Authors: Guan Yi , Wang Su-Rong , Huang Xin-Zhong , Xie Qiong-hong , Xu Yun-Yu , Shang Da , Hao Chuan-Ming
Published: March 2017

The rapid growth of an aging population creates challenges regarding age-related diseases, including AKI, for which both the prevalence and death rate increase with age. The molecular mechanism by which the aged kidney becomes more susceptible to acute injury has not been completely elucidated. In this study, we found that, compared with the kidneys of 3-month-old mice, the kidneys of 20-month-old mice expressed reduced levels of the renal protective molecule sirtuin 1 (SIRT1) and its cofactor NAD+. Supplementation with nicotinamide mononucleotide (NMN), an NAD+ precursor, restored renal SIRT1 activity and NAD+ content in 20-month-old mice and further increased both in 3-month-old mice. Moreover, supplementation with NMN significantly protected mice in both age groups from cisplatin-induced AKI. SIRT1 deficiency blunted the protective effect of NMN, and microarray data revealed that c-Jun N-terminal kinase (JNK) signaling activation associated with renal injury in SIRT1 heterozygotes. In vitro, SIRT1 attenuated the stress response by modulating the JNK signaling pathway, probably via the deacetylation of a JNK phosphatase, DUSP16. Taken together, our findings reveal SIRT1 as a crucial mediator in the renal aging process. Furthermore, manipulation of SIRT1 activity by NMN seems to be a potential pharmaceutical intervention for AKI that could contribute to the precise treatment of aged patients with AKI.

In any retail business, the key to success is to tear down the barriers between you and the customer. In this case, the barrier exists between our records of transactions and information about our customers. This is the barrier between big data, with thousands of records, and information. To remove this, we needed to collect our data and group our customers into manageable portions on which we could make business decisions. We took our information, formatted it, aggregated it, and clustered it into 5 groups with distinct characteristics. We could make relevant decisions for each customer with minimal effort, even though we had hundreds of customers to analyze.

Operational Characterization of a Combined Electrolysis Catalytic Exchange Process
Authors: Ng Kelvin
Published: March 2017

Many current CECE systems, which are used to extract harmful tritium from heavy water nuclear reactors, operate with inefficient alkaline electrolyzers that contain dangerous caustic chemicals. Thus the Hydrogen Isotope Branch at Chalk River Laboratories developed and integrated a safer and more efficient PEM electrolyzer to replace the alkaline electrolyzer. In this research, a bench-scale CECE system with a PEM type electrolyzer at Chalk River Laboratories was tested at LPCE column temperatures of 20°C, 40°C and 60°C to determine baseline operational parameters and conditions for optimal isotopic exchange. Increased operational temperature led to greater isotopic exchange across the PEM electrolyzer but not the LPCE column, an irregularity likely caused by an insufficient amount of catalyst in the column. Increased LPCE temperature also led to a decrease in overall system flow stability. Finally, the PEM electrolyzer voltage exhibited an unusual sharp rise throughout testing, indicating the membrane's susceptibility to damage if used without proper conditioning. Research conclusions will be taken into consideration in setting up a new bench-scale CECE process that more accurately models tritium extraction using a PEM electrolyzer.
Preventing Favism by Selecting Faba Bean Mutants Using Molecular Markers
Authors: Song Melody
Published: March 2017

Faba bean (Vicia faba) is an ancient legume species known for its high protein content. The usage and consumption of the faba bean is limited by a glycoside, vicine-convicine (VC). Consumption of VC causes haemolytic anemia in individuals with the genetic condition called favism. Faba beans with low VC concentration are opening the possibility of reduction of favism disease, but there are many challenges in analyzing VC concentration. The objective of this study was to develop expressed sequence tag (EST) markers that can differentiate between low VC content (LVC) and high VC content (HVC) faba bean genotypes. Three single nucleotide polymorphisms (SNPs) were discovered that distinguished between LVC and HVC genotypes. The SNPs were validated using Kompetitive Allele Specific PCR (KASP) and mass spectrometry phenotyping. Molecular marker SNP 316 (Intron of Medtr2g009270 at 1,851,012 bp) was the most successful marker in differentiating between LVC, HVC, and heterozygous faba bean genotypes. This marker has applications in seed selection and acceleration of breeding programs, which is the first step towards allowing all consumers concerned with the effects of favism to enjoy the nutritional value of faba bean.

Published: March 2017

The process of programmed and physiological cell death, or apoptosis, is generally characterized by distinct morphological characteristics and energy-dependent biochemical mechanisms. Apoptosis normally removes old, damaged, excessive and harmful cells and is essential for tissue homeostasis. Cancer is a disease in which damaged cells do go through apoptosis and ultimately uncontrolled cell division results in the formation of a malignant tumor. Stomach cancer is the most common cancer in Iran with about 7751 affected in the year of 1387. This is about 10.17% of the total male and female population per year. Unfortunately, existing treatment options are often aggressive with harmful side effects for the patient. In this study, we decided to prepare anti-cancer drugs from natural ingredients such as eggplant skin which is rich in antioxidants. The primary hypothesis of this study was that due to the presence of compounds containing antioxidants in eggplant skin, the extract should be able to destroy cancer cells by activating their apoptosis. This hypothesis was examined by MTT colorimetric method in two series of cells: gastric cancer cells (AGS) and normal fibroblasts cells (FIB). The yellow MTT salt becomes an insoluble purple formazan by dehydrogenase enzymes in the active mitochondria of cells. The results of this study show that eggplant skin extracts in concentrations of 2.5 μM have a high cytotoxic effect on gastric cancer cell lines, which could be due to the induction of apoptosis in these cells and the least effect on normal fibroblasts cells. Therefore, eggplant skin extract has a positive effect on the apoptosis of cancer cells and can be used in the production of stomach cancer drugs.
Ultra-Hydrophobic Water
Authors: Sedigh Rozhina
Published: March 2017

When a drop of a viscous fluid is deposited on a bath of the same fluid that is vibrating, it is shown that it coalesces with this substrate or lifts off when the vibration of the surface is larger than g, leading to a steady condition where a drop can be kept bouncing for any length of time, as shown in figure 1. The phenomena that will occur depends on various parameters, such as drop impact acceleration, liquid surface tension, density, dynamic viscosity, gravity, droplet radius and impact speed, bath vibration frequency and amplitude. The effect of different parameters will conclude to a set of conditions which results in a system, called “ultra-hydrophobic water” which plays important role in chemical micro fluidic applications.

Published: March 2017

Background: Pre-renal failure, a reversible form of acute renal failure (ARF), accounts for 60-70% of all cases of ARF. To study the factors affecting fractional excretion of sodium (FENa) in patients with pre-renal failure.Methods: The study involved patients with pre-renal failure, admitted in a multi-speciality hospital in south India for a period of two years. The demographic and clinical data were collected using a standard pro forma. The correlation between FENa and factors such as age, diabetes mellitus, fluid loss, fever, urine output and creatinine of pre-renal failure were statistically evaluated.Results: The prospective study involved 24 patients diagnosed as pre-renal failure with a mean age of 52.75±18.78. The subjects included 14 males and 10 females, with a median FENa of 0.55 (0.10-0.90). A moderate negative correlation was observed between FENa and fluid loss in pre-renal failure patients (r -0.646, P=0.0007).Conclusions: The level of FENa may assist in estimating fluid loss in patients with pre-renal failure.

Оценка опережающего развития финансового сектора
Authors: Данилов Юрий Алексеевич
Published: March 2017

В настоящей статье представлены результаты исследования оценки опережающего развития финансового сектора по сравнению с общеэкономической динамикой. На основе методики оценки финансового развития, разработанной Всемирным банком и Международным валютным фондом, автором были сделаны дополнения, позволяющие оценить относительную скорость этого развития и вовлечь в анализ российский финансовый сектор. Сохранявшаяся в течение нескольких десятилетий тенденция к опережающему росту финансового сектора в глобальном масштабе была прервана кризисом 2008 года. При этом после 2008 года в России наблюдалось сильное падение во всех сегментах финансового сектора, кроме банковского сегмента, развитие которого продолжало опережать общеэкономическую динамику. Это привело к формированию структурных деформаций российского финансового сектора и снижению его глобальной конкурентоспособности.

Methodology: Survey of utilization of garbage at international level with special reference to Pimpri Chinchwad area of Pune

Findings:  Garbage can is utilized for making manure, vermin compost, generating electricity, etc.

Social/ Academic Implications: Clean India Green India

Originality/Novelty of article:  Recycling of all types of garbage for fruitful utilization.

The beginning of civilization led to development around river banks. Things could be managed during those days as people lived in harmony with nature. The scenario changed with industrialization which started creating havoc at the end of 19th century when the industrial revolution took the world of the consumer by leaps and bounds, which led to the concentration of population packets in and around the industrial areas. This rapid change in the development brought forth many challenges before the planning authorities especially the provision of basic amenities and hygienic place of living. The biggest challenge before the administration was and is to manage the waste generated by this large population. The solid waste generation has become a continuous global problem at all levels throughout the world. [1]

Epileptic Seizures Versus Syncope: Pathophysiology and Clinical Approach
Authors: Charalambous Marios , Gomes Sergio A. , Papageorgiou Stella , Orioles Massimo
Published: March 2017

Generalised epileptic seizures and syncope are two syndromes with similar clinical manifestation and their differentiation can be quite challenging. The aim of this review is to use an evidence-based approach in differentiating these two syndromes through the comprehension of the pathophysiological mechanisms involved and their clinical signs. Both syndromes affect regions of the forebrain and consciousness level, although, different mechanisms are involved. Syncope is a paroxysmal event secondary to a short-term decrease in cerebral perfusion, oxygenation or essential nutrients delivery. Generalised epileptic seizure activity is defined as the clinical manifestation of transient paroxysmal disturbances in brain function secondary to an imbalance between excitatory and inhibitory neurotransmitters. Clinical criteria, including precipitating events, clinical signs preceding, during and following the episodes and event duration, can be used to differentiate the two syndromes. Although these criteria might be useful for the practitioner, definite conclusions should be precluded due to the lack of original research articles and weak evidence on this specific field.

Application: The review might be a useful tool for the general practitioner and clinical scientist as it will aid towards the differentiation of two syndromes, i.e. generalised epileptic seizures and syncope, with similar clinical presentation.

Превођење у целини, а консекутивно превођење нарочито, представљају и поступак и производ који зависи од језичке компетенције преводиоца у оквиру система најмање два језика, а заснива се на свеобухватном знању, које преводилац има о речима, фразама и реченицама у та два језика. Циљ овог рада није да оспори или подржи ову тврдњу, већ да испита потребу да консекутивац прошири поменуту језичку компетенцију и усвоји вештине лингвистичке анализе која превазилази ниво речи, фраза и реченица, то јест залази у домен текста и дискурса. С обзиром на то да се и тексту и дискурсу у оквиру опште лингвистике већ приписује суштински значај, требало би сагледати и њихову везу са консекутивним превођењем. Препознавање прагматички кохерентних модела који се користе у језику и говору, као и одговарајућа анализа истих, могу омогућити предвиђање нових модела и тиме помоћи консекутивцу да превод одређеног дискурса обави брже, кохерентније и прецизније. Стога и основни циљ овог рада, да нагласи значај обуке консекутивних преводилаца у примени анализе дискурса у области консекутивног превођења. У ту сврху биће приказане неке кључне стратегије у обуци консекутиваца које могу унапредити ту вештину. Иако би имплементација ових стратегија била далеко ефективнија уколико би се интегрисала у курс са јасном структуром и дефинисаним методичким приступом, оне се могу користити и појединачно у сврху вежбања.

Published: March 2017

The paper investigated perceived organizational justice and leadership styles as predictors of employee engagement in the organization. The population comprised secondary school teachers from five secondary schools that were selected and a sample size of 130 respondents were drawn. Simple random sampling was used to select the respondents. The paper employed both primary and secondary data sources. The primary data was collected using self-administered questionnaire. The structured questionnaire was culled from three different instruments namely, Multi-factor Leadership Questionnaire, Organizational justice Scale and Utrecht work engagement scale. The data analysis methods used include descriptive statistics, ANOVA tests and regression analysis tests. The findings revealed that perceived organizational justice significantly predicts employee engagement and also perceived leadership styles predict employee engagement among secondary school teachers in Awka South local government area of Anambra state, Nigeria. The paper recommended that employers should ensure that; they reach out to every employee, thereby improving interpersonal relationship and fairness to note and attend to their organizational needs. This will make them feel at home with the organization, and at the same time the employee’s morale will be high enough to improve their engagement to the organization.

Published: March 2017

A Melissa officinalis L. (Lamiaceae) apresenta altos níveis de compostos fenólicos que apresentam entre outros efeitos biológicos a atividade anti-inflamatória, inibindo a atividade da ciclooxigenase e a inibição do citocromo P450. Devido seus efeitos biológicos tem ganhado espaço de destaque em diversos estudos. Os compostos fenólicos amplamente presentes nos vegetais formam-se constituintes da nossa alimentação, destacando-se chás e as cápsulas de fitoterápicos. O objetivo do presente estudo foi comparar a diferença de disponibilidade de moléculas ativas provenientes de plantas medicinais em duas diferentes formas de uso, cápsulas e chá.  Após simulação in vitro da digestão gástrica os compostos fenólicos totais foram determinados empregando-se o método espectrofotométrico de Folin-Ciocalteau. Obtivemos valores maiores de teor de fenóis totais na digestão das cápsulas do que nos chás de Melissa officinalis. Indicando que provavelmente as cápsulas apresentam maior disponibilidade de princípios ativos que as infusões. Vale ressaltar a necessidade de mais estudos para a comparação do teor de fenóis totais das infusões de Melissa officinalis, além de uso de outras plantas para verificar a melhor forma de uso das plantas medicinais.
CARACTERÍSTICAS DA POSSE E USO DE TERRAS RELACIONADAS ÁS CULTURAS AGRÍCOLAS DESTINADAS A PRODUÇÃO DE AGROENERGIA NO BRASIL (Biodiesel e Etanol)

Published: March 2017

Dentro da agroenergia os dois produtos que mais se destacam são: o biodiesel e o etanol. Sendo que este último já possui mercado e tecnologia consolidada, enquanto que o biodiesel ainda está em desenvolvimento e tenta se consolidar com apoio do governo. O uso destes tem como principal característica as vantagens ambientais, em relação ao uso dos combustíveis fósseis. Para o uso do biodiesel não é necessária alteração do motor a Diesel e colaborou para o sucesso do uso do etanol a tecnologia flex fuel. Este estudo analisou as características da posse e uso terra relacionadas a produção de matérias primas destinadas a produção do biodiesel e do etanol no Brasil. O processo metodológico utilizado foi ao descritivo, exploratório e bibliográfica. Em relação a utilização de terras para plantação da matéria prima para estes dois combustíveis, verificou-se que dado a quantidade de terras aráveis que o Brasil tem, a porcentagens destinada a produção de agricultura para produção de energia não afeta a produção de alimentos. Outra observação é que no caso da produção de biodiesel a principal matéria prima utilizada é o resíduo da soja, portanto, na maioria das vezes, esta não é plantada exclusivamente para a produção do mesmo.

RESUMO

Nossa proposta investigou e historicisou o conflito que ocorreu entre as forças de segurança do Estado do Pará e os trabalhadores rurais, ocorrido no dia 17 de Abril de 1996 na cidade de Eldorado do Carajás, onde, mais uma vez, no que se refere ás questões sociais vinculadas aos trabalhadores rurais e sua luta pela terra, o uso da violência prevaleceu como “solução” encontrada pelo mando político de caráter oligárquico, quase um “poder paralelo” a um poder judicial frágil, mantidos pelo uso da força, neste quadro ocorre o Massacre de Eldorado do Carajás, que culminou com a morte de 19 trabalhadores. Procuramos desvelar os sentidos diversiﬁcados das narrativas sobre o episódio dependendo de quem narra essas memórias: os sobreviventes, agentes pastorais, padres, intelectuais, policiais, jornalistas no sentido de desvelar os signiﬁcados que se atrelam a interesses especíﬁcos dependendo da inserção desses sujeitos diversiﬁcados no campo da memória, uma memória que é reativada, por vários enunciados, dentre eles os literários, pois é um meio que as vítimas acharam para expressar sua dor e sofrimento. Nesse sentido nossa pesquisa se propõe a levantar e problematizar as fontes disponíveis na CPT-Xinguara - PA dando ênfase á analise das narrativas de memória.

The research aims to evaluate calsium soap protection as feed supplement based on dry matter
digestibility, organic matter digestibility and pH in vitro in the rumen and post rumen. Calsium soap
was produced from sardine fish oil and soybean meal, through two protection methods. It was
saponification and microencapsulation. This research used Split Subject Repeated Measurement
Design with 3 treatments (calcium soap, soybean meal and pangola grass) which each treatment was
repeated 5 times. The observation kinetics of dry matter digestibility, organic matter digestibility, and
pH rumen fluid were done in incubation times (2, 4, 8, 12, 24 and 48 hours respectively). The first
results of the research showed that in the first step (rumen) has dry matter digestibility of calcium
soaps: 38.65; 40.00; 42.66; 46.32; 54.40 and 51.40% respectively; organic matter digestibility: 39.44;
41.27; 44, 31; 46.32; 56.62 and 52.50% respectively. Kinetics of pH rumen fluid: 6.89; 6.79; 6.78;
6.74; 6.71, and 6.88 respectively. In the second step (post rumen), the digestibility of calsium soap
production has dry matter digestibility of 74.85% and organic matter of digestibilty of 72.94%. The
results could be concluded that in the rumen, calcium soap is the most microbial degradation resistant
compared the others and it can be degraded and digested in the abomasum to the small intestine.
Therefore pH of rumen fluid is optimal, so it does not interfere with the fermentation in the rumen.

The study aimed to determine content of heavy metals Pb and Hg in the organic waste and method to eliminate the heavy metal residue of Pb from beef cattle products, meat and visceral organs. Two male Ongole Crossbred cattles were used in this study. Rations were given in the form of King Grass forage and commercial concentrate of Nutrifeed. The animals were kept for 3 months. At the beginning of the experiment, the fecal and blood samples were collected, then these samples were taken every two weeks. At the end of the experiment, the animals were slaughtered and meat samples of bicept femoris, liver, kidneys and intestines were taken to analyze its Pb content. The results showed that the organic waste contaminated with Pb, but not contaminated with Hg. Pb levels in blood and feces varied and quite high, whereas in beef products, meat and viscera the Pb were quite high and still above the safe limit for consumption. The conclusions of this experiment were that the conventional maintenance for three months after removed from the landfill was not able to eliminate the Pb content in products of beef cattle.
