Today, the development of technology and information is rapidly advancing in various aspects of life, one of which is in the academic field, from elementary schools to universities. Nowadays, schools are increasingly using information technology in their academic management, making it easier to handle related data.
Vocational schools, or SMKs, provide secondary education with the role of preparing students to enter the workforce. SMKs have an institution called the Special Labor Exchange (BKK), which serves as a placement service for workers in both secondary and higher education units. The Special Labor Exchange acts as a bridge between SMKs and the industrial world.
SMK Nurul Islam Cianjur is a private school in the form of a foundation. This school also offers a Special Labor Exchange (BKK) program primarily for its alumni but is also available to students from other schools.

Folio Sheeter Division is a division of PT. Indah Kiat Pulp And Paper, which is located in Siak Regency, which is one of the leading paper mills in Riau Province. The Folio Sheeter Division requires an application that can process production data. The application can only be accessed internally, the production process is a company secret because in production there are several mix processes or mix formulations of quality and production quality so that the materials and data are not published. The process is digital text that is encrypted by user to user. Every production result, the supervisor will inform the assistant about the combination of the mix of production materials that will be processed to carry out production according to what consumers want. From the author's observations at the research site that the information shared by supervisors can be read by all employees or staff, this information can be seen clearly by users or staff who are not interested so that the production and process data can be known by other staff who are not interested, so it is possible that the data could be given to irresponsible parties. The types of data or files that exist are in the form of data records and supporting document files such as doc, xls and pdf. Production data will be encrypted with cryptographic techniques so that production data cannot be seen by others but the user himself or the user who is permitted in the form of decryption who can access it. Notification of information to staff or assistants is still fairly manual, because the provision of information in paper form and easily read by others. For this reason, the authors are interested in using the AES 128 algorithm to encrypt and decrypt data so that the process and production results in the form of data can be maintained.

Visibilidade midiática no Jornal Nacional: atores políticos no debate público sobre a reforma da previdência
Authors: Santos Carlos Roberto Praxedes dos , Maurer Camila
Published: January 2023

Este trabalho verifica a visibilidade de diferentes atores políticos no debate público midiático acerca da Proposta de Emenda Constitucional (PEC) de reforma da Previdência Social, identificando quais sujeitos têm acesso à esfera de visibilidade oferecida pelo Jornal Nacional, produto jornalístico de maior audiência no Brasil, com 45 milhões de espectadores diários. Para isso, são analisadas 30 edições do telejornal em questão, veiculadas entre os dias 20 de fevereiro e 26 de março de 2019. O referencial teórico tem como base o conceito de esfera pública cunhado por Habermas (1984, 1997) e explora questões relacionadas ao potencial da mídia para a construção de espaços deliberativos, tomando a questão da visibilidade como conceito central de análise, a partir do exposto por Maia (2008), Marques (2009) e Gomes (2008). Conclui-se que o debate que se desenvolve no interior da cena midiática do Jornal Nacional privilegia atores políticos institucionais, em detrimento de representantes de outros setores da sociedade.

Published: January 2023

Este artigo tem o objetivo de analisar como é produzido um problema público quando não havia desinformação no sistema classificatório vigente no período da vacinação para idosos nos anos de 1999 e 2000. Para tal, realizamos uma pesquisa documental na Hemeroteca Nacional, nos acervos e nas páginas dos jornais de grande circulação da época, Jornal do Brasil, Folha de São Paulo, O Globo e O Estado de S. Paulo. Vimos que as notícias além de tentarem consensualizar   representações sobre a campanha e seu público-alvo, também buscavam desmentir boatos acionando diferentes atores para conceder legitimidade à narrativa. Nesse sentido, discutimos o que é boato e suas principais diferenças para compreender o que vem a ser desinformação.

Introduction. Visual-motor integration (VMI) is defined as the degree to which visual perception (VP) and finger-hand movements are well coordinated. The VMI consists of two components: VP and motor coordination (MC). The main goal of our research was to determine whether there are differences in age and gender categories in VMI, VP and MC scores, as well as whether there is a correlation between VMI and school success of younger school-aged children. 

Methods. Out of 103 student respondents, 52 were female (50.5%), aged 6 to 11 years (8.05 ± 1.44 years), divided into two groups according to age: 6–8 years (first, second and third grade) and 9–11 years (fourth to fifth grade). Data on the level of VMI were obtained by applying the following tests: Beery-Buktenica Developmental Test of VMI, VP test and MC test. 

Results. In the older age group of subjects, a significant difference was observed in the mean values of the score on the VMI (12.67 ± 1.92), VP (23.69 ± 3.21) and MC (24.34 ± 3.23) tests comparing to the younger group of subjects (9.98 ± 2.12; 20.80 ± 3.2; 19.65 ± 3.82) (p < 0.001), while the difference in the mean values of scores in relation to gender was not observed. A significant, positive and strong correlation was observed between the scores on the VMI, VP and MC test with the success of second to fifth grade students (p < 0.050). 

Conclusion. Given such a strong correlation between VMI and the success of younger students, we conclude that it is important that VMI disabilities are identified in time, so that these students can be referred for further assessment and receive the necessary support.
El partido político como actor decisivo de la regulación mediática. Las políticas de comunicación de los gobiernos del Frente Amplio en Uruguay
Authors: Schuliaquer Iván
Published: January 2023

Los gobiernos del Frente Amplio en Uruguay promovieron políticas de comunicación que redujeron el peso de los grandes grupos mediáticos privados y reconocieron legalmente a nuevos actores. Si bien otros gobiernos izquierda sudamericanos a inicios del siglo XXI hicieron lo mismo, la particularidad uruguaya es que eso se dio sin confrontación pública entre gobierno y empresas mediáticas. Este artículo explora cómo fue posible esa combinación atípica. Para ello, indaga en las políticas de comunicación entre 2005 y 2015 a través de una estrategia de process-tracing que se focaliza en las interacciones entre los actores involucrados. En la década analizada, los gobiernos negociaron sus apariciones mediáticas de maneras que consideraron convenientes y los grupos mediáticos, que se percibían más débiles que el gobierno, lograron negociar las políticas de regulación y preservar parte del statu-quo. Ante ese panorama, ninguno de los dos actores buscó romper la relación. No obstante, hubo un tercer actor: el Frente Amplio, partido gobernante, que desde su centralidad, atípica para Sudamérica, jugó un rol definitorio en las políticas de comunicación. Primero, durante el gobierno de Tabaré Vázquez (2005-2010), y contra la voluntad del presidente, actuó como veto player para impedir el ingreso de los grandes grupos mediáticos en las telecomunicaciones y resguardar a Antel, la empresa estatal líder en servicios de telefonía e internet. Segundo, fue el impulsor de una ley marco para los servicios de comunicación audiovisual que, aunque no contó con un impulso claro del presidente, fue aprobada durante el gobierno de José Mujica (2010-2015).
El impacto del confinamiento por la COVID-19 en el curso académico. Caso de estudio: el alumnado de etnia gitana
Authors: Rodrigo-Martín Isabel , Rodrigo-Martín Luis , Pérez-García Álvaro , Muñoz-Sastre Daniel
Published: January 2023

La virtualización urgente de la actividad académica en los centros educativos obligada por el confinamiento que se decretó en España entre los meses de marzo y mayo de 2020 supuso un reto hasta entonces desconocido para toda la comunidad educativa. Las tecnologías de información y de la comunicación se convirtieron en herramientas imprescindibles para garantizar la continuidad del curso. Esta situación puso de manifiesto las carencias que en materia de equipamiento tecnológico presentan los colectivos más vulnerables de la población e incrementó, si cabe aún más, la «brecha digital» poniendo en riesgo el seguimiento y el rendimiento escolar de los alumnos de estos sectores. Entre los colectivos más afectados se encuentra el de los estudiantes de etnia gitana tal y como se puso de manifiesto en centros como el CEIP Nueva Segovia, (Segovia, España). El presente trabajo es el resultado de una investigación cualitativa y cuantitativa realizada en dicho centro escolar y que ha permitido identificar y analizar los dispositivos tecnológicos disponibles por el alumnado de etnia gitana, la percepción que tienen los diferentes miembros de la comunidad educativa sobre el uso de las tecnologías y, por último, la formación de dichos miembros en relación con las nuevas tecnologías. Los resultados revelan las necesidades no solo de equipamiento, sino también formación en nuevas tecnologías que presentan tanto familias como estudiantes. Estos resultados permiten advertir la importancia que tiene realizar un nuevo planteamiento curricular para el alumnado con necesidades de compensación educativa que elimine esta situación de desigualdad.
Mask making on social media: Women’s mask making practices and advocacy during the COVID-19 pandemic
Authors: Perreault Mildred , Richards Melanie
Published: January 2023

Background: COVID-19, the disease caused by the virus SARS-COV-2, can create serious respiratory problems, or even death, for those affected. Individuals who share messages about its risks and related risk reduction behaviors have the potential to make a broader health impact. Early in the pandemic, some individuals made homemade masks to address the limited supply of personal protective equipment (PPE) and posted about their efforts on social media. Aim: To understand the grassroots application of the Crisis and Emergency Risk Communication (CERC) theoretical model concerning effective messages in early phases of a crisis. Methods: Using both individual interviews and observations, researchers conducted a study of 15 Appalachian women making masks during the Covid-19 pandemic and analyzed 9 of their social media accounts. Results: Through interviews and observations, the researchers gained understanding as to how mask makers used social media to create and distribute masks and engage their communities. Social media messages often contained calls to action, personal connections to the issue, and supported the mask makers’ efforts to reach a broader network of individuals. Discussion: An evaluation of the grassroots efforts of mask makers extends the CERC framework to the individual level. Conclusions: This study provides insight into the role of grassroots health advocacy, and the role of user-generated social media messaging in pandemic risk reduction.
Framing entrepreneurial actorness from a value-theoretical perspective: A comparative analysis of European specificities
Authors: Grunhut Zoltán , Bodor Ákos
Published: January 2023

This paper claims that entrepreneurial actorness, which is one of the main thematic scopes of entrepreneurship research, can be (re-)framed from a value-theoretical perspective. The various individual features addressed as entrepreneurial personality traits (one’s ideas, perceptions, understandings, mindsets, routines, etc.) can thus be linked to certain value contents and specific value sets. For the purposes of this novel theoretical perspective, this paper first applies Shalom H. Schwartz’s framework of Basic Human Values, before presenting a comparative analysis of European entrepreneurs’ value preferences. The results show that there are four separate entrepreneur groups with significantly different value hierarchies whose distribution varies across Europe.

Published: January 2023

Cet article vise à expliciter les conditions pragmatiques dans lesquelles la scénarisation de jeux vidéo se pratique au Québec, et la réalité des métiers qui lui sont associés. En s’appuyant sur des témoignages recueillis auprès de trois praticiennes qui travaillent à la scénarisation de jeux vidéo dans des studios à Montréal, les auteur·rices décrivent la démarche de création d’un jeu vidéo, les différences entre les entreprises AAA et indépendantes, et les enjeux entourant la scénarisation selon les différents types de projets et leurs ambitions narratives. Sont abordées les différences entre conception narrative (narrative design) et écriture (writing), ainsi que les formes que prennent les documents scénaristiques pour contribuer à un « scénario » vidéoludique, terme qu’il faut repenser autant que le nom de « scénariste » pour ce médium interactif.
« DIVERSITÉ SCÉNARISTIQUE » : UNE DISCUSSION CHORALE
Authors: Tremblay Gabrielle ,   Neuf auteur·rices anonymisé·es
Published: January 2023

La scénarisation est une expérience socioprofessionnelle qui s’inscrit nécessairement dans un contexte de travail soumis à différentes dynamiques de pouvoir et d’oppression, d’inclusion et d’exclusion – tantôt volontaires, tantôt systémiques. À travers une série de fragments d’entretiens réalisés à l’automne 2021, ce texte à dix têtes investit la question de la « diversité scénaristique » dans le contexte québécois contemporain. Ce faisant, la « discussion chorale » qui se déploie au fil des pages rend compte de préoccupations actuelles et cible des pistes de réflexion peu considérées jusqu’à présent au sein des études scénaristiques au Québec.
PROJET MÉMORIAL ET POSTURES MULTIPLES
Authors: Nadeau Marie-Hélène
Published: January 2023

Désormais exhumés des archives par la publication récente de Georges Aubin, les
Mémoires d’Amédée Papineau, fils aîné du grand Louis-Joseph, proposent un étonnant
diptyque : une première partie d’une introspection pleine de charmes, exprimée dans une
prose excellente et respectant les codes du genre mémorialiste ; une seconde, impersonnelle,
largement historiographique, où la prose laisse place à une retranscription de documents
officiels et à des entrées diaristiques en lien avec les rébellions de 1837-1838. De ce
projet mémorial se dégagent trois postures que cet article met en lumière : celle du
mémorialiste, qui permet d’inscrire le texte dans un genre en formation ; celle du
collectionneur, marquée au coin d’un sens de l’observation aiguisé et d’une forte conscience
historique se traduisant par l’importance de la conservation ; celle de l’historien,
poussant Papineau à répondre aux silences de l’Histoire. Ces trois postures analysées,
l’objet de l’oeuvre, sa destinée et son caractère curieux deviennent intelligibles et
éclairent ainsi l’entreprise narrative de Papineau au soir de sa vie.
Morphological diversity of tomato accessions from the Gene Bank of the Republic of Srpska
Authors: Rašeta Sonja , Antić Marina , Todorović Vida
Published: January 2023

In this research the aim was to determine differences in morphological characteristics between 11 tomato accessions from the Gene Bank of the Republic of Srpska. The experiment was conducted and analysis was performed during the 2018 and 2019 seasons. A total of 16 morphological characteristics (9 quantitative and 7 qualitative) were analyzed according to International Plant Genetic Resources Institute (IPGRI) descriptors for tomato. The results showed that polymorphism (diversity) was present in all quantitative characteristics and in 6 qualitative characteristics, while only one qualitative characteristic was monomorphic (no differences between accessions). Thereby, polymorphism was present in 93.75% of morphological characteristics. Out of a total of 9 quantitative characteristics, a highly significant difference (p 0.01) was found in all characteristics except for the 1000-seed weight since this characteristic had only one value per accession measured according to the IPGRI tomato descriptors. The accessions from the Gene Bank of the Republic of Srpska have shown high diversity in all qualitative characteristics except in plant growth type, which was indeterminate in all analyzed accessions. This research provides a new insight into the research area of diversity of tomato landraces from the Republic of Srpska, which is important for further promotion and sustainable use of germplasm not only for scientific research purposes but also for national rural farmers, who are the key to preserving traditional knowledge and skills related to the cultivation and use of traditional varieties and tomato landraces.

Published: January 2023

This paper presents the results of a two-year study of six selected soybean genotypes with the aim of examining which of the genotypes in the given production conditions give the best results in regards with the amount and quality of seed yield. All genotypes belong to a zero-maturity group. The correlation between the grain yield per plant and other studied traits was tested through linear (simple) correlations. The testing showed that the following traits had a positive highly significant impact on seed yield: the number of seeds per plant (0.917**), seed germination energy (0.897**), seed moisture content (0.803**), plant height (0.802**), seed germination (0.789**), the number of seeds in pods (0.696**), the number of harvested plants per m-2 (0.590**), the number of plants (phenophase 1-3 in the three-leaf stage) per m2 (0.550**), 1000 seed mass (0.471**), and the height to the first node (0.412**).
Results of monitoring spotted wing drosophila (Drosophila suzukii, Matzumura) in the Republic of Srpska (Bosnia and Herzegovina) for the 2017-2021 period with reference to seasonal population movement
Authors: Nikolić Petar , Lisica Marko , Nježić Branimir
Published: January 2023

Spotted wing drosophila (SWD) - Drosophila suzukii, Matzumura is an important pest of soft and pome fruits. It originates from Asia, now spread throughout Europe, North, and South America. High reproductive potential, many generations per year, and their overlapping have made this pest hard to control. In Bosnia and Herzegovina, SWD has been present at least eight years and for that time little data has been collected on how it spreads and behaves in the agroecological conditions of the Republic of Srpska. Monitoring was conducted in the 2017-2021 period in orchards of different plant hosts. SWD was found in all agriculture regions of the Republic of Srpska with difference in population number. SWD adults are most active from the end of August and are most harmful for grape, blackberry, and late raspberry varieties. Considering climate conditions, population movement was most influenced by precipitation and air temperature.
Adaptability of indigenous vegetation on parking lots – A case study: Tree alleys in Novi Sad, Serbia
Authors: Čukanović Jelena , Đorđević Sara , Kolarov Radenka
Published: January 2023

In this study five indigenous species on parking lots in Novi Sad, Serbia were examined (Acer platanoides ‘Globosum’, Celtis australis L., Tilia tomentosa Moench., Carpinus betulus ‘Fastigiata’, and Corylus colurna L.). The aim of this study is to represent their adaptability to urban stress and harsh environmental conditions which are present on parking lots by valuing their dimensions and vitality. Results showed that well-adapted species are Celtis australis L. and Carpinus betulus ‘Fastigiata’. Other species had low vitality values, asymmetrical canopy, and mechanical damages that were caused by insufficient root and canopy space and insufficient distance from buildings and traffic. Choosing well-adapted indigenous species for alleys can be very challenging. Adaptability assessment of indigenous trees on parking lots in Novi Sad can be used as guidance to urban planning in Novi Sad and other cities which have a high share of pavement to reduce the climate change effect.
Land suitability for the cultivation of corn (Zea mays) in the municipality of Bužim
Authors: Ičanović Mirsad , Marković Mihajlo
Published: January 2023

Rational use of available land is of great importance for the economic development of every society, especially considering the fact that soil is the primary production resource, thereby placing an even greater importance on its protection and conservation, but also on the correct use of it. This paper focuses on the municipality of Bužim, located in the north/western part of Bosnia and Herzegovina, where the soil suitability for the purposes of corn cultivation were assessed and examined by using the FAO (1976) methodology of AEZ (agroecological zoning), which uses input data such as soil characteristics, climate change, relief patterns of the investigated area, and the requirements of the agricultural crops. Within the municipality of Bužim, 13,026.27 ha of the land is used for agricultural purposes. In regards with the corn, one distinguishes between two categories ofsoil suitability: the suitable classes (S1, S2, S3), which occupy more than 43.44% of the land surface, and the unsuitable class (the N class), which only occupies 0.94% of the land surface. Thus, it can be concluded that conditions necessary for corn do exist within the municipality of Bužim, in the form of land resources, and higher yields can be achieved by implementing landscaping measures and introducing new corn varieties in accordance with the latest scientific and expert achievements.

Nutrient availability fluctuates in most natural populations, forcing organisms to undergo periods of fasting and re-feeding. It is unknown how dietary changes influence liver homeostasis. Here, we show that a switch from ad libitum feeding to intermittent fasting (IF) promotes rapid hepatocyte proliferation. Mechanistically, IF-induced hepatocyte proliferation is driven by the combined action of systemic FGF15 and localized WNT signaling. Hepatocyte proliferation during periods of fasting and re-feeding re-establishes a constant liver-to-body mass ratio, thus maintaining the hepatostat. This study provides the first example of dietary influence on adult hepatocyte proliferation and challenges the widely held view that liver tissue is mostly quiescent unless chemically or mechanically injured.

A feature boosted deep learning method for automatic facial expression recognition
Authors: Podder Tanusree , Bhattacharya Diptendu , Majumder Priyanka , Balas Valentina Emilia
Published: January 2023

Automatic facial expression recognition (FER) plays a crucial role in human-computer based applications such as psychiatric treatment, classroom assessment, surveillance systems, and many others. However, automatic FER is challenging in real-time environment. The traditional methods used handcrafted methods for FER but mostly failed to produce superior results in the wild environment. In this regard, a deep learning-based FER approach with minimal parameters is proposed, which gives better results for lab-controlled and wild datasets. The method uses features boosting module with skip connections which help to focus on expression-specific features. The proposed approach is applied to FER-2013 (wild dataset), JAFFE (lab-controlled), and CK+ (lab-controlled) datasets which achieve accuracy of 70.21%, 96.16%, and 96.52%. The observed experimental results demonstrate that the proposed method outperforms the other related research concerning accuracy and time.

Wood quality is an important indicator for modern sawmills. Internal wood characteristics can be derived from their correlations with external appearances. In this study, we developed linear regression models to predict knot size from surface features of Mongolian oak (Quercus mongolica) using data collected from 53 trees. For this, manual measurements and X-ray computed tomography scanning technology was respectively used to obtain internal and external features of 1,297 knots. Our results showed that Mongolian oak knots were generally concentrated in the middle part of oak stems, with fewer knots observed at the top and base. The parameters of knot and scar showed significant correlations (P < 0.01), where length and diameter of the corresponding external scar increase with increasing the length and diameter of a knot. The corresponding external scar can be used as an effective indicator to predict the internal value of oak logs. The accuracy of our constructed model is more than 95% when assessed against independent test samples. These models thus can be applied to improve the practical production of oak timber and reduce commercial loss caused by knots. These additional data can improve the estimation of the influence of knots on wood quality and provide a theoretical foundation for investigating the characteristics of hardwood knots.

Novel peripheral light-harvesting (LH) complex designated as LL LH2 was isolated along with LH4 complex from Rhodopseudomonas palustris cells grown under low light intensity (LL). FPLC-MS/MS allowed to reveal PucABd and PucBabc apoproteins in LL LH2 complex, which is different from previously described LH4 complex containing PucABd, PucABa and PucBb. The main carotenoids in LL LH2 complex were rhodopin and 3,4-didehydrorhodopin. Three-dimensional modeling demonstrated which amino acid residues of all the β-subunits could interact with carotenoids (Car) and bacteriochlorophyll a (BChl a). Analysis of amino acid sequences of α-subunits of both LL complexes showed presence of different C-terminal motifs, IESSVNVG in αa subunit and IESSIKAV in αd subunit, in the same positions of C-termini, which could reflect different retention force of LL LH2 and LH4 on hydroxyl apatite, facilitating successful isolation of these complexes. Differences of these LL complexes in protein and carotenoid composition, in efficiency of energy transfer from Car to BChl a, which is two times lower in LL LH2 than in LH4, allow to assign it to a novel type of light-harvesting complex in Rhodopseudomonas palustris.
Bidirectional effect of vitamin D on brown adipogenesis of C3H10T1/2 fibroblast-like cells
Authors: Mukai Takako , Kusudo Tatsuya
Published: January 2023

Background

Brown adipose tissue (BAT) dissipates caloric energy as heat and plays a role in glucose and lipid metabolism. Therefore, augmentation and activation of BAT are the focus of new treatment strategies against obesity, a primary risk factor of metabolic syndrome. The vitamin D system plays a crucial role in mineral homeostasis, bone metabolism, and cell proliferation and differentiation. In this study, we investigated the effects of vitamin D3 [1,25(OH)2D3] on brown adipocyte differentiation.

Methods

The mouse fibroblast-like cell line C3H10T1/2 was differentiated into brown adipocytes in the presence of 1,25(OH)2D3. The effect of 1,25(OH)2D3 on brown adipocyte differentiation was assessed by measuring lipid accumulation, the expression of related genes, and cytotoxicity. The viability of C3H10T1/2 cells was measured using the Cell Counting Kit-8 assay. Gene expression was investigated using quantitative reverse transcription-polymerase chain reaction. Protein expression was estimated using western blotting.

Results

1,25(OH)2D3 inhibited adipocyte differentiation and exerted a cytotoxic effect at 1 nM. However, in the physiological concentration range (50–250 pM), 1,25(OH)2D3 promoted uncoupling protein 1 (UCP1) expression in C3H10T1/2 cells. This effect was not observed when 1,25(OH)2D3 was added 48 h after the initiation of differentiation, suggesting that the vitamin D system acts in the early phase of the differentiation program. We showed that 1,25(OH)2D3 increased the expression of two key regulators of brown adipogenesis, PR domain containing 16 (Prdm16) and peroxisome proliferator-activated receptor γ coactivator-1α (Pgc1α). Furthermore, 1,25(OH)2D3 increased Ucp1 expression in 3T3-L1 beige adipogenesis in a dose-dependent manner.

Conclusion

These data indicate the potential of vitamin D and its analogs as therapeutics for the treatment of obesity and related metabolic diseases.

Published: January 2023

The anti-pepsin enzyme (HIV-1) activities of crude extract of Vernonia amygdalina and Cymbopogon citratus were investigated using standard methods. A portion (0.5cm3) of pepsin enzyme solution was measured and transferred into viels, 2 cm3 of hemoglobin and 1 cm3 of the extracts were mixed together. The procedure was repeated for all the different extract. A standard control was also prepared using hemoglobin, enzyme and the various concentrations of the anti-retroviral drugs. A negative control was ran using only hemoglobin and pepsin enzyme whereas positive control was ran along with the standard using hemoglobin, enzyme and various concentrations of antiretroviral drugs. The mixture was allowed to incubate at 37 ºC, after 20 mins, 700 µl of 5% TCA was added to stop the reaction. It was then centrifuged at 14000 rev/min for 5 mins and the supernatant was collected. Absorbance was recorded spectrophotometrically at 280 nm. Each sample was taken in triplicate. UV-Visible spectrophotometer was used to detect the absorbance at 280 nm. The results of the anti-pepsin enzyme (HIV-1) activities showed that petroleum ether fraction of Cymbopogon citratus exhibited wavelength of maximum absorption (גmax) ranging from 0.788 nm - 0.789 nm and its ethyl acetate fraction exhibited גmax absorption ranging from 0.785 nm- 0.788 nm. Petroleum ether fraction of Vernonia amygdalina exhibited גmax absorption ranging from 1.383 nm-1.399 nm while its ethyl acetate fraction exhibited גmax absorption ranging from 1.384 nm-1.400 nm. The result of this work shows that both Cymbopogon citratus and Vernonia amygdalina ethyl acetate fraction have higher activity with Vernonia amygdalina being the highest. Column chromatography of the ethyl acetate fraction of Vernonia amygdalina led to the isolation of the compound which shows higher activity (1.384 nm- 1.400 nm). Available spectroscopic data using 1H NMR, 13C NMR and IR showed that the compound could be β-Sitosterol. The result of this work therefore showed that the extract from the leaves of Vernonia amygdalina could be used for the treatment of HIV-1(since it has the same sequence and family with the pepsin enzyme) and other diseases caused by targeted virus.

Aims: Cardiovascular disease (CVD) is the leading cause of death in dialysis patients as well as in kidney transplant recipients (KTx). Left ventricular hypertrophy (LVH) starts early during the course of chronic kidney disease and is a strong predictor of CVD. We hypothesised that kidney transplant is significantly associated with improvement in cardiovascular reserve. We conducted a prospective study to compare changes in CV before and after kidney transplantation in patients with ESRD who received KTx to control individuals who received PD but did not receive a KTx.

Study Design: A Case-Control Study.

Place and Duration of Study: Clinic for nephrology Clinical Center University of Sarajevo, Bosnia and Herzegovina.

Methodology: In this case-control study, we included 50 KTx from the Kidney Transplant Outpatient Clinic for nephrology Clinical Center. For each 50 KTx, PD outpatients matched for gender and age were recruited.  All patients underwent transthoracic echocardiography, and LV (left ventricular) mass (LVM), LV mass index (LVMi), and indices of cardiac function were measured. In the small subgroup of 18 KTx, we retrospectively assessed and compared the LVMI measurements, during dialysis and the post-transplant period.

Results: The prevalence of LVH was 24% in KTx patients and 72% in PD patients (NS). KTx had significantly lower LVM, LVMi levels, E/A ratio, FS, and LA diameter compared  with the PD group, while the EF and other echocardiographic parameters did not differ. In the subgroup of 18 KTx, LVMi levels after transplantation were significantly lower than dialysis LVMi levels.

Conclusion: LVH is the most frequent cardiac abnormality at the time of kidney transplantation. After KTx, the reduction of LVH and diastolic dysfunction was significant. CV remodelling after successful KTx is related to better kidney function, and can explain better outcomes for patients with kidney transplants over patients on long-term dialysis.

Marker assisted back crossing is reliable tool in selecting the heterozygotes in backcross generations. It quickens the selection process which would otherwise require an extra generation/season for raising the BCF2 seed for finding the recessive allele which needs to be phenotypically expressed. Therefore in the present study normal maize (BML-6and IML-187) and QPM donor lines (DQL-2029-1 and DQL-779-2-9) were genotyped at o2 locus using co-dominant SSR marker phi057. The marker allele size at 02 locus for normal parents was 155 bp in IML-187(P1) and 160 bp in BML-6(P2). 170bp in DQL-2029-1(P3) and DQL-779-2-9(P4) for QPM or donor parents. Based on this polymorphism crosses were made to generate F1 hybrids. IML-87 was crossed with DQL-2029-1 and BML-6 was crossed with DQL-779-2-9. Thus, based on polymorphism at the DNA level, biparental backcrosses were made to eventually combine o2 allele in the endosperm of normal maize. The two BC1F1 populations were genotyped at the opaque-2 locus using phi057 SSR marker. It was observed that out of 96 plants analyzed, 40 individuals were heterozygous at o2 locus in BC1F1 population derived from the cross BC1F1 (A) while 43 out of the 100 plant analyzed in cross BC1F1 (B) were heterozygous when screened with phi057 SSR marker. Marker Assisted backcrossing is a useful tool in trait introgression as it helps in pre-flowering elimination of negative plants as well as donor genome and need for selfing is eliminated in BCF1 s. SSR phi-057 was able to clearly distinguish between QPM and normal parents and detect heterozygous plants in the backcross progeny.
