Background: The prevalence of intimate partner violence (IPV) and its consequences on women's reproductive health and pregnancy outcomes have been well documented. Bangladesh is burdened with the high prevalence of IPV and induced abortion/menstrual regulation. Understanding their association may benefit strategies to reduce termination of pregnancy (TOP). Therefore, this study assesses the association between experience of IPV and TOP among married Bangladeshi women age 15-49 years. Methods: This cross-sectional study is based on data from 10,146 married women of reproductive age from the Bangladesh Demographic Health Survey, 2007 (BDHS). A subset of interviews from currently married women, living with a husband and who had at least one pregnancy in the last 5 years (n = 1875) were extracted. Results: Results of this study showed that among the respondents, 31.4 % experienced physical and/or sexual IPV: 13.4 % experienced only sexual violence and 25.8 % experienced only physical violence. 21.0 % respondents ever had a TOP and 5.8 % had a TOP in last 5 years. Physical IPV was significantly associated with both TOP ever (OR = 1.36; 95 % CI: 1.05-1.77) and TOP in last 5 years (OR = 1.72; 95 % CI: 1.11-2.06). Conclusions: Prevention of intimate partner violence which was associated with pregnancy termination may reduce the high incidence of termination of pregnancies in Bangladesh. © 2015 Rahman.

Considering the human health risk due to the consumption of foodstuffs, the concentrations of heavy metals (lead, manganese, chromium, cadmium, and arsenic) are investigated in vegetables, fruits, and fish species collected from the central market (called Shaheb Bazar) of Rajshahi City, Bangladesh. The foodstuffs examined for metal constituents are the basis of human nutrition in the study area. The highest concentrations of Mn and As in vegetables (onion and pointed gourd, respectively), Cr and Cd in fruits (black berry and mango, respectively), and Pb in fish (catla) are recorded. Health risks associated with these heavy metals are evaluated due to dietary intake. Target hazard quotient (THQ) and hazard index (HI) are calculated to evaluate the non-carcinogenic health risk from individual and combined heavy metals. The THQ values for individual heavy metals are below 1, suggesting that people would not experience significant health risks if they ingest a single heavy metal from one kind of foodstuff (e.g.; vegetables). However, consumption of several of the foodstuffs could lead a potential health risk to human population since HI value is higher than 1. The relative contributions of vegetables, fishes, and fruits to HI are 49.44, 39.07, and 11.53 %, respectively. Also, the relative contributions of Pb, Cd, As, Mn, and Cr to HI are 51.81, 35.55, 11.73, 0.85, and 0.02 %, respectively. The estimation shows that the carcinogenic risk of arsenic exceeds the accepted risk level of 1 × 10-6. Thus, the carcinogenic risk of arsenic for consumers is a matter of concern. © 2012 Springer Science+Business Media B.V.

Mystus vittatus (Bloch, 1794), an indigenous small fish of Bangladesh, belongs to the family Bagridae, widely distributed in Asian countries including Bangladesh, India, Pakistan, Sri Lanka, Nepal and Myanmar. However, natural populations are seriously declining due to high fishing pressure, loss of habitats, aquatic pollution, natural disasters, reclamation of wetlands and excessive floodplain siltation and it is categorized as vulnerable species. This paper suggests the measures for the conservation of the remnant isolated population of M. vittatus in the waters of Asian countries. © The Author(s) 2014.

The recent report of the Intergovernmental Panel on Climate Change confirmed that there is overwhelming evidence that the global climate will severely affect human health. Climate change might have severe consequences on public health in Bangladesh, especially in light of the poor state of the country's public health infrastructure. A number of possible direct and indirect impacts of climate change on public health in Bangladesh have been identified in this article. Adaptive measures that should be taken to reduce the negative consequences of climate change on public health have also been discussed.

The effect of Zn substitution in the CuO 2 plane on the superconducting transition temperature, T c, was studied for the YBa 2(Cu 1-yZn y) 3O 7-δ compounds over a wide range of hole concentration, p, and Zn content (y). Zn induced rate of suppression of T c, dT c(p)/dy, was found to be strongly p-dependent and showed a monotonic variation with p, except in the region of the 60 K plateau where the charge/spin stripe correlations are believed to be at their strongest in Y123. The magnitude of dT c(p)/dy decreased significantly around this composition, implying that Zn suddenly became less effective in degrading T c. This is somewhat counterintuitive since static stripe ordering itself degrades superconducting order. We have discussed the possible scenarios that can give rise to such an anomalous dT c(p)/dy at the T c(δ) plateau. We have also looked at the p-dependent characteristic pseudogap energy scale, g(p), which shows a quasi-linear decrease with increasing p without any noticeable feature in the plateau region. Moreover, there is no appreciable effect of Zn content on the value of g(p). All these observations are indicative of a complex and possibly competing interplay among the superconducting, pseudogap, and stripe correlations in YBa 2(Cu 1-yZn y) 3O 7-δ compounds. © 2012 Elsevier B.V.

Starch is the main carbohydrate in human nutrition. Starch digestibility can vary from a rapid digestion to indigestibility. Therefore, postprandial glycaemic control in type 2 diabetics is of great interest in the context of worldwide health concerns. Although powerful synthetic inhibitors of starch digestive enzymes, such as acarbose, are available to control postprandial hyperglycemia, plant-based enzyme inhibitors are potentially safer. Natural enzyme inhibitors, such as wheat albumin, the Phaseolus vulgaris -amylase inhibitor, and several phenolic compounds, have the potential to serve as a remedy against hyperglycemia-induced chronic diseases. The inhibition of -amylase and -glucosidase is mediated by different phenolics found in varieties of raspberry. Maltase inhibitory activities of chebulagic acid and chebulinic acid from fruit of Terminalia chebula are comparable to that of acarbose. The Nepalese herb Pakhanbhed (Bergenia ciliata) phenolics, (-)-3-O- galloylepicatechin and (-)-3-O-galloylcatechin, showed effective inhibition against starch digesting enzymes. In separate studies, oral administration of starch and maltose with persimmon (Diospyros kaki) leaf tea proanthocyanidins [containing (-)-epigallocatechin-3-O-gallate] and black/bitter cumin (Centratherum anthelminticum) seed phenolics, respectively, resulted in a significant and dose-dependent decrease in the blood glucose level in Wistar rats. Co-application of phenolics with synthetic enzyme inhibitors may reduce the effective dose of synthetic inhibitors required in the regulation of starch digestion. Several phenolic compounds might be useful functional food components and could contribute to manage both hyperglycemia and proper cellular redox status. Human dose-selecting studies and well-controlled long-term human studies would help to optimize the beneficial effects of phenolic compounds. © 2013 Copyright Taylor and Francis Group, LLC.

Cellulose | Year: 2013

The structure of microbial cellulose (MC) produced by Acetobacter xylinum was studied in presence of Fluorescent Brightener, Direct Blue 1, 14, 15, 53, Direct Red 28, 75 and 79, as probe. X-ray diffraction pattern of the product showed that it was a crystalline complex of dye and cellulose. The product has the structure in which the monomolecular layer of the dye molecule is included between the cellulose sheets corresponding to the (110) planes of microbial cellulose. As a result of dye inclusion, d-spacing of lower angle plane (100) of products becomes 8. 0-8. 8 Å instead of 6. 1 Å of MC. The d-spacing for the higher angle plane must be (010) plane due to stronger van der Waals forces between the pyranose rings which reduced 5. 3 Å space of (110) plane of MC to 3. 9-4. 5 Å in the product. However, cellulose regenerated from FB, DR28 products was cellulose I and IV, respectively, and that from each DB1, 14, 15, 53, DR75 and 79 products was cellulose II. Solid state 13C NMR and deuteration-IR showed the product was non-crystalline which was contrasted to X-ray results. The regenerated celluloses were cellulose Iβ, IVI and II, respectively. Thus the structure of the product depends on the characteristics of dye which affects the conformation of cellulose at the nascent stage by the direct interaction with cellulose chains. The different regenerated celluloses as well as different fine structure in the same cellulose allomorph were produced depending mainly on number and position of the sulfonate groups in the dye. © 2013 The Author(s).

Antimalarial drugs (e.g. chloroquine and its close structural analogues) were developed primarily to treat malaria; however, they are beneficial for many dermatological, immunological, rheumatological and severe infectious diseases, for which they are used mostly today. Chloroquine and hydroxychloroquine, two of the most fascinating drugs developed in the last 50 years, are increasingly recognized for their effectiveness inmyriad non-malarial diseases. In advanced research, chloroquine and hydroxychloroquine have been shown to have various immunomodulatory and immunosuppressive effects, and currently have established roles in the management of rheumatic diseases, lupus erythematosus (different forms) and skin diseases, and in the treatment of different forms of cancer. Recently, chloroquine analogues have also been found to have metabolic, cardiovascular, antithrombotic and antineoplastic effects. This review is concerned with the lysosomotropic, anti-inflammatory and immunomodulatory mechanisms of chloroquine, hydroxychloroquine, quinacrine and related analogues, and the current evidence for both their beneficial effects and potential adverse manifestations in various diseases. © The Author 2015.

We investigate the Hawking radiation of Schwarzschild-de Sitter (SdS) black hole by massive particles tunneling method. We consider the spacetime background to be dynamical, incorporate the self-gravitation effect of the emitted particles and show that the tunneling rate is related to the change of Bekenstein-Hawking entropy and the derived emission spectrum deviates from the pure thermal spectrum when energy and angular momentum are conserved. Our result is also in accordance with Parikh and Wilczek's opinion and gives a correction to the Hawking radiation of SdS black hole. © 2012.

Methods: Different level of Al and P were added in two compartments in various combinations for separate root halves. Constrasting Al-tolerant (ET8) and Al-sensitive (ES8) wheat genotypes were used as a testing plant.Background and aims: My previous experimental findings suggested that phosphorus (P) enhances aluminium (Al) tolerance in both Al-tolerant and Al-sensitive wheat seedlings. However, the role of P in the amelioration of Al toxicity within plant tissue is still unclear. Therefore, a soil culture horizontal split-root system was used to quantify whether or not translocated P alleviates Al toxicity within the plant tissue.Conclusions: Result from this study confirm that addition of P to Al toxic acid soil played dual role like amelioration of Al-toxicity in soil and utilize P as nutrition for plant growth and development. Findings also attributed that added P was reduced by precipitation with added Al. However, evidence found that translocated P was not able to alleviate Al toxicity within plant tissue of both ES8 and ET8.Results: The limitation of root growth was independent to Al-toxicity in one root half. However, root proliferation occurred as a compensatory growth on the other root half that has no Al-toxicity. Where half of the roots were given 60 mg P/kg, plant did not translocated P in the other part of the root system that grown in Al toxic soil. When 40 mg P/kg were mixed with 60 mg AlCl3/kg within one root half combinations, root dry weight of both ET8 and ES8 increased markedly in that root half. In contrast, root dry weight of both ET8 and ES8 decreased noticeably only 60 mg AlCl3/kg treated root half. The shoot P and Al uptake in both ET8 and ES8 was lower in combined 40 mg P/kg and 60 mg AlCl3/kg addition as compared to other combination with same P and Al level. © 2014, Springer International Publishing Switzerland.
