PurposeThis research aims to assess the consumers' intention to purchase organic foods for balanced physical and mental growth. It examines the decision-making process in buying organic products built on the extended Theory of Planned Behaviour (TPB). This study designed a model to show how Bangladeshi consumers wish to purchase organic food.Design/methodology/approachData were collected by means of a formal questionnaire from shoppers in different markets who buy organic and non-organic foods. Statistical analysis is done by applying partial least square-structural equation modelling (PLS-SEM).FindingsFindings refer that among the four antecedents called social norms (SN), personal attitude (ATT), perceived behaviour control (PBC) and health consciousness (HC), three (ATT, PBC and HC) have a significant influence on the intention to consume organic food in Bangladesh. The only cognitive variable called social norm (SN) has no statistically significant impact though it positively relates to the behavioural intention to purchase organic food.Research limitations/implicationsThe fitted model did not consider any moderating or mediating variable though there might be such effects regarding organic food purchase and consumption. The study includes a major portion of the respondents from less than Tk. 20,000 monthly income group, which is a price-sensitive group from Bangladesh perspective. Hence, this price sensitivity might have a slight influence on the results of the study.Practical implicationsThis study includes four variables as the predictors to describe consumers' intention to purchase organic food products in Bangladesh. Among the predictors, health consciousness or awareness is found to be most powerful. Though consciousness is the key, the awareness of Bangladeshi citizen regarding organic food is lower than in other parts of the world. Hence, the research model directs the policymakers to increase awareness through different social campaigns.Social implicationsUnder Vision 2040 of promoting sustainable development, the government of Bangladesh is trying to increase organic food consumption. Production and consumption of organic food will positively impact society since organic fertilizers are environmentally friendly and do not harm society. This research promotes a strategy formulation to ensure the consumption of organic foods for a positive social impact.Originality/valueThis study is a unique research to concentrate on the importance and factors influencing the consumption of organic foods in Bangladesh, a recently graduated developing country. Furthermore, it extended the Theory of Planned Behaviour (TPB) and proposed a new conceptual framework.
Objective. To study pain coping strategies in patients with hip and knee osteoarthritis (OA), and to assess the psychometric qualities of the French version of the Pain Coping Inventory (PCI). Methods. We conducted a national, cross-sectional survey in a primary care setting in France. A total of 1,811 general practitioners included 5,324 patients with hip and knee OA who completed several questionnaires, including the PCI, which assesses ability to cope with pain. Results. The records of 4,719 (86.4%) patients were analyzed (knee 2,781; hip 1,553; hip and knee 385). Supporting the structure of the original questionnaire, we found that the 33 PCI questionnaire items could be grouped into 3 domains defining active coping strategies and 3 defining passive coping strategies. Acceptable convergent validity was found for the PCI (Cronbach's alpha coefficient for each domain >0.68). Coping strategy scores were significantly higher in patients with both knee and hip involvement (mean ؎ SD 2.3 ؎ 0.4) than for patients with OA at 1 site (mean ؎ SD 2.1 ؎ 0.4), and in women compared with men (P < 0.001). The use of passive pain coping strategies increased with OA duration, and was greater in older and overweight patients, in patients with no current physical activity or major impairment, in retired and nonworking patients, and in patients who were not married, and to a lesser extent in patients with higher pain intensity. Compared with previous data, patients with OA demonstrated lower active and higher passive strategies than patients with rheumatoid arthritis and other chronic painful conditions. Conclusion. The PCI has good structural validity and is highly suitable for analyzing active and passive pain coping strategies in OA. In OA, active and passive coping strategies differ significantly as a function of age, body mass index, OA involvement, professional and marital status, sport activities, and OA duration, with pain intensity having a weaker effect.
Objective: Present study aims to investigate both qualitative and quantitative phytochemicals presence, antioxidant, thrombolytic, a-amylase and cytotoxic activity of a Bangladeshi plant Steudnera colocasiifolia K. Koch leaf ethanolic extract. Methods: Phytochemical screening was accomplished by using established methods. Thrombolytic assay was conducted through clot lysis method. Al pha amylase inhibition assay was made by modified enzyme inhibitory action and cytotoxi city was studied by brine shrimp lethality test. Data was analyzed by One Way Analysis of Variance (ANOVA) using statistical software Statisti cal Package for Social Science (SPSS, Version 22.0, IBM corporation, NY) followed by stu dent 't' test with GraphPad Prism Data Editor for Windows, Version 6.0 (GraphPad software Inc., San Diego, CA). Results: Primary screening shows the presence of ma jor metabolites such as alkaloid, flavonoid, tannin, saponins, steroid, quinone, cellulose and glycosides while the quantitative analysis elicits the presence of magnificent amount of fla vonoid (70.60 ± 0.23), proanthocyanidin (64.46 ± 0.58), flavonol (71.22 ± 0.07) and total an tioxidant (66.40 ± 0.26) in the extract. The thrombolytic effect of S. colocasiifolia was found to be 35.16% and this extract had good a-amylase inhibitory activity (IC 50 =2.16 ± 0.06 mg/ml) as compared to Acarbose. The extract was found to have a LC 50 value of 305.2 μg/ml in Brine shrimp lethality bioassay. Conclusion: Results demonstrate the Steudnera colocasiifolia has a very good prospect to be studied further for its extended antioxidative and a-amylase inhibi tory effects.
Purpose The purpose of this research is to assess the tax stakeholders’ intention towards the adoption of blockchain technology (BT) for a transparent and effective taxing system in Bangladesh. It examines the factors influencing the behavioural intention of the users to adopt BT with a blended model built on the technology acceptance model (TAM) and self-determination theory (SDT). This research develops a prescriptive model to demonstrate how the stakeholders are interested in adopting BT for the taxing system. Design/methodology/approach Data were obtained through a structured questionnaire from the stakeholders of the taxing system, including tax policymakers, tax commissioners, tax officers, lawyers, tax consultants and the taxpayers. Statistical analyses were performed using partial least square-structural equation modelling. Findings Results reveal that out of the two primary TAM antecedents known as usefulness (PU) and ease of use (PEU), PU has a significant influence on the BT adoption intention. The only cognitive variable called autonomous motivation picked from SDT has a positive and significant impact on BT adoption for tax purpose as well. Finally, trust is found to be another important determinant for explaining stakeholders’ intention to adopt BT for an efficient taxing system where transparency can be ensured. Research limitations/implications The proposed model does not include any moderator though there might be a moderating effect in this regard. The variation described in the behavioural intention to adopt BT by the predictors is half of the total possible variations. Hence, the inclusion of variables such as social influence and controlled motivation could be interesting. Practical implications This study is expected to provide valuable insights into policymaking for tax administrations to enhance the tax collection net and maintain transparency and efficiency in the taxing system. Social implications This research has social consequences for a recently graduated developing economy such as Bangladesh, where transparency and efficiency are a matter of question. Because BT adoption can assure a convenient and favourable environment for the taxpayers upholding the principles of taxation, it can play a significant role by ensuring social justice and equity through a transparent and effective taxing system. Originality/value This research is among the first few studies to address the issue of implementing a modern technology such as BT for an efficient taxing system from a developing country perspective. Furthermore, it combined TAM and SDT to propose a hybrid model for explaining behavioural intention to adopt an emerging technology such as blockchain, which is a new phenomenon.
Background Hopea Odorata, locally known as Telsur (Bangladesh), has some traditional uses as folk medicine. This study aims to investigate the antioxidant, antidiarrheal, hypoglycemic and thrombolytic activities of H. odorata leaf extracts as new therapeutic prospects predicting the activity of some of the isolated compounds of this plant.MethodsLeaves of Hopea odorata was extracted with pure methanol (MEHO), ethanol (EEHO) and water (AEHO). The extract was tested for antioxidant activity by using reducing power and H2O2 scavenging assay. Antidiarrheal effects were assayed by three standard methods of bioassay: Castor oil-induced diarrhea, Castor oil induced enteropooling and gastrointestinal transit test. Hypoglycemic effect was determined by normoglycemic model of mice. Thrombolytic activity was evaluated by clot lyses test for human and mice blood. In silico PASS prediction was applied for phytoconstituents namely Balanocarpol, Hopeaphenol and Ampelopsin H isolated from this plant. ResultAmong the all extracts, MEHO exhibited strong antioxidant activity in both reducing power and H2O2 scavenging assay. Phenol content of MEHO was 297.22 ± 0.78 mg/g and flavonol content was 91.53 ± 1.82 mg/g. All the experiment of extracts at dose of 200 and 400 mg/kg and the standard drug loperamide (5 mg/kg) showed significant (p < 0.001) inhibition against castor oil induced diarrhea and castor oil induced enteropooling in mice. There were also significant (p < 0.01) reduction in gastrointestinal motility in the charcoal meal test. Leaf extract showed no significant (P < 0.01) decrease of blood glucose compared to Glibenclamide in normoglycemic mice. Using an in vitro thrombolytic model, MEHO showed the highest and significant clot lysis of human and mice blood compared to Streptokinase. PASS predicted the wide range of antioxidant, free radical scavenger, Nitric oxide scavenger, cardioprotectant, hepatoprotectant, thrombolytic, fibrinolytic, antibacterial, antifungal, anticarcinogenic, anthelmintic and anti-inflammatory activity of examined phytoconstituents.ConclusionThese findings suggest that the plant may be a potential source of new antidiarrheal, thrombolytic and antioxidative agents but it is found to have no antidiabetic capability. PASS prediction matched with present study for the extracts. Further study needs to identify the PASS predicted biological actions of the phytoconstituents.Electronic supplementary materialThe online version of this article (doi:10.1186/s12906-016-1461-x) contains supplementary material, which is available to authorized users.
Background: Fatigue is a frequent and disabling symptom of multiple sclerosis (MS) often associated with impaired quality of life (QoL) in patients. Teriflunomide is a once-daily oral immunomodulator used for the treatment of relapsing remitting forms of MS. However, its effect on fatigue is not well known in real life practice. We evaluated the impact of teriflunomide on fatigue in patients with relapsing remitting MS (RRMS) after 2 years of treatment in the real-world Teri-FAST study. Methods: Teri-FAST was a 2-year, prospective, observational study conducted in France in RRMS patients treated with teriflunomide 14 mg. Fatigue was assessed using the French version of the modified fatigue impact scale (EMIF-SEP). The primary endpoint was the change from baseline in EMIF-SEP score after 2 years of treatment. Secondary endpoints included evaluation of depression (Beck Depression Inventory [BDI]), health-related QoL (Two-Life Scale TLS-QoL 10), self-reported physical activity, and adverse events. Results: 210 eligible patients were included in the study with a mean age of 45.4 years and a mean ± SD Expanded Disability Status Scale score of 1.76 ± 1.43 at baseline. About half (52.4%) of patients had no previous treatment for MS. In the 163 patients who completed at least 1 follow-up visit, the mean change in EMIF-SEP score at Year 2 was -1.54 (95% CI: -4.02, 0.94) indicating that fatigue remained stable. Similarly, there were no changes in depression level and QoL after 2 years of treatment. Physical activity slightly improved with 57% of patients reporting being physically active after 2 years as compared to 46% at baseline. The safety profile of teriflunomide was consistent with that seen during clinical development, and compliance with treatment was high. Conclusion: Fatigue scores remained stable in RRMS patients treated with teriflunomide 14 mg over 2 years in real-life setting. Teriflunomide did not negatively impact depression or QoL.
Nimorazole belongs to the imidazole‐based family of antibiotics to fight against anaerobic bacteria. Moreover, nimorazole is now in Phase 3 clinical trial in Europe for potential use as a hypoxia radiosensitizer for treatment of head and neck cancers. We envision the use of [15N3]nimorazole as a theragnostic hypoxia contrast agent that can be potentially deployed in the next‐generation MRI‐LINAC systems. Herein, we report the first steps to create long‐lasting (for tens of minutes) hyperpolarized state on three 15N sites of [15N3]nimorazole with T1 of up to ca. 6 minutes. The nuclear spin polarization was boosted by ca. 67000‐fold at 1.4 T (corresponding to P15N of 3.2 %) by 15N−15N spin‐relayed SABRE‐SHEATH hyperpolarization technique, relying on simultaneous exchange of [15N3]nimorazole and parahydrogen on polarization transfer Ir‐IMes catalyst. The presented results pave the way to efficient spin‐relayed SABRE‐SHEATH hyperpolarization of a wide range of imidazole‐based antibiotics and chemotherapeutics.
Owing to the lack of research in emerging Asian nations, this research aimed to unearth the determinants of blockchain acceptance for supply chain financing by a Bangladeshi financing company called IPDC. Centred on a technology acceptance framework called UTAUT (unified theory of acceptance and use of technology) and open innovation research, an expanded model with a mediating variable is developed for this study. This research work employs the deductive inference method in conjunction with the positivism paradigm. A structural questionnaire was used to gather data, which were then processed through Smart-PLS (partial least square) for SEM (structural equation modeling). The survey includes all the people who are directly or indirectly involved in the supply chain financing platform of IPDC. The study consists of seven direct hypotheses and one mediating hypothesis. The results show that all the direct hypotheses except the impact of social influence on the behavioural intention to use (BINTU) blockchain are significant. The mediating hypothesis indicating the role of BINTU in the relationship between facilitating conditions (FCON) and the actual use of blockchain is also supported. FCON and BINTU together explain 88.7% variation in blockchain use behaviour for supply chain financing. The research advances past findings by employing an expanded UTAUT framework and validating observations with the other relevant studies throughout the world.
