Narrow-leafed lupin (Lupinus angustifolius L.) is used as grain legumes, fodder for livestock and green manure in the world and has a great potential to be developed as a new crop in China. In this study, we assessed the genetic diversity among a set of 109 newly introduced accessions of narrow-leafed lupin using 76 genomic SSR markers. Data analysis suggested that the average gene diversity index and average polymorphism information content (PIC) were 0.4758 and 0.4328, respectively. The mean allele number per loci (Na) was 6.3816. The population structure analysis identified two subgroups based on delta K (ΔK) values. This result is in accordance with that of a PCA. The AMOVA analysis showed that most of molecular variance were within population. These results will be useful to guide the genetic improvement of the narrow-leafed lupin crop in China.

The double burden of under- and overnutrition among Bangladeshi women: Socioeconomic and community-level inequalities.

PLoS One 2019 25;14(7):e0219968. Epub 2019 Jul 25.

Sociology and Psychology Department, University of North Texas at Dallas, Dallas, Texas, United States of America.

Background: The prevalence of overweightness in Bangladesh is increasing, while underweightness also continues to persist. A better understanding of the patterns and socioeconomic risk factors of both conditions, particularly among women, is critical in order to promote the development of interventions to improve maternal health in Bangladesh. This study therefore sought to assess the patterns of under- and overweightness between 2004 and 2014 and to examine the predictors of individual and community-level inequalities of under- and overnutrition in Bangladesh.

Methods: Cross-sectional data of 10, 431, and 16,478 ever-married nonpregnant women aged between 15 and 49 years who did not give birth in the two months preceding the survey were extracted from the 2004 and 2014 Bangladesh Demographic and Health Surveys, respectively. Body mass index was used to measure weight status, and underweightness, at-risk for overweightness, overweightness, and obesity were the main outcome variables. Patterns of nutritional change over time was examined by considering the annual average rate of change. Multilevel multinomial logistic regression and quantile regression were used to identify the inequalities.

Results: In 2014, the age-adjusted prevalence values of underweightness, at-risk for overweightness, overweightness, and obesity were 19.7%, 14.9%, 18.1% and 4.0%, respectively. A higher average annual rate of reduction of underweightness was found among wealthier, highly educated, and wealthier community-living women, while a rate of increase of overweightness was found among poorer, uneducated, and poor community-living women. Individual and community-level inequalities of malnutrition were observed among these populations. In comparison with women living in low wealth communities, women from wealthier communities were at an increased risk of being at-risk for overweightness [adjusted odds ratio (AOR): 1.53, 95% confidence interval (CI): 1.23-1.91], overweight (AOR: 1.60, 95% CI: 1.27-2.00), and obese (AOR: 2.12, 95% CI: 1.42-3.18).

Conclusions: This study suggests the coexistence of a double burden of under- and overnutrition in Bangladesh and that the prevalence of overweightness surpasses that of underweightness. The burdens of under- and overnutrition are strongly associated with women's individual socioeconomic positions and the nature of the community in which they live.

Reduction of cadmium toxicity in wheat through plasma technology.

PLoS One 2019 1;14(4):e0214509. Epub 2019 Apr 1.

Department of Physics, University of Rajshahi, Rajshahi, Bangladesh.

Cadmium (Cd) contamination in plant-derived food is a big concern. This study examines whether and how Ar/O2 and Ar/Air plasma techniques lead to Cd detoxification in wheat. Treatment with Ar/O2 and Ar/Air changed the seed surface and decreased the pH of seeds as well as the cultivation media. Generally, plants subjected to Cd treatment from seeds treated with Ar/O2and Ar/Air plasma showed considerable progress in morphology and total chlorophyll synthesis compared to Cd-treated wheat, suggesting that plasma technology is effective for Cd detoxification. Furthermore, Ar/O2 and Ar/Air plasma treated plants showed a significant decrease in root and shoot Cd concentration, which is consistent with the reduced expression of Cd transporters in the root (TaLCT1 and TaHMA2) compared with the plants not treated with plasma in response to Cd stress. This Cd inhibition is possibly accomplished by the decrease of pH reducing the bioavailability of Cd in the rhizosphere. These observations are in line with maintenance of total soluble protein along with reduced electrolyte leakage and cell death (%) in root and shoot due to Ar/O2 and Ar/Air treatments. Further, Cd-induced elevated H2O2 or oxidative damage in tissues was mainly diminished through the upregulation of antioxidant enzymes (SOD and CAT) and their corresponding genes (TaSOD and TaCAT) induced by Ar/O2 and Ar/Air plasma. Grafting results suggest that root originating nitric oxide signal possibly drives the mechanisms of Cd detoxification due to plasma treatment in wheat. These findings provide a novel and eco-friendly use of plasma technology for the mitigation of Cd toxicity in wheat plants.

Mechanisms and Signaling Associated with LPDBD Plasma Mediated Growth Improvement in Wheat.

Sci Rep 2018 Jul 12;8(1):10498. Epub 2018 Jul 12.

Molecular Plant Physiology Laboratory, Department of Botany, University of Rajshahi, Rajshahi, 6205, Bangladesh.

This study investigates the effect and mechanisms of low pressure dielectric barrier discharge (LPDBD) produced with Ar/O and Ar/Air technique causing biological stimulation leading to improved germination and growth in wheat. Both plasma treatments caused rougher and chapped seed surface along with noticeable improvement in seed germination in wheat. Beside this, seed HO concentration significantly increased compared to controls subjected to Ar/O and Ar/Air while this phenomenon was more pronounced due to Ar/Air plasma. Analysis of plants grown from the plasma treated seeds showed significant improvement in shoot characteristics, iron concentration, total soluble protein and sugar concentration in comparison with the controls more efficiently due to Ar/O plasma than that of Ar/Air. Further, none of the plasma treatments caused membrane damage or cell death in root and shoot of wheat. Interestingly, Ar/O treated plants showed a significant increase (2-fold) of HO compared to controls in both root and shoot, while Ar/Air plasma caused no changes in HO. This phenomenon was supported by the biochemical and molecular evidence of SOD, APX and CAT in wheat plants. Plants derived from Ar/O treated seeds demonstrated a significant increase in SOD activity and TaSOD expression in roots of wheat, while APX and CAT activities along with TaCAT and TaAPX expression showed no significant changes. In contrast, Ar/Air plasma caused a significant increase only in APX activity in the shoot. This suggests that Ar/O plasma caused a slight induction in HO accumulation without triggering the HO scavengers (APX and CAT) and thus, efficiency affect growth and development in wheat plants. Further, grafting of control and Ar/O treated plants showed a significant increase in shoot biomass and HO concentration in grafts having Ar/O rootstock regardless of the type scion attached to it. It indicates that signal driving Ar/O plasma mediated growth improvement in wheat is possibly originated in roots. Taken together, this paper delivers new insight into the mechanistic basis for growth improvement by LPDBD technique.

Prevalence and Determinants of Contraceptive use among Employed and Unemployed Women in Bangladesh.

Int J MCH AIDS 2016 ;5(2):92-102

Hobby Center for Public Policy, University of Houston, Houston, TX 77204-5021, USA.

Background: Contraceptive use plays a significant role in controlling fertility, particularly in reaching the replacement level of fertility. The association between women's employment status and contraceptive use is poorly studied and understood in Bangladesh. The aim of this study was to determine the factors that influence contraceptive use among employed and unemployed women in Bangladesh.

Methods: Data and necessary information of 16,616 married women were extracted from the Bangladesh Demographic and Health Survey (BDHS) 2011. The cross sectional data has been used for univariate analysis, to carry out the description of the variables; bivariate analysis, to find the associations among the variables; and binary logistic regression analysis, to evaluate the effects of selected sociodemographic factors on contraceptive use.

Results: The results revealed that the contraceptive use was found higher among employed women (67%) than that of unemployed women. Women's age, education, region, number of living children, and child preference were found to be significantly associated with current use of contraception among employed women. On the other hand, women's age, education, husband's education, region, residence, religion, number of living children, ever heard about family planning, and child preference were identified as the significant predictors of contraceptive use among unemployed women.

Conclusion And Global Health Implications: A gap in using contraceptives among employed and unemployed women is identified. By creating employment opportunities for women to be enhanced the contraceptive use. Moreover, the sociodemographic factors need to be taken into consideration in formulating policies and implementing programs to increase the contraceptive prevalence rate among women.

Factors affecting the utilisation of postpartum care among young mothers in Bangladesh.

Health Soc Care Community 2011 Mar 29;19(2):138-47. Epub 2010 Sep 29.

Department of Community and Global Health, University of Tokyo, Tokyo, Japan.

This article addresses the hypothesis that predisposing, enabling and need factors of households influence utilisation of postpartum care among the young mothers according to the timing and type of providers. To reach our goal Bangladesh Demographic and Health Survey of 2007 data (n = 2376) were used. Findings revealed that only one-third of the young mothers received postpartum care. Postpartum care by medically trained personnel and within the most critical period (within 48 h after delivery) was found to be very low (25.5 and 16.6%). Regarding postpartum morbidities, only one-fifth to one-half of the women reporting a complication consulted medically trained providers. Indeed, between one third and two thirds did not seek any postpartum care. The highest percentages contacting healthcare providers were for convulsions and the lowest was when the baby's hands or feet came first. The stronger influence of the mother's education and antenatal care on the utilisation of postpartum care is consistent with findings from other studies. Concern of the husband or family about pregnancy complications showed a significant and positive impact on the utilisation of postpartum care. Multivariate analysis showed that mother's age at delivery, residence, education, antenatal care, place of delivery, wealth, husband's occupation, husband's concern about pregnancy complications and mother's permission to go to a health centre alone were likely to affect utilisation of postpartum care services. The results indicate urgent needs in Bangladesh for an awareness-raising program highlighting the importance and availability of postpartum care; for strategies to improve the availability and accessibility of antenatal care services and skilled birth attendance, including focused financial support; for women's education to be given high priority; and to enable women to exercise their rights to control their freedom of movement, own health care and access to economic resources.
