High-Value Compounds in Papaya By-Products (Carica papaya L. var. Formosa and Aliança): Potential Sustainable Use and Exploitation.

BACKGROUND: Food waste is a global and growing problem that is gaining traction due to its environmental, ethical, social, and economic repercussions. Between 2022 and 2027, the worldwide papaya market is expected to have a huge increase, meaning a growth in organic waste, including peels and seeds. Thus, this study evaluated the potential use of peels and seeds of two mature papaya fruits as a source of bioactive compounds, converting these by-products into value-added products. Proximate analysis (AOAC methods), mineral content (ICP-MS), free sugars (HPLC-ELSD), fatty acid composition (GC-FID), vitamin E profile (HPLC-DAD-FLD), and antioxidant activity (DPPH and FRAP assays) were evaluated. RESULTS: Both by-products showed high total protein (20-27%), and dietary fiber (32-38%) contents. Papaya peels presented a high ash content (14-16%), indicating a potential application as a mineral source. 14 fatty acids were detected, with α-linolenic acid (30%) as the most abundant in the peels and oleic acid (74%) in the seeds. Both by-products showed high antioxidant activity. CONCLUSION: Papaya by-products display great potential for industrial recovery and application, such as formulation of new functional food ingredients.

A new and simple score to predict adequate and deep response to ursodeoxycholic acid in patients with primary biliary cholangitis: the ALP-A score.

BACKGROUND: Ursodeoxycholic acid (UDCA) is the standard treatment for primary biliary cholangitis (PBC), but a significant proportion of patients do not respond adequately, leading to increased risk of adverse outcomes. This study aims to develop a new and straightforward predictive score to identify PBC patients likely to achieve a complete response to UDCA. METHODS: A logistic regression analysis was conducted using a derivation cohort of PBC patients to identify pre-treatment variables associated with response to UDCA. This analysis led to the development of the ALP-A score, calculated as: Age at diagnosis divided by (alkaline phosphatase at diagnosis/upper limit of normal). ALP-A score accuracy was evaluated using the area under the ROC curve, validated with a large external cohort from Brazil. Additionally, the correlation between the ALP-A score and the previously validated UDCA response score (URS) was assessed. RESULTS: ALP-A score had good predictive power for adequate (AUC 0.794; 95% CI, 0.737-0.852) and deep (0.76; 95% CI, 0.69-0.83) UDCA response at 1 year of treatment. A cutoff score of 17 and 23 points was determined to be the optimal threshold for distinguishing adequate and deep responders, respectively, from non-responders. ALP-A score demonstrated a sensitivity of 73%, specificity of 71%, positive predictive value of 65%, negative predictive value of 78%, and overall accuracy of 72% for biochemical response. The URS displayed similar discriminative ability (AUC 0.798; 95% CI, 0.741-0.855). CONCLUSION: ALP-A score performs comparably to URS but offers the great advantage of simplicity for routine clinical use. It serves as a valuable tool to identify PBC patients less likely to respond to UDCA treatment, facilitating early consideration of alternative therapeutic approaches.

Algae Incorporation and Nutritional Improvement: The Case of a Whole-Wheat Pasta.

Algae contain high-quality proteins, dietary fiber, minerals, and phenolic compounds, making them promising alternative ingredients. Since pasta is consumed worldwide, it can be an effective vehicle for incorporating algae. This study compares the nutritional and antioxidant composition of whole-wheat pasta without and with enrichment of an algae mixture (containing Himanthalia elongata and Spirulina) and ascertains the influence of the cooking procedure on their features. Spirulina and H. elongata were also analyzed in parallel for comparison purposes. Macronutrients, chlorides and salt, total and free amino acid profiles, and antioxidant properties (total phenolic content and ferric reducing antioxidant power) were analyzed using AOAC, Mohr's, high performance liquid chromatography with fluorescence detection, and spectrophotometric methods, respectively. The results show a significant increase in fat (70.4%), protein (29.7%), ash (26.5%), and total amino acid (except for serine, tryptophan, isoleucine, and threonine) contents in the raw algae-enriched pasta. The antioxidant activity was also higher (4.15 versus 3.68 g ferrous sulfate eq./g dw, respectively). After cooking, protein, dietary fiber, total amino acids (except threonine) and antioxidant activity were stable in the algae-enriched pasta. Thus, algae can be an excellent ingredient for food applications with health benefits.

Bioactive Potential and Chemical Composition of Coffee By-Products: From Pulp to Silverskin.

Processing the coffee cherry into roasted beans generates a large amount of by-products, which can negatively impact the environment. The aim of this study was to analyze the bioactive potential and chemical composition of different coffee by-products (pulp, husk, parchment, silverskin, defective beans, and green coffee sieving residue) having in mind their bioactive potential for health and well-being. The coffee by-products showed a distinct nutritional composition. The content of ash, protein, fat, and total dietary fiber was significantly higher (p < 0.05) in coffee pulp (10.72% dw), silverskin (16.31% dw), defective beans (8.47% dw), and parchment (94.19% dw), respectively. Defective beans and the sieve residue exhibited a higher content of total phenolics (6.54 and 5.11 g chlorogenic acid eq./100 g dw, respectively) as well as higher DPPH• scavenging activity (3.11 and 2.85 g Trolox eq./100 g, respectively) and ferric-reducing antioxidant power (17.68 and 17.56 g ferrous sulfate eq./100 g dw, respectively). All the coffee by-products considered in this study are sources of caffeine and chlorogenic acids, in particular 5-caffeoylquinic acid (5.36-3787.58 mg/100 g dw, for parchment and defective beans, respectively). Thus, they can be recycled as functional ingredients for food, cosmetic and/or pharmaceutical industries, contributing to the social, economic, and environmental sustainability of the coffee industry.

Risk factors for cancer in patients with primary biliary cholangitis and autoimmune hepatitis and primary biliary cholangitis overlap syndrome.

INTRODUCTION AND OBJECTIVES: Primary biliary cholangitis (PBC) and autoimmune hepatitis (AIH) and PBC overlap syndrome (AIH/PBC) have been associated with a higher risk of hepatocellular carcinoma (HCC) and extra-hepatic malignancy (EHM). This study aims to assess potential risk factors associated with cancer development in PBC and AIH/PBC. MATERIALS AND METHODS: The Brazilian Cholestasis Study Group database was reviewed to compare clinical and laboratory features of PBC patients with HCC and EHM with those without cancer. RESULTS: Among the 752 PBC patients enrolled, 64 of them with AIH/PBC, 87 cancers were identified in 72 patients, including 20 cases of HCC and 67 of EHM. Patients with HCC had a higher prevalence of cirrhosis (95% vs. 32.5% of those subjects without cancer, p≤0.001), smoking (55% vs. 12.3%, p≤0.001), CREST syndrome (30% vs 7.6%, p=0.003) and prior azathioprine (30% vs 8%, p= 0.005) and prednisone (35% vs 14%, p= 0.018) use, whereas patients with EHM had a higher prevalence of smoking (42.3% vs 12.4% of those subjects without cancer, p= <0.001), AMA positivity (96.6% vs 80.1%, p≤0.001), azathioprine therapy (21% vs 7.9%, p= 0.01) and concurrent other autoimmune diseases. In multivariate analysis, cirrhosis, obesity and prior azathioprine therapy were independent risk factors for HCC, while Sjogren syndrome and psoriasis were associated with EHM. Fibrates reduced EHM risk. CONCLUSIONS: The prevalence of EHM is higher when compared to HCC in PBC patients. Cirrhosis, obesity, prior azathioprine use, and concurrent autoimmune diseases were significantly associated with cancer in PBC.

Brazilian berry waste as a source of bioactive compounds: grumixama (Eugenia brasiliensis Lam.) as a case study.

Grumixama, Eugenia brasiliensis Lam., is a Brazilian berry little explored commercially and scientifically. However, local small producers market this fruit in the form of frozen pulp, which generates bioresidues, composed of seeds and peels. With the view to propose strategies for valuing grumixama, this study aimed to determine the chemical composition and assess the bioactivities of the hydroethanolic extracts of the whole residue (GR), seed (GS) and peel (GP) fractions of E. brasiliensis. From the results, GP had the highest concentration of organic acids (oxalic, malic, ascorbic and citric acids), total tocopherols, condensed tannins, anthocyanins, and other flavonoids. On the other hand, GS showed the highest content of monounsaturated fatty acids and hydrolysable tannins, whereas GR displayed a mixture of compounds detected in each of its parts. Regarding the bioactivities, low extract concentrations were required in two in vitro antioxidant assays, namely TBARS (EC50 = 0.90-1.34 µg mL-1) and OxHLIA (IC50 = 21-65 µg mL-1). Furthermore, GP had the highest inhibition activity of cellular oxidation in the CAA assay (80 ± 0.6%), while GS showed the highest anti-inflammatory activity via nitric oxide production inhibition (EC50 = 98.0 ± 0.5 µg mL-1). All samples induced cell growth inhibition of the tested tumor cells (GI50 = 14.7-186 µg mL-1) besides antibacterial and antifungal effects at low concentrations, but all samples were harmful to normal cells at moderate concentrations (GI50 = 145-268 µg mL-1). Therefore, E. brasiliensis residue could be a good source of bioactive compounds to be used in several areas. However, additional studies are needed to confirm its safety as well as to unravel the mechanisms behind its biological activities.

Insights into the Chemical Composition and In Vitro Bioactive Properties of Mangosteen (Garcinia mangostana L.) Pericarp.

The industrial processing of mangosteen (Garcinia mangostana L.) generates high amounts of waste, as ~60% of the fruit is formed by an inedible pericarp. However, its pericarp has been explored as a source of xanthones; nevertheless, studies addressing the recovery of other chemical compounds from such biomass are still scarce. Hence, this study intended to elucidate the chemical composition of the mangosteen pericarp, including fat-soluble (tocopherols and fatty acids) and water-soluble (organic acids and phenolic compound non-xanthones) compounds present in the following extracts: hydroethanolic (MT80), ethanolic (MTE), and aqueous (MTW). In addition, the antioxidant, anti-inflammatory, antiproliferative and antibacterial potentials of the extracts were assessed. The mangosteen pericarp showed a composition with seven organic acids, three tocopherol isomers, four fatty acids and fifteen phenolic compounds. Regarding the extraction of phenolics, the MT80 was the most efficient (54 mg/g extract), followed by MTE (19.79 mg/g extract) and MTW (4.011 mg/g extract). All extracts showed antioxidant and antibacterial activities; however, MT80 and MTE extracts were more efficient than MTW. Only MTW did not show anti-inflammatory properties, whereas MTE and MT80 showed inhibitory activities towards tumor cell lines. Notwithstanding, MTE showed cytotoxicity towards normal cells. Our findings support the idea that the ripe mangosteen pericarp is a source of bioactive compounds, although their recovery is dependent on the extraction solvent.

Effect of Different Time/Temperature Binomials on the Chemical Features, Antioxidant Activity, and Natural Microbial Load of Olive Pomace Paste.

Olive pomace is a by-product from olive oil production that can be further processed to obtain olive pomace paste. In this work, the influence of different time/temperature binomials (65 °C/30 min; 77 °C/1 min; 88 °C/15 s; and 120 °C/20 min) on the nutritional quality, chemical composition, and efficiency on control/elimination of natural microbial load of olive pomace paste was ascertained. The treatments significantly impacted the contents of ash, fat, vitamin E, phenolics (including hydroxytyrosol), flavonoids, and antioxidant activity, but not the fatty acids profile. The binomial 88 °C/15 s showed the greatest potential since it better preserved the phytochemical and antioxidant properties as well as the protein and fiber contents. This binomial is also faster and easy to be implemented at an industrial level, allowing the obtention of a safe functional ingredient to satisfy consumers' demands for novel sustainable products, simultaneously, responding to food safety and food security concerns.

Updated Organic Composition and Potential Therapeutic Properties of Different Varieties of Olive Leaves from Olea europaea.

Olea europaea L. folium merits further exploration of the potential of its substrates for therapeutic supplements. Quantitative and qualitative analyses were conducted on samples of Madural, Verdeal, and Cobrançosa elementary leaves and leaf sprouts (mamões) collected in the region of Valpaços, Portugal. Organic analysis assessed the moisture content, total carbohydrates, ash, protein, and fat contents, total phenolic content (TPC), vitamin E, and fatty acid (FA) profiles. Moisture content was determined through infrared hygrometry and TPC was determined by a spectrophotometric method. Concerning organic analysis, all leaf samples showed similar moisture content, though Cobrançosa's leaf sprouts and Verdeal's elementary leaves had slightly lower contents. Meanwhile, these cultivars also showed a higher TPC, α-tocopherol isomer, and fatty acid composition (FAC). FAC in all samples exhibited higher contents of PUFA and SFA than MUFA, with a predominance of linolenic and palmitic acids. Organic analyses of Cobrançosa's leaf sprouts and Verdeal's elementary leaf extracts allow for the prediction of adequate physiological properties regarding neuroinflammatory, neurobehavioral, metabolic, cardiovascular, osteo-degenerative, anti-ageing, pulmonary, and immunological defense disorders. These physiological changes observed in our preliminary in silico studies suggest an excellent nutraceutical, which should be borne in mind during severe pandemic situations.

Effect of the Case for Carpule as a Visual Passive Distraction Tool on Dental Fear and Anxiety: A Pilot Study.

The present cross-over study aimed to evaluate the effect of a visual passive distraction tool, a case for carpule, in the management of fear and anxiety during invasive dental treatment. Children between the ages of 4 and 8 years that need at least two treatments with inferior alveolar nerve block were selected. All the included children received two treatments at different moments: in one treatment, local anesthesia was performed with a visual passive distraction tool, the crocodile case, for carpule (experimental); in the other treatment, local anesthesia was performed without the device (control). An evaluation of the anxiety levels was performed by measuring the heart rate and salivary cortisol levels. Wilcoxon's nonparametric test was used for a data analysis (p < 0.05). The mean heart rate with the visual passive distraction device fell from 81.8 to 78.1, while the control rose from 91.4 to 100 (p < 0.05). The mean salivary cortisol levels with the visual passive distraction device fell from 2.0 to 1.6, while in the control, they rose from 2.1 to 2.4 (p < 0.05). In conclusion, the crocodile case for carpule as a visual passive distraction device contributed positively to the management of fear and anxiety during inferior alveolar nerve block in children.

Characterization of Chia Seeds, Cold-Pressed Oil, and Defatted Cake: An Ancient Grain for Modern Food Production.

The increasing demand for superfoods has resulted in an increase in chia seeds consumption. The reintroduction of this ancient crop in agriculture is useful to ensure food security since it can grow in high-stress conditions. The current study aimed to characterize chia seeds, cold-pressed oil, and defatted cake (the oil extraction by-product) to improve their value and to meet consumer's expectations (low-fat products). Chia seeds presented a significantly higher energy value than cake (444 vs. 284 kcal/100 g, respectively) due to fat removal (33 vs. 7%). The cake showed higher contents of total minerals (6 vs. 5%), protein (27 vs. 18%), and fiber (48 vs. 38%) in comparison to the seeds, and was hence considered a promising food ingredient. The major fatty acid in oil, seeds, and cake was α-linolenic acid (62-66%), and the vitamin E content was 409, 200, and 44 mg/kg, respectively. The major amino acid in the seeds and cake was glutamic acid (49 vs. 36 mg/g). The oil had a low oxidative stability (1 h), and the total phenolics content was 1.3 mg gallic acid equivalents/100 g. Chia cake incorporation in food formulations will follow consumer's interests, and the obtained oil can be used to improve the oil supply for different applications. This approach adds value to the concept of "one health" since it includes the culture, the environment, and the consumers.

Response to Ursodeoxycholic Acid May Be Assessed Earlier to Allow Second-Line Therapy in Patients with Unresponsive Primary Biliary Cholangitis.

BACKGROUND: Response to ursodeoxycholic acid (UDCA) in primary biliary cholangitis (PBC) has been traditionally assessed 1 to 2 years after treatment initiation. With the development of new drugs, some patients may benefit from an earlier introduction of second-line therapies. AIMS: This study aims to identify whether well-validated response criteria could correctly identify individuals likely to benefit from add-on second-line therapy at 6 months. METHODS: Analysis of a multicenter retrospective cohort which included only patients with clear-cut PBC. RESULTS: 206 patients with PBC (96.6% women; mean age 54 ± 12 years) were included. Kappa concordance was substantial for Toronto (0.67), Rotterdam (0.65), Paris 1 (0.63) and 2 (0.63) criteria at 6 and 12 months, whereas Barcelona (0.47) and POISE trial (0.59) criteria exhibited moderate agreement. Non-response rates to UDCA was not statistically different when assessed either at 6 or 12 months using Toronto, Rotterdam or Paris 2 criteria. Those differences were even smaller or absent in those subjects with advanced PBC. Mean baseline alkaline phosphatase was 2.73 ± 1.95 times the upper limit of normal (× ULN) among responders versus 5.05 ± 3.08 × ULN in non-responders (p < 0.001). CONCLUSIONS: After 6 months of treatment with UDCA, the absence of response by different criteria could properly identify patients who could benefit from early addition of second-line therapies, especially in patients with advanced disease or high baseline liver enzymes levels.

Social skills training with a tabletop role-playing game, before and during the pandemic of 2020: in-person and online group sessions.

Background: The area of social skills is broad, in theory and in practice. For social skills training, various clinical practices have been applied in group sessions, as have motivational resources such as role-playing games (RPGs). In recent years, the need arose to assess the clinical impact of the pandemic. The objective of this study was to determine the impact that the pandemic has had on in-person and online social skills training. Methods: We evaluated six subjects with autism spectrum disorder, with or without another, similar disorder, each of whom attended a total of 12 two-hour RPG sessions over a 12-month period. The original (Portuguese-language) version of the Social Skills Inventory for Adolescents was applied at three different time points (pre-, mid-, and post-intervention). Results: After six in-person tabletop RPG sessions, there was an increase in the mean frequency scores and a decrease in the mean difficulty scores. However, during the pandemic, the remaining six sessions were conducted online and the effect was the opposite. Conclusion: Our data indicate that there is a need for further studies assessing social skills training in online contexts.

Efeito da germinação e da desidratação no valor nutritivo, compostos bioativos e atividade antioxidante de farinhas de leguminosas / Germination and dehydration effects on nutritional value, bioactive compounds and antioxidant activity of legume flours / Efectos de la germinación y la deshidratación sobre el valor nutritivo, los compuestos bioactivos y la actividad antioxidante de harinas de leguminosas

Os objetivos deste trabalho foram avaliar o efeito da germinação no teor de macronutrientes e da desidratação em compostos bioativos, nutrientes e atividade antioxidante de farinhas das leguminosas Phaseolus lunatus L. e Cajanus cajan (L. Millsp.) germinadas. As condições de germinação foram controladas em laboratório e as amostras foram submetidas à desidratação térmica (55°C) e liofilização. Foram realizadas as análises de composição centesimal, fenólicos totais flavonoides, atividade antioxidante (DPPH, FRAP), perfil de ácidos graxos (CG-FID) e de vitâmeros de tocoferol (HPLC- DAD). A germinação das leguminosas promoveu aumento de proteínas, lipídios e carboidratos. O processamento térmico para desidratação contribuiu para perdas de proteínas, lipídios, cinzas, e maior atividade antioxidantes em ambas as espécies. O perfil de ácidos graxos e vitâmeros de tocoferol mostraram-se com variações que dependem do tipo de leguminosa e condições de processamento, podendo ser positivas ou negativas. Farinhas de leguminosas germinadas pode ser uma alternativa para a inserção na dieta ou em formulações alimentícias e as condições de processamento devem ser monitoradas com intuito de otimiza propriedades nutritivas e funcionais.

The objectives of this work were to evaluate the effect of germination on macronutrient content and dehydration on bioactive compounds, nutrients and antioxidant activity of flours from germinated Phaseolus lunatus L. and Cajanus cajan (L. Millsp.) legumes. The germination conditions were controlled in the laboratory and the samples were submitted to thermal dehydration (55°C) and lyophilization. Analyses were carried out for centesimal composition, total phenolic flavonoids, antioxidant activity (DPPH, FRAP), fatty acid profile (GC-FID) and tocopherol vitamers (HPLC-DAD). Germination of the legumes promoted an increase in proteins, lipids and carbohydrates. Thermal processing for dehydration contributed to losses of proteins, lipids, ash, and higher antioxidant activity in both species. The profile of fatty acids and tocopherol vitamers showed variations that depend on the type of legume and processing conditions, and can be positive or negative. Sprouted legume flours can be an alternative for insertion in the diet or in food formulations and the processing conditions must be monitored in order to optimize nutritional and functional properties.

Los objetivos de este trabajo fueron evaluar el efecto de la germinación sobre el contenido en macronutrientes y de la deshidratación sobre los compuestos bioactivos, los nutrientes y la actividad antioxidante de harinas de leguminosas germinadas de Phaseolus lunatus L. y Cajanus cajan (L. Millsp.). Las condiciones de germinación se controlaron en el laboratorio y las muestras se sometieron a deshidratación térmica (55°C) y liofilización. Se realizaron análisis de composición centesimal, flavonoides fenólicos totales, actividad antioxidante (DPPH, FRAP), perfil de ácidos grasos (GC-FID) y vitaminas tocoferol (HPLC-DAD). La germinación de las leguminosas promovió un aumento de proteínas, lípidos y carbohidratos. El procesado térmico para la deshidratación contribuyó a pérdidas de proteínas, lípidos, cenizas y a una mayor actividad antioxidante en ambas especies. El perfil de ácidos grasos y vitaminas tocoferol mostró variaciones que dependen del tipo de legumbre y de las condiciones de procesado, pudiendo ser positivas o negativas. Las harinas de leguminosas germinadas pueden ser una alternativa para su inserción en la dieta o en formulaciones alimentarias y las condiciones de procesado deben ser monitorizadas para optimizar las propiedades nutricionales y funcionales.

Green/Roasted Coffee and Silverskin Extracts Inhibit Sugar Absorption by Human Intestinal Epithelial (Caco-2) Cells by Decreasing GLUT2 Gene Expression.

Moderate coffee ingestion has been associated with a decrease in type 2 diabetes risk, mainly due to its richness in chlorogenic acids (CGA). To explore this, extracts of green beans, roasted beans, and silverskin were prepared by aqueous ultrasound-assisted extraction and characterized by a reversed-phase high-performance liquid chromatography-photodiode array detector (RP-HPLC-DAD). The effects on the uptake of glucose and fructose by human intestinal epithelial (Caco-2) cells and the influence on the expression of sugar transporter genes (by RT-qPCR) were investigated and compared. The uptake of 3H-deoxy-D-glucose and 14C-fructose by Caco-2 cells was significantly reduced by all the extracts, with green coffee (which also contained higher amounts of CGA) achieving the highest efficiency. Although silverskin presented the lowest amounts of CGA and caffeine, it promoted an inhibitory effect similar to the effects of green/roasted beans. In the case of glucose uptake, the effect was even higher than for roasted coffee. This activity is explained by the ability of the extracts to markedly decrease GLUT2, but not GLUT5 gene expression. In addition, a decrease in SGLT1 gene expression was also found for all extracts, although not at a statistically significant rate for silverskin. This study also revealed a synergistic inhibitory effect of caffeine and 5-CQA on the uptake of sugars. Thus, silverskin appears as an interesting alternative to coffee, since the valorization of this by-product also contributes to the sustainability of the coffee chain.

Influence of Single-Nucleotide Polymorphisms on Vitamin D Receptor Expression in Periodontal Ligament Fibroblasts as a Response to Orthodontic Compression.

This study aimed to evaluate if single-nucleotide polymorphisms (SNPs) in the vitamin D receptor (VDR) gene are associated with gene expression in human periodontal ligament (hPDL) fibroblasts under simulated orthodontic compressive force. hPDL samples from 57 patients were used. A physiological compressive strain was performed to simulate orthodontic tooth movement in pressure areas under cell culture conditions. The RNA from hPDL fibroblasts was isolated to determine the relative gene expression (mRNA) of the VDR. The DNA was also isolated for the genotyping analysis of five SNPs in the VDR gene: BglI (rs739837, G/T), BsmI (rs1544410, T/C), ApaI (rs7975232, A/C), FokI (rs2228570, A/G), and TaqI (rs731236, A/G). Real-time polymerase chain reaction was used for both analyses. Kruskal−Wallis tests were used to compare VDR expression among genotypes of each SNP. A linear regression analysis was performed to evaluate SNP−SNP interaction. An established alpha of 5% was used. The relative mRNA VDR expression according to the genotypes in the SNPs BglI, BsmI, ApaI, FokI, and TaqI was not statistically significantly different (p > 0.05). The SNP−SNP interaction evaluated by regression analysis did not demonstrate any statistically significant association. No association was observed (p > 0.05). In conclusion, the SNPs BglI (rs739837), BsmI (rs1544410), ApaI (rs7975232), FokI (rs2228570), and TaqI (rs731236) did not show an impact on VDR gene expression in hPDL fibroblasts under simulated orthodontic compressive force.

Nutritional and Chemical Characterization of Poppy Seeds, Cold-Pressed Oil, and Cake: Poppy Cake as a High-Fibre and High-Protein Ingredient for Novel Food Production.

Currently, society demands natural healthy foods with improved nutritional characteristics. Accordingly, poppies (Papaver somniferum) are a traditional crop, cultivated for food and pharmaceutical purposes, whose seeds meet consumers' preferences, making them a promising candidate for incorporation into the formulation of novel functional foods. This work performed an overall chemical characterization of poppy seeds, cold-pressed oil, and press cake, a by-product of the oil industry. The proximate composition, fatty acids, and vitamin E profiles of the oil fraction were analysed with respect to the whole seeds and the cake. The cold-press oil extracted from the poppy seeds was also characterized. Since poppy cake is a partially defatted product, it has a lower fat content than the seeds, but higher content of the rest of its elements, namely, ash (10%), protein (26%), and fibre (38%). Regarding protein composition, the major amino acid in the cake and seeds was determined to be glutamic acid (59 and 36 mg/g, respectively). All the samples presented α- and γ-tocopherols (>21 and >25 mg/kg, respectively) and the fatty acids profile of the oil fraction was mainly composed of unsaturated fatty acids, where linoleic acid predominates (>50%). The oil's oxidative stability was low (2.8 h), according to the predominance of unsaturated fatty acids. Thus, poppy cake may be considered as an ingredient with great potential for incorporation into products in the food industry according to its high content in protein and fibre, and the remaining fat content, where polyunsaturated fatty acids predominate.

Potential Therapeutic Properties of the Leaf of Cydonia Oblonga Mill. Based on Mineral and Organic Profiles.

Leaf extract of Cydonia Oblonga Mill. is interesting for further exploration of the potential of its substrates for therapeutic supplements. Quantitative and qualitative analyses were conducted on samples of green (October), yellow (November), and brown (December) quince leaves collected in the region of Pinhel, Portugal. Mineral analysis determined the measurements of the levels of several macro- and micro-elements. Organic analysis assessed the moisture content, total phenolic content (TPC), vitamin E, and fatty acid (FA) profiles. Mineral analysis was based on ICP-MS techniques, while the profiles of vitamin E and FA relied on HPLC-DAD-FLD and GC-FID techniques, respectively. Moisture content was determined through infrared hygrometry and TPC was determined by spectrophotometric methods. Regarding the mineral content, calcium, magnesium, and iron were the most abundant minerals. Concerning organic analysis, all leaf samples showed similar moisture content, while the TPC of gallic acid equivalents (GAE) and total vitamin E content, the most predominant of which was the α-tocopherol isomer, showed significant variations between green-brown and yellow leaves. FA composition in all leaf samples exhibited higher contents of SFA and PUFA than MUFA, with a predominance of palmitic and linolenic acids. Organic and inorganic analysis of quince leaves allow for the prediction of adequate physiological properties, mainly cardiovascular, pulmonary, and immunological defenses, which with our preliminary in silico studies suggest an excellent supplement to complementary therapy, including drastic pandemic situations.

Possible repercussions of the COVID-19 pandemic on women with fibromyalgia: longitudinal study / Possíveis repercussões da pandemia da COVID-19 em mulheres com fibromialgia: estudo longitudinal

ABSTRACT BACKGROUND AND OBJECTIVES: In the context of the pandemic caused by COVID-19, individuals with chronic pain, as in fibromyalgia, experienced the impact of social isolation. Tus, considering the scarcity of studies that contemplate initial assessments of women with fibromyalgia before the pandemic period and that compare them with the pandemic context moment, the objective was to analyze the possible repercussions of the pandemic resulting from COVID-19 on the psychological symptoms, quality of life and pain. METHODS: A descriptive, cross-sectional, observational research with an exploratory and quantitative approach. Te sample was composed of 15 women with fibromyalgia for at least three months, aged between 43 and 55 years and with pain level above four on the Visual Analog Scale (VAS). Te Sociodemographic and Clinical Questionnaire, the Beck Anxiety Inventory (BAI), the Beck Depression Inventory (BDI), and the Health Assessment Questionnaire (HAQ) were used. RESULTS: On average, pain intensity during social isolation (8,40±1,50) and anxiety level (29,80±13,97) were higher than before the pandemic (6,06±1,62, p=0,001) and (22,33±9,69, p=0,006), respectively. In other words, the participants showed higher levels of anxiety and pain during the period of social isolation. Mean depressive symptoms and quality of life difered minimally, showing no statistical significance, with p=0.94 and p=0.46, respectively. CONCLUSION: The COVID-19 pandemic may have contributed to the increase in pain and anxiety levels during the pandemic period. However, other uncontrolled variables may have infuenced this result, such as resilience and family support, for example.

RESUMO JUSTIFICATIVA E OBJETIVOS: Diante do contexto da pandemia ocasionada pela COVID-19, os indivíduos com dor crônica, como na fibromialgia, experimentaram o impacto do isolamento social. Assim, considerando a escassez de estudos que contemplem avaliações iniciais de mulheres com fibromialgia antes do período de pandemia e que as comparem com o momento de contexto pandêmico, objetivou-se analisar as possíveis repercussões da pandemia decorrentes da COVID-19 em sintomas psicológicos, qualidade de vida e dor. MÉTODOS: Trata-se de uma pesquisa observacional descritiva, longitudinal, com abordagem exploratória e quantitativa. A amostra foi composta por 15 mulheres com fibromialgia a pelo menos três meses, com idades entre 43 e 55 anos e com nível de dor acima de quatro na Escala Analógica Visual (EAV). Foram utilizados o Questionário Sociodemográfico e Clínico, o Inventário Beck de Ansiedade (IBA), o Inventário Beck de Depressão (IBD) e o Health Assessment Questionnaire (HAQ). RESULTADOS: Em média, a intensidade da dor durante o isolamento social (8,40±1,50) e o nível de ansiedade (29,80±13,97) foram maiores do que antes da pandemia (6,06±1,62, p=0,001) e (22,33±9,69, p=0,006), respectivamente. Ou seja, as participantes mostraram maiores níveis de ansiedade e dor durante o período de isolamento social. A média dos sintomas depressivos e qualidade de vida diferiram minimamente, não demostrando significância estatística, com p=0,94 e p=0,46, respectivamente. CONCLUSÃO: A pandemia da COVID-19 pode ter contribuído para o aumento das queixas de dor e ansiedade durante o período pandêmico. Entretanto, outras variáveis não controladas podem ter infuenciado nesse resultado, como resiliência e suporte familiar, por exemplo.

Agri-Food Surplus, Waste and Loss as Sustainable Biobased Ingredients: A Review.

Ensuring a sustainable supply of food for the world's fast growing population is a major challenge in today's economy, as modern lifestyle and increasing consumer concern with maintaining a balanced and nutritious diet is an important challenge for the agricultural sector worldwide. This market niche for healthier products, especially fruits and vegetables, has increased their production, consequently resulting in increased amounts of agri-food surplus, waste, and loss (SWL) generated during crop production, transportation, storage, and processing. Although many of these materials are not utilized, negatively affecting the environmental, economic, and social segments, they are a rich source of valuable compounds that could be used for different purposes, thus preventing the losses of natural resources and boosting a circular economy. This review aimed to give insights on the efficient management of agri-food SWL, considering conventional and emerging recovery and reuse techniques. Particularly, we explored and summarized the chemical composition of three worldwide cultivated and consumed vegetables (carrots, broccoli and lettuce) and evaluate the potential of their residues as a sustainable alternative for extracting value-added ingredients for the development of new biodynamic products.
