Published: November 2017

Cobalt-doped ZnO thin films have been deposited using a sol–gel route by changing the number of coats on the substrate from 6 to 18. This project deals with various film thicknesses by increasing the number of deposited coats. The effect of thickness on structural, magnetic, surface morphology and optical properties of Co-doped ZnO thin film was studied. The crystal structure of the Co-doped ZnO films was investigated by X-ray diffraction. The films have polycrystalline wurtzite hexagonal structures. A Co2+ ion takes the place of a Zn2+ ion in the lattice without creating any distortion in its hexagonal wurtzite structure. An examination of the optical transmission spectra showed that the energy band gap of the Co-doped ZnO films increased from 3.87 to 3.97 eV with an increase in the number of coatings on the substrate. Ferromagnetic behaviour was confirmed by measurements using a vibrating sample magnetometer. The surface morphology of thin films was assessed by scanning electron microscope. The grain size on the surface of thin films increased with an increase in the number of coats.

Published: November 2017

Competitive activities always support improvement in quality. In this study, a repetitive group sampling plan is designed to compare the two process yield indices of respective suppliers. A ratio statistic of two yield indices is proposed for estimated linear profiles under normal assumptions. The operating characteristic function is derived by using the distribution of the ratio statistic. Designed parameters are optimized to minimize the sample size required.

Published: November 2017

Multi-wall carbon nanotubes (MWCNTs) modifications are introduced on the surface of prepreg to enhance the impact properties of epoxy/Kevlar fiber composites. First, six kinds of Kevlar fiber reinforced composite modified by different weight fractions of MWCNTs were prepared using the combination of spray and brush methods. Second, low-velocity impact experiments were carried out to study the dynamic behavior of neat and modified laminates in terms of the impact force, damage morphology, strain evolution, and impact energy. Finally, the results indicated that the MWCNTs modified laminates with weight fraction 1.67, 3.33 wt. % had superior dynamic responses than neat laminate, but much more MWCNTs content will decrease the impact properties of composite materials obviously. This work provided an important basis for designing and evaluating the nanometer modified laminates.

Authors: Galvão André Luiz Baptista , Carvalho Marileda Bonafim
Published: November 2017

A International Renal Interst Socity (IRIS) desenvolveu uma classificação para doença renal crônica (DRC) em cães. Pacientes com enfermidades que predispõem a DRC, sem alterações clínicas e laboratoriais, são considerados no estádio 0. No estádio 1, a creatinina sérica está inferior a 1,4 mg/dL, a poliúria e polidipsia podem estar presentes, bem como a incapacidade de concentrar urina. A creatinina sérica entre 1,4 mg/dL e 2,0 mg/dL, com manifestação clínica de poliúria e polidipsia, são características dos pacientes no estádio 2. No estádio 3, a creatinina sérica se comporta entre 2,1 mg/dL a 5,0 mg/dL, com manifestações clínicas moderadas da síndrome urêmica. No estádio 4, a creatinina sérica está superior a 5,0 mg/dL, com manifestações clínicas graves da síndrome urêmica. Objetivou-se com este trabalho estabelecer o estadiamento da DRC em cães clinicamente estáveis atendidos no Serviço de Nefrologia e Urologia do Hospital Veterinário “Governador Laudo Natel”, referente ao ano de 2013, seguindo critérios de classificação da IRIS. Dos 62 cães estudados, foram identificados 17 (27%) sadios e 45 (73%) com DRC, destes 45, foram identificados 12 (27%) em estádio 1, 10 (22%) em estádio 2, 13 (29%) em estádio 3, e 10 (22%) cães em estádio 4. Concluímos que a DRC em cães não apresenta predileção racial e/ou sexual, sendo os cães com idade superior a 7 anos os mais cometidos. A hipertensão arterial sistêmica e a proteinúria podem estar presentes em qualquer estádio da doença.

U radu je konstruiran Upitnik za ispitivanje stanja i potreba rada s darovitim i talentiranim učenicima. Upitnikom je ispitano stanje i potrebe rada s darovitim učenicima u osnovnim školama Republike Hrvatske između 378 učitelja razredne nastave i nastavnika predmetne nastave svih profila. Faktorskom analizom upitnika dobivena su tri faktora: 1) Posebni programi, metode i oblici rada s darovitim i talentiranim učenicima; 2) Skrb o darovitim i talentiranim učenicima; 3) Identifikacija i poticanje darovitih i talentiranih učenika. Zatim su ispitani rezultati na navedena tri faktora s obzirom na različite kategorije učitelja/nastavnika s obzirom na: a) tri različite regije Republike Hrvatske, b) različita profila, c) različitih godina staža i d) različita obrazovanja o darovitima. Rezultati istraživanja pokazuju da učitelji/nastavnici u osnovnim školama s obzirom na regiju Hrvatske statistički značajno više koriste posebne programe, metode i oblike rada u južnoj i srednjoj regiji Hrvatske u odnosu na sjevernu. U srednjoj i sjevernoj regiji Hrvatske u odnosu na južnu učitelji/nastavnici statistički značajno više skrbe o darovitim i talentiranim učenicima. Rezultati na faktoru identifikacije darovitih učenika najniži su među učiteljima/nastavnicima, što ne čudi jer je to prije svega posao stručnih suradnika, oni su statistički značajno veći u južnoj i srednjoj regiji Hrvatske u odnosu na sjevernu. Svi profili nastavnika s darovitim i talentiranim učenicima statistički značajno najviše rade posebne programe, metode i oblike rada, zatim neposredno skrbe o darovitima, a najmanje sudjeluju u identifikaciji darovitih i talentiranih učenika. Sve kategorije učitelja/nastavnika s obzirom na godine staža, kao i s obzirom na obrazovanje o darovitima statistički značajno najviše provode posebne programe, metode i oblike rada s darovitima, zatim neposredno skrbe o njima, a najmanje sudjeluju u njihovoj identifikaciji. Skrb o darovitim i talentiranim učenicima u Republici Hrvatskoj još uvijek nije na zadovoljavajućoj razini, a u radu se daju neke smjernice za unapređenje sustava.

Published: November 2017

U istraživanju o volontiranju i vrednovanju volonterskog rada studenata Sveučilišta u Zadru sudjelovalo je 340 studenata preddiplomskih i diplomskih studija s gotovo svih sastavnica te 136 nastavnika iz različitih područja znanosti i akademskih zvanja. Rezultati pokazuju da je u razdoblju od početka studiranja 53% ispitanih studenata volontiralo. Imaju raznovrsna volonterska iskustva, ne samo na sveučilištu i u lokalnoj zajednici, već i u inozemstvu. Povezanost volonterskih aktivnosti s područjem studiranja podjednako im je važna i nevažna, a dominira želja za uključivanjem u kratkoročne aktivnosti i aktivnosti humanitarnog karaktera, potom aktivnosti koje uključuju rad s djecom i aktivnosti koje organiziraju sami studenti. Trećina ispitanih planira se uključiti u aktivnosti koje organiziraju nastavnici na Sveučilištu, ali i volonterske aktivnosti u zajednici i u inozemstvu. Interes postoji i za kulturno-umjetničke sadržaje, sportske, aktivnosti zaštite okoliša, volontiranje u području socijalne skrbi te sa starijima i nemoćnima. Unatoč interesu, istraživanje pokazuje da je potrebno unaprijediti informiranje studenata o volontiranju i volonterskim treninzima za mlade, osobito u skupini studenata-nevolontera. Usporedba stavova nastavnika i studenata pokazala je da obje skupine prepoznaju osobni i društveni značaj volontiranja, za akademsku, i za širu zajednicu. Kod nastavnika postoji interes za informiranjem i stručnim usavršavanjem o temi volontiranja studenata, te društveno korisnom učenju kao nastavnoj metodi. Studenti su željeli da se društveno korisno učenje razvija na Sveučilištu na način da na svakom studijskom programu postoje kolegiji koji koriste tu nastavnu metodu, i to tako da se volontiranje organizira u obliku izbornog kolegija. Dio nastavnika spremni su i žele navedene oblike rada uvrstiti u nastavu, ali žele da im se osigura stručna, administrativna ili logistička pomoć. Nastavnici i studenti složili su se s tvrdnjom da je potrebno nagrađivati (i time poticati) volontiranje. Obje skupine daju prednost pisanim potvrdama i zahvalnicama nad ostalim oblicima nagrađivanja.
Renewal of the Dominican Monastery and Church in Dubrovnik in the 19th Century: Old Library and Church Altars
Authors: Lupis Vinicije B.
Published: November 2017

In this work the author analyzes less known data about the renewal of the Dominican church and monastery in Dubrovnik during the 19th century, paying special attention to three altars, primarily the altar presently located in the church of St. Nicholas in Čilipi which once belonged to the Palmotić family, and altar of St. Vincent Ferrer sold to Muo in 1883 where it is still situated. In the work Viginti supra centum Sanctorum, Beatorum, ac Venerabilim Fratrum Ordinis Praedicatorum Chronologico ordine digestae Imagines by Serafin Marija Crijević, there is a depiction of Blessed Mannes Guzman on the page five, actually a sketch of the present-day altar of St. Dominic in the monastery church. The altar of St. Dominic is the only preserved altar from the Dominican church renewal after the earthquake. For now it is the only altar in Dubrovnik from this period, with preserved original sketch after which it was made, enriching in that way previous insights about the Baroque altars in Dubrovnik.

Published: November 2017

The role of central leptin in regulating the heart from lipid accumulation in lean leptin-sensitive animals has not been fully elucidated. Herein, we investigated the effects of central leptin infusion on the expression of genes involved in cardiac metabolism and its role in the control of myocardial triacylglyceride (TAG) accumulation in adult Wistar rats. Intracerebroventricular (icv) leptin infusion (0.2 µg/day) for 7 days markedly decreased TAG levels in cardiac tissue. Remarkably, the cardiac anti-steatotic effects of central leptin were associated with the selective upregulation of gene and protein expression of peroxisome proliferator-activated receptor β/δ (PPARβ/δ, encoded by Pparb/d) and their target genes, adipose triglyceride lipase (encoded by Pnpla2, herefater referred to as Atgl), hormone sensitive lipase (encoded by Lipe, herefater referred to as Hsl), pyruvate dehydrogenase kinase 4 (Pdk4) and acyl CoA oxidase 1 (Acox1), involved in myocardial intracellular lipolysis and mitochondrial/peroxisomal fatty acid utilization. Besides, central leptin decreased the expression of stearoyl-CoA deaturase 1 (Scd1) and diacylglycerol acyltransferase 1 (Dgat1) involved in TAG synthesis and increased the CPT-1 independent palmitate oxidation, as an index of peroxisomal β-oxidation. Finally, the pharmacological inhibition of PPARβ/δ decreased the effects on gene expression and cardiac TAG content induced by leptin. These results indicate that leptin, acting at central level, regulates selectively the cardiac expression of PPARβ/δ, contributing in this way to regulate the cardiac TAG accumulation in rats, independently of its effects on body weight.
Trends in Hearing Loss Among Adolescents
Authors: Barrett Tyson S. , White Karl R.
Published: November 2017

OBJECTIVES:

Our aim with this article is to evaluate whether the prevalence of hearing loss is increasing among adolescents living in the United States.

METHODS:

All available data about hearing loss among adolescents from the large, federally funded National Health and Nutrition Examination Survey (NHANES) were analyzed. By using the 4 data releases between 1994 and 2010 (a total of 6891 adolescents), the prevalence of adolescent hearing loss >15 and ≥25 dB at low frequencies (0.5, 1, and 2 kHz) and high frequencies (3, 4, 6, and 8 kHz) for bilateral, unilateral, and any loss were calculated.

RESULTS:

Only 13 of 90 comparisons of prevalence across combinations of degree, frequency, and laterality of hearing loss revealed a statistically significant increase at P < .05. Among the 18 subgroups of degree, frequency, and laterality, 61% had a lower prevalence of hearing loss in 2010 than in 1994, and 100% of the subgroups had a lower prevalence in 2010 than in 2006.

CONCLUSIONS:

With previous analyses of NHANES data from 1994 to 2006, researchers showed that hearing loss among US adolescents was increasing. Based on the NHANES data from 1994 to 2010 that are now available, there is no consistent evidence that hearing loss among adolescents in the United States is increasing. Results reveal that conclusions about trends using data from 2 time points can be misleading. NHANES should resume collecting audiometric data as part of their data collection protocol so that trends in the prevalence of childhood hearing loss can be documented.

Published: November 2017

OBJECTIVES:

To illustrate the difficulties in optimal growth monitoring of children with severe obesity or underweight by using the Centers for Disease Control and Prevention (CDC) 2000 age- and sex-specific BMI percentile growth charts. We also aimed to examine the utility of a new modified CDC BMI z score chart to monitor growth in children with normal and extreme BMI percentiles by using real-life clinical scenarios.

METHODS:

Modified BMI z score charts were created by using the 2000 CDC algorithm. Three cases of children with extreme BMI values and abnormal growth patterns were plotted by using the standard CDC 2000 clinical growth chart, the modified BMI z score chart, and the CDC BMI percentile chart, modified to include the percentage of the 95th percentile (%BMIp95) curves.

RESULTS:

Children with severe obesity could not be plotted on the standard CDC BMI percentile chart because their BMI points lay above the chart cutoff. Children with a low BMI (<3%) were also difficult to track on the standard BMI percentile chart. The addition of the %BMIp95 scale to the standard BMI percentile chart allowed tracking of severely obese children; however, it did not address severely underweight children and required a change of units within the chart when transitioning from normal to obese BMIs. The modified BMI z score chart allowed uniform tracking.

CONCLUSIONS:

The modified CDC z score chart is suitable for growth tracking of children with normal and extreme growth patterns; the measures correlate well with the %BMIp95, and the chart can be incorporated easily into existing electronic health record systems for clinical use.

Published: November 2017

Early childhood caries (ECC) is the single most common chronic childhood disease. In the treatment of ECC, children are often given moderate sedation or general anesthesia. An estimated 100 000 to 250 000 pediatric dental sedations are performed annually in the United States. The most common medications are benzodiazepines, opioids, local anesthetics, and nitrous oxide. All are associated with serious adverse events, including hypoxemia, respiratory depression, airway obstruction, and death. There is no mandated reporting of adverse events or deaths, so we don’t know how often these occur. In this article, we present a case of a death after dental anesthesia and ask experts to speculate on how to improve the quality and safety of both the prevention and treatment of ECC.

We estimated the size and shape characteristics of agricultural fields within the administrative area and identified patterns of the margin trends from 1950-1960 till the present time. Here we considered large-scale soil maps for the area of Vasilkovsky district of the Dnepropetrovsk region, which were drawn up in 1950-1960. To assess the landscape metric we used FRAGSTATS program which allow to make conformity assessment of the observed distributions of field sizes regards the normal, exponential, log-normal, gamma, Weibull, and Pareto distributions. We also used Box-Cox transformation to convert the experimental data into the normal distribution law for the further application of the transformed data in regression analysis. We estimated that the area of agricultural fields ranged from 1.20 to 269.00 hectares during the period of large-scale mapping in 1950-1960. The variation limits of the field sizes based on the results of remote sensing data and in our time they are 2,.5-266.57 hectares. Area of the fields in different periods strongly correlate and are statistically significant (r = 0.98, p = 0.00). Field sizes currently associated with the field sizes in the 50-60 years of linear regression. Shape parameters and field sizes significantly correlated, therefore, to establish the main trends of varying shape and size of fields, as well as for non-multicollinearity variables for regression analysis, we performed a multivariate factor analysis. An important aspect of the structuring of the agri-landscape is the location of settlements and, therefore, the fields distance from them. In results obtained indicate that the processes increase and decrease the size of fields in agricultural production are determined by various factors. Aspects of the shape and size of the fields associated with the dynamics of the processes that lead to variations in field areas. Fields that have shown a tendency to change their size, have different characteristics of forms and size from the stable fields. Typically, variable field size is smaller and more complex shapes.

Sodium diclophenac belongs to a group of nonsteroidal anti-inflammatory drugs, which is indicated for inflammatory, degenerative and traumatic lesions system of the skeleton, muscles and connectives tissues. The features of changes in hematological (above all, morphological) indices in Wistar line rats for experimental reproduction of toxic hepatitis at oral introduction of diclofenac sodium in a dose of 12.5 mg / kg of body weight (once a day, within 14 days) were investigated. This rats demonstrated the development of chronic inflammatory process in liver that was characterized by reactive leukocytosis (an increase in the number of leukocytes by a factor of 3), neutrophil right shift, monocytopenia (a decrease in the number of monocytes by a factor of 2.6) together with compensatory lymphocytosis, high values of ESR (by a factor of 5.5), and thymol test (by a factor of 2.9). However, erythrocytopenia (a decrease in the number of erythrocytes by 44 %) – which is a sign of anemia development – was revealed in animals under the experimental toxic hepatitis. Besides it, the hemoglobin content was in the range of normal values that was an evidence of a compensatory role of red bone marrow in the maintaining homeostasis of the respiratory function of blood. There were no changes in blood rheology that was indicated by definite stability of the hematocrit value in sick animals. We registered the development of chronic inflammatory process and anemia in rats caused by experimental reproduction of toxic liver damage by oral introduction of sodium diclofenac.

Published: November 2017

In the North-Eastern part of Ukraine the forest communities occupy considerable area and have great ecological and economic value. In natural forests herbs and subshrubs maintain the canopy cover through the recovery mechanism when the undergrowth of woody plants by height constitutes a part of the herbaceous and subshrub layer. Cenoflora within the lower layers of mixed coniferous-broad leaved forests of the southern part of the Eurasian forest zone is a fairly complete structural unit, especially in the central parts of the moisture and soil fertility gradients. Syntaxonomic adaptability of the lower layer plants of the forest communities in the North-East of Ukraine is established, and their ecological and biological diversity is determined as a result of the researches conducted. A group of species of forest herbs and subshrubs by the ecological status takes an intermediate position because of their habitat versatility. The species of this group are characterized by the vegetative propagation along with the effective seed reproduction. The habitat versatility and combination of the two types of reproduction are the main reasons for a wide representation of the species of this group in different syntaxons. A high floristic biodiversity of the forest communities of the North-Eastern part of Ukraine and their flora heterogeneity are determined based on the comparative floristic analysis. The floristic difference between the two major classes of vegetation in this region is shown, and it is found that Querco-Fagetea class is characterized by a high nutrient status and good warming-up under slightly reduced soil moisture, whereas the main feature of Vaccinio-Piceetea class is low soil fertility.

Experimental studies conducted in terms of problem research laboratory of feed additives National University of Life and Environmental Sciences of Ukraine. Independent experiment was conducted with growing Pharaoh Coturnix quails to determine the optimal valine-to-protein ratio for quail development. We conducted a randomized block experiment with 4 treatments, each with 5 replicates of 25 growing birds (1 to 35 d of age). A diet consisting of soybean and sunflower meal, wheat, corn, Fish meal, sunflower oil, concentrate (28% CP, 2.88 kcal/g on 1 to 21d of age, 20.5 % CP, 2.97 kcal/g on 22 to 35 d of age) having severally 1.54 and 1.33 % valine served as basal feed. Valine was supplemented in four graded levels up to 2.10 g/100 g on 1 to 21d of age and 1.54 g/100 g on 22 to 35 d of age at the expense of L-valine. Diets and water were offered ad libitum.

Body weight gain and feed/gain ratio were studied. Quails significantly responded to the increasing valine concentration in growth, feed/gain ratio. Analysis was used to calculate the Valine nutrient recommendations. These estimates were 1.28 % for the starter and 1.23 % for the total Val for the grower period. Supplementation with Valine to the base diet resulted in body weight gain of quails equal to those fed the control diet (p<0.01). Feed conversion values of quails supplemented with Valine, resulted in an improvement on 2.3 %.

Published: November 2017

In this article, we proposed a rationale for choosing the seeding aggregates to improve the quality of ordinary spring wheat sowing in the moderate arid steppe of the Altai Territory. We determined the actual values and variability of spring wheat sowing quality indicators when different sowing units were used. A comparative evaluation of sowing aggregates was made on the basis of a generalized parameter that characterizes the quality of sowing taking into account their equalization. The study compared the following technologies and seeding machines: direct seeding with the use of the EPPK-2.5 complex; zero technology (No-Till) with sowing complex Condor; traditional technology of cultivation of crops with autumn processing with PG-3-5 gun, presowing processing of APK-7.2 and sowing of SZP-3.6A. The compared variants were randomly located, the sowing was carried out in the third decade of May, the rate of sowing was 5 million virgin grains per hectare, spring soft wheat "Altai 70". Determination of quality parameters of sowing (depth of seeding, the number of plants, plant height and their statistics) were conducted in the 2nd decade of June. During 2013-2016, SZP-3.6A crops had the advantage from the number of shoot and it was 346.1 pcs / m2, which is by 1.84 and 2.34 times was higher than Condor and EPPK-2.5 respectively. The height of plants also had an advantage of SZP-3,6A – 282.6 mm, which was higher by 25.4 mm and 71.2 mm than in Condor and EPPK-2.5 respectively. Each indicator of the quality of sowing was characterized by fluctuated magnitude. High coefficient of variation indicated low quality of sowing. We calculated the equalization coefficient for each parameter to assess the uniformity of crops performed by each machine. The SZP-3,6A seeder exceeded the compared seeding complexes for all three parameters, which indicated higher seed uniformity than Condor and EPPK-2.5. Comparative evaluation of the seeding machines Condor and EPPK-2.5 was ambiguous. At the seeding unit EPPK-2.5, the leveling factor was 12.3% higher than in Condor, the seeding rate was 17.8% lower in comparison with Condor, and the plant height was insignificantly (by 2.1%) lower than Condor.

We suggested a generalized leveling factor to evaluate the sowing aggregates in terms of the quality of sowing, i.e. radius vector drawn up to point A, characterized by the coordinates A (depth of embankment, number of sprouts, and plant height). A better seeding was obtained with the SZP-3.6 A seeding unit (84.2%). The lowest quality parameters for sowing were obtained from the seeding complex EPPK-2.5 (75.9%). Crops with this complex were characterized by the greatest uneven quality of sowing, which requires a correct justification for both the sowing rate, the method of sowing and the width of the rows of cultivated crops according to the technology applied to specific conditions.

Published: November 2017

Aquatic environments face a variety of threats in the Hondo River basin, Southeastern Yucatan Peninsula. Some of these impacts, like pollution by pesticides, may depend on land use and cover. Our objective was to assess the effect of land use/cover using a previously published index of biotic integrity (IBI), based on fishes and designed for shallow streams in the Hondo River basin. Our hypothesis was that land uses that cause deforestation and pollution, such as urbanization, cattle breeding, or sugar cane fields, would be reflected in low IBI values, at least at some spatial scales. The 23 sites originally used in 2008-2009 to estimate by electrofishing the relative abundance and other characteristics of selected fish species and guilds to construct the IBI, were revisited in February 2010, to validate by direct inspection the type of land use/cover suggested by landscape information in digital databases. We analyzed the effect of seven types of land use/cover (agriculture, pasture, human settlements, water bodies, wetlands, forest, and secondary vegetation) on the IBI values, at four spatial scales, i.e., the percent of every land use/cover at progressively larger circles (125, 250, 500, and 1 000 m diameter) centered on the water body where the IBI value was measured. Correlations were established among the percent land/use cover by scale around 23 sites, and with their corresponding IBI values. Then, Student’s t tests were calculated to examine significant differences in land use/cover between groups of localities above and below the median IBI value, and Mann-Whitney’s U tests were applied to compare IBI values between localities with and without a given landscape cover. Agriculture, human settlements, and secondary vegetation correlated negatively with the IBI; forests positively.  Differences were significant (p < 0.05) for forest (higher in sites with higher IBI values) and human settlements (lower in sites with higher IBI). Of all the landscape categories located in the Hondo River basin, with the exception of pasture, those of anthropogenic origin tended to be detrimental to aquatic biotic integrity.

A new high-performance liquid chromatographic (HPLC) method for determination of triclosan (TCS) and flurbiprofen (FBP) was successfully developed and validated at a single wavelength. The method involves extraction of the targeted drugs from nanogels and simulated saliva by using methanol as the extractant. The Agilent ZORBAX SB-C18 column (5 μm, 4.6 × 250 mm) was used for the chromatographic separations. The effects of various parameters were extensively evaluated and optimized. The optimal HPLC conditions were acetonitrile and 0.001 M citric acid (90:10, v/v) with a pH of 3.24 as the mobile phase, at a 0.3 mL/min flow rate under isocratic elution mode. Excellent sensitivity and specificity were achieved by ultraviolet (UV) detection at 242 nm. The method also demonstrated excellent linearity within the test range of 10–100 μg/mL with the correlation coefficient (R2) of 0.9998 for both the analytes. The practical applicability of the method was demonstrated by recovering TCS and FBP from nanogels and simulated saliva. The recovery of the analytes from the nanogels and the spiked simulated saliva samples was in the range of 97–98% and 96–99%, respectively, and their respective relative standard deviation (RSD) was less than 0.9% in both cases. System suitability parameters were found to be within acceptable limits. The method is simple, specific, and precise, and to the best of our knowledge, it is the first reported validated quantitative HPLC method for the concurrent determination of TCS and FBP in a pharmaceutical dental product. The method can be useful in the routine quality control analysis of dental formulations with TCS and FBP contents or products with a similar composition.

A simple, rapid, and sensitive liquid chromatography–tandem mass spectrometry (LC–MS/MS) method was developed and validated for the determination of zinc pyrithione (ZnPT) and pyrithione (PT) in shampoos. The method consisted of a liquid–liquid extraction for sample preparation. The mass spectrometer was operated in multiple reaction monitoring (MRM) mode via the positive electrospray ionization interface. A linear regression (weighted 1/x) was used to fit calibration curves over the concentration range of 50–2000 ng/mL for both ZnPT and PT. Excellent linearity (r2 ≥ 0.9996) was achieved for all. The method was validated and found to be accurate (95.9–108.2% for ZnPT and 94.9–110.4% for PT), precise, and selective. Analytes in shampoos were found to be stable in the autosampler (6 °C for 6 h), in room temperature (for 6 h), and after three freeze–thaw cycles, and recovery of analytes was reproducible (90.8–94.6% for ZnPT and 90.2–96.3% for PT).

This article was migrated. The article was not marked as recommended. Objective：The aim of this study was to identify the disciplines that strongly correlated with neurology, and to compare the differences between neurology and other disciplines in targeted integration. Method: Scores of 18 disciplines (six clinical disciplines, seven basic disciplines, and five social science/humanities disciplines) and college entrance examinations of 275 eight-year program medical students from Sun Yat-Sen University were collected. Correlation between any two subject scores were determined. Results: Student scores in neurology had significant correlation with the scores of four clinical subjects, five basic subjects, and one social science/ humanities subject. Internal medicine scores showed significant correlation with the scores of three clinical subjects and two basic subjects. Scores from obstetrics and gynecology, pediatrics and psychiatry significantly correlated with one to three clinical subjects scores. No significant correlation was found between surgery scores and other subjects. With the exception of medical statistics, there was no significant correlation between scores from social science/humanities subjects and scores from either clinical or basic subjects. No subject scores significantly correlated with the college entrance examination scores. Conclusion: Neurology is associated with more clinical and basic disciplines than other subjects. Neurological education should involve a targeted integration with other closely related disciplines.

Published: November 2017

The professor’s academic activities remain most important in their work, but in Lithuania they acquire and develop this kind of competences in a rather spontaneous way, paying little attention to which competences should be expanded, the needs of the development of their academic work are not stressed.

The aim of the research is to determine demands of professional development of higher school professors referring to their opinions about the areas they lack knowledge and skills. The following research methods have been employed: analysis of scientific sources, focus group discussion, statistical data analysis. During the research 197 university and college lecturers were interviewed.

The analysis of the findings enabled to distinguish the following groups of lecturers’ andragogic skills according the areas of activities. That is: individual and group support for students, supervision; organizing lecturing activities, stimulation of students’ study activities; application of new technologies in the study process; creation and development of study programs; analysis of study programs and their revision; administrative and managerial; nurturing of personal culture and professional development.

It has been established that university lecturers under the investigation admit a considerable demand to perfect academic skills which are directly linked to their work with students. To be more precise, referring to the respondents, they need more knowledge and skills that would be helpful to organize lecturing activities and stimulate students learning activities. They feel a lesser need for knowledge and skills how to organize individual or group support for students, manage them, partially apply internet technologies, create and develop study programs, to properly implement administrative and managerial activities, expand personal culture and professional development. It should be noted that lecturers are aware of the lack of speciality knowledge and skills.

Breast imaging in patients with nipple discharge
Authors: Paula Ivie Braga de , Campos Adriene Moraes
Published: November 2017

Abstract Nipple discharge is a common symptom in clinical practice, representing the third leading breast complaint, after pain and lumps. It is usually limited and has a benign etiology. The risk of malignancy is higher when the discharge is uniductal, unilateral, spontaneous, persistent, bloody, or serous, as well as when it is accompanied by a breast mass. The most common causes of pathologic nipple discharge are papilloma and ductal ectasia. However, there is a 5% risk of malignancy, mainly ductal carcinoma in situ. The clinical examination is an essential part of the patient evaluation, allowing benign nipple discharge to be distinguished from suspicious nipple discharge, which calls for imaging. Mammography and ultrasound should be used together as first-line imaging methods. However, mammography has low sensitivity in cases of nipple discharge, because, typically, the lesions are small, are retroareolar, and contain no calcifications. Because the reported sensitivity and specificity of ultrasound, it is important to use the correct technique to search for intraductal lesions in the retroareolar region. Recent studies recommend the use of magnetic resonance imaging in cases of suspicious nipple discharge in which the mammography and ultrasound findings are normal. The most common magnetic resonance imaging finding is non-mass enhancement. Surgery is no longer the only solution for patients with suspicious nipple discharge, because short-time follow-up can be safely proposed.

Buen Vivir (Sumak Kawsay): definiciones, crítica e implicaciones en la planificación del desarrollo en Ecuador
Authors: Arteaga-Cruz Erika Lorena
Published: November 2017

RESUMEN Con la transición de gobiernos progresistas en la región mientras en Ecuador se mantiene el progresismo, vale recordar algunos hitos del contexto ecuatoriano y la disputa por la acumulación del capital reflejada en el modelo de desarrollo. Este ensayo analiza el Buen Vivir/Sumak Kawsay como alternativa civilizatoria y aborda los planes nacionales de desarrollo. A pesar de que en un inicio se planteó otro modo civilizatorio, con el paso de los años poco se logró concretar de cambio y transformación; una mirada a la década anterior nos deja de saldo un Estado Ecuatoriano moderno, capitalismo con rostro humano. A pesar del vaciamiento del concepto, vale la pena seguir disputando esa dimensión.
