Response of simultaneous nitrification-denitrification to DO increments in continuously aerated biofilm reactors for aquaculture wastewater treatment
Authors: Zhang Shiyang , Chen Jing , Yuan Julin , Wang Guangjun
Published: July 2021

Intensive aquaculture usually produces large volumes of nutrient-rich wastewater, which is essential to treat to avoid eutrophication. This study aimed to evaluate the performance of five continuously aerated biofilm reactors treating simulated high-strength aquaculture wastewater under different dissolved oxygen (DO) levels, and the effects of DO increments on simultaneous nitrification-denitrification (SND). Continuous aeration was beneficial to complete nitrification. Total inorganic nitrogen (TIN), principally ammonium, was mainly removed by SND. The SND rate response to different DO levels was fitted well by the power function of y = 54.81 + 371.58/(1 − 0.16*x)^(−1/0.24) (R2 = 0.897, P = 0.000). When the TIN was removed completely, the optimal SND rate was defined and corresponded to a value of 121.8%. Accordingly, the optimal DO concentration was calculated as 2.10 mg/L, close to the actual level of 1.83 mg/L, at which the highest proportional removals of total nitrogen (58.0%) and TIN (57.3%) were obtained. Phosphorus was also removed by denitrifying polyphosphate-accumulating organisms.

Radon (222Rn), radium (226Ra) and uranium (238U) concentration in the samples of marshes' water have been measured. The samples were collected from various places at the marshes, in Dhi-Qar governorate. The method that used in the present study is the can technique by Solid State Nuclear Track Detectors (SSNTDs) with CR-39 detectors. Also, it was determined the average internal effective dose risk (AED), with lifetime cancer risk due to ingestion of 222Rn and 226Ra in drinking water. The average values of 222Rn, 226Ra and uranium 238U concentration in water samples were found to be 288.02 ± 31.21 Bq/m3, 0.45 ± 0.04 Bq/L, and 0.60 ± 0.06 ppm, respectively. The average values of AED (in mSv/y unit) caused by ingestion of 222Rn and 226Ra in the samples of the study were found to be 0.019 ± 0.002 and, 0.093 ± 0.01, respectively. The average values of total AED and lifetime cancer risk values were calculated to be 0.11 ± 0.01 mSv/y and (4.34 ± 0.47) × 10−4, respectively. The average concentration values of 222Rn and 226Ra were found to be within the global average limitations (0.4 Bq/L), and (1 Bq/L) that are recommended by World Health Organization (WHO) in 1993 and 2011, while the average of 238U concentrations were higher than that of the global average limitation (0.566 ppm) that was recommended by Environmental Protection Agency (EPA). When some results of AED due to 222Rn and 226Ra concentrations, in the samples under study, were compared with the worldwide median value it was found that the lifetime cancer risk in all samples of the present study were higher than the safety limit for the healthy drinking water. Therefore, consuming the water of marshes in the Dhi-Qar Governorate, Iraq, for cooking and drinking (which is contaminated with alpha emitters like 222Rn, 226Ra, and 238U) may lead to a considerable variation in the internal effective dose.

Published: July 2021

Quinones and humus are ubiquitous in the biosphere and play an important role in the anaerobic biodegradation and biotransformation of organic acids, poisonous compounds as well as inorganic compounds. The impact of humic model compound, anthraquinone-2, 6-disulfonate (AQDS) on anaerobic phenol and p-cresol degradation were studied. Four methanogenic AQDS-free phenol and p-cresol enrichments and two phenol-AQDS enrichments were obtained using two sludges with potential biodegradability of phenol and cresol isomers as inoculum. 16S rRNA gene-cloning analysis combined with fluorescence in situ hybridization revealed that syntrophic aromatic compound degrading bacterium Syntrophorhabdus aromaticivorans was dominant in four AQDS-free enrichments, whereas phenol degrading Cryptanaerobacter phenolicus was dominant in two phenol-AQDS enrichments. Neither co-culture of S. aromaticivorans with Methanospirillum hungatei nor two phenol-AQDS enrichments could metabolize phenol using AQDS as the terminal electron acceptor. Further degradation experiments suggested that C. phenolicus related microbes in two phenol-AQDS enrichments were responsible for the conversion of phenol to benzoate, and benzoate was further degraded by benzoate degraders of Syntrophus aciditrophicus or Sporotomaculum syntrophicum to acetate.

Published: July 2021

This article presents a numerical model of pressure fields during filtration of reservoir fluid, which accounts for the effect of the well. The mathematical formulation of the problem under consideration includes the equation of piezoconductivity in a cylindrical coordinate system and differs in a non-classical boundary condition obtained from the ratio of the balance of mass and momentum. The authors compare the numerical calculations and the analytical solution constructed in the Laplace — Carson image space. Den Iseger’s numerical algorithm is used to convert it to the original space. As a result of the comparison, the area of applicability of the computational experiment was determined. It is shown that in the case of a limited reservoir, the exact solution of the problem coincides with a numerical experiment over the entire domain of definition. In the case of an infinite reservoir, the numerical model is applicable only in the region of small times, the dimensions of which are determined by the values of the right boundary and the radial coordinate.

Published: July 2021

Background: Non-alcoholic steatohepatitis (NASH) is an expanding cause of chronic liver disease worldwide, including Indonesia, with higher risk progression to cirrhosis and hepatocellular carcinoma. Preclinical experiments using several mice models have been conducted to clarify its complex pathogenesis. This study was designed to investigate whether BALB/c mice on a choline-deficient high-fat diet can be used as a model for NASH. Materials and Methods: BALB/c male mice were fed choline-deficient L-amino acid-defined high-fat diet (CDAHFD) or a standard diet for six weeks. The body and liver weights, liver histology, and plasma biochemistry were analyzed. The relative expression levels of tumor necrosis factor (TNF)α, transforming growth factor (TGF)β1, collagen-1α1 (COL1α1), glutathione peroxidase 1 (GPx1), and uncoupling protein 2 (UCP2) genes in the livers were analyzed using a two-step real time-polymerase chain reaction. Liver fatty acids composition was analyzed using gas chromatography with flame ionization detector (GC-FID). Results: CDAHFD induced steatohepatitis in BALB/c mice with increased plasma levels of alanine aminotransferase. The liver of CDAHFD-fed BALB/c mice showed upregulated relative expression levels of TNFα, TGFβ1, COL1α1, GPx1, and UCP2 genes. The liver fatty acid analysis showed a significant accumulation of saturated fatty acids (SFAs) and an increased ratio of n-6/n-3 polyunsaturated fatty acids (PUFAs) in the livers of CDAHFD-fed BALB/c mice. Conclusion: This study suggests that CDAHFD can induce steatohepatitis in BALB/c mice and therefore may be used as NASH mice model.Keywords: steatohepatitis, fatty liver, choline-deficient high fat diet, BALB/c

Authors: Chen Jinlan , Meng Enqing , Lin Yexiang , Shen Yujie , Hu Chengyu , Zhou Gang , Yuan Chengfu
Published: July 2021

Background:

As it is known, long non-coding RNA (lncRNA) affects tumor progression, which has
caused a great upsurge in recent years. It can also affect the growth, migration, and invasion of tumors. The abnormal
expression of lncRNA is associated with malignant tumors. In addition, it has been proved that lncRNA
is a key targeted gene for the treatment of some diseases. PART1, a member of lncRNA, has been reported as a
regulator in the process of tumor occurrence and development. This study aims to reveal the biological functions,
specific mechanisms, and clinical significance of PART1 in various tumor cells.

Methods:

Through the careful search of PUBMED, the mechanisms of the effect of PART1 on tumorigenesis
and development are summarized.

Results:

On the one hand, the up-regulated expression of PART1 plays a tumor-promoting role in tumors, including
lung cancer, prostate cancer, bladder cancer, and so on. On the other hand, PART1 is down-regulated in
gastric cancer, glioma, and other tumors to play a tumor inhibitory role. In addition, PART1 regulates tumor
growth mainly by targeting microRNA, such as miR-635, directly regulating the expression of proteins, such as
FUS/EZH2, affecting signal pathways, such as Toll-like receptor pathway, or regulating immune cells.

Conclusion:

PART1 is closely related to tumors by regulating a variety of molecular mechanisms. In addition,
PART1 can be used as a clinical marker for the early diagnosis of tumors and plays an important role in tumortargeted
therapy.

Published: July 2021

Background:

Raphanus sativus is traditionally used as an anti-inflammatory agent.

Objectives:

The current study was designed to explore the in vivo anti-inflammatory and antiangiogenic
properties of Raphanus sativus seeds oil.

Methods:

Cold press method was used for the extraction of oil (RsSO) and was characterised by using
GC-MS techniques. Three in vitro antioxidant assays (DPPH, ABTS and FRAP) were performed to explore
the antioxidant potential of RsSO. Disc diffusion methods were used to study in vitro antimicrobial
properties. In vivo anti-inflammatory properties were studied in both acute and chronic inflammation
models. In ovo chicken chorioallantoic membrane assay was performed to study antiangiogenic effects.
Molecular mechanisms were identified using TNF-α ELISA kit and docking tools.

Results:

GC-MS analysis of RsSO revealed the presence of hexadecanoic and octadecanoic acid. Findings
of DPPH, ABTS, and FRAP models indicated relatively moderate radical scavenging properties of
RsSO. Oil showed antimicrobial activity against a variety of bacterial and fungal strains tested. Data of
inflammation models showed significant (p < 0.05) anti-inflammatory effects of RsSO in both acute and
chronic models. 500 mg/kg RsSO halted inflammation development significantly better (p < 0.05) as
compared with lower doses. Histopathological evaluations of paws showed minimal infiltration of inflammatory
cells in RsSO-treated animals. Findings of TNF-α ELSIA and docking studies showed that
RsSO has the potential to down-regulate the expression of TNF-α, iNOS, ROS, and NF-κB respectively.
Moreover, RsSO showed in vivo antiangiogenic effects.

Conclusion:

Data of the current study highlight that Raphanus sativus seeds oil has anti-inflammatory,
and antiangiogenic properties and can be used as an adjunct to standard NSAIDs therapy which may
reduce the dose and related side effects.

Authors: Swain Shasank S. , Hussain Tahziba , Pati Sanghamitra
Published: July 2021

Background:

Today, the occurrence and recurrence of multidrug-resistant tuberculosis
strains and comorbidities are the main reasons for long-term morbidity and mortality from tuberculosis
from the nasty acid-fast pathogen Mycobacterium tuberculosis. Therefore, discovering and developing
well-tolerated and non-toxic antituberculosis regimens are directly needed to defend the variants
strains of M. tuberculosis and, alternatively, support WHO’s ‘END-TB’ campaign.

Objective:

Alternatively, phytochemicals from various common and medicinal plants have always
been vital therapeutic agents since the primitive era. Thus, proper scientific documentation as diversity,
potency, structure, drug-chemistry and overall critical analysis are essential tools to accelerate the
phytochemical-based anti-TB drug development.

Methods:

In the present review, we have used some specific keywords such as ‘antituberculosis phytochemicals’,
; antituberculosis phytochemicals from plant source; ‘natural products against tuberculosis’
in Google, PubMed, ScienceDirect sites to get more appropriate research publications.
Further, based on lower minimum inhibitory concentration within fifty μ g/mL, a total of twohundred-
twenty-one bioactive anti-TB phytochemicals were selected for critical drug-chemistry and
structural activity relationship analyses to select most potential ‘lead candidate’ for anti-TB drug development.

Results:

Based on lower concentration, abietane, ethyl-p-methoxycinnamate, ergosterol peroxide,
mono-O-methyl curcumin isoxazole, 7-methyljuglone, 12-demethylmulticaulin, 12-methyl-5-
dehydroacetylhorminone, tryptanthrin, etc. are some of the potential anti-TB phytochemicals. Interestingly,
existing and clinical drug pipelines for TB contain several active phytochemical pharmacophores
illustrated from the structural analysis.

Conclusion:

Therefore, updated experimental documentation and structural-cum-critical drugchemistry
analysis on isolated antituberculosis phytochemicals at the primary level are more beneficial
for drug developers, R&D centres, and pharmaceutical companies to accelerate anti-TB drug
development using phytochemicals.

Published: July 2021

The investigation of a Dye-Sensitized Solar Cell (DSSC) as an alternative approach to the
conventional photovoltaic cell (silicon-based) is attracting remarkable attention recently. This stems
from the excellent optical properties of graphene, such as impressive transparency, conductance in
near-infrared and visible light spectrums, along with its thermochemical stability, as reported in the
literature. However, the main limitation of graphene production is the lack of suitable methods for its
industrial-scale synthesis. Consequently, the research on industrial applications of graphene development
and understanding of how to pragmatize existing theoretical approaches are still ongoing in
the related research domain. This is exemplified in single, few, and adhesive layer mechanical cleavage
graphene methods, which are not yet practicable, as these methods will restrict the chance for
scaling up. These limitations and inadequate reviews on graphene development impelled the authors
to compile the advances in graphene synthesis, properties, recent applications, and future directions.
The mechanical exfoliation synthesis technique delivers quality graphene films sized from 5 to 10
μm. Graphene-TiO2 hybridization was also found to possess efficiency acclivity as high as 39%. This
review provides significant implications for a better understanding of graphene performance indicators
and insight for future research in photovoltaic or optical modulation devices.

Published: July 2021

Background:

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia
in which the blood sugar levels are increased. Nepalese medicinal plants are being used traditionally
since long back in the treatment of diabetes. These plants have provided a broad research
area in modern medicine development due to their potency to inhibit digestive enzymes. The isolated
compounds and crude extract of these plants exhibited the property of inhibiting the digestive enzymes
(α-amylase and α-glucosidase).

Objective:

This review's primary purpose is to explore the inhibitory activity of Nepal's medicinal
plants against the digestive enzymes (α-amylase and α-glucosidase) as a practical approach to control
type-2 diabetes mellitus (T2DM). Twenty Nepalese medicinal plants belonging to 19 families
and compounds isolated from them possessing potent inhibitory activity against digestive enzymes
and are responsible for managing postprandial hyperglycemia are reviewed under this article.

Methods:

The scientific evidence of the tabulated medicinal plants' function in managing postprandial
hyperglycemia through inhibition of digestive enzymes (α-amylase and α-glucosidase) was
carefully investigated online. As a result, searches in PubMed, Research Gate, and Google Scholar
were conducted. All of the data from the various sources have been organized in a structured manner.

Result and Conclusion:

From the database available, twenty plants with their crude extract and
some isolated compounds and their IC50 values are tabulated. Thus, these compounds could be vital
components in drug design with fewer side effects and could be a replaceable agent to conquer diabetes
threats.

The flipped learning approach has been accepted by numerous studies as an approach in implementing technological based classroom environments. This article aims to identify the required constructs in developing an instrument for flipped learning in an ESL environment. This study uses the Fuzzy Delphi method to collect and analyze the viewpoints of 18 experts from relevant fields. An online questionnaire was developed to gather the experts’ agreement towards seven constructs namely flexible environments, shift in learning culture, intentional content, progressive networking activities, professional educators, engaging & effective learning experiences, and diversified seamless learning platforms and 68 items gathered from the literature. The FDM (Fuzzy Delphi Method) analysis rejected seven of the items; finalizing the instrument with seven constructs and 61 items. The instrument is beneficial to teachers and learners of ESL and developers of technology-based learning methods. The implication of the study is the provision of the constructs to help guide and implement the flipped learning approach in educational contexts. Furthermore, these constructs can be used to the basis for further investigations that leads to the development of frameworks or models for the flipped learning approach. Future works on the topic may look at a bigger sample for stronger results. Furthermore, the instrument developed can be used on the student population and in other contexts as well.

Authors: Purnama Chandra Yudistira , Ernawati Linda
Published: July 2021

The assessment tool for a career currently being developed requires special treatment from a psychologist/psychometrist. The measurements are conducted when students are confused about career options. However, for students who have decided, it is uncommon for them to seek professional help. Psychological tools that focus on capturing information about students’ maturity in relation to their ability to make career decisions can help them choose a major that’s suitable for their career. This study concern on adapting the career decision-making self efficacy (CDMSE) that can predict one’s confidence in his/her ability to make career choices. The adaptation of this instrument went through several stages such as translation, back translation, testing the reliability, and testing the validity evidence of content and internal structure using confirmatory factor analysis (CFA). This study used a sample of 539 high school students in Bandung and Cimahi. The construct reliability (CR) of the instrument was α=0.929. The evidence for internal structure using CFA showed that the CDMSE scale has an acceptable goodness of fit index. The standardized loading factor item in the range 0.710-0.998. It can be concluded that the Bahasa Indonesia version of the CDMSE scale has good psychometric properties and can be used for research or assessment to measure a person’s degree of confidence about his/her ability to make career choices.

Professzionális magyar jégkorongozók személyiségének, megküzdési stratégiáinak és megélt stressz-szintjének vizsgálata
Authors: Tóth Renátó , Szabó Kinga
Published: July 2021

A tanulmány fő célja feltárni bizonyos pszichológiai jelenségek (személyiség, megküzdési stratégiák, stressz) szerepét a hivatásos magyar profi jégkorongozók körében. A kutatás során az online kérdőíves eszközcsomagot 65 hivatásos magyar jégkorongozó töltötte ki. Az eredmények alapján megállapítható, hogy bizonyos személyiségjegyek (neuroticitás, extraverzió, lelkiismeretesség) központi szerepet töltenek be a sportolók stressz-szintjére, valamint regenerációjára nézve. Továbbá bebizonyosodott, hogy különbség van különböző stressz-szinttel rendelkező jégkorongozók megküzdési képességei között. Összességében ezeknek az adatoknak a tükrében sikerült olyan következtetéséket levonni, amelyek hozzájárulhatnak a sportolók eredményesebb és sikeresebb teljesítményéhez. Továbbá számos továbbfejlesztési lehetőséget tesz lehetővé a tanulmány, mint például egyéb sportág képviselőinek a bevonását a kutatásba és az eredmények összehasonlítását.
Kritikus helyzetek a labdajátékokban és a „láthatatlan” mentális tényezők - Citius, altius, fortius
Authors: Magas István
Published: July 2021

Lehet-e a sportolók mentális képességeit fejleszteni a labdajátékokban? Mennyire „taníthatók” kritikus helyzetek esetére a játékosok döntéshozatali képességei? Kritikus helyzetekben a reakciók (cselekvés) kimenetelének mik a legmegbízhatóbb előrejelzései? Ezekre a kérdésekre keresi a választ az alábbi írás, amelyben három labdajátékból (labdarúgás, vízilabda és tenisz) merítve kínál példákat a kritikus döntési – gól vagy pontszerzési – helyzetekben. A legfontosabb következtetés, hogy noha a kritikus helyzetekben történő cselekvés mentális (agyi) folyamatok ugyan nem azonosíthatók megbízható és megismételhető, mérhető módon, mégis léteznek, és relatíve jó indikátorai a leginkább várható kimenetnek. Ezek pedig a korábbi, hasonló helyzetben készült statisztikák. Megállapításra került, hogy az ideálisnak tekintett mentális állapotok „előhívása” az agyból nem automatikus, de a korábbi pozitív tapasztalatok – kiemelkedő játékos esetében – jól mozgósíthatók. Sőt, éppen ez a mentális mozgósítási képesség emelheti ki a klasszis játékosokat a mezőnyből, mert motorikus végrehajtási képességgel nagyon sok játékos rendelkezik.
Hospital Investment Decisions in Healthcare 4.0 Technologies: Scoping Review and Framework for Exploring Challenges, Trends, and Research Directions
Authors: Vassolo Roberto Santiago , Mac Cawley Alejandro Francisco , Tortorella Guilherme Luz , Fogliatto Flavio Sanson , Tlapa Diego , Narayanamurthy Gopalakrishnan
Published: July 2021

Background

Alternative approaches to analyzing and evaluating health care investments in state-of-the-art technologies are being increasingly discussed in the literature, especially with the advent of Healthcare 4.0 (H4.0) technologies or eHealth. Such investments generally involve computer hardware and software that deal with the storage, retrieval, sharing, and use of health care information, data, and knowledge for communication and decision-making. Besides, the use of these technologies significantly increases when addressed in bundles. However, a structured and holistic approach to analyzing investments in H4.0 technologies is not available in the literature.

Objective

This study aims to analyze previous research related to the evaluation of H4.0 technologies in hospitals and characterize the most common investment approaches used. We propose a framework that organizes the research associated with hospitals’ H4.0 technology investment decisions and suggest five main research directions on the topic.

Methods

To achieve our goal, we followed the standard procedure for scoping reviews. We performed a search in the Crossref, PubMed, Scopus, and Web of Science databases with the keywords investment, health, industry 4.0, investment, health technology assessment, healthcare 4.0, and smart in the title, abstract, and keywords of research papers. We retrieved 5701 publications from all the databases. After removing papers published before 2011 as well as duplicates and performing further screening, we were left with 244 articles, from which 33 were selected after in-depth analysis to compose the final publication portfolio.

Results

Our findings show the multidisciplinary nature of the research related to evaluating hospital investments in H4.0 technologies. We found that the most common investment approaches focused on cost analysis, single technology, and single decision-maker involvement, which dominate bundle analysis, H4.0 technology value considerations, and multiple decision-maker involvement.

Conclusions

Some of our findings were unexpected, given the interrelated nature of H4.0 technologies and their multidimensional impact. Owing to the absence of a more holistic approach to H4.0 technology investment decisions, we identified five promising research directions for the topic: development of economic valuation methodologies tailored for H4.0 technologies; accounting for technology interrelations in the form of bundles; accounting for uncertainties in the process of evaluating such technologies; integration of administrative, medical, and patient perspectives into the evaluation process; and balancing and handling complexity in the decision-making process.
National-Level Disparities in Internet Access Among Low-Income and Black and Hispanic Youth: Current Population Survey
Authors: Dolcini M Margaret , Canchola Jesse A , Catania Joseph A , Song Mayeda Marissa M , Dietz Erin L , Cotto-Negrón Coral , Narayanan Vasudha
Published: July 2021

Background

Internet access is increasingly critical for adolescents with regard to obtaining health information and resources, participating in web-based health promotion, and communicating with health practitioners. However, past work demonstrates that access is not uniform among youth in the United States, with lower access found among groups with higher health-related needs. Population-level data yield important insights about access and internet use in the United States.

Objective

The aim of this study is to examine internet access and mode of access by social class and race and ethnicity among youth (aged 14-17 years) in the United States.

Methods

Using the Current Population Survey, we examined internet access, cell phone or smartphone access, and modes of connecting to the internet for adolescents in 2015 (unweighted N=6950; expanded weights N=17,103,547) and 2017 (unweighted N=6761; expanded weights N=17,379,728).

Results

Internet access increased from 2015 to 2017, but socioeconomic status (SES) and racial and ethnic disparities remained. In 2017, the greatest disparities were found for youth in low-income households (no home access=23%) and for Black youth (no home access=18%) and Hispanic youth (no home access=14%). Low-income Black and Hispanic youth were the most likely to lack home internet access (no home access, low SES Black youth=29%; low SES Hispanic youth=21%). The mode of access (eg, from home and smartphone) and smartphone-only analyses also revealed disparities.

Conclusions

Without internet access, web-based dissemination of information, health promotion, and health care will not reach a significant segment of youth. Currently, SES and racial and ethnic disparities in access prolong health inequalities. Moreover, the economic impact of COVID-19 on Black, Hispanic, and low-income communities may lead to losses in internet access for youth that will further exacerbate disparities.
