title: Keeping our immigrants healthy: hygienist doctrine in the Hospedaria de Imigrantes da Ilha das Flores

description: Abstract The Hospedaria de Imigrantes (Immigrant Lodgings) da Ilha das Flores was established in 1883 in accordance with the hygienist thinking of the time. Immigrants were isolated on the east coast of Guanabara Bay because of the epidemics of yellow fever which returned to the Imperial capital every summer since 1849-1850. Hygienists attributed the disease to the precarious health conditions in the city of Rio de Janeiro, which enabled germs to multiply and infect the atmosphere. As physicians reinterpreted the disease in light of Pasteurian theory, new procedures were adopted to receive immigrants, changing the structure and function of the facility on Ilha das Flores.

title: EFFECTS OF SAGITTAL BALANCE DIFFERENCES ON SPONDYLOLISTHESIS

description: ABSTRACT Objectives: This study aimed to compare the lumbar lordosis (LL) and spinopelvic parameters of patients with stage 1–2 spondylolisthesis to those of the normal population and demonstrate the importance of these parameters in sagittal balance. Methods: The lumbosacral parameters on the lateral radiographs of a total of 125 patients were retrospectively compared. Lumbosacral parameters including pelvic incidence (PI), pelvic tilt (PT), sacral slope (SS), lumbar lordosis angle (LLA), L5 incidence (L5I), L5 slope (L5S), and sacral table angle (STA) were compared between groups. Results: Comparison of the parameters between groups revealed no sex-based differences (p &gt; 0.05). Conclusions: Abnormal sagittal spinopelvic parameters are commonly examined for their effects on the development of spondylolisthesis and should be used in routine practice. We found that the low SS values in our study, unlike those of other similar studies, may be a compensatory mechanism developed to reduce pain and maintain sagittal balance. Level of Evidence II; retrospective study.

title: A COMPARATIVE STUDY OF NUMERICAL APPROXIMATIONS FOR SOLVING THE SMOLUCHOWSKI COAGULATION EQUATION

description: ABSTRACT In this work, numerical approximations for solving the one dimensional Smoluchowski coagulation equation on non-uniform meshes has been analyzed. Among the various available numerical methods, finite volume and sectional methods have explicit advantage such as mass conservation and an accurate prediction of different order moments. Here, a recently developed efficient finite volume scheme (Singh et al., 2015) and the cell average technique (Kumar et al., 2006) are compared. The numerical comparison is established for both analytically tractable as well as physically relevant kernels. It is concluded that the finite volume scheme predicts both number density as well as different order moments with higher accuracy than the cell average technique. Moreover, the finite volume scheme is computationally less expensive than the cell average technique.

title: Difference of brain-derived neurotrophic factor expression and pyramid cell count during mastication of food with varying hardness

description: Abstract Previous studies suggested that mastication activity can affect learning and memory function. However, most were focused on mastication impaired models by providing long-term soft diet. The effects of chewing food with various hardness, especially during the growth period, remain unknown. Objective: To analyze the difference of hippocampus function and morphology, as characterized by pyramidal cell count and BDNF expression in different mastication activities. Materials and Methods: 28-day old, post-weaned, male-Wistar rats were randomly divided into three groups (n=7); the first (K0) was fed a standard diet using pellets as the control, the second (K1) was fed soft food and the third (K2) was fed hard food. After eight weeks, the rats were decapitated, their brains were removed and placed on histological plates made to count the pyramid cells and quantify BDNF expression in the hippocampus. Data collected were compared using one-way ANOVA. Results: Results confirmed the pyramid cell count (K0=169.14±27.25; K1=130.14±29.32; K2=128.14±39.02) and BDNF expression (K0=85.27±19.78; K1=49.57±20.90; K2=36.86±28.97) of the K0 group to be significantly higher than that of K1 and K2 groups (p&lt;0.05); no significant difference in the pyramidal cell count and BNDF expression was found between K1 and K2 groups (p&gt;0.05). Conclusion: A standard diet leads to the optimum effect on hippocampus morphology. Food consistency must be appropriately suited to each development stage, in this case, hippocampus development in post-weaned period.

title: NORMATIVE ISOMETRIC HIP MUSCLE FORCE VALUES ASSESSED BY A MANUAL DYNAMOMETER

description: ABSTRACT Objective: Hand-held dynamometry is a quantitative and accessible means of determining the isometric force of muscle groups. Methods: A total of 52 women aged 20–29 years with no complaints of hip pain who were sedentary or sporadically active and had a body mass index of 18.5–24.99 kg/m2 were included. All participants underwent bilateral assessments using hand-held dynamometry of the flexor, extensor, adductor, and abductor muscles as well as the internal and external rotator hip muscles. All hip movements were measured. All contraction data collected by the dynamometer are expressed in kilograms, normalized according to body weight, and expressed as percentages. Results: The flexor muscles exhibited an isometric muscle force of 38.54% of body weight versus a muscle force of 27.04% for the extensor muscles, 16.89% for the adductors, 16.85% for the abductors, and 17.09% for the external rotators, and 23.82% for the internal rotators. Conclusion: Standardization of isometric strength values according to body weight proved feasible. This result is important for clinical practice since it allows the establishment of patterns of normality and criteria for discharge, return to sports, or assessment of the impact of injuries in terms of loss of muscle strength. Level of evidence: III, Development of diagnostic criteria on consecutive patients (with universally applied reference “gold” standard).

title: Catalytic Dehydration of 1-Propanol Over Silica Containing Sulfonic Acid Groups

description: Mesoporous silica with strongly acid sulfonic sites were synthesized and used as catalytic supports for catalytic dehydration of 1-propanol. This porous material with a large surface area and high porosity were prepared by a simplified sol-gel in an acidic medium and impregnated easily by -SO3H groups. The experimental results indicate that the very strong acidic sites contained on the surface are the seats of the reaction involving two molecules of n-propanol. By hydrogen bonding, ether compounds as well as the corresponding alkene are obtained in appreciable yield.

title: Concentrations of major and trace elements in the soils, edible parts of crops and urine of farmers in agroecological communities

description: ABSTRACT. The relationship between soil and health is important for populations that depend on the local environment to meet their nutritional needs. This study aimed to evaluate the concentrations of major and trace elements in the soils, edible parts of crops and urine of farmers in agroecological communities. We collected samples of soil, edible parts of crops and urine of farmers and family members in 23 crop fields in agroecological communities from northeast Brazil. These samples were analyzed to concentrations of Al, As, Ca, Cr, Cu, Fe, Hg, Mg, Zn, and Pb in urine and discriminant analysis and principal component analysis were used to assess the data. Concentrations of potentially toxic elements in soils and crops of agroecosystems were below regulatory levels. Farmers living in agroecological communities present most of the essential and toxic elements in urine within the reference ranges. In general, results showed that urinary concentration of toxic elements among farmers and their families were below allowable limits, which may be due to the agroecological practices.

title: A new technique for tongue brushing and halitosis reduction: the X technique

description: Abstract The tongue is one of the primary sources of halitosis. The manual or mechanical removal of biofilm is known to decrease oral malodor. Objective: To evaluate a new tongue hygiene technique hereby referred to as “the X technique” and its effects on both halitosis and the number of microorganisms based on microbiological parameters and diagnostic features of the breath. Material and Methods: The study included thirty patients divided into a control group (patients without systematized guidelines of lingual hygiene, but who performed the mechanical cleaning of tongue dorsum, each in its own way), the 3R group (instructed to perform the movements of the X technique for 3 repetitions at each brushing), and the 6R group (instructed to perform 6 repetitions of the technique at each brushing). After two weeks, a new data collection was performed. Results: Patients in the 6R group presented the lowest score on the organoleptic assessment scale at the second consultation, followed by the 3R group and the controls. Regarding the self-perception of breath by the method of Visual Analog Scale (VAS), the control group did not perceive improvements in oral malodor; the results of the 3R group and the 6R group were similar. Conclusion: These results indicate that the X technique improves both measurements and perceptions of halitosis. Microbiological analyses revealed greatest reduction in the 6R group. The findings show that the X technique reduces both organoleptic scores and the number of bacterial colonies, and improves users’ perceptions of their breath.

title: Physical and microbiological characteristics process of composting waste from animals

description: ABSTRACT The objective of this study to characterize the process of continuous flow of composting and passive aeration of waste production and slaughter the goat and sheep industry and its generated organic compound. The composting process, performed in a brick barn, used solid residues (manure and carcass parts) from the slaughter of goats and sheep along with chopped dry elephant grass and tree trimmings. The treatments employed three moisture levels in the piles and four collections of samples from the piles at timed intervals (0, 30, 60 and 120 days), with three repetitions. The variables evaluated were the chemical and physical attributes of the compost generated. The treatments were three moisture levels applied in compost piles (30, 50 and 70% based on the housing of animals) and assembly times of the year (dry, transitional and humid) based on rainfall, with three replications. The variables were chemical, physical, microbiological and parasitological of the compound and its comparison with current legislation. The generated organic compound meets the specifications of the laws used for comparison. Regardless of the time of year or moisture applied, the composting process was effective in reducing environmental liabilities as carcasses. Composting promoted elimination of this pathogen, indicating that the compound can be used safely.

title: Participation of the autonomic cardiac system in dogs with chronic myxomatous degeneration of the mitral valve

description: ABSTRACT An exploratory multivariate analysis of factors of echocardiographic variables and those of the Holter test of 38 dogs with MVMD staged in three classes (class 1a, class 1b, class 2) of congestive heart failure proposed by the ISACHC. The purpose of this analysis was learning the processes that would explain the behavior of the variables described, using exploratory multivariate techniques of factors. Five independent factors were determined (PNS to SF) which altogether explain 82.17% of the shared variance of the data. It was identified that among the five factors, the first process (PNS) is the first factor in importance, recruiting the highest percentage of variance (37.96%) and represents the participation of the cardiac autonomic nervous system.
