title: Acetone recovery in laboratories wastes: an approach of aspects of management, operation and environmental efficiency

description: The objective of this work was to exclusively improve the management of wastes constituted mainly by organic solvents, due to the opportunities for improvements in the processing of such substances in the institution where the studies were realized. By means of the tests carried out in the distillation system using acetone as a reference, advantages and disadvantages were found with increasing/decreasing the temperature used in the process. From the use of gas chromatography, it was possible to obtain a more precise control of the quality of the recovered product and also to verify the high efficiency of the distillation process in the separation of the solvent from the other contaminants present in the waste. And in terms of comparison of treatments, distillation proved to be environmentally more sustainable and about 8 times more economical than incineration.

title: Toxicological properties of an aqueous extract of Aristolochia triangularis leaves, using the brine shrimp lethality and Allium cepa bioassays

description: ABSTRACT: The aqueous extract of Aristolochia triangularis leaves showed activity against Artemia salina larvae, with an LD50 of 370.6 µg/mL. In experiments with Allium cepa seeds, the extract caused a 51.26% reduction in the germination index, inhibited mean root growth, and was cytotoxic at concentrations of 668 and 2,000 µg/mL. Its antioxidant activity was additionally assessed in this research and the ferric reducing antioxidant power value was found to be 391.2 µM/g. Such health-beneficial property can be attributed partly to the total phenolic content, spectrophotometrically determined as 52.67 mg/g. The occurrence of cytotoxicity suggested caution when consuming teas from A. triangularis leaves for medicinal purposes, and equally reveals the need for further studies to investigate their adverse effects.

title: Development of Oryzophagus oryzae (Costa Lima) in rice cultivars

description: ABSTRACT Insect-resistant cultivars are essential for improving the management of pests such as Oryzophagus oryzae (Coleoptera: Curculionidae), which significantly decreases flooded rice yields. However, the degree of benefit brought to the crop varies with the type of resistance. This study aimed to evaluate the resistance of rice cultivars to O. oryzae, inferring about antixenosis and antibiosis effects on the development of larvae and adults. Under natural infestation conditions, a biennial experiment was carried out using a latin square design, with six treatments (cultivars) and plots with 30 plants (five rows of six plants equidistant 20 cm) irrigated with water depth of 15 cm. The number and weight of larvae by size, as well as the number, weight, emergence rate, and sex ratio of adults, were evaluated using standard soil, plant and root samples. Except for adult sexual ratio, the cultivars differed (p ≤ 0.05) for the other variables, whose relationship evidenced antibiosis effects at the larval stage, making possible to conclude that: the BRS Firmeza cultivar has resistance to O. oryzae due to antixenosis and/or antibiosis effects; BRS Ligeirinho is susceptible to this insect species, resulting in a relatively higher number of well-developed larvae and adults; and IRGA 417 shows an antibiosis action, restricting the adult emergence rates. The weight of adults gives a greater accuracy to the evaluation of the harmful effects of rice cultivars on the O. oryzae development.

title: The health and nutrition of indigenous children in Chile (Mapuche)

description: The aim of this study was to conduct a review of the health and nutritional status of Chilean indigenous children, specifically Mapuche children, as published in the literature and specific population-based studies. The searches were conducted in PubMed and LILACS in the last 15 years. From 2006 to 2015, the poverty rate was higher in the indigenous population, with a decrease in the gap from 16% in 2006 to 7.7% in 2015 (p &lt; 0.001). In the first decade of this century, infant mortality in indigenous children was 17.1/1,000 live births, while in non-indigenous children it was 8.8/1,000, and the gap was maintained in the five-year follow-up (p &lt; 0.001). Newborns with birthweight &lt; 2,500g in the year 2000 did not reach 6% (5.6% in non-indigenous and 5.2% in indigenous children). Low height at first school enrollment was 8.4% in indigenous schoolchildren and 3.1% in non-indigenous children, decreasing to 3.7% in indigenous children and 2.6% in non-indigenous children in 2004, while obesity increased more in indigenous children, reaching 24.2% in indigenous and 25.3% in non-indigenous children (p &lt; 0.001). Menarche appeared four months later on average in indigenous girls (12.7 years), and body mass index, waist circumference, and fat mass were significantly greater in indigenous girls at the time of thelarche, as was the overweight rate (55%, vs. 42% in non-indigenous). Mapuche children show favorable health and nutritional status compared to indigenous children elsewhere in Latin America, but there is still an adverse gap compared to non-indigenous Chilean children. This inequality affecting indigenous Chilean children should be acknowledged and corrected.

title: Antimony resistance in Leishmania (Viannia) braziliensis clinical isolates from atypical lesions associates with increased ARM56/ARM58 transcripts and reduced drug uptake

description: BACKGROUND In addition to the limited therapeutic arsenal and the side effects of antileishmanial agents, drug resistance hinders disease control. In Brazil, Leishmania braziliensis causes atypical (AT) tegumentary leishmaniasis lesions, frequently refractory to treatment. OBJECTIVES The main goal of this study was to characterise antimony (Sb)-resistant (SbR) L. braziliensis strains obtained from patients living in Xakriabá indigenous community, Minas Gerais, Brazil. METHODS The aquaglyceroporin 1-encoding gene (AQP1) from L. braziliensis clinical isolates was sequenced, and its function was evaluated by hypo-osmotic shock. mRNA levels of genes associated with Sb resistance were measured by quantitative reverse transcription polymerase chain reaction (qRT-PCR). Atomic absorption was used to measure Sb uptake. FINDINGS Although clinical isolates presented delayed recovery time in hypo-osmotic shock, AQP1 function was maintained. Isolate 340 accumulated less Sb than all other isolates, supporting the 65-fold downregulation of AQP1 mRNA levels. Both 330 and 340 isolates upregulated antimony resistance marker (ARM) 56/ARM58 and multidrug resistant protein A (MRPA); however, only ARM58 upregulation was an exclusive feature of SbR field isolates. CA7AE seemed to increase drug uptake in L. braziliensis and represented a tool to study the role of glycoconjugates in Sb transport. MAIN CONCLUSIONS There is a clear correlation between ARM56/58 upregulation and Sb resistance in AT-harbouring patients, suggesting the use of these markers as potential indicators to help the treatment choice and outcome, preventing therapeutic failure.

title: Effect of drying temperature on color and desorption characteristics of oyster mushroom

description: Abstract Oyster mushroom (Pleurotus ostreatus) slices were dried in a hot air dryer at three temperatures (45, 55 and 65 °C). The sorption isotherm of dried samples in the water activity (aw) range of 0.556-0.970 was also determined at three temperature levels. Moisture desorption isotherms were obtained from changes in water activities of oyster mushroom slices during drying, and the fitness of GAB, BET, Oswin, Henderson and Halsey isotherm equations to sorption data was calculated. The effect of temperature on color change kinetics of oyster mushroom slices was also investigated during drying. GAB model was the best equation for the prediction of the desorption moisture content of samples. Mathematical modeling of color change kinetics indicated that both zero and first order kinetic models were adequate to describe the browning index (BI) value; however, total color change (ΔE) followed zero-order kinetics. The values of the reaction rate constant, found after the drying at 45, 55 and 65 °C, of the ΔE value were respectively 0.058, 0.065 and 0.089.

title: Identiﬁcation and Characterisation of Alternative Splice Variants of Hoxb9 and Their Correlation with Melanogenesis in the Black-Boned Chicken

description: ABSTRACT Homeobox B9 (HOXB9) gene has been demonstrated to be associated with melanogenesis in chicken plumage by high-throughput RNA sequencing. In this study, we cloned and characterised HOXB9 in black-boned chickens. Two alternative splice variants (HOXB9-1 and HOXB9-2) were identiﬁed in chicken feather bulbs. Expression analysis of HOXB9 in 11 different chicken tissues by RT-PCR indicated that the two transcripts were only expressed in the kidney, abdominal fat, feather bulbs, skin, and small intestine. No HOXB9-1 or HOXB9-2 transcripts were detected in the breast muscle or the ovary. The two HOXB9 variants were expressed at significantly different levels in black feather bulbs and white feather bulbs (p&lt;0.01), and in black skin compared with white skin (p&lt;0.01). The results indicate that HOXB9-1 and HOXB9-2 may be involved in melanin formation in the plumage and skin. The expression of HOXB9-2 was higher in white than in black muscles (p&lt;0.05), HOXB9-2 may play a role in muscle melanogenesis. Our results suggest that HOXB9, which is partially regulated by alternative splicing, may be involved in the process of melanogenesis in the black-boned chicken.

title: Is the Eggshell Quality Influenced by the Egg Weight or the Breeder Age?

description: ABSTRACT For a long time, it has been said that eggshell quality decreases as eggs increase in size, but this increase is seen as the breeder age advances. Therefore, the present study aimed to evaluate the age and egg weight effect on Cobb 500 broiler breeders on eggshell quality. The quality measures tested were eggshell and mineral matter percentage, eggshell surface, shape and eggshell index, eggshell and membrane thickness and specific gravity. Eggs from 27, 31, 36, 40, 46, 48, 53, 58 and 63 week-old breeders were classified as eggs with a constant weight ranging from 63.8 ± 0.2; and eggs with increasing weight, according to age, being: 55.8g; 60g; 62.2g; 64.2g; 65.2g, 66.6g, 68.1g, 69.9g and 72.5g, respectively. The eggs weight did not influence the eggshell percentage and the specific gravity in seven of the nine tested ages, while for mineral matter in six of the nine studied ages. The shape and shell index, shell and membrane thickness are characteristics independent of egg weight. As the Cobb 500 broiler breeder age advanced, the mineral matter concentration and specific gravity maintained constant, the membrane thickness (R2&gt;70) reduced, and other studied variables were influenced in the same way for both treatments. Thus, the eggshell quality decrease with the advancing age cannot be attributed solely to the increase of egg weight with consequent increase in the eggshell volume and the surface, but there are also age-related factors.

title: Performance and development of gastric compartments of calves fed with cheese whey and transition milk

description: ABSTRACT: This study aimed to evaluate whether cheese whey associated with transitional milk or not, could serve as a suitable alternative to whole milk for calf rearing. For this, twenty-four male calves of crossbred Holstein-Zebu, were distributed in a completely randomized design with three treatments (8 calves per treatment) and fed for 60 days with one of the following liquid diets: i) 100% whole milk, ii) 50% whole milk and 50% cheese whey, and iii) 30% transitional milk and 70% cheese whey. There was no difference in food intake between treatments. The analysis showed that whole milk replacement did not alter the stomach weight or the ruminal cell proliferation when compared to treatment using 100% whole milk; however, the transitional milk/cheese whey group showed larger ruminal papillae. These results suggested that a transitional milk-cheese whey diet associated with solid food and proper nutrient complements might enhance the post-natal development of rumen papillae in calves, which might contribute to prepare them for weaning.

title: Humor intervention in the nurse-patient interaction

description: ABSTRACT Objective: To describe the factors influencing the use of humor in nursing care, its applicability and benefits. Method: A scoping review was performed using the Arksey and O’Mally methodology. A search for articles published between 2008 and 2018 was performed using the platforms EBSCO Host, Virtual Health Library and Google Scholar. Results: From the initial 465 articles found, 17 were included for final revision. Data allowed to retrieve information on humor definition; its applicability as a nursing intervention; humor as a tool to improve nurse-patient communication and relationship; influence factors; type of humor interventions; humor benefits in health care context and; limitations and precautions of humor intervention. Conclusion: The use of humor promotes both communication and human interaction; it promotes well-being; helps deal/cope with difficult and unpleasant situations, reduces tension, discomfort and stress; and strengthens the immune system. This intervention should be used with caution.
