North American entomophagy
Eating insects is not a common Northern American practice today. However, in the past a variety of insect species was consumed in Northern America (north of Mexico including Greenland). The aim of this literature review is to provide an historical overview of North American entomophagy based upon both peer and non-peer reviewed sources on this topic. Regional differences in insect consumption and reasons for being underreported are discussed. We show that North American natives, and in certain cases colonists, collected and consumed a large variety of edible insects. These are categorized per order and where available, information on how these species were collected and processed is provided. Lastly, we mention reasons for the renewed interest in edible insects in North America, and make suggestions for future studies
Assessment of the Italian version of the Internet Disorder Scale (IDS-15)
Much research has focused on the validation of psychometric tools assessing Internet addiction. One of the newest measures is the Internet Disorder Scale (IDS-15) based on the modified IGD criteria outlined in the Diagnostic and Statistical Manual of Mental Disorders (DSM-5). This study aimed at investigating the psychometric properties of the Italian version of the IDS-15 by examining the construct and the concurrent and the criterion-related validity and by identifying the taxonomy and the patterns of Internet users. A sample of 471 participants (Mage = 24.72 years, SD = 8.66; 256 males) was recruited from secondary schools, universities, and gaming halls. Confirmatory factor analyses supported the four-dimensional second-order structure and the three levels of the measurement invariance across gender. The reliability and the validity of the scale were confirmed, and the LPAs provided four classes of Internet users on the basis of the scores obtained in all four dimensions of the scale. The psychometric robustness of the Italian version of the IDS-15 was clearly demonstrated. Cross-cultural research should expand and generalize the present findings
Effects of Calcium Pyruvate Supplementation During Training On Body Composition, Exercise Capacity, and Metabolic Responses To Exercise
Objective: We evaluated the effects of calcium pyruvate supplementation during training on body composition and metabolic responses to exercise.
Method: Twenty-three untrained females were matched and assigned to ingest in a double blind and randomized manner either 5 g of calcium pyruvate (PYR) or a placebo (PL) twice daily for 30 d while participating in a supervised exercise program. Prior to and following supplementation, subjects had body composition determined via hydrodensiometry; performed a maximal cardiopulmonary exercise test; and performed a 45-min walk test at 70% of pre-training VO2 max in which fasting pre- and post exercise blood samples determined.
Results: No significant differences were observed between groups in energy intake or training volume. Univariate repeated measures ANOVA revealed that subjects in the PYR group gained less weight (PL 1.2 ± 0.3, PYR 0.3 ± 0.3 kg, P = 0.04), lost more fat (PL 1.1 ± 0.5; PYR −0.4 ± 0.5 kg, P = 0.03), and tended to lose a greater percentage of body fat (PL 1.0 ± 0.7; PYR −0.65 ± 0.6%, P = 0.07), with no differences observed in fat-free mass (PL 0.1 ± 0.5; PYR 0.7 ± 0.3 kg, P = 0.29). However, these changes were not significant when body composition data were analyzed by MANOVA (P = 0.16). There was some evidence that PYR may negate some of the beneficial effects of exercise on HDL values. No significant differences were observed between groups in maximal exercise responses or metabolic responses to submaximal walking.
Conclusions: Results indicate that PYR supplementation during training does not significantly affect body composition or exercise performance and may negatively affect some blood lipid levels

Utilização da fração semipurificada da proteinase do Trypanosoma cruzi no imunodiagnóstico da doença de Chagas
Group 0 Rh negative human erytrocytes were coated with the semipurified fraction of T. cruzi proteinase and tested with sera both from patients with chagas' disease and from others with unrelated parasitic diseases. Positive haemagglutination reactions were only observed with the sera from the former and with that from two patients with mucocutaneous leishmaniasis. No crossed reactions were observed with visceral leishmaniasis, malaria, toxoplasmosis syphilis, schistosomiasis or mononucleosis sera. Results suggest that this purified fraction can be used in immunodiagnosis of American Trypanosomiasis.Foram sensibilizadas hemácias humanas 0 Rh negativo com a fração semipurificada (Fp) da proteinase do Trypanosoma cruzi, e testadas quanto a antigenicidade com soros de pacientes portadores de tripanossomÃase americana crônica e de outras doenças parasitárias não relacionadas. Reações de hemaglutinação positivas foram observadas com os soros de pacientes chagásicos e com alguns soros de indivÃduos portadores de leishmaniose cutaneo-mucosa. Não foram observadas reações cruzadas com os soros de pacientes portadores de leishmaniose visceral, malária, toxoplasmose, sÃfilis, esquistossomose e mononucleose. Os resultados obtidos são favoráveis ao emprego desta fração antigênica em testes de imunodiagnóstico da tripanossomÃase americana
A conceptual social media tool for supporting collaborative university-industry R&D programs
This paper aims to help professionals and academics involved in collaborative university-industry RD programs and projects, by presenting a conceptual social media tool that can be used to improve communication and collaboration between internal stakeholders. The social media tool conceptualization was developed based on a case study research strategy. The case selected was a large publicly funded RD collaborative program that covers 30 RD projects carried out by a university and an industry partner. During the case study analysis three research methods were applied: participant observation, document analysis, and focus groups. The social media tool is conceptualized in seven functional building blocks: identity, relationships, sharing, presence conversations, reputation and groups. For each building block, its main objectives and requirements are detailed, within this particular context of collaborative university-industry RD programs and projects.This research is sponsored by the Fundação para a Ciência

A fabric-based soft hand exoskeleton for assistance: the ExHand Exoskeleton
INTRODUCTION: The rise of soft robotics has driven the development of devices for assistance in activities of daily living (ADL). Likewise, different types of actuation have been developed for safer human interaction. Recently, textile-based pneumatic actuation has been introduced in hand exoskeletons for features such as biocompatibility, flexibility, and durability. These devices have demonstrated their potential use in assisting ADLs, such as the degrees of freedom assisted, the force exerted, or the inclusion of sensors. However, performing ADLs requires the use of different objects, so exoskeletons must provide the ability to grasp and maintain stable contact with a variety of objects to lead to the successful development of ADLs. Although textile-based exoskeletons have demonstrated significant advancements, the ability of these devices to maintain stable contact with a variety of objects commonly used in ADLs has yet to be fully evaluated. MATERIALS AND METHODS: This paper presents the development and experimental validation in healthy users of a fabric-based soft hand exoskeleton through a grasping performance test using The Anthropomorphic Hand Assessment Protocol (AHAP), which assesses eight types of grasping with 24 objects of different shapes, sizes, textures, weights, and rigidities, and two standardized tests used in the rehabilitation processes of post- stroke patients. RESULTS AND DISCUSSION: A total of 10 healthy users (45.50 ± 14.93 years old) participated in this study. The results indicate that the device can assist in developing ADLs by evaluating the eight types of grasps of the AHAP. A score of 95.76 ± 2.90% out of 100% was obtained for the Maintaining Score, indicating that the ExHand Exoskeleton can maintain stable contact with various daily living objects. In addition, the results of the user satisfaction questionnaire indicated a positive mean score of 4.27 ± 0.34 on a Likert scale ranging from 1 to 5

Biochemical and microbiological analysis of the saliva of institutionalized elderly : with edentulism, use of dentures and presence of biofilm
To analyze biochemical and microbiological parameters of the saliva of institutionalized elders and to investigate the relation of these parameters with edentulism, use of dentures and presence of biofilm. A cross-sectional study carried was out in seven long-term institutions. Samples (n=161) of unstimulated saliva were collected for analysis of salivary flow, quantification of total proteins and identification of microorganisms. Oral examination was carried out to verify the number of missing teeth, the use of dentures and the presence of visible biofilm on the surface of teeth and dentures. Associations were performed using chi-square or Fisher?s exact test (?0.05). Associations were observed between the presence of dentures biofilm and the colonization of Streptococcus sp. (p=0.038) and Candida sp. (p=0.03). The absence of teeth and use of dentures do not influence the amount of total proteins and the microorganisms count in saliva. Denture biofilms are associated with the presence of Streptococcus sp. and Candida sp. in saliva of institutionalized elders
