RESUMEN

This study compares the physicochemical characteristics of breast meat (Pectoralis major) from conventional chicken and free-range chicken production systems. Analyses of pH, instrumental color measurement, weight loss from cooking (WLC), and water retention capacity (WRC) were carried out. Average pH values were slightly higher for conventional chicken samples. WLC did not show a significant difference between conventional and free-range chicken samples. The WRC was better and higher for the free-range chicken samples than the conventional ones. The mean values for luminosity (L*) were within the normal range, with slightly higher values for conventional chicken. In chromatids a* and b*, there was a tendency towards a more reddish color for free-range chicken samples. The differences found for types of production can be explained mainly by the difference in age at slaughter, the degree of physical activity, animal feeding, among other characteristics that differentiate an animal raised by the extensive system from the intensive system.

RESUMEN

Strawberry (Fragaria x ananassa Duch.) is a highly perishable fruit whose characteristics make it susceptible to developing microorganisms. Plant extracts have been studied as an alternative to pesticides to control spoilage microorganisms, responding to the expectation of the population seeking a healthier way of life. The fungus Botrytis cinerea is a facultative pathogen of vegetables, which can affect all stages of the development of several fruits, such as the strawberry, where it causes gray rot. Trichilia catigua (catuaba), Paullinia cupana (guarana), Stryphnodendron barbatiman (barbatimão), and Caesalpinia peltophoroides (sibipiruna) are planted in the Brazilian flora and have demonstrated pharmacological properties in their extracts. This work aimed to treat strawberries with a biodegradable film containing extracts of these species to evaluate strawberry conservation. There were notable distinctions in mass loss between the extract-treated and control samples. The pH, total acidity (TA), and soluble solids parameters exhibited consistently significant means across both sets of samples. Luminosity increased over the course of days in the color parameters, with the exception of strawberries coated with guarana. The red color showed greater intensity, except for those coated with barbatimão extract. Considering the results, it is possible to conclude that the coatings used can become an alternative to enhance the conservation of strawberries.

RESUMEN

Ivermectin is a safe and effective drug in humans and has been approved for use in numerous parasitic infections for over 50 years. In addition, many studies have already shown its antiviral activity. Ivermectin is generally well tolerated, with no indication of central nervous system-associated toxicity at doses up to 10 times the highest FDA-approved dose of 200 µg/kg. The in vitro results of ivermectin for reducing SARS-CoV-2 viral load are promising and show that Ivermectin kills SARS-CoV-2 within 48 hours. A hypothesized mechanism of action for this drug is a likely inhibition of IMPα/ß1-mediated nuclear import of viral proteins as demonstrated for other RNA viruses. However, controlled and randomized studies are needed to prove its effectiveness in COVID-19 in humans. In a single in vivo study with published results, patients confirmed to be infected with SARS-CoV-2 received at least one dose of ivermectin at any time during hospitalization. The use of ivermectin was associated with lower mortality during treatment with COVID-19, especially in patients who required increased inspired oxygen or ventilatory support. Additionally, 81 studies with the clinical use of ivermectin in humans are being carried out worldwide according to ClinicalTrials.gov. However, none of these data has been published so far. However, private and public entities in Brazil have been adopting this drug in their protocols as prophylaxis and in the initial phase of the disease. In addition, ivermectin has been used in mass treatment to prevent onchocerciasis and lymphatic filariasis in sub-Saharan Africa for many years. Surprisingly, this region has the lowest proportional mortality rate among the continents, despite the increasing numbers of infected people released by the World Health Organization.

A ivermectina é um fármaco seguro e eficaz em seres humanos e é aprovado para uso em inúmeras infecções parasitárias há mais de 50 anos. Além disso, muitos estudos já evidenciaram sua atividade antiviral. A ivermectina é geralmente bem tolerada, sem indicação de toxicidade associada ao sistema nervoso central para doses até 10 vezes a dose mais alta, aprovada pelo FDA (Food and Drug Administration), de 200 µg/kg. Os resultados in vitro da ivermectina para redução da carga viral do SARS-CoV-2 são promissores e mostram que a Ivermectina mata o SARS-CoV-2 dentro de 48 horas. Uma hipótese de mecanismo de ação para esta droga é uma provável inibição da importação nuclear de proteínas virais mediada por IMPα / ß1 como demonstrado para outros vírus de RNA. No entanto, estudos controlados e randomizados são necessários para comprovar sua eficácia na COVID-19 em humanos. Em um único estudo in vivo com resultados publicados, pacientes confirmadamente infectados por SARS-CoV-2 receberam pelo menos uma dose de ivermectina em qualquer momento durante a hospitalização. A utilização da ivermectina foi associada a menor mortalidade durante o tratamento com COVID-19, especialmente em pacientes que necessitaram de maior oxigênio inspirado ou suporte ventilatório. Adicionalmente, 81 estudos com o uso clínico da ivermectina em humanos estão sendo realizados em todo o mundo segundo o site ClinicalTrials.gov. Porém, nenhum destes teve seus dados publicados até o momento. No entanto, entidades privadas e públicas no Brasil vêm adotando este medicamento em seus protocolos como profilaxia e na fase inicial da doença. Além disto, a ivermectina é utilizada no tratamento em massa na prevenção da oncocercose e filariose linfática na África subsaariana há muitos anos. Surpreendentemente, esta região possui o menor índice de mortalidade proporcional entre os continentes, apesar dos números crescentes de contaminados divulgados pela Organização Mundial da Saúde.

RESUMEN

Tilapia has high-temperature tolerance, can breed in captivity, grow fast, and have excellent cost-benefit. Because of these characteristics, this species is of great interest in aquaculture and, currently, the most produced fish in Brazil. However, by increasing tilapia production, there was also a rise in the amount of organic waste, mainly from filleting, which discards 70% of waste. There are many studies on collagen extraction from tilapia skin as an alternative to reduce these residues and add commercial value. In this work, the extraction of protein concentrate was tested using an acid protocol, in which the tilapia skins underwent a pre-treatment in an acid medium and saline precipitation, with variations in time and concentration. After its extraction, the skin was evaluated for ash, moisture, protein, solubility, and pH. The protein concentrate obtained showed low ash contents, and the humidity is within those presented by the literature. The protein concentrate showed levels from 68.73 to 80.58% of protein and a low solubility between 4.03 to 6.93%. In conclusion, acid extraction is a possible means of collagen extraction, and tilapia skin is a good alternative to reuse waste generated in the fish industry.

A tilápia tem tolerância a altas temperaturas, pode se reproduzir em cativeiro, crescer rápido e tem excelente custo-benefício. Por essas características, esta espécie é de grande interesse na aquicultura e, atualmente, o pescado mais produzido no Brasil. No entanto, com o aumento da produção de tilápias, houve também um aumento na quantidade de resíduos orgânicos, principalmente da filetagem, que descarta 70% dos resíduos. Existem muitos estudos sobre a extração de colágeno da pele de tilápia como alternativa para reduzir esses resíduos e agregar valor comercial. Neste trabalho, a extração do concentrado protéico foi testada utilizando um protocolo ácido, no qual as peles de tilápia foram submetidas a um pré-tratamento em meio ácido e precipitação salina, com variações de tempo e concentração. Após sua extração, a pele foi avaliada quanto a cinzas, umidade, proteína, solubilidade e pH. O concentrado protéico obtido apresentou baixos teores de cinzas, e a umidade está dentro dos apresentados pela literatura. O concentrado protéico apresentou teores de 68,73 a 80,58% de proteína e uma baixa solubilidade entre 4,03 a 6,93%. Em conclusão, a extração ácida é um possível meio de extração de colágeno, e a pele de tilápia é uma boa alternativa para reaproveitar os resíduos gerados na indústria de pescados.

RESUMEN

The search for healthy foods has attracted the industry's attention to developing products that use natural ingredients, including natural antioxidants. Antioxidants act as free radicals or oxygen scavengers, inhibiting lipid oxidation and adversely affecting meat products' sensory and nutritional quality. Several synthetic antioxidants have been used in the meat industry; however, studies point to health risks related to their consumption. Such fact drives research into natural antioxidants extracted from grains, oilseeds, spices, fruits, and vegetables, which may have a health-promoting effect. This manuscript evaluates the effectiveness of several natural antioxidants in improving the quality and shelf life of chicken meat products during processing, storage, and distribution. The potential effects of natural antioxidants widely used in chicken products are also discussed. It can be concluded that these natural antioxidants are possible substitutes for synthetic ones. However, their use can affect the product's characteristics.

RESUMEN

The evolution of beauty market and personal care is constant in Brazil as well in the rest of the world. Technological advances have brought up nanotechnology to the cosmetological field, employing active principles at atoms enveloped by vesicles, in order to take the active principle precisely to the target tissue to optimize the results achieved because of the considerable ease to cross skin barriers. Manufacturing of nanotechnology cosmetics is confronted with low absorption capacity. One of the many active principle found in cosmetic industry is caffeine, a pseudoalkaloid from the xanthine group used as a stimulant with the mechanism of the lipolytic action. This active is widely used in a esthetics and cosmetics field in treatments involving dysfunctions such as localized fat and fibroedema geloid. To work out perfectly, the principle active need to interact and create a set of factors that includes lipolysis intensification. The caffeine encapsulation in gel-based nanocosmetics has the purpose of taking this active up to the adipocyte, the target cell, for mentioned dysfunctions treatment. Thus, we aim to present a review of how has been, the use of caffeine in the production of cosmetics.(AU)

RESUMEN

As there is a great scarcity of studies on the importance of good compounding practices in the preparation of cosmetics, this study aimed to evaluate the quality control of cosmetics with active ingredient caffeine for the treatment of cellulite prepared by magistrals pharmacies. Microbiological analyzes, pH determination, color measurement, quantification of the percentage of the active ingredient caffeine and viscosity in creams and gels with 5% of the active ingredient caffeine were performed. In the microbiological analysis, the presence of molds and yeasts was verified above the permitted level according to the Brazilian pharmacopoeia. The pH decreased over time, contributing to the formulations becoming more acidic. In the color parameters, it was found that pharmacy F4 showed a brownish color, both for the gel and for the cream. The percentage of caffeine was within specifications in all formulations and the viscosity remained unchanged during the shelf life of the samples. It is important that the compounding pharmacies demand more effectively the commitment of the team, as well as the analysis of the raw material according to the microbiological control regulations to translate into the quality of the products prepared by the pharmacies and favor the consumer in the effective objective that the product you want to achieve.(AU)

Como há uma grande escassez de estudos sobre a importância de boas práticas de manipulação na elaboração de cosméticos, o presente estudo teve como objetivo avaliar o controle de qualidade de cosméticos com princípio ativo cafeína para o tratamento de celulite, elaborados por farmácias de manipulação de Campo Mourão. Foram realizadas análises microbiológicas, determinação do pH, mensuração da coloração, quantificação da porcentagem do princípio ativo cafeína e viscosidade em cremes e geís com 5% do princípio ativo cafeína. Nas análises microbiológicas foi verificada a presença de bolores e leveduras acima do pemitido segundo a farmacopéia brasileira. O pH diminuiu ao longo do tempo, contribuindo para que as formulações ficassem mais ácidas. Nos parâmetros de cor averiguou-se que a farmácia F4 apresentou uma coloração amarronzada, tanto para o gel quanto para o creme. A porcentagem de cafeína estava dentro das especificações em todas as formulações e a viscosidade se manteve inalterada durante o prazo de validade das amostras. Com o propósito de um melhor preparo magistral é importante que as farmácias de manipulação exijam de forma mais eficaz o comprometimento da equipe, bem como a análise da matéria-prima segundo as regulamentações de controle microbiológico. Além disso, a implementação de normas mais rígidas e o melhor controle da matéria-prima e das formulações finais fazem com que a qualidade dos produtos manipulados pelas farmácias magistrais seja aumentada significativamente, favorecendo o consumidor na efetiva finalidade a que o produto objetiva atingir.(AU)
