To compare the airway permeability and the size of the maxillary sinuses in relation to the skeletal class. 90 lateral skull radiographs were divided into 3 groups, comparing the 3 skeletal classes, which were determined with Steiner's ANB measurement, and these were once in two subgroups that were men and women, in any McNamara analysis was used for the analysis of airways and for the maxillary sinus area measurements were made an antero-posterior and cephalic-caudal. When comparing males with females, statistical significance was identified in the upper class II route (p=£0,017), lower class III airway (p=£0.006). At least skeletal classes in men, differences were identified in the upper airway in classes I vs III (p=£0.05), lower in class I vs III (p=£0.001) and II vs III (p=£0.044). With respect to women, significance was identified in the upper airway when comparing class I vs II (p=£0.043), lower airway in class II vs. III (p=£0.05), maxillary sinus length to class I vs II (p=£0.017). Between skeletal class I and class II, maxillary sinus size was shorter in length in skeletal class II women. Between class I and skeletal class III in men, a lower length was found in the upper and lower airways in class I. The airways were found to be smaller in class II subjects [ABSTRACT FROM AUTHOR]

Background and aims: Ecological knowledge of wildlife shows that species are not equally important to human communities. The present work aims to identify the ethnospecies of higher cognitive salience to local people, and to explain their salience based on the cultural value they are assigned. M&M: The Sutrop's cognitive salience index of each ethnospecies and its statistical significance were calculated from fauna free lists. Descriptive statistical and qualitative analysis of uses and perceptions was carried out through the nature's contributions to people categories, using interviews and observation. Results: The free lists recorded a total of 100 ethnospecies, corresponding to birds (58%), mammals (18%), insects (13%), reptiles (7%), and amphibians and arachnids (2% each). Positive and negative contributions were detected in thirty-eight ethnospecies, although only eleven were statistically significant. Among the positive ones, material contributions stand out, followed by non-material and regulating ones. Among the negative, contributions were linked to damage to domestic animals and dangerousness. Additionally, relational and non-anthropocentric values appeared. Discussion and conclusions: Among relevant ethnospecies, those with the greatest number of positive contributions stand out. Also some related to negative perceptions for being responsible for attacks on domestic animals, and their dangerousness. The results provide inputs for policy makers and to re-think the links of local people with the fauna. [ABSTRACT FROM AUTHOR]

Orthognathic surgery is performed in subjects with some type of skeletal alteration. Maxillomandibular movements have an impact on the airway (AW) and this aspect must be included into surgical planning. The aim of this research is to determine the changes in the AW after orthognathic surgery. A pilot study was conducted including 51 subjects with class II and class III facial deformity; they were included using the ANB angle and the type of dental occlusion. Cone beam computed tomography were performed showing the maximum volume in the airway and the minimum and maximum areas; in addition, the position of the hyoid bone and the angle of the mandibular plane were included to relate it to the morphology of the AW; to define statistical significance, a value of p<0.05 was established, including the student's t-test and the t-test. The results showed that class II subjects significantly increased the volume and maximum and minimum areas of the AW; skeletal class III subjects did not presented significant differences between the pre- and post-surgical stage; the hyoid bone was in an anterior position in both class II and class III cases. It is possible to conclude that AW improves substantially in subjects with facial class II and remains unchanged in subjects with facial class III. [ABSTRACT FROM AUTHOR]

In the present study, molecular interaction fields are applied to a data set of forty 5-(nitroheteroaryl)-1,3,4-thiadiazol derivatives to generate a 3D-QSAR model. The statistical significance of the 3D-QSAR model is built as reported on the literature. External validation indicates that the 3D-QSAR model is robust and that it has predictive capacity. The results show that the model has steric (59.80%) and electrostatic (40.20%) properties that play an important role in leishmanicidal activity. Analyses of contour maps extracted from molecular interaction fields provide insights on the possible structural modifications of 5-(nitroheteroaryl)-1,3,4-thiadiazole derivatives. These modifications can serve to obtain new derivatives to improve their biological activity. In conclusion, the biological activities calculated for training and test sets show a high degree of concordance with experimental values, suggesting that the constructed 3D-QSAR model is useful for designing new 1,3,4-thiadiazoles derivatives with leishmanicidal potential.

This study evaluated soil organic carbon sequestration (SOC) in four vegetation covers (secondary vegetation [VS], forest plantations of Eucalyptus globulus (EUC) and Pinus patula [PIN] and pastures [PAS]), and its correlation with the physicochemical properties of the soil. Soil samples were taken at two depths in the A horizon (0-10 and 10-20 cm). Soil physicochemical variables were measured to evaluate their relationship with changes in SOC sequestration. We found that the highest SOC storage was in horizon A of EUC (100.5 ton C ha−1), followed by PAS (75.55 ton C ha−1), PIN (66.70 ton C ha−1) and SV (56.53 ton C ha−1). The SOC was significantly and positively correlated with the maximum water retention capacity, structural stability index, content of sand, clay, and carbon in humic and fulvic acids. However, SOC was negatively correlated with apparent density, state of aggregation, silt content, pH and CICE. These results suggest that cover change significantly affects SOC sequestration, soil organic matter characteristics, and soil physicochemical properties. [ABSTRACT FROM AUTHOR]

The elderly female population usually presents damage to the articular discs or menisci of the knee (ADK), generally derived from degenerative cartilage processes that occur in osteoarthritis. Knowing the standard morphological patterns of ADKs in a specific demographic population allows clarity of the indigenous characteristics of that population. One way to characterize these patterns is through the design of Finite Element Models (FEM) that would enable predicting clinical and radiological abnormalities. So far, there is little evidence on the morphometric characteristics of ADKs in the Colombian population. Thus, the objective of the present study was to describe the morphometry of ADK in magnetic resonance imaging (MRI) of healthy Colombian women. In this study, 25 MRIs of the knee of Colombian women with normal weight were taken, with no history of knee pathology, trauma, or surgery, and with ages between 18 and 60 years. The analysis of the width of the posterior horn of the medial ADK (12.73 ± 2.42) compared to the lateral (8.04 ± 1.52) showed a statistically significant difference (p <0.05). On the other hand, the medial ADK presented an increased anteroposterior diameter (38.52 ± 2.71) compared to that of the lateral ADK (29.18 ± 2.75) close to statistical significance (p = 0.051). Similarly, the height of the anterior horn was found to be increased in the medial ADK (4.42 ± 0.79) compared to the lateral (3.66 ± 0.76), with a trend towards statistical significance (p = 0.063). Anatomically, it is recognized that the medial and lateral ADK adapt to the shape and size of the femoral condyles, which is in agreement with the results of the studied population where measurements show that medial ADK has a longer (anterior to posterior diameter) and a shorter height than the lateral ADK.

Introduction: Preventing the intra-hospital infections is one of the major concerns in the last year. To that end, different strategies have been set such as hospital isolation. However, there is a grate default in order to comply with the isolation measures Objective: To determine the sociodemographic and healthcare factors related to how to comply with the contact warnings by the visitors coming into a high complexity hospital in Medellín. Methods: It is a cross-sectional descriptive study including in total 126 visitors who were isolated aÆer a contact. Factors associated with the isolation compliance were identiAed based on a survey. Information was analyzed with SPSS soÆware by doing a logistic regression and statistical signiAcance was assumed as P<0.05. Results: Total adherence to isolation was 40.5%, which is mainly associated with two factors: availability of protective garments and to agree with their use. Conclusions: Ǽe factors deemed as best associated with the isolation compliance required that the institutions provided enough protective garments to the visitors and that both the visitors and the hospital staff can receive a better awareness-rising communication on this topic.

Data and the significance represent sequential structures for scientific relevance. The purpose of the study was to identify epistemological barriers in the architecture to data and the significance of the predictive model of science. The study was carried from January to July 2020, selecting 100 randomized Scopus articles through a random probabilistic sampling, using the ScienceDirect platform as a scientific search tool. Sequential structures were compared using the t-Student test, the results being considered significant with a confidence level of 95% and where differences were found between them (t = -53.88; p = 7.09). It was observed that the analysis for the data was less relevant compared to the importance attributed to its significance. It was concluded that the identification of the epistemological barriers for the architecture to data and the significance in the predictive model of science represents a guide to consider for the measurement of the variables and their interpretation towards scientific knowledge.

The immigrant inflows received from 2015 propose several questions regarding their impact on the Chilean labor market. The literature on this subject is extensive, demonstrating the relevance and scope that such processes could mean in the economic and social levels. In this sense, this document has carried out an analysis using the parallel trends methodology in order to test the potential impacts of immigration inflows on average wages in Chile. Preliminary analyzes at regional level fail to detect changes in the treated group compared to the control group. However, when this analysis is focused at commune level, we can see changes potentially attributable to immigration inflows. The statistical significance of the treatment period (period related to the immigration inflows) is evaluated with other variables related to wages (that is, education, experience, and gender). The results support the statistical significance of the treatment period and the rest of the explanatory variables of wages. Despite these results, this analysis does not seek to conclude a relationship between the processes of immigratory flows and changes in wages, rather, it aims to provide a background that allows further analysis of this phenomenon with the support of deeper and specific.

Selenodeficiency has a negative impact on the immune response of animals. The objective of the work was to evaluate selenium supplementation and its effect on the response against Mannheimia haemolytica and its leukotoxin. 21 rabbits were used, these were distributed in three groups (n=7); A: Selenium plus bacterintoxoid was administered; B: the bacterin-toxoid was administered. C: considered control. Blood selenium content was estimated by atomic absorption spectrophotometry. The response to antigens was evaluated through an ELISA. An analysis of variance and Tukey were performed to determine statistical significance, considering a P value <0.05. In selenium quantification, a difference was observed between A with respect to B and C (P <0.05). In the evaluation of IgG against M. haemolytica, there was a difference between A with respect to B and C (P <0.05). For IgG against leukotoxin, no differences were observed between A and B (P> 0.05), but of these with respect to C (P <0.05). In conclusion, the supplemented animals had higher concentrations of selenium. This had positive effects on the response against M. haemolytica, however, no differences were found for the response against leukotoxin. [ABSTRACT FROM AUTHOR]

The Swedish authorities reported, for the year 2002, the presence of acrylamide in a wide variety of foods and its carcinogenic effects on humans. This organic compound is present in foods that contain depleted sugars, asparagine and which in turn are subjected to thermal processes that exceed 120°C. The objective of this study was to evaluate the effect of some extraction parameters on the percentage of acrylamide recovery in potato chips samples. For this purpose, commercial samples, standard solutions for the calibration curve and doping, n-hexane, type I water and Carrez solution were used. Additionally, vortex, ultrasound, centrifuge and HPLC were used. The analitycal method was assessed according to linearity, limit of detection and quantification. The statistical significance of the variables was tested by applying the t-Student test. Recoveries of the studied analyte of up to 86% were achieved, in addition, the following extraction parameters were established: 8 g MgSO4 and 1 g NaCl of Carrez solution, 0,5 g of sample, doping at the time of extraction. The parameters evaluated have an important in- fluence on the performance of the extractions, except ultrasound, which was not the only significant effect on the percentage of acrylamide extraction.

The aim of the present study was to determine the physical properties of the Guazuma crinita wood by conventional methods, as well as to estimate these properties by near infrared spectroscopy (NIR) through the development of multivariate calibration models. The samples were obtained from five trees and from three levels longitudinally for 5 and 8 years of age randomly selected from a plantation in Puerto Inca, Department of Huánuco (Perú). Basic density, volumetric, tangential and radial contraction were determined by the conventional methods. Models were developed by regression of partial least squares (PLS) through mathematical transformations. For the validation of the models, a new group of samples -which did not participate in the development of the model were used. Statistical significance was found F5años = 191,5; F8años =84,9) between the different heights in the stem. Basic density and volumetric contraction show values of Rc² (0,88 and 0,83) and RPDp (1,55 and 3,27) acceptable for prediction. [ABSTRACT FROM AUTHOR]

Aim. To identify the state of the art of spirituality and the possible relationships with alcohol consumption in Alcoholics Anonymous (AA). Method. Cochrane Handbook for Systematic Review was used. DeCS and Mesh descriptors were included as search strategy in all possible combinations, as well as truncation and boolean operators: Spirituality, Alcohol Consumption and Alcoholics Anonymous. Results. Spirituality and positive changes in it positively predict days of abstinence percentage and make a negative prediction of the amount of drinks per day; statistical significance was found among some spiritual practices as forgiveness and alcohol consumption decrease. Conclusions. AA program increases spirituality and predicts alcohol consumption in AA members. [ABSTRACT FROM AUTHOR]

Objective. To evaluate the coadyouvant efficacy of a combination of cosmetics ingredients in the form of a lipolytic cream with hypocaloric diet and physical activity and compared with hypocaloric diet and physical activity for overweight and obesity treatment in patients. Material and methods. It was conducted a monocentric, open-label, randomized study of parallel groups of 102 patients that consulted in a medical-clinical nutrition center for overweight and obesity treatment. Height, arm, waist, hip and thigh perimeters and the analysis of segmental body composition with an impedance team were studied in patients between 18 and 99 years, of both sexes with voluntary attendance and with presence of overweight or obesity during a period of 16 consecutive weeks. The data were statistically analyzed by comparing the initial and final values of all the values in both groups. Safety was monitored by the incidence of adverse events. A value of p<0.001 was considered as statistical significance. Results. Of the total of 102 patients, the inclusion and exclusion criteria were applied; 45 and 47 cases are included and analyzed respectively. The age ranges between 39.16 vs 42.09 years (p = 0.246); initial weight 85.9 kg vs 85.08 kg (p = 0.810); perimeters: initial waist of 100.4cm vs 99.7cm (p = 0.826); initial arm of 32.9cm vs 33.4cm (p = 0.453); initial hip: 108.6cm vs 107.7 (p = 0.666).
