RESUMO

Cocoa beans (Theobroma cacao L.) can be used for craft chocolate production, which arouses consumer interest due to their perceived better quality. This study aimed to evaluate the chemical profile of 80% artisanal chocolate samples produced with cocoa beans subjected to different maturation conditions. In the first maturation process, beans were matured under no-oxygen conditions, and in the second, the toasted beans were matured in oak barrels. The volatile compounds of the chocolate samples were extracted by the solid-phase microextraction method in headspace mode and analyzed by gas chromatography/mass spectrometer. The non-volatile compounds were extracted with methanol and analyzed through paper spray mass spectrometry. Overall, 35 volatile compounds belonging to different chemical classes (acids, alcohols, aldehydes, ketones, esters, and pyrazines) were identified, such as propanoic acid and butane-2,3-diol. In addition, 37 non-volatile compounds, such as procyanidin A pentoside and soyasaponin B, were listed. Tannins, flavonoids, and phenylpropanoids were the main chemical classes observed, varying between the two samples analyzed. Therefore, it was possible to verify that maturation conditions affected the metabolomic profile of the 80% artisanal chocolate samples, being able to influence the sensory characteristics and bioactive compounds profile. Given these results, the sensory evaluation of these chocolates is suggested as the next step.

RESUMO

OBJETIVO: Compreender a percepção masculina sobre sua própria participação durante a gestação. MÉTODO: Pesquisa descritiva de abordagem qualitativa. As informações foram coletadas por meio de entrevistas semiestruturadas com dez homens acompanhantes de puérperas em Alojamento Conjunto, e submetidas a análise temática. RESULTADOS: De maneira geral, a participação do homem no pré-natal ocorreu no acompanhamento nas consultas, em exames e no suporte na realização das tarefas domésticas. Algumas limitações foram a rotina de trabalho e aspectos jurídicos relacionados a questões trabalhistas. Os entrevistados apontaram sugestões para maior incentivo na sua participação e na inclusão na vivência da gestação e do pré-natal. CONCLUSÃO: Os profissionais da área devem dar voz aos pais, e devem inseri-los como alvo das ações em saúde, tornando-o também protagonista neste momento, e assim reforçando as boas práticas assistenciais determinadas por políticas governamentais.


OBJECTIVE: To understand men's experiences and perceptions of their involvement in pregnancy. METHOD: A descriptive, qualitative research approach was used. Information was collected through semi-structured interviews with ten male partners of postpartum women in a shared accommodation setting and subjected to thematic analysis. RESULTS: Overall, men's involvement in prenatal care included attending medical appointments, being present during examinations, and assisting with household tasks. Some limitations included work routines and legal aspects related to work issues. Respondents suggested ways to encourage greater involvement and inclusion in the experience of pregnancy and prenatal care. CONCLUSION: Health professionals should give fathers a voice and include them as targets of health initiatives, making them active participants during this period and reinforcing good health practices set by government policies.

RESUMO

The authors present a striking case of a patient experiencing a lichenoid drug eruption secondary to immunotherapy, curiously sparing scarred skin from past burns. We observed vastly higher amounts of inflammatory lymphoid cells staining for PD-1; 70% in skin with a lichenoid drug reaction and 50% in scarred skin. The lack of a lichenoid reaction at sites of scarred skin may indicate that a basement membrane component may be causative for a lichenoid drug eruption.

RESUMO

The chemical composition of propolis varies between different types, due to the specific vegetation found near the hives and the climatic and soil conditions worldwide. Green propolis is exclusive to Brazil, produced by bees, with the resin of the plant Baccharis dracunculifolia. Brown propolis is a specific variety produced mainly in Northeast Brazil from the plant Hyptis divaricata, also known as "maria miraculosa". Dark propolis is a variety of propolis produced by bees from the resin of the plant known as Jurema Preta (Mimosa hostilis benth). In this study, the aqueous extracts of green, brown, and dark propolis were analyzed for their antioxidant capacity using ABTS, FRAP, and DPPH, and their chemical profiles were determined using paper spray mass spectrometry. Among the three extracts, green propolis had the highest content of total phenolic compounds (2741.71 ± 49.53 mg GAE. 100 g-1), followed by brown propolis (1191.55 ± 36.79 mg GAE. 100 g-1), and dark propolis had the lowest content (901.79 ± 27.80 mg GAE. 100 g-1). The three types of propolis showed high antioxidant capacity, with green showing the highest antioxidant capacity for the three methods used. Using paper spray mass spectrometry, it was possible to suggest the presence of 116 substances, including flavonoids (56), phenylpropanoids (30), terpenes (25), carboxylic acids (1), benzoic acid derivatives (1), fatty acids (1), amino acids (1) and alkaloids (1). The compounds in the green, brown, and dark propolis extracts reinforce the bioactive potential for application in these tree extracts' food and pharmaceutical products.

RESUMO

BACKGROUND: Previous functional magnetic resonance imaging studies have identified brain-connectivity alterations across multiple regions in people with migraine when compared to healthy controls. Few studies have focused on such changes throughout the different phases of the migraine cycle. We aimed to investigate functional connectivity during spontaneous occurring episodic migraine attacks, in comparison to interictal periods. METHODS: Eleven women with episodic migraine without aura underwent two sessions of resting-state fMRI, during and outside of a spontaneous migraine attack. Functional connectivity changes were assessed across canonical resting-state networks, identified by independent component analysis. Significantly altered connectivity was correlated with migraine attack symptoms. RESULTS: Decreased functional connectivity between subregions of the sensorimotor network (specifically, the primary somatosensory and motor cortices) and the posterior insula, bilaterally, was found during attacks. In both sessions, the functional connectivity between these regions was lower in patients who usually suffered longer attacks. DISCUSSION: The sensorimotor and insular regions are involved in nociceptive, autonomic, and somatosensory processing so the finding of reduced connectivity between these structures within a migraine attack is likely associated to the perception of pain and the heighten sensitivity to stimuli experienced in this disorder.

RESUMO

Diverse drugs have been used for the management of inflammation disorders and pain. However, they present many side effects and stimulate the search for new pharmacotherapeutic alternatives. Plant-derived products such as copaiba essential oil (CO) offer beneficial pharmacological effects. On the other hand, essential oil's low water solubility and physical instability hinder its in vivo application. Thus, poly-ɛ-caprolactone (PCL)-based nanocarriers have been used to increase their stability and efficacy. This work aimed to encapsulate CO in PCL nanocapsules and evaluate their effect on inflammation models and pain. The polymeric nanocapsules loading CO (CO-NC) were prepared by nanoprecipitation technique, characterized, and analyzed for their anti-inflammatory effect in vitro and in vivo. The results showed that CO-NC presented a spherical shape, 229.3 ± 1.5 nm diameter, and a negative zeta potential (approximately -23 mV). CO and CO-NC presented anti-inflammatory and antioxidant effects by LPS-activated macrophages (J774 cells). In addition, CO-NC significantly reduced TNF-α secretion (3-fold) compared to CO. In vivo, pre-treatment with CO or CO-NC (50, 100, 200 mg/kg, intraperitoneal; i.p) reduced the mechanical allodynia, paw edema, and pro-inflammatory cytokines induced by intraplantar (i.pl) injection of carrageenan in mice. Specifically, CO-NC (200 mg/kg; i.p.) reduced the production of TNF-α similar to the control group. Our results support using polymeric nanocapsules for CO delivery in inflammatory conditions.

RESUMO

Object recognition memory (ORM) allows identification of previously encountered items and is therefore crucial for remembering episodic information. In rodents, reactivation during recall in the presence of a novel object destabilizes ORM and initiates a Zif268 and protein synthesis-dependent reconsolidation process in the hippocampus that links the memory of this object to the reactivated recognition trace. Hippocampal NMDA receptors (NMDARs) modulate Zif268 expression and protein synthesis and regulate memory stability but their possible involvement in the ORM destabilization/reconsolidation cycle has yet to be analyzed in detail. We found that, in adult male Wistar rats, intra dorsal-CA1 administration of the non-subunit selective NMDAR antagonist AP5, or of the GluN2A subunit-containing NMDAR antagonist TCN201, 5 min after an ORM reactivation session in the presence of a novel object carried out 24 h post-training impaired retention 24 h later. In contrast, pre-reactivation administration of the GluN2B subunit-containing NMDAR antagonist RO25-6981 had no effect on ORM recall or retention but impeded the amnesia caused by Zif268 silencing and protein synthesis inhibition in dorsal CA1. Our results indicate that GluN2B-containing hippocampal NMDARs are necessary for ORM destabilization whereas GluN2A-containing NMDARs are involved in ORM reconsolidation, and suggest that modulation of the relative activity of these receptor subtypes during recall regulates ORM persistence.

RESUMO

BACKGROUND: Swine production expanded in the last decades. Efforts have been made to improve meat production and to understand its relationship to pig gut microbiota. Copper (Cu) is a usual supplement to growth performance in animal production. Here, two performance studies were conducted to investigate the effects of three different sources of Cu on the microbiota of piglets. A total of 256 weaned piglets were randomly allocated into 4 treatments (10 replicates per treatment of 4 piglets per pen in Trial 1 and 8 replicates of 3 piglets per pen in Trial 2). Treatments included a control group (fed 10 mg/kg of Cu from CuSO4), a group fed at 160 mg/kg of Copper (II) sulfate (CuSO4) or tri-basic copper chloride (TBCC), and a group fed with Cu methionine hydroxy analogue chelated (Cu-MHAC) at 150, 80, and 50 mg/kg in Phases 1 (24-35 d), 2 (36-49 d), and 3 (50-70 d), respectively. At 70 d, the cecum luminal contents from one pig per pen were collected and polled for 16 S rRNA sequencing (V3/V4 regions). Parameters were analyzed in a completely randomized block design, in which each experiment was considered as a block. RESULTS: A total of 1337 Operational Taxonomic Units (OTUs) were identified. Dominance and Simpson ecological metrics were statistically different between control and treated groups (P < 0.10) showing that different Cu sources altered the gut microbiota composition with the proliferation of some bacteria that improve gut health. A high abundance of Prevotella was observed in all treatments while other genera were enriched and differentially modulated, according to the Cu source and dosage. The supplementation with Cu-MHAC can modify a group of bacteria involved in feed efficiency (FE) and short chain fatty acids (SCFA) production (Clostridium XIVa, Desulfovibrio, and Megasphera). These bacteria are also important players in the activation of ghrelin and growth hormones that were previously reported to correlate with Cu-MHAC supplementation. CONCLUSIONS: These results indicated that some genera seem to be directly affected by the Cu source offered to the animals. TBCC and Cu-MHAC (even in low doses) can promote healthy modifications in the gut bacterial composition, being a promising source of supplementation for piglets.

RESUMO

Objective: To evaluate the association of the dietary inflammatory index adjusted for energy (E-DII®) with the evolution of maternal body mass index and human milk lipid (HM) profile in the first 6 months postpartum. Methods: This is a cohort study with 260 Brazilian women (19-43 years old) in the postpartum period. Sociodemographic, gestational, and anthropometric data of the mother were obtained in the immediate postpartum period and in the six monthly meetings. A food frequency questionnaire was applied at baseline and used to calculate the E-DII score. Mature HM was collected, analyzed by gas chromatography coupled with mass spectrometry and the Rose Gottlib method. Generalized estimation equation models were built. Results: Women with >E-DII showed lower adherence to physical activity during pregnancy (p = 0.027), higher frequency of cesarean delivery (p = 0.024), and higher body mass index over time (p < 0.001). At the end of the 6th month, 35 women remained in the study. As for HM, 151 analyses were performed, detecting in the 3rd collection greater fat (%) among those with >E-DII (4.27 ± 1.98 vs. 3.75 ± 2.48; p = 0.003). Conclusion: Diets with >E-DII can impact the type of delivery, change the evolution of maternal nutritional status, and the stability of the lipid profile of HM.

RESUMO

Polymeric nanocapsules (NC) are versatile mixed vesicular nanocarriers, generally containing a lipid core with a polymeric wall. They have been first developed over four decades ago with outstanding applicability in the cosmetic and pharmaceutical fields. Biodegradable polyesters are frequently used in nanocapsule preparation and among them, polylactic acid (PLA) derivatives and copolymers, such as PLGA and amphiphilic block copolymers, are widely used and considered safe for different administration routes. PLA functionalization strategies have been developed to obtain more versatile polymers and to allow the conjugation with bioactive ligands for cell-targeted NC. This review intends to provide steps in the evolution of NC since its first report and the recent literature on PLA-based NC applications. PLA-based polymer synthesis and surface modifications are included, as well as the use of NC as a novel tool for combined treatment, diagnostics, and imaging in one delivery system. Furthermore, the use of NC to carry therapeutic and/or imaging agents for different diseases, mainly cancer, inflammation, and infections is presented and reviewed. Constraints that impair translation to the clinic are discussed to provide safe and reproducible PLA-based nanocapsules on the market. We reviewed the entire period in the literature where the term "nanocapsules" appears for the first time until the present day, selecting original scientific publications and the most relevant patent literature related to PLA-based NC. We presented to readers a historical overview of these Sui generis nanostructures.

RESUMO

Annona crassiflora Mart. (araticum) is an exotic fruit native to the Brazilian Cerrado that stands out for its phytochemical profile, especially for the presence of bioactive compounds. The health-related benefits promoted by these metabolites are widely explored. It is known that the biological activity of bioactive compounds is directly dependent on the availability of the molecules, and their bioaccessibility after the digestion process is one of the main limiting factors. The present study aimed to evaluate the bioaccessibility of bioactive compounds in some parts of araticum (peel, pulp and seeds) fruits obtained from different regions through the in vitro digestion process simulating the gastrointestinal tract. The total phenolic content ranged from 480.81 to 1007.62 for pulp; 837.53 to 1926.56 for peel; and 358.28 to 1186.07 for seeds (mg GAE.100 g-1 of sample). The highest antioxidant activity was observed for the seeds by the DPPH method, the peel by the ABTS method, and most of the peel, except for the Cordisburgo sample, by the FRAP method. Through the research of the chemical profile, it was possible to list up to 35 compounds, including the nutrients, in this identification attempt. It was observed that some compounds were listed only in natura samples (epicatechin and procyanidin) and others only for the bioaccessible fraction (quercetin-3-O-dipentoside), which is justified by the different gastrointestinal tract conditions. Thus, the present study elucidates that the food matrix will directly influence the bioaccessibility of bioactive compounds. In addition, it highlights the potential of unconventionally used or consumed parts that can be used as sources of substances with biological activities, increasing the sustainability by reducing waste.

RESUMO

Subchondral insufficiency fracture of the knee (SIFK) is a non-traumatic condition that has been, historically, associated with the elderly. Early diagnosis and management are essential to prevent evolution to subchondral collapse and secondary osteonecrosis, developing prolonged pain and functional losses. This article presents the case of an 83-year-old patient with severe right knee pain with 15 months of evolution, with sudden onset, and no history of trauma or sprain. Upon observation, the patient presented with a limping gait, antalgic posture with the knee in semi-flexion, pain on palpation of the joint medial line, severe pain on passive mobilization, limited joint range of motion, and a positive McMurray test. The X-ray only demonstrated a gonarthrosis grade 1 in the Kellgren and Lawrence classification with medial compartment affection. Due to the exuberant clinical picture with marked functional compromise, as well as clinical radiological dissociation, MRI was requested to rule out SIFK, which was later confirmed. The therapeutic orientation was then adjusted with an indication for non-weight bearing and analgesia, as well as orientation to an orthopedics consultation to request a surgical evaluation. SIFK is difficult to diagnose and may have an unpredictable outcome due to delayed treatment approaches. This clinical case encourages clinicians to consider subchondral fracture in the differential diagnosis of knee pain when an older patient, with subnormal radiographic findings, reports severe knee pain in the absence of overt traumatic injury.

RESUMO

Infections have emerged as a novel target in managing skin and mucosa diseases. Bacterial resistance to antimicrobials and biofilm elimination from surfaces remains a challenge. Because polymeric nanocapsules (NC) can increase antimicrobial activity, this study aimed to produce and characterize NC into chitosan films (CSF). Copaiba essential oil (CO) presents antimicrobial activity and was chosen to load NC. In addition, the antibacterial activity was evaluated to obtain a new biodegradable polymeric platform system with the potential to treat topical diseases associated with bacterial infections. The CO-NC produced by nanoprecipitation presented particle size lower than 250 nm, negative charge, and encapsulation efficiency higher than 70 %. Direct incorporation of CO into CSF (CO-CSF) by casting method worsened the film's characteristics. However, incorporating CO-NC into CSF (CO-NC-CSF) avoided these drawbacks demonstrating improved physical, mechanical, morphological, and topographical properties. FTIR results demonstrated possible intermolecular interactions among the polymers and CO. The CO-NC-CSF and CO-CSF presented antibacterial properties against Staphylococcus aureus, and Pseudomonas aeruginosa, especially the formulation containing 1 % of CO. These results indicated that CO-NC-CSF is a promising candidate for treating skin disorders.

RESUMO

OBJECTIVE: The aim of this study was to assess the dietary inflammatory index (DII) and its association with maternal factors and excess body weight in Brazilian children aged <2 y during complementary feeding. METHODS: This was a cross-sectional study (2016-2019), conducted with 231 mothers and children ages 6 to 24 mo. The food consumption of the mother-child dyad was obtained through the mean of three 24-h recalls, as well as information on the consumption of breast milk. The DII was used to verify the quality of the diet. Children's weight and length were measured, and the weight/height index was calculated. Path analysis was used to assess the interrelationships between variables. Multiple linear regression was conducted to identify the components of the child's DII (C-DII) that contributed the most to explaining its variation. RESULTS: The children had an anti-inflammatory diet (C-DII -0.37 ± 0.91) whereas the mothers had a proinflammatory diet (M-DII +0.24 ± 0.86). Fiber was the nutrient that contributed most to the variations in the C-DII. Approximately 28% of children were overweight. In the pathway analysis, we verified a direct negative effect of education on excess body weight (standardized coefficients [SC], -0.180; P = 0.034) and C-DII (SC, -0.167; P = 0.002); negative direct effect of breastfeeding on the C-DII (SC, -0.294; P < 0.001); and positive direct effect of M-DII on C-DII (SC, 0.119; P = 0.021). CONCLUSION: Children's proinflammatory diet during the period of complementary feeding was associated with maternal proinflammatory diets, lower education, and absence of breastfeeding practice.

RESUMO

Alzheimer's disease (AD) is a neurodegenerative and progressive disease that predominantly affects women and has no cure. Obstacles to the dental care of people with AD differ in each phase, but the dental surgeon should remember to include the caregivers, formal or informal, in the treatment. Some skills need to be considered in the planning process, and dental health indices can be very helpful for the professional to assess the patient's ability to undergo treatment and how the older person can benefit from it. The dental surgeon should evaluate each person's specific needs so that personalized oral hygiene protocols can be established. The suggested adaptations must be by the reality of the older adult with AD, the family context, and daily routine, and they must contemplate the information provided by the caregiver. In this article, we invite the dental surgeon to understand the continuum of AD to properly plan treatment, considering the individual's limitations, future perspectives, and safety, always keeping the older adult free of oral infections and comfortable with his or her oral health condition


A doença de Alzheimer (DA) é neurodegenerativa, de caráter progressivo, afeta predominantemente mulheres e até o momento não possui cura. Os obstáculos para o atendimento odontológico de pessoas com DA são diferentes em cada fase, porém em nenhuma delas o cirurgião-dentista pode esquecer de incluir os cuidadores, formais ou não, no tratamento. Algumas habilidades precisam ser consideradas no processo de planejamento, e os índices odontológicos podem ser de grande utilidade para que o profissional pondere sobre a capacidade de o paciente receber o tratamento e quanto ele pode se beneficiar dele. A avaliação das necessidades específicas para cada indivíduo deve ser conduzida pelo cirurgião-dentista, de forma que seja possível estabelecer os protocolos personalizados de higiene oral. As adaptações sugeridas devem estar de acordo com a realidade da pessoa com DA, de seu contexto familiar, de sua rotina diária, e devem contemplar as informações fornecidas pelo cuidador. O cirurgião-dentista deve compreender o continuum da DA para planejar adequadamente, considerando as limitações, as perspectivas futuras e a segurança do indivíduo, mantendo-o sempre livre de infecções e confortável com sua condição de saúde bucal, em colaboração com seus cuidadores, formais ou informais

RESUMO

Abstract Objectives: to investigate the association between the Índice de Qualidade da Dieta Adaptado para Gestantes (IQDAG) (Quality of Diet Index Adapted for Pregnant Women) with food consumption, lifestyle and health information. Methods: cross-sectional study with 110 pregnant women assisted at a public health service. Sociodemographic, nutritional and health data were collected from medical records. Food consumption was investigated through the usual intake, for a nutritional analysis, DietPro® program version 6.1 was used. Quality ofdiet was assessed using the IQDAG. Multinomial logistic regression was used to investigate an association between food consumption and IQDAG. Results: the average total score of the IQDAG was 61.3 (±26.1), this is the best quality of the diet. After adjusting for age, schooling and physical activity, the highest consumption of vitamin A (OR=1.04; CI95% = 1.02-1.07) and B2 (OR=2.63; CI95% = 1.19-5.70) was associated with a greater chance of having a better quality of diet (3rdtertile of the IQDAG). Conclusions: pregnant women with better quality of diet had higher intakes of vitamins A and B2. However, other population-based studies are suggested to more broadly in verify its association with food consumption and its ability to identify adherence to nutritional recommendations.


Resumo Objetivos: investigar a associação entre o Índice de Qualidade da Dieta Adaptado para Gestantes (IQDAG) com o consumo alimentar e hábitos de vida e informações de saúde. Métodos: estudo transversal com 110 gestantes atendidas em um serviço público de saúde. Os dados sociodemográficos, nutricionais e de saúde foram coletados a partir dos prontuários de atendimento. O consumo alimentar foi investigado por meio do recordatório de ingestão habitual, para a análise nutricional foi utilizado o Programa DietPro® versão 6.1. A qualidade da dieta foi avaliada utilizando o IQDAG. A regressão logística multinomial foi usada para investigar a associação entre o consumo alimentar e IQDAG. Resultados: a média da pontuação total do IQDAG foi 61,3 (±26,1), isto é uma melhor qualidade da dieta. Após ajuste por idade, escolaridade e atividade física, o maior consumo de vitamina A (OR=1,04; IC95%= 1,02-1,07) e B2 (OR= 2,63; IC95%= 1,19-5,70) esteve associado a maior chance da gestante apresentar uma melhor qualidade da dieta (3º tercil do IQDAG). Conclusões: gestantes com melhor qualidade da dieta tiveram maior ingestão das vitaminas A e B2. Entretanto, sugere-se outros estudos de base populacional para verificar de forma mais ampla sua associação com o consumo alimentar e sua capacidade de identificar a adesão as recomendações nutricionais.

RESUMO

Intestinal mucositis (IM) is a frequent adverse effect in anticancer therapy without standard treatment. The oil obtained from sucupira (Pterodon emarginatus) has anti-inflammatory properties, and the soybean lecithin reduces the intestinal toxicity of several xenobiotics. However, their water insolubility impairs the in vivo application. For this reason, we evaluated if the nanoencapsulation of sucupira oil (SO) in lecithin-based nanocapsules (SO-NC) could be a therapeutically effective system for the treatment of IM in murine cisplatin (CDDP)-induced intestinal mucositis model. SO was analyzed by LC-HRMS/MS and HPLC. SO-NC was prepared by nanoprecipitation and characterized using DLS, HPLC, and AFM. Mice body weight and food consumption were assessed daily during experimental mucositis induced by CDDP. The animals were euthanized, and intestinal permeability, inflammatory mediators, and intestinal histology were performed. SO-NC demonstrated adequate characteristics for oral administration as size under 300 nm, IP < 0.3, high EE, and spherical shape. In vitro cytotoxicity performed against RAW 264.7 cell lines resulted in cell viability above 80 % confirming the non-cytotoxic profile of SO (IC50 268 µg/mL) and SO-NC (IC50 118.5 µg/mL) up to 117.2 µg/mL. The untreated mice showed intestinal toxicity after i.p. of CDDP, principally weight loss, increased intestinal permeability, and MPO and TNF-α levels. Surprisingly, the administration of SO to CDDP-mucositis animals did not circumvent the CDDP effects and increased intestinal permeability. However, SO-NC proved efficient in mitigating the experimental intestinal mucositis by improving intestinal epithelium architecture, reducing intestinal permeability, and improving the MPO levels. In conclusion, SO-NC can positively impact intestinal mucositis by promoting mucosal recovery. This is a promising strategy for developing a new treatment for intestinal mucositis.

RESUMO

The Annonaceae family is widely distributed in subtropical and tropical regions. Several species of this family are known for their pharmacological and beneficial properties to human health, mainly attributed to flavonoids. The objective of this work was to carry out an integrative review in order to identify the main flavonoids found in some plant parts belonging to the Annona genus: araticum tree (Annona crassiflora Mart.), graviola tree (Annona muricata), atemoya tree (Annona cherimolia Mill × Annona squamosa L.), pinha tree (Annona squamosa), bananinha tree (Annona leptopetala), and marolinho tree (Annona coriacea). Only articles published between the years 2016 to 2021 that answered the guiding question were considered, in order to obtain recent data. Then, search strategies were designated for each database used: Science Direct, CAPES Periodicals, and Scielo. Most of the studies retrieved from the databases are related to fruits. The results showed that the number of flavonoids identified varies according to the analytical methodology used to identify and quantify the compounds. Quercetin was the most commonly found compound in all fruits of the Annona genus studied, and epicatechin, rutin, and kaempferol were also found to a lesser extent. The presence of these compounds in Annona makes the fruit promising, with potential applicability in the pharmaceutical and food industry.

RESUMO

Trace mineral minerals Zn, Cu, and Mn play important roles in breeder production and progeny performance. The objective of this study was to determine maternal supplementation of trace mineral minerals on breeder production and progeny growth and development. A total of 540 broiler breeders, Cobb 500 (Slow feathering; 0-66 weeks old) were assigned to one of three treatment groups with the same basal diet and three different supplemental trace minerals: ITM-inorganic trace minerals in sulfates: 100, 16, and 100 ppm of Zn, Cu, and Mn respectively; MMHAC -mineral methionine hydroxy analog chelate: 50, 8, and 50 ppm of bis-chelated MINTREX®Zn, Cu and Mn (Novus International, Inc.), and TMAAC - trace minerals amino acid complex: 50, 8, and 50 ppm of Zn, Cu, and Mn. At 28 weeks of age, eggs from breeder treatments were hatched for progeny trial, 10 pens with 6 males and 6 female birds per pen were fed a common diet with ITM for 45 days. Breeder production, egg quality, progeny growth performance, mRNA expression of gut health associated genes in breeder and progeny chicks were measured. Data were analyzed by one-way ANOVA; means were separated by Fisher's protected LSD test. A p-Value ≤ 0.05 was considered statistically different and 0.1 was considered numerical trend. Breeders on ITM treatment had higher (p < 0.05) body weight (BW), weight gain and lower (p < 0.05) feed conversion ratio (FCR) from 0 to 10 weeks, when compared to birds fed MMHAC. MMHAC significantly improved egg mass by 3 g (p < 0.05) and FCR by 34 points (0.05 < p < 0.1) throughout the reproductive period (26-66 weeks) in comparison to ITM. MMHAC improved (p < 0.01) egg yolk color versus (vs.) ITM and TMAAC in all periods, except 28 weeks, increased (p < 0.01) eggshell thickness and resistance vs. TMAAC at 58 weeks, and reduced (p < 0.05) jejunal NF-κB gene expression vs. TMAAC at 24 weeks. There was a significant reduction in tibial dry matter weight, Seedor index and resistance for the breeders that received MMHAC and/or TMAAC when compared to ITM at 18 weeks. Lower seedor index but numerically wider tibial circumference was seen in hens fed MMHAC at 24 weeks, and wider tibial circumference but lower tibial resistance in hens fed TMAAC at 66 weeks. Maternal supplementation of MMHAC in breeder hens increased (p < 0.0001) BW vs. ITM and TMAAC at hatching, reduced (p < 0.05) feed intake vs. ITM at d14 and d28, and improved (p < 0.01) FCR and performance index vs. TMAAC at d28, reduced (p < 0.01) NF-κB gene expression and increased (p < 0.05) A20 gene expression vs. TMAAC on d0 and vs. ITM on d14, reduced (p < 0.05) TLR2 gene expression vs. ITM on d0 and vs. TMAAC on d14, increased (p < 0.05) MUC2 gene expression vs. both ITM and TMAAC on d45 in progeny jejunum. Overall, these results suggest that supplementation with lower levels of MHA-chelated trace minerals improved breeder production and egg quality and reduced breeder jejunal inflammation while maintaining tibial development in comparison to those receiving higher inorganic mineral supplementation, and it also carried over the benefits to progeny with better growth performance, less jejunal inflammation and better innate immune response and gut barrier function in comparison to ITM and/or TMAAC.
