Amaranth (Amaranthus), a member of amaranthaceous group of plants, is classified as a pseudo cereal and grown either as a grain crop or as a leafy vegetable. 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.
苋菜(Amaranthus)是苋菜科植物的一员,被归类为伪谷物,既可以作为粮食作物种植,也可以作为叶菜种植。它是为数不多的既能供应粮食又能供应美味叶菜的多用途作物之一。由于其抗旱特性,该谷物具有在干旱和半干旱地区生长的能力。它富含蛋白质、赖氨酸、类胡萝卜素、膳食纤维、铁、维生素C、维生素A、核黄素、维生素b1、叶酸、钙等。苋菜含有大量的生物活性成分,如生育酚(α、β和γ)、DPPH(2,2 -二苯基-1-苦酰肼)、花青素、叶黄素和其他酚类化合物。苋菜籽中的脂肪含量低,但由必需脂肪酸(亚油酸和亚麻酸)组成。谷物苋菜可以用作煎饼、面包、松饼、饺子、饼干、饼干、布丁、粥、蛋糕的面粉成分,也可以用作烤膨化小吃。蔬菜种类苋菜(也是谷物苋菜的叶子)可以用来做咖喱、蔬菜沙拉、蒸沙拉、煮汤、炒或烤。苋菜的种子和叶子被用作草药,具有营养价值。由于不含麸质,苋菜是有麸质不耐症的人的宝贵碳水化合物来源。苋菜种子或叶片含有一些抗营养因子,如皂苷、单宁、植酸、草酸、蛋白酶抑制剂、硝酸盐和植物血凝素。在食品使用前,在潮湿的环境中进行热处理,使抗营养因子失活。本文简要介绍了苋菜的作物引种、植物学、化学和营养成分、功能和生物活性成分、抗营养因子、食品用途等方面的研究进展,包括对籽粒苋菜功能特性的新发现。

Soy corn yoghurt is a vegan friendly product prepared by using soymilk as the major ingredient. The aim of this study was to assess the effect of corn milk addition (0, 10, 20, 25 & 30%) on the quality of soy yoghurt. The samples were subjected to sensory evaluation for consumer acceptability and data were subjected to statistical analysis. 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. Acidity and syneresis increased but pH decreased with storage time in both samples.

Gastrointestinal parasitic infections are the major sources of diarrheal disease in developing countries and Human Immunodeficiency virus (HIV) infected patients are at the most risk. 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.
胃肠道寄生虫感染是发展中国家腹泻疾病的主要来源,感染人类免疫缺陷病毒(HIV)的患者面临的风险最大。本研究的目的是确定在Morang和Sunsari地区不同护理中心就诊的艾滋病毒感染者肠道寄生虫感染(IPIs)的患病率。目前的横断面研究是在尼泊尔东部的两个不同的艾滋病毒康复中心和一个抗逆转录病毒治疗中心进行的。对HIV患者进行半结构式问卷调查,并采集149份粪便标本,进行宏观和微观分析肠道寄生虫的存在。数据采用SPSS version 16进行分析。共有149例伴有或不伴有腹泻的HIV血清阳性患者被纳入研究。肠道寄生虫总患病率为19.46%。HIV患者肠道寄生虫患病率中,原生动物感染率(58.6%)高于蠕虫感染率(41.4%)。男性和31-40岁年龄组的男性寄生虫感染率较高。未检测到多寄生现象。有胃肠道症状的HIV血清阳性组与无胃肠道症状的HIV血清阳性组肠道寄生虫感染水平差异有统计学意义(p<0.05)。在HIV血清阳性患者中,肠道寄生虫感染检出率为19.46%。早期发现肠道寄生虫感染有助于管理和改善艾滋病毒感染者的生活质量。

Overweight and obesity is an emerging public health issue in developed world and is also rapidly increasing in developing world. 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.
超重和肥胖在发达国家是一个新出现的公共卫生问题,在发展中国家也在迅速增加。本研究旨在确定育龄妇女超重和肥胖的患病率及相关危险因素。本文对尼泊尔东部达兰市206名妇女进行了横断面研究。BMI、腰围和腰臀比作为超重和肥胖的指标,依据WHO分类标准和IDF分类标准。采用卡方检验评估社会经济因素、饮食因素、身体活动、行为因素和健康相关因素与女性超重和肥胖的关系。结果显示,50.48%的女性体重超重和肥胖(BMI为bbb25), 89%的女性腰臀比为腹部肥胖,75.2%的女性腰围为腹部肥胖。该研究还表明,年龄、婚姻状况、家庭规模、胎次、饮酒习惯和蛋白质摄入量是超重和肥胖的主要风险因素。根据腰围测量得出的腹部肥胖与年龄、婚姻状况、胎次、边吃边看电视的习惯、避孕药具的使用、户外饮食和蛋白质摄入有关。达兰育龄妇女超重和肥胖的高患病率以及相关危险因素的多样性表明,在这方面需要开展更多的研究,有关机构应侧重于确定的危险因素进行干预,以减少育龄妇女超重和肥胖的现有问题。

We have investigated the effect of surface coordination of atoms on the surface properties of Cd-Ga and Cd-Zn liquid alloys by varying their surface coordination fractions using statistical mechanics model. Surface tension and surface concentration did not have significant effect on the calculation of both surface tension and surface concentration of two alloys. The computation of the concentration fluctuations at the surface revealed that it was sensitive to the surface coordination fractions of both segregating systems. In those alloys we found that the computation of the Warren-Cowley short rang order parameter was influenced by the surface coordination fractions.
采用统计力学模型,通过改变Cd-Ga和Cd-Zn液态合金的表面配位分数,研究了原子表面配位对合金表面性能的影响。表面张力和表面浓度对两种合金表面张力和表面浓度的计算均无显著影响。表面浓度波动的计算表明,它对两种分离体系的表面配位分数都很敏感。在这些合金中,我们发现表面配位分数对Warren-Cowley短程阶参量的计算有影响。

Curry leaves (Murraya koenigii L.) are the sweet smelling leaves of small tree of Rutaceae family native to Southwest Asia. In this study, the effect of temperatures (50, 55 and 60°C) on the drying of curry leaves was investigated. 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. The activation energy and the diffusivity constant were found to be 21.808 kJ/mol and 4.667×10-8 m2/s respectively.

Urinary tract infection (UTI) is one of the most common diseases encountered worldwide and is a major public health problem in terms of morbidity and financial costs. 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. This study showed that higher aged postmenopausal women (>80 years) were at higher risk for UTI than those of lower aged ones (<80 years).
尿路感染(UTI)是世界范围内最常见的疾病之一,在发病率和经济成本方面是一个主要的公共卫生问题。横断面研究于2014年2月至7月在尼泊尔拉利特普尔的Alka医院进行。在尼泊尔拉利特普尔Alka医院就诊的绝经后妇女共收集了353份中游尿液样本。用显微镜和培养法对样品进行了检测。采用常规微生物学方法对分离得到的微生物进行鉴定。药敏试验采用改良Kirby-Bauer盘片扩散法,按照CLSI(2011)指南进行。在处理的353份尿液样本中,32%(113份)显示明显的细菌尿。113株细菌中,革兰氏阴性菌的检出率为97.3%(110株),革兰氏阳性菌的检出率为2.7%(3株)。引起尿路感染的主要病原菌为大肠杆菌(84.9%),其次为肺炎克雷伯菌(5.3%)、粪肠球菌(1.7%)、普罗维登氏菌(1.7%)、氧化克雷伯菌(1.7%)、奇异变形杆菌(1.7%)、寻常变形杆菌(0.9%)、弗氏柠檬酸杆菌(0.9%)和金黄色葡萄球菌(0.9%)。药敏试验结果显示,革兰氏阴性菌对哌拉西林+他唑巴坦最敏感,其次为阿米卡星、亚胺培南和呋喃妥因,对阿莫西林耐药。所有革兰氏阳性分离株对阿莫西林敏感,对庆大霉素耐药。本研究显示高龄绝经后妇女(>80岁)发生UTI的风险高于高龄绝经后妇女(<80岁)。
