¿Es la práctica pedagógica una práctica sexual? Umbrales de la imaginación teórica y erótica
Authors: Flores Val
Published: March 2019

Una lectura aberrante desde una posición feminista prosexo y un pensamiento pedagógico dis/torsionado por una interpelación que resulta intolerable para el régimen de inteligibilidad de la normalidad educativa, la pregunta ¿es la práctica pedagógica una práctica sexual?, casi de tono absurdo e inadmisible, opera aquí como radical extrañamiento en los constructos y órdenes conceptuales de las sexualidades y en nuestros imaginarios pedagógicos y eróticos. En este ensayo se propone, a partir de tres experiencias de taller de formación, problematizar la fuerza heterosexualizante de la cultura escolar y considerar la potencia erótica de los procesos de producción del conocimiento.

The effects of surface acting toward supervisor on employee burnout
Authors: Hwang Sunkyung , Lee Hyejeen , Park HyungIn
Published: March 2019

The current study examined the effect of supervisor’s neuroticism on employee’s job burnout, and the moderating effects of neuroticism of the supervisor and the employee on the relationships between surface acting toward supervisor and employee burnout. Data were collected from 448 full-time workers who had a supervisor. Regression analyses showed that supervisor’s neuroticism was positively related to employee burnout in the cynicism facet; however, additional polynomial regressions revealed that supervisor’s neuroticism was related to all three facets of employee burnout when the level of supervisor’s neuroticism was consistent with that of employee’s. Contrary to the hypothesis, employee’s neuroticism had a buffering effect on the relationship between employee’s surface acting and professional inefficacy. Finally, the three-way interaction among surface acting, supervisor’s neuroticism, and employee’s neuroticism was significant for exhaustion. Specifically, when supervisor’s neuroticism was high and employee’s neuroticism was low, surface acting on exhaustion increased the most. Based on these findings, implications of this study and directions for future research were discussed.
Relationship between role stress and employee silence behavior
Authors: Jung SoYeon , Yoo TaeYong
Published: March 2019

The purpose of this study was to investigate the influence of role stress(role conflict, role ambiguity, and role overload) on employee silence behavior and the mediating effect of psychological ownership between two variables. In addition, this study examined the moderating effect of perceived supervisor support on the relationship between psychological ownership and employee silence behavior. Using the survey research method, data were collected from 310 employees who were working in a variety of organizations in Korea. As results, role conflict, role ambiguity, and role overload had positive relationships with employee silence behavior. And psychological ownership had mediation effect in the relationship between role conflict/role ambiguity and employee silence behavior. The perceived supervisor support had moderation effect on the relationship between psychological ownership and employee silence behavior. That is, the negative relationship between psychological ownership and employee silence behavior was stronger when the perceived supervisor support was high rather than low. Finally, based on these results, we discussed the implications and limitations of the study, and the suggestions for the future research.
Unstructured data analysis and visualization “Korean Journal of Industrial and Organizational Psychology(2010～2017)”
Authors: Yi Insun , Na Eunyoung
Published: March 2019

With the spread of Big data, there is an increasing interest in Unstructured Data analysis techniques, and studies are being carried out to extract valuable information from vast amounts of academic data. Most passive analysis of large texts by humans is time consuming and laborious and difficult, so a technique that can automatically classify them in order to supplement them is needed. Therefore, this study analyzed and visualized by using Unstructured Data such as the main words, thesis title, and abstract of ‘Korean Journal of Industrial and Organizational Psychology’ published from 2010 to 2017. The results of the study are as follows. First, ‘organizational commitment’ was frequently used as a result of visualization of the key words using wordcloud. Job satisfaction, job enthusiasm, turnover intention, emotional labor showed the order. Second, the title of the paper and the abstract were automatically classified into 10 topics based on the LDA probability. Topic 8(organization/commitment/perception) was the highest, and Topic 5(behavior/management/boss) was the lowest. Third, the relationship between the main author and the correspondent author appeared as six large groups and several small groups. We were able to identify influential authors within the group. In this study, it is suggested that related researchers can get access to another research by deriving information from a vast amount of academic data more quickly and easily.
The relationship between social dominance orientation and contextual performance
Authors: Lee HyunJun , Yoo TaeYong
Published: March 2019

The purposes of this study were, first, to confirm the internal structure of social dominance orientation by using Korean working adult sample. Second is to investigate the effect of social dominance orientation on the employee’s contextual performance at the facet level, along with exploring the possible role of narcissistic self-concept(grandiosity) and interpersonal motive(dominance). Using the survey research method, data were collected from 411 employees who were working in a variety of organizations in Korea. The results of study showed that subdimensions of social dominance orientation(SDO-D, SDO-E) were significantly correlated with each other and SDO-E factor was negatively related with interpersonal facilitation. SDO-D factor was not significantly related with neither interpersonal facilitation nor job dedication. However, grandiosity and dominance fully mediated the relationship between SDO-D factor and both subdimensions of contextual performance. Based on these results, we discussed the implications of study, limitations, and the suggestions for future research.

Authors: . Ratnah
Published: March 2019

Recently, the development of tourism  is increasing sharply and hotel industry has important role to support the tourism development in terms of providing the comfortable accommodation and excellent services and English language competencies should be possessed by the hotel employees in order to provide excellent services. However, some hotel employees still have low competence in English language skill. The purpose of this study is to find out the language skills that are mostly needed and categorized as the problems by the hotel employees in their work. This study employed quantitative study by using questionnaire and interview as the method of data collection.  The sample of this study was taken by using purposive sampling by taking 30 tourism students who have just completed their six-month internship program in the industry. Based on the results of data analysis, it has been found that most language skills (listening, speaking, and writing) are categorized “High”   used by the hotel employees, as their score between 3.41-4.20. While reading skills are categorized “Moderate” as its mean score between 2.61-3.40. And also All the language skills (listening, speaking, reading, and writing) are categorized “High” as problems faced by the hotel employees, as their score between 3.41-4.20.

Authors: Pilton Joanna L. , Chau Jennifer , Foo Timothy S. , Hall Evelyn J. , Martinez-Taboada Fernando , Podadera Juan M. , Makara Mariano A.
Published: March 2019

OBJECTIVE

To evaluate 3 doses of gadoxetic acid (Gd-EOB-DPTA) for hepatic CT and cholangiography in cats and to determine optimal timing for hepatobiliary image acquisition and evaluation of the contrast-enhanced hepatobiliary anatomy.

ANIMALS

6 healthy cats.

PROCEDURES

Cats were anesthetized; sequential CT scans were performed 0, 5, 25, 45, 65, and 85 minutes after IV administration of Gd-EOB-DTPA at low (0.0125 mmol/kg), medium (0.1 mmol/kg), and high (0.3 mmol/kg) doses. Hepatobiliary enhancement for each dose was objectively assessed over time and by use of a subjective semiquantitative visual assessment score.

RESULTS

No contrast-related adverse effects were detected. Each increase in dose of contrast medium resulted in a significant increase in HU across the hepatobiliary system. The liver had a significantly higher number of HU at 45 minutes, with homogenous enhancement at all doses of contrast medium. Contrast-enhanced cystic and bile duct HU were significantly higher and maximal at 65 minutes. Contrast-enhanced gallbladder HU did not plateau by 85 minutes. At a high dose of contrast medium, 12 of 60 (20%) biliary tract scores indicated no enhancement, 34 (57%) indicated poor enhancement, and 14 (23%) indicated moderate enhancement. No cat had excellent enhancement of the biliary tract at any dose.

CONCLUSIONS AND CLINICAL RELEVANCE

Gd-EOB-DTPA–enhanced hepatic CT and cholangiography in cats were safely performed and provided good hepatic enhancement but poor to moderate enhancement of the biliary tract. This technique may be useful for assessing the liver parenchyma in cats, but its value for assessing the biliary tract is questionable.
Predictive values of serum uric acid and Alanine-aminotransferase for fatty liver index in Montenegrin population
Authors: Klisic Aleksandra , Kavaric Nebojsa , Ninic Ana
Published: March 2019

Background

Alanine-aminotransferase (ALT) and uric acid cut-off levels used in non-alcoholic fatty liver disease (NAFLD) diagnosis are advised to be lowered. Due to contradictory results on the utility of both these biomarkers for NAFLD screening, we aimed to determine their cut-off levels that can be applied to Montenegrin population with the fatty liver disease.

Methods

A total of 771 volunteers were enrolled. A fatty liver index (FLI) score ≥60 was used as proxy of NAFLD. The receiver operating characteristic curve analysis with the area under the curve (AUC) was used to determine the cut-off values of ALT and uric acid associated with FLI ≥60.

Results

ALT was independent predictor of FLI in both men and women, whereas serum uric acid was its independent predictor only in women. Lower cut-off levels of ALT are associated with the increased prevalence of NAFLD [i.e., ALT was 19 IU/L (AUC=0.746, sensitivity 63%, specificity 72%, P<0.001) in women and 22 IU/L (AUC=0.804, sensitivity 61%, specificity 95%, P<0.001) in men]. The cut-off value for uric acid was 274 μmol/L (AUC=0.821, sensitivity 68%, specificity 82%, P<0.001) in women.

Conclusions

Lower cut-off levels of ALT in both genders, and serum uric acid in females, can be reliable predictors of the FLI.

Authors: Juhas Irina , Skof Branko , Popović Dejana , Matić Milan , Janković Nenad
Published: March 2019

Background

Increased lipid levels are one of the major risk factors for the development of cardiovascular diseases. The aim of the current study was to evaluate the effect of short-term (8 weeks) aerobic exercise of moderate to vigorous intensity on lipid profile in young healthy females.

Methods

27 female students (mean age 20.5 ± 1 year) completed 8 weeks of aerobic training that included two exercise sessions of continuous aerobic activity of moderate intensity (running 35–60 min) and one exercise session with interval training of vigorous intensity. Intervention aerobic capacity and lipid profile were examined before and after the exercise.

Results

Exercise intervention has caused a decrease of low density lipoprotein levels per 9.8% (from 2.52 ± 0.47 to 2.27 ± 0.53 mmol/L; p < 0.001) and significant improvement of high density lipoprotein (HDL) levels per 22.7% (from 1.29 ± 0.24 to 1.59 ± 0.24 mmol/L; p < 0.001), total cholesterol/HDL ratio per 17.2 % and aerobic capacity (VO2 max) per 3.8 % (43.9 ± 3.7 to 45.56 ± 3.63 mLO2/kg/min).

Conclusions

The results support the hypothesis that a short-term aerobic exercise intervention of moderate to vigorous intensity may have significant effects on blood lipid profile in young healthy females.
Diagnostic benefits of mindin as a prostate cancer biomarker
Authors: Hanousková Lenka , Řezáč Jakub , Veselý Štĕpán , Průša Richard , Kotaška Karel
Published: March 2019

Background

It has been shown that decreased expression and activity of extracellular matrix protein mindin correlate with various types of cancers including breast, colon and lung cancers. The aim of the presented study was to investigate the serum mindin levels in prostate cancer.

Methods

Mindin concentrations in serum were measured in 56 patients with prostate cancer (mean age 68 years) and in control group of 29 healthy men (mean age 64 years) using commercially available enzymatic immunoassay (Cusabio, WuHan, China). The patients were divided with respect to the severity of the disease into two groups according to the EAU guidelines (stage 1, 2 – less severe tumours, stage 3, 4 – severe tumours).

Results

Serum mindin concentrations were significantly elevated in the group of healthy individuals unlike in the patients with prostate cancer (2.12 ng/mL vs 0.78 ng/mL, with P=0.0007, AUC=0.705). Patients with less severe tumours (stage 1, 2) and severe tumours (stage 3, 4) had significantly decreased levels of S-mindin as well (P=0.0037), although the difference in serum mindin concentrations between the patients with less severe and severe tumours was not significant.

Conclusions

Concentrations of mindin were decreased in patients with prostate cancer and reduced in patients with less severe prostate cancer as well. Mindin appears to be a promising diagnostic marker useful in the diagnosis of prostate cancer.

Published: March 2019

Background

The objective of this work was to study the profile of fatty acids and to search for associations of fatty acids with oxidative-antioxidant parameters and an oxidative-inflammatory biomarker (lipoprotein-associated phospholipase A2) in men with coronary atherosclerosis and coronary heart disease.

Methods

Analysis of 20 fatty acids was performed in 60 men with angiographically confirmed coronary atherosclerosis and coronary heart disease and in a control group of men without coronary heart disease. Serum fatty-acid content was evaluated by high-performance gas-liquid chromatography. The blood levels of oxidative stress, total antioxidative defence, and lipoprotein-associated phospholipase 2 were analyzed.

Results

In the group of men with coronary atherosclerosis the levels of myristic and palmitic fatty acids were higher by 59% and 22%, respectively. An increase in the weight percentage of monounsaturated fatty acids was noted, such as palmitoleic, oleic, and octadecenic. Significantly lower levels of polyunsaturated fatty acids, such as linolic, eicosadienoic, eicosatrienoic, arachidonic, eicosapentaenoic, γ-linolenic, docosapentaenoic, and docosahexaenoic were detected in the group with coronary atherosclerosis. The lipoprotein-associated phospholipase A2 level was higher by 48%. Oxidative stress was higher by 17%, and the total antioxidant defence in serum was lower by 45%. We found correlations between fatty acids and oxidative-antioxidative alterations. The relative risk of vulnerable atherosclerotic plaques correlated with increased levels of palmitic, stearic, oleic, and linolic fatty acids.

Conclusions

Significant alterations in the profile of fatty acids are associated with oxidative-antioxidative alterations and are accompanied by an increase in free-radical formation, which can probably serve as a risk factor of atherosclerosis.
Characteristics of selected active substances used in disinfectants and their virucidal activity against ASFV
Authors: Juszkiewicz Małgorzata , Walczak Marek , Woźniakowski Grzegorz
Published: March 2019

African swine fever (ASF), caused by African swine fever virus (ASFV), is currently one of the most important and serious diseases of pigs, mainly due to the enormous sanitary and socio-economic consequences. It leads to serious economic losses, not only because of the near 100% mortality rate, but also through the prohibitions of pork exports it triggers. Currently neither vaccines nor safe and effective chemotherapeutic agents are available against ASFV. The disease is controlled by culling infected pigs and maintaining high biosecurity standards, which principally relies on disinfection. Some countries have approved and/or authorised a list of biocides effective against this virus. This article is focused on the characteristics of chemical substances present in the most popular disinfectants of potential use against ASFV. Despite some of them being approved and tested, it seems necessary to perform tests directly on ASFV to ensure maximum effectiveness of the disinfectants in preventing the spread of ASF in the future.
Genetic diversity of Campylobacter jejuni isolated from the poultry food chain
Authors: Wieczorek Kinga , Osek Jacek
Published: March 2019

Introduction:
Campylobacter jejuni is one of the most frequently reported causes of foodborne bacterial enteric disease worldwide. The main source of these microorganisms is contaminated food, especially of poultry origin. There are several molecular methods for differentiation of Campylobacter isolates at the subgenus level, and one of these is porA-typing based on the sequencing of the major outer-membrane protein (MOMP) encoding gene. The aim of the study was to test the molecular relationship of C. jejuni strains isolated at different points along the poultry food chain and assess the population structure of the isolates.

Material and Methods: A total of 451 C. jejuni were used in the study, and a DNA fragment of 630 bp of the MOMP encoding gene was amplified and sequenced.

Results: One hundred and ten sequence types were identified, with 69 (62.7%) unique to the isolates' origin and 30 not present in the database. The most prevalent nucleotide variant 1 was detected in 37 (8.2%) strains. These isolates were identified in all poultry sources tested, especially in faeces (15 isolates) but also in poultry carcasses and meat (11 isolates in each).

Conclusion: The porA typing method was highly discriminative for C. jejuni of poultry origin since the Simpson's diversity index (D) achieved a value of 0.876, indicating considerable diversity in the bacterial population tested. The method may be further used for epidemiological investigation purposes.

Introduction: Pacemaker implantation is the only effective symptomatic treatment for life-threatening bradyarrhythmias. Major complications observed after implantation of cardiac pacemakers include lead dislocation, loss of pulse generator function, and inadequate stimulation. The aim of this retrospective single-centre study was to analyse the indications for pacemaker implantation and the incidence and types of complications associated with this procedure in dogs treated for symptomatic bradyarrhythmia.

Material and Methods: The retrospective analysis included 31 dogs with symptomatic bradyarrhythmia, implanted with permanent cardiac pacemakers in 1992–2017. The list of analysed variables included patient age, breed, sex, indication for pacemaker implantation, comorbidities, and the incidence of procedure-related complications along with the type thereof.

Results: The most common indication for pacemaker implantation was 3rd degree AVB, followed by SSS, advanced 2nd degree AVB, and PAS. Pacemaker implantation was associated with a 35% overall complication rate and 6.45% periprocedural mortality. There were no significant differences in terms of procedure-related complications with regard to age, sex, breed, indications for pacemaker implantation, or comorbidities.

Conclusions: Cardiac pacing is the only effective treatment of symptomatic bradycardia, but as an invasive procedure, may pose a risk of various complications, including death.
The introduction of accrual accounting and budgeting in the city state of Hamburg: A qualitative analysis of the reform process and its benefits
Authors: Wagner-Krechlok Kristin , Hilgers Dennis , C. Brixner Helge
Published: March 2019

In a multiple-step reform process, the city-state of Hamburg introduced a full accruals accounting and budgeting system. Based on a document analysis, this paper describes how the reforms were implemented, who the supporters were, and what the motivation behind their support was. It also analyses what benefits users of financial information have gained from the reforms by using responses resulting from semi-structured interviews. The authors find that the main actors were the state parliament and the state government, whose primary aim was to increase transparency about public resources and their consumption. These actors benefitted from the reforms because they now have information available that enables them to fulfil their respective roles within the budget process, and to achieve their political objectives. The authors conclude that under these conditions information use is encouraged and, thus, contribute to a better understanding of how reforms in public sector financial management succeed.
A escravidão contemporânea no Brasil, seus “nomes” e a lista suja: (im)pactos e retrocessos
Authors: Guimarães Anne Gabriele Alves , D’Angelo Isabele Bandeira de Moraes
Published: March 2019

O presente estudo busca analisar o trabalho em condições análogas às de escravo, realizando um contraponto ao conceito de “trabalho decente” estabelecido pelas legislações trabalhistas internacionais. Dentro do contexto neoliberalista global e do processo capitalista produtivo, há a proposta de se investigar um instrumento no combate à escravidão contemporânea: a lista suja. Apesar das polêmicas em torno dela, acredita-se ser a mesma um meio eficaz para coibir práticas degradantes das capacidades laborais e da dignidade humana por exercer forte pressão sobre o mercado. A divulgação da lista suja acaba sendo antagônica às pretensões da elite empresarial, pois faz refletir sobre os sujeitos reprodutores de relações sociais dominantes, a saber, Estado, grandes corporações e mercado. Utiliza-se metodologia com viés exploratório e descritivo.

The article describes the process of developing a technology for producing nanoparticles based on a copolymer of lactic and glycolic acids (PLGA) containing dipropoxybacteriopurpurinimide (DPBPI) for photodynamic therapy of malignant tumors of various origins. Technological parameters for optimizing the method in order to obtain nanoparticles with specified characteristics are presented in this paper. As a result, the nanoparticles sample with an average particle diameter of 222.6±2.8 nm; ξ-potential 26.3±4.61 mV; polydispersity index 0.144; the total content of DPBPI in PLGA-DPBPI nanoparticles 13.6% were obtained. In accordance with the developed technique, the batch of PLGA-DPBPI nanoparticles was developed for further biological studies. In vitro experiments on A549 human non-small cell lung carcinoma for DPBPI, delivered as a part of PLGA-DPBPI nanoparticles, and an EL cremophor-based emulsion (CrEL-DPBPI) showed a similar intracellular distribution (concentrated in vesicular cell structures and diffusely distributed in cytoplasm), as well as high photo induced activity and the absence of dark cytotoxicity in case of PLGA-DPBPI nanoparticles. The study of the PLGA-DPBPI nanoparticles specific activity in vivo on the S37 mouse soft tissue sarcoma model showed the selective accumulation of DPBPI in tumor tissue and the almost complete elimination of DPBPI from the body within 48 hours, as well as significant antitumor efficacy in PDT.

Published: March 2019

The objectives of the study were to assess folate deficiency in patients with classic galactosemia, and to determine whether folic acid supplementation has an effect on galactose-1-phosphate uridyltransferase enzyme activity. Sixty-one newborn infants diagnosed with classic galactosemia between 2010 and 2017 were retrospectively evaluated. Within this group, 48 patients with Q188R homozygous mutation alone were enrolled into the study. Serum folate concentration was studied using chemiluminescence; and in folate deficient patients, galactose-1-phosphate uridyltransferase measurements before and after folic acid supplementation (100 mg/day folic acid for 30 days) were performed using an enzymatic calorimetric measurement technique based on kinetics. The serum folate level was low ( < 4 ng/ml) in 12 patients (25%). The galactose-1-phosphate uridyltransferase enzyme activity after folic acid supplementation was significantly higher than the values before folic acid supplementation (1.00±0.19 U/g Hb vs. 0.74±0.23 U/g Hb, p < 0.05); but was still less than the normal levels. Folate deficiency, most likely due to poor dietary intake, may develop in pediatric patients with classical galactosemia, and folic acid should be supplemented. Folic acid supplementation appears to have a low, but statistically significant, effect on galactose-1-phosphate uridyltransferase enzyme activity, but comprehensive research is needed to clarify whether there is any clinical significance.

Published: March 2019

Henoch Schönlein purpura (HSP) with acute rheumatic fever (ARF) is a rare entity and only few cases have been reported so far. In all previously reported cases with HSP and ARF, patients initially presented with purpuric rash, arthralgia/arthritis, or abdominal pain and later diagnosed as ARF. We report an 11-year-old girl with features of both ARF and HSP. She initially presented with arthralgia and murmur. Echocardiography showed mild to moderate mitral regurgitation. Later, the clinical course was complicated by purpuric rash and abdominal pain. She was treated conservatively with IM penicillin, acetylsalicylic acid and oral prednisolone. Our patient is the first patient with HSP and ARF who initially presented with features of ARF. A review of literature revealed a limited number of cases of HSP associated with ARF (14 cases including the present case); and that the response to treatment in cases suffering from ARF associated with HSP was good; but one should also be aware of serious cardiac complications in HSP patients which may be fatal.

Kacang bogor merupakan tanaman kacang-kacangan yang memiliki kandungan karbohidrat, protein, dan lemak yang cukup baik. Pengolahan yang dilakukan dengan baik dapat mempertahankan kandungan nutrisi dengan baik. Sebagian besar masyrakat mengkonsumsi kacang bogor dengan cara direbus atau sebagai campuran sayur. Salah satu cara pengolahan kacang bogor agar kandungan nutrisinya tidak banyak terbuang yaitu dengan proses pengeringan. Kacang bogor kering yang ditepungkan memiliki kandungan kalori yang lebih tinggi dibandingkan dengan kacang bogor rebus. Akan tetapi, pengolahan tepung kacang bogor memiliki kendala, salah satunya adalah lama pengeringan. Pengeringan kacang bogor dilakukan dengan menggunakan oven gelombang mikro agar waktu pengeringan lebih efektif. Penelitian ini bertujuan untuk mengetahui pengaruh proses blansing dan daya oven gelombang mikro terhadap karakteristik tepung kacang bogor yang dihasilkan. Metode rancangan lingkungan yang dipilih adalah rancangan acak lengkap (RAL) yang terdiri dari dua faktor yaitu faktor perlakukan pendahuluan (a) yang terdiri dari 2 level yakni: tanpa blansing dan dengan blansing dan faktor daya pengeringan oven gelombang mikro (b) yang terdiri dari tiga level, yakni: 50%, 70%, dan 100% dengan empat kali ulangan. Hasil penelitian menunjukkan bahwa kombinasi perlakuan blansing dan daya pengeringan oven gelombang mikro 50% selama 30 menit merupakan perlakukan terbaik.

The synthesis of zeolite materials by hydrothermal transformation of kaolin using an alkaline fusion prior to hydrothermal synthesis method was investigated. The kaolin clay used in the present investigation was supplied from Iraq. The physical and chemical characterization of  the  starting kaolin and produced zeolite Na-LSX samples were carried  out  using  different analytical techniques such as Scanning Electron Microscopy (SEM), Energy Dispersive Spectroscopy (EDS), X – Ray Diffraction (XRD), X – Ray Fluorescence (XRF), Thermogravimetric Analysis (TGA), Fourier Transform Infrared (FT-IR) Spectroscopy and Inductively Coupled Plasma-Optical Emission Spectrometer (ICP-OES). An alkaline fusion method was introduced prior to the hydrothermal treatment while kaolin clay powder was mixed manually with NaOH powder (ratio = 1/1.2 in weight). The metakaolinisation phase was achieved by calcining the mixture in air at 600 oC for 1hr. The result from this route shows that zeolite Na-LSX with cubic rounded edge crystal habit have been successfully synthesised. Finally, The kinetic study indicated the suitability of the zeolite Na-LSX for the removal of Cu2+, Fe3+, Pb2+ and Zn2+ ions from synthetic wastewater.

Published: March 2019

Deproteinised leaf extracts previously found favourably enhancing plant and fungi growth. Present attempt has been made to observe its influence in enhancing the enzyme nitrate reductase. Crop of Eleusine coracana was cultivated  and  treated  by  deproteined  whey  from  the  leguminous  weed Cassia tora  and  its  influence examined on the  activity of  the  enzyme  nitrate  reductase  by  spectrophotometric method. Cassia tora  crop  was fractionated  for  the  purpose  to  isolate  crude  leaf  protein by  heating the juice  to  90°C  which gave  deproteinised  leaf  juice (DPJ). The crop growth was also compared with other monocotyledonous wheat,  Sorghum and  bajra   crops.  There  was  enhancement of nitrate  reductase  in  wheat  crop  by the application of  non  leguminous  Basella forage DPJ. There  was  lesser  activity  of  nitrate  reductase in  Eleusine  crop  by the influence  of Cassia  tora  DPJ probably because  of  the  deficiency  of  element  molybdenum in  the utilised  red  soil  for  the   growth  of  crops or allelopathy. Length  and  number  of  leaves of  Eleusine crop was  measured.

Authors: Kidirali Karimbayev
Published: March 2019

Background: Perinephric abscess and renal replacement lipomatosis (RRL) as a late and rare complications of urolithiasis.Case presentation: We report the case of a 62-year-old Kazakh woman who suffered for a long period of time from back pain,weakness (has been treated with confirmed osteochondrodystrophy) and was not aware about her kidney stones. She hadnever had hematuria or renal colic and urgently was admitted in a serious condition with large palpable abdominal mass. Thediagnostic workup, differential diagnosis, surgical management, medical follow-up and a review of the literature presented.Persistent back pain and weakness for several years were caused by nephrolithiasis and its late and rare complications likeRRL. Only one of the acute complications of nephrolithiasis as perinephric abscess attracted the attention of urologists andmade it possible to set up the correct diagnosis. Surgical management of the hephrolithiasis complications (urgent drainage ofperinephric abscess and delayed nephrectomy [because nonfunctioning kidney with multiple stones as a nidus of infectionsand RRL] after stabilization of patient’s condition was performed.Conclusion: Occasionally urolithiasis may mimic signs of spine disease, so in patients with persistent back pain which did notrespond to conventional therapy of this pathology should be excluded the hephrolithiasis. Non-treated urolithiasis may lead toloss of the kidney function and development of life-threatening acute complications like perinephric abscess and later – renalreplacement lipomatosis.

Published: March 2019

The present study aimed to evaluate the effects of applying fungicides with different sources of copper and of the number of applications on the occurrence of Leucoptera coffeella (Guérin-Menéville & Perrottet, 1842) (Lepidoptera: Lyonetiidae) and on the wax layer on leaves in a coffee plantation. Four applications of fungicides were carried out and the effects on the number of leaves mined by the insect and on the wax content on the leaf surface were evaluated. The copper-based fungicides increased the number of leaves mined by the leaf-miner and reduced the wax content on the coffee leaf surfaces in both periods studied.

Coffee cultivars that are better adapted and more productive can help reduce production costs and make coffee cultivation more profitable. The Mundo Novo cultivar has stood out as one of the most productive cultivars of Coffea arabica L. Therefore, the aim of this work was to select Mundo Novo progenies with high bean yield capacity and with other agronomic characteristics of interest. We evaluated the bean yield, seed size, plant height, upper and lower canopy diameter, stem diameter, and plant vigor of 24 F4 progenies and one check cultivar. The experimental design consisted of a randomized complete block design with three replications and experiments were carried out in two sites: São Sebastião do Paraíso (SSP) and Três Pontas (TP), MG, Brazil. The mixed model approach was used to calculate the genotypic value for each progeny, after which the selective accuracy and genetic gain of the two best progenies in each trait were calculated. To summarize, the simultaneous selection index of Mulamba and Mock was used to select the two most promising progenies at each site. In general, the genetic gain was higher at SSP than at TP. In SSP, the most promising progenies were 1 [IAC376-2 (M. Novo) x IAC386-17 (M. Novo)] and 20 [IAC382-10 (M. Novo) x IAC388-20 (M. Novo)]. In TP, the most promising progeny was 22 [H1535/181 (M. Novo) x (S795) 1344/10/5], together with the check (Mundo Novo IAC379/19). The highest selection gain was expressed for bean size (the percentage of beans retained in sieve 17).

Authors: ÖKSÜZ Hazal , ATILGAN Esra
Published: March 2019

Amaç:
Kronik boyun ağrısı olan bireylerde klasik fizyoterapi programı ve buna ek
olarak uygulanan Elektromyografi Biofeedback ile gevşeme eğitiminin; ağrı, kas
aktivasyon düzeyi, aktivite limitasyonu ve depresyon düzeyleri üzerindeki
etkisini kıyaslamaktır. Yöntem: Çalışmada Grup 1’e (n=20, 17 kadın,3
erkek,  yaş ortalaması= 44,85 ±12,51)
klasik fizyoterapiye (Transkutanöz Elektrik Sinir Stimulasyonu, ultrason,
hotpack ve ev egzersizi) ek olarak Elektromyografi Biofeedback ile gevşeme
eğitimi, Grup 2’ye (n=20, 15 kadın, 5 erkek, 
yaş ortalaması=43,84±12,33) ise sadece klasik fizyoterapi programı
uygulandı. Tedavi haftada beş gün, dört hafta yapıldı. Bireylere tedavi öncesi ve
sonrasında Vizüel Analog Skala, gonyometrik ölçümler (fleksiyon, ekstansiyon,
sağa ve sola lateral fleksiyon ve rotasyonlar), yüzeyel Elektromyografi
Biofeedback, Boyun Özürlülük Sorgulama Anketi ve Beck Depresyon Ölçeği
uygulandı. Sonuçlar: Tedavi sonrasında her iki grupta ağrının azaldığı ve tüm
yönlerde eklem hareket açıklığının arttığı görüldü (p=0,00). Her iki grupta sol
üst trapez kasında kas aktivasyon düzeyinin azaldığı (p=0,005), birinci grupta
sadece sağ üst trapez kasında azalma olduğu görüldü (p=0,003). Özürlülük anketi
(p=0,012) ve Beck Depresyon (p=0,001) skorlarında azalma belirtildi. Tartışma:
Elde edilen sonuçlar, her iki grupta da gelişme olduğu görüldü. Ancak Grup 1’de
ağrı, eklem hareket açıklığı, aktivite limitasyonu ve depresyon düzeyinde ki
gelişmelerin daha fazla olduğuna işaret etmektedir. Burdan yola çıkarak,
Elektromyografi Biofeedback ile gevşeme eğitiminin kliniklerde klasik
fizyoterapi programına eklenmesi ile daha etkili tedavi sonuçlarının elde
edilebileceği görüşüne varılmıştır.
