for removal of NAP, FLU and PHE and showed up to 90% removal efficiency, and higher stability up to 3 cycles. It can be concluded that the NZVI-OPLAC composite was successfully synthesized in this study and the materials showed good removal efficiency for three PAHs (NAP, FLU and PHE) in wastewater.

Published: March 2023

Artificial reclamation is one of the main means of land expansion in coastal cities. However, the permeability of underlying soft clay (USC), derived from the dredged load, has not been paid enough attention, although it is closely related to the long-term deformation and stability of foundation soil. Hence, this paper analyzes the relationship between permeability characteristics and microscopic pore characteristics of USC in Chongming East Shoal (CES), a typical multi-phase reclamation area, through a variable head permeability test, mercury intrusion porosimetry (MIP) test, and scanning electron microscope (SEM) test. Furthermore, grey relation entropy and Pearson correlation analysis are implemented to analyze the influence of micropore parameters on permeability. The results revealed that the seepage process of clay showed a transition from unstable seepage to relatively stable seepage. Meanwhile, the permeability coefficient (PC) attenuated with time cyclically, indicating the alternating effect of the closed and opened unstable seepage channels. During seepage, clay particles could be entrained by pore water and intercepted by pores, thus clogging seepage channels. Then, the increased pore water pressure could break through new seepage channels. The degree of pore clogging was positively correlated with the average cycle period of PCs, and this was also present in the relatively stable stage of PCs. A lower mesopores content, higher fractal dimension, and aggregated flocculate microstructure could promote the clogging effect and result in lower permeability efficiency. Affected by unstable seepage channels, soft clay may face long-term potential deformation in the future, which needs further investigation.
Impact of Antibiotic Pollution on the Bacterial Population within Surface Water with Special Focus on Mountain Rivers

Published: March 2023

Environmental aquatic pollution with antibiotics is a global challenge that affects even pristine mountain environments. Monitoring the concentration of antibiotics in water is critical to water resource management. In this review, we present the sources and degradation routes of antibiotics polluting surface waters, with particular focus on mountain environments and pristine areas. This pollution is strongly related to anthropopressure resulting from intensive tourism. An important aspect of the threat to the environment is water containing antibiotics at sub-inhibitory concentrations, which affects bacterial populations. Antibiotics are ecological factors driving microbial evolution by changing the bacterial community composition, inhibiting or promoting their ecological functions, and enriching and maintaining drug resistance. We paid attention to the stability of antibiotics and their half-lives in water related to biotic and abiotic degradation, which results from the structures of molecules and environmental conditions. Wastewater treatment combined with advanced treatment techniques significantly increase the efficiency of antibiotic removal from wastewater. Modern methods of wastewater treatment are crucial in reducing the supply of antibiotics to aquatic environments and enhancing the possibility of economic and safe reuse of wastewater for technical purposes. We provide a perspective on current research investigating antibiotic emergence in mountain areas and identify knowledge gaps in this field.

Este trabajo tiene como objetivo investigar el vínculo entre la imagen óptico-sonora pura y el Aión. Para ello, se propone como hipótesis principal la situación óptica-sonora pura es el puntapié inicial para adquirir una imagen directa del tiempo. En efecto, dicha imagen sería la del Aión, base del tiempo cronológico. La situación óptico-sonora pura describe el momento en el que ya no hay percepción seguida de acción, dando lugar a la percepción de la interioridad del tiempo fundamental. Por lo tanto, se sostiene aquí que lo visto en la imagen óptico-sonora pura es el tiempo Aión o tiempo del acontecimiento.
El concepto de representación en la República de Weimar
Authors: Senigaglia Cristiana
Published: March 2023

Este artículo pretende clarificar el concepto de representación y delimitar la discusión que se produjo durante los tiempos de la República de Weimar. A estos fines, la autora examina las contribuciones que realizaron cuatro de los más significativos teóricos de la representación de la época. En primer lugar, atiende la contraposición entre representación libre y representación vinculada que estableció Max Weber. Seguidamente, muestra el giro que cobró con Carl Schmitt, al momento en que identifica la representación con la figuración y personificación de ideas o principios políticos. En tercer lugar, trata el rol simbólico que, de acuerdo con Rudolf Smend, la representación cumple en la integración y formación de la unidad política. Por último, se pone en consideración el vínculo de la representación política con la voluntad popular y, particularmente, con las condiciones sociales del pueblo que enfatiza Heller. A grandes rasgos, el artículo ofrece una visión panorámica de la discusión teórica sobre la representación política y de los aspectos que fueron subrayados por los teóricos del Estado de Weimar.

Authors: ROBLES-JARERO Elva Guadalupe , PÉREZ-PEÑA Martín
Published: March 2023

Phytoplankton biomass (Chl-a) was estimated in 7 stations of Manzanillo Bay, Colima on the surface and at the Secchi depth in the rainy and dry season (2016-2017). To evaluate the biomass, a Millipore equipment and fiberglass GF / F filters were used using the spectrophotometric technique (Lorenzen, 1967). The physicochemical parameters were estimated with a YSI 85 equipment and the nutrients using a San Plus II segmented flow autoanalyzer. The average depth of the Secchi disk ranged from 5.9 m at the Puerto station to 12.8m at the center (A1 and A2). The temperature ranged from 26.9 to 28.1 ° C, the salinity between 31.6 and 33 ups and the dissolved oxygen from 3.81 to 4.82 mg L-1. The nutrients presented high values in Puerto, A1 and Carrizales. The central part of the bay registered values greater than one mg of Chl-a and a maximum of 2.67 mg .m-3 in the Puerto station. In 2016, Chl-a decreased significantly because of a very intense Niño event, also showing high concentrations of phaeopigments, which reveal grazing conditions or degraded chlorophyll. Through an analysis of variance, it was determined that there is a significant difference between the chlorophyll-a values (p≤0.05).

The present study shows the distribution of alien fish species in tropical lakes in the middle Doce river basin, southeastern Brazil, obtained from a rapid assessment program. The causes for their introductions were sportfishing improvement in some specific lakes and aquaculture in the studied basin. Presently, these species have a wide distribution occurring in 41 of the 54 lakes studied, representing an actual threat to regional native fish community. The natural connection among lakes and streams during the rainy season and the dispersal mediated by local people are the main invasion agents for alien fishes. The success of these invaders is probably due to absence of pre-existing effective competitors or top-predators in the invaded communities. We consider that the eradication of alien fishes by means of the available management tools may be very difficult due to the large number of lakes invaded and to the wide spectrum of lake conditions and resources exploited by these alien species. We recommend the use of environmental education as a tool to stop the human-mediated dispersion of aliens and to improve conservation of native fish community in lakes where these alien species are not present yet.

Pseudoscorpions have the ability to attach themselves to a wide variety of more mobile arthropods. This interaction has been termed phoresy. We report on a phoretic interaction of Semeiochernes armiger with a giant tropical fly Pantophthalmus tabaninus in an Amazonian rain forest. Two males and two females of S. armiger were found attached to the right posterior leg of the fly. In addition, more than two hundred mites were found on the thorax of the host fly. Long term and detailed studies on the phoretic associations of pseudoscorpions and hosts in the neotropical rain forest would contribute to a better understanding of these interactions.

The objective of this work was to describe the morphology of the insect galls occurring in Miconia prasina (Melastomataceae) and their yearly frequencies in four remnants of Atlantic forest in northeastern Brazil. In each study area young individuals up to 2 m were marked and observed monthly for the number of galls. The leaf-galling insects induced elliptic, spherical and fusiform types in the leaf blade of M. prasina growing at four studied fragments; a cylindrical type in Refúgio Charles Darwin; and a piriform type in the axillary bud in the Cachoeira and Capoeirão fragments. In the selected individuals 1131 new galls were counted along a year. Of these, 548 were elliptic, 336 spherical, 125 fusiform, 81 cylindrical and 41 piriform. The gall inductors were generally registered in larger numbers in the most humid months. The results of this study contribute to increase the knowledge of Neotropical galls diversity.

The galling insect community in a disturbed area of Atlantic rain forest is described for the first time in the context of environmental restoration in the RPPN Fazenda Bulcão, Minas Gerais, Brazil. We provide information on the external morphology of the galls, their occurrence on host plant organs, host plant species, and habitat types were they were collected. We sampled galls in three different habitats: abandoned pasture, secondary succession vegetation, and secondary succession vegetation dominated by Miracruodon urundeuva (Anacardiaceae), totaling 22 sites. Within these sites we encountered 29 gall morphotypes associated to 24 host-plant species. The majority of the galls (93%) were induced by Cecidomyiidae (Diptera). Abandoned pastures contained the greatest gall-species richness (19 morphotypes), followed by secondary succession vegetation dominated by M. urundeuva (16 morphotypes) and secondary succession vegetation (10 morphotypes). The diversity of galling insects encountered at Fazenda Bulcão was considered very low in comparison to that of the entire mid Rio Doce region.

Published: March 2023

The dusky-legged guan, Penelope obscura Temminck, 1815, is a threatened bird species in Minas Gerais, southeastern Brazil. In this paper, observations on the reproduction of this species in the southern Espinhaço Range are reported. We found chicks and immatures of P. obscura during the rainy season, between November and January. Based on the development of gonads of two collected specimens, and given that incubation spends 28 days, nesting should occur between October and November. These are the first observations on the breeding of the subspecies P. obscura bronzina in the wild.

The taxonomic information on the species of Eulaema Lepeletier, 1841 is updated. Three of the species recently described by Moure — E. pallescens Moure, 2000, E. stenozona Moure, 2000 and E. helvola Moure, 2000 — are synonymized with E. meriana (Olivier, 1789), E. terminata (Smith, 1874) and E. seabrai Moure, 1960, respectively. Two species revalidated by Moure (2000), E. quadrifasciata (Friese, 1903) and E. niveofasciata (Friese, 1899), are considered synonyms of E. meriana (Olivier, 1789) and E. bombiformis (Packard, 1869), respectively. Besides, E. mimetica Moure, 1967 is considered a synonym of E. tenuifasciata (Friese, 1925). Additions to the catalogue by Moure (2000) include Eulaema sororia Dressler & Ospina-Torres (1997) and E. chocoana Ospina-Torres & Sandino-Franco (1997), which were not mentioned by Moure (opus cit.), and E. napensis Oliveira, 2006, E. parapolyzona Oliveira, 2006 and E. pseudocingulata Oliveira, 2006, described after the publication of his catalogue. Lectotypes of E. boliviensis Friese, 1898, E. bomboides (Friese, 1923), E. polyzona (Mocsary, 1897) and E. tenuifasciata (Friese, 1925) are designated. Comments on the known geographic distributions of the 25 regonized species and maps illustrating them are also presented.

Keywords: Neotropics, orchid-bees, taxonomy, geographic distribution, lectotype designation.

Sulle orme dell'Iliade
Authors: Cannizzaro Francesco
Published: March 2023

Tradizionalmente la poesia epica d’età flavia è stata studiata in rapporto all’Eneide virgiliana; questo volume, invece, si sofferma sulla ricezione in Argonautiche, Tebaide e Punica di quattro grandi episodi dell’Iliade legati alla dimensione dell’eroismo. Omero non è soltanto archetipo della virtus, talora arcaica e primitiva, messa in campo dai protagonisti dei poemi esaminati, ma è usato persino come modello delle perversioni e della negazione della virtus stessa. Il volume, che evidenzia affinità e differenze tra Valerio Flacco, Stazio e Silio Italico in rapporto alla tecnica poetica e all’uso dei modelli, spazia lungo l’arco della poesia epica fino al I sec. d.C. e affronta anche questioni di cronologia relativa, piuttosto spinose specialmente per quanto riguarda Tebaide e Punica.

Qué ves cuando las ves. Las mafias italianas en los paisajes lingüísticos de la Ciudad de Buenos Aires
Authors: Balsas María Soledad , Capelli Francesca
Published: March 2023

In this article we question the visual references to the Italian mafias in the linguistic landscapes in the City of Buenos Aires, through a discursive and ethnographic approach. By analyzing the thematic, rhetorical and enunciative features deployed by the textual surfaces that circulate in public and/or virtual spaces, as well as some significant absences, we aim at problematizing the visual common sense that shapes our individual and collective perceptions on mafia. Due to the proliferation of those visualities and their tendency to spectacularization of the phenomenon of mafias, they would result in a «gaslighting» which tends to naturalize a poorly informed (if not openly biased) interpretation, which paradoxically hides more than what it shows.
50 años de La maffia (1972), de Leopoldo Torre Nilsson: representaciones de la mafia ítalo-rosarina. Interacciones entre narrativas periodísticas, literarias y cinematográficas
Authors: Setton Román Pablo
Published: March 2023

The following article analyzes the film La maffia (1972), by Leopoldo Torre Nilsson. I try to show how the film configures a representation of the Sicilian mafia of the 1930s less from the historical facts than from the speech of the journalistic chronicle of the time, of the Hollywood and Argentine cinematographic tradition and also from the literary tradition and the political imaginary linked to Peronism. In turn, the film itself – enormously successful with critics and audiences alike – goes on to feed the Argentine imaginary of that mafia, which continues to operate largely as an important influence on the political imaginary.
