RESUMO

Caruru (Amaranthus spinosus L) and trapoeraba (Commelina benghalensis) are NCEPs introduced into Brazil and are widely used by certain communities. Given the lack of information on carotenoids, vitamins, and minerals present in A. spinosus and C. benghalensis grown in Brazil, this study aimed to determine the proximate composition and the micronutrient profile of these two NCEPs obtained from family farming in the Middle Doce River (Médio Rio Doce) region in the state of Minas Gerais, Brazil. The proximate composition was evaluated using AOAC methods, vitamin E by HPLC with fluorescence detection, vitamin C and carotenoids by HPLC-DAD, and minerals by atomic emission spectrometry with inductively coupled plasma. In summary, the leaves of A. spinosus exhibited a high content of dietary fiber (10.20 g.100 g-1), potassium (708.8 mg·100 g-1), iron (4.0 mg·100 g-1) and ß-carotene (6.94 mg·100 g-1), while the leaves of C. benghalensis were sources of potassium (1399.31 mg·100 g-1), iron (5.7 mg·100 g-1), calcium (163 mg·100 g-1), zinc (1.3 mg·100 g-1), ascorbic acid (23.61 mg·100 g-1), and ß-carotene (31.33 mg·100 g-1). It was therefore concluded that C. benghalensis and A. spinosus, especially, presented excellent potential as important nutritional sources for human consumption, highlighting the gap existing between the available technical and scientific material, thus making them an important and necessary axis of research.

RESUMO

This study aimed to determine the chemical composition and the vitamin, carotenoid, and mineral profile in dandelion (Taraxacum officinale) collected from the Middle Doce River region (Médio Rio Doce) in the state of Minas Gerais, Brazil. To accomplish this, the physicochemical parameters, such as titratable acidity, pH, and soluble solids were determined, in addition to the evaluation of the plants' proximate composition (moisture, ash, proteins, dietary fibers, and lipids). The vitamin E, carotenoids and vitamin C were determined by HPLC and the minerals were analysed by inductively coupled plasma atomic emission spectrometry. The T. officinale samples presented a low content of macronutrients, a total energy value of 27.88 kcal.100 g-1 FW, a high fiber content (3.7 g.100 g-1 FW), low levels of total vitamin E (43.67 µg.100 g-1 FW), total carotenoids of 11.95 g.100 g-1 FW, and did not present vitamin C in detectable levels. The mineral analysis revealed a high concentration of iron, manganese, copper, zinc, and selenium, and small amounts or traces of aluminium, cadmium, nickel, and chromium. In conclusion, T. officinale was shown to be an important source of nutrients, especially fiber, iron and manganese.

RESUMO

BACKGROUND AND AIMS: Balanophoraceae is one of the most bizarre and biologically interesting plant clades. It groups species with peculiar features that offers an opportunity for investigating several aspects of parasite plant development and morphogenesis. We analysed the development and the mature vegetative body of Lathrophytum peckoltii Eichler, focusing on the formation of the host-parasite interface. Additionally, we analysed how this parasitic interaction causes modifications to the anatomy of Paullinia uloptera Radlk and Serjania clematidifolia Cambess host roots. METHODS: Vegetative bodies of the parasite at different developmental stages were collected while infesting the roots of Sapindaceae vines. Non-parasitized host roots were also collected for comparison. Light, epifluorescence, confocal and scanning electron microscopy were used for the analysis. KEY RESULTS: The initial cells of the vegetative axis divide repeatedly, originating a parenchymatous matrix, which occupies the space from the cortex to the vascular cylinder of the host's root. In the peripheral layers of the matrix, located near the xylem of the host's roots, a few cells initiate the process of wall lignification, originating the parasitic bundle. The vascular cambium of the host's root changes the division plane and becomes composed of fusiform initials, forming the vascular bundle. The vegetative axis presents a dermal tissue similar to a phellem, a parenchymatous matrix and a vascular system with different origins. CONCLUSION: The parasite reproduces by endophytic development, in a manner similar to that observed for endoparasites. The strategy of late cell differentiation could aid the parasite in avoiding early detection and triggering of defence responses by the host. This development causes changes to the host root cambial activity, leading to the establishment of direct, vessel to vessel connection between host and parasite. We associate these changes with the cambium modularity and an influx of parasite-derived hormones into the host cambium.

RESUMO

Bisphenol-A (BPA) is an endocrine disruptor associated with higher risk of insulin resistance, type 2 diabetes, and cardiovascular diseases especially in susceptible populations. Because malnutrition is a nutritional disorder associated with high cardiovascular risk, we sought to compare the effects of short-term BPA exposure on cardiovascular parameters of healthy and protein-malnourished mice. Postweaned male mice were fed a normo- (control) or low-protein (LP) diet for 8 weeks and then exposed or not to BPA (50 µg kg-1 day-1) for the last 9 days. Systolic blood pressure was higher in BPA or LP groups compared with the control group. However, diastolic blood pressure was enhanced by BPA only in malnourished mice. Left ventricle (LV) end diastolic pressure (EDP), collagen deposition, and CTGF mRNA expression were higher in the control or malnourished mice exposed to BPA than in the respective nonexposed groups. Nevertheless, mice fed LP diet exposed to BPA exhibited higher angiotensinogen and cardiac TGF-ß1 mRNA expression than mice treated with LP or BPA alone. Wall:lumen ratio and cross-sectional area of intramyocardial arteries were higher either in the LP or BPA group compared with the control mice. Taken together, our data suggest that short-term BPA exposure results in LV diastolic dysfunction and fibrosis, and intramyocardial arteries inward remodeling, besides potentiate protein malnutrition-induced hypertension and cardiovascular risk.

RESUMO

The impact of maceration and germination on the concentration of bioactive compounds still needs to be evaluated. The stability of B complex vitamins (thiamine, riboflavin, pyridoxine), vitamin E (α, ß, γ, δ tocopherols and tocotrienols), xanthophylls (lutein and zeaxanthin) and flavonoids (3-deoxyanthocyanidins-3-DXAs, flavones and flavanones) was evaluated in sorghum grains subjected to maceration and germination, using High Performance Liquid Chromatography. Maceration and germination reduced thiamine and pyridoxine concentrations (retentions ranging from 3.8 to 50.2%). Riboflavin and Vitamin E concentrations were not affected by maceration. Germination increased riboflavin and reduced vitamin E. 3-DXAs were sensitive to maceration and germination (retentions of 69.6% and 69.9%, respectively). Flavones contents decreased with germination. Our results indicate that, after germination and/or maceration, sorghum had important nutritional and functional value. Thus, its intake, mainly in macerated forms, should be encouraged, since concentrations of riboflavin, vitamin E and flavones were not altered during this processing.

RESUMO

BACKGROUND: Isolated monoliths of granitic and/or gneissic rock rising abruptly from the surrounding landscape are known as inselbergs. Dome-shaped inselbergs are common throughout the Atlantic Forest in south-eastern Brazil, a region known as Sugarloaf Land (SLL). This study aimed to create the first checklist of vascular plant species occurring on lowland inselbergs in SLL, with a focus on vegetation islands. We used information from online databases, our own field sampling and data from previously-published studies. We found 548 vascular plant species (505 angiosperms; 43 ferns and lycophytes) belonging to 69 families and 212 genera. Of all identified species, 536 are native and 12 are naturalised. NEW INFORMATION: We updated the information currently available in Flora do Brasil 2020, as 59% of the angiosperms and 63% of the ferns and lycophytes on our checklist were not previously characterised as occurring on rock outcrops. As a first step towards generating a Virtual Herbarium of lowland inselberg vascular plants, we added barcode vouchers with images available online for 75% of the total number of vascular species. In the official lists of endangered species, 115 angiosperms and five ferns and lycophytes are mentioned. However, the conservation status of many species have not yet been evaluated (77% angiosperms; 88% ferns and lycophytes), thus this list is an important step towards their conservation. The information provided herein is essential for management programmes related to rock outcrops in Brazil as they are facing serious threats to conservation.

RESUMO

Dental implant surgery is a common procedure in oral and maxillofacial surgery practices. Extensive training, skill, and experience allow this procedure to be performed with an atraumatic approach, but like any surgical technique, it is subject to accidents and complications. This is an unusual clinical case of an accidental displacement of an implant into the submandibular space that progressed to Ludwig's angina, and it has not yet been described in the literature. This case report describes a clinical case of dental implant displaced into the submandibular space after healing cap removal. After seven days, it progressed to Ludwig's angina. The removal was performed through extraoral access in the submandibular area by using hemostatic forceps and radioscopic technique. After implant removal, the clinical case showed a satisfactory repair emphasizing the importance of a meticulous clinical planning to achieve an appropriate treatment plan, which is essential for a favorable prognosis. Therefore, prevention and management of displaced objects requires proper planning and surgical technique.

RESUMO

The aim of this study was to perform a Bayesian genomewide association study (GWAS) to identify genomic regions associated with growth traits in Hereford and Braford cattle, and to select Tag-SNPs to represent these regions in low-density panels useful for genomic predictions. In addition, we propose candidate genes through functional enrichment analysis associated with growth traits using Medical Subject Headings (MeSH). Phenotypic data from 126,290 animals and genotypes for 131 sires and 3,545 animals were used. The Tag-SNPs were selected with BayesB (π = 0.995) method to compose low-density panels. The number of Tag-single nucleotide polymorphism (SNP) ranged between 79 and 103 SNP for the growth traits at weaning and between 78 and 100 SNP for the yearling growth traits. The average proportion of variance explained by Tag-SNP with BayesA was 0.29, 0.23, 0.32 and 0.19 for birthweight (BW), weaning weight (WW205), yearling weight (YW550) and postweaning gain (PWG345), respectively. For Tag-SNP with BayesA method accuracy values ranged from 0.13 to 0.30 for k-means and from 0.30 to 0.65 for random clustering of animals to compose reference and validation groups. Although genomic prediction accuracies were higher with the full marker panel, predictions with low-density panels retained on average 76% of the accuracy obtained with BayesB with full markers for growth traits. The MeSH analysis was able to translate genomic information providing biological meanings of more specific gene products related to the growth traits. The proposed Tag-SNP panels may be useful for future fine mapping studies and for lower-cost commercial genomic prediction applications.

RESUMO

The same correspondence between general mechanics and civil engineering is true for biomechanics and surgical implants. Currently, numerous mechanical processes are required until a prosthesis is offered to its target audience. These processes typically require human or animal vertebrae, as well as all the complexity involving such tissues, for example, an ethics committee, the availabilityofmaterials, etc. Thus,finite elementmodels (FEMs) havebecome a great option to carry out biomechanical tests independently from anatomical specimens, and, at the same time, to obtain mathematical data to assist in the general physical understanding. The present review discusses the mechanical principles involved in bioengineering, clarifies the steps for the development of FEMs, and shows application scenarios for thesemodels. To the knowledge of the authors, the present paper is the first review study in Portuguese aimed to health care professionals in a language accessible to them.

RESUMO

This study aimed to evaluate the effect of sorghum intake on body composition and metabolic variables in overweight men. In a randomized controlled crossover study, 24 overweight men (25.6 ±â€¯4.6 years) were randomly allocated into one of two treatments: extruded sorghum or extruded wheat. The study consisted of 2 periods of 8 weeks with at least 4 weeks of washout. Anthropometric, clinical and metabolic risk variables were assessed at baseline and at the end of each intervention period. Extruded sorghum consumption reduced body fat percentage and increased daily carbohydrate and dietary fiber intake when compared to wheat consumption. Also, sorghum increased the serum glutathione peroxidase concentration, but no difference was observed when compared to wheat consumption. Extruded sorghum demonstrated to be a good alternative to control obesity in overweight men.

RESUMO

ABSTRACT: Four most consumed non-conventional vegetables were analyzed raw and after cooking techniques routinely used by family farmers: ora-pro-nobis (Pereskia aculeata Mill.); wild mustard (Sinapis arvensis L.), serralha (Sonchus arvensis L), and capiçova (Erechtites valeriana). Chemical composition was determined according to AOAC. Vitamin C, vitamin E and carotenoids were determined by high-performance liquid chromatography, and phenolic compounds and minerals by spectrophotometry. Vitamin E and carotenoids concentrations were higher in stir fried wild mustard (7.68 mg.100 g-1 and 7.45 mg.100 g-1, respectively). Cooking reduced some minerals concentration in the non-conventional vegetables, but increased vitamins and carotenoids concentrations. The vegetables presented high content of minerals but low protein concentration and total energy content. Non-conventional vegetables can be considered of excellent nutritional value and frequent consumption of these vegetables can contribute to improve the feeding of farmers and their families.


RESUMO: Quatro hortaliças não convencionais mais consumidas foram analisadas cruas e após as técnicas de cocção utilizadas rotineiramente pelos agricultores familiares: ora-pro-nobis (Pereskia aculeata Mill.); mostarda selvagem (Sinapis arvensis L.), serralha (Sonchus arvensis L) e capiçova (Erechtites valeriana). A composição química foi determinada de acordo com a AOAC. A vitamina C, vitamina E e os carotenoides foram determinados por cromatografia líquida de alta eficiência (CLAE), e compostos fenólicos e minerais foram determinados por espectrofotometria. As concentrações de vitamina E e carotenoides foram maiores na mostarda selvagem (7,68 mg.100 g-1e 7,45 mg.100 g-1, respectivamente). A cocção reduziu a concentração de alguns minerais nas hortaliças não convencionais, mas aumentou as concentrações de vitaminas e carotenoides. As hortaliças apresentaram alto teor de minerais, mas baixa concentração protéica e valor energético total. As hortaliças não convencionais podem ser consideradas de excelente valor nutricional. O consumo frequente dessas hortaliças pode contribuir para melhorar a alimentação dos agricultores e suas famílias.

RESUMO

The objective of the present study was to evaluate the accuracy and bias of direct and blended genomic predictions using different methods and cross-validation techniques for growth traits (weight and weight gains) and visual scores (conformation, precocity, muscling, and size) obtained at weaning and at yearling in Hereford and Braford breeds. Phenotypic data contained 126,290 animals belonging to the Delta G Connection genetic improvement program, and a set of 3,545 animals genotyped with the 50K chip and 131 sires with the 777K. After quality control, 41,045 markers remained for all animals. An animal model was used to estimate (co)variance components and to predict breeding values, which were later used to calculate the deregressed estimated breeding values (DEBV). Animals with genotype and phenotype for the traits studied were divided into 4 or 5 groups by random and k-means clustering cross-validation strategies. The values of accuracy of the direct genomic values (DGV) were moderate to high magnitude for at weaning and at yearling traits, ranging from 0.19 to 0.45 for the k-means and 0.23 to 0.78 for random clustering among all traits. The greatest gain in relation to the pedigree BLUP (PBLUP) was 9.5% with the BayesB method with both the k-means and the random clustering. Blended genomic value accuracies ranged from 0.19 to 0.56 for k-means and from 0.21 to 0.82 for random clustering. The analyses using the historical pedigree and phenotypes contributed additional information to calculate the GEBV, and in general, the largest gains were for the single-step (ssGBLUP) method in bivariate analyses with a mean increase of 43.00% among all traits measured at weaning and of 46.27% for those evaluated at yearling. The accuracy values for the marker effects estimation methods were lower for k-means clustering, indicating that the training set relationship to the selection candidates is a major factor affecting accuracy of genomic predictions. The gains in accuracy obtained with genomic blending methods, mainly ssGBLUP in bivariate analyses, indicate that genomic predictions should be used as a tool to improve genetic gains in relation to the traditional PBLUP selection.

RESUMO

PURPOSE: Glycaemic control is essential to prevent the manifestation of diabetes in predisposed individuals and the development of associated comorbidities. It is believed that sorghum may modulate the glucose response. In this study, we investigated the effect of extruded sorghum consumption, and the profile of bioactive compounds, on postprandial glycaemia of a subsequent meal in normal weight and normoglycaemic subjects. METHODS: This was a randomized, single-blind, crossover designed study. After a 12 h overnight fasting, ten subjects reported to the laboratory to participate in four experimental sessions, and consumed one of three sorghum test drinks: sorghum P 3-DXAs (with proanthocyanidins-P and rich in 3-deoxyanthocyanidins-3-DXAs); 3-DXAs (without proanthocyanidins and rich in 3-DXAs); and control (low in 3-DXAs and without proanthocyanidins); or a non-sorghum drink. 30 min later, the subjects consumed a glucose solution (25 g glucose). Glycaemic response was monitored at times 0 (before glucose solution), 15, 30, 45, 60, 90, 120 min (after glucose solution consumption). The incremental areas under the glycaemic curve (iAUC) were calculated by the trapezoidal method. RESULTS: Intake of P 3-DXAs drink before the glucose solution resulted in a postprandial iAUC lower than the other sorghum test drinks. Sorghum drinks minimized the postprandial glycaemia peak. CONCLUSION: Sorghum drinks consumption, especially the P 3-DXAs drink, 30 min before the glucose solution resulted in lower iAUC compared to the non-sorghum drink, leading to a lower glycaemic response.

RESUMO

Não é raro na literatura acadêmica específica haver controvérsias sobre os limites e a própria configuração territorial das regiões metropolitanas no Brasil. Afora a falta de consenso e critérios bem definidos para o estabelecimento desses recortes regionais e político-administrativos, parece relevante considerar o significado da mobilidade pendular como indicador da dinâmica econômica e social metropolitana. O objetivo desse artigo é investigar o nível de integração dos municípios que compõem a Região Metropolitana de Belo Horizonte, tendo como base os fluxos de deslocamentos pendulares. Com informações extraídas dos microdados amostrais do Censo Demográfico 2010, a metodologia apresentada permitiu a proposição, para cada município da região, de um Índice de Integração Regional, derivado da razão de pendularidade interna, razão de conectividade pendular e razão de pendularidade nuclear. Em geral, os resultados indicaram sensíveis diferenças regionais no espaço metropolitano, o que permitiu destacar alguns níveis muito baixos de integração, especialmente para os casos dos municípios de Itatiaiuçu, Itaguara e Baldim.


It is not unusual for specific academic literature to contain controversies regarding the limits and actual territorial configuration of the metropolitan regions in Brazil. Aside from the lack of consensus and well defined criteria to establish these regional and political-administrative outlines, it seems relevant to consider the meaning of commuting as an indicator of the metropolitan social and economic dynamic. The objective of this article is to investigate the level of integration of the municipalities that make up the Metropolitan Region of Belo Horizonte (MRBH), based on the flows of pendular displacement. With information extracted from the sample micro-data of the Demographic Census 2010, the methodology presented made it possible to propose an Index of Metropolitan Integration for each municipality in the region, derived from the Internal Pendularity Ratio, Pendular Connectivity and Nuclear Pendularity In general, the results highlighted some very low levels of integration, especially in the cases of the municipalities of Itatiaiuçu, Itaguara and Baldim.

RESUMO

Sorghum is the fifth most produced cereal in the world and is a source of nutrients and bioactive compounds for the human diet. We summarize the recent findings concerning the nutrients and bioactive compounds of sorghum and its potential impact on human health, analyzing the limitations and positive points of the studies and proposing directions for future research. Sorghum is basically composed of starch, which is more slowly digested than that of other cereals, has low digestibility proteins and unsaturated lipids, and is a source of some minerals and vitamins. Furthermore, most sorghum varieties are rich in phenolic compounds, especially 3-deoxyanthocyanidins and tannins. The results obtained in vitro and in animals have shown that phenolics compounds and fat soluble compounds (polycosanols) isolated from sorghum benefit the gut microbiota and parameters related to obesity, oxidative stress, inflammation, diabetes, dyslipidemia, cancer, and hypertension. The effects of whole sorghum and its fractions on human health need to be evaluated. In conclusion, sorghum is a source of nutrients and bioactive compounds, especially 3-deoxyanthocyanidins, tannins, and polycosanols, which beneficially modulate, in vitro and in animals, parameters related to noncommunicable diseases. Studies should be conducted to evaluate the effects of different processing on protein and starch digestibility of sorghum as well as on the profile and bioavailability of its bioactive compounds, especially 3-deoxyanthocyanidins and tannins. Furthermore, the benefits resulting from the interaction of bioactive compounds in sorghum and human microbiota should be studied.

RESUMO

The sensory acceptance and the content of bioactive compounds of whole-sorghum and whole-wheat breakfast cereals were compared. Sensory acceptance was assessed using the Food Action RatingScale. 3-Deoxyanthocyanidins, flavones and flavanones were determined by high-performance liquid chromatography (HPLC) with diode array detection, and vitamin E by HPLC with fluorescence detection. Total phenolics and antioxidant activity were determined by spectrophotometry. The sorghum breakfast cereal had better sensory acceptance (70.6%) than wheat breakfast cereal (41.18%). Sorghum had higher 3-deoxyanthocyanidin content (100% higher), total phenolic compounds (98.2% higher) and antioxidant activity (87.9% higher) than wheat breakfast cereal. Flavones and flavanones were not detected in both breakfast cereals. Total vitamin E content was 78.6% higher in wheat than in sorghum breakfast cereal. Thus, consumption of whole sorghum breakfast cereal should be encouraged, since it had good sensory acceptance and is a source of bioactive compounds that can promote benefits to human health.

RESUMO

This study evaluated the effect of storage temperature (4, 25 and 40°C) and time on the color and contents of 3-deoxyanthocyanins, total anthocyanins, total phenols and tannins of sorghum stored for 180days. Two genotypes SC319 (grain and flour) and TX430 (bran and flour) were analyzed. The SC319 flour showed luteolinidin and apigeninidin contents higher than the grain and the TX430 bran had the levels of all compounds higher than the flour. The storage temperature did not affect most of the analyzed variables. The content of most of the compounds reduced during the first 60days when they became stable. At day 180, the retention of the compounds in the genotypes SC319 and TX430 ranged from 56.1-77.9% and 67.3-80.1% (3-deoxyanthocyanins), 88.4-93.8% and 84.6-96.8% (total anthocyanins) and 86.7-86.8 and 89.4-100% (phenols) respectively. The retention of tannins ranged from 56.6 to 85.3%. The color of samples remained stable for 120days.

RESUMO

Atualmente os pacientes procuram o consultório odontológico tendo o fator estético como queixa principal, em muito dos casos, trata-se de uma reabilitação complexa em que não só a estética, mas também a função precisam ser restabelecidas. Tendo ciência dessa exigência, os cirurgiões dentistas se deparam com situações clínicas que necessitam de um planejamento interdisciplinar para alcançar um resultado final satisfatório. O presente trabalho discorreu sobre um relato de caso clínico de reabilitação complexa envolvendo cirurgia periodontal, implantes e coroas no arco superior. A paciente apresentava hiperatividade do lábio superior associada a uma depressão subnasal, onde o mesmo se alojava durante o sorriso espontâneo e durante sua fonética rotineira. O plano de tratamento foi estabelecido com associação de técnicas para amenizar o sorriso gengival indesejado (osteoplastia, gengivoplastia e preenchimento da depressão subnasal com cimento ortopédico) conjugada com a instalação de implantes do tipo cone morse para possibilitar uma reabilitação individualizada dos espaços protéticos e coroas metal free à base de dissilicato de lítio com excelentes propriedades adesivas para harmonizar o sorriso (AU).


Currently patients seek the dental clinic having the aesthetic factor as the main complaint. In many cases, it is a complex rehabilitation in which not only the aesthetics, but also the function needs to be reestablished. Aware of this requirement, the dentists face clinical conditions that require an interdisciplinary planning to achieve a satisfactory final result. This paper discusses a clinical case report of complex rehabilitation involving periodontal surgery, implants and crowns in the maxillary arch. The patient presented hyperactivity of the upper lip associated with a subnasal depression where it was staying during the spontaneous smile and during her routine phonetics. The treatment plan was established with combination of techniques to reduce the unwanted gingival smile (osteoplasty, gingivoplasty and subnasal depression filling with orthopedic cement) coupled with the installation of cone morse implants to allow individualized rehabilitation of prosthetic spaces and metal-free lithium disilicate crowns with excellent adhesive properties to harmonize smile (AU).

RESUMO

Feeding is indicative of the nutritional status of children, however micronutrient deficiency is common in this age group. We evaluated the impact of inclusion of rice (Ultra Rice(®) (UR(®))) fortified with iron, zinc, thiamin and folic acid on laboratory measurements and the nutrient intake of children. Ninety-nine preschoolers (2-6 years; 42.6% male) from two preschools participated, one of which received UR(®) added to polished rice as part of school meals (test preschool) and the other received only polished rice (control preschool). Biochemical evaluations were performed before and after four months of intervention. Feeding was assessed by direct weighing of food, complemented by 24-h recalls, and the diet was assessed by the Healthy Eating Index (HEI) adapted to the Brazilian reality. The fortified rice improved the levels of zinc (p < 0.001), thiamine (p < 0.001), folic acid (p = 0.003), mean corpuscular hemoglobin (p < 0.001) and mean corpuscular hemoglobin concentration (p < 0.001). The inadequacy percentages of thiamine, folic acid and iron were lower among preschoolers from the test preschool. This study demonstrated the effectiveness of using UR(®) on laboratory measurements of children. The inadequate intake of thiamine, folic acid and iron was also reduced, making the fortified rice an interesting strategy in school feeding programs.
