RESUMEN

In this study, Eugenia calycina and Eugenia stigmatosa, native Brazilian berries, were explored regarding their proximal composition, bioactive compounds, and antioxidant activities. The edible parts of both fruits presented a low content of lipids, proteins, and carbohydrates, resulting in a low caloric value (<70 kcal/100 g fw). E. stigmatosa fruit showed a high total fiber content (3.26 g/100 g fw), qualifying it as a source of dietary fiber. The sugar profile was mainly monosaccharides (glucose, fructose, and rhamnose). Significant contents of total phenolics and flavonoids, monomeric anthocyanins and, condensed tannins, were observed in both fruits. E. calycina contains a high level of anthocyanins, primarily cyanidin-3-glucoside (242.97 µg/g). Other phenolic compounds were also found, the main ones being rutin and ellagic acid. In contrast, E. stigmatosa is mainly composed of rutin and gallic acid. Furthermore, these fruits showed expressive antioxidant activity, evidenced by ORAC, FRAP, and ABTS. These Eugenia fruits are promising sources of bioactive compounds and have a low caloric and high dietary fiber content, making them interesting options for inclusion in a balanced diet, contributing to the promotion of health and the valorization and conservation of Brazilian biodiversity.

RESUMEN

Therapies to prevent osteoporosis are relevant since it is one of the most common non-communicable human diseases in the world and the most prevalent bone disorder in adults. Since jaboticaba peel extract (JPE) added to the culture medium enhanced the osteogenic potential of mesenchymal stem cells (MSCs) derived from osteoporotic rats, we hypothesized that JPE prevents the development of ovariectomy-induced osteoporosis. Ovariectomized rats were treated with either JPE (30 mg/kg of body weight) or its vehicle for 90 days, starting 7 days after the ovariectomy. Then, the femurs were subjected to microcomputed tomography and histological analyses, and the osteoblast and adipocyte differentiation of MSCs was evaluated. JPE attenuated ovariectomy-induced bone loss, as evidenced by higher bone volume/total volume and trabecular number, along with lower trabecular separation and bone marrow adiposity. These protective effects of JPE on bone tissue are due to its ability to prevent the imbalance between osteoblast and adipocyte differentiation of MSCs, since, compared with MSCs derived from ovariectomized rats treated with vehicle, MSCs treated with JPE exhibited higher gene and protein expression of osteogenic markers and extracellular matrix mineralization, as well as lower gene expression of adipogenic markers. These data highlight the potential therapeutic use of JPE to prevent osteoporosis.

RESUMEN

The rates of overweight and obesity around the world have increased in past years. The body's adipose tissue stimulates the antioxidant and oxidation imbalance capacity at the cellular level. This scenario favors an inflammatory low-grade systemic condition starting with insulin resistance, which in turn may involve diabetes mellitus type 2 and cognitive decline afterward. Neurological diseases have been correlated to senile age diseases over time. This scenario calls for a change in the incidence of obesity in the younger generation. An unhealthy dietary consumption together with sedentary habits might lead to poor gut absorption of nutrients. Several plants and foods have bioactive compounds that can reduce or inhibit radical scavengers, reactive oxygen species, and metal ion complexes that threaten the cerebral defense system. The bitter acids from hops (Humulus lupulus L.) have been demonstrated to have promising effects on lipid and carbohydrate metabolism improvement, reducing inflammatory responses through alpha acids, beta acids, and analogs action. Therefore, the current study aimed to investigate the bioactivity of hop bitter acids in obese and lean mice. For that, a dry hop extract (DHE) was obtained by applying carbon dioxide as the fluid of supercritical extraction. Afterward, seventy-eight male mice of the C57BL/6J strain were weighed and randomly distributed into six groups of 13 animals each according to the diet offered: (NO) normolipidic diet, (NO1) normolipidic diet containing 0.35% alpha acids, (NO2) normolipidic diet containing 3.5% alpha acids, (HP) hyperlipidic diet, (HP1) hyperlipidic diet containing 0.35% alpha acids, and (HP2) hyperlipidic diet containing 3.5% alpha acids. After applying the glycemic tolerance and insulin tolerance tests, a better stabilization of glycemia levels and weight gain among those animals fed with DHE (NO2 and HP2) were observed in comparison to the obese control group (HP) (p < 0.05). There was also an amelioration of antioxidant capacity observed by checking the enzymatic profile by SOD and an apparent mitigation of brain degeneration by checking GSK3ß and p-IRS1 proteins expression (p < 0.05). The y-maze cognitive test applied to highlight possible obesity-harmful animal brains did not indicate a statistical difference between the groups. Although the weekly dietary intake between the obese HP2 group (33.32 ± 4.11, p < 0.05) and control HP (42.3 ± 5.88, p < 0.05) was different. The bioactive compounds present in DHE have demonstrated relevant effects on glycemic control, insulin signaling, and the consequent modulatory action of the obesity-related markers with the brain's inflammatory progression.

RESUMEN

SCOPE: Obesity and insulin resistance constitute risk factors for the development of tauopathies and other neurodegenerative diseases. (Poly)phenol compounds are under study for its role in protecting effects against neural injuries and degeneration. Here, we investigated the effect of Amazonian açai pulp (AP) intake in the prevention of memory and cognitive impairment resulting from a high-fat diet intake in mice. METHODS AND RESULTS: Obesity and insulin resistance was induced with a high-fat diet and supplemented with 2% AP to investigate peripheral insulin resistance, recognition memory and tau protein stability via AKT/GSK3-ß signaling pathway. The consumption of AP for 70 days improved peripheral insulin sensitivity and phosphorylation of AKT/GSK3-ß in mice hippocampi. The animals fed high-fat diets supplemented with AP showed better performance in the novel object recognition test (NOR) in comparison to the H group. Catalase activity and reduced glutathione (GSH) values were improved in the treated mice. CONCLUSIONS: These results suggest that the supplementation of AP can attenuate the effects of high-fat diet consumption in peripheral insulin resistance and improve cognitive behavior.

RESUMEN

Araticum is a native species of the Brazilian Cerrado with a high potential for exploitation. Several studies have stated that araticum is a rich source of phytochemicals with multifaceted biological actions. However, little information is available regarding the characterization of phytochemicals found in the pulp of this fruit. In this context, this study aimed to carry out a comprehensive characterization of phytochemicals present in the araticum pulp using ultra-high-performance liquid chromatography coupled to a quadrupole time-of-flight mass spectrometer (UHPLC-ESI-QTOF-MS/MS). The antioxidant potential of araticum pulp was also evaluated. UHPLC-ESI-QTOF-MS/MS profiling of the phytochemicals allowed for the identification and annotation of 139 phytochemicals, including organic acids, jasmonates, iridoids, phenolic compounds, alkaloids, annonaceous acetogenins, fatty acid derivatives, and other compounds. Among them, 116 compounds have been found for the first time in araticum pulp. Phenolic compounds and their derivatives represented about 59% of the phytochemicals identified in the extract. Moreover, araticum pulp showed high total phenolic compound content and antioxidant activity. The majority of identified phytochemicals have been associated with key roles in the plant's defense mechanisms against biotic and abiotic stress factors in the Cerrado environment. Furthermore, many of these phytochemicals found in the araticum pulp are already widely recognized for their beneficial effects on human health. Our findings showed that the araticum fruit contains different classes of phytochemicals that exert various biological activities, both in the plant itself and in humans.

RESUMEN

Fruit-based beverages have been considered excellent food vehicles for delivering prebiotics. However, the conventional thermal processes currently used to microbiologically and enzymatically stabilize these products may cause significant losses in their sensory, physicochemical, nutritional, and bioactive characteristics. Thus, in this study, we evaluate the effect of different levels of pressure (8, 15, and 21 MPa) and temperature (35 and 55 °C) on the characteristics of an inulin-enriched araticum beverage processed with non-thermal supercritical carbon dioxide (SC-CO2) technology. The temperature showed a significant effect on total soluble solids, pH, particle size distribution, and kinetic stability. In contrast, pressure affected only the particle size distribution. The interaction between pressure and temperature influenced the total soluble solids, pH, and particle size distribution. Color parameters, ζ-potential, and glucose and fructose contents were not modified after all SC-CO2 treatments. Moreover, the SC-CO2 treatments preserved the inulin molecular structure, thus maintaining its prebiotic functionality. Overall, the SC-CO2 treatment did not alter the sensory, nutritional, and functional quality of the beverage, while improving its physical stability during storage. Therefore, non-thermal SC-CO2 treatment can be an alternative to current conventional processes for stabilizing inulin-enriched fruit-based beverages.

RESUMEN

This review addresses the possibilities of using supercritical carbon dioxide (SC-CO2) in the flavor industry in extraction and fractionation processes and its use as a reaction medium to generate aroma esters. The advantages and disadvantages are presented, comparing SC-CO2 processing with traditional methods. The most distinguishable features of SC-CO2 include mild reaction conditions, time savings, fewer toxicity concerns, higher sustainability, and the possibility of modulating solvent selectivity according to the process conditions (such as pressure and temperature). Thus, this review indicates the potential of using SC-CO2 to obtain a high selectivity of compounds that can be applied in aroma technology and related fields.

RESUMEN

Araticum (Annona crassiflora Mart.) is a native and endemic species to Brazilian Cerrado whose fruits have high sensorial, nutritional, bioactive, and economic potential. Its use in local folk medicine, associated with recent scientific findings, has attracted growing interest from different industrial sectors. Therefore, understanding the scientific advances achieved so far and identifying gaps to be filled is essential to direct future studies and transform accumulated knowledge into innovative technologies and products. In this review, we summarize the phytochemical composition, bioactivities, and food products from araticum fruit that have been reported in the scientific literature over the past 10 years. The compiled data showed that araticum fruit parts contain a wide range of bioactive compounds, particularly phenolic compounds, alkaloids, annonaceous acetogenins, carotenoids, phytosterols, and tocols. These phytochemicals contribute to different biological activities verified in araticum fruit extracts/fractions, including antioxidant, anti-inflammatory, anti-Alzheimer, anticancer, antidiabetic, anti-obesity, antidyslipidemic, antinociceptive, hepatoprotective, healing of the cutaneous wound, antibacterial, and insecticide effects. Despite the promising findings, further studies-particularly toxicological (especially, with byproducts), pre-clinical, and clinical trials-must be conducted to confirm these biological effects in humans and assure the safety and well-being of consumers.

RESUMEN

Jaboticaba peel (Myrciaria jaboticaba) is a source of bioactive compounds. We investigated the anticancer activity of ethyl acetate extract (JE1) and hydroethanolic extract (JE2) of Jaboticaba peel against breast cancer. Both JE1 and JE2 inhibited clonogenic potential of MDA-MB-231 cells while JE1 was particularly effective in MCF7 cells. Anchorage-independent growth and cell viability was also inhibited by JE1 and JE2. In addition to growth inhibition, JE1 and JE2 could also inhibit migration and invasion of cells. Interestingly, JE1 and JE2 show selective inhibition towards certain breast cancer cells and biological processes. Mechanistic evaluations showed that JE1 induced PARP cleavage, BAX and BIP indicating apoptotic induction. An elevation of phosphorylated ERK was observed in MCF7 cells in response to JE1 and JE2 along with increased IRE-α and CHOP expression indicating increased endoplasmic stress. Therefore, Jaboticaba peel extracts could be potentially considered for further development for breast cancer inhibition.

RESUMEN

Nutritional interventions have been shown to be an interesting approach for the treatment of chronic diseases, including inflammatory bowel disease (IBD). Persea americana Mill. (avocado), is a potential food to be used for the prevention or treatment of intestinal inflammation, due to its nutritional value and pharmacological effects. In this study we evaluated if the dietary intervention with avocado fruit pulp could as an intestinal anti-inflammatory diet using a trinitrobenzenesulfonic acid (TNBS) model of intestinal inflammation in rats. For this purpose, 5, 10 or 20% of avocado fruit pulp was incorporated in the diet of rats, for 21 days before and 7 days after TNBS-induced intestinal inflammation. Dietary intervention with avocado fruit pulp (20%) decreased the extension of colonic lesions (1.38 ± 0.99 vs. 2.67 ± 0.76 cm), weight/length colon ratio (151.03 ± 31.45 vs. 197.39 ± 49.48 cm), inhibited myeloperoxidase activity (891.2 ± 243.2 vs 1603 ± 158.2 U/g), reduced tumor necrosis factor-α (53.94 ± 6.45 vs. 114.9 ± 6.21 pg/mg), interleukin-1ß (583.6 ± 106.2 vs. 1259 ± 81.68 pg/mg) and interferon gamma (27.95 ± 2.97 vs. 47.79 ± 3.51 pg/mg) levels and prevented colonic glutathione depletion (2585 ± 77.2 vs 1778 ± 167.2 nmol/g). The consumption of enriched diet with 20% avocado pulp by 28 days did not promote any alterations in the biochemical or behavioral parameters evaluated. Avocado showed intestinal anti-inflammatory activity, modulating immune response, and acting as antioxidant. The dietary intervention with avocado was safe, suggesting its potential as a complementary treatment in intestinal inflammation.

RESUMEN

Lung Cancer (LC) is an emergent disease widespread globally. Compared to other types of cancer, LC has one of the lowest survival rates (18%). As some risk factors associated with the development of lung carcinogenesis are still unavoidable, researchers have been trying to find efficient and safe alternatives that can help prevent LC or even attenuate its rapid evolution after diagnosis. Studies with natural products promise to offer biological effects against several types of cancers, including LC. The uncountable types of plant matrices dispersed in nature, or even their extracts, contain a powerful composition of bioactive compounds with promising biological effects on LC. The biomes in Brazil are examples of regions with a great biodiversity of bioactive compounds-rich fruits. Therefore, this review aimed to present the potential anticancer effect of Brazilian native fruits, their fractions, and by-products on LC through the elucidation of the main molecular mechanisms involved. The Brazilian plant matrices discussed here (açaí, achiote, araticum, camu camu, cocoa, jaboticaba, genipap, guarana, and pequi) showed promising evidence by inducing cellular apoptosis, reducing cancer cell viability and tumor growth, and regulating cell cycle.

RESUMEN

The Brazilian Cerrado is home to a large number of native and endemic species of enormous potential, among which we can highlight the cagaita, gabiroba, jatobá-do-cerrado, lobeira, and mangaba. In this review, we report the nutritional and phenolic composition, as well as bioactivities of these five Brazilian Cerrado fruits. The compiled data indicated that these fruits have high nutritional, functional, and economic potential and contribute to the daily intake of macro- and micronutrients, energy, and phenolic compounds by inhabitants of the Cerrado region. Phenolic-rich extracts obtained from these fruits have shown several bioactivities, including antioxidant, anti-inflammatory, antidyslipidemic, antidiabetic, analgesic, anticarcinogenic, hepatoprotective, gastrointestinal protective, and antimicrobial properties. Therefore, these fruits can be explored by the food industry as a raw material to develop food products of high value-added, such as functional foods, and can also be employed as plant sources to obtain bioactive compounds for food, cosmetic, and pharmaceutical purposes.

RESUMEN

The interest in nutritional strategies that may counteract the deleterious oxidative effects induced by strenuous exercises is remarkable. Herein, the impact of white tea (Camellia sinensis) (WT), a polyphenol-rich beverage, on antioxidant status in endurance-trained rats after one session of exhaustive exercise were evaluated. Male Wistar rats were divided into groups, which received: control groups - water, and testing groups - WT1 (0.25%; w/v) or WT2 (0.5%; w/v). Drinks were consumed, ad libitum, for 5 or 10 weeks, concomitantly with the running training. Exhaustive running tests were applied before and after the experimental periods. WT intake increased the serum antioxidant capacity of rats in a dose-dependent manner (P < 0.001), which was unaccompanied by the activity of endogenous antioxidant enzymes SOD, GPx, and GR, and GSH content. Inflammatory markers in serum [IL-1ß (P = 0.004) and IL-6 (P = 0.001)] could be downregulated by tea intake. In liver tissue, lower levels of lipid oxidation (P < 0.05) and improved antioxidant defenses (SOD, GPx, GR, and GSH, P < 0.05) were related to the consumption of WT in both doses, supporting protective effects in this responsible metabolic organ. In conclusion, long-term consumption of WT could be a promising adjuvant to exercise-stress management, emphasizing its ability to regulate antioxidant responses and prevent oxidative tissue damage.

RESUMEN

Breast cancer (BC) is the type of cancer with the highest incidence and mortality rates in women worldwide. Despite its well-established risk factors, BC is following an epidemiological pattern, similar to obesity and other western pandemics, associated to demographic and environmental factors. Food and specific bioactive compounds have been evidenced as key factors in BC status attenuation. Native Brazilian fruits and derived products are rich sources of bioactive compounds, which exert valuable antioxidant, anti-inflammatory, and anticancer effects. Therefore, the aim of this review is to evidence the potential of Brazilian fruits in BC by revealing some of the mechanisms underlaying the anticancer effects of their respective bioactive compounds. The interventions investigated here generally show promising evidence, reducing tumor growth or cancer cell viability, and regulating the cell cycle. Native Brazilian fruits, such as açaí, cocoa, guarana, passionfruit, and pineapple have been associated with the regulation of BC-related molecular biomarkers.

RESUMEN

Pot-pollen is a mixture of pollen and nectar from flowers combined with salivary substances of stingless bees, which together are fermented inside cerumen pots. As pot-pollen is rich in polyphenols, we hypothesized that dietary ingestion could modulate obesity, glucose metabolism, and the gut microbiota in an animal model of diet-induced obesity. Male C57BL/6J mice were fed a low-fat/low-sucrose diet (LF/LS), a HF/HS diet or a HF/HS diet containing 0.1% pot-pollen (HF/HS-PP) for 12 weeks. In HF/HS-fed mice, pot-pollen supplementation decreased fasting blood glucose and increased glucose-stimulated insulin secretion without modifying weight gain, body composition, glucose tolerance, and insulin sensitivity. Intake of pot-pollen resulted in changes of the gut microbiota, including a decrease in the abundance of the Rikenellaceae RC9 gut group and Lactobacillus, and an increase in the abundance of Romboutsia. Correlations between genus abundances and metabolic changes in response to supplementation indicated that the gut microbiota contributed to the positive effects of pot-pollen ingestion on fasting glucose. Pot-pollen supplementation-associated changes in the gut microbiota composition correlated with the lowering of fasting glucose levels without modulating weight gain.

RESUMEN

Jabuticaba is a Brazilian berry known for its therapeutic potential against cancer, obesity, insulin resistance (IR), and others. It is a natural source of bioactive compounds, leading to better glucose metabolism, and attenuating obesity and IR through the reduction of pro-inflammatory status. The present study aimed to observe the prebiotic effect of freeze-dried jabuticaba peel (J) consumption on gut bacteria profile and describe its effects on IR derived from the lipopolysaccharides/Toll-like receptor-4 inflammatory pathway. Jabuticaba peel was chemically characterized, and its bioactive compounds were quantified. Twenty-four C57BL/6 mice were feed with a control diet (n = 6), control diet + J (n = 6), high-fat diet (HF) (n = 6), and HF + J (n = 6) for thirteen weeks. Gut bacteriota (16s RNA sequencing), glucose metabolism (fasting glucose and insulin, OGTT, ITT, HOMA-IR, and ß, QUICKI), and inflammatory status (serum lipopolysaccharide, and protein expression) were assessed. The main bioactive compounds found in J were dietary fiber, and anthocyanins, and its consumption along with a healthy diet reduced the abundance of Firmicutes and Actinobacteriota phyla (p < 0.01), increased the Muribaculaceae and Lachnospiraceae families, and Faecalicatena genus (p < 0.05). The correlation test indicates a negative correlation between the Muribaculaceae and glucose metabolism. Jabuticaba peel is a nutritive source of bioactive compounds with prebiotic effects.

RESUMEN

In a world with eminent scarcity of natural resources and increasing incidence of chronic diseases related to unhealthy eating habits, the search for biologically active and environmentally friendly food products is raising among customers. Agro-industrial by-products have caught special attention from the scientific community for being an available, cost-effective and sustainable source of a wide array of bioactive compounds. Review papers frequently restrain their research to by-products derived from the production of most worldwide consumed crops. Therefore, the aim of this review is to summarize the latest overall research, which focus on the biological potential of agro-industrial by-products and their bioactive compound profile, targeting their application as food ingredients, including not only researches with worldwide consumed crops, but also local foodstuff. A total of 152 research papers, browsed in 2 databases, and involving more than 30 countries were gathered. The richness of bioactive compounds of food by-products from different industries, from fruits to marine products, is ascertained throughout this review. The diversity of food residue being investigated for their nutritional and biological capabilities and the content of specific molecules in each food group are remarkable points. Higher literature reports about fruits by-products may be explained by its wide range of bioactive compounds, especially in Latin American fruits, which includes all flavonoids subclasses, besides betaxanthins, carotenoids and phytosterols. Researchers mainly focus on the quantification of fiber, polyphenols and antioxidant capacity of the investigated by-products, obstructing the investigation of specific biological activities, which are precisely related to the main phytochemicals of the residue matrix, as each molecule has an individual mechanism of action that should be considered when evaluating its biological capabilities. Furthermore, the addition of food by-products has also been advantageous in the production of fortified or enriched bakery, dairy and meat products and functional beverages. All along this literature review, it becomes clearer the high nutritional and nutraceutical value that many by-products possess, besides their attested biological activities, such as antioxidant, anticarcinogenic, antimicrobial, among others.

RESUMEN

Latin America has a wide range of native plants spread through its territory. The palms of the Astrocaryum genus are examples of crops occurring in Central and South America, including the large plant life in Brazil. Although not very well known, the Astrocaryum spp. possess edible and non-edible fractions with potential technological and medicinal uses, as evidenced by recent research. Two native Brazilian fruits, tucumã-do-Amazonas (Astrocaryum aculeatum) and tucumã-do-Pará (Astrocaryum vulgare), typically found in the north and northeast of the country, respectively, stand out for their high antioxidant capacity and rich content in bioactive compounds, mainly carotenoids and phenolic compounds. Accordingly, experimental studies indicate their potential to prevent and treat inflammatory and oxidative stress-related conditions, including cancer. The tucumã plants have also been suggested as tools in the industry, for example for biofuel production, activated carbon technology, and as alternative packaging. Considering the importance of bringing light to underestimated yet culturally relevant native crops with potential benefits for small and large communities, this review aims to present and discuss the characteristics, bioactive composition, health effects, and technological potential of tucumã-do-Amazonas and tucumã-do-Pará fruits.

RESUMEN

We evaluated the impact of yellow passion fruit (Passiflora edulis sp.) bagasse extract (PFBE) administration in systemic oxidative and inflammatory parameters in vivo, considering prostate cancer progression in transgenic mice (TRAMP). Piceatannol, scirpusin-B, dicaffeoylquinic acid, citric acid, and (+)-catechin were identified in PFBE, and the extract showed high in vitro antioxidant capacity. Some alterations in systemic parameters were verified during prostate cancer progression, as the increase in ALT and MDA levels, and SOD and GPx activities in the plasma. In the liver, higher MDA, TNF-α, and NF-κB levels, and GR and GPx activities were verified. Compared to their respective controls, the short- and long-term PFBE administration reduced MDA levels in the liver and plasma. The long-term treatment increased the catalase activity in the plasma, while the short-term treatment increased the hepatic SOD and catalase activities. Still, a reduction in hepatic TNF-α and NF-κB levels was verified after long-term treatment. PRACTICAL APPLICATIONS: Prostate cancer progression is associated with changes in systemic redox status and inflammation markers. Moreover, the intake of polyphenols with antioxidant properties, besides delaying prostate carcinogenesis, may improve the systemic antioxidant defenses and inflammatory response. In vitro studies pointed to a promising antioxidant and anti-inflammatory potential of yellow passion fruit bagasse. However, in vivo studies are scarce. Our results provided information about in vivo impacts of PFBE oral consumption on antioxidant defense and inflammation, indicating its potential as an adjuvant during the initial steps of prostate cancer.

RESUMEN

Consumption of dried berries is increasing worldwide due to their health benefits. This popularity has introduced berry-based supplements as an easier way to take in berry nutrients. The chemical composition of six dried berries (blueberry, cranberry, goji berry, golden berry, maqui berry, and raspberry) were compared to their berry-based supplements by metabolomics using nuclear magnetic resonance spectroscopy (NMR). Thirty-three metabolites were identified and 23 were quantified. Chemometric analysis of berries revealed that goji berry showed the highest content of amino and organic acids, while cranberry and golden berry showed a high carbohydrate content. Fatty acids were predominant in blueberry, golden berry, maqui berry, and raspberry. Additionally, an exploratory analysis of phenolic compounds in berry extracts were conducted. phenolic compounds in berry extracts could be correlated with their antioxidant activity. Additionally, derived supplements did not show similarities with their respective berry, suggesting the minimal addition of dried berry in their formulation. Thus, non-declared additives have highlighted the importance of food safety investigation.
