No full textA new approach based on glycemic index was suggested in selecting foods for the diabetes patients. A study on glycemic index of selected tuber foods has been conducted to provide Glycemic Index (GI) of the foods. The tubers including Taro (Xanthosoma violaceum SCHOOT), Yam (Dioscorea aculeata LINN), edible canna (Canna edulis KER), arrowroot (Maranta arundinacea LINN) and sweet potato (Ipomoea balatas POIR) were selected. The foods were analyzed for total sugar and starch after streaming. Ten volunteers (21-23 years old) of the nurse's students of the Panti Rapih Hospital Yogyakarta were provided. They took a night fasting and the blood sample was taken in the next morning. The food tested was given and blood sample was taken at 30, 60, 90 and 120 minutes after meal. Glucose level of the blood was measured and drawn graphically. GI was measured as the area under the postpradial blood glucose curve for a food expressed as a percentage of the area after the consumption of reference food ( bread). The food tested and the reference food contains 50-g available carbohydrate, except for arrowroot and it reference contains 25-g available carbohydrate. It was found that tubers investigated contain 58-76% starch and 1.5-21 % total sugar. Protein and fats varied 3-8% and 0.06-1.45% respectively. With bread as reference food, Glycemic Index of food investigated varied from 14 (arrowroot) to 179 (sweet potato). GI of taro, yam and edible were 95, 90 and 105, respectively

No full textHypoglycemic and hypolidemic properties of Edible podded peas (Pisium sativum LINN) and Soy bean (Glycine max MERR) were evaluated in alloxan-induced diabetic rats. The objectives of this research were to investigate the effects of these legumes on serum glucose, total cholesterol and triacyl glycerol in alloxan-induced diabetic rats. Thirty male Sprague-Dawley (SD) rats (250-300 g) were provided and divided into three groups of ten rats. They were diabetic induced by twice intramuscular injection of alloxan (80 mg/Kg of body weight), then fed with three different diets i.e. Standard (ST), (2) Edible Podded peas (EP) and Soybean (SB) for 28 days. The legumes provided 20 % calorie of total duet calorie. Concentration of serum glucose, total cholesterol and tracyl glycerol were measured before injection and diet intervention (0 day and day 17th) and were monitored in the middle and at the end of diet intervention (day 31st and 45th). It was found that alloxan injection increased serum glucose concentration from 63.5 mg/dL to 281.4 mg/dL, total cholesterol and triacyl glycerol concentration increased from 90.7 mg/dL to 136.6 mg/dL and from 108 mg/dL to 147.5 mg/dL, respectively. In 28 days of diet intervention, EP and SB diets decreased the serum glucose concentration by 145.5 mg/dL (67%) and 142.1 mg/dL (65%), respectively, compared to 125.3 mg/dL (57%) in the ST diet. Total cholesterol decreased by 31% and 27% for EP and SB groups. respectively but only 17% for ST rats. Intervention of the diets also decreased concentration of triacyl glycerol by 9% and 5% for EP and SB diets, respectivelym but increased by 6% for standard (ST) diet
PENGARUH PENGOLAHAN TERHADAP KADAR ORYZANOL DAN KOMPOSISI ASAM LEMAK MINYAK BEKATUL DUA VARIETAS PADI LOKAL
No full texta research on processing of rice bran has been conducted. Two local rice cultivar (Rajalele and Merning) were heated with two heating method i.e. steaming and microwave oven heating. Rice bran were added with water (60% of rice bran weight) and mixed to get semisolid mass. The mass were heated in microwave oven for 5 minutes steamed for 15 minutes and then were extruded and dried in oven at 40-50°C. Rice bran oil was extracted from the dry heated rice bran with hexane. The oil was analyzed for oryzanol and fatty acid composition.
It was found that rajalele rice bran contain higher fat than the Merning rice bran. Rajalele rice bran oil contains a higher oryzanol than Merning rice bran oil. Steaming and microwave heating decrease the oil and oryzanol content of rice brans. The dominant fatty acids of rice bran oil were olete, lonoleate and palmitate, i.e. 35-44%, 36-42%, and 15-19%, respectively. The process decreased small quantities of unsaturated fatty acids
Pengaruh pengolahan terhadap Pati Resisten Pisang Kepok (Musa paradisiaca fa. typica) dan Pisang Tanduk (Musa paradisiaca fa. corniculata)
No full textA study on the effect processing on resistant starch (RS) content and chemical composition of kepok (Musa paradisiaca fa. typica) and tanduk banana (Musa paradisiaca fa. corniculata) has been conducted. Mature banana was steamed, steamed - cooled, steamed - frozen, dried and dried - fried and was analyzed for starch, RS, simple sugars and chemical composition. RS content was determined by enzymatic method. It was found that steaming chaned RS from 6.2 mg/g to 9.5 mg/g (53%) for kepok banana and from 7.5 mg/g to 10.5 mg/g (40%) for tanduk banana. Cooling the steamed banana increased the RS to 6.8 mg/g (kepok) and 9.7 mg/g (tanduk). Freezing of the steamed banana increased the RS content by 30% (8.1 mg/g) and 24% (9.3 mg/g) for kepok and tanduk banana, respectively. RS of kepok and tanduk banana increased after the bananas were dried (15% and 41%) and dried-fried (53% and 55%). Small changes were shown on the chemical composition of the banana after processing, except that frying increased the fat content significantly
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
The Effect of Guava on the Improvement of Lipid Profile in Hypercholesterolemic Rats
Full text linkRed guava is a fruit species with high vitamin C content and the highest fibers, in
particular, soluble fiber (pectin) among tropical fruits and cereals. The soluble fiber is
hypocholesterolemic in the body. Therefore, it has the potential to reduce cholesterol content.
This study aimed to assess the potential of red guava in reducing cholesterol content in
hypocholesterolemic rats. This study applied a pure experiment using a randomized pretestposttest
group design on hypocholesterolemic Sprague Dawley rats. The rats were fed with
0.72 g of red guava and pectin supplement as a comparison. The total cholesterol content,
LDL, HDL and triglyceride were measured by CHOD-PAP and GPO-PAP methods. Data
analysis used t-test and ANOVA with significance rate of 0.05. Red guava intake to the
hypocholesterolemic rats significantly reduced the contents of: total cholesterol to 57.8 mg/dL
(32%), LDL to 25.5 mg/dL (43%), triglyceride to 19.7 mg/dL (18%). Conversely, it
significantly increased HDL content to 10.6 mg/dL (18%). The red guava has proven to give
hypocholesterolemic effect by reducing the total cholesterol LDL and triglyceride; Conversely,
it significantly increased HDL
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
