title: Effect of compatibiliser on the properties of polypropylene/glass fibre/nanoclay composites

description: Abstract Glass fibre (GF), nanoclay (NC) and hybrid composites compatibilised with maleic anhydride polypropylene (MAPP) were prepared by extrusion and injection moulding. The fourier transform infra-red spectra revealed the characteristic absorption peaks of MAPP in the compatibilised GF and NC composites. A decrement in the peak intensity of X-ray diffraction patterns of NC composite was obtained as the MAPP content increased indicating a partial exfoliation of NC. The thermogravimetric analysis showed that the incorporation of MAPP into hybrid composites reduced the thermal stability of the material. The dynamic mechanical analysis showed an increase in the storage modulus in the hybrid composites with lower content of MAPP due to the enhancement in the interfacial adhesion between the GF, NC and PP matrix.

title: Family health strategy: relevance to the functional capacity of older people

description: ABSTRACT Objective: to identify the functional capacity of older people based on their performance on basic activities of daily living. Method: a cross-sectional study, carried out through the record of the Family Health teams working in the urban area of a city in northern Minas Gerais, in 2015. To assess the functional capacity of 373 older people, the Katz Scale was applied, which includes dimensions on the performance of daily living activities. The interviews took place in the participants’ households. Results: of the total participants, 6.9% had some degree of dependence. Those aged over 80 years old and were living without a partner had about three times more chances of presenting higher levels of functional dependence. Conclusion: most older people enrolled in a Family Health Strategy had their functional capacity preserved.

title: Self-perceived health and clinical-functional vulnerability of the elderly in Belo Horizonte/Minas Gerais

description: ABSTRACT Objective: To determine the self-perceived health status and clinical-functional vulnerability of the elderly attended at a Reference Center of Minas Gerais, Brazil and to evaluate the association between these variables through the Clinical-Functional Vulnerability Index (IVCF-20) instrument. Method: This is an epidemiological, retrospective study of 311 medical records. Statistical analyses were performed using the Stata program; the evaluations were by Pearson’s Chi-square test and Poisson regression models. Results: The majority of the elderly presented negative self-perceived health status(70.10%); there was statistical significance between negative self-perceived health and the variables of mood and recent hospitalization. Conclusion: Perceived health status influences the morbidity and mortality of the elderly. Mood disorders and recent hospitalizations directly interfere with active aging.

title: Factors associated to the dependence of older adults with diabetes mellitus type 2

description: ABSTRACT Objective: to identify factors associated to the dependence of older adults with Diabetes Mellitus, Type 2 Method: analytical and epidemiological study with 99 older adults. The Brazilian Multidimensional Functional Assessment Questionnaire and a questionnaire composed by socio-demographic and clinical variables were used. The independent variables were described and compared to the level of dependence obtained by the chi-square test or the Fisher test, the strength of association was estimated by Odds Ratio and multiple regression. Results: the level of dependence prevailed in 79.8% of the sample. Higher chances of dependence were associated to: cutting toenails; performing household chores; presenting geriatric problems; urinary incontinence; time of diagnosis of diabetes; falls in the past year; and physical inactivity. Conclusion: considering the positive association of diabetes mellitus to the increased chance of dependence among older adults, there is need for direction and adoption of effective measures to ensure the functionality and quality of life of older adults with diabetes mellitus in a fair and democratic way.

title: Non-invasive messenger RNA transcriptional evaluation in human kidney allograft dysfunction

description: The aim of the present study was to evaluate messenger RNA expression in kidney allograft recipients. Forty-four kidney transplant recipients were evaluated up to three months after grafting. After transplantation, peripheral blood samples were drawn sequentially for real-time polymerase chain reaction analyses of perforin and TIM-3 genes. Biopsies were obtained to evaluate acute graft dysfunction and interpreted according to the Banff classification. Eight patients presented episodes of acute rejection. Recipients with rejection had significantly higher levels of TIM-3 mRNA transcripts compared to those without rejection (median gene expression 191.2 and 36.9 mRNA relative units, respectively; P&lt;0.0001). Also, perforin gene expression was higher in patients with rejection (median gene expression 362.0 and 52.8 mRNA relative units; P&lt;0.001). Receiver operating characteristic curves showed that the area under the curve (AUC) for the TIM-3 gene was 0.749 (95%CI: 0.670–0.827). Perforin gene mRNA expression provided an AUC of 0.699 (95%CI: 0.599 to 0.799). Overall accuracy of gene expression was 67.9% for the TIM-3 gene and 63.6% for the perforin gene. Combined accuracy was 76.8%. Negative predictive values were 95.3% for the TIM-3 gene, 95.5% for the perforin gene, and 95.4% in the combined analyses. Gene expression was significantly modulated by rejection treatment decreasing 64.1% (TIM-3) and 90.9% (perforin) compared to the median of pre-rejection samples. In conclusion, the longitudinal approach showed that gene profiling evaluation might be useful in ruling out the diagnosis of acute rejection and perhaps evaluating the efficacy of treatment.

title: Solubility, porosity and fluid uptake of calcium silicate-based cements

description: Abstract Objective: To evaluate the absorption/fluid uptake, solubility and porosity of White mineral trioxide aggregate (MTA) Angelus, Biodentine (BIO), and zinc oxide-eugenol (ZOE). Material and Methods: Solubility was evaluated after immersion in distilled water for 7 and 30 days. Porosity was evaluated using digital inverted microscope, scanning electron microscope (SEM) and micro-computed tomography (micro-CT). For the fluid uptake test, specimens were immersed in Hank's balanced salt solution (HBSS) for 1, 7, 14 and 28 days. Fluid absorption, solubility and porosity of the materials were measured after each period. Statistical evaluation was performed using one-way analysis of variance (ANOVA) and Tukey tests, with a significance level at 5%. Results: After 7 and 30 days, BIO showed the highest solubility (p&lt;0.05). All methods demonstrated that MTA had total porosity higher than BIO and ZOE (p&lt;0.05). Micro-CT analysis showed that MTA had the highest porosity at the initial period, after its setting time (p&lt;0.05). After 7 and 30 days, ZOE had porosity lower than MTA and BIO (p&lt;0.05). Absorption was similar among the materials (p&gt;0.05), and higher fluid uptake and solubility were observed for MTA in the fluid uptake test (p&lt;0.05). Conclusions: BIO had the highest solubility in the conventional test and MTA had higher porosity and fluid uptake. ZOE had lower values of solubility, porosity and fluid uptake. Solubility, porosity and fluid uptake are related, and the tests used provided complementary data.

title: Viability of liquid medium-inoculation of Rhizobium etli in planting furrows with common bean

description: Abstract: The objective of this work was to evaluate the viability of liquid medium inoculation of Rhizobium etli in the planting furrow and to certify the efficiency of its strain UFLA 02-100 as a potential inoculant for common bean (Phaseolus vulgaris). The treatments consisted of three application rates of liquid inoculant applied in the planting furrows or in common bean seed, besides two controls without inoculation. The inoculant contained 109 cells of Rhizobium etli mL-1. Regardless of the application method, the yield obtained with the inoculation was equivalent to that of N from urea; however, the application in the furrows, at 0.6 L ha-1, is more advantageous due to the operational practicality and reduced costs.

title: Development of ic-Elisa for the screening of aflatoxin contamination in the peanut production chain

description: Abstract: The objective of this work was to standardize and validate an indirect competitive enzyme-linked immunosorbent assay (ic-Elisa), as a low-cost tool, to monitor the presence of aflatoxin in common and blanched peanuts (Arachis hypogaea) in the production chain. The presence of aflatoxin B1, moisture content, and water activity were analyzed in 60 samples of the peanut cultivar Runner IAC 886, from the 2014/2015 and 2015/2016 harvests of the region of Alta Paulista, in the state of São Paulo, Brazil. The validation showed an adequate linearity (R2 = 0.999), and limits of detection and quantification of 1.13 and 3.59 μg kg-1, respectively. Recovery rates of 104, 102, and 107% at the concentrations of 4, 10, and 20 μg kg-1 aflatoxin B1, respectively, were also recorded. The ic-Elisa showed a good reproducibility with a high-intraday precision, with 1.87% coefficient of variation (CV), and interday precision with 6.75% CV. The moisture content ranged from 4.0 to 7.2% (mean of 5.8%), and the water activity from 0.4848 to 0.6997 (mean of 0.5990) for the tested samples. Aflatoxin B1 was present in concentrations ranging from 1.13 to 29.2 μg kg-1, with only two samples (3.3%) exceeding the maximum allowed limit of 20 μg kg-1. The ic-ELISA developed here is an accessible tool for the rapid monitoring of aflatoxin contamination in the peanut production chain.
