I found allocentrism-idiocentrism to be unrelated to any of the non-PRF scales in a direct way. Multiple regression analyses showed the covariates of idiocentrism to differ among men and women. Idiocentric men reported low affiliative needs, high autonomy needs, and were low in private self-consciousness. Idiocentric women were low in succorrance needs.In further studies, I examined the relation of allocentrism-idiocentrism to person perception, and to both interpersonal behavior and attraction. I found scarce evidence, in partner descriptions, of identity-consistent behavior during brief interactions for both allocentrics and idiocentrics. Furthermore, allocentrics and idiocentrics did not appear to differ in their person-perception abilities, but men tended to consider others to be similar to themselves. The attractiveness of experimental partners was unrelated to their allocentrism or idiocentrism, or to their levels of private and public self-consciousness. Instead, their attractiveness was influenced by the ways they were perceived by their partners. Some evidence indicated that persons who are perceived as similar to oneself are better liked. However, people who were perceived as cooperative, flexible, attentive, independent, and self-reliant were better liked than either selfish or dependent individuals.Descriptions and evaluations of experimental partners suggested that allocentrism and idiocentrism may be opposite poles in a multidimensional space.

Following annual mechanized harvest, nitrogen (N) fertilizer is commonly applied during the ratoon cane sprouting phase through furrows along the side of plant rows (subsurface application) or banded on the surface. With subsurface application, mechanical operations are hampered by the trash coverage that remains after harvest; furthermore, opening furrows can partially damage roots. However, with soil surface application, nutrient uptake efficiency is decreased as a result of microbial immobilization and losses through ammonia volatilization and runoff. Thus, to achieve subsurface application for ratoon cane with minimal mobilization of the system (soil, straw and roots), this work aimed to (i) develop and evaluate a mechanical prototype that enables a soil punching process in ratoon cane and (ii) evaluate the cane yield using the soil punching method for liquid N fertilizer injection compared to liquid N fertilizer applied alongside of plant rows on the surface and subsurface (through furrows). To evaluate the punching mechanism, we performed a kinematic simulation (puncher tip displacement and injection time interval), tests in a soil bin and ratoon cane field. Based on prototype operations, the average distance between applications was 300 mm, with an average depth up to 90 mm, which was similar to the design requirements. Regarding results of liquid N fertilization methods in a ratoon cane field, we found that the incorporation treatments (soil punching and subsurface application through furrows) achieved slightly better cane yield (98-96 Mg ha À1) when compared to the surface application (91 Mg ha À1) and control treatment (75 Mg ha À1). In general, the soil punching was considered as a promising alternative method for supplying liquid fertilizer at the subsurface using low-energy power (approximately 745 W) with minimal environmental impact. 2016 Elsevier B.V.

CEA has been considered the first-line treatment for carotid stenosis worldwide, and the safety and efficacy of CAS compared to CEA remains in question. Objective: The purpose of this study is to compare the practice and outcomes of CAS and CEA in a real-world setting within public university hospitals in Brazil. Methods: This study will be a prospective 5-year analysis of treatment for atherosclerotic carotid stenosis with CEA and CAS performed at 5 centers affiliated with the Vascular Study Group at public university hospitals in Brazil. The indications for the procedures will be determined by each surgeon's individual discretion, in accordance with preoperative risk evaluation. The primary outcome measures will be (1) any in-hospital stroke or death, and (2) any per-procedural stroke, death, or myocardial infarction (MI). Patients undergoing CEA in conjunction with cardiac surgery will be excluded from the study. Multivariate logistic regression will be performed to identify predictors of stroke or death in patients undergoing CEA and CAS. All tests of significance will be performed at the .05 level. This study was approved by the Committee of Ethics in Research at the University Hospital of Ribeirao Preto Medical School, and in all other participating institutions linked to National Research System and National Board of Health in Brazil (Process 15695/2011). Results: This study is currently in the recruitment phase, and the final patient is expected to be enrolled by the end of 2018. We hope to recruit approximately 800 patients to the study. Analyses will focus on primary end points for patients that are allocated to each treatment group. During the per-procedural period, the occurrence of the primary end point components (stroke, MI, or death) for CAS and CEA will be analyzed for symptomatic or asymptomatic subjects. Conclusions: The analyses of the primary endpoints (and all others variables of the study) are expected to be published in 2019 in a peer reviewed journal, and results will be presented at scientific meetings, with summary results published online. This study will obtain new data related to the quality of treatment for carotid disease in Brazil at the primary training centers of future vascular surgeons, but the initial data that will be obtained and published (with the outcomes and complications) are restricted to the first 30 days postprocedure. This time restriction limits the comparison of the results that relate to the main goal of treatment, which is to decrease the risk of stroke over 5 years. The purpose of the study group is to continue the monitoring of patient records, and

Compare the morphological characteristics of normal and cancer cells derived from mammary glands of human and canine species. Materials and methods. 10 samples were collected of normal breast parenchyma and 14 from tumor parenchyma of the canine species, as well as six samples of normal breast parenchyma and three-tumor parenchyma of the human species. For the cell culture, a mammal cell culture technique was used, and, an avidin-biotin-peroxidase technique was used for the histochemical culture, with the use of monoclonal antibody 32-2B (anti-desmoglein-1). Results. With histological and morphological studies, the cells of the normal human mammary gland showed similarities with cells of normal canine mammary gland. Adhesion and proliferation of normal cells was observed in both species bin approximately three months of culture. Normal cells of human and canine species showed low proliferative activity when compared with cancerous cells of the species under study. Groups of epithelioid cells that adhered to the substrate of the two cultures had dependence on stromal cells, because as the fibroblastoid cells were removed, epithelioid cells stopped their growth. Conclusions. Comparing the results obtained by immuno-histochemical analysis of normal cells of women and bitches, it was possible to observe changes in the pattern of staining in cancer cells in both species, demonstrating that the structures related to cell adhesion (desmosomes) may be altered.

In recent years, an increased understanding of the importance of intestinal microbiota for human physiology has been gained. In the steady state, commensal microorganisms have a symbiotic relationship with the host and possess critical and distinct functions, including directly influencing immunity. This means that recognition of commensal antigens is necessary for the development of complete immune responses. Therefore, the immune system must face the challenge of maintaining mucosal homeostasis while dealing with undue passage of commensal or pathogenic microbes, as well as the host nutritional status or drug use. Disruption of this fine balance has been associated with the development of several intestinal inflammatory diseases. In this review, we discuss the mechanisms involved in the modulation of host-microbe interactions and how the breakdown of this homeostatic association can lead to intestinal i...

This paper presents an evaluation of the lower lip potential to control an input device, according to Fitts' law (ISO/TS 9241-411:2012 standard). The results show that the lower lip throughput is comparable with the thumb throughput using the same input device under the same conditions. These results establish the baseline for future research studies about the lower lip capacity to operate a computer input device.

This paper presents an evaluation of the lower lip potential to control an input device, according to Fitts' law (ISO/TS 9241-411:2012 standard). The results show that the lower lip throughput is comparable with the thumb throughput using the same input device under the same conditions. These results establish the baseline for future research studies about the lower lip capacity to operate a computer input device.
