Passage Times

The retention times of particulate digesta were measured in two captive dugongs, Dugong dugon (Muller 1776) using inert plastic markers. The mouth-to-anus retention times (146-166 h) were similar to those of the West Indian manatee, and much longer than those of most other herbivorous mammals. This slow gut passage rate may be explained by the dugong's long digestive tract, the low fibre level of the diet and the low food intake. Like the manatee, the dugong appears to have a digestive strategy that is atypical of hindgut fermenters: low-fibre material is retained for extended periods within the long hindgut and almost completely digested.

Toolik Lake

In arctic Toolik Lake, slimy sculpin (Cottus cognatus) rely on a diet of larval chironomids (Diptera: Chironomidae). Dry weight of sculpin gut contents was not correlated with fish wet weight. This finding, combined with age and growth data, suggested that sculpin may be food limited in Toolik Lake, particularly as they approach reproductive size. Since three taxonomically distinct chironomids were digested at similar rates, one chironomid species was used as a marker to measure gut passage. Gut passage rate as a function of temperature fits an inverse quadratic model slightly better than a negative exponential model. Sculpins took approximately 1 d to digest food at typical summer temperatures (8–16 °C), but approximately 2 d at a typical winter temperature (4 °C). Since winter is three times longer than summer, winter feeding by sculpins may have greater impact on chironomid density than summer feeding. If sculpin are important in the diet of other Toolik Lake fishes, they may serve as an important trophic link between benthic and pelagic production.

Nepal is one of the least developed but high remittances recipient countries in the world. Nepal received remittance from US$ 8.1 billion in 2016 and it is ranked 23rd among the remittance receiving countries in the world. Remittance income is one of the major sources of capital formation in the context of Nepal. It is directly related with the labour migration in a country which in return enhances foreign employment. Remittances have become a major contributing factor to increasing household income as well as country’s GDP. About 30 percent of Nepal’s GDP comes in the form of remittance money which is sent home by Nepalese working abroad and it helps to reduce country’s poverty rate. Poverty reduction took place in Nepal from 42 percent (1995/96) to 25.2 percent (2010/11). Nepal’s remittance recipients reached 31.5 percent GDP in 2015. The total amount of remittance in the country is 259 billion and among which 20 percent is internal sources, 11 percent from India and 69 percent from Gulf countries. Remittance received by the households is mainly used for daily consumption (79 percent) and remaining other purposes. Moreover, Nepal’s economic status mostly depends on remittance received which is therefore migration driven economy.

Background: Soymilk fermented by lactobacilli and/or bifidobacteria is attracting attention due to the excellent bioavailability of its isoflavones. We investigated the effects of fermented soymilk containing high amounts of isoflavone aglycones on facial wrinkles and urinary isoflavones in postmenopausal women in a randomized, parallel-group, open-label trial. Healthy Japanese women were randomly divided into active (n = 44, mean age 56.3 ± 0.5) or control (n = 44, mean age 56.1 ± 0.5) groups, who consumed or did not consume a bottle of soymilk fermented by Bifidobacterium breve strain Yakult and Lactobacillus mali for 8 weeks. Maximum depth of wrinkles around the crow’s feet area and other wrinkle parameters were evaluated as primary and secondary endpoints respectively at weeks 0, 4, and 8 during the consumption period. Urinary isoflavone levels were determined by liquid chromatography-mass spectrometry. Results: The active group demonstrated significant improvements in the maximum depth (p=0.015) and average depth (p=0.04) of wrinkles, and significantly elevated urinary isoflavones (daidzein, genistein, and glycitein; each p < 0.001) compared with the control during the consumption period. No serious adverse effects were recorded.Conclusion: These findings suggest that fermented soymilk taken daily may improve facial wrinkles and elevate urinary isoflavones in healthy postmenopausal women.Key words: postmenopausal women; isoflavone; fermented soymilk; phytoestrogen; facial wrinkle

Domestic Hot Water

According to the authors of this paper, the mathematical point of view allows us to see what sometimes cannot be seen from the designer’s point of view. The aim of this study was to estimate the influence of the most important parameters (volume of heat storage tanks, daily consumption of domestic hot water, optical efficiency, heat loss coefficient, and total area of a solar collector) on the thermal power output of solar domestic hot water (SDHW) system in European climatic conditions. Three deterministic mathematical models of these relationships for Madrid, Budapest, and Helsinki were created. The database for the development of these models was carried out using computer simulations made in the TRNSYS software environment. The SDHW system located at the Bialystok University of Technology (Poland) was the source of the measurement results used to validate the simulation model. The mathematical optimization procedure showed that the maximum annual useful energy output that can be obtained from 1 m2 of gross collector area is 1303 kWh in the case of Madrid, 918.5 kWh for Budapest, and 768 kWh for Helsinki weather conditions.

Primary Infertility

Abstract This study assessed the rate of primary infertility and its associated factors among 402,807 currently married women aged 20–49 years in India using National Family Health Survey-4 data collected in 2015–2016. Dietary patterns and selected morbidities were included as independent variables, and socioeconomic variables were considered as covariates. Bivariate and multivariate analyses were done to estimate the prevalence of primary infertility and assess its association with the selected variables, respectively. The rate of primary infertility among currently married women in India in 2015–16 was 1.9% and this was significantly associated with younger age (<35 years), higher age at marriage (≥18 years), urban residence, higher secondary or above education and poverty. The consumption of dairy products (OR = 0.79, CI = 0.73–0.86), dark green leafy vegetables (OR = 0.57, CI = 0.39–0.81) and fruit (OR = 0.88, CI = 0.77–1.01) significantly reduced the odds of primary infertility. Daily consumption of fish and aerated drinks was related to 1.06–1.21 times higher odds of primary infertility. Overweight/obesity, high blood pressure and high blood glucose levels were associated with 1.08–1.21 times elevated odds of primary infertility. Thyroid disorder (OR = 1.38, CI = 1.21–1.60), heart disease (OR = 1.17, CI = 1.16–1.19) and severe anaemia (OR = 1.24, CI = 1.00–1.53) were associated with an increased likelihood of primary infertility among women (OR 1.17–1.39, CI 1.00–1.60). The findings provide compelling evidence that primary infertility among women is related to dietary patterns and morbidities. Interventions and programmes targeting the promotion of healthy diets and lifestyles could be beneficial in addressing the issue of primary infertility among women.

Abstract Background High blood pressure or hypertension is well recognized as an important modifiable risk factor for cardiovascular diseases. Several studies had indicated potassium intake has a blood pressure lowering effect. This study aimed to estimate potassium intake via 24-h urinary potassium excretion and to determine the association between potassium intake and blood pressure among adults in Malaysia. Methods Data for 424 respondents in this study were drawn from MyCoSS, a nationwide cross- sectional study conducted among Malaysians who were 18 years and above. Respondents were recruited using stratified cluster sampling, covering urban and rural areas in each state in Malaysia. Data collection was undertaken from October 2017 until March 2018. A single urine sample was collected over 24 h for quantification of potassium excreted. Information on socio-demography and medical history of the respondents were collected by interviewer-administered questionnaires. Anthropometric measurements were measured using validated equipment. BMI was estimated using measured body weight and height. Digital blood pressure monitor (Omron HBP-1300) was used to measure blood pressure. Descriptive statistics, analysis of variance (ANOVA), and multivariable linear regression were used to analyze the data in SPSS Version 21. Results Mean 24-h urinary potassium excretion for the 424 respondents was 37 mmol (95% CI 36, 38). Gender and ethnicity showed statistically significant associations with 24-h urinary potassium excretion. However, potassium excretion was not significantly associated with blood pressure in this study. Conclusion Potassium intake is very low among the adults in Malaysia. Therefore, further education and promotional campaigns regarding daily consumption of potassium-rich diet and its benefits to health need to be tailored for the Malaysian adult population.

AbstractConsumption of illicit drugs poses health risks to the public and environment. Knowledge on their usage helps better implementations of intervention strategies to reduce drug-related harms in the society and also policies to limit their releases as emerging contaminants to recipient environments. This study aimed to investigate from the daily consumption to treatment efficiency and subsequent discharge of illicit drugs by the Swedish urban populations based on simultaneous collection and analysis of influent and effluent wastewater. Two different weekly monitoring campaigns showed similar drug prevalence in Stockholm and Uppsala, with amphetamine as the most popular drug. Almost all target drug residues were still measurable in effluent wastewater. High removal efficiencies (> 94%) were observed for amphetamine, cocaine and benzoylecgonine, whereas ketamine, 3,4-methylenedioxymethamphetamine (MDMA), mephedrone and methamphetamine were the least removed substances (< 64%), with the highest discharge observed for MDMA in both catchments (~ 3.0 g/day in Uppsala; ~ 18 g/day in Stockholm). Our study provides new insights into short-term changes in the use and related discharge of illicit drugs by urban populations. Such wastewater monitoring can provide useful information to public health, forensic and environmental authorities in planning future intervention and regulation policies.
