Published: February 2021

This paper aims to analyze the link between the disclosure of zakat information and the performance of Islamic financial institutions in Yemen. Panel data of three Islamic banks working in Yemen were used. The study used a 16-item disclosure index to measure zakat disclosure information, and the financial performance of banks was calculated using two proxies, such as return on assets (ROA) and return on equity (ROE). Based on secondary data, this study used correlation matrix, descriptive analysis and regression analysis. ROA results revealed that zakat data and the age of a bank significantly affected financial results calculated by ROA, while the size of Islamic banks had an insignificant influence of banking performance. Zakat information and the size of Islamic banks have a positive effect on bank performance, while the age of the bank negatively influences the performance of banks. The results concerning ROE indicated that zakat data and the age of a bank have a strong and significant influence on the performance of banks, determined by ROA, while the size of a bank has a negative and insignificant effect on the performance of banks, determined by ROE.

Published: February 2021

Fluorosis is the most widespread and serious endemic disease in the abandoned Yellow River flooding delta of East China. One of the important causes of fluorosis is drinking high-fluorine groundwater. In this study, 313 groundwater samples were collected in the central part of the flooding delta to address the chemistry of high-fluoride groundwater, and 33 core samples were collected from one borehole of 150 m depth to analyse the vertical distribution characteristics of total fluorine and water-soluble fluorine. The fluorine concentration in groundwater ranges from 0.2 to 6.7 mg/L, and 72.8% of the samples have fluorine above the China maximum permissible limit of 1.0 mg/L for drinking water. These 313 samples can be divided into nine hydrochemical subtypes, and over 77% of the samples belong to the bicarbonate types. High-fluorine groundwater (over 3.0 mg/L) is generally alkaline water with high HCO3− and low Ca2+. The concentration of water-soluble fluorine decreases gradually with the increase of formation depth, and that in vertical sediment is negatively correlated with Ca2+ and Cl−, but positively correlated with HCO3−. According to the calculation by PHREEQC package, MgF+ and CaF+ are the dominant species controlling the endemic fluorosis of the study area.
Impact of microbial activity on the performance of planted and unplanted wetland at laboratory scale
Authors: Jamwal Priyanka , Shirin Shahana
Published: February 2021

Three horizontal subsurface flow constructed wetland prototypes were set up to identify and understand the role of microflora in nutrient removal under diverse operating conditions. Out of three setups, one setup served as a control (without plants), and the rest were planted with Typha domingensis. The setups were operated at two different hydraulic loading rates (5 cm/day and 16 cm/day) for two months each. Among 27 bacteria species isolated, 80% of nitrate-reducing bacteria were observed in control, and 50–77% of nitrate-reducing bacteria were observed in the plant setups. Presence of diverse denitrifying bacteria and soil organic carbon contributed to high Nitrate-N removal in the control at both HLRs. Similar Ammonium-N (29%) and Ortho-P removal (30%) efficiency was observed at both HLRs in the control setup. Processes such as chemical sorption and adsorption dominated the Ammonium-N and Ortho-P removal in the control setup. High average Ammonium-N removal efficiency of 89% and 52% was observed in plant setups at 5 cm/day and 16 cm/day HLR. At low HLR, Ammonium-N removal in plant setups was dominated by nutrient uptake. In the plant setups, 35% and 15% Ortho-P removal efficiency was observed at low HLR (5 cm/day) and high HLR (16 cm/day) respectively. Hydraulic Retention Time (HRT) limited the uptake of ortho-P, thereby allowing mineralised phosphorus to escape the system without being absorbed by the plants.

A Review on Anti-urease Potential of Coumarins
Authors: Asghar Humna , Asghar Hafsa , Asghar Tanzeela
Published: February 2021

Coumarins, a heterocyclic benzo-α-pyrones and naturally occurring ring structure that
possess significant pharmacological properties, have attracted the attention of researchers and
medicinal chemists to reveal the suitability of both natural and synthetic coumarins as drugs. Many
compounds have been synthesized utilizing the basic coumarin structure. The diverse synthetic
methods resulted in the synthesis of important coumarin derivatives that offer a wide range of biological
properties as antimicrobial, anticancer, anti-inflammatory, antioxidant, antidiabetic and antidepressant
that make them potential drug candidates. With a particular interest in ulcers, coumarins
have shown potential inhibition against urease enzyme. In recent years, scientists have emphasized
the anti-urease activity of coumarins due to their low toxicity. The aim of this review is to
compile data from recent research about anti-urease activities of coumarins and structure-activity
relationship studies of the coumarin ring structure. Investigation of different structural substitutions
in coumarin rings may help researchers to design new compounds with strong and effective anti-
urease abilities.

Published: February 2021

Introduction:

Copeptin is known to be associated with heart damage, while melatonin is
a regulatory hormone related to circadian rhythm and represents the levels of inflammation in the
body.

Methods and Patients:

The aim of the study was to measure in different surgeries the levels of
copeptin and melatonin at different times before and after surgery in 56 patients aged from 5 days
to 13.6 years. We measured copeptin in 50-microL serum and plasma samples from patients before
surgery, immediately after surgery, and 24 hours after surgery. The measured levels are aligned
with the published GC / MS data, and the sensitivity of the analysis is such that serum and plasma
levels can only be measured by rapid extraction. The measurement was made before surgery, immediately
after surgery, and 24 hours after surgery.

Results:

The multifactorial statistical analysis revealed a statistically significant difference between
the 24-hour postoperative copeptin values in group 1 (mild-moderate gravity surgery) and group 2
(severe surgery) of the severity of the surgery. Post-hoc tests with Tukey correction for age groups
in multiple comparisons of the multifactorial analysis revealed a statistically significant difference
(p <0.05) between 24-hour postoperative melatonin values in age groups 3 (3-6 years) and 5 (6-12
years old). The age group 3 showed significantly (p <0.05) lower 24 hours postoperative melatonin
values compared to the age group 5 (6-12 years). Again, these 3-6-year-olds were more likely to
have inflammation due to the severity of the surgery and the presence of inflammation after the
surgery.

Discussion:

In summary, copeptin is a reliable biomarker for assessing a patient's health both preoperatively
and postoperatively. Copeptin and melatonin are two independent agents and are not related
to each other, and more studies will be needed with more patients of the same age and with
the same underlying disease to assess their diagnostic value. Finally, melatonin could be considered
an indicator of inflammation on its own and based on pre-and post-surgery values to determine
a patient's health status and take appropriate actions.
Biogenic Amines (BAs) in Meat Products, Regulatory Policies, and Detection Methods
Authors: Shashank Abhinay , Gupta Arun Kumar , Singh Shubhendra , Ranjan Rajeev
Published: February 2021

Background:

Biogenic amines (BAs) can be defined as low molecular weight organic
nitrogen compounds formed by amino acid decarboxylation or by amination and transamination of
aldehydes and ketones. Histamine, tryptamine, tyramine, putrescine, phenylethylamine, and cadaverines
are some of the BAs reported in fermented foods which are synthesized by decarboxylation
of histidine, tryptophan, tyrosine, ornithine, phenylalanine, and lysine, respectively. In meat
and meat products, they are associated with spoilage. Excessive oral intake of these compounds
can result in several toxic effects on human health such as hypertension, cardiac palpitations,
headache, nausea, diarrhea, and flushing.

Objective:

Therefore, BAs must be controlled within the safety level to ensure the safety of fermented
meat products. The ratio and quantity of biogenic amines present can be used as an indicator
of the hygienic state of raw material as well as manufacturing practices.

Conclusion:

The detection and quantification of biogenic amines are commonly performed by
chromatographic approaches such as gas chromatography (GC), high-performance liquid chromatography
(HPLC), and capillary electrophoresis (CE). It can also be done by non-chromatographic
approaches like optical biosensors, disposable screen-printed electrode biosensors with enzymes,
transmission electron microscopy (TEM), and FTIR. There is enormous scope for making these
analytical techniques more rapid and simple. Thus, the purpose of this review is to deliver concise
information about the BAs, their significance, regulatory aspects, and the methods available to
quantify the BAs in meat and meat products.
Serratia, No Longer an Uncommon Opportunistic Pathogen – Case Series & Review of Literature
Authors: Gupta Varsha , Sharma Shiwani , Pal Kritika , Goyal Poonam , Agarwal Deepak , Chander Jagdish
Published: February 2021

Background:

Serratia spp. is a common enteric bacterium generally thought not to be
pathogenic in the gastrointestinal tract. Serratia marcescens is a member of the genus Serratia, which
is a part of the family Enterobacteriales. Of all Serratia species, S. marcescens is the most common
clinical isolate and the most important human pathogen.

Objective:

We discuss here four cases of Serratia marcescens which were reported in our laboratory at
the Department of Microbiology Government Medical College and Hospital Chandigarh within six
months of duration.

Method:

All the samples were processed and identified using standard microbiological techniques. The
isolates of Serratia marcescens were identified, depending upon their biochemical and morphological
characteristics, and further confirmed by MALDI-TOF-MS, PGIMER Chandigarh.

Result:

In one of the four cases, polymicrobial infection was observed, and among the cases, one patient
was diabetic and the rest three patients were immunocompetent. The importance of detection of
Serratia marcescens is related to the concern regarding its increased spread in hospital settings as
nosocomial infection.

Conclusion:

We need to identify and isolate this pathogen not thinking of it only as a contaminant and
opportunistic pathogen but as a pathogen which can lead to serious infections in hospital settings.
QSAR Analysis of Quinazolinyl-arylurea Derivatives as Potential Anti- Cancer Agents: GA-MLR Chemometric Approach
Authors: Srinivas Medidi , Neharika K Grace
Published: February 2021

Background:

Cancer is the most common malignancy in men and women globally. The
tyrosine kinases and serine/threonine kinases are essential to cell mediators for extra & intracellular
signal transduction processes and play a key role in cell proliferation, differentiation,
migration, metabolism, and programmed cell deaths. In this context, kinases are considered as a
potential drug target for cancer therapy.

Methods:

In the present study, a two-dimensional (2D) quantitative structure-activity relationship
(2D-QSAR) was performed to analyze anticancer activities of 28 quinazolinyl-arylurea (QZA)
derivatives based on the liver (BEL-7402), stomach (MGC-803), and colon (HCC-827) cancer cell
lines using multiple linear regression (MLR) analysis. It was accomplished using 2D-QSAR
analysis on the available IC50 data of 28 molecules based on theoretical molecular descriptors to
develop predictive models that correlate structural features of QZA derivatives to their anticancer
activities. A suitable set of molecular descriptors, such as constitutional, topological, geometrical,
electrostatic, and quantum-chemical descriptors were calculated to represent the structural features
of compounds. The genetic algorithm (GA) method was used to identify the important molecular
descriptors to build the QSAR models and used to predict the anti-cancer activities.

Results and Discussion:

The obtained 2D-QSAR models were vigorously validated using various
statistical metrics using leave-one-out (LOO) and external test set prediction approaches. The best
predictive models by MLR gave highly significant square of correlation coefficient (R2
train) values
of 0.799, 0.815, and 0.779 for the training set, and the correlation coefficients (R2
test) were obtained
0.885, 0.929, and 0.774 for the test set for the liver, stomach, and colon cancer cell lines. The
models also demonstrated good predictive power confirmed by the high value of cross-validated
correlation coefficient Q2 value of 0.663, 0.717, and 0.671 for three different cancer cell lines.
Importantly, the model's quality was judged as well based on mean absolute error (MAE) criteria,
and the results were consistent with proposed limits by Golbraikh and Tropsha.

Conclusion:

The QSAR results of the study indicated that the proposed models were robust and
free from chance correlation. This study indicated that maxHBint7, SpMax8_Bhm, and
ETA_Beta_ns_d have positively contributed descriptors for anti-cancer activity in the liver,
stomach, and colon cancer cell lines and a detailed mechanistic interpretation of each model
revealed important structural features that were responsible for favorable or unfavorable for anticancer
activity. The predictive ability of the proposed models was good and may be useful for
developing more potent quinazolinyl-arylurea compounds as anti-cancer agents.
Functionalized Photocatalytic Nanocoatings for Inactivating COVID-19 Virus Residing on Surfaces of Public and Healthcare Facilities

Published: February 2021

:

The current COVID-19 pandemic, caused by the Severe Acute Respiratory Syndrome
Coronavirus 2 (SARS-CoV-2) has affected the large population across the globe by serious respiratory
illness and death. Since the medicine for this new disease is yet to discover, the treatment options
against pandemic COVID-19 are very limited and unsatisfactory. Further, the hospitals,
wherethe COVID-19 patients are admitted for treatment, are the major source of the spread of this
virus, as it survives on the surfaces of inanimate objects for days. Therefore, hospitals have become
hotspots for SARS-CoV-2 infection. The non-availability of quality personal protective equipment
(PPE) and exposure to severe COVID patients have been major factors for the infection in millions
of healthcare workers. However, developing an effective medicine has remained challenging due to
its unpredictable mutation rate. Here, this article describes functionalized photocatalytic nanocoatings
to destroy the COVID-19 virus, which can be applied on the surface of inanimate objects,
such as paper, cloth, glass, wood, ceramic, metallic, and polymeric surfaces. With the supporting
experimental results, various possible ways of killing the virus and its relevant mechanism are discussed.
This article provides new insights for developing nano solutions to address this COVID-19
issue.

In the present study, two semi-empirical methods (geometric and polynomial) were proposed to calculate liquidus temperatures in ternary and quaternary systems using the data on the equilibria in the corresponding binary systems. Advantages, limitations, and peculiarities of application of the semi-empirical methods proposed were considered. The reliability of the results of calculating the liquidus temperature values in the Gd2O3-Y2O3-ZrO2 system was illustrated by comparison with the available data on the phase equilibria. The capacity to evaluate the eutectic line position in the temperature-composition coordinates was shown in multicomponent oxide systems. It was mentioned that the semi-empirical approaches proposed may find a further use to evaluate the liquidus temperature values in multicomponent systems with the aim of reducing the amount of experimental investigations of phase equilibria at high temperatures.

The possibility of modifying the nafion direct alcohol fuel cell proton-exchange membrane by monolayer graphene by hot pressing has been demonstrated. It is shown that this modification can reduce the permeability of the membrane on methanol while maintaining a high proton conductivity membrane, but with the long operation of the membrane without additional protection of the barrier layer formed in this way, it is detached. With a Nafion/graphene/Nafion membrane, the formed graphene layer is sufficiently protected to reduce the methanol crossover and increase the power of the single methanol fuel cell by 2 times.

В диапазоне ростовых температур (300-700)oС проведен анализ температурного поведения основных кинетических параметров, ответственных за скорости протекания на поверхности растущего слоя германия процессов пиролиза адсорбируемых молекул германа. Проведена оценка степени покрытия поверхности германия водородом и радикалами молекул германа. Установлена взаимосвязь характерной частоты пиролиза молекул гидридов со скоростью захвата молекул поверхностью и скоростью встраивания атомов Ge в растущий слой. Температурная зависимость скорости распада фрагментов молекул на поверхности германия обнаруживает немонотонное поведение, характер которого различен в разных температурных режимах и зависит от того, на каком этапе процесса сорбции происходит захват поверхностью водорода с адсорбируемой молекулы гидрида. Характеристики пиролиза германа сопоставляются с аналогичными характеристиками для пиролиза молекул силана. Обнаружено, что повышение концентрации рабочих газов в камере роста заметным образом сказывается на каталитических свойствах ростовой поверхности.

Participatory arts-based methods such as photovoice, drama and music have been increasingly used to engage young people who are exposed to psychosocial risks. These methods have the potential to empower young people and provide them with a safe and accessible environment to express and manage difficult feelings and experiences. These effects are, however, dependent on the way these methods are implemented and how potential ethical concerns are handled. Using the current literature on arts-based health research as a foundation, this paper examines ethical issues emerging from participatory arts methods with young people with traumatic experiences. A typology is presented covering ethical issues such as power, accessibility, communication, trust and ownership, across the domains of partnership working, project entry, participation and dissemination. Drawing on our extensive clinical and research experiences, existing research, and novel in-practice examples, we offer creative solutions to ethical dilemmas that might arise at different phases of research. Adequate anticipation and consideration of these issues, together with the involvement of young people, will help ensure that arts-based methodology is implemented in research and practice with young people in a fair, meaningful and empowering way.

Authors: Janssen Anna , Talic Stella , Gasevic Dragan , Kay Judy , Shaw Tim
Published: February 2021

BACKGROUND

There is an increasing amount of electronic data sitting within the health system. These data have untapped potential to improve clinical practice if extracted efficiently and harnessed to change the behavior of health professionals. Furthermore, there is an increasing expectation from the government and peak bodies that both individual health professionals and health care organizations will use electronic data for a range of applications, including improving health service delivery and informing clinical practice and professional accreditation.

OBJECTIVE

The aim of this research program is to make eHealth data captured within tertiary health care organizations more actionable to health professionals for use in practice reflection, professional development, and other quality improvement activities.

METHODS

A multidisciplinary approach was used to connect academic experts from core disciplines of health and medicine, education and learning sciences, and engineering and information communication technology with government and health service partners to identify key problems preventing the health care industry from using electronic data to support health professional learning. This multidisciplinary approach was used to design a large-scale research program to solve the problem of making eHealth data more accessible to health professionals for practice reflection. The program will be delivered over 5 years by doctoral candidates undertaking research projects with discrete aims that run in parallel to achieving this program’s objectives.

RESULTS

The process used to develop the research program identified 7 doctoral research projects to answer the program objectives, split across 3 streams.

CONCLUSIONS

This research program has the potential to successfully unpack electronic data siloed within clinical sites and enable health professionals to use them to reflect on their practice and deliver informed and improved care. The program will contribute to current practices by fostering stronger connections between industry and academia, interlinking doctoral research projects to solve complex problems, and creating new knowledge for clinical sites on how data can be used to understand and improve performance. Furthermore, the program aims to affect policy by developing insights on how professional development programs may be strengthened to enhance their alignment with clinical practice. The key contributions of this paper include the introduction of a new conceptualized research program, Practice Analytics in Health care, by describing the foundational academic disciplines that the program is formed of and presenting scientific methods for its design and development.

Authors: Setyawaty Rety , Dwiyanti Mela , Dewanto Dewanto
Published: February 2021

Secang wood (Caesalpinia sappan L.) is one of the local resources that contain natural pigments, namely brazilin. Brazilin is a pigment derived from Secang wood (Caesalpinia sappan L.) that is potentially used as a natural dye. This study aims to prove that Secang Wood (Caesalpinia sappan L.) can be applied as a dye in Compact Powder Blush On.The method for obtaining Secang wood (Caesalpinia sappan L.) extract uses the maceration extraction method with a sample of Secang wood (Caesalpinia sappan L.) of 250 gram and ethanol 96% then evaporated in a water bath with a temperature below 80 0C resulting in a yield of Secang wood (Caesalpinia sappan L.) extract of 27.87%. pH during the maceration process must be kept neutral, if it is not stable then it is added citric acid or sodium bicarbonate. The components of the Compact Powder Blush On are Talcum, Kaolin, Parrafin Liquid, Okside Zinc, Isopropyl myristate, and the addition of Secang wood extract (Caesalpinia sappan L.) with a concentration of 5%, 10%, 20%. Tests on preparations made include pH test, sticky power test, topical test, and stability test.The observations show that the Compact Powder Blush On preparation at a concentration of 5%, 10%, and 20% Secang wood extract (Caesalpinia sappan L.)  is pink, easily applied, has an average adhesion of 13.83%, produces a pink color when applying, and has a pH of 7. However, using Secang wood (Caesalpinia sappan L.) as a Blush On dye does not have color stability. Based on the results of the study it can be concluded that Secang Wood (Caesalpinia sappan L.) can be used as a natural dye Compact Powder Blush On, but additional ingredients are needed so that the color remains stable during storage at room temperature.

Background and objectives

Kidney involvement is frequent among patients with coronavirus disease 2019 (COVID-19), and occurrence of AKI is associated with higher mortality in this population. The objective of this study was to describe occurrence and significance of proteinuria in this setting.

Design, setting, participants & measurements 

We conducted a single-center retrospective study to describe the characteristic features of proteinuria measured within 48 hours following admission among patients with COVID-19 admitted in a tertiary care hospital in France, and to evaluate its association with initiation of dialysis, intensive care unit admission, and death.

Results

Among 200 patients with available data, urine protein-creatinine ratio at admission was ≥1 g/g for 84 (42%), although kidney function was normal in most patients, with a median serum creatinine of 0.94 mg/dl (interquartile range, 0.75–1.21). Median urine albumin-creatinine ratio was 110 mg/g (interquartile range, 50–410), with a urine albumin-protein ratio <50% in 92% of patients. Urine retinol binding protein concentrations, available for 85 patients, were ≥0.03 mg/mmol in 62% of patients. Urine protein-creatinine ratio ≥1 g/g was associated with initiation of dialysis (odds ratio, 4.87; 95% confidence interval, 2.03 to 13.0; P<0.001), admission to the intensive care unit (odds ratio, 3.55; 95% confidence interval, 1.93 to 6.71; P<0.001), and death (odds ratio, 3.56; 95% confidence interval, 1.90 to 6.54; P<0.001).

Conclusions

Proteinuria is very frequent among patients admitted for COVID-19 and may precede AKI. Low levels of albuminuria suggest a predominant tubular origin, confirmed by the elevated levels of urine retinol binding protein. Urine protein-creatinine ratio ≥1 g/g at admission is strongly associated with poor kidney and patient outcome.
Sympathy, Blame, and Just Allocation of Health Costs Entailed by Risky Conventional Lifestyles
Authors: Evans MDR
Published: February 2021

How does the general public feel about people suffering from lifestyle related conditions, and what do they see as a socially just division health costs for these conditions? Using data from random, nationwide surveys of Australians, 1989-2001 (n=8031) my structural equation model with multiple-item measurement and corrections for attenuation due to random measurement error predicts respondents’ ideal division of medical payment responsibility. The only significant sociodemographic influence is education, which inclines people towards governmental financial responsibility. Cultural and social-psychological factors have large effects. A net time trend favors individual responsibility. Blaming sufferers is strongly associated with favoring individual responsibility. By contrast, people who sympathize with the sufferers tend to favor government payments. Political party preference also matters: Partisans of the main conservative party tend to support individual responsibility. There are clear implications for the current COVID-19 epidemic, especially with regards to “social distancing” behavior.

Esta fina modulación de la expresión génica determina el fenotipo de los diferentes tipos celulares, su morfología, su funcionalidad y su habilidad de responder ante diversas condiciones. La regulación epigenética no implica cambios en la secuencia del DNA, pero sí en la generación de numerosos complejos proteicos capaces de modificar la estructura de la cromatina y así modular la expresión génica. La epigenética en los organismos es altamente regulada por varios factores que incluyen la dieta, el ambiente y la actividad física, entre otros. Además, bajo una condición de enfermedad o un estado saludable, así como durante el envejecimiento, se reportan diferencias entre los epigenomas de las células. De manera importante, el envejecimiento es un factor de riesgo directo para el desarrollo de enfermedades neurodegenerativas. En esta revisión presentamos brevemente un panorama general del proceso de regulación transcripcional y de los mecanismos epigenéticos, así como su relación con el proceso del envejecimiento. Alteraciones en los mecanismos epigéneticos son evidentes durante el avance de la edad, los cuales podrían tener alguna influencia en el desarrollo de enfermedades neurodegenerativas.

There are many difficulties that can be identified when students solve mathematic problems especially in solving probability word problems. This study was conducted to identify the major obstacles faced by matriculation college students while solving the probability of an event word problems. Seven college students were the sample for this case study. Clinical interviews are used as a data collection. This data collection technique was selected based on the researcher’s observation on the participants as they answered the probability word problem task. The task was given during the interview session. Semi structured interviews are used to obtain in depth information. Think-aloud analysis involves observations leading to individual behaviours in the oral or nonverbal form of participants and the researcher’s field notes. Participants were found to have difficulty interpreting probabilities. There are three categories of difficulties that have been identified, namely not knowing the meaning of the word, not knowing the nature of the probability and not being able to identify the goal of the probability word problem.

Los resultados del trabajo interdisciplinar hacen parte de nuestra vida cotidiana. Descubrimientos como la estructura del ácido desoxirribonucleico (ADN), la resonancia magnética, la bomba atómica, el láser para la cirugía de ojos, la “revolución verde”, el radar, el genoma humano, entre muchos otros ejemplos [1], son producto de este tipo de alianzas, y si le sumáramos aquellos que se encuentran en etapa de laboratorio o con resultados casi a punto, pero con pequeñas imprecisiones, podríamos asegurar que los mayores avances se encuentran cuando nos permitimos ver el problema desde otra perspectiva, desde otras disciplinas.
