Published: April 2019

Early maturing peach (Prunus persica) cultivars can fetch good market value but face a lot of post-harvest problems that lead to the post-harvest losses. The 1-methylcyclopropene (1-MCP) can provide new insights into plant ethylene responses and extend the shelf life and quality of fruits. Therefore, fruits of peach cultivar ‘Early Grand’ were dipped in various concentrations of 1-MCP (0, 0.3, 0.6 and 0.9 µg l–1), stored for 40 days at 8 ±2°C with 50% relative humidity and analyzed the fruits for physicochemical attributes at 10 days interval. The highest concentration of 1-MCP at 0.9 µg l–1 significantly improved the activity of antioxidants, catalase, free radical scavenging assay and total phenols. However, the peach fruits treated with 1-MCP at 0.6 µgL–1 was effective in retaining the ascorbic acid, lowering the weight loss and fruit decay. Therefore, peach fruits can be treated with 1-MCP (0.6 µg l–1) solution for prolonging its shelf life up to 40 days under low temperature.

Published: April 2019

OBJECTIVE

To develop and analytically validate a liquid chromatography–tandem mass spectrometry method for measurement of endogenous trans-4-hydroxy-l-proline concentrations in canine serum and to assess serum trans-4-hydroxy-l-proline concentrations in dogs with chronic hepatitis.

SAMPLE

Serum samples obtained from 20 dogs with histopathologically confirmed chronic hepatitis and 20 healthy control dogs.

PROCEDURES

A liquid chromatography–tandem mass spectrometry method for quantification of trans-4-hydroxy-l-proline concentration was developed and assessed for analytic sensitivity, linearity, accuracy, precision, and reproducibility. Serum concentration of trans-4-hydroxy-l-proline in dogs with chronic hepatitis and healthy control dogs was measured.

RESULTS

Observed-to-expected ratios for dilutional parallelism ranged from 72.7% to 111.5% (mean ± SD, 91.3 ± 19.6%). Intra-assay and interassay coefficients of variation ranged from 2.1% to 3.0% and 3.2% to 5.3%, respectively. Relative error ranged from −2.3% to 7.8%. Trans-4-hydroxy-l-proline concentrations were significantly lower in serum obtained from dogs with chronic hepatitis (median, 0.24 ng/mL; range, 0.06 to 1.84 ng/mL) than in serum obtained from healthy control dogs (median, 0.78 ng/mL; range, 0.14 to 4.90 ng/mL).

CONCLUSIONS AND CLINICAL RELEVANCE

The method described here for the quantification of trans-4-hydroxy-l-proline concentration in canine serum was found to be sensitive, specific, precise, accurate, and reproducible. Dogs with chronic hepatitis had significantly lower serum trans-4-hydroxy-l-proline concentrations than did healthy control dogs, possibly as a result of altered hepatic metabolism of amino acids.

OBJECTIVE

To compare ultracentrifugation, precipitation, and membrane affinity chromatography methods for isolation of extracellular vesicles (EVs) from canine plasma samples and to identify suitable reference genes for incorporation into a quantitative reverse transcription PCR assay of microRNA expression in plasma EVs of healthy dogs.

ANIMALS

6 healthy Beagles.

PROCEDURES

Plasma samples were obtained from each dog, and EVs were isolated from 0.3 mL of these samples via ultracentrifugation, precipitation, and membrane-affinity chromatographic methods. Nanoparticle tracking analysis was performed to determine the concentration and size distribution of EVs isolated by the ultracentrifugation method. Expression levels (cycle threshold values) of 4 microRNAs (let-7a, miR-16, miR-26a, and miR-103) were then compared by means of quantitative reverse transcription PCR assay. Three statistical programs were used to identify the microRNAs most suitable for use as reference genes.

RESULTS

Results indicated that ultracentrifugation was the most stable of all 3 methods for isolating microRNAs from 0.3 mL of plasma. Nanoparticle tracking revealed that EV samples obtained by the ultracentrifugation method contained a mean ± SD of approximately 1.59 × 1010 vesicles/mL ± 4.2 × 108 vesicles/mL. Of the 4 microRNAs in plasma EVs isolated by ultracentrifugation, miR-103 was the most stable.

CONCLUSIONS AND CLINICAL RELEVANCE

The ultracentrifugation method has potential as a stable method for isolating EVs from canine plasma samples with a high recovery rate, and miR-103 may provide the most stable reference gene for normalizing microRNA expression data pertaining to plasma EVs isolated by ultracentrifugation.

This research is motivated by a "unique" phenomenon from of the role of the profession internal auditors. For Internal auditors of  Internal Control Unit (SPI) in a non-profit organization, especially in an Higher Education Institution, the uniqueness has the potential to place it in a situation of independence dilemma. The purpose of this study is to understand the reality of the independence dilemma faced by SPI auditors as a result of the conditions and work environment. In order to explore the auditor's understanding of SPI, phenomenology is employed as methodology, under interpretive paradigm as the umbrella of this research. Exploration of understanding and awareness is done using Epoche. The results of the study revealed that the SPI auditor faced a situation of independence in various forms: (1) the negative auditing stigma in the form of the awarding of "kambing hitam" to SPI raises a dilemma for auditors and disturbs the working spirit of the SPI auditor, on the other hand if implemented improperly will be contrary to the obligation and further aggravate the negative stigma already attached; (2) there is a phenomenon of impropriety (abuse) on audit guidelines that has not been fully implemented and not evaluated to provide ethical consideration in the future; (3) the existence of obedience pressure in the form of "suspension" the rector signs the SPI examination report. due to the term audit conception that has not been agreed upon.
TUJUH BELAS TAHUN STUDI AKUNTANSI ZAKAT DI INDONESIA: SEBUAH REVIU SISTEMATIK DAN SARAN UNTUK RISET DI MASA MENDATANG
Authors: Sofyani Hafiez
Published: April 2019

Roughly 17 years have passed since the first article on zakat accounting was written by Harahap and Yusuf (2002). Until 2019 today, the average accounting zakat articles published in accredited journals ranking 2 and 3 are only 1.53 per year. This indicates that attention to the issue of accounting for zakat by accounting academics is low. Various problems related to zakat accounting research are presented in this paper, starting from the shallowness of the study, there was no connection between one research with other research, and monotonous topics which have no follow-up on research design that should be more in-depth. Many papers also did not really present practical and theoretical contributions. Various research paradigms which are actually very valuable to be employed in zakat accounting research have also not been explored further. Departing from the various problems, this paper tries to provide direction for future research regarding zakat accounting issue. This paper is a systematic review of published research as well as developments in academic and practices issues in the field related to zakat accounting and Zakat Management Organization (OPZ). Review results offers three points of improvement for future studies, namely the proposal of several contemporary issues/topics that need to be investigated, the research paradigm recommended to be applied, and theories or concepts that need to be tested related to research on zakat accounting.

Published: April 2019

Traditional natural products discovery workflows implying a combination of different targeting strategies including structure- and/or bioactivity-based approaches, afford no information about new compound structure until late in the discovery pipeline. By integrating a MS/MS prediction module and a collaborative library of (bio)chemical transformations, we have developed a new platform, coined MetWork, that is able of anticipating the structural identity of metabolites starting from any identified compound. In our quest to discover new monoterpene indole alkaloids, we demonstrate the utility of the MetWork platform by anticipating the structures of five previously undescribed sarpagine-like N-oxide alkaloids that have been targeted and isolated from the leaves of Alstonia balansae using a molecular networking-based dereplication strategy fueled by computer-generated annotations. This study constitutes the first example of non peptidic molecular networking-based natural product discovery workflow, in which the targeted structures were initially generated, and therefore anticipated by a computer prior to their isolation.
Understanding the mechanism of enhanced cycling stability in Sn-Sb composite Na-ion battery anodes: in-operando alloying and diffusion barriers
Authors: Kalisvaart W. Peter , Xie Hezhen , Olsen Brian , Luber Erik , Buriak Jillian
Published: April 2019

Sn-Sb composites are of great interest for high capacity sodium ion batteries due to their high stability, but because multiple phases and alloyed compositions are formed during cycling, the roles of each are challenging to deduce. In this work, two approaches were taken to investigate the importance of β-SnSb formation on the cycling stability of Sn-rich Sn-Sb composite sodium-ion battery (SIB) anodes. First, to tease out the role of each component, thin layers of amorphous silicon with thicknesses ranging from 0.5 to 10 nm, were incorporated between Sn and Sb layers, of equal thicknesses. Silicon has low solubility in both tin and antimony, and thus acts as a barrier layer that can interfere with the formation of Sn-Sb alloys. The equivalent composition of this sandwich structure was Sn53Sb47. Upon electrochemical cycling, a clear correlation between capacity retention and Si thickness was observed, and it was found that a 1 nm thick Si layer was sufficient to inhibit the formation of the β-SnSb intermetallic, resulting in loss of the capacity of the tin layer after a few tens of cycles. The second approach involved capping a Sn film with increasingly thicker Sb layers. Thicker antimony layers were found to have a large positive influence on cycling stability with a marked drop-off in the capacity retention when there is not enough Sb to fully convert the bilayer into β-SnSb. These results point to the necessity of the Sn and Sb being in intimate contact prior to cycling for the β-SnSb phase to form in-operando, which is necessary for the excellent capacity retention of the Sn-Sb system.

Published: April 2019

Antibiotics are used to cure the illness caused by pathogenic microbes. The resistance towards such antibiotics is becoming a serious concern in the present time. The frequency of drug resistance is increasing in hospitals. This aptitude to develop resistance against antibiotics has become a serious threat to the patients that are already hospitalized, making them more prone to infections and increased complications of already existing medical conditions. It can also lead to a high mortality rate in hospitals. The present work is designed to isolate microbes from the hospital environment to check the sensitivity against various antibiotics. For the isolation, aerosol-based air samples were taken by exposing sterile Petri plate at the OPD and general ward for about 10 minutes after that the plates were taken to the lab and incubated at 37oc for 24 hours. Pure cultures were obtained by sub culturing the isolates onto fresh sterile nutrient agar plates. The clinical isolates were tested for antibiotic sensitivity test by using Dodeca G- V Plus disk (Himedia). The isolates were identified on the basis of microscopic and VITEK 2 based identification. Total of four bacteria Kocuria kristinae, Sphingomonas paucimobilis, Pantoea spp. and Staphylococcus vitulinus were isolated that showed variation in antibiotic-resistant pattern.

The placenta is an essential component for maintaining pregnancy and the proper development of the fetus. Among the complications of pregnancy hypertensive disorders ranks first worldwide for maternal mortality and morbidity. Throughout gestation, placenta undergoes a lot of changes in its morphology and morphometric parameters. The aim of the present study to examine the effect of maternal parameters such as age, parity, height, pre-gestational weight, BMI and a gestational week on placental morphology and morphometric parameters. 80 pregnant women aged between18-40, parity1 - 4, gestational age between 37weeks-40weeks, who attended the antenatal clinic of the hospital and delivered by either vaginal route or caesarean section were included. Placental and maternal parameters were assessed using standard methods. In the present study pre-gestational weight shows a significant positive correlation with the thickness in both groups and significant negative correlation with the placental diameter in the normal placenta Height of the mother also shows a statistically significant negative correlation with the number of maternal cotyledons. Positive as well as negative correlation exists among variables. Longitudinal studies in more samples are required, and results cannot be generalized. Examination placental parameters and its correlation with the maternal parameters will help to manage future pregnancies, fetal outcome and maternal health.
Evaluation of renal and liver function in petrol station workers in Kirkuk city
Authors: Dlawer Abdulhammed Ahmad AL-Jaff
Published: April 2019

A cross-sectional study to evaluate the effects of occupational petrol exposure on the kidney and liver of petrol station workers in Kirkuk city was done. 29 petrol pump workers who were continuously exposed to petrol for at least one year in the Kirkuk city having no medical history and 10 healthy age-matched controls who were never exposed to petrol were enrolled. These serum parameters of both the groups were compared by the Mann-Whitney U test. Since all the parameters studied were normal in the workers exposed to petrol, it can be concluded that petrol did not affect their liver and kidney health. However, higher levels of serum cholesterol, TG, and LDL in the petrol station workers as compared to the controls are suggestive of higher risk of developing liver damage. Larger studies should be conducted to validate the findings of the present study further.

Published: April 2019

Eclipta Alba has been used in traditional and folklore medicine to treat Hyperlipidemia and hepatic disorders. The present study was aimed to investigate the Antihyperlipidemic and hepatoprotective potentials of Eclipta Alba in high-fat diet -induced Albino rats and to determine the underlying mechanism.  A total of 30 adult albino rats of Wistar strain weighing 165–215 g were utilized. Animals were treated with high-fat diet for 8 weeks followed by post-treatment of E. Alba for 1 week, 2 weeks, and 3 weeks, respectively. After 12 h of fasting on the last day of the experiment, serum blood samples were collected in EDTA vials and processed for biochemical analysis.  A significant decrease in levels of total cholesterol and triglycerides was noted on animals treated with E. alba compared to high-fat diet animals. Treatment of hypercholesterolemic rats with E. Alba showed a marked decrease of serum low-density lipoprotein (LDL) and very LDL cholesterol concentrations compared to the hypercholesterolemic rats. High-fat diet feeding worsened the levels of serum glutamic oxaloacetic transaminase, serum glutamic pyruvic transaminase, and alkaline phosphatase enzymes, whereas the same markers were significantly improved by supplementation with E. alba compared to the normal group.  E. alba acts as an antihyperlipidemic agent in hyperlipidemic conditions and helps for better health.

Published: April 2019

The exclusive, low-cost nominal technology for the meagre entrepreneurs of Silk dyeing effluent has been planned and executed. Environmental pollutants exit like Silk dyeing effluent are destructive and needs a high-cost Common Effluent Treatment Plant (CETP) to achieve Zero effluent discharge limits which are not reasonably priced for a low venture capitalist. The Green leafy vegetable Brassica juncea sowed seeds were treated in pot study with fresh water, raw Silk dyeing effluent and Biotreated effluent (with Pseudomonas fluorescens and Azospirillum sp. biofertilizers separately). After 45th days the GLV’s extracts Brassica juncea were grown in fresh water (BJN), in crude effluent (BJE) and in biotreated effluent (BJT) were subjected to UV, FTIR and HPLC analysis. Thus from the functional group studies by FT-IR, the alcohol, alkane, alkyl halide and amine groups were found in GLV irrespective of the treatments, even in crude effluent, the plants managed to synthesize these organic compounds. The isocyanide group was found only in B. juncea, grown in fresh water, which was unable to synthesize isocyanide group in plants grown in crude effluent and biotreated effluent. While the biotreated B. juncea methanolic extracts had shown two peaks of similar to the freshwater B.juncea methanolic extracts whereas the crude effluent had its effect in HPLC Analysis. So it clearly indicates that the effluent's effects have been encountered by the Pseudomonas fluorescens.
Urinary N-telopeptide- A diagnostic Test or A Screening Test?
Authors: Ganesan G Ram  , Jambu N
Published: April 2019

Dual-energy X-ray absorptiometry (DEXA) scan is the gold standard investigation for diagnosing osteoporosis. The limitations of "gold standard" Dual-energy X-ray absorptiometry scan were many. The aim of this study is to find whether urinary n telopeptide can be used to diagnose osteoporosis — prospective cohort study done at Sri Ramachandra Medical University between August 2014 to December 2018. The study was done amongst the postmenopausal females and older males who came to the University hospital as an inpatient or an outpatient with suspected osteoporosis. We had 110 persons participated in the study. The patients were divided into two groups. Group, I was cases whose Dexa scan was osteoporosis/ osteopenia, and Group II was a control that had standard Dexa. The results from Dexa Scan are taken as the gold standard against urinary n telopeptide and a 2x2 table formed. Sensitivity, specificity, positive predictive value, likelihood ratio, area under ROC curve will be calculated. The mean value of urinary N Telopeptide in the case group was 182.5 and in control group was 49.8. The ROC curve was formed and cut off was calculated to be 71. Urinary N telopeptide can very well be considered as a diagnostic test and can’t be considered as a gold standard diagnostic test as there is some limitation as it is a bone resorption biomarker having some pre-analytical and biochemical variability which can alter the results. It can be used as an adjuvant and as a screening test along with gold standard Dexa in diagnosing osteoporosis.

Há um número grande de trabalhos de investigação com diferentes abordagens e metodologias que procuraram descobrir os motivos para o fracasso generalizado dos alunos na disciplina de Cálculo Diferencial e Integral. Mas, há ainda poucos trabalham que versam sobre o olhar do aluno universitário sobre essa dificuldade. Apresentaremos nesse texto, especificamente, os dados dos alunos referentes ao conceito de limite com a esperança de que os mesmos possam sensibilizar os professores que ensinam essa disciplina.
A epiderme do pensamento:
Authors: Pereira Marcelo De Andrade
Published: April 2019

O presente estudo pretende investigar a concepção nietzscheana da Tragédia Clássica. Intui, portanto, apresentar as formas de experiências por ela engendradas, assim como as formas que ela engendra de pensamento e experiência. Essas formas remetem, por certo, a um universo de pensamento e experimentação (ética e estética) qualitativamente distinto do nosso. Servem-nos, entretanto, como fonte para se problematizar a prática educativa contemporânea em face da dimensão estética do viver e do próprio pensar. Partiremos assim, da hipótese de que Nietzsche postula nas noções de dionisíaco e apolíneo as formas de configuração da experiência no pensamento e do pensamento na experiência. Em outras palavras, buscaremos explicitar o enlace entre a experiência e o pensamento naquela que segundo Nietzsche seria a grande obra de arte grega, a tragédia.

CONSENSO Y CONFLICTO EN LA EDUCACIÓN POLÍTICA EN LA ESCUELA. RELECTURAS EN TORNO DEL DISCURSO PEDAGÓGICO. DEL PRIMER PERONISMO.
Authors: Mamilovich Carolina
Published: April 2019

Neste trabalho aborda-se a questão da educação política nas instituições escolares argentinas com o caso paradigmático do discurso pedagógico do primeiro peronismo como ponto de partida. Também, como parte dessa abordagem, tenta-se contrapor duas correntes interpretativas que baseadas nas suas próprias construções teóricas instituíram modelos diversos de subjetivação política: por um lado, a perspectiva liberal-funcionalista que privilegia a conciliação e o consenso; e, por outro, o enfoque nacional-populista que concede primazia ao conflito e ao antagonismo.

Perspective of the Legal Basis of NPC’s Discussion and Decision-making Power on Major Issues
Authors: Liao Yuan
Published: April 2019

The decision of local people's congresses to discuss major issues is a basic right granted to local people's congresses by the Chinese Constitution and laws. However, in practice, the implementation of the power of deliberation of major issues by local people's congresses is worrying. By applying the theory of Chinese traditionalism and unity in the theory of law, the theory of “sovereignty in the people” in the social contract theory of Western natural law school, Austin's “legal command theory” in Western positivist law and Hart's “recognition” “Rules theory” to argue that the integrity of rights necessarily involves the dual factors of decision-making and execution. At the same time, the existence and operation of the law always reflects the development of the political system. The realistic political situation requires us to make more precise and meticulous refinement of the external form and specific technical links of the legal system, and to coordinate the rules to make up the legal theory and Conflicts and conflicts in legal practice help to reform social institutions.

المذهب الحنفي ومشيخة الإسلام الحنفية في الجزائر من فتح شمال إفريقيا إلى غاية الاستقلال
Authors: ZAHER Fares , DUMAN Soner
Published: April 2019

تتميز البلاد الجزائرية بتنوع التركيبة البشرية وشساعة
مساحتها، وهو ما أعطى مجالا للتوسع العلمي والإحتكاك المعرفي، وتجسد ذلك في المذهب
الحنفي السلطة الروحية للدولة العثمانية في المغرب الأوسط (الجزائر حاليا)، لذلك قمنا
بتسليط الضوء في مقالتنا هذه على مراحل نشأته، وأبرز علماءه وإنتاجهم العلمي وموقع
كل ذلك من تاريخ الجزائر الديني والمعرفي، فذكرنا تواجد المذهب الحنفي في مرحلة ما
قبل الحكم العثماني وأثنائه والمتصدين للفتوى الحنفية آنذاك، ثم المذهب الحنفي في
عهد الإحتلال الفرنسي إلى غاية الإستقلال،كما تعرضنا لأحوال
هذا المذهب ومساجده ومراكز تمويله المتمثلة في الأوقاف، وقمنا بترجمة لأبرز أعيانه
في الجزائر، ومقارنته مع المذهب المالكي السائد في الجزائر، وفي الأخير خاتمة وضحنا
فيها جميع النتائج المتوصل إليها، وبعدها المصادر والمراجع المعتمدة في البحث،
وبذلك تنكشف دعائم السلطة الروحية للمذهب الحنفي في العهد العثماني والاحتلال
الفرنسي، وتظهر المؤلفات والآثار، فاستعنا بالله عزوجل وعزمنا على جمع شتات هذا
الموضوع بما يعطيه حقَه، وبما يوضح مبهمه ويكشف عن مستُوره، فكانت بذلك دراسة
شاملة لما بحث وزيادة، فاستخلصنا نتائج جيدة من هذا البحث منها " أن المذهب
الحنفي في الجزائر من المذاهب التي تدعمت أكثر بدخول العثمانيين، كما أن غالبية من
تقلد منصب شيخ الاسلام الحنفي في الجزائر من الأتراك تميزوا بمستوى علمي جيد، وكان
علمهم تطبيقيا أكثر منه تأليفيا ونظريا، وعلى الرغم من ذلك فقد أثرى المذهب الحنفي
المكتبة الجزائرية بكتب قيمة وفي مختلف المجالات، لذلك اقترحنا في الخاتمة أنّه
لابد على باحثي عصرنا من جمع مختلف مؤلفاته وتحقيقها والإحاطة أكثر بقضاياه
ومسائله
