Characterization Of Phyto-Synthesized Silver Nanoparticles And Their Antimicrobial Activity Against Diabetic Foot Ulcer Bacterial Isolates.
Authors: Chhajed Shweta  , Arora Asha
Published: November 2021

Diabetic Foot Ulcer (DFU) is one of the major complications of Diabetes. Patients with Diabetic Foot ulcers have a high susceptibility to microbial infections and are the leading cause of hospitalization and amputation of lower limbs. In the era of increased prevalence of bacterial resistance and outbreak of resistant infectious diseases, it is very essential to develop effective therapeutic strategies towards multi-drug resistant pathogens. The antimicrobial properties of silver nanoparticles have been well studied, therefore their use in biomedicine and pharmacology is a trend. Herein we present the use of Phyto-mediated synthesized AgNPs for the treatment of diabetic foot ulcers by topical administration. The nanoparticles were synthesized by reducing silver nitrate   using   Terminalia   chebula   fruit   extract.   The   nanoparticles   were   analyzed   and   characterized   using   UV-Visible Spectrophotometer,  FTIR,  XRD,  SEM  with  EDAX,  TEM,  and  DLS.  The  synthesized  silver  nanoparticles  were  assayed  for antimicrobial  activity  against  five  Diabetic  Foot  Ulcer  bacterial  isolates  i.e.  Escherichia  coli,  Klebsiella  Pneumoniae,  Pseudomonas aeruginosa, Streptococcus aureus, and Bacillus subtilis. The bactericidal property of synthesized nanoparticles was analyzed by the Agar well diffusion method, which revealed the remarkable antimicrobial effects against all the selective pathogenic bacterial isolates of Diabetic foot ulcers in the present study.   These results constituted the basis for further studies on the use of plant-based silver nanoparticles for the treatment of Diabetic Foot ulcers from different origins.
Effect Of Fruit And Cork Extract Of Ficus Lacor Buch Ham On α/β -Glucosidase, α -Amylase, Lipase, Glucose Absorption And Uptake
Authors: Mule V. S  , Naikwade N. S
Published: November 2021

Fruits of the plant Ficus Lacor Buch. Ham. were used traditionally for treatment of diabetes mellitus. The present study was undertaken to evaluate the antidiabetic potential of the plant using in vitro approach. Effect of Ficus Lacor Buch. Ham. was evaluated using α/β -glucosidase, α-amylase and lipase enzyme inhibition assay methods. The glucose absorption in intestine was evaluated using everted rat jejunum while glucose uptake was evaluated using isolated rat hemidiaphragm. Fruit and cork ethanolic extract was prepared by using soxhlation extraction method. In vitro assay of α-glucosidase showed that IC50  value of fruit extract was 83.03 µg/ml and cork extract 88.32 µg/ml when compared with control group acarbose. β-glucosidase enzyme was inhibited by fruit and cork extract of plant with IC50 value of fruit and cork extract 132.71 µg/ml and 171.93 µg/ml. The extracts further quantify α-amylase inhibitory activity of fruit (IC50  77.93 µg/ml) and cork (IC50  111.94 µg/ml) extract. Lipase inhibitory assay indicated the effect of plant extract on lipase enzyme was not prominent when compared to orlistat. Absorption of glucose through everted rat jejunum was reduced significantly (P ? 0.05) when compared with standard metformin. Effect of fruit and cork extract on rat hemidiaphragm exhibited significant (P ? 0.05) increase in glucose uptake when compared with standard metformin. Result suggests Ficus Lacor Buch. Ham. is effective in inhibiting carbohydrate metabolizing enzymes α/β –glucosidase and α-amylase while lipase enzyme was not affected. Fruit and cork extract of the plant was found to reduce significantly glucose absorption in everted rat jejunum. The significant increase in glucose uptake was observed in isolated rat diaphragm. The result reveals that Ficus Lacor Buch. Ham. acts by inhibiting carbohydrate metabolizing enzymes, reducing glucose absorption in intestine and increasing glucose uptake in hemidiaphragm.

Scientific and practical journal as territory of meanings
Authors:   Belarusian State University, BARANOVA ELENA
Published: November 2021

The article examines the communicative capabilities of a scientific and practical journal to describe phenomena and events, as well as explaining their semantic meaning. The author uses methods of content analysis of publications through their semantic context. Initially, the embedded interpretation of reality gives rise to a semantic dialogue between the reader and the creator of text. This form of text interactivity allows to obtain not only quantitative but also qualitative analysis results. The Belarusian scientific and practical journal “Problems of Management” was chosen as the object of analysis. As the analysis has shown, the semantic context of the published articles shows the direction for social development aimed at increasing the activity of the population and its responsibility for the quality of life. The author systematizes the semantic accents found in the interpretations. They are considered as a unity of three aspects. Socialization of economic transformation is understood as the creativity and entrepreneurial spirit among producers. Social policy modifications are considered to stimulate human capital and direct everyone towards personal effectiveness. Social dialogue is regarded as a format of civic participation in the public administration system. In this context, the scientific knowledge provided by the magazine about the adaptation of Belarusian society to the changes and challenges of time is perceived. This allows the author to qualify the processes taking place in the country as secondary socialization, during which society acquires new features without losing its basic characteristics. In turn, the activities of the journal can be defined as having inclusive nature: the journal is integrated into the management process by explaining to the reader the meanings of the guidelines set by the state.
Taxation judge and social interaction: is participation possible and what does it involve?
Authors:   Côte d’Azur University, LUPPI PHILIPPE
Published: November 2021

The article focuses on the role and place of a taxation judge in the French legal system. The author notes that the activity of a judge in tax disputes is not regulated by any special act; it is self-independent and, at the same time, ensures compliance with the general principles of private or public law. The taxation judge seeks a balance in the delicate relationship between the tax administration and the taxpayer, where the latter perceives the tax as a burden rather than civic duty, and sometimes tries to violate the rules and the law, forgetting that, as Oliver Holmes said, “Taxes are the price we pay for the opportunity to live in a civilized society”. Many taxation mechanisms are balancing on the verge of legality and get out of the control of a judge who does not always have sufficient information and resources. Despite the progress made in this area, taxation judges have not been able to determine the intangible boundary between taxation engineering (legal taxation optimization opportunities) and tax planning (morally reprehensible tax evasion). Through case law, the taxation judge takes part in restoring tax justice, the confidence in the tax administration, the preservation of rights and guarantees for the taxpayer, and the desire to promote and encourage tax residency as the basis of a social contract.
Modeling of global solar radiation in Algeria based on geographical and all climatic parameters
Authors: SABAH Fetah , SALMİ Mohamed
Published: November 2021

The design of photovoltaic or solar systems and estimating their performance require knowledge of the intensity of solar radiation. The measurement of this parameter for some sites in Algeria is unfortunately not obvious. However, researchers are moving towards the modeling, estimation and prediction. To model the global solar radiation in Algeria, we must take into account the geographical and climatic parameters such as sunshine duration, relative humidity, temperature, latitude site, etc... In this study, the modeling of daily global solar radiation on a horizontal plane according to the parameters mentioned above is based on the statistical linear regression technique. The daily data used in the development and validation of models are extracted from the database of O. N. M (National Office of Meteorology, Dar el Beida. Algeria) for 2001-2005. We test the proposed models on two sites such as Djelfa and Ain-Bessam. For each site, validity and performance of the model will be studied based on the number of parameters introduced in the analytical expressions and results are discussed in terms of statistical errors as: R, MBE and RMSE between the measured global solar radiation and global solar radiation estimated. It was found that air temperature and relative humidity are indeed important climatic parameters for the prediction of solar radiation.

Resistência à abrasão e resistência à compressão de materiais para modelos e troquéis: influência de sua imersão prévia em óleo.
Authors: Süffert Léo Werner , Pessoa Ennio
Published: November 2021

Gypsum products are generally considered, by the majority of investigators, to possess the greatest amount of desirable properties, when used as model or die materials. The property, however, in which they are less efficient is the one related to abrasion resistance. The authors describe a new method to measure the abrasion resistance of gypsum products and recomend their immersion in innert mineral oil, prior to their use, in order to increase this proferty. Studdying, simultaneously, the compressive strenght of the same materials, the authors verify that, even though some of the gypsum products have their compressive strengts diminished due to a previous immersion in oll, the d'fferences, expressed in kg/cm², have no clinical significance, considering their use as model or die materials, which are much more subjected to abrasion or cutting actions in the dental laboratory. The results were statistically analysed.

Measuring enterprise resource planning (ERP) systems success from a managerial accounting perspective
Authors: Ulrich Patrick , Güler Hasan Andac
Published: November 2021

A major objective of management accounting is to support managers in decision-making by providing decision-relevant interdepartmental information. Hence, enterprise resource planning (ERP) systems are important for the application of management accounting techniques as they streamline the necessary information. Besides the fact that ERP systems are important, there was little research conducted which is directly concerned with concrete benefits that arise with the use of ERP systems within management accounting. This study with 94 participants contributes to this research field by examining benefits that arise with the use of ERP systems within management accounting and the characteristics that are crucial for achieving those benefits. As there was a recent wave of new ERP systems (i.e., SAP S/4HANA®), the results were clustered into organizations that are using traditional and modern ERP system where appropriate (i.e., response time). The outcomes indicate that using ERP systems within management accounting offers benefits that are positively interrelated with the extent and the satisfaction of using this information to make decisions. As a higher extent of using this information and a higher degree of satisfaction with this information is positively interrelated with organizational performance, we show that using ERP systems within management accounting helps improve organizational performance

Published: November 2021

Neural Tube Defects (NTDs) are congenital malformations resulting from
abnormal embryonic development of the brain, spine, or spinal column.
The genetic etiology of human NTDs remains poorly understood despite
intensive investigation. CIC, homolog of the Capicua transcription
repressor, has been reported to interact with ataxin-1 (ATXN1) and
participate in the pathogenesis of spinocerebellar ataxia type 1. Our
previous study demonstrated that CIC loss of function (LoF) variants
contributed to cerebral folate deficiency by downregulating folate
receptor 1 (FOLR1) expression. Given the importance of folate transport
in neural tube formation, we hypothesized that CIC variants could
contribute to increased risk for NTDs by depressing embryonic folate
concentrations. In this study, we examined CIC variants from whole
genome sequencing (WGS) data of 140 isolated spina bifida cases and
identified 8 missense variants of CIC gene. We tested the pathogenicity
of the observed variants through multiple in vitro experiments. We
determined that CIC variants decreased FOLR1 protein level and planar
cell polarity (PCP) pathway signaling in a human cell line (HeLa). In a
murine cell line (NIH3T3), CIC loss of function variants down regulated
PCP signaling. Taken together, this study provides evidence supporting
CIC as a risk gene for human NTD.

Published: November 2021

Background: Catheter ablation is an effective treatment for ventricular
tachycardia (VT), albeit the decision to undergo this procedure is often
influenced by underlying comorbidities. The present study aims at
evaluating the effects of chronic kidney disease (CKD) on clinical
outcomes of VT ablation. Methods: We identified 7,212 patients who
presented between 2016-2018 and underwent catheter ablation for VT.
Their clinical data were retrospectively accrued from the national
readmission database (NRD) using the corresponding diagnosis codes. We
compared clinical outcomes between patients with chronic kidney disease
(CKD-group) and patients without. Odds ratios (OR) for the primary and
secondary outcomes were calculated, and multivariable regression
analysis was utilized to adjust for confounding variables. Results:
Compared with patients without CKD, patients in CKD-group were older
(mean age 67.9 vs. 60.5 years, P <0.01), had a longer mean
length of stay (8.73 vs. 5.69 days, P <0.01), and higher
in-hospital mortality (OR 2.24, 95% confidence interval (CI)
(1.29-3.88), P<0.01). CKD-group patients had increased risk of
developing acute kidney injury (10% vs. 8.6%, P<0.01) and
30-day readmission rate due to VT (OR 1.77, 95% CI (1.17-2.69),
P<0.01). Conclusion: In patients with CKD, VT ablation is
associated with worse clinical outcomes in-hospital mortality and 30-day
readmission rate. This significantly influences the decision-making
prior to performing this procedure.
High resolution species detection: accurate long read eDNA metabarcoding of North Sea fish using Oxford Nanopore sequencing

Published: November 2021

To monitor the effect of nature restoration projects in North Sea
ecosystems, accurate and intensive biodiversity assessments are vital.
DNA based techniques and especially environmental DNA (eDNA)
metabarcoding from seawater is becoming a powerful monitoring tool.
However, current approaches are based on genetic target regions of
<500 nucleotides, which offer limited taxonomic resolution.
This study aims to develop and validate a long read nanopore sequencing
method for eDNA that enables improved identification of fish species. We
designed a universal primer pair targeting a 2kb region covering the 12S
and 16S rRNA genes of fish mitochondria. eDNA was amplified and
sequenced using the Oxford Nanopore MiniON. Sequence data was processed
using the new pipeline Decona, and accurate consensus identities of
above 99.9% were retrieved. The primer set efficiency was tested with
eDNA from a 3.000.000 L zoo aquarium with 31 species of bony fish and
elasmobranchs. Over 55% of the species present were identified on
species level and over 75% on genus level. Next, our long read eDNA
metabarcoding approach was applied to North Sea eDNA field samples
collected at ship wreck sites, the Gemini Offshore Wind Farm, the Borkum
Reef Grounds and a bare sand bottom. Here, location specific fish and
vertebrate communities were obtained. Incomplete reference databases
still form a major bottleneck in further developing high resolution long
read metabarcoding. Yet, the method has great potential for rapid and
accurate fish species monitoring in marine field studies.

Published: November 2021

The pastoralists are economically depend upon livestock for their income which include their herds of livestock and the bi products produced and sold. The nomads keep moving in search of food and forage so they do not completely destroy the natural resource of a particular area. During their journey of searching water sometimes make them closer to the agriculture land near towns where they used to earn through off farm activities which include the income earned through their unskilled labour activities. The multinomial probit regression employed in this study for analysis revealed that many pastoralists adopt the income diversification strategies which are the coping strategies for other than livestock income to reduce the risks attached with livestock income. The role of Govt. and NGOs for improvement in infrastructure is envisaged to find the enhancement of livestock sector in the area is explored in this study. The study is unique in providing perspective on providing access to different facilities and the role of government in improving living of population.

A INTRODUÇÃO E DISTRIBUIÇÃO DO TUCUNARÉ-AZUL E DO TAMBAQUI NO PANTANAL CORUMBAENSE
Authors: Cordova Junior Renner Fernando da Silva
Published: November 2021

O Pantanal possui características únicas, porém similares à Bacia Amazônica, principalmente no que tange os ciclos de cheias em ambas as regiões. Tais semelhanças permitiram que espécies de peixes introduzidas como o tucunaré-azul (Cichla piquiti) e o tambaqui (Colossoma macropomum) se desenvolvessem na região pantaneira após escape de tanques, escavados na década de 1980. Neste sentido, foi realizada a averiguação da ocorrência de tais espécies nos principais pontos de pesca, no rio Paraguai, partindo da cidade de Corumbá, na planície pantaneira. Nos pontos analisados, foi feita pesca de exemplares com a utilização de apetrechos de pesca permitidos pela legislação vigente para a pesca amadora, considerando o esforço de pesca de oito horas por dia de campanha amostral, totalizando sete campanhas e 56 horas de esforço amostral entre 2018 e 2019. Os resultados apontam que o tucunaré já se encontra amplamente espalhado na planície pantaneira, já o tambaqui ainda se mantém restrito à algumas baías. Sendo assim, é necessário que haja um monitoramento das espécies e estudos comportamentais desses espécimes para compreender e mitigar os impactos da sua introdução em tão importante planície.

O consumo de água contaminada gera sérios problemas de saúde em populações humanas e também na produção animal das regiões rurais. Paralelamente, a ingestão de microrganismos resistentes a antibióticos, ou seja, que sobrevivem ao tratamento com determinados antibióticos, deve ser cuidadosamente considerada sob o ponto de vista de saúde única. Nesse sentido, os objetivos do presente trabalho foram: 1) avaliar a qualidade microbiológica da água e sua conformidade para consumo animal em propriedades rurais de Santa Catarina, e 2) avaliar a resistência antimicrobiana de isolados de Escherichia coli. A quantidade de coliformes fecais foi determinada pela técnica de tubos múltiplos, e utilizada para definir a classe de qualidade e uso da água, com base em resoluções federais. A resistência a antimicrobianos foi estudada por antibiograma, com o método de difusão por disco. Cinco das 15 propriedades apresentaram valores de coliformes fecais acima do limite permitido para consumo animal. Porém, a resistência antimicrobiana foi detectada em resposta a maioria dos antibióticos testados: ampicilina (19,7%), tetracicilina (17,85%) e ampicilina+sulbactam (1,78%). Nenhum isolado de E. coli foi resistente a ciprofloxacino. Esses dados obtidos alertam para a importância do tratamento de água, bem como da preservação de recursos hídricos em geral, para minimizar efeitos negativos da ocorrência de doenças em animais e evolução da multirresistência.
