title: Adrenergic receptor β3 is involved in the memory consolidation process in mice

description: Attention and emotion have a positive impact on memory formation, which is related to the activation of the noradrenergic system in the brain. The hippocampus and amygdala are fundamental structures in memory acquisition, which is modulated by noradrenaline through the noradrenergic receptors. Pharmacological studies suggest that memory acquisition depends on the action of both the β3 (β3-AR) and β2 (β2-AR) receptor subtypes. However, the use of animal models with specific knockout for the β3-AR receptor only (β3-ARKO) allows researchers to more accurately assess its role in memory formation processes. In the present study, we evaluated short- and long-term memory acquisition capacity in β3-ARKO mice and wild-type mice at approximately 60 days of age. The animals were submitted to the open field test, the elevated plus maze, object recognition, and social preference. The results showed that the absence of the β3-AR receptor caused no impairment in locomotion and did not cause anxious behavior, but it caused significant impairment of short- and long-term memory compared to wild-type animals. We also evaluated the expression of genes involved in memory consolidation. The mRNA levels for GLUT3, a glucose transporter expressed in the central nervous system, were significantly reduced in the amygdala, but not in the hippocampus of the β3-ARKO animals. Our results showed that β3-AR was involved in the process of acquisition of declarative memory, and its action may be due to the facilitation of glucose absorption in the amygdala.

title: Performance of 'Emerald' and 'Jewel' blueberry cultivars under no-chill incidence

description: ABSTRACT Climate is a limiting factor for cultivating blueberries in new areas in Brazil, being the commercial production restricted only to the colder and high-altitude regions of the southern states. This study aimed to evaluate the performance of low-chill requirement 'Emerald' and 'Jewel' blueberry cultivars. For that, the stages of vegetative growth, sprouting, flowering fruiting and yield were assessed. The 'Emerald' cultivar has two peaks for both flowering and fruiting, with the main harvest period occurring between August and October, while the 'Jewel' cultivar shows two peaks for budding, but only one flowering peak and only one harvest, which extends from October through January. For both cultivars, the production occurs during the off-season of the internal and external markets, resulting in higher fruit prices. Growing both cultivars is feasible in a subtropical region with no-chill incidence, thus demonstrating that these cultivars have much lower chill requirements than those referred to in the literature, and favoring, this way, the fresh fruit production during the off-season of the main producing countries in the northern hemisphere.

title: Surface treated bagasse fiber ash on rheological, mechanical properties of PLA/BFA biocomposites

description: Abstract The use of silica based bagasse fiber ash (BFA) as a reinforcing filler in polylactic acid (PLA) biocomposites was examined. The effects of surface-treated BFA on the rheological, swelling behavior, and mechanical properties and water absorption of biocomposites were studied. BFA was treated using a silane coupling agent (Bis-[3-(triethoxysilyl)-propy]-tetrasulfide). Composites with BFA were varied from 5 to 25wt.%. The PLA/BFA composite melts were pseudoplastic non -Newtonion fluid and exhibited a shear thinning behavior. The viscosity of the surface-treated BFA biocomposites was higher than that of the untreated. The viscosity of the composites decreased with increasing BFA content and shear rate. The extrudate swell of the composites increased with increasing shear rate, whereas it decreased with increasing BFA content and die temperature. The extrudate swell tended to be suppressed when surface-treated BFA was used. Silane treated BFA composites showed improvement in their mechanical properties, and exhibited significantly reduced water absorption.

title: Influence of the cleaning system of conveyor belts on microbiological quality of poultry meat

description: ABSTRACT This study focused on assessing the microbiology of conveyor belts surfaces, cleaned or not with pressurized water, and verification of the influence of this process on the microbiological quality of poultry meat. A reduction on mesophilic, psychrotrophic and Enterobacteriaceae counts (P&lt;0.05) on dry conveyor belts compared to wet ones was observed. For the chicken leg (consisting of drumstick and thigh) samples, no statistically significant differences were detected on counts of indicators of microorganisms on poultry legs (composed by drumstick and thigh). For poultry meat conducted on wet or dry conveyor belts, 99% and 86%, were positive for Listeria spp, respectively. Only one sample of chicken leg was positive for presence of L. monocytogenes. These results demonstrate that there is no need to use water for cleaning conveyor belts during processing, which allows a reduction on the use of potable water in poultry slaughterhouses without jeopardizing food safety and public health.

title: THE WORK IN THE FAMILY HEALTH STRATEGY AND THE PERSISTENCE OF CURATIVE PRACTICES

description: Abstract The research had the goal of analyzing the perception regarding the work on the Family Health Strategy. We conducted a case study in the city of João Pessoa, in the state of Paraíba, Brazil, in 2014, with a questionnaire applied to a sample of workers with higher education (n = 342), interviews with managers (n = 6), professionals (n = 12), and a simple in loco observation. The data were treated by means of an analysis of the content and by descriptive statistics. The most evident qualitative goal of the work performed by the Family Health Strategy was improving the health conditions of the users. It was put into effect though the prevention, promotion, education and treatment of diseases, incorporating the expanded concept of health and autonomy of the population. However, according to the quantitative data, little time was devoted to these activities when compared to the time devoted to the spontaneous demands, generating a significant number of individual consultations. Activities regarding education, prevention, promotion and group approaches must be stimulated and incorporated into the everyday activities of the Family Health Strategy in a manner that intersects all of the actions, in which the expanded medical practice is a powerful tool. More involvement on the part of the professionals in these activities will enhance the quality of the assistance though interprofessionality, and will help break free from curative practices.

title: WEEKLY WORKLOAD FOR NURSES IN BRAZIL: CHALLENGES TO PRACTICE THE PROFESSION

description: Abstract The study had the goal of presenting the distribution of nurses in the job market with a weekly workload greater than or equal to forty hours according to the regions of Brazil and the kind of workplace (whether in the private or public sectors). It was a cross-sectional study, conducted between 10 and 27 of February 2017, with on-line data from the medical-sanitary researches conducted in 2002, 2005 and 2009 by the Brazilian Institute of Geography and Statistics. We analyzed a total of 179,337 nurses in the 3 evaluated years. We compared their proportions according to each geographical region of Brazil and the workplace using Pearson’s Chi-squared test (α = 5%). Nursing was the only college-level healthcare occupation that presented a larger and increasing proportion of professionals with a weekly workload greater than or equal to 40 hours (p &lt; 0.001), and this proportion is greater in the public sector and in the Northern, Midwestern, and Southern regions of the country. The occupation of nurse still has an unfavorable workload, which constitutes a challenge to the nurses and to nursing as a profession.

title: Viability of ovine spermatozoa collected from epididymides stored at 18°-25°C for 48 hours post mortem

description: ABSTRACT The objectives of this study were to verify the time during which viable ovine spermatozoa could be recovered from the cauda epididymis kept at ambient temperature (18-25°C). Sperm collected in an artificial vagina (AV) were used as control. Spermatozoa samples were collected with an AV and from epididymis at 0 (G0), 6 (G6), 12 (G12), 24 (G24), and 48 (G48) hours post mortem. Total motility (TM), progressive motility (PM), hypo-osmotic membrane integrity test (HOST) and morphological changes were assessed. TM decreased (P&lt;0.05) from 24 hours post mortem (70.0±1.9%) compared to AV (86.4±1.0%). PM decreased (P&lt;0.05) from 12 hours after death (31.3±4.0%) compared to AV group (73.2±1.4%). The percentage of viable cells in HOST decreased (P&lt;0.05) in the G48 (60.0±8.9%). Spermatozoa recovery was lower (P&lt;0.05) 48 hours after death (2064.2±230.7 x 106 spermatozoa) compared to G0(2623.6±288.4 x 106 spermatozoa). In conclusion, under the conditions of this study, it would be possible to use epididymal spermatozoa recovered up to 24 hours after death for artificial insemination or in vitro fertilization; however, fertility trials are necessary to prove this hypothesis.

title: Profile of immunoglobulins, clinical and bacteriological cure after different treatment routes of clinical bovine mastitis

description: ABSTRACT The present study aimed to evaluate the profile of immunoglobins profile, clinical and bacteriological cure after different treatment routes of clinical bovine mastitis. Here, 30 Holstein cows with clinical mastitis in one quarter were uniformly divided into: 10 dairy cows that received 8.5mg of cefquinome sulphate administrated intramammarily during three consecutive milkings and 2.5mg/kg of enrofloxacin administrated parenterally during three consecutive days (Group 1); 10 dairy cows that received 8.5mg of cefquinome sulphate administrated intramammarily during three consecutive milkings (Group 2); and 10 dairy cows that received 2.5mg/kg of enrofloxacin administrated parenterally during three consecutive days (Group 3). Milk samples for somatic cell count, California Mastitis Test (CMT), bacteriological culture and quantification of IgG1, IgG2, IgM and IgA were collected before antimicrobial treatment, and after two, five and 12 days after the antimicrobial treatment. The combined treatment was more effective in the clinical cure rate, reduction of somatic cell count and CMT scores. Furthermore, the results demonstrated that milk concentration of different Igs classes were not related to prognosis of bovine clinical mastitis, and then cannot be considered as robust markers associated with clinical and bacteriological cures.

title: Welding strength of NiTi wires

description: ABSTRACT Objective: To identify the appropriate power level for electric welding of three commercial brands of nickel-titanium (NiTi) wires. Methods: Ninety pairs of 0.018-in and 0.017 × 0.025-in NiTi wires were divided into three groups according to their manufacturers - GI (Orthometric, Marília, Brazil), GII (3M OralCare, St. Paul, CA) and GIII (GAC,York, PA) - and welded by electrical resistance. Each group was divided into subgroups of 5 pairs of wires, in which welding was done with different power levels. In GI and GII, power levels of 2.5, 3, 3.5, 4, 4.5 and 5 were used, while in GIII 2.5, 3, 3.5 and 4 were used (each unit of power of the welding machine representing 500W). The pairs of welded wires underwent a tensile strength test on an universal testing machine until rupture and the maximum forces were recorded. Analysis of variance (ANOVA) and post-hoc tests were conducted to determine which subgroup within each brand group had the greatest resistance to rupture. Results: The 2.5 power exhibited the lowest resistance to rupture in all groups (43.75N for GI, 28.41N for GII and 47.57N for GIII) while the 4.0 power provided the highest resistance in GI and GII (97.90N and 99.61N, respectively), while in GIII (79.28N) the highest resistance was achieved with a 3.5 power welding. Conclusions: The most appropriate power for welding varied for each brand, being 4.0 for Orthometric and 3M, and 3.5 for GAC NiTi wires.
