A Scientific Assessment of Sociodemographic Factors, Physical Activity Level, and Nutritional Knowledge as Determinants of Dietary Quality among Indo-Mauritian Women
Yashvee Dunneram,Rajesh Jeewon
Journal of Nutrition and Metabolism , 2013, DOI: 10.1155/2013/572132
Abstract: A healthy diet is of particular concern throughout the life of women to avoid many chronic illnesses especially during their 30s to 50s. There are published data on dietary quality and its determinants among women, but there is a lack of similar data regarding women in Mauritius. This study aimed to investigate the association between age and dietary quality in relation to sociodemographic factors, physical activity level (PAL) and nutritional knowledge (NK). A survey-based study was conducted in 2012 among Indo-Mauritian women including 117 young ( ), 160 reaching middle age ( ) and 50 middle-aged ( ). Validated questionnaires were used to elicit information on the determinants. A food frequency table consisting of 18 food items was used to assess dietary quality. Univariate and multivariate analyses were used to determine the association between various factors and dietary quality. The mean dietary score of middle-aged women ( ) was closer to recommended dietary guidelines compared to young women ( ), and women reaching middle age ( ). Educational level, PAL, NK, and age were main determinants of dietary quality among Indo-Mauritian women ( ). Younger women with low educational level, PAL, and NK are at risk of poor dietary quality. 1. Introduction Mauritius is a middle-income country with a per capita Gross Domestic Product of US$15,600 PPP in 2012 [1]. It is a multiethnic nation [2] which has experienced rapid economic growth since the 1980s, with amplification in disposable income followed by changes in food consumption and lifestyle patterns similar to the globally observed trend [3, 4]. This shift in nutrition habits has been illustrated by an increase in the consumption of meat, eggs, dairy products, oils, and fats which has led to the rapid increase in the occurrence of overweight, obesity, and associated noncommunicable diseases such as diabetes and cardiovascular problems. Few studies have documented the Mauritian dietary quality [4], but there is a lack of published data on the dietary of women in relation to various determinants. Consuming a healthy diet and having access to a nutritious supply of food are important to good health, as good nutrition is a key factor in the overall health and wellbeing of women [5]. Ensuring proper nutrition among women has several optimistic outcomes because healthy women can fulfil their multiple roles, generating income, ensuring their families’ nutrition, and having healthier children, and thus help progress countries’ socioeconomic development [6].

ISRN Nutrition , 2013, DOI: 10.5402/2013/395125
Abstract: Background. Weight-loss behaviours are highly prevalent among adolescents, and body weight perception motivates weight control practices. However, little is known about the association of body weight perception, and weight control practices among teenagers in Mauritius. The aim of this study is to investigate the relationships between actual body weight, body weight perception, and weight control practices among teenagers. Methods. A questionnaire-based survey was used to collect data on anthropometric measurements, weight perception and weight control practices from a sample of 180 male and female students (90 boys and 90 girls) aged between 13 and 18 years old. Results. Based on BMI, 11.7% of students were overweight. Overall, 43.3% of respondents reported trying to lose weight (61.1% girls and 25.6% boys). Weight-loss behaviours were more prevalent among girls. Among the weight-loss teens, 88.5% students perceived themselves as overweight even though only 19.2% were overweight. Reducing fat intake (84.6%), exercising (80.8%), and increasing intake of fruits and vegetables (73.1%) and decreasing intake of sugar (66.7%) were the most commonly reported methods to lose weight. Conclusion. Body weight perception was poorly associated with actual weight status. Gender difference was observed in body weight perception. 1. Introduction Despite the increased prevalence of weight concern and weight control practices among teenagers, obesity has been increasing steadily [1, 2]. Females attach much importance on appearance and are preoccupied with their weight from a very young age [3]. They idealise a thin physique. On the other hand, males value a muscular physique, which they often associate with health [4, 5]. To achieve their ideal, teenagers engage in weight control behaviours. Weight control behaviours are precipitated by body weight perception [5]. Body weight perception refers to the personal evaluation of one’s weight as “underweight” or “normal weight” or “overweight” irrespective of actual body mass index [6, 7]. The discrepancy in body weight perception is also known as body image distortion [8]. Teenagers who incorrectly judge their actual body size express a certain degree of body dissatisfaction [9, 10]. Healthy or overweight individuals who perceive themselves as overweight or fat are more likely to engage in weight reduction activities, whereas individuals with an excess body weight who do not perceive themselves overweight will not involve themselves in weight loss behaviours [11, 12]. Teenagers adopt both healthy balanced diet and exercise,

Abstract: We analyzed the Escherichia coli proteome response to the exogenous stress of guanidine hydrochloride using 2-dimensional gel electrophoresis and found that RpoS (RNA polymerase sigma factor) was significantly stress responsive. While under the stress condition the total number of soluble proteins decreased by about 7 %, but a 6-fold increase in the level of RpoS was observed, indicating that RpoS is a stress-induced protein. As an N-terminus fusion expression partner, RpoS increased significantly the solubility of many aggregation-prone heterologous proteins in E. coli cytoplasm, indicating that RpoS is a very effective solubility enhancer for the synthesis of many recombinant proteins. RpoS was also well suited for the production of a biologically active fusion mutant of Pseudomonas putida cutinase.RpoS is highly effective as a strong solubility enhancer for aggregation-prone heterologous proteins when it is used as a fusion expression partner in an E. coli expression system. The results of these findings may, therefore, be useful in the production of other biologically active industrial enzymes, as successfully demonstrated by cutinase.Escherichia coli have been widely used as a host to produce valuable commercial, industrial, and therapeutic proteins. There are several disadvantages with this system, however, especially for the expression of eukaryotic proteins. For example, when randomly selected 2,078 full-length genes of Caenorhabditis elegans were expressed in E. coli cytoplasm, only 11% of genes yielded significant amounts of soluble material [1]. Several different approaches have been taken to resolve the solubility problem in the past and include (1) truncation of long multi-domain proteins into short and separate domains [2] ; (2) co-expression of molecular chaperones or foldases [3]; (3) enabled secretion to the periplasm where disulfide bonds can be properly formed with the help of an oxidative environment and Dsb protein families [4]; (4) co-expressio

Abstract: Proper breastfeeding practices are effective ways for reducing childhood morbidity and mortality. While many mothers understand the importance of breastfeeding, others are less knowledgeable on the benefits of breastfeeding and weaning. The aim in here is to assess breastfeeding pattern, infant formula feeding pattern, and weaning introduction in Mauritius and to investigate the factors that influence infant nutrition. 500 mothers were interviewed using a questionnaire which was designed to elicit information on infant feeding practices. Statistical analyses were done using SPSS (version 13.0), whereby chi-square tests were used to evaluate relationships between different selected variables. The prevalence of breastfeeding practice in Mauritius has risen from 72% in 1991 to 93.4% as found in this study, while only 17.9% breastfed their children exclusively for the first 6 months, and the mean duration of EBF (exclusive breastfeeding) is 2.10 months. Complementary feeding was more commonly initiated around 4–6 months (75.2%). Despite the fact that 60.6% of mothers initiate breastfeeding and 26.1% of mothers are found to breastfeed up to 2 years, the practice of EBF for the first 6 months is low (17.9%). Factors found to influence infant feeding practices are type of delivery, parity, alcohol consumption, occupation, education, and breast problems. 1. Introduction Adequate nutrition during infancy and early childhood is essential to ensure the growth, health, and development of children to their full potential [1]. It has been recognized worldwide that breastfeeding is beneficial for both the mother and child, as breast milk is considered the best source of nutrition for an infant [2]. The World Health Organization (WHO) recommends that infants be exclusively breastfed for the first six months, followed by breastfeeding along with complementary foods for up to two years of age or beyond [3]. Exclusive breastfeeding can be defined as a practice whereby the infants receive only breast milk and not even water, other liquids, tea, herbal preparations, or food during the first six months of life, with the exception of vitamins, mineral supplements, or medicines [4]. The major advantage of exclusive breastfeeding from 4 to 6 months includes reduced morbidity due to gastrointestinal infection [5]. However, many researchers are questioning if there is sufficient evidence to confidently recommend exclusive breastfeeding for 6 months for infants in developed countries due to the fact that breast milk may not meet the full energy requirements of the average infant

Abstract: We report simultaneous multi-frequency observing performance at 22 and 43 GHz of the 21-m shaped-Cassegrain radio telescopes of the Korean VLBI Network (KVN). KVN is the first millimeter-dedicated VLBI network in Korea having a maximum baseline length of 480 km. It currently operates at 22 and 43 GHz and planed to operate in four frequency bands, 22, 43, 86, and 129 GHz. The unique quasioptics of KVN enable simultaneous multi-frequency observations based on efficient beam filtering and accuarate antenna-beam alignment at 22 and 43 GHz. We found that the offset of the beams is within <5 arcseconds over all pointing directions of antenna. The dual polarization, cooled HEMT receivers at 22 and 43 GHz result in receiver noise temperatures less than 40 K at 21.25-23.25 GHz and 80 K at 42.11-44.11 GHz. The pointing accuracies have been measured to be 3 arcseconds in azimuth and elevation for all antennas. The measured aperture efficiencies are 65%(K)/67%(Q), 62%(K)/59%(Q), and 66%(K)/60%(Q) for the three KVN antennas, KVNYS, KVNUS, and KVNTN, respectively. The main-beam efficiencies are measured to be 50%(K)/52%(Q), 48%(K)/50%(Q), and 50%(K)/47%(Q) for KVNYS, KVNUS, and KVNTN, respectively. The estimated Moon efficiencies are 77%(K)/90%(Q), 74%(K)/79%(Q), and 80%(K)/86%(Q) for KVNYS, KVNUS, KVNTN, respectively. The elevation dependence of the aperture efficiencies is quite flat for elevations > 20 degrees.

Abstract: Endophytes are fungi associated with plants without causing symptoms, and they are quite diverse and have enormous potential for production of important secondary metabolites for the pharmaceutical industry. In this study, we report for the first time fungi (both endophytes and saprobes) from Antidesma madagascariense, a medicinal plant in Mauritius, in view of identifying potential candidates for screening of fungi for pharmaceutical importance. In addition the phylogenetic placement of fungi recovered from leaves samples was investigated based on rDNA sequence analysis. Most commonly isolated fungi were related to Aspergillus, Guignardia, Fusarium, Penicillium, Pestalotiopsis, and Trichoderma. Phylogenetic analyses revealed that fungi recovered belong to 5 different fungal lineages (Hypocreaceae, Trichocomaceae, Nectriaceae, Xylariaceae, and Botryosphaeriaceae). DNA data from the ITS regions were reliable in classification of all recovered isolates up to genus level, but identification to an exact species name was not possible at this stage. Despite criticisms pertaining to the use of ITS sequence data in molecular systematics, our approach here provides an opportunity to justify the reliability of ITS sequence data for possible identification and discovering of evolutionary scenarios among isolates that do not sporulate under cultural conditions. 1. Introduction Endophytes are fungi that inhabit internal tissues or organs without causing obvious symptoms of tissue damage and have been commonly isolated from many plants [1], and a number of them apparently change their ecological strategies and adopt a saprotrophic lifestyle whenever plants senescence [2]. Although endophytes have wide host ranges, a number of them might be host specific and have been well studied, especially with respect to harvesting their biological properties and as a reservoir for novel and natural bioactive compounds [3]. There has been an increasing interest in isolation of fungal endophytes from plants from many tropical regions. However, research in this aspect in Mauritius is rather scanty. There is only one published paper by Toofanee and Dulymamode [4] who reported that Pestalotiopsis was isolated as the most dominant endophytic fungus from the leaves of Cordemoya integrifolia. In this study, an endemic medicinal plant of Mauritius, Antidesma madagascariense Lam. (Euphorbiaceae), was selected for endophytic screening as it has been well documented that this plant possesses pharmacologically active compounds and phytochemicals that have got antioxidant, antibacterial, and

Abstract: Visual satisfaction of the tourists with a water body is strongly influenced by water clarity, which is in turn influenced by a number of water quality parameters. Visual satisfaction thus stands to benefit from having a water quality management tool that results in better water clarity. A Clarity Suitability Index of Water Quality (CSIWQ), derived from clarity suitability curves of selected water quality parameters, can allow estimation of optimal values for these parameters, while ensuring high visual satisfaction among tourists. The present study used sampling and survey methodologies to investigate water clarity and quality at five tourism fishing ports; simultaneously, tourists’ visual satisfaction with a water body was assessed through a questionnaire based on their perceptions. The relationship between tourists’ visual satisfaction and water clarity was found to be positive and strong, with water clarity having predictive power of 74.2%. The study showed that DO, BOD, TP, and SS were the most critical parameters for water clarity. A continued product approach of CSIWQ was found to be most appropriate for describing the relationship between water clarity and these four parameters. This enabled a CSIWQ Index value to be calculated. With a CSIWQ value of 0.6, water clarity would be more than 2.08 m, and tourists would experience very high satisfaction. CSI curves showed that DO would preferably be 9.0 mg/L, and BOD, TP, and SS less than 0.5 mg/L, 0.12 mg/L, and 45.0 mg/L, respectively. The model thus produced valuable insights for assessing and improving water quality and ensuring high levels of visual satisfaction among tourists in tourism fishing ports. This model identified only four parameters but could be improved by ensuring that other water quality parameters were included, to encourage an increase in the number of tourists and to include monitoring of more pollutant sources.
Appearance’s Aesthetic Appreciation to Inform Water Quality Management of Waterscapes  [PDF]
Lee-Hsueh Lee
Journal of Water Resource and Protection (JWARP) , 2017, DOI: 10.4236/jwarp.2017.913103
Abstract:
The appearance of the water is just one aspect of a waterscape that can be appreciated aesthetically. Water appearance is affected by water clarity and water colour. Here, an aesthetic assessment model of waterscape was suggested. In the model, water clarity and colour have direct effects, whereas water quality and phytoplankton biomass have indirect effects, on tourists’ aesthetic assessment of water bodies. The preferred water colour is aquamarine to blue, regardless of depth of clarity. Water colour ranges from pastel yellow to yellow-green are not favoured by tourists. Four water-quality parameters were correlated with water clarity and phytoplankton biomass. The coefficient of indirect effect of river pollution index on tourists’ aesthetic valuation of aquamarine to blue water colour was -0.457, and for pastel yellow to yellowgreen, it was -0.209. The research results showed observation of water colour could not only reflect waterscape aesthetic value, but also serve as a guide of judging water quality, and the status of phytoplankton benefited to simplify the process of water-quality management for waterscape.

Abstract: Although several studies showed the efficacy and safety from this procedure, the comparative assessment of adipose tissue by cryolipolysis has not been studied until now. Therefore we investigated the quantitative change of cross sectional areas of abdominal SAT (subcutaneous adipose tissue) and VAT (visceral adipose tissue) following cryolipolysis. A prospective study for twelve subjects with a single session of cryolipolysis on abdomen was performed. We assessed for their height, weight, and waist circumferences, body contours by photographs, and the cross sectional areas of visceral and subcutaneous adipose tissues were measured at umbilicus level by computerized tomography for 2 months. The cross sectional areas in SAT reduced from 243.3 ± 24.7 to 238.5 ± 40.7 cm2 at 2 months post-treatment. Those of VAT reduced from 141.3 ± 46.4 to 125.1 ± 42.8 cm2 at 2 months post-treatment. Cross sectional areas of VAT, and waist circumferences were significantly reduced by 16.2 cm2, 4.1 cm respectively. Additionally visual improvement without unexpected adverse events was noted. In conclusion a single session cryolipolysis demonstrated to reduce visceral adipose tissue as well as waist circumferences tissue for 2 months. Further controlled study would be needed to evaluate for reduction of visceral adipose tissue by cryolipolysis.
