Peach Palm Fruit (Bactris gasipaes) Peel: A Source of Provitamin A Carotenoids to Develop Emulsion-Based Delivery Systems.

The peach palm fruit (Bactris gasipaes) peel is a byproduct after fruit consumption. The peel flour of two varieties (yellow and red) was separately obtained by hot air drying and was subsequently milled. The proximate analysis showed that the red variety exhibited higher protein, fat, and fiber contents than the yellow one. A higher carotenoid (836.5 ± 24.5 µg/g), phenolic compounds (83.17 ± 1.76 mg GAE/100 g), and provitamin A activity (33.10 ± 0.83 µg retinol/g) were found in the cooked red variety. The carotenoid and phenolic compositions were analyzed by HPLC-PDA-MS, finding ß-carotene and γ-carotene to be major compounds. The effect of thermal treatment increased the amount of these provitamin A carotenoids and lycopene, which were detected only in the red variety. Among phenolic compounds, procyanidin dimer (isomer I), feruloyl quinic acid, and several apigenin C-hexosides were identified as major constituents of peach palm epicarp. A carotenoid-rich emulsion-based delivery system was obtained after the optimization (RSM model) of carotenoid extraction with ultraturrax and sunflower oil and further development of an ultrasound-assisted emulsion. The best conditions for a stable emulsion were 73.75% water, 25% carotenoid-rich oil extract, 1.25% emulsifiers, and 480 W of ultrasonic power for 5 min. The optimized emulsion had a total carotenoid content of 67.61 µg/g, Provitamin A activity of 3.23 ± 0.56 µg RAE/g, droplet size of 502.23 nm, polydispersity index of 0.170, and zeta potential of -32.26 mV. This emulsion was chemically and physically stable for 35 days at 30 ± 2 °C, showing potential as a food additive with biofunctional properties. The strategy here developed is an economical and environmentally friendly process that allows the reuse of the byproduct of B. gasipaes.

Effect of carotenoid pigments extracted from papaya epicarp (Carica papaya) on the characteristics of Frankfurt sausages

The industrialization of papaya generates a large amount of organic waste, which is rich in antioxidant compounds, especially carotenoids. The purpose of the present article was to study the influence of carotenoid pigments extracted from the papaya epicarp as a partial substitute for nitrites in Frankfurt sausages. Four concentrations of lipid extract of papaya epicarp were analyzed in said sausages. While the control sample had 0 % substitution, 25 %, 50 % and 75 % substitution of nitrite was added to the other samples. The sausages were kept at 6 ± 2 °C for 30 days. The chemical composition, pH, water holding capacity, water activity, emulsion stability, color coordinates, texture profile and sensory appearance were analyzed, and for the sausage that presented the best physicochemical parameters, the stability in the time at 0, 10, 20 and 30 days of storage. It was obtained that adding the papaya epicarp extract to a concentration of 25 % did not affect the physicochemical parameters. In addition, the texture and color characteristics, as well as the sensory evaluation showed the best results for said concentration, guaranteeing stability up to a period of 30 days of storage under vacuum packing conditions and under refrigeration (6 ± 2 °C). A new alternative is proposed to minimize the negative action of nitrites in analyzed Frankfurt sausages, replacing them with antioxidant compounds obtained from a raw material of vegetable origin.

La industrialización de la papaya genera residuos orgánicos, ricos en compuestos antioxidantes, especialmente, en carotenoides. El objetivo de la presente investigación fue estudiar la influencia de los pigmentos carotenoides extraídos de epicarpio de la papaya, como sustituto parcial de los nitritos en salchichas Frankfurt. En dichos embutidos, se analizaron cuatro concentraciones de extracto lipídico de epicarpio de papaya; mientras que la mezcla control tenía 0 % de sustitución, se añadió 25, 50 y 75 % de reemplazo de nitrito a las otras muestras. Las salchichas se mantuvieron a 6 ± 2 °C durante 30 días. Se analizó la composición química, el pH, la capacidad de retención de humedad, la actividad de agua, la estabilidad de la emulsión, las coordenadas de color, el perfil de textura y la apariencia sensorial y para el embutido que presentó los mejores parámetros fisicoquímicos, la estabilidad en el tiempo a 0, 10, 20 y 30 días de almacenamiento. Se obtuvo que la adición del extracto de epicarpio de papaya a una concentración del 25 % no afectó los parámetros fisicoquímicos. Además, las características de textura y color, así como la evaluación sensorial, mostraron los mejores resultados para dicha concentración, garantizando la estabilidad, hasta un periodo de 30 días de almacenamiento, en condiciones de envasado al vacío y en refrigeración (6 ± 2°C). Se propone una nueva alternativa para minimizar la acción negativa de los nitritos en las salchichas Frankfurt, sustituyéndolos por compuestos antioxidantes, obtenidos a partir de una materia prima de origen vegetal.

Introdução: A eletromiografia (EMG) tem sido utilizada para avaliar alterações no sistema mastigatório proporcionada pela disfunção temporomandibular (DTM). Objetivos: Verificar a confiabilidade teste-reteste de um protocolo de coleta do sinal EMG do músculo masseter em indivíduos com DTM. Métodos: Estudo transversal composto por 20 indivíduos com DTM. Os testes foram realizados em duas sessões com 7 dias de intervalo. O sinal EMG foi avaliado pelas variáveis integral (iEMG) e a raiz quadrada da média do sinal (RMS). Resultados: Na análise intradia a confiabilidade para o RMS (ICC2,k: 0.85 a 0.96 ) e iEMG ICC2,k: 0.85 a 0.95) foi excelente, enquanto que a confiabilidade teste/reteste foi pobre para ambas as variáveis RMS (ICC2,1: 0.03 a 0.29) e iEMG (ICC2,1: 0.08 a 0.39). Conclusões: O protocolo de coleta do sinal EMG do músculo masseter em indivíduos com DTM demonstrou que os dados são reprodutíveis somente na mesma sessão de coletas enquanto que, para coletas em dias alternados a confiabilidade foi pobre.

Introduction: Electromyography (EMG) has been used to assess alterations in the masticatory system caused by temporomandybular disorders (TMD). Objectives: The aim of this study was to verify the test-retest reliability of a protocol for recording the EMG signal from masseter muscle in TMD patients. Methods: This is a cross-sectional study comprising 20 individuals with TMD. Tests were performed in two sessions 7 days apart. The EMG signal was evaluated by the variables integral (iEMG) and the root mean square of the signal (RMS). Results: In the intraday analysis the reliability for the RMS (ICC2,k: 0.85 to 0.96) and iEMG (ICC2,k: 0.85 to 0.95) was excellent, while the test/retest reliability was poor for both RMS (ICC2,1: 0.03 to 0.29) and iEMG (ICC2,1: 0.08 to 0.39) variables. Conclusions: The protocol for collecting the EMG signal from the masseter muscle in an individual with TMD demonstrated that the data are reproducible only in the same recording session, whereas for c recording on alternate days, the reliability was poor.

AAV-mediated neuronal expression of an scFv antibody selective for Aß oligomers protects synapses and rescues memory in Alzheimer models.

The accumulation of soluble oligomers of the amyloid-ß peptide (AßOs) in the brain has been implicated in synapse failure and memory impairment in Alzheimer's disease. Here, we initially show that treatment with NUsc1, a single-chain variable-fragment antibody (scFv) that selectively targets a subpopulation of AßOs and shows minimal reactivity to Aß monomers and fibrils, prevents the inhibition of long-term potentiation in hippocampal slices and memory impairment induced by AßOs in mice. As a therapeutic approach for intracerebral antibody delivery, we developed an adeno-associated virus vector to drive neuronal expression of NUsc1 (AAV-NUsc1) within the brain. Transduction by AAV-NUsc1 induced NUsc1 expression and secretion in adult human brain slices and inhibited AßO binding to neurons and AßO-induced loss of dendritic spines in primary rat hippocampal cultures. Treatment of mice with AAV-NUsc1 prevented memory impairment induced by AßOs and, remarkably, reversed memory deficits in aged APPswe/PS1ΔE9 Alzheimer's disease model mice. These results support the feasibility of immunotherapy using viral vector-mediated gene delivery of NUsc1 or other AßO-specific single-chain antibodies as a potential therapeutic approach in Alzheimer's disease.

Abstract This study aimed to investigate the relationship between sexual maturation and anthropometric and blood pressure indicators in teenagers. This was a population-based cross-sectional study, conducted with 345 teenagers, aged 10 to 19 years, between 2018 and 2020. In this study, data referent to sociodemographic and anthropometric variables, blood pressure, and sexual maturation were collected. The data analysis was performed by applying the Principle Component Analysis (PCA), which generated three components and then tested the correlation between sexual maturation and the generated components. Most of the teenagers were female (53%), normotensive (66.1%), and with a normal weight (73%). A positive correlation was found between breast development and component 1 and component 2, as well as a negative correlation between the breasts and component 3. In the boys, the development of genitals and pubic hair was positively correlated with component 2 and inversely correlated with component 3. It could therefore be concluded that there is a relationship between sexual maturation and the anthropometric and blood pressure indicators, which proved to be representative variables for cardiovascular risk in teenagers, even if not in their entirety.

Effect of temperature and particle size on physicochemical and techno-functional properties of peach palm peel flour (Bactris gasipaes, red and yellow ecotypes).

In this study, the effect of temperature and particle size on the techno-functional properties of the flour from peach palm fruit peels (Bactris gasipaes, red and yellow ecotype) were evaluated. The flour from peach palm epicarp obtained by natural convective drying was physicochemically characterized, including the assessment of total dietary fiber determined under the gravimetric enzymatic method. The results obtained showed that temperature and particle size present a significant effect (p < 0.001) on techno-functional properties except for swelling capacity. The flour from the red ecotype presented better nutritional: total dietary fiber 47.93 ± 1.72%, protein 6.87 ± 0.15% and techno-functional properties: water retention capacity (WRC) 7.13 ± 0.29 g/g, oil retention capacity (ORC) 6.24 ± 0.08 g/g, emulsifier activity (EA) 56.84 ± 0.28%, emulsifier stability (ES) 50.33 ± 0.31% than the yellow one water absorption capacity (WAC) 5.31 ± 0.03 g/g and water solubility (WS) 59.58 ± 0.04% at 60 °C and 0.25 mm. Therefore, this study showed that the flour obtained from peach palm fruit peels contains high fiber and protein values and could be used as a promising natural additive (source of dietary fiber or emulsifier) for the food industry.

Effect of Adding Guava (Psidium guajava) Epicarp Extract Flour on the Physicochemical, Textural, Colour and Sensory Properties of Frankfurters.

RESEARCH BACKGROUND: The industrial transformation of tropical fruits, and in particular guava, generates a large quantity of by-products that are generally disposed of as organic waste. In these by-products a large quantity of bioactive substances is concentrated, such as carotenoids, which can be used for the partial substitution of nitrites in meat sausages without affecting their physicochemical, colour and conservation characteristics. Although there are some studies in this regard, there is still a lack of research, especially on guava residues, to verify this hypothesis. Therefore, the aim of this study is to investigate the influence of the components of the guava epicarp extract on the physicochemical, textural, colour and sensory properties of frankfurters. EXPERIMENTAL APPROACH: There treatments were investigated (25, 50 and 75% nitrite replacement with guava epicarp flour extract), along with a control treatment without the extract. The physicochemical properties, colour coordinates, and texture parameters were analysed, and a sensory evaluation was also carried out. The treatment that gave the best results was subjected to stability analysis over 30 days. RESULTS AND CONCLUSIONS: The addition of 25% guava epicarp flour extract gave the best results, since it did not affect the colouration of the sausages or their physicochemical and textural properties. Likewise, during the stability analysis over time, the parameters related to fat oxidation were not affected, and final products had a residual nitrite load of (23.6±0.2) mg/kg, lower than the maximum allowed (150 mg/kg). NOVELTY AND SCIENTIFIC CONTRIBUTION: The partial substitution of the nitrites in frankfurters with the carotenoids from the guava epicarp flour added in a mass fraction up to 25% can be a viable alternative to produce sausages with lower content of nitrites, without affecting their colouration or shelf life. This is important for the meat industry, which favours the development of new products using substances of natural origin.

Rapid size-exclusion high performance liquid chromatography method for the quality control of amyloid-ß oligomers.

Amyloid-ß (Aß) dysmetabolism is thought to be the main trigger for neurodegenerative events in Alzheimer's disease (AD). In particular, soluble Aß oligomers (AßOs) are proposed as key mediators of synaptic and cognitive dysfunction in AD. Over the past few decades, AßOs prepared from synthetic Aß have been widely applied in vitro and in vivo, the so-called chemical models of AD, uncovering their multiple neurotoxic mechanisms. However, the lack of a reliable quality control (QC) for synthetic AßOs may reflect poor experimental reproducibility. In keeping with this, we optimized and validated a rapid and reproducible SECHPLC method using fluorescence detection for the QC of synthetic AßOs.

Current pressure on the need to reduce nitrite content in meat products without affecting sensory properties such as color requires research for the development of healthy foods and the improvement of the quality of life of human beings. Fruit by-products are an important source of bioactive compounds, which can be used as natural additives in food processing. The objective of this study was to evaluate papaya epicarp flour as a natural ingredient in nitrite reduction of beef burger. Papaya epicarp samples after lyophilized were ground. A composite central design and a response surface methodology were used in order to analyze the process variables (nitrite and papaya epicarp flour concentrations) on the color of the beef burger. Response variables were carotenoid fractions and CIEL*a*b*. The optimal color-maximizing nitrite/flour ratio in beef burger was found corresponding to 150 mg/kg nitrite/40 mg/kg flour, where the maximum values for ß-cryptoxanthin, zeaxanthin, and lycopene were 0.451, 0.447, and 0.251 mg/100 g of sample, respectively, together with the lower value of L* (64.38). This study showed the agro-industrial potential of papaya epicarp flour to reduce nitrite concentrations in this food, in addition, the valuation of this by-product could bring economic and environmental benefits.
