ABSTRACT

Abstract | Introduction: Broccoli (Brassica oleracea) is well known for its properties as an anticancer, antioxidant, and scavenger of free radicals. However, its benefits in enhancing spermatogenesis have not been well established. Objective: To study broccoli aqueous extract effects on sperm factors and the expression of genes Catsper1, Catsper2, Arl4a, Sox5, and Sox9 in sperm factors in mice. Materials and methods: Male mice were divided randomly into six groups: (1) Control; (2) cadmium (3 mg/kg of mouse body weight); (3) orally treated with 200 µl broccoli aqueous extract (1 g ml-1); (4) orally treated with 400 µl of broccoli aqueous extract; (5) orally treated with 200 broccoli aqueous extract plus cadmium, and (6) orally treated with 400 µl of broccoli aqueous extract plus cadmium. We analyzed the sperms factors and Catsper1, Catsper2, Arl4a, Sox5, and Sox9 gene expression. Results: An obvious improvement in sperm count and a slight enhancement in sperm motility were observed in mice treated with broccoli extract alone or with cadmium. Sperm viability was reduced by broccoli extract except for the 200 µl dose with cadmium, which significantly increased it. Interestingly, Arl4a gene expression increased in the 400 µl broccoli- treated group. Likewise, the Arl4a mRNA level in mice treated with cadmium and 200 µl of broccoli extract was higher than in the cadmium-treated mice. Furthermore, broccoli extract enhanced the mRNA level of Catsper2 and Sox5 genes in mice treated with 200 µl and 400 µl broccoli extract plus cadmium compared with the group treated solely with cadmium. Conclusion: The higher sperm count in broccoli-treated mice opens the way for the development of pharmaceutical products for infertile men.


Resumen | Introducción. El brócoli (Brassica oleracea) se conoce por sus propiedades como anticancerígeno, antioxidante y eliminador de radicales libres. Sin embargo, sus beneficios en la espermatogénesis aún no se han determinado suficientemente. Objetivo. Estudiar los efectos del extracto acuoso de brócoli sobre los factores espermáticos y la expresión de los genes Catsper1, Catsper2, Arl4a, Sox5 y Sox9 en ratones. Materiales y métodos. Los ratones machos se dividieron aleatoriamente en seis grupos: 1) control; 2) tratados con cadmio, 3 mg/kg de peso corporal; 3) tratados con 200 µl de extracto acuoso de brócoli (1 g ml-1); 4) tratados con 400 µl de extracto acuoso de brócoli; 5) tratados con 200 µl de extracto acuoso de brócoli más cadmio, y 6) tratados con 400 µl de extracto acuoso de brócoli más cadmio. El extracto acuoso de brócoli se administró por vía oral. Se analizaron los factores espermáticos y la expresión de los genes Catsper1, Catsper2, Arl4a, Sox5 y Sox9. Resultados. Se observó una mejoría obvia en el recuento y una ligera mejoría en la motilidad de los espermatozoides, en ratones tratados con extracto de brócoli solo o con cadmio. La viabilidad de los espermatozoides se redujo con el extracto de brócoli, excepto con la dosis de 200 µl más cadmio, la cual la aumentó significativamente. Curiosamente, la expresión del gen Arl4a aumentó en el grupo tratado con 400 µl del extracto. Asimismo, el ARNm del Arl4a en ratones tratados con cadmio y 200 µl del extracto, fue más abundante que en los ratones tratados solo con cadmio. Además, el extracto de brócoli aumentó la cantidad de ARNm de los genes Catsper2 y Sox5 en ratones tratados con 200 y 400 µl de extracto de brócoli más cadmio, en comparación con el grupo tratado únicamente con cadmio. Conclusión. El mayor número de espermatozoides en ratones tratados con brócoli abre el camino al desarrollo de productos farmacéuticos para hombres infértiles.

ABSTRACT

The E class MADS-box genes SEPALLATA (SEP)-like play critical roles in angiosperm reproductive growth, especially in floral organ differentiation. To analyze the sequence characteristics and spatio-temporal expression patterns of E-function MADS-box SEP-like genes during kale (Brassica oleracea L. var. acephala) flower development, BroaSEP1/2/3 (GenBank No. KC967957, KC967958, KC967960) homologues, three kale SEP MADS-box gene, were isolated from the kale variety 'Fourteen Line' using Rapid amplification of cDNA ends (RACE). Sequence and phylogenetic analysis indicated that these three SEP genes had a high degree of identity with SEP1, SEP2, SEP3 from Brassica oleracea var. oleracea, Brassica rapa, Raphanus sativus and Brassica napus, respectively. Alignment of the predicted amino acid sequences from these genes, along with previously published subfamily members, demonstrated that these genes comprise four regions of the typical MIKC-type MADS-box proteins: the MADS domain, intervening (I) domain and keratin-like (K) domain, and the C-terminal domain SEPⅠ and SEP Ⅱ motif. The longest open reading frame deduced from the cDNA sequences of BroaSEP1, BroaSEP2, and BroaSEP3 appeared to be 801 bp, 759 bp, 753 bp in length, respectively, which encoded proteins of 266, 252, and 250 amino acids respectively. Expression analyses using semi-quantitative RT-PCR and quantitative real-time PCR indicate that BroaSEP1/2/3 are specifically expressed in floral buds of kale during flower development process. The expression levels of the three genes are very different at different developmental stages, also in wild type, mutant flower with increased petals, and mutant flower with decreased petals. These different patterns of gene expression maybe cause the flowers to increase or decrease the petal number.

ABSTRACT

Organic agriculture is distinguished by practices that benefit the environment and support sustainable agriculture. In the present study, leafy kale, Brassica oleracea L. var. acephala DC., was submitted to chemical and organic (castor bean cake and bovine manure) fertilization treatments aiming to verify the influence of these fertilizers on the occurrence of insect pests and natural enemies. The insects were sampled by visual examination of plants and pitfall traps. Brevicoryne brassicae (L.) and Myzus persicae (Sulzer) (Hemiptera: Aphididae) were the phytophagous insects that occurred more significantly in kale, under chemical rather than organic fertilization, whereas Harmonia axyridis (Pallas), Hippodamia convergens (Guérin-Méneville) (Coleoptera: Coccinellidae), Diaeretiella rapae (M'Intosh) (Hymenoptera: Braconidae) and spiders (Arachnida: Araneae) were abundant in kale under organic fertilizer. The study showed that castor bean cake and bovine manure as leafy kale fertilizers can reduce the use of insecticides and provide quality food.(AU)


A agricultura orgânica destaca-se pelo emprego de práticas que beneficiam o meio ambiente e aumentam a sustentabilidade na agricultura. No presente estudo, a couve-de-folha, Brassica oleracea L. var. acephala DC., foi submetida a tratamentos de adubação química e orgânica à base de torta de mamona e esterco bovino para se verificar a influência dos fertilizantes na ocorrência de insetos pragas e inimigos naturais. Os insetos foram amostrados por meio de exame visual de plantas e armadilhas tipo alçapão. Brevicoryne brassicae (L.) e Myzus persicae (Sulzer) (Hemiptera: Aphididae) foram os insetos fitófagos que ocorreram significativamente em maior número em couve sob adubação química que orgânica, enquanto Harmonia axyridis (Pallas), Hippodamia convergens (Guérin-Méneville) (Coleoptera: Coccinellidae), Diaeretiella rapae (M'Intosh) (Hymenoptera: Braconidae) e aranhas (Arachnida: Araneae) foram abundantes em couve sob adubo orgânico. O estudo evidenciou que o uso de torta de mamona e esterco bovino como adubo de couve-de-folha pode reduzir o uso de inseticidas e fornecer alimentos de qualidade.(AU)

ABSTRACT

ABSTRACT BACKGROUND: Vegetables have some beneficial effects on human health due to their antioxidant compounds, like polyphenols. Cooking leads to many physical and chemical changes to plant structure that can alter the phytochemical compounds of vegetables. OBJECTIVES: To investigate the effects of heat treatment and freezing on the antioxidant properties of garlic, onion, broccoli and cauliflower. DESIGN AND SETTING: Experimental in vitro study in a university laboratory. METHODS: Fresh broccoli (Brassica oleracea var. italica), cauliflower (Brassica oleracea var. botrytis), garlic (Allium sativum) and onion (Allium cepa) were obtained from a local store. These vegetables were divided into three treatment groups: raw, heated and frozen. The heat treatment consisted of heating them in a drying oven at 150 °C for 20 minutes. The freezing treatment consisted of keeping them frozen at -20 °C until analysis. The total phenolic content, antioxidant activity and malondialdehyde levels of the vegetables were measured using the Folin-Ciocalteu phenol reagent, 2,2-diphenyl-1-picrylhydrazyl radical scavenging activity and thiobarbituric acid reactive substances, respectively. RESULTS: Heat treatment had deleterious effects on the antioxidant properties of onion and garlic; and it decreased the antioxidant activity of broccoli. Freezing improved the antioxidant activity of broccoli and garlic, but had detrimental effects for cauliflower and onion. CONCLUSIONS: Heat treatment and freezing exhibit different effects on the antioxidant properties of broccoli, cauliflower, garlic and onion. Convenient cooking and storage patterns should be identified for each vegetable, to obtain the best nutritional benefit from the antioxidant compounds of vegetables.

ABSTRACT

PURPOSE: The purpose of this study was to identify nursing interventions for the postpartum breast care of mothers and determine the effectiveness of interventions for breast pain and engorgement by systematic review. METHODS: Eight national and international databases were reviewed to retrieve and collect randomized controlled trial and controlled clinical trial literature published up to March 2015. Two reviewers independently selected the studies and performed data abstraction and validation. The risk of bias was assessed using Cochrane criteria. A meta-analysis of the studies was performed to analyze the data. RESULTS: The meta-analysis showed that breast massage, along with routine breast care, resulted in a 3.52-point reduction in pain on a 10-point visual analogue scale. Meta-analysis of therapy with cold cabbage leaves and routine breast care showed a pain reduction of 0.54 points. Meta-analysis of cold cabbage leaf application in the experimental group versus cold compress therapy in the comparison group showed a pain reduction of 0.44 points. Meta-analysis of cold cabbage leaf application and routine breast care showed an engorgement reduction of 0.67 points. CONCLUSION: The results of the analysis of 12 articles showed that hot and cold compresses, breast massage, and cabbage application were effective for postpartum breast pain and engorgement.

ABSTRACT

PURPOSE: This study examined the associations of Korean fermented cabbage kimchi consumption with the incidence risk of metabolic syndrome and its components in Korean adults.METHODS: We used the community-based cohort data from the 2001 ~ 2012 Korean Genome and Epidemiology Study (KoGES). General characteristics, food group frequencies and nutrient intakes at baseline from 3,560 healthy individuals aged 40 ~ 69 years and the incidence of metabolic syndrome and its component from 2,259 participants, after excluding the data with incomplete anthropometric and blood test, during 10-year follow-up were analyzed. The participants were classified into three groups according to their daily consumption frequency of Korean fermented cabbage kimchi: ‘less than once (< 1/day)’, ‘once or twice (1 ~ 2/day)’, and ‘three times (3/day)’.RESULTS: After controlling for potential confounders such as age, education, income, residence area, alcohol drinking and energy intake, the consumption frequencies of rice and legumes were significantly higher, and the consumption frequency of meat was significantly lower in the 3/day group compared to that of the other two groups in men and women. The average intakes of energy and most nutrients, except fat and cholesterol, were higher in the 3/day group compared to those of the other two groups in men and women. Frequent consumption of kimchi was associated with a lower incidence of metabolic syndrome in all the models (unadjusted, age-adjusted, and multivariable-adjusted models) in women. When examining the multivariable-adjusted model, the hazard ratio for metabolic syndrome was 0.63 (95% CI: 0.47 ~ 0.86) for the 3/day group compared to that of the < 1/day group in women. However, there was no significant association between kimchi consumption and the incidence of metabolic syndrome in men.CONCLUSION: Our results show that consumption of kimchi at every meal was significantly associated with a lower incidence of metabolic syndrome in women.

ABSTRACT

The objective of this study was to develop fermented vegetable juices that possess antidiabetic and antioxidant activities. Lactobacillus plantarum MKHA15 (MKHA15) and Leuconostoc mesenteroides MKSR (MKSR) were applied to ferment onion, cabbage, and tomato juices at 37℃ and 30℃ for 72 h, respectively, and their functionality was tested using the 12 h hour-fermented juice by MKHA15, and 48 h hour-fermented juice by MKSR. Inhibition of α-glucosidase activity was observed in all fermented juices. The onion juice fermented by MKHA15 showed significantly higher α-glucosidase inhibition activity compared to other juices. All juices showed more than 70% inhibition of α-amylase activity. The DPPH radical scavenging activity of onion juice fermented by MKSR showed significantly lower activity than cabbage and tomato juices; however, no difference was observed between the types of starter cultures. The SOD-like activity of cabbage juice fermented by MKSR was the highest among the fermented juices. The juices fermented by MKHA15 showed higher reducing power than those by MKSR. Therefore, we believe that cabbage, onion and tomato juice fermented by MKHA15 and MKSR would be useful in probiotic juices, as they possess antidiabetic and antioxidant activities.

ABSTRACT

O objetivo deste estudo foi desenvolver e caracterizar filme indicador de qualidade de alimentos utilizando amido de banana verde incorporado com extrato de repolho roxo. Os filmes foram desenvolvidos a partir de duas formulações: i) amido de banana sem extrato; ii) amido de banana com extrato. Os filmes foram caracterizados através de análise térmica (TG/DT), ensaio mecânico, espectroscopia por infravermelho (FT-IR), índice de intumescimento e ativação em diferentes pH. Os filmes apresentaram um perfil similar de perda de massa, indicando pouco efeito da incorporação do extrato à sua estabilidade térmica. A incorporação do extrato vegetal promoveu maior resistência mecânica e menor taxa de intumescimento. FT-IR mostrou que não houve interação do extrato com o biopolímero. O filme de amido apresentou sensibilidade à variação do pH. O uso do amido de banana verde combinado com gelatina e extrato de repolho roxo apresenta potencial aplicação como indicador visual de qualidade de alimentos duranteo armazenamento.


The aim of the study was to develop and characterize food quality indicator film using green banana starch incorporated with purple cabbage extract. The films were developed from two formulations: i) banana starch without extract; ii) banana starch with extract. The films were characterized by thermal analysis (TG/DTA), mechanical assay, infrared spectroscopy (FT-IR), swelling index and activation at different pH. The films presented a similar profile of mass loss, indicating that extract did not affect thermal stability. The incorporation of the vegetal extract promoted greater mechanical resistance and a lower rate of swelling. FT-IR showed that there was no interaction of the extract with the biopolymer. The starch film showed sensitivity to pH variation. The use of green banana starch combined with gelatin and purple cabbage extract has potential application as a visual indicator of food quality during storage.

ABSTRACT

Abstract Glycerol from spent oil was processed by transesterification for biodiesel production. Although glycerol contains many types of impurities, it can be used as a C-source for lactic acid production by fungi, such as Rhizopus microsporus. In this study, we found that wild type R. microsporus (LTH23) produced more lactic acid than the mutant strains on cabbage glycerol media (CG media). More lactic acid was produced on CG media than on cabbage extract media (C media) by about two-fold in batch fermentation conditions. In addition, we found that lactic acid production in a fed-batch process was also slightly higher than in a batch process. To study the combined effects of pH, urea, and glycerol waste concentration on lactic acid production, a response surface methodology was used. The optimum pH, urea, and glycerol waste concentrations were pH 6.5, 3.75 g/L, and 17 g/L, respectively. The maximum lactic acid production predicted by this equation model was 4.03 g/L.

ABSTRACT

PURPOSE: The aim of study was to determine the effects of carbohydrate, fat, protein, and fiber contents on glycemic responses in a single food item or meal. METHODS: Glycemic responses were measured in 30 healthy young adults (17 males and 13 females) with various test foods, including rice, egg whites, bean sprouts, olive oil, noodles, prune, broccoli, Korean dishes, Western dishes, and salad dishes, etc. Test foods were designed to contain various carbohydrate, fat, protein, and fiber contents in single or mixed foods or dishes. After 12 hours of fasting, participants consumed test foods, and the glycemic response was measured for a subsequent 120 min (0, 15, 30, 60, 90, and 120 min). Three hundred and fifty three glycemic responses from 62 foods were collected. The incremental area under the curve (AUC) was calculated for each test food for each subject to examine glycemic responses. Statistical analysis was conducted to identify which macronutrient (carbohydrate, fat, protein and fiber) affected the AUC using a mixed model. RESULTS: Carbohydrates (β= 37.18, p < 0.0001) significantly increased while fat (β= −32.70, p = 0.0054) and fiber (β= −32.01, p = 0.0486) significantly reduced the glycemic response. CONCLUSION: It can be concluded that the glycemic response of a meal can be modified depending on the fat and fiber contents of ingredient foods, even though carbohydrate content is maintained.

ABSTRACT

BACKGROUND/OBJECTIVES: Glutathione s-transferase (GST) is involved in the formation of a multigene family comprising phase II detoxification enzymes, involved in the detoxification of reactive oxygen species. This study evaluated whether daily supplementation with kale juice could modulate levels of plasma antioxidant vitamins and oxidative stress-related parameters. We further examined whether this modulation was affected by combined GSTM1 and T1 polymorphisms. SUBJECTS/METHODS: Totally, 84 subclinical hypertensive patients having systolic blood pressure (BP) over 130 mmHg or diastolic BP over 85 mmHg, received 300 mL of kale juice daily for 6 weeks. Blood samples were drawn before start of study and after completion of 6 weeks. RESULTS: After supplementation, we observed significant decrease in DNA damage and increase in erythrocyte catalase activity in all genotypes. Plasma level of vitamin C was significantly increased in the wild/null and double null genotypes. The plasma levels of β-carotene, erythrocyte glutathione peroxidase activity, and nitric oxide were increased only in the wild/null genotype after kale juice supplementation. CONCLUSIONS: The effect of kale juice was significantly greater in the GSTM1 null genotype and wild/null genotype groups, suggesting possibility of personalized nutritional prescriptions based on personal genetics.

ABSTRACT

BACKGROUND/OBJECTIVES: Obesity is a global health problem of significant importance which increases mortality. In place of anti-obesity drugs, natural products are being developed as alternative therapeutic materials. In this study, we investigated the effect of Brassica juncea L. leaf extract (BLE) on fat deposition and lipid profiles in high-fat, high-cholesterol diet (HFC)-induced obese rats. MATERIALS/METHODS: Male Sprague-Dawley rats were divided into four groups (n = 8 per group) according to diet: normal diet group (ND), high-fat/high-cholesterol diet group (HFC), HFC with 3% BLE diet group (HFC-A1), and HFC with 5% BLE diet group (HFC-A2). Each group was fed for 6 weeks. Rat body and adipose tissue weights, serum biochemical parameters, and tissue lipid contents were determined. The expression levels of mRNA and proteins involved in lipid and cholesterol metabolism were determined by reverse transcription polymerase chain reaction and western blot analysis, respectively. RESULTS: The HFC-A2 group showed significantly lower body weight gain and food efficiency ratio than the HFC group. BLE supplementation caused mesenteric, epididymal, and total adipose tissue weights to decrease. The serum levels of triglyceride, total cholesterol, and low-density lipoprotein cholesterol were significantly reduced, and high-density lipoprotein cholesterol was significantly increased in rats fed BLE. These results were related to lower glucose-6-phosphate dehydrogenase, acetyl-coA carboxylase, and fatty acid synthase mRNA expression, and to higher expression of the cholesterol 7α-hydroxylase and low density lipoprotein-receptor, as well as increased protein levels of peroxisome proliferator-activated receptor α. Histological analysis of the liver revealed decreased lipid droplets in HFC rats treated with BLE. CONCLUSIONS: Supplementation of HFC with 3% or 5% BLE inhibited body fat accumulation, improved lipid profiles, and modulated lipogenesis- and cholesterol metabolism-related gene and protein expression.

ABSTRACT

A new species belonging to the genus Alternaria was isolated from the necrotic leaf spots of Brassica rapa subsp. pekinensis in Yuseong district, Daejeon, Korea. It is an occasional isolate, not an etiological agent, which is morphologically similar to A. broccoli-italicae, but differs in conidial size and conidiophore shape. Phylogenetic analysis using the sequence datasets of the internal transcribed spacer (ITS) region of the rDNA, glyceraldehyde-3-phosphate dehydrogenase (gpd), and plasma membrane ATPase genes showed that it is distantly related to A. broccoli-italicae and closely related to Alternaria species in the section Pseudoalternaria, which belonged to a clade basal to the section Infectoriae. Morphologically, the species is unique because it produces solitary conidia or conidial chains (two units), unlike the four members in the section Pseudoalternaria that produce conidia as short branched chains. It exhibits weak pathogenicity in the host plant. This report includes the description and illustration of A. brassicifolii as a new species.

ABSTRACT

BACKGROUND/OBJECTIVES: The purposes of the study were to investigate folate intakes and plasma folate concentrations as well as estimate folate status in Korean healthy adults. SUBJECTS/METHODS: A total of 254 healthy 19- to 64-year-old adults (68 men and 186 women) living in Seoul metropolitan area, Gumi, and Kwangju, Korea participated. Three consecutive 24-hour dietary recalls, information on folate supplementation, and fasting blood samples were collected from the subjects. RESULTS: The mean dietary folate intakes were 587.4 and 499.2 µg dietary folate equivalent (DFE)/day for men and women, respectively. The median dietary intakes of men and women were 566.6 and 474.6 µg DFE/day, respectively. Forty subjects (16.7% of total) less total folate than the estimated average requirement (EAR). Folate intakes of 23.3% of men and 34.8% of women aged 19–29 years did not meet the EAR for folate. Major food sources consumed for dietary folate were baechukimchi (Chinese cabbage kimchi), rice, spinach, eggs, and laver, which provided 44% of dietary folate intake for the subjects. Plasma folate concentrations were 23.4 nmol/L for men and 28.3 nmol/L for women, and this level was significantly lower in men than in women. Approximately 13% of men and 3% of women were folate-deficient, and the percentages of subjects showing folate concentrations lower than 10 nmol/L were 27.9% of men and 6.4% of women. CONCLUSIONS: Folate intakes of Korean adults in this study were generally adequate. However, one-third of young adults had inadequate folate intakes.

ABSTRACT

OBJECTIVES: This study examined the consumption of Han-sik and its association with the years of residence in Korea and the socioeconomic status among Filipino immigrant women of the Filipino Women's Diet and Health Study (FiLWHEL). METHODS: A total of 474 Filipino women married to Korean men were included in the analysis. Their dietary intake was assessed using a single-day 24-hour recall. The participants provided information on the demographics, socioeconomic, and health-related factors through face-to-face interviews. The generalized linear model and logistic regression model were used to examine the association between the socioeconomic status and consumption of Han-sik. RESULTS: The mean age of the participants was 34.3 years old, and the average duration of residence in Korea was 8.2 years. Among 474 Filipino women, a total of 467 consumed Han-sik, with an average of 6.8 food items per day. The Han-sik foods that the participants consumed most frequently were rice, cabbage kimchi, mixed-grain rice, and fried eggs. The average ratio of Han-sik was 58.57%. The ratio of Han-sik showed no significant associations with the years of residence, years of living together with their husband, education levels, total annual family income, or linguistic competence of Korean. However, the ratio of Han-sik use was associated with cohabitation with parents-in-law; the odds ratio (95% confidence interval) was 2.41 (1.18–4.92, p-trend = 0.002) comparing the fourth quartile with the first quartile of the Han-sik ratio. CONCLUSIONS: Filipino immigrant women in the FiLWHEL study consumed a larger number of Han-sik than Philippine foods. In addition, cohabitation with their parents-in-law was associated with the consumption of Han-sik. Further epidemiologic studies will be needed to determine how the diet affects the health and wellbeing of immigrant women in Korea.

ABSTRACT

OBJECTIVES: This study was conducted to analyze the salinity of representative Korean foods high in sodium to generate data for use as a fundamental resource for setting salinity standards in foods. METHODS: A total of 480 foods from 16 representative Korean foods high in sodium were collected from 10 households, 10 industry foodservice establishments, and 10 Korean restaurants in four regions (Capital area, Chungcheong Province, Gyeongsang Province, and Jeolla Province) and analyzed for salinity. RESULTS: Among the foods, stir-fried anchovies (4.07~4.45%) showed the highest salinity, followed by pickled onion (1.86~2.62%), cabbage kimchi (1.83~2.2%), braised burdock and lotus root (1.79~2.17%), and sliced radish kimchi (1.78~1.89%) (p < 0.001). The salinity of kimchi from home meals (2.2%) was significantly higher than that of foodservice (1.83%) and restaurant (1.93%) kimchi (p < 0.05). Salinity in each group of food was highest in kimchi (1.83~2.04%), followed by braised dishes (1.54~1.78%), steamed dishes (1.0~1.22%), stir-fried dishes (1.02~1.18%), and soup or stew (0.74~1.02%) (p < 0.001). The salinity of soup and stew from restaurants (1.02%) was significantly higher than that of home meal (0.84%) and foodservice (0.74%) soup and stew. CONCLUSIONS: Determination of the salinity of representative Korean foods known to be high in sodium by eating place is expected to be useful to establishing guidelines for reduction of salinity.

ABSTRACT

OBJECTIVES: This study examined the consumption of Han-sik and its association with the years of residence in Korea and the socioeconomic status among Filipino immigrant women of the Filipino Women's Diet and Health Study (FiLWHEL). METHODS: A total of 474 Filipino women married to Korean men were included in the analysis. Their dietary intake was assessed using a single-day 24-hour recall. The participants provided information on the demographics, socioeconomic, and health-related factors through face-to-face interviews. The generalized linear model and logistic regression model were used to examine the association between the socioeconomic status and consumption of Han-sik. RESULTS: The mean age of the participants was 34.3 years old, and the average duration of residence in Korea was 8.2 years. Among 474 Filipino women, a total of 467 consumed Han-sik, with an average of 6.8 food items per day. The Han-sik foods that the participants consumed most frequently were rice, cabbage kimchi, mixed-grain rice, and fried eggs. The average ratio of Han-sik was 58.57%. The ratio of Han-sik showed no significant associations with the years of residence, years of living together with their husband, education levels, total annual family income, or linguistic competence of Korean. However, the ratio of Han-sik use was associated with cohabitation with parents-in-law; the odds ratio (95% confidence interval) was 2.41 (1.18–4.92, p-trend = 0.002) comparing the fourth quartile with the first quartile of the Han-sik ratio. CONCLUSIONS: Filipino immigrant women in the FiLWHEL study consumed a larger number of Han-sik than Philippine foods. In addition, cohabitation with their parents-in-law was associated with the consumption of Han-sik. Further epidemiologic studies will be needed to determine how the diet affects the health and wellbeing of immigrant women in Korea.

ABSTRACT

OBJECTIVES: This study was conducted to analyze the salinity of representative Korean foods high in sodium to generate data for use as a fundamental resource for setting salinity standards in foods. METHODS: A total of 480 foods from 16 representative Korean foods high in sodium were collected from 10 households, 10 industry foodservice establishments, and 10 Korean restaurants in four regions (Capital area, Chungcheong Province, Gyeongsang Province, and Jeolla Province) and analyzed for salinity. RESULTS: Among the foods, stir-fried anchovies (4.07~4.45%) showed the highest salinity, followed by pickled onion (1.86~2.62%), cabbage kimchi (1.83~2.2%), braised burdock and lotus root (1.79~2.17%), and sliced radish kimchi (1.78~1.89%) (p < 0.001). The salinity of kimchi from home meals (2.2%) was significantly higher than that of foodservice (1.83%) and restaurant (1.93%) kimchi (p < 0.05). Salinity in each group of food was highest in kimchi (1.83~2.04%), followed by braised dishes (1.54~1.78%), steamed dishes (1.0~1.22%), stir-fried dishes (1.02~1.18%), and soup or stew (0.74~1.02%) (p < 0.001). The salinity of soup and stew from restaurants (1.02%) was significantly higher than that of home meal (0.84%) and foodservice (0.74%) soup and stew. CONCLUSIONS: Determination of the salinity of representative Korean foods known to be high in sodium by eating place is expected to be useful to establishing guidelines for reduction of salinity.

ABSTRACT

Collard greens Brassica oleracea var. acephala is one of the most important horticultural grown in Brazil for human feeding. The caterpillar Ascia monuste orseis (Lepidoptera: Pieridae) stands out among the important pest in Brassicaceae causing severe plant defoliation. The objective of this study was to identify resistant genotypes (antixenosis) in 26 collard greens genotypes to A. monuste orseis. In free-choice test, randomized blocks were used; and in the non-choice test we adopted a completely randomized design. Manteiga de Jundiaí, crespa de Capão Bonito, couve de Arthur Nogueira 1, manteiga I-1811, manteiga de Ribeirão Pires I-1811, orelha-de-elefante and Pires 1 de Campinas presented antixenosis (non-preference for oviposition). Pires 1 de Campinas, manteiga I-1811, manteiga de São José, verde-escura and manteiga de Monte Alegre presented antixenosis (non-preference for feeding). These collard greens genotypes can be directly used by farmers for cultivation or by breeders as donor sources in breeding programs for resistance to A. monuste orseis.(AU)


Brassica oleracea var. acephala (couve comum) é uma das mais importantes olerícolas cultivadas no Brasil para alimentação humana. A lagarta Ascia monuste orseis (Lepidoptera: Pieridae) destaca-se entre as pragas mais significativas no cultivo de Brassicaceae por causar severa desfolha na planta. O objetivo deste trabalho foi identificar, em 26 genótipos de couve comum, fontes de resistência (antixenose) a A. monuste orseis. No teste de livre escolha, adotou-se o esquema casualizado de blocos; e no teste sem chance de escolha o esquema foi inteiramente casualizado. Manteiga de Jundiaí, crespa de Capão Bonito, couve de Arthur Nogueira 1, manteiga I-1811, manteiga de Ribeirão Pires I-1811, orelha-de-elefante e Pires 1 de Campinas apresentaram antixenose (não preferência para oviposição). Pires 1 de Campinas, manteiga I-1811, manteiga de São José, verde-escura e manteiga de Monte Alegre apresentaram antixenose (não preferência para alimentação). Esses genótipos de couve comum podem ser cultivados diretamente por agricultores ou ser usados por melhoristas em programas de melhoramento genético para resistência a A. monuste orseis.(AU)

ABSTRACT

ABSTRACT The intercropping is a production system that aims to provide increased yield with less environmental impact, due to greater efficiency in the use of natural resources and inputs involved in the production process. An experiment was carried out to evaluate the agronomic viability of kale and New Zealand spinach intercropping as a function of the spinach transplanting time. (0, 14, 28, 42, 56, 70, 84 and 98 days after transplanting of the kale). The total yield (TY) and yield per harvest (YH) of the kale in intercropping did not differ from those obtained in monoculture. The spinach TY was influenced by the transplanting time, the earlier the transplanting, the higher the TY. The spinach YH was not influenced by the transplanting time, but rather by the cultivation system. In intercropping, the spinach YH was 13.5% lower than in monoculture. The intercropping was agronomically feasible, since the land use efficiency index, which was not influenced by the transplanting time, had an average value of 1.71, indicating that the intercropping produced 71% more kale and spinach than the same area in monoculture. Competitiveness coefficient, aggressiveness and yield loss values showed that kale is the dominating species and spinach is the dominated.
