Little is known about the early history of the chicken (Gallus gallus domesticus), including the timing and circumstances of its introduction into new cultural environments. To evaluate its spatio-temporal spread across Eurasia and north-west Africa, the authors radiocarbon dated 23 chicken bones from presumed early contexts. Three-quarters returned dates later than those suggested by stratigraphy, indicating the importance of direct dating. The results indicate that chickens did not arrive in Europe until the first millennium BC. Moreover, a consistent time-lag between the introduction of chickens and their consumption by humans suggests that these animals were initially regarded as exotica and only several centuries later recognised as a source of ‘food’.

Published: June 2022

Agricultural output growth is an everlasting realistic problem in human society. Rural finance aims to relieve the financing constraint and pressure on the rural society with capital scarcity through credit aid and support agricultural output growth. However, credit funds cannot be adequately input into agricultural production and management, which adversely impacts agricultural output. To accurately investigate the agricultural output effect of rural finance, using the 2015 China Household Finance Survey’s large-sample micro-survey data, an extended regression model (ERM) was established that could effectively eliminate the endogeneity problem. Then, the agricultural output effect of rural finance was empirically estimated. Subsequently, the robustness of empirical results was tested using the propensity score matching (PSM) method and the Kernel density map. Agricultural technical guidance was introduced to explore its regulating effect on the relationship between rural finance and agricultural output. Furthermore, the robustness test was conducted for different groups, such as the eastern region, the western region, and the central region, to investigate the regional differences in the agricultural output effect of rural finance. The estimation results of ERM indicate that rural finance exerts a significantly positive influence on the agricultural output, and a large estimated coefficient manifests the considerable agricultural output effect of rural finance. The estimation results of the PSM method show that rural finance significantly increases the agricultural output of all peasant household samples averagely by 11,100 CNY. Agricultural technical guidance has a significantly positive regulating effect on the agricultural output effect of rural finance. According to the regional heterogeneity analysis, rural finance is significantly promoted in central and western regions, but it presents an insignificant crowding-out effect in the eastern region. Conclusions in this study can provide pertinent enlightenment for strengthening the productive functions of rural finance and lay a theoretical foundation for facilitating its healthy development.

Published: June 2022

Business organizations and management encompass a wide range of aspects requiring research and analysis. Two key issues are communications management and employee participation promotion within firms. This study focused on the variables of communication and participation in organizational structure, business decision making, transmission of orders, supervision, and control in small and micro-enterprises in the Canary Islands, Spain. The research examined the two variables’ ability to generate increased involvement in and employee identification with their firm. The analytical framework applied sought to investigate Canarian managers’ criteria and priorities regarding using communication and participation as management tools. The methodology included the Rasch analysis technique. The study analyses seven variables considered relevant in relation to communication that are communication between management and workers, fluid and informal communication, use of information technology in internal communication, access of all workers to new information technology, linking/relationship systems between units of the same level, linking/relationship systems between units of different levels and the existence of information disseminated as a tool. Likewise, among the variables related to participation, twelve variables recognized as relevant in the literature are analysed. These variables are setting specific objectives for workers, individual initiative, cooperation, decentralization of decision making, control, participation in decision making, participation in setting objectives, workers' autonomy in decision making when carrying out their work, initiative in their work, control of their work, commitment and involvement of managers in daily work and delegation of authority to lower levels. The predominance of small businesses, in many cases managed by their owners, allows us to appreciate a vertical communication based on direct supervision, from top to bottom. The results reveal a poorly balanced combination of communication and participation systems in Canarian firms. These marked imbalances have consequences for managers’ coordination mechanisms and potential for effectively managing their firms.

Authors: Bartók Ottó , Matošková Jana
Published: June 2022

E-commerce has become an integral part of the modern age. The behaviour of e-commerce customers has some specifics, which is useful for firms to understand. As customers’ trust and willingness to accept risk influence the decision to buy a product in e-commerce, it is evident that some unique factors must be in e-commerce which is needed to pay attention to be a successful seller. One of the trends affecting how to manage relations with customers is the use of firm profiles on social networks. This paper identifies factors related to the company’s Facebook profile that influence customer Satisfaction and Loyalty in e-commerce. Furthermore, non-traditional factors such as Self-efficacy or Data security are used. The study provides a primary basis for further research in this area. Data collection was done among e-commerce customers using a questionnaire survey (n = 602). For data analysis, structural equation modelling (SEM) was used. The determined construct contained a total of 9 variables. The findings confirmed that the following factors affect customer satisfaction and loyalty: the perceived usefulness and the amount of information on the Facebook company profile, the perceived Credibility of information given on this profile, the Data security offered by the social network, customer Self-efficacy and Ease of use of the given social network. The results supported the idea that it is possible to build relationships with customers in e-commerce via social networks. To offer credible information in an adequate frequency on the company profile is essential. Furthermore, it is helpful to consider customers’ perceived safety and Self-efficacy, which have also proven to be important in the online environment. These results can serve business practice.
Estudio diacrónico de los adverbios relativos de lugar en un corpus de textos medievales
Authors: González Santolalla Míriam
Published: June 2022

Este trabajo se centra en el estudio de las construcciones encabezadas en español por los adverbios relativos de lugar, donde y adonde (a donde), herederos de un sistema latino que presentaba cuatro formas adverbiales: UBI (‘donde’), UNDE (‘de donde’), QUO (‘a donde’) y QUA (‘por donde’). El análisis de un corpus (siglos XIII-XV) nos permitirá conocer el reagrupamiento de los sentidos locativos y la evolución de los adverbios que los expresan en la historia del español. Esta evolución está condicionada por la pérdida de especificidad en la expresión del lugar, la necesidad de motivar el valor locativo de estos nexos y la intervención de determinados elementos morfosintácticos.
Nouns of Lithuanian Slang with the Slavic suffixes: Borrowings and Hybrids
Authors: Kudirka Robertas
Published: June 2022

The article analyses 200 nouns of Lithuanian slang with the three most common Slavic suffixes: -ka, -kė (Russ. -ка, Pl. -ka); -akas (Russ. -ак, Pl. -ak), -iakas (Russ. -як); -ščikas, -čikas (Russ. -щик, -чик). The majority of nouns in the slang are with the suffixes -kė, -ka. A part of the borrows with theses suffixes are the result of suffix univerbation; the univerbs usually are informal or slang words in Russian language. The borrowings with the suffixes -akas, -iakas are the second most common: these nouns are mostly slang words in Russian. There are many hybrids created with the suffixes -akas, -iakas in Lithuanian slang. The nouns with the suffixes -ščikas, -čikas are the third most common; the words with -ščikas are more ordinary in slang; the suffix -čikas is less common, but both forms are often used as synonyms. There are also few pseudo-borrowings with Russian roots and suffixes -ščikas, -čikas as well as hybrid derivatives.

Model problems on the separation of charge-carrying components into two streams using a membrane in a cell of a dialysis apparatus are considered. For a brighter detection of the separation effect, the components are taken such that they differ markedly from each other in the mass of ions and diffusion coefficients. The convective-diffusion process of transition of ions through membranes with different physical features that create resistance to the transition is considered. As a result of the solution, the potential and component distributions were obtained in the cell volume of the dialysis apparatus as a function of time. It was shown that a quasi-equilibrium state is established relatively quickly in the capillary and the membrane, which determines the ratio of the flow rates of the components in the cell channels.

The effect of modifying dispersed compositions on the grain structure and mechanical properties of industrial aluminum alloys is studied. Aluminum alloys of the Al-Mg, Al-Mg-Sc systems were modified with dispersed SiC powder with a particle size of up to 200 nm. Calculated the amount of modifier to enter into the melt. The physicochemical properties of dispersed SiC were studied. The melting of alloys AL4S, 1570, 2219, AK9ch in the initial state and with the processing of SiC melts was carried out. The dependences of the particle size and amount  of the    modifier   on the   mechanical  properties  of      the  alloys  are   established. The mechanism of interaction of the modifier with the aluminum melt during crystallization is established. In industrial experiments, the most effective particle size of SiC was found to increase the σт of the AK9ch alloy from 115 to 260 MPa in the cast state. The optimal SiC content (0,10%) was determined to increase the σt of aluminum alloys.

Published: June 2022

ABSTRACT The present study aimed to analyze the possible routes of Fusarium spp. introduction in Madeira between 1990 and 2018 and to elucidate the factors that favored the introduction and settling of this fungus in the Island. Phytosanitary surveys were carried out in several crops and plants imported to Madeira. The isolates of Fusarium spp. were obtained from underground and aerial organs of the plants and cultured on differential media for species identification. Fungal colony and spore morphology were observed under a microscope and identified based on bibliography and dichotomous keys. The phytosanitary analysis for the incidence of Fusarium spp. in plants or crops indicated an increasing trend in the number of fungi, especially between 1990 and 2001. The greatest fungal contamination occurred in the municipalities located in the southern coast of the Island. Most of the contaminated samples were from Portugal (96.9%), while 0.1% to 1.6% samples derived from foreign countries, especially the Netherlands and France. Of 3,246 samples infected with Fusarium spp., 1,212 were from horticultural (37.3%), ornamental (36.9%), tropical and subtropical (16.9%), and temperate plants (9.9%). Fusarium wilt (Panama Disease) caused by F. oxysporum f. sp. cubense occurred in several products imported to Madeira. Other species like Fusarium oxysporum were also detected in several plants and agricultural products, along with Fusarium sp. and Fusarium equiseti. The geoclimatic conditions of Madeira can be suitable for the development and dispersion of these fungi. The trade of cultivars and plants from Portugal and from foreign countries has been an important route of Fusarium introduction in Madeira.

Ao final, pretende-se ter demonstrado não só como Williams colocou em questão suas origens e as singularidades da cultura e da política do País de Gales, mas também como o enfrentamento desses problemas impactou na construção de sua obra, contribuindo para a conformação do referencial teórico e da abordagem crítica do escritor.
CIBERESPAÇO E DESCENTRAMENTO: A CONSTITUIÇÃO SUBJETIVA COMO QUESTÃO DE ESPAÇO E TEMPO
Authors: Marzochi Samira Feldman
Published: June 2022

Resumo O presente artigo analisa, sob a abordagem pós-estruturalista e no quadro de uma sociologia do inconsciente, a constituição da subjetividade política mediada pelas tecnologias digitais. Trata-se de uma investigação eminentemente teórica, sem intuito de revisão bibliográfica sobre mídias, que recupera pressupostos fundantes das ciências sociais e da psicanálise para questionar a noção corrente, segundo a qual as mídias digitais, por si mesmas, produziriam novas subjetividades. Para tanto, a pesquisa desvia levemente o olhar dos aplicativos, plataformas e algoritmos, para privilegiar seus contornos, as relações sociais que são o objeto primordial da análise sociológica. Expressões de contextos históricos, econômicos, sociais e culturais mais abrangentes, porém dotadas de alguma margem de liberdade, as relações sociais, em última instância, seriam capazes de determinar as referências tempo-espaciais dos indivíduos e possibilitar o descentramento, condição da constituição subjetiva. É por meio de seus usos, e das relações que as constituem, que as mídias digitais condensam as características de seu tempo (primazia da categoria espaço, instantaneidade, simultaneidade, imanência, fragmentação, ausência de profundidade), assim como guardam a potencialidade de transcendê-lo.

Resumo O Tribunal Penal Internacional foi criado para julgar crimes contra os direitos humanos, contando com amplo apoio e participação de países africanos desde sua criação até os primeiros casos referidos. Essa posição de apoio, contudo, tem se revertido recentemente em alguns Estados. Esta pesquisa busca evidenciar quais as razões mobilizadas para a mudança de uma postura de apoio para uma postura de rechaço ao mecanismo. Acredita-se que a natureza do Tribunal e sua dupla agência jurídica e política geram impasses que agravam o descontentamento de Estados marginalizados internacionalmente, e que é essencial a atenção a esses problemas pela literatura de Relações Internacionais. Para tanto, foi realizado um levantamento de documentos oficiais de Estados africanos contrários, como discursos, iniciativas políticas e normativas, os quais foram interpretados à luz da literatura recente sobre o tema e à luz da discussão sobre a colonialidade do direito.

Published: June 2022

ABSTRACT Pecan tree [Carya illinoinensis (Wangenh.) K. Koch] is a widespread species in the southern region of Brazil and commercially important for nut and wood production. Stem cankers in pecan trees negatively impact the orchard, but the biotic causes of cankers are usually not identified. Symptoms of stem canker were observed in about 60% of pecan trees from orchards in the states of Rio Grande do Sul and Paraná. Therefore, this study aimed to analyze the molecular and morphophysiological characteristics of fungi associated with pecan canker in orchards in southern Brazil and to confirm their pathogenicity in pecan seedlings. Samples from symptomatic stems were collected in different municipalities and possible causal agents were isolated. Molecular identification was performed by the Polymerase Chain Reaction technique for amplification of the EF-1α region and subsequent sequencing. The sequencing, followed by morphophysiological aspects of mycelial growth and colony pigmentation, allowed the identification of a species complex included in the Botryosphaeriaceae family. The isolates were classified as Lasiodiplodia theobromae, Pseudofusicoccum kimberleyense and Neofusicoccum parvum. Pathogenicity was tested by inoculating the isolates into pecan seedlings to evaluate the symptoms. All isolates caused canker in the stem, but there was variation in the severity. Therefore, different species of the Botryosphaeriaceae family are responsible for stem canker occurrence in pecan trees in the southern region of Brazil, but at different levels of injury. Thus, it is crucial to identify and understand the behavior of the fungal isolates to best control cankers in pecan orchards.

Published: June 2022

ABSTRACT. Alzheimer's dementia (AD) is a neurodegenerative disease. The mechanism of oxidative stress in AD is due to amyloid beta (Aβ) protein that aggregates to form plaques, which further triggers chronic inflammation and neuronal apoptosis. Purple sweet potato extract with the main content of anthocyanins is a potential antioxidant with a direct target on the amyloid cascade hypothesis. Objective: The research objective was to determine the role of purple sweet potato water extract as an antioxidant and anti-inflammatory in preventing apoptosis in order to provide a neuroprotective effect in d-galactose-induced rats. Methods: A total of 100 male Wistar rats with randomized posttest-only control group design that met the eligibility criteria were included in this study. The treatment group was given 200 mg/kg BW/day of purple sweet potato water extract on days 1–70. d-galactose induction was administered in the treatment and control groups on days 15–70. Results: The independent t-test showed that the mean tumor necrosis factor-α (TNF-α) levels in the treatment group (735.36±139.74) was significantly lower than that in the control group (896.77±152.52). The p53 and glial fibrillary acidic protein (GFAP) expressions of astrocyte cells in the treatment group were significantly lower than that in the control group. The brain-derived neurotrophic factor (BDNF) levels in the treatment group (498.13±121.47) were higher than that in the control (391.93±140.28), and there was a significant increase in spatial working memory in the treatment group (72.01±10.22) than the control (59.77±11.87). Conclusions: The neuroprotective effect of purple sweet potato extract is due to d-galactose induction resulting from decrease in TNF-α levels, p53 expression, and GFAP expression and increase in BDNF levels and spatial working memory.

Published: June 2022

ABSTRACT Introduction: Micro-osteoperforation is a minimally invasive technique that has been used to accelerate orthodontic tooth movement and reduce treatment duration. However, literature presents conflicting reports about this technique. Objective: To evaluate the effectiveness of micro-osteoperforations on the rate of canine retraction and expression of biomarkers in gingival crevicular fluid (GCF). Methods: This was a randomized clinical trial with split-mouth study design. Thirty adult subjects with age above 18 years (20.32 ± 1.96) who required fixed orthodontic treatment and extraction of maxillary first premolars were enrolled and randomly allocated to either the experimental or control group. Randomization was performed by block randomization method, with a 1:1 allocation ratio. The experimental group received three micro-ostoperforations (MOPs) distal to maxillary canine, using the Lance pilot drill. The retraction of maxillary canine was performed with NiTi coil-spring (150g) in both experimental and control groups. The primary outcome was the evaluation of canine retraction rate, measured on study models from the baseline to 16 weeks of canine retraction. Secondary outcomes were the estimation of alkaline and acid phosphates activity in GCF at 0, 1, 2, 3, and 4 weeks. Results: There was a statistically significant difference in the rate of canine retraction only after the first 4 weeks. Subsequently there was no statistically significant difference from the eighth to the sixteenth weeks between MOPs and control group. There was a statistically significant difference in alkaline and acid phosphates activity in GCF between MOPs and control groups during the initial 4 weeks of canine retraction. Conclusion: Micro-ostoperforation increased the rate of tooth movement only for the first 4 weeks; thereafter, no effect was observed on the rate of canine retraction during 8, 12 and 16 weeks. A marked increase in biomarker activity in the first month was observed.

Published: June 2022

ABSTRACT Introduction: There are different possibilities of orthodontic planning for cases with congenital absence of maxillary lateral incisors. This subject divides the opinion of orthodontists and oral rehabilitation clinicians, due to the advantages and disadvantages of each treatment option, which may involve opening spaces for future implants and/or prosthetic restorations, or closing the spaces by positioning the maxillary canines in the place of lateral incisors. The correct diagnosis and careful evaluation of each patient allow to determine the best therapeutic approach. This paper discusses the main topics to be considered when planning these cases. Objectives: To evaluate the main aspects related to orthodontic treatment planning in cases of congenital absence of maxillary lateral incisors, to aid the decision-making, with clinical and scientific basis.

Abstract Objective to identify and discuss the reasons that hinder or restrict transsexuals’ accessibility to primary health services. Method original research with a qualitative approach. Twelve semi-structured interviews were conducted with transsexuals between December 2018 and March 2019. Bardin’s thematic content analysis was used. Results the following thematic categories emerged from data analysis: Low resolution and multiple barriers to access of transsexuals to primary health care; Non-inclusion and self-exclusion: the explicit non-belonging to the Unified Health System. Conclusion and implication for practice the non-recognition of transsexuals as citizens with the right to access health care, abjections by the transsexual body, prejudice and lack of value are factors that restrict this population to health system. This difficulty reverberates in an important challenge to be overcome by transsexuals in the search for qualified care. For practice, it is understood the importance of bringing to the center of discussions, in all spheres of health care, issues about values, principles and social morals that are intertwined in health professionals’ conduct and performance.
FIELDS, WORLDS AND FIGURATIONS: USING ELIAS TO REVISIT DEPTH CONCEPTUAL IMAGERY AND EMANCIPATORY CRITIQUE
Authors: Hughes Jason , Saramago André , Dunning Michael , Hughes Kahryn
Published: June 2022

Abstract We centrally explore the significance of conceptual imagery, particularly ideas of ‘depth’ and its relationship to ideals of critique, emancipatory action, and conceptions of social structure and action. We consider how depth imagery is invoked in critiques of sociological thinkers understood to employ ‘flat’ social ontologies. We develop a three-way comparison between Pierre Bourdieu’s ‘field,’ Howard Becker’s ‘world,’ and Norbert Elias’s ‘figuration’ to argue that not only is the ‘flatness’ charge unwarranted in the case of Becker’s and Elias’s ontologies, but the axioms upon which it is made are static, substantialist, and reductively mechanistic. Drawing on the work of Elias, we consider the merits of alternative more dynamically oriented conceptual imagery, reflecting upon its implications for how we might revisit the ‘politics’ of figurational sociology and understandings of emancipatory critique more generally.
POPULISM VS COVID-19. CIVILIZING AND DECIVILIZING PROCESSES IN A TIME OF GLOBAL CATASTROPHE
Authors: Pratt John , Lutyens Daisy
Published: June 2022

Abstract What constitutes a “civilized society”? The Oxford Dictionary defines it as one that has reached “an advanced stage of human development in which people […] behave well towards each other and share a common culture.” Yes, but there is more to “being civilized” than this. Based on Norbert Elias’ The Civilizing Process, this paper examines how the rise of populism in leading Anglo-American societies has undermined many of the essential attributes of civilized societies. Although the emergence of COVID-19 further added to this decivilizing process, COVID-19 and populism oppose each other. The former shows the empty promises and fraud of the latter, which can only be defeated by belief in science and a strong (but accountable) central state authority. Despite damaging individuals and societies, COVID-19 ironically helps strengthen the civilising process and weaken populism.
“AQUI EU ME SINTO SUFOCADA”: TEMPO E ECONOMIA EM UM CONDOMÍNIO POPULAR DO PROGRAMA MINHA CASA MINHA VIDA (PMCMV)
Authors: Petti Daniela Ramos
Published: June 2022

Resumo O artigo aborda a experiência do reassentamento de pessoas removidas de favelas cariocas, a partir das transformações econômicas que impactam suas vidas. O Programa Minha Casa Minha Vida (PMCMV) produz novas configurações econômicas, na medida em que formas de trabalho e de gestão do dinheiro da casa são afetadas pelas novas condições de moradia. Interrupção de atividades produtivas praticadas na favela, novas contas e taxas a pagar, somadas a um contexto de crise, desemprego e desassalarização, constituem uma sensação de incerteza, traduzida como “sufocamento”, experienciada pelos sujeitos na vida cotidiana. De um ponto de vista etnográfico, discorro sobre as criativas estratégias desenvolvidas a partir das capacidades imaginativas dos sujeitos no contínuo processo de fazer a vida (“melhorar de vida”, “dar futuro aos filhos”), o que abarca projetar o futuro.
APRENDIZ DE FEITICEIRO - A PEDAGOGIA DA ANTROPOLOGIA DE MARCEL MAUSS
Authors: Rocha Gilmar , Tosta Sandra Pereira
Published: June 2022

Resumo Marcel Mauss (1872-1950) é considerado um dos fundadores da Antropologia Social francesa na primeira metade do século XX. Ele reuniu em torno de si um conjunto de pessoas, instituições, representações e práticas que marcaram a história da antropologia moderna desde então. Embora não tenha desenvolvido estudos específicos sobre a educação, sua experiência acadêmica, suas atividades políticas e culturais, sua obra, são fontes inquestionáveis de inspiração e de reflexão sobre processos de ensino e de aprendizagem. A partir da trajetória intelectual e pedagógica de Mauss, o texto destaca algumas de suas ações acadêmicas, pedagógicas e institucionais em torno da etnografia, dos museus, do corpo e da aprendizagem, visando contribuir para o diálogo da antropologia com a educação.
Um mosaico de experiências e narrativas sobre práticas coletivas na terapia ocupacional: considerações metodológicas
Authors: Allegretti Maitê , Magalhães Lilian
Published: June 2022

Resumo Na última década, estudos em terapia ocupacional têm enfatizado aspectos da construção coletiva em pesquisas narrativas que refletem sobre os preceitos éticos essenciais à anonimidade de participantes, ao mesmo tempo em que garantem o seu protagonismo. Este artigo discute um percurso metodológico pouco usado, qual seja, a narrativa construída por meio da colaboração não anônima entre participantes e pesquisadores, buscando identificar os desafios e as potencialidades da elaboração compartilhada. Para tanto, o artigo apresenta: 1. descrição das concepções do estudo e suas características gerais, notadamente os referenciais teóricos e metodológicos que sustentam a construção reflexiva, dialógica e coletiva das histórias; 2. potencialidades e dificuldades da abordagem participativa na construção de conhecimento em terapia ocupacional. Um dos pontos centrais da metodologia adotada, a revelação das identidades das participantes, que enfatiza a escrita das histórias em primeira pessoa, ainda não está consolidado nos desenhos atuais de estudos participativos realizados com terapeutas ocupacionais e pode ser considerado uma ação inovadora para o campo da terapia ocupacional. São apresentados os requerimentos da formação técnica, como as habilidades de comunicação e pactuação política, bem como os desdobramentos éticos e epistemológicos da experiência das profissionais. Ademais, cabe registrar que, ao narrar em primeira pessoa, sem pseudônimos, a trajetória das profissionais, enfrentamos diversos desafios, como a linha tênue entre vida pessoal e vida profissional, e também os compromissos sociais e consequências políticas das ações das participantes, além da exposição involuntária de terceiros, que não necessariamente autorizariam que suas ações fossem tornadas públicas.

Published: June 2022

Abstract Introduction: Education professionals are one of the most important occupational groups and represents one of the main parts of the economy of modern society. The vocal demands most mentioned by the teachers are talking while standing up, talking a lot and in a closed environment, which corresponds to the most frequent situations encountered in teaching. In addition, remaining in the standing position for a prolonged period may have repercussions on other systems and generate postural deviations, pain and reduced functionality. Objective: To verify changes in pressure pain threshold, in disability index and in craniocervical posture of female teachers with vocal and musculoskeletal complaints, and with normal larynx, after myofascial release - pompage. Methods: This study was a controlled and randomized clinical trial. The following procedures were performed: anamnesis, videolaryngoscopy, hearing screening, clinical and photogrammetric postural assessment using the SAPo® protocol, completion of the neck pain self-assessment protocol Neck Disability Index, and pain threshold in the cervical muscles using the Pain Pressure Threshold. Myofascial therapy with pompage had a total of 24 sessions of 40 min each, three times a week, in 28 teachers assigned to the study group (SG), and 28 to the control group (CG). Afterwards, the groups were reassessed. Results: The SG presented a significant improvement in the pain threshold of all the muscles evaluated, in the posture of most of the body segments evaluated, and in the cervical disability. In the CG there was a significant improvement in angle A2 after therapy. Conclusion: After myofascial release therapy with pompage, the subjects presented a reduction in cervical pain and in functional disability, an increase in pain threshold, and posture improvement.

Abstract Introduction: Physical inactivity negatively impacts the functional status of the elderly during aging. Objective: To describe the activity and participation profile of physically inactive elderly and to investigate associated factors. Methods: A cross-sectional study with physically inactive elderly, aged ≥ 60 years, both sexes, with good cognitive function and independent gait. Personal factors, clinical history, history of falls in the last year, and identification of activity and participation profiles were investigated. Nonparametric statistical tests (SPSS 20.0) were performed, considering p < 0.05 significant. Results: The elderly (n = 36) had a mean age of 72.5 years (±7.7). Most were women (78%), with one to four years of education (69%), retired (72%), referring episodes of falling (58%) and affected by two to four comorbidities (53%). In the activities and participation profile, most of the physically inactive elderly presented mild problems for: crawling, kneeling, squatting, walking long distances, walking on different surfaces, walking around obstacles, climbing, and using public transportation. However, kneeling, squatting, walking on different surfaces, and climbing represented higher percentages of elderly who presented some problem. The advancement of age (p = 0.045), female sex (p = 0.022), episodes of falls (p = 0.037), and comorbidities (p = 0.031) were identified as factors that can impact functioning. Conclusion: The physically inactive elderly presented a mild problem in activities and participation items that are more related to strength and walking. Elderly aged over 70, female, with episodes of falls and comorbidities were significantly associated with reduced or impaired functioning.

Abstract Members of the order Trypanorhyncha are cestode parasites that are frequently found infecting the muscles of several marine fish species, affecting fish health and resulting in consumers’ rejection. Seventy–five specimens of marine fish were freshly caught from boat landing sites at the Alexandria coast along the Mediterranean Sea in Egypt, including two Carangids, the greater amberjack Seriola dumerili and the gulley jack Pseudocarans dentex; two Serranids, the Haifa grouper Epinephelus haifensis and the mottled grouper Mycteroperca rubra. Forty-five fish were infected; the infection was recorded as blastocysts embedded in fish flesh. Blastocysts were isolated and ruptured; the generated plerocerci were described morphologically, where, four different species were recovered; Callitetrarhynchus gracilis, Callitetrarhynchus speciosus, Protogrillotia zerbiae, and Grillotia brayi. The taxonomic position of these parasites was justified by multiple-sequence alignment and a phylogenetic tree was constructed following maximum likelihood analysis of the 18s rRNA sequences of the recovered worms. The accession numbers MN625168, MN625169, MN611431and MN611432 were respectively assigned to the recovered parasites. The results obtained from the molecular analyses confirmed the morphological records of the recovered parasites. Since metacestodes are found in the musculature of infected fish specimens, it is necessary to remove these areas in the commercialization of fish.
