title: PREPARATION AND CHARACTERIZATION OF NANOEMULSION CONTAINING A NATURAL NAPHTHOQUINONE

description: Natural naphthoquinones such as lapachol (Lp) have demonstrated promising biological activities. However, these quinones present low systemic biodisponibility due to its poor aqueous solubility. To overcome this problem, nanoemulsions (NE) formed by oily core are able to incorporate hydrophobic molecules thus enabling them to be dispersed into an aqueous phase. The present study reports the development, characterization, and physical stability of NE containing lapachol. NE formulations (F1, F2, F3, F4, and F2-Lp) were prepared using emulsion phase inversion (EPI) method and characterized in relation to droplet size, size distribution (PDI), zeta potential, and physical stability. The formulation chosen to incorporate lapachol (F2-Lp) showed droplet size in nanometric scale with homogeneous size distribution (PDI &lt; 0.2) and negative zeta potential (about −30 mV). In addition, good physical stability of F2 and F2-Lp was demonstrated using analytical centrifugation with photometric detection where the light transmission profiles did not change throughout the dispersions. Nanoemulsion containing lapachol presented a strong reddish aspect; however, the incorporation of this naphthoquinone did not alter the main physicochemical parameters of NE formulation. The in vitro release study demonstrated a sustained release profile from NE with about 60% of lapachol released within 54 h.

title: UATR and NIRA evaluation in the quantification of ATBC in NC blends

description: Abstract The paint industry requires rapid and accurate methodologies of raw materials qualitiy controls. For example, the evaluation of the suitable ratio of binary mixtures of polymer/plasticizer such as nitrocellulose (NC)/acetyl tributyl citrate (ATBC) must be done, since this ratio is directly related to the performance of the final product. However, there is a small number of quantitative methodologies of such control in the literature. In this context, in this paper, the applicability of Infrared Fourier Transform Spectroscopy (FT-IR) techniques by using universal total attenuated reflection (UATR), in the middle infrared (MIR), and the reflectance analysis in the near infrared region (NIRA) is evaluated for the quantification of plasticizer ATBC in mixtures with NC. MIR and NIR methodologies presented good results such as: practicality of not requiring refined sample preparation, analysis time about 30 min and good accuracy, suitable data for using in the quality control laboratories of paint industry.

title: Haematological reference of snakes: Amazon tree boa (Corallus hortulanus, Linnaeus, 1758) and Burmenese Python (Python bivittatus, Kuhl, 1820) in captive

description: ABSTRACT Hematology has become important for making clinical diagnoses in snakes because maintenance techniques in captivity have been improving and increasing their life expectancy. The emergence of diseases in captivity requires the creation of parameters to understand the species in their healthy state. The possible association between the onset of neoplasia, immunosuppression, and viral infection are also important factors to consider. Thus, hematology is a fundamental tool for observing the responses of animals to diseases and treatments. The present study aims to study hematology between two species of snakes and compare the profiles observed with published results. Blood samples were collected from 16 male and female snakes: seven Corallus hortulanus from the family Boidae and nine Python bivittatus from the family Pythonidae belonging to the Biological Museum of the Butantan Institute, São Paulo, Brazil. Complete blood count results including blood smear, total erythrocyte count, leukocytes, and differential leukocyte count were evaluated. The data obtained in this study could help with the diagnosis, the treatment of snakes in captive conditions and in of nature conservation programs.

title: Health promotion programs in higher education: integrative review of the literature

description: ABSTRACT Objective: to characterize the interventions of health promotion programs implemented in Health Promoting Universities; to analyze the results of the interventions of health promotion programs. Method: integrative review carried out in EBSCO, PubMed, SciELO, Scopus and Web of Science. Articles published between 2000 and 2014 were selected, with evidence of health promotion intervention programs and evaluation of results. Results: 17 articles were included. The health promotion programs aimed at increasing the welfare of students, with an emphasis on physical activity, sexual health and on improving the environment of health support within the university community. Conclusion: health promotion strategies in an university context do not always result from the convergence between educational, political, legislative or organizational actions that support lifestyles and conditions which are favorable to the health of individuals or groups, and that contribute to improving the physical and social environment.

title: Reliability of screening tests for health-related problems among low-income elderly

description: Screening tests for health problems can identify elderly people who should undergo the Comprehensive Geriatric Assessment, enabling the planning of actions to prevent disability. The aim of this study was to analyze the inter-rater reliability (IRR) of self-assessment questions (SAQ) and performance tests (PT) recommended in Brazil, in a sample of low-income elderly people, through an exploratory study performed with 165 elderly assessed by two professionals on different days. IRR was evaluated using the intraclass correlation coefficient (ICC) for continuous variables and the kappa statistic for categorical ones. The IRR for the PT (muscle strength, mobility body mass index, vision) was excellent and presented ICC values greater than 0.75. By contrast, the IRR for SAQ (urinary incontinence, self-perceived health and hearing impairment) was intermediate. Only the fall-related item presented a good IRR. In this study single SAQ had poor reliability when compared to PT, suggesting the necessity of revision of subjective self-assessment items with low reproducibility before implementation.

title: Babesia spp. in the peritoneal fluid in dog with ascites - case report

description: ABSTRACT Babesia canis is a cosmopolitan protozoan that parasites erythrocytes of domestic and wild dogs. The diagnosis is performed by direct observation of the microorganism in red blood cells in the peripheral blood smear, serological methods and molecular techniques. The aim of this work is to report for the first time the presence of merozoites of Babesia spp. in the peritoneal fluid of a dog with ascites. At the Veterinary Hospital of the Federal University of Viçosa was attended a Mixed-breed seven month old dog, male, with history of emaciation, apathy and abdominal bulging. Pale mucous membranes, ascites, grade IV/V systolic murmur and tachypnea were evidenced in the physical examination. Laboratory tests revealed normocytic/normochromic anemia, thrombocytopenia, and hypoproteinemia. Intra-erythrocyte structures compatible with Babesia spp. were observed in the blood smear. The evaluation of the ascites fluid was compatible with modified transudate where numerous intra and extracellular structures compatible with Babesia spp. merozoites were observed. The presence of intra and extracellular microorganisms could be related to an injury of the spleen with extravasation of the contents into the abdominal cavity. Collection of the peritoneal fluid may be an alternative for the diagnosis of babesiosis when the animal with suspected infection has ascites.

title: “UFSCar” Index of Effectiveness applied to the Food Purchase Program for food and nutritional safety of farming families in the hinterland of São Paulo state

description: Abstract This work aims to develop an index to evaluate the effectiveness of Brazil’s Food Purchase Program (FPP), using the perspective of food and nutritional safety (FNS) for farming families in the settlement territory of Araraquara, São Paulo, as analytical reference. To develop the index, we selected analytical variables with theoretical and methodological adherence to the concepts of FNS, FPP, and family agriculture (FA),using the statistical method of orthogonal factor rotation (Varimax). The theoretical framework—neo-institutionalism—was used to discuss the public policies for food safety, and create an analysis based on effort, reciprocity, and confidence in the construction of networks through the FPP. The level of food (in)security was evaluated by the UFSCar Index of Food Safety for family farmers. Data show that 73% of farmers who regularly access the FPP have moderate or high rates of FNS, while 93% of those who do not access the program have a moderate or low FNS index. This shows that despite institutional efforts, food unsafety is still present and must continue to be addressed in the public policy agenda.

title: Moment of inertia through scaling and the parallel axis theorem

description: Abstract A right triangular plate scaled by a factor two generates a bigger plate composed of four triangular plates the same size as the original. By using dimensional analysis we write the moment of inertia around the center of mass, for the original and the bigger plate, in terms of a common unknown parameter. Through the parallel axis theorem we relate the moments of inertia of both plates and finally solve a very simple equation to find out the unknown parameter. This procedure avoids to calculate integrals. The result is extended to a scalene triangular plate by recognizing it is composed of two right triangular plates. We also review the parallel axis theorem in an appendix.

title: Guar root and shoot growth as affected by soil compaction

description: ABSTRACT Guar (Cyamopsis tetragonoloba L.) is commonly grown in arid lands, because of its high drought-tolerance. However, soil compaction may be a limiting factor to its growth. This study aimed to evaluate the guar growth, according to the soil penetration resistance (0.20 MPa, 0.33 MPa, 0.50 MPa, 0.93 MPa and 1.77 MPa, in a layer with depth between 0.15 m and 0.20 m), in a Rhodic Acrudox soil. The shoot and root dry mass, root length by the Q1/2 index (mechanical soil penetration resistance in which the root growth is reduced by 50 %) and root diameter were evaluated. The impairment of the guar shoot growth begins when the penetration resistance is greater than around 1 MPa. The soil compaction alters the distribution of guar roots in the soil profile, concentrating them in the 0.15 m layer, but it does not prevent roots from penetrating this layer and developing in depth. The root diameter increases in the compacted layer. A soil penetration resistance of up to 1.77 MPa does not influence the root length density below the compacted layer, as well as the total root length density of guar. Although the guar Q1/2 index is greater than 1.58, the shoot and root dry mass are impaired.

title: Genetic variability of twelve microsatellite loci in native Canela-Preta chickens

description: ABSTRACT The aim of this study was to analyze the genetic variability of twelve microsatellite loci in native Canela-Preta chickens. Blood samples were collected from 118 chickens of the breed from five properties in three cities (Oeiras, Queimada Nova and Teresina) of Piauí state. After the DNA extraction, markers were used for twelve microsatellite loci: LEI0192, LEI0209, LEI0212, LEI0217, LEI0221, LEI0234, LEI0237, LEI0248, LEI0258, MCW0081, MCW0183, and MCW0213 that were amplified by polymerase chain reaction technique (PCR). The results showed a total of 408 alleles (adding alleles from the 12 loci) with the fragments ranging between 50 and 460 base pairs, the number of alleles ranged from 15 (MCW0081) to 52 (LEI0212) with an average of 31,5 alleles per locus. The average expected heterozygosity and PIC were, respectively, 0.887 and 0.909. Deviations were observed in the Hardy-Weinberg equilibrium and positive values of the fixation index with excess of homozygotes. It is concluded that the used microsatellites are polymorphic and can, therefore, be used for genetic research in Canela-Preta chickens. The birds of the analyzed cores present great genetic variability, which qualifies them as an important source of genetic resources, which could be used for future animal breeding programs.
