It is one of the few multi-purpose crops which can supply grains and tasty leafy vegetables. The grain has ability to grow in the dry and semi-dry lands due to its drought tolerant characteristics. It is rich in protein, lysine, carotenoids, dietary fiber, iron, vitamin C, vitamin A, riboflavin, thiamin, folic acid, calcium etc. Amaranth contain substantial amount of bioactive components such as tocopherol (α, β and γ), DPPH (2, 2-diphenyl-1-picrylhydrazyl), anthocyanins, lutein and other phenolic compounds. The fat in amaranth seed is low but composed of essential fatty acids (linoleic and linolenic). Grain amaranth can be used as a flour ingredient for pancakes, bread, muffins, dumplings, crackers, cookies, puddings, porridge, cakes and as a roasted puffed snack. Vegetable types amaranth (also leaves of grain amaranth) are used to make curry, vegetable salads, steamed salad, boiled soups, stir fried, or baked to taste. The seeds and leaves of amaranth are used as herbal remedies and have nutraceutical value. Because of no gluten content, grain amaranth is valuable carbohydrate source for person having glutin intolerance problem. Seed or leaf of amaranths contains some antinutritional factors, such as saponins, tannins, phytic acid, oxalates, protease inhibitors, nitrates and phytohemagglutinins. Thermal processing in moist environment, prior to food use inactivates the antinutritional factors. The present paper briefly describes crop introduction, botany, chemical and nutritive composition, functional and bioactive components, antinutritional factors and food uses including new findings on functional properties of grain amaranth.","PeriodicalId":12935,"journal":{"name":"Himalayan Journal of Science and Technology","volume":"19 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"89416681","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

From sensory evaluation and statistical analysis 10% corn milk inclusion was selected as the best product (p<0.05). The yoghurt thus prepared using 10% corn milk had total solids 22.04%, moisture content 78.62%, protein 4.84%, fat 3.29%, carbohydrate 12.57%, ash 0.81%, acidity 0.68% and pH 4.58. Both control and 10% corn milk incorporated yoghurts were stored under refrigeration 6±1° C and analyzed at 2 days interval till 10 days. Yoghurts with corn milk and control were organoleptically acceptable up to 10 and 6 days respectively.

The objective of this study was to determine the prevalence of intestinal parasitic infections (IPIs) in the HIV-infected individuals visiting different care centers of Morang and Sunsari districts. The present cross-sectional study was conducted from two different HIV rehabilitation centers and one antiretroviral therapy center from eastern Nepal. A semi structured questionnaires was provided to HIV patients and 149 stool specimens were collected to analyze macroscopically and microscopically for the presence of enteric parasites. Data were analyzed by SPSS version 16. A total of 149 HIV seropositive patients with and without diarrhea were included in the study. Overall prevalence rate of enteroparasites was 19.46%. The prevalence rate of enteric parasites in HIV patients showed higher rate of protozoan infections (58.6%) than helminths (41.4%). High prevalence of parasitic infection was seen in male and also among male in the age groups of 31-40 years. The polyparasitism was not detected. A significant difference (p<0.05) was observed in the level of infection of intestinal parasites between the HIV seropositive with gastrointestinal tract (GIT) symptoms and HIV seropositive without GIT symptoms. The enteric parasitic infections were detected in 19.46% among HIV seropositive patients. Early detection of enteric parasitic infections could help in the management and improvement of the quality of life for HIV-infected individuals.","PeriodicalId":12935,"journal":{"name":"Himalayan Journal of Science and Technology","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81516656","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study was carried out to determine the prevalence and associated risk factors of overweight and obesity among women of child bearing age. A cross sectional study was conducted among 206 women residing in Dharan Sub-Metropolitan city of eastern Nepal. BMI, waist circumference and waist to hip ratio were used as indicators for overweight and obesity based on WHO classification and IDF Classification criteria. Association between socioeconomic factors, dietary factors, physical activity, behavioral factors and health related factors with overweight and obesity among women were assessed by using chi square test. Results showed that 50.48% women were overweight and obese (BMI > 25), while 89% based on WHR and, 75.2% based on waist circumference were abdominally obese. The study also showed that age, marital status, size of family, parity, drinking habit and protein intake were major risk factors for overweight and obesity based on BMI. Abdominal obesity based on waist circumference measurement was associated with age, marital status, parity, TV watching while eating habit, contraceptives use, eating outside and protein intake. The high prevalence of overweight and obesity, and diverse natures of associated risk factors among child bearing age women in Dharan showed that more research in this aspect need to be carried out and concerned agencies should focus on identified risk factors for interventions to reduce existing problems of overweight and obesity among women of reproductive age.","PeriodicalId":12935,"journal":{"name":"Himalayan Journal of Science and Technology","volume":"8 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2018-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73731893","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The experimental data were fitted to six thin layer mathematical models (Newton, Page, Handerson and Pabis, logarithmic, two-term exponential and Midilli et al). The models were evaluated in terms of coefficient of determination (R2), chi square (χ2) and root mean square error (RMSE). The Midilli et al model was best fitted to the experimental data of all the models evaluated. The effective diffusivity was calculated using Fick's diffusion equation, and the value varied from 2.07×10-12 m2/s to 2.643×10-12 m2/s.

A cross-sectional study was conducted in Alka Hospital, Lalitpur, Nepal from February to July, 2014. A total of 353 midstream urine samples were collected from postmenopausal women visiting Alka Hospital, Lalitpur, Nepal. The samples were examined by microscopically and culture methods. The isolated organisms were identified by conventional microbiological methods. Antibiotic susceptibility test was performed by modified Kirby-Bauer disc diffusion method according to CLSI (2011) guidelines. Among 353 urine samples processed, 32 % (113) showed significant bacteriuria. Out of 113 bacterial isolates, the prevalence of gram negative bacteria was 97.3% (110) while that of gram positive was 2.7% (3). The most predominating organisms causing UTI were Escherichia coli (84.9%) followed by Klebsiella pneumoniae (5.3%), Enterococcus faecalis (1.7%), Providencia spp. (1.7%), Klebsiella oxytoca (1.7%), Proteus mirabilis (1.7%), Proteus vulgaris (0.9%), Citrobacter freundii (0.9%) and Staphylococcus aureus (0.9%). Antibiotic susceptibility tests of the isolates showed that, most of the gram negative bacterial isolates were sensitive to Piperacillin+Tazobactam followed by Amikacin, Imipenem and Nitrofurantoin, while they were resistant to Amoxicillin. All gram positive isolates were sensitive to Amoxicillin and resistant to Gentamycin.
