O principal objetivo deste trabalho foi estudar aspectos da biologia da polinização, comportamento e frequência de visitantes florais, reprodução e fenologia de Jacquemontia nodiflora em área de Caatinga hiperxerófila, em Petrolina-PE, no período de março de 2004 a março de 2005. Os dados fenológicos mostraram que a brotação, floração e frutificação concentram-se na estação chuvosa, enquanto a senescência foliar ocorre na estação seca, indicando a influência de precipitação no processo de reprodução. As flores estão reunidas em cimeiras, são pequenas (10 mm de diâmetro), curto-campanuladas, brancas, inodoras e secretam pequena quantidade de néctar (< 1 µl). A antese é diurna, ocorrendo por volta das 5 h 30 min., sendo o tempo de vida da flor apenas de nove horas. As flores são visitadas por abelhas, vespas e moscas, sendo as abelhas Apis mellifera, Trigona spinipes e Frieseomelitta doederleini os visitantes mais frequentes (47,7, 26,0 e 12,1% do total de visitas, respectivamente). Quanto ao sistema de reprodução, J. nodiflora é autógama facultativa, produzindo frutos por autopolinização (taxas > 90%) e por polinização cruzada (75,6%). Jacquemontia nodiflora pode ser considerada como uma importante fonte de néctar para abelhas de tamanho médio e pequeno, sendo A. mellifera, T. spinipes e F. doederleini consideradas como polinizadores desta espécie.

Published: February 2017

Background

Patients with hematologic malignancies are at risk for severe thrombocytopenia (sTP). The risk and benefit of aspirin are not known in thrombocytopenic cancer patients experiencing acute myocardial infarction (AMI).

Materials and Methods

Medical records of patients with hematologic malignancies diagnosed with AMI at Memorial Sloan Kettering Cancer Center during 2005–2014 were reviewed. sTP was defined as a platelet count <50,000 cells per µL within 7 days of AMI.

Results

Of 118 patients with hematologic malignancies who had AMI, 58 (49%) had sTP. Twenty-five patients (43%) with sTP received aspirin as a treatment for AMI. Compared with patients without sTP with AMI, patients with sTP with AMI were less likely to receive aspirin (83% vs. 43%; p = .0001) and thienopyridine treatment (27% vs. 3%; p = .0005). During median follow-up of 3.7 years after AMI, survival was lower in patients with sTP than in those with no sTP (23% vs. 50% at 1 year; log rank p = .003). Patients with sTP who received aspirin for AMI had improved survival compared with those who did not (92% vs. 70% at 7 days, 72% vs. 33% at 30 days, and 32% vs. 13% at 1 year; log rank p = .008). In multivariate regression models, aspirin use was associated with improved 30-day survival both in the overall patient cohort and in sTP patients. No fatal bleeding events occurred. Major bleeding was not associated with sTP or aspirin use.

Conclusion

Treatment of AMI with aspirin in patients with hematologic malignancies and sTP is associated with improved survival without increase in major bleeding.
Insights into Diabetic Kidney Disease Using Urinary Proteomics and Bioinformatics
Authors: Van Julie A.D. , Scholey James W. , Konvalinka Ana
Published: February 2017

A number of proteomic and peptidomic analyses of urine from diabetic subjects have been published in the quest for a biomarker that predicts progression of nephropathy. Less attention has been paid to the relationships between urinary proteins and the underlying biological processes revealed by the analyses. In this review, we focus on the biological processes identified by studying urinary proteins and protein-protein interactions at each stage of diabetic nephropathy to provide an overview of the events underlying progression of kidney disease reflected in the urine. In uncomplicated diabetes, proteomic/peptidomic analyses indicate that early activation of fibrotic pathways in the kidney occurs before the onset of microalbuminuria. In incipient nephropathy, when albumin excretion rates are abnormal, proteomic/peptidomic analyses suggest that changes in glomerular permselectivity and tubular reabsorption account, at least in part, for the proteins and peptides that appear in the urine. Finally, overt nephropathy is characterized by proteins involved in wound healing, ongoing fibrosis, and inflammation. These findings suggest that there is a spectrum of biological processes in the diabetic kidney and that assessing protein networks may be more informative than individual markers with respect to the stage of disease and the risk of progression.

Authors: Banach Mary , Rataj Alison , Volis Anthony
Published: February 2017

Teaching has often been cited as a mechanism to deepen and enhance knowledge acquisition. Teaching assistants, being simultaneously students and teachers, are in a unique position to facilitate their own learning. To date, there is a lack of research related to the vicarious learning process that results from teaching social work theory and clinical practices. This article presents the results of an exploratory study describing the reactions and perceived practice skill attainment of advanced undergraduate and graduate social work students who functioned as teaching assistants. Data were collected through surveys administered to the teaching assistants and include quantitative and qualitative results. Findings indicate that respondents valued the teaching experience because it enhanced clinical social work skill development and reinforced previously acquired knowledge related to the practice of social work. Implications for social work teaching are explored for social work undergraduate and graduate programs.

Published: February 2017

Maize is among the most preferred crop in Tanzania and other parts of the world. However, its production has been facing a number of challenges. Maize Lethal Necrosis Disease (MLND) is a new challenge in Eastern Africa. The control of MLND is said to be complicated as it is caused by a combination of more than one virus viz. Maize Chlorotic Mottle Virus (MCMV) and Sugarcane Mosaic Virus (SCMV). Stakeholders agree that the priority is to identify MLND resistant maize varieties. Genetic diversity provides the source of traits required against maize production challenges such as MLND. The study of genetic diversity in maize accessions often involves characterizing morphological plant characteristics as well as molecular marker techniques to study variation at DNA level. This review explores different literatures that address the importance of genetic diversity and the possibility of generating information towards obtaining potential materials against maize challenges and MLND in particular.

Authors: Afza Higa
Published: February 2017

Karakteristik padi beras merah yang memiliki umur dalam (lebih dari 134 hari) dan postur tanaman yang tinggi (rata-rata 164 cm) menyebabkan preferensi petani untuk membudidayakan padi beras merah cenderung menurun. Menurut hasil penelitian, beras merah mengandung antioksidan yang lebih tinggi dibandingkan dengan beras putih serta dianjurkan untuk diet gula. Saat ini hanya sebagian kecil plasma nutfah padi beras merah yang ditanam secara luas untuk memenuhi kebutuhan, khususnya kalangan masyarakat yang makin menyadari keutamaan kandungan gizi beras merah. Sementara sebagian besar plasma nutfah padi beras merah tidak ditanam secara terus-menerus sehingga akan mengalami erosi genetik. Oleh karena itu, Balai Besar Penelitian dan Pengembangan Bioteknologi dan Sumberdaya Genetik Pertanian sebagai lembaga yang memiliki mandat pelestarian tanaman pangan, terus mela-kukan konservasi ex-situ. Hingga kini 54 varietas/galur padi beras merah telah dikumpulkan melalui eksplorasi dari hampir seluruh daerah di Indonesia dan telah dikarakterisasi. Dengan adanya keragaman genetik padi beras merah yang berasal dari berbagai daerah di tanah air, diharapkan program pemuliaan tanaman dapat berjalan sesuai dengan tujuan.
Quantitative Evaluation of Key Geological Controls on Regional Eagle Ford Shale Production Using Spatial Statistics
Authors: Tian Yao , Ayers Walter B. , Sang Huiyan , McCain William D. , Ehlig-Economides Christine
Published: February 2017

Recent progress has increased our understanding of key controls on the productivity of shale reservoirs. The quantitative relations between regional Eagle Ford Shale production trends and geologic parameters were investigated to clarify which geologic parameters exercise dominant control on well production rates.

Previously, qualitative correlations for the Eagle Ford Shale were demonstrated among depth, thickness, total organic carbon (TOC), distribution of limestone beds, and average bed thickness with regional production. Eagle Ford production wells are horizontal, but it was necessary to use vertical wells that penetrated the Eagle Ford to map reservoir properties. No wells in the data base had both production and geological parameters, thus geological parameters could not be directly related to individual well production. Therefore, spatial interpolation methods based on kriging and Markov Chain Monte Carlo (MCMC) sampling algorithms were utilized to integrate data sets and predict geological properties at production well locations. The spatial Gaussian Process regression modeling was conducted to investigate the primary controls on production.

Results suggest that the 6-month cumulative production from the Eagle Ford Shale, in barrels-of-oil equivalent (BOE), increases consistently with (a) depth, (b) Eagle Ford thickness (up to 180-ft thickness), and (c) with TOC (up to 7%). Also, when the number of limestone beds exceeds 12, production increases with the number of limestone beds. The corresponding significance code indicates that the parameters most significant to production are TOC and depth (which relates to pressure).

Concepts and models developed in this study may assist operators in making critical Eagle Ford Shale development decisions and should be transferable to other shale plays
Fracturing Fluid Distribution in Shale Gas Reservoirs Due to Fracture Closure, Proppant Distribution and Gravity Segregation
Authors: Liu Yongzan , Leung Juliana Y. , Chalaturnyk Rick , Virues Claudio J.J.
Published: February 2017

Many stimulated shale gas wells experience surprisingly low fracturing fluid recoveries. Fracture closure, gravity segregation, fracture tortuosity, proppant distribution, and shut-in (soaking) time have been widely postulated to be the contributing factors. This study examines the impacts of these factors on fracturing fluid distribution using flow and geomechanical simulations. The results are analyzed to understand the circumstances under which fluid recovery might be beneficial or detrimental to well performance.

A series of 3D numerical models are constructed based on petrophysical parameters, fluid properties and operational constraints representative of Horn River shale gas reservoir. Hydraulic fracture is modeled explicitly in the computational domain. Complex partially-propped fracture geometry is computed using numerical constitutive models. The physical process of fracture closure during shut-in and production periods is modeled by adjusting the fracture volume and fracture conductivity dynamically. Non-Darcy behavior due to high gas velocity in fracture and matrix desorption are considered. The coupled effect of multi-phase flow, gravity and geomechanics is simulated to examine the mechanisms responsible for the low fracturing fluid recovery and the ensuing fluid distribution away from the wellbore. Water uptake into the matrix is influenced by forced and spontaneous imbibition due to the large pressure differential across the matrix-fracture interface and matrix capillarity. Additional water is displaced into the matrix as pressure depletes and fracture closes. Gravity segregation may lead to water accumulating near the bottom of a vertical planar fracture, but fracture tortuosity could limit the segregation and promote a more uniform fluid distribution. The influence of proppant distribution is far more complex: results of the geomechanical simulation confirm the formation of a residual opening above of the proppant pack in a partially-propped fracture. Despite gas production is often hampered by non-uniform proppant distribution, the residual opening offers a highly conductive flow path for gas, which is much more mobile than the water-based fracturing fluid; this further aggravates the phenomenon of gravity segregation. Extended shut-in time may enhance the initial gas rate, but lower late-time production is observed.

Analysis of the residual opening of a partially-propped fracture and its implications on production performance is novel. The results highlight the interactions between different mechanisms on fracturing fluid distribution in 3D. A few practical insights pertinent to the optimal operation strategy are explained.
Species Diversity and Abundance of Marine Crabs (Portunidae: Decapoda) from a Collapsible Crab Trap Fishery at Kung Krabaen Bay, Chanthaburi Province, Thailand
Authors: Chutapa Kunsook  , Pongchai Dumrongrojwatthana
Published: February 2017

The diversity and abundance of marine crabs from a collapsible crab trap fishery at Kung Krabaen Bay, Gulf of Thailand, were observed from August 2012 to June 2013 using 10 sampling stations. The results showed that there were seven families, 11 genera and 17 species (two anomuran and 15 brachyuran crabs). The two anomuran species were Clibanarius virescens (1,710 individuals) and Clibanarius infraspinatus (558 individuals). For brachyuran crabs, Portunidae was the most common family, including 10 species. The dominant species of brachyuran crabs included Thalamita crenata (897 individuals), Portunus pelagicus (806 individuals), Charybdis affinis (344 individuals), Scylla sp. (201 individuals), and Charybdis anisodon (100 individuals). The abundance of crabs was affected by the habitat type. Anomuran crabs had the highest abundance in Halodule pinifolia seagrass beds, whilst brachyurans had the highest abundance in Enhalus acoroides seagrass beds. The dominant brachyuran species were found in pelagic areas near the bay mouth, such as P. pelagicus, P. sanguinolentus, C. feriatus, C. helleri, C. natator, C. affinis, and M. hardwickii. Lastly, reforested mangroves were important habitats for Scylla tranquebarica and C. anisodon. Seasonal and physical factors influenced the abundance of some crabs, for example, the abundance of C. virescens was correlated with temperature, and the abundance of T. crenata was correlated with transparency depth. Our results revealed that Kung Krabaen Bay serves as the home to many marine crab species; however, our results also revealed that 49% of the harvested crabs (2,308 out of 4,694 individuals) were simply discarded and subsequently died. Moreover, our research noted that eight non-target species will become target species in the near future. Therefore, research on the reproductive biology of some marine crabs and an improved understanding of the importance of marine crabs by local fishermen are necessary to prevent biodiversity degradation and loss in this area.

The present study examines financial sustainability of NBFC-MFIs operating in Gujarat. It also examines association between dependent factor with independent determinants of financial sustainability i.e. DER, OER, WOR, YGP, and SE. The study’s finding leads to the conclusion that NBFC-MFIs in Gujarat are financially not sustainable though they are able to achieve desired OS but fail to achieve desired ROE. Further YGP, OER and WOR are the significant predictor variables in determining the financial sustainability of selected MFIs.
Effect of Capital Structure Determinants on Profitability: With Special Reference to Iron and Steel Sector Units of India
Authors: Gogia Neeraj
Published: February 2017

This paper is an attempt to study the capital structure of Indian Steel Industry and its major determinants. In this study, almost 50% of companies out of 22 sample size are bearing highly debt driven in their capital structure and it creates financial risk to the debt driven companies. Debt driven companies have obligation to pay interest irrespective of profit made or loss incurred by the firms. Hence we tried to find out which are the various factors significantly explaining the return on capital employed. For which we have considered four independent variables from early studies and employed correlation analysis, multiple regression analysis techniques and ANOVA in this study to test the dependency of the return on capital employed ratio on independent variables. The researcher found three variables such as debt equity ratio, operating profit ratio and interest coverage ratio respectively having significant impact on the return on capital employed to ratio of selected sample size of steel companies.

CARDIOPROTECTIVE EFFICACY OF TAURINE ON LIPID-METABOLISM OF ISOPROTERENOL-INDUCED MYOCARDIAL INFARCTION
Authors: Abdel-reheim Eman Salah
Published: February 2017

Objective: The present study aimed to evaluate the effect of pre-treatment with taurine on rats in which MI had been induced using isoproterenol (ISO).

Methods: Rats were randomly allocated into three groups; the 1st group is the normal control (C) one, the 2nd is the isoproterenol cardiotoxic (ISO) one and the 3rd group is the taurine pretreated (T-ISO) one.

Results: The activities of the cardiac biomarker enzymes, AST, LDH, CK and CK-MB were elevated in the ISO-treated group. The membrane-bound  Na+-K+ and Ca2+ ATPase enzyme activities were decreased in the ISO-treated group. The lipid profile either in sera or cardiac tissues was increased in ISO-treated rats except for HDL-cholesterol and phospholipids. The cholesterol ester synthetase (CES) activity was elevated, while lecithin: Cholesterol acyltransferase (LCAT) and lipoprotein lipase (LPL) activities were decreased in the myocardial infarcted rats. In addition, the high level of the troponins I and T was an indication of cardiac necrosis. Pre-treatment with Taurine, however, ameliorated all of these changes, in addition to its effect in improving the oxidation process, as measured by lipid peroxidation and the antioxidant enzymes, superoxide dismutase and peroxidase enzymes.

Conclusion: Taurine showed amelioration effects on the changes in lipid profile, oxidative stress and myocardial infarction biomarkers and therefore, can be protected against cardiotoxicity.

Methods: A C8 column (250 x 4.6 mm, 5 µm) was used as stationary phase, the mobile phase consisted of 0.1 M dipotassium hydrogen orthophosphate buffer (pH 6.0) and acetonitrile in a 50:50 (% v/v) ratio. The flow rate was set to 0.5 ml/min. UV detection of 210 nm was used for clarithromycin and 232 nm for spiramycin. Ambient column and sample tray temperatures were used.

Results: The method proved to be suitable for the detection of both macrolide antibiotics in bulk samples, as part of amorphous solid dispersions as well as in dosage forms. The isocratic elution was rapid. The method was validated in terms of system suitability, limits of detection (LOD), limit of quantification (LOQ), accuracy, precision, linearity, and specificity. This method showed linearity across the concentration range of 4.0–5000.0 µg/ml for both antibiotics.

Conclusion: The developed method showed to be a simple and sufficiently sensitive method for the detection and quantification of either clarithromycin or spiramycin from samples that might contain even very small quantities of the antibiotics.

Objective: The aim of the present study was to investigate the daily effect of pre and post treatment of carob aqueous extract (600 mg/kg b. wt.); on rats exposed to were exposed to water pipe smoke (10 mg/kg; 15 minutes) for 2, 4, 6 and 8 w.

Methods: Rats were divided into 6 groups; 1st group was served as a control. Rats of the 2nd group were administered amiodarone (an antiarrhythmic medication used as a model for lung toxicity) at a dose level of 30 mg/kg. The rats of 3rd and 4th groups were exposed to water pipe smoke and treated with carob extract respectively. However, the two remaining groups (5th and 6th) were the pre-and post-treatment groups with carob extract respectively.

Results: Amiodarone and water pipe smoke induced a significant increase in serum alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP); on the contrary, induced a significant decrease in serum total protein and albumin. In addition; serum creatinine and urea showed a significant increase; as well as; amiodarone and water pipe smoke increased the oxidative stress (malondialdehyde/glutathione; MDA/GSH) in lung tissue homogenate. While; carob extract gavage showed protective and curative effects in liver and kidney functions; in addition; it decreased MDA level and increased GSH level significantly.

Conclusion: Finally, we can conclude that the carob aqueous extract treatment revealed ameliorative effects on rats were exposed to water pipe smoke.

The elaboration of this study aimed to analyze the importance of the didactic book for the student's life and approach to the subject: Entomology in the series of 7th year (6th year) the Elementary School and 2nd year of high school adopted by the School Unit Joaquim Parente of Bom Jesus - Piauí. In order to make this work was done analyzes critical in the workbooks ofscience and biology on the topic of Entomology. The following topics were considered as the analysis: theoretical content, visuals, practical activities and information such as number of pagesand organization of subjects. Was verified that both workbooks have good visual aids. Regarding the organization of subjects, 7th year (6th year), presents a more easily understood by the student, because the study of insects is separated from other arthropods, which is not done in the workbook of 2nd year. The subjects of the 2nd year of approaches exists in general all arthropods as: the general characteristics, diversity, anatomy, physiology and reproduction of arthropods. Everyone is made in simultaneously in a comparative way. It is intended with this work, to contribute to the debate on the need for greater involvement of teachers in the process of choosing a workbook.
Critical issues on the enforcement of the “true and fair view” accounting principle: Learning from Parmalat
Authors: Melis Andrea
Published: February 2017

This paper analyses and discusses the “positive” issues of the overriding international financial reporting standards principle of “true and fair view” in connection with corporate governance mechanisms. The analysis is based on case study evidence. Empirical evidence from the Parmalat case with regards to the role of the information supply and demand side agents is analysed. This study provides evidence on how the relationship between corporate financial reporting and corporate governance mechanisms may influence the enforcement of the international financial reporting standards overriding principle of “true and fair view”. Evidence is found that the enforcement of the “true and fair view” principle is intrinsically flawed when the accountability and the overall corporate governance systems do not work properly. Some evidence is also found for the argument that a lack in the quality of information supplied by the corporate financial system hurdles the role information demand side agents as effective monitors.
Investors trust after parmalat scandal: The role of corporate governance
Authors: D’Orio Giovanni
Published: February 2017

The collapse of the Parmalat food empire reveals a troubling aspect about Italian capitalism - the lack of effective financial control over its family-owned companies. But was Parmalat scandal a pure problem of corporate governance or was it simply a “fraud”? Bearle and Means (1932 pg. 6) famously explained: “The separation of ownership from control produces a condition where the interests of owner and of ultimate manager may, and often do, diverge ....”. Is this the case? Were the people who invested in bonds and shares of Parmalat savers, investors or what? Which was the role played in the story by Auditors, CONSOB and Bank of Italy? This paper analyses the current situation of the Italian corporate governance and saving system in a critical view trying to find an explanation to the previous questions.

Published: February 2017

A new hybrid model of corporate governance seems to be emerging as a mixture of the shareholder and the stakeholder models. Its two main characteristics consist in an increased control of corporate executives by strong minority shareholders: this strengthened financial control is balanced by the rise of the social and environmental responsibilities of firms. This paper elaborates on this hypothesis and reviews the forces at work in this emerging process.
