On a two-fold cover 2.(2⁶˙G₂(2)) of a maximal subgroup of Rudvalis group Ru
Authors: Prins Abraham Love
Published: April 2021

The Schur multiplier M(Ḡ1) ≅4 of the maximal subgroup Ḡ1 = 2⁶˙G₂(2)of the Rudvalis sporadic simple group Ru is a cyclic group of order 4. Hence a full representative group R of the type R = 4.(2⁶˙G₂(2)) exists for Ḡ1. Furthermore, Ḡ1 will have four sets IrrProj(Ḡ1;αi) of irreducible projective characters, where the associated factor sets α1, α2, α3 and α4, have orders of 1, 2, 4 and 4, respectively. In this paper, we will deal with a 2-fold cover 2. Ḡ1 of Ḡ1 which can be treated as a non-split extension of the form Ḡ = 27˙G2(2). The ordinary character table of Ḡ will be computed using the technique of the so-called Fischer matrices. Routines written in the computer algebra system GAP will be presented to compute the conjugacy classes and Fischer matrices of Ḡ and as well as the sizes of the sets |IrrProj(Hi; αi)| associated with each inertia factor Hi. From the ordinary irreducible characters Irr(Ḡ) of Ḡ, the set IrrProj(Ḡ1; α2) of irreducible projective characters of Ḡ1 with factor set α2 such that α22= 1, can be obtained.

Authors: Salmieri Luca , Giancola Orazio
Published: April 2021

El objetivo de este breve análisis es ampliar el debate sobre la pobreza educativa y subrayar la importancia de asociar las intervenciones económicas de lucha contra la pobreza, como el Ingreso Mínimo Vital, a las políticas de reducción de la pobreza educativa. En este trabajo se compara la difusión de la pobreza educativa en España con otros países europeos (Alemania, Francia, Italia y Reino Unido), utilizando tres fuentes de datos: 1) la European Social Survey; 2) datos de la encuesta PIAAC sobre habilidades de adultos y 3) resultados de la OCDE-PISA 2018 relacionados con el menor rendimiento en lectura, matemáticas y ciencias de jóvenes de 15 años. Se recuerda la importancia de fortalecer las políticas contra la pobreza en una perspectiva multidimensional, para que las medidas de apoyo económico sean aún más incisivas, en términos de larga duración, si se vinculan estrechamente a esquemas de largo plazo dirigidos a mejorar las condiciones de empoderamiento de la población con severa privación educativa y en el área de habilidades sociales básicas.

Placing plant-soil feedbacks in the context of plant community growth
Authors: Grenzer Josephine , Kulmatiski Andrew , Forero Leslie , Ebeling Anne , Eisenhauer Nico , Norton Jeanette
Published: April 2021

1. Plant-soil feedback (PSF) has gained attention as a mechanism
promoting plant growth and coexistence. However, because most PSF
research has measured monoculture growth in greenhouse conditions,
field-based PSF experiments remain an important frontier for PSF
research. 2. Using a four-year, factorial field experiment in Jena,
Germany, we measured the growth of nine grassland species on soils
conditioned by each of the target species (i.e., PSF). Plant community
models were parameterized with or without these PSF effects, and model
predictions were compared to plant biomass production in new and
existing diversity-productivity experiments. 3. Plants created soils
that changed subsequent plant biomass by 36%. However, because they
were both positive and negative, the net PSF effect was 14% less growth
on ‘home’ than ‘away’ soils. At the species level, seven of nine species
realized non-neutral PSFs, but the two dominant species grew only 2%
less on home than away soils. At the species*soil type level, 31 of 72
PSFs differed from zero. 4. In current and pre-existing
diversity-productivity experiments, nine-species plant communities
produced 37 to 29% more biomass than monocultures due primarily to
selection effects. Null and PSF models predicted 29 to 28% more biomass
for polycultures than monocultures, again due primarily to selection
effects. 5. Synthesis: In field conditions, PSFs were large enough to be
expected to cause roughly 14% overyielding due to complementarity,
however, in plant communities overyielding was caused by selections
effects, not complementarity effects. Further, large positive and large
negative PSFs were associated with subdominant species, suggesting there
may be selective pressure for plants to create neutral PSF. Broadly,
results highlighted the importance of testing PSF effects in communities
because there are several ways in which PSFs may be more or less
important to plant growth in communities than suggested from simple PSF
values.
Thromboinflammation in COVID-19: The Clot Thickens
Authors: Iffah Raayma , Gavins Felicity
Published: April 2021

Since the start of the novel coronavirus SARS-Cov-2 pandemic, a disease
that has become one of the world’s greatest global health challenges,
the role of the immune system has been at the forefront of scientific
studies. The pathophysiology of COVID-19 is complex, which is evident by
those at higher risk for poor outcome. Multiple systems contribute to
thrombosis and inflammation seen in COVID-19 patients, including
neutrophil dysfunction, platelet activation, endothelial cell
activation. Understanding how the immune system functions in different
patient cohorts (particularly given recent emerging events with the
Oxford/AstraZeneca vaccine) is vital to understanding the
pathophysiology of this devastating disease and for subsequent
development of novel therapeutic targets and expedite possible drug
repurposing strategies that could benefit society on a global scale.
Initial Report of a New Suture Cerclage Tape for Sternal Closure
Authors: DiGiorgi Paul
Published: April 2021

PURPOSE: We sought to evaluate a new, flexible suture cerclage tape for
sternal closure after cardiac surgery. DESCRIPTION: Fiber Tape (Arthrex,
Naples, FL, USA) suture cerclage has been successfully utilized in the
stabilization of long bone fractures. For sternal closure, it is placed
similarly to wire cerclage. Uniquely, it allows a measurable amount of
tension to be applied to the sternum and it is at least twice as strong
as stainless steel wire. We hypothesized this new flexible tape would
provide short term safety and efficacy, as measured by incidence of deep
sternal wound infection. EVALUATION: We performed a retrospective,
single center analysis of adult patients undergoing sternotomy closure
with FT. The observed incidence of deep sternal wound infection (DSWI)
was compared to the expected incidence calculated through the Society of
Thoracic Surgery (STS) risk calculator. A total of 45 patients were
closed with FT. No patients suffered DSWI. Thirty of the 45 patients had
STS risk calculations. For these 30 patients, the expected rate of DSWI
was 0.2%. CONCLUSIONS: Despite study limitations, FT appears to be a
safe method for sternal closure.
Capture by hybridization for full-length barcode-based eukaryotic and prokaryotic biodiversity inventories for deep sea ecosystems
Authors: Günther Babett , MARRE Sophie , Defois Clémence , Merzi Thomas , Blanc Philippe , PEYRET Pierre , Arnaud-Haond Sophie
Published: April 2021

Biodiversity inventory remains limited in marine systems due to
unbalanced access to the three ocean dimensions. The use of
environmental DNA (eDNA) for metabarcoding allows fast and effective
biodiversity inventory and is forecast as a future biodiversity research
and biomonitoring tool. However, in poorly understood ecosystems, eDNA
results remain difficult to interpret due to large gaps in reference
databases and PCR bias limiting the detection of some major phyla. Here,
we aimed to circumvent these limitations by avoiding PCR and
recollecting larger DNA fragments to improve assignment of detected taxa
through phylogenetic reconstruction. We applied capture by hybridization
(CBH) to enrich DNA from deep-sea sediment samples and compared the
results with those obtained through an up-to-date metabarcoding
PCR-based approach (MTB). Originally developed for bacterial communities
by targeting 16S rDNA, the CBH approach was applied to 18S rDNA to
improve the detection of species forming benthic communities of
eukaryotes, with particular focus on metazoans. The results confirmed
the possibility of extending CBH to metazoans with two major advantages:
i) CBH revealed a broader spectrum of prokaryotic, eukaryotic, and
particularly metazoan diversity, and ii) CBH allowed much more robust
phylogenetic reconstructions of full-length barcodes with up to 1900
base pairs. This is particularly important for taxa whose assignment is
hampered by gaps in reference databases. This study provides a database
and probes to apply 18S CBH to diverse marine systems, confirming this
promising new tool to improve biodiversity assessments in data-poor
ecosystems like those in the deep sea.
Vascular Expression of Permeability-Resistant Occludin Mutant Preserves Visual Function in Diabetes

Published: April 2021

Diabetic retinopathy is one of the leading causes of vision loss
and blindness. Extensive pre-clinical and clinical evidence exists for both
vascular and neuronal pathology. However, the relationship of these changes in
the neurovascular unit and impact on vision remains to be determined. Here, we
investigate the role of tight junction protein occludin phosphorylation at S490
in modulating barrier properties and its impact on visual function. Conditional
vascular expression of the phosphorylation resistant Ser490 to Ala (S490A) form
of occludin preserved tight junction organization and reduced VEGF-induced
permeability and edema formation after intra-ocular injection. In the retinas
of streptozotocin-induced diabetic mice, endothelial specific expression of the
S490A form of occludin completely prevented diabetes-induced permeability to
labeled dextran and inhibited leukostasis. Importantly, vascular-specific
expression of the occludin mutant completely blocked the diabetes-induced
decrease in visual acuity and contrast sensitivity. Together, these results
reveal that occludin acts to regulate barrier properties downstream of VEGF in
a phosphorylation dependent manner and that loss of inner blood-retinal barrier
(iBRB) integrity induced by diabetes contributes to vision loss.

Published: April 2021

In this study, deviations for the porosity level of the Ti-6Al-4V functionally graded porous structures for three different cell structures were investigated. For this purpose, functionally graded porous structures are designed and produced by selective laser melting (SLM). It is also aimed to investigate the effects of unit cell structure, unit cell size, and column (strut) thickness on the porosity deviation level. The specimens were scanned at micro-computed tomography (micro-CT) to determine the structure dimensions after production. According to the results obtained from micro-CT, an average increase of 150-300 μm was observed on the column thicknesses of all functionally graded porous structures. It has been observed that the horizontal columns of cubic and octagonal structures have sagging due to metal melting during production. It has been determined that the porosity of the manufactured parts was deviated between 5.71%-10.54% for cubic, 8.59%-12.39% for octahedroid, and 13%-16.49% for diamond structures compared to the design values.

A mycotoxin is the greatest concern in the case of dried herbs, due to their low water activity, microbial contamination may persist in these products, and thus, herbs can be sources of outbreaks of foodborne diseases. The toxigenic fungal compounds called mycotoxin are poisonous substances produced by different species of fungus. Three major genera of fungus are identified to produce mycotoxins: they include Aspergillus, Fusarium, and Penicillium. Although other genera also produce these toxigenic compounds. The presence of mycotoxins in dried herbs poses health risks ranging from mild to severe damage to the liver and kidney. Fungal toxicity could be prevented by controlling the environmental condition that influences fungal growth, which is by controlling the physical conditions of the dried herbs and by the use of mold inhibitors and anti-cracking additives. The control of the toxigenic compounds could also be by removing the suspected dried herbs with a fungal toxin or by the addition of the toxin binder to the ratio of the dried herbs.

Objetivo do estudo: Objetiva-se compreender como o comportamento e a ação do gestor frente ao risco influenciam e moldam os processos de internacionalização. Metodologia/abordagem: Realizou-se um estudo de meta-síntese de estudos de caso qualitativos envolvendo de maneira conjunta a influência do gestor e a ação em relação ao risco.Originalidade/Relevância: A literatura reconhece que as diferentes relações que se estabelece com o risco podem fazer com que os gestores superestimem ou subestimem as situações. Porém, há poucas evidências empíricas de como o comportamento do gestor frente a essas situações modifica suas escolhas estratégicas e seus antecedentes, sendo significativo um estudo enfatizando o nível individual.Principais resultados: Pode-se afirmar que o gestor e seu background influenciam no envolvimento e desenvolvimento organizacional ao longo do processo de internacionalização. Ainda é possível destacar que existe um antecessor à ação ao risco, a qual é a percepção dos riscos. Além disso, depreende-se que as características cognitivas destes gestores também devem ser consideradas quando analisado sua percepção de riscos.Contribuições teóricas/metodológicas: Como contribuição da pesquisa, sugere-se que a ação do gestor frente ao risco seja complementada por sua percepção acerca do risco. Acredita-se que com esta perspectiva de percepção de riscos, as pesquisas na área podem ampliar o escopo teórico de explicação, onde essa percepção se apresenta como um antecessor e um frame às futuras decisões e ações.

El objetivo de la investigación fue determinar los niveles de proteína C- Reactiva antes y después del tratamiento periodontal no quirúrgico en gestantes con periodontitis en el Instituto Nacional Materno Perinatal.  Para el periodontograma se utilizó la sonda periodontal UCN Probe 1-15 Hu Friedy. Para el IG se utilizaron  las piezas dentarias 1.6, 2.1, 2.4, 3.6, 4.1 y 4.4; en cada pieza dentaria se valoró la inflamación de cuatro zonas gingivales (mesial, vestibular, distal y lingual) y se le asignó un valor de 0 a 3; donde 0 indica que es una encía normal, 1 indica inflamación leve con cambio leve de color y edema ligero, sin hemorragia al sondeo; 2 indica inflamación moderada con enrojecimiento, edema, brillo y hemorragia al sondeo y 3 indica Inflamación intensa con enrojecimiento, edema intensos, ulceración, encontrándose en las gestantes con gingivitis y periodontitis localizada se distribuyen igual con respecto a paridad (50% primigestas y 50% multigestas) y . En los promedios pos tratamiento de sangrado gingival e higiene bucal en gingivitis y periodontitis, el p-valor asociado es menor a 0,05. En conclusión, se encontró que las gestantes con gingivitis y periodontitis localizada se distribuyen igual con respecto a paridad y edad; las gestantes con gingivitis presentan menor edad gestacional.
ABSTRACT
The objective of the research is to determine the levels of C-Reactive protein before and after the non-surgical periodontal treatment in pregnant women with periodontitis in the National Maternal Perinatal Institute. The periodontal probe UCN Probe 1-15 Hu Friedy was used for the periodontogram. For the GI dental pieces were used 1.6, 2.1, 2.4, 3.6, 4.1 and 4.4; in each dental piece the inflammation of 4 gingival zones (mesial, vestibular, distal and lingual) was assessed and assigned a value of 0 to 3; where 0 indicates that it is a normal gingiva, 1 indicates mild inflammation with slight change in color and slight edema, without hemorrhage when probing; 2 indicates moderate inflammation with redness, edema, brightness and hemorrhage when probing and 3 indicates intense inflammation with redness, intense edema, ulceration, being found in pregnant women with localized periodontitis and gingivitis are distributed equally with respect to parity (50% primigraves and 50% multigesta) and. In the averages after treatment of gingival bleeding and oral hygiene in gingivitis and periodontitis, the associated p-value is less than 0.05. In conclusion, it wasfound that pregnant women with gingivitis and localized periodontitis are distributed equally with respect to parity and age; pregnant women with gingivitis have a lower gestational age.
Keywords: Pregnant with gingivitis and periodontitis.

Se diagnosticó la percepción sobre la contaminación ambiental de la publicidad objetiva de origen público y privado en el Perú. Se utilizó una encuesta semiestructurada de 20 preguntas que estuvo compuesta de tres dimensiones: información primaria, impactos y consecuencias ambientales, y medidas de control. La muestra fue de 1200 personas y se desarrolló del 20 de mayo al 06 de junio del 2019. Los encuestados consideran a los letreros por campañas políticas como la peor forma de contaminación visual. Los grafitis tienen un impacto ambiental en las ciudades, generando pésima imagen. Los letreros digitales de propaganda, generan impactos asociados con el resplandor y distracción de las personas, y los afiches son elementos contaminantes. La publicidad afecta su concentración, y les genera distracción provocándole alteración de sus sentidos, causándoles mal humor y cambios en su estado de ánimo, e incrementa sus niveles de estrés. También, consideran que la contaminación visual tiene impacto sobre su campo visual. La publicidad, genera una mala imagen. Para la dimensión de medidas de control, se muestran a favor de implementar normas legales que regulen la publicidad, acompañado de fiscalizaciones para restringir la exagerada publicidad. Las alternativas de publicidad son la digital y por redes sociales. Finalmente, se concluye que la población, considera a la publicidad, como elementos de alto impacto visual, generando consecuencias con potencial afección a su salud y al ambiente, generando mala imagen a una ciudad. La falta de normas legales y tecnologías modernas en la actualidad, genera una exacerbada publicidad en las ciudades.

Se describe el diseño de cuatro trampas evaluando su actividad para la captura de decápodos con especial énfasis en cangrejos, camarones y langostas de agua dulce, con el fin de comprobar su efectividad y estandarizar el método de colecta indirecta en Colombia. Se llevó a cabo una revisión bibliográfica, en la cual se encontraron aspectos relacionados a las trampas que en la actualidad se utilizaban para la recolección de todo tipo de crustáceos dulceacuícolas, en estos se generó un enfoque acerca de los diversos estudios realizados en pesca experimental retomando algunos aspectos metodológicos para llevar a cabo la construcción de las trampas, las cuales fueron: Trampa de cilindro modificada; Trampa tipo mochila-Martin; Trampa tipo canasta y Trampa tipo cono, estas se crearon y modificaron en el presente estudio. Para evaluar su efectividad, se realizaron diferentes pruebas en campo, como es, la eficiencia de recolección de cada trampa en una zona del cuerpo de agua, bien sea lentica o lotica, la ubicación de estas, y la recolecta final; estas se realizaron tanto en las horas de la mañana, tarde y noche en diferentes escenarios. Proponiendo así, una estandarización respecto a los métodos de colecta indirectos en decápodos dulceacuícolas que contribuyen a estudios taxonómicos, biológicos, ambientales y distribucionales de cangrejos, camarones y langostas. Descripciones, fotos, y diseños son presentados. Los resultados de este trabajo contribuyen a posteriores estudios acerca de la biodiversidad y biología de cangrejos, camarones y langostas, con énfasis en los de hábitos dulceacuícolas. Respecto a la utilización de trampas, todas poseen una efectividad evidente, siendo importante tener en cuenta los tipos de cuerpos de agua donde se utilicen.
