Effects of isokinetic eccentric training on knee extensor and flexor torque and on gait of individuals with long term ACL reconstruction: A controlled clinical trial

Abstract-This study investigated the effects of the isokinetic eccentric training (IET) on the knee extensor and flexor torque and kinematic gait parameters in individuals with ACL reconstruction. Sixteen men with ACL reconstructed (ACLr) whose torque and the gait were evaluated, before and after 12 weeks of IET, was compared to a control group (14 individuals). Student t, MANOVA and ANOVA tests were performed with 5% of significance. The training increased the isometric, concentric at 30 and 120º/s (p < .05) and eccentric at 30º/s (p < .01) extensor torque on the affected limb (AL), and eccentric at 30 and 120º/s (p < .01), on the non-affected limb (NAL). In the flexors, there was an increase on the torque: isometric, concentric at 30º/s and eccentric at 30 and 120º/s (p < .01) in AL and in eccentric at 30 (p < .05) and 120º/s (p < .01) in NAL. With respect to the angular and spatio-temporal variables gait, there was no difference between pre-and post-training in LCAr group. Compared to control group, the cycle time, in two members, was lower in LCAr group, and stride length and cadence were higher in the AL of the LCAr (p < .05). Moreover, the knee flexion-extension angles (minimum and maximum) remained lower in LCAr, pre-and post-training (p < .01). The torque gain associated with eccentric isokinetic training did not affect the kinematic parameters of gait in patients undergoing ACL reconstruction.

Este estudo investigou os efeitos do treinamento isocinético excêntrico (TIE) sobre o torque extensor e flexor do joelho e parâmetros cinemáticos da marcha de indivíduos com reconstrução do LCA. Dezesseis homens com LCA reconstruído (LCAr), foram avaliados quanto ao torque e marcha, antes e após 12 semanas de TIE e comparados com um grupo controle (14 indivíduos). Testes t Student, MANOVA e ANOVA foram realizados com 5% de significância. O treinamento aumentou o torque extensor isométrico, concêntrico a 30 e 120º/s (p < 0,05) e excêntrico a 30º/s (p < 0,01) no membro afetado (MA), e excêntrico a 30 e 120º/s (p < 0,01), no membro não afetado (MNA). Nos flexores, houve um aumento no torque: isométrico, concêntrico a 30º/s e excêntrico a 30 e 120º/s (p < 0,01) no MA, e excêntrico a 30 (p < 0,05) e 120º/s (p < 0,01) no MNA. Com relação às variáveis espaço-temporais e angulares da marcha, não houve diferença entre as avaliações pré e pós-treino no grupo LCAr. Comparado ao controle, a duração do ciclo, nos dois membros, foi menor no LCAr, e comprimento da passada e cadência foram maiores no MA do grupo LCAr (p < 0,05). Além disso, os ângulos (mínimo e máximo) de flexão-extensão do joelho permaneceram menores no LCAr, pré e pós-treino (p < 0,01). O ganho de torque associado ao treinamento isocinético excêntrico não modificou os parâmetros cinemáticos da marcha nos indivíduos submetidos à reconstrução do LCA.

Beekeeping in Brazil: A Bibliographic Review

Brazil presents favorable conditions for beekeeping, having a suitable climate; native flowering plants with great potential for the production of honey, pollen, propolis, and royal jelly; and bees adapted to our conditions, tolerant to the main apicultural diseases and highly productive. Through the meliponiculture, the conservation of mainly native forest areas is allowed; therefore, they are the best environments for the creation of native bees and production of by-products of the beehive with quality. The stingless bees are very sensitive to any disturbance due to anthropogenic action. A systematic bibliographical review was carried out in different electronic databases, through descriptors referring to beekeeping in Brazil. The identification of articles and their inclusion occurred between January 2018 and April 2018. The bibliographic research was conducted in the following electronic databases: (1) Scientific Electronic Library Online (SciELO), (2) Public Library of Science (PLOS) Biology, and (3) ScienceDirect. In order to help in the process of standardization of bee products and traceability of the production chain, it was possible to draw a profile of the main bioactive substances of the beehive products of Brazil. It was also possible to relate the benefits of an adequate management of beekeeping and meliponiculture in Brazil

Epidemiological aspects and oral implications of Paracoccidioidomycosis infection: an integrative review

Paracoccidioidomycosis (PCM) is a systemic mycosis caused by the dimorphic fungus Paracoccidioides brasiliensis. It represents a significant infection in South America, occurring mainly in tropical and subtropical countries such as Brazil. Oral mucosal lesions, which are the most important symptom in dentistry, may be the first visible physical manifestation of the disease, often preceding even pulmonary lesions. This study aims to carry out an integrative literature review to identify the main epidemiological aspects and oral implications of Paracoccidioidomycosis (PMC) infection. A search was carried out in the PubMed, LILACS and SciELO databases and, after applying the inclusion, exclusion, eligibility and thematic relevance criteria, 18 articles were selected for analysis in this study. Paracoccidioidomycosis (PCM) is endemic in Brazil and mainly affects middle-aged and elderly men and occurs in rural areas. It is a systemic disease where clinical manifestations are often added to oral lesions. Dentists play a key role in identifying these lesions, in the correct diagnosis and treatment of this disease. Making PCM notification compulsory in Brazil is essential.Paracoccidioidomycosis (PCM) is a systemic mycosis caused by the dimorphic fungus Paracoccidioides brasiliensis.

Rosemary extract and celery-based products used as natural quality enhancers for colonial type salami with different ripening times

This study aimed to evaluate the use of rosemary (Rosmarinus officinalis) extract (RE), celery (Apium graveolis), and low levels of NO3 and NO2 as natural agents to enhance the quality of colonial salami. Salami was produced according to three treatments: (A) Control: 0.1% curing salt; (B) Rosemary: 0.05% curing salt + 0.5% RE (rosemary extract); and (C) Rosemary+celery: 0.14% Veg 503 + 0.27% Veg 504 (sea salt plus celery) + 0.5% of RE (rosemary extract). There was no effect (P &gt; 0.05) of the treatments on water activity, Na content, and residual NO3 and NO2. Fatty acids C18:2 and C20:4 were reduced (P < 0.05) during the ripening period in the Control treatment indicating possible oxidation. The use of celery resulted in lower pH values (P < 0.05) in the salami. Reduced addition of NO3 and NO2 resulted in salami lighter in color (higher L* values, P < 0.05) at the 12th day of ripening. In conclusion, celery-based products proved to be an effective source of NO2 and NO3 for color development, but the low pH of the product indicates the need for better evaluation of its use in fermented salami. The RE (rosemary extract) reduced fat oxidation in salami, but this needs further evaluation

Foram produzidos salames de acordo com três tratamentos: (A) Controle: 0,1% de sal de cura; (B) Alecrim: 0,05% de sal de cura + 0,5% de EA; (C) Alecrim+aipo: 0,14% de Veg 503 + 0,27% de Veg 504 (sal marinho e aipo) + 0,5% de EA. Não houve efeito (p > 0,05) dos tratamentos sobre o conteúdo de Na, atividade de água e NO3 e NO2 residuais. Houve redução (p < 0,05) dos ácidos graxos C18:2 e C20:4 durante o período de maturação no tratamento Controle, indicando sua possível oxidação. O uso do aipo resultou em baixo (p < 0,05) pH no salame. A redução da adição de NO3 e NO2 resultou em salames com coloração mais clara (valores de L* mais elevados, p < 0,05) aos 12 dias de maturação. Conclui-se que o aipo foi efetivo como fonte de NO3 e NO2 para desenvolvimento da cor, mas o baixo pH do produto indica a necessidade de melhor avaliar sua utilização em salames fermentados. Os salames produzidos com EA poderão apresentar diferencial de qualidade pela menor oxidação das gorduras, mas isto necessita ser confirmado em estudo futuros

Sensory and physicochemical characteristics of salamis added with vegetable-based curing ingredients

ABSTRACT: The aim of this study was to evaluate the sensory and physicochemical quality of colonial salamis added with vegetable-based curing ingredients as potential enhancers of quality products. Salamis were produced according to three treatments: (A) Control: 0.1% curing salt; (B) rosemary: 0.05% curing salt + 0.5% rosemary extract (RE); and (C) RE+celery: 0.14% Veg 503 + 0.27% Veg 504 (sea salt plus celery, nitrate and nitrite supplies, respectively) + 0.5% of RE. No significant differences were observed (P>0.05) among the three treatments for dry matter (DM), crude protein (CP), ash, ether extract (EE) and gross energy (GE). Sensory analysis was performed by applying the preference test and multiple comparison between the three treatments. Salamis added with vegetable-based curing ingredients were sensory equivalent to conventional level of curing salts. Vegetable extracts allowed the development of the sensory features of salami and did not interfere in the fermentation process. Results suggested that the extracts can serve as effective natural curing ingredients for the ripening process and cured meat color as well as adequate shelf-life replacing the commercial curing salts in meat and meat products. After 30 days of ripening, salami from the control treatment (conventional levels of nitrite and nitrate) and the treatments with added vegetable-based curing ingredients and low nitrite and nitrate content (RE and RE + celery) were equivalent in sensory quality
