Published: March 2019

The identification and evaluation of tea [Camellia sinensis (L.) O. Kuntze] germplasm resources are of great significance for tea plant breeding. In recent years, various methods, such as morphology, biochemistry, molecular markers, and sensory evaluation, have been used to evaluate the tea germplasm resources. However, the evaluation of tea germplasms based on metabolomics is rarely reported. In this study, we first measured the main agronomic characters and biochemical components of tea young shoots in spring, and then analyzed the metabolic profiles using gas chromatography-mass spectrometry (GC-MS) and liquid chromatography with tandem mass spectrometry (LC-MS/MS). The results indicate that tea germplasm accessions QN3 and QN38 had excellent agronomic traits with early germination and high yield compared with HM. The biosynthesis of flavonoids in young shoots of QN3 was more vigorous, especially for the biosynthesis of epigallocatechin gallate (EGCG) and epicatechin gallate (ECG). Accession QN3 had highest content of luteoloside, myricetin and rutin, whereas QN38 had highest content of most amino acids. On the basis of sensory quality evaluation, accession QN3 and QN38 all had higher total quality scores. By using these approaches, we found that QN3 and QN38 are excellent breeding materials with high yield and high quality for making green teas. We also believe that the evaluation system constructed by the approaches described here is suitable for the identification of tea germplasms.

Published: March 2019

This study investigated the carboxymethylcellulose (CMC)-based edible coating effects on some quality parameters and enzyme activities of plum fruits (Prunus domestica L. cv. Golden drop) during their shelf life. Three concentrations of CMC (0.5%, 1%, and 1.5%), plasticized with glycerol (0.3% w/v), were applied to plum fruits plus a control treated with only distilled water. The results demonstrate that the CMC-based edible coating was significantly effective in maintaining firmness and titratable acidity (TA); vitamin C, anthocyanin, and flavonoid content; and the antioxidant capacity of plum fruits. Enzymatic activity was affected significantly by the coating. Peroxidase (POD) activity increased, and polyphenol oxidase (PPO) and polygalacturonase (PG) decreased. In general, the formulation consisting of 1% CMC showed the best results in most of the measured parameters. Taking into account the positive effects on qualitative and biochemical characteristics of CMC-based edible coatings on plums, their application can be a potentially promising method to enhance the shelf-life of this fruit.

Published: March 2019

Malanga (Colocasia esculenta) is a plant genetic resource that requires biotechnological strategies for conservation and propagation. One time-, labor-, and space-saving option is in vitro conservation and regeneration. The objective of this study was to develop a protocol for in vitro regeneration and conservation of germplasm of C. esculenta var. criolla. For conservation through minimal growth, we assessed several concentrations of Murashige and Skoog (MS) medium (one-third, one-half, and three-quarter strength), the growth retardant ancymidol (0, 1, 2, and 3 mg·L−1), and the osmoregulator polyethylene glycol (PEG-8000 mw) at different concentrations (0, 10, 20, and 30 g·L−1). For in vitro conservation, the percent survival, shoot number and length, and number of leaves and roots per explant were evaluated after 24 weeks. For in vitro regeneration, different concentrations of thidiazuron (TDZ: 0, 0.5, 1, 1.5, and 2 mg·L−1) and 6-benzylaminopurine (BAP; 0, 1, 2, 3, and 4 mg·L−1) were evaluated. After 4 weeks of cultivation, the percent response, shoot number, and number of leaves per explant were recorded. During in vitro conservation, it was noted that the treatment including 2 mg·L−1 ancymidol resulted in a retarded development, without affecting the survival of the C. esculenta germplasm. With regard to shoot regeneration, 7.60 shoots per explant were obtained using 2 mg·L−1 TDZ. Finally, 98% survival was achieved during the acclimatization process. This study will contribute to the establishment of genetic improvement programs through in vitro conservation and propagation of this valuable plant genetic resource.

Published: March 2019

Producing consumer packaging, which would meet the modern requirements in a comprehensive manner, while ensuring the needs of a consumer, a manufacturer and society as a whole, is currently one of the most important issues. In the context of developing a socially responsible society, the transition from classical marketing schemes to the social and ethical marketing is important for producers. The article defines the features of consumer packaging as a marketing tool based on theoretical generalization and survey among the city of Lutsk residents. The author’s vision of the packaging strategy and the product strategy interaction in the context of socially oriented marketing is presented. The possible options of packaging recycling are outlined: use of returnable packaging; utilization of packaging and the use of appropriate materials that are subject to recycling; use of packaging for other purposes.

Published: March 2019

The occurrence of pharmaceuticals in the drinking water is a growing concern in China. In this study, we determined the concentration and distribution of 59 selected pharmaceuticals in raw, finished, and tap water samples from 79 drinking water treatment plants (DWTPs) in 15 cities, encompassing seven large river basins in China, using solid-phase extraction pretreatment and ultra-high-performance liquid chromatography–tandem mass spectrometry analysis. Forty-seven pharmaceuticals were detected in raw water samples, with detection rates of 1.27–96.20% and average concentrations of 0.09–128.87 ng/L. Forty-three pharmaceuticals were detected in finished water samples, with detection rates of 1.27–96.20% and average concentrations of 0.07–59.17 ng/L. Forty-two pharmaceuticals were detected in tap water samples, with detection rates of 1.27–94.94% and average concentrations of 0.07–58.43 ng/L. Purification methods implemented by DWTPs are capable of removing some pharmaceuticals from water treatment systems; however, low concentrations of pharmaceuticals were detected in drinking water, raising concerns about the possible human health implications of long-term exposure to low-dose pharmaceuticals. The detection and quantification of pharmaceuticals in municipal water samples presented in this study represent the most extensive analysis of commonly used pharmaceuticals and personal care products located in Chinese river basins.
“MENINAS DANADAS”
Authors: Tota Martinho , De Lima Greilson José , Véras Cassandra
Published: March 2019

Este artigo, construído a partir de fragmentos registrados durante pesquisas realizadas em pequenos municípios localizados no Litoral Norte do estado da Paraíba, trata de questões de sexo e gênero envolvendo crianças e adolescentes sexualmente “exploradas”, jovens mulheres engajadas na prática prostitutiva e “meninas danadas”, isto é, mulheres igualmente jovens, não diretamente inseridas no mercado de sexo comercial, mas que ainda assim são suscetíveis aos mesmos processos de rotulação aos quais são submetidas as “verdadeiras” profissionais do sexo. Embora cada uma dessas situações guarde particularidades que as distinguem, em todas elas está em jogo uma tensão entre as vulnerabilidades implicadas nas identidades de gênero e a autonomia feminina. Ou seja, os discursos e as representações “vitimistas” muitas vezes esquecem-se dos desejos e da capacidade a que os sujeitos mulheres, mesmo neste contexto específico, têm de obedecer ou resistir.

A INSTITUCIONALIZAÇÃO DA DIFERENÇA
Authors: Souza Sandra Cristina Morais de , Rangel Mary
Published: March 2019

Neste texto, centramos nossa reflexão na emergência do termo inclusão, buscando entendê-lo como um processo social, econômico, histórico e cultural produzido pela modernidade. Ao abordar o termo inclusão é necessário articula-lo a outro termo que ganhou espaço e destaque - diferença. Na tentativa de discutir sobre esses termos, procuramos, neste breve ensaio, envolver alguns aspectos sobre as tentativas de institucionalizar a diferença e suas práticas de governamento na sociedade moderna. Para tratar os conceitos em questão, faço uma conexão teórica com Michel Foucault, por considerá-lo como uma das referências principais, pois, através de suas reflexões sobre a sociedade moderna e suas instituições, abriu-se a possibilidade de um olhar crítico sobre os sujeitos construídos por tais instituições e sociedade. As noções de biopolítica e normalização nos ajudam a trazer tais questionamentos sobre a construção do sujeito social. Em síntese, o caminho para os estudos sobre o tema em questão pressupõe um aprofundamento nos meandros que regulam as políticas inclusivas na educação e as práticas de governo que vêm engendrando discursivamente esses saberes e fazeres.
Efficacy and Safety of Dipeptidyl Peptidase-4 Inhibitors in Kidney Transplant Recipients with Post-transplant Diabetes Mellitus (PTDM)- a Systematic Review and Meta-Analysis
Authors: Abdelaziz Tarek Samy , Ali Ahmed Yamany , Fatthy Moataz
Published: March 2019

Background:

Kidney transplant recipients may develop post-transplant diabetes mellitus
(PTDM). Dipeptidyl peptidase 4(DPP-4) inhibitors are evolving agents in the management of patients
with diabetes mellitus.

Aims:

To evaluate the efficacy and safety of DPP-4 inhibitors in the management of post-transplant
diabetes mellitus (PTDM) in renal transplant recipients.

Methods:

We performed a systematic search of the electronic databases using keys words and Mesh
terms. Data were extracted and reviewed using structured proforma. A comprehensive review of the
eligible studies was performed independently by each of two reviewers; conflicts were resolved by the
third reviewer. The primary efficacy endpoint was the difference in glycosylated hemoglobin (HbA1c)
comparing any of the DPP-4 inhibitors to either placebo or other hypoglycaemic agent. The primary
safety endpoints were the worsening of graft functions and change in Tacrolimus trough level. We performed
the Random effect model using standardised mean difference.

Results:

We identified seven studies that were eligible for the systematic review; only one study compared
Sitagliptin to insulin Glargine. One study involved head to head comparison of three DPP-4 inhibitors.
The other five studies were pooled in the meta-analysis. DPP-4 inhibitors had a favourable
glycemic effect as measured by HbA1c when compared to either placebo or oral anti-hyperglycemic
medications (standardised mean difference in HbA1c = -0.993, 95% CI= -1.303 to -0.683, P=0.001).
DPP-4 inhibitors use did not result in significant change in eGFR ((standardised mean difference =
0.147, 95% CI= -0.139 - 0.433, p=0.312).) nor Tacrolimus level (standardised Mean Difference= 0.152,
95% CI= -0.172 to 0.477, P=0.354).

Conclusion:

Current evidence supports the short term efficacy and safety of DDP-4 inhibitor agents
in the management of post transplantation diabetes mellitus (PTDM) in kidney transplant recipients.
However, more RCTs are required to investigate the long-term safety and efficacy of these agents in
kidney transplant recipients.

Background:

Female Sex Workers (FSW) have increased vulnerability to viral hepatitis B, C and D transmission. Our study aimed to assess the seroprevalence of hepatitis B, C and D viruses and their associated factors among FSW in Ouagadougou, Burkina Faso.

Methods:

This is a cross-sectional study among FSW at least 18 years old in Ouagadougou, Burkina Faso. Data were collected from February 2013 to May 2013 using Respondent-Driven Sampling (RDS). Hepatitis B, C, and D tests were performed on FSW storage serums using fourth generation ELISA kits. Survey-weighted bivariate and multivariate logistic regression analyses were performed using Stata version 14 to identify factors associated with viral hepatitis infections.

Results:

Population-weighted prevalence of viral hepatitis infections in FSW was respectively 18.2% (95%CI: 14.4-22.9) for Hepatitis B Virus (HBV), 10.6% (95%CI: 07.5-14.8) for Hepatitis C Virus (HCV) and 1.5% (95Cl: 0.2-10.3) for Hepatitis D Virus (HDV). Factors independently associated with HCV include positive HIV status, inconsistent condom use during the last 12 months, condom reuse with clients, sex with clients in the street, bars or public gardens. No sociodemographic or behavioral factors were independently associated with HBV infection.

Conclusion:

The prevalence of HBV and HCV was high among FSW and the prevalence of HDV was relatively low in this group in Burkina Faso. These findings suggest urgent and comprehensive prevention of these viruses through education for safer sex and behaviors, and immunization against HBV for FSW.

Published: March 2019

Observation is argued as the most suitable technique to assess the execution of authentic assessment. Unfortunately, it requires great amount of time and money. We need an alternative. Therefore, the purpose of this study was to develop an instrument in the form of a student assessment sheet on the implementation of authentic assessments in Mathematics subjects. This research is a development research that uses standard procedures for developing instruments. The result of the analysis with Aiken’s formula showed that every item of the instrument was in a good category. The result of the analyses using Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and Multitrait-Multimethod showed that the instrument had good construct validity. The result of reliability estimation using Cronbach Alpha  (α) also showed that the instrument was in the reliable category. Thus, it can be concluded that the instrument in the form of student assessment sheets for assessing the implementation of authentic assessment in junior high school Mathematics learning is highly valid and reliable, which means that the developed instrument can replace the equivalent observation sheet.

Published: March 2019

Kolonlar deprem etkisi altında tersinir ve tekrarlı yüklere maruz kalan eksenel yük elemanlarıdır. Bu karmaşık yükleme durumu etkisinde kolonların davranışının analizi oldukça önemli hale gelmektedir. Deprem sonrası göçme veya ağır hasara uğramış yapılarda, oluşan hasarların kolon sargılama eksikliklerinden kaynaklandığı görülmüştür. Bu sebeple sargılamanın kolon davranışına olan etkisi araştırmacıların ilgisini çeken önemli konular arasında yer almaktadır. Bu çalışmada, sargı tipinin kolon davranışına etkisini inceleyen Saatçioğlu ve Özcebe (1989) tarafından yapılmış kolon deneyleri numune olarak seçilerek, açık kaynak kodlu sonlu elemanlar programı OpenSees ile seçilen kolonların sayısal analizi yapılmıştır. Sayısal analiz yapılırken numuneleri doğru temsil edecek eleman ve malzeme modelleri seçilmiştir. Oluşturulan sayısal modeller deprem yükleri etkisi altında analiz edilmiş, elde edilen sonuçlar mevcut deneysel çalışmanın sonuçları ile karşılaştırılmış ve sonuçların birbiri ile uyumlu olduğu görülmüştür.

Authors: Wu Chih-Jen , Lin Cheng-Jui , Chen Ying-Ying , Wu Pei-Chen , Pan Chi-Feng , Shih Hong-Mou , Chou Li-Hua
Published: March 2019

BACKGROUND

Cardiovascular (CV) events are the major cause of morbidity and mortality associated with blood pressure (BP) in hemodialysis (HD) patients. BP varies significantly during HD treatment, and the dramatic variation in BP is a well-recognized risk factor for increased mortality. It is important to develop an intellectual system capable of predicting BP profiles for real-time monitory.

OBJECTIVE

Our aim was to build a web-based system to predict the systolic blood pressure (SBP) change during hemodialysis process.

METHODS

This study was based on a large stream of HD parameters collected from a dialysis equipment connected to the Vital Info Portal gateway and linked with the demographic data stored in the hospital information system. The data set was divided into three groups - training, test and new patients. The training group was useful to build a multiple linear regression model, in which the SBP change was the dependent variable and the dialysis parameters and demographic data were the independent variables. We used the test and new patient groups to evaluate the model performance using coverage rates in different thresholds. A web-based interactive system based on the model was built for visualizing the prediction performance.

RESULTS

A total of 542,424 BP records were used in the model building. The accuracy was greater than 80% in the prediction error range of 15%, and 20mmHg of true SBP in the test and new patient groups for the SBP change model suggested a good performance of our prediction model. In the case of absolute SBP values (5, 10, 15, 20 and 25 mmHg), the accuracy of SBP prediction increased as the threshold value augmented.

CONCLUSIONS

This database supported the application of our prediction model in reducing the frequency of intradialytic SBP variability, and therefore, it could aid in the clinical decision when a new patient undertakes HD treatment. Whether the introduction of SBP prediction intelligent system can lower CV events in HD patients, it needs further investigations.

Published: March 2019

Abandonar a própria qualificação profissional é acabar com perspectivas de inserção no mercado de trabalho ou ainda interromper o próprio crescimento profissional. Diagnosticar e combater a evasão são ações que requerem a participação de todos os agentes escolares. Tendo em vista esse pressuposto, o objetivo deste trabalho consistiu na elaboração, por meio do Projeto Político Pedagógico, de ferramentas auxiliadoras que possam estimular a permanência dos alunos em uma instituição que promove cursos de capacitação profissional. Por intermédio de revisões bibliográficas e de aplicação de questionários com alunos que solicitaram o cancelamento de sua matrícula, bem como com docentes, coordenação e supervisão escolar, foi possível estabelecer alguns dos fatores preponderantes que estão relacionados à evasão escolar da instituição de ensino foco da pesquisa. Os resultados indicam que aproximadamente 50% dos alunos que se matriculam no ensino profissional realizaram o cancelamento de sua matrícula, justificado por dois tipos de fatores, internos e externos à escola, mas que em ambos os motivos se constatou que o colégio pode contribuir na promoção de meios que efetivem a profissionalização e conclusão do aluno no curso escolhido. O estreitamento de relações entre educandos e agentes escolares, priorizando o diálogo e estabelecendo estruturas favoráveis a permanência do aluno, é um dos conceitos básicos do Projeto Político Pedagógico, que elaborado coletivamente, resulta em uma escola colaborativa e acessível à comunidade, diminuindo assim a evasão dos alunos.

Published: March 2019

Toxoplasma gondii is an obligate intracellular protozoan parasite, recognized as the etiologic agent of toxoplasmosis, a zoonotic endemic disease in several countries, including Mexico. In the Yucatan State of Mexico, Toxoplasma infection has a high impact in both human and domestic animal health. Wild animals can also host zoonotic pathogens such as Toxoplasma gondii. The presence of Toxoplasma gondii DNA in roadkill wild animals in Yucatan was detected using a nested Polymerase Chain Reaction. Toxoplasma gondii DNA was identified in several organs retrieved from a Yucatan squirrel (Sciurus yucatanensis), a coatimundi (Nasua narica), and a greater grison (Galictis vittata). The amplified fragments of Toxoplasma gondii DNA were purified, sequenced, and certified by BLAST analysis. Our results confirm that Toxoplasma gondii can infect wild mammals from Yucatan, which could act as intermediate hosts and contribute to the transmission of the disease to humans and domestic animals, as well as other wild animal species. We present the first molecular evidence of Toxoplasma gondii in a squirrel and a coatimundi from Yucatan, and quite possibly in a greater grison at a global level.Figure 1. Agarose gel presenting PCR amplicons (560 bp) positive to Toxoplasma gondii. 1) C+: positive control; A: Yucatan squirrel liver sample; B: great grison femoral muscle sample; C: coatimundi kidney sample; C-: negative control. 2) A: Yucatan squirrel brain sample; B: great grison lung sample; C-: negative control.

We explored the predictive effect of goal-oriented learning strategies on Chinese adult students' academic performance in distance learning, using self-regulated learning as the underpinning theory. The relationship was analyzed using structural equation modeling, and the results indicated
that self-regulation strategies and goal orientation were positively related to academic achievement. We also found a significant and positive indirect relationship of mastery goal orientation and academic performance through self-regulated learning strategies. Further, the performance-approach
goal orientation had a positive indirect influence on academic performance, with the effort-regulation strategy fully mediating this relationship. The theoretical and practical implications of these findings are discussed.

Doxorubicin is an anthracycline drug which is believed to cause immediate damage to myocardial cells by free radical generation in the cause of treatment of cancer. This study was however aimed to investigate the effects of the aqueous extract of the seedlings of Vigna unguiculata on heart, kidney as well as lipid profile disorders caused by this drug on female Wistar albino rats. Fifteen female Wistar albino rats were divided into three groups. Group 1 animals served as normal positive control; Group 2 animals served as negative control which were treated with 0.5mL of (20mg/kg body weight doxorubicin) while Group 3 animals were treated with 0.5mL each of 20mg/kg body weight doxorubicin and 10% aqueous extract of seedlings of Vigna unguiculata. Some enzyme markers and lipid contents were determined. The results of the study showed an increase in the activities of plasma ALP and AST after treatment with the drug except in the heart for AST which showed a significant reduction, while treatment with the extract brought about a decrease in the plasma and the organs except for kidney AST. The ALT on the other hand showed slight increase in the plasma with a decrease in the kidney and heart after treatment with the drug as the treatment with the extract tend to restore it to the control in both cases, there was increased plasma and kidney but reduced heart HDL-C after treatment with the drug which was observed to be restored to control after treatment with extract in both situations. The triglyceride and total cholesterol did not show similar trend in the plasma and the studied organs. The LDL-C was also observed to be increased in both plasma and organs after the treatment with the drug which later reduced significantly towards the control after the administration of the sprout extract. The present study has shown that the doxorubicin has damaging effects on both kidney and heart tissues while the sprouts extract produce a restoration to the normal in both organs.

This study was an attempt to delineate the effect of allethrin based mosquito coil exposure on male fertility of wistar albino rats. This also includes two months of discontinuation of exposure to know whether there is any reversibility of changes. We also studied the role of an antioxidant (Vitamin C) in ameliorating the effect caused by the coil.The animals in our study were randomized into four groups: group I served as control rats; group II, III and IV received mosquito coil smoke 8 hours a day, 7 days a week for 12 week. Group IV rats co-administered oral supplementation of Vit. C (20 mg/kg body weight) once in a day for the same time period while group III animals were further kept for 8 weeks without any exposure to demonstrate withdrawal effect. Mean testicular weight was maximum in Group IV(1.83±0.30 gm) followed by group I(1.56±0.19gms), group III(1.22±0.42 gms) and group II(0.64±0.09 gm). Mean sperm count ranged from 83.75±9.61 units in Group II to 100.0±16.68 units in Group III, 130.7±14.14 units in Group IV and 157.7±7.92 units (Group I). Mean % abnormal sperm morphology was maximum in Group II (36.95±7.87%) followed by Group III (30.66±9.59%), Group IV (11.97±2.74%) and Group I (5.37±1.28%). Statistically, this difference was significant (p<0.001). This study demonstrates different types of abnormal sperm morphology. This study has its own merit that it also depicts the possible improvement after discontinuation of exposure and vitamin C supplementation.
Comparing The Principalship of Madrasah and Sekolah in The Decentralization Era
Authors: Safi'i Saefudin A
Published: March 2019

The downfall of the New Order Regime in 1998 brought about significant change to Indonesia’s public sector.  Law number 22 of 1999, further refined by Law 32 of 2004, provide legal bases for district governments to administer the public sector. The central government also introduces the notion of good governance through the promulgation of various regulations. For Madrasah however, decentralization policy failed to provide clear legal bases as to how it relates to district government. Law 32 of 2004 verse 10 article 3 retains the centralized management by the Ministry of Religious Affairs. This however does not exclude Madrasah from public demand of implementing the principle of good governance. This study analyses the dynamics of principal-ship both in the Sekolah and the Madrasah in the era of decentralization. By comparing two research sites, this study sought to create better understanding about the context by which the organization climate of two different schools are shaped, and how principals and teachers perceives the notion of school leadership in the light of most recent policy development. To do this, interviews were undertaken and questionnaire-based data collection was also conducted. The study found that in the ground level implementation of decentralization policy, Sekolah developed more rigorous leadership compared to that in the Madrasah. This research recommends the adoption of stronger regulation regarding principal-ship of Madrasahs in order to create an environment that is more in tune with the spirit of public service reforms.
