An improved extrinsic monolingual plagiarism detection approach of the Bengali text

Plagiarism is an act of literature fraud, which is presenting others’ work or ideas without giving credit to the original work. All published and unpublished written documents are under the cover of this definition. Plagiarism, which increased significantly over the last few years, is a concerning issue for students, academicians, and professionals. Due to this, there are several plagiarism detection tools or software available to detect plagiarism in different languages. Unfortunately, negligible work has been done and no plagiarism detection software available in the Bengali language where Bengali is one of the most spoken languages in the world. In this paper, we have proposed a plagiarism detection tool for the Bengali language that mainly focuses on the educational and newspaper domain. We have collected 82 textbooks from the National Curriculum of Textbooks (NCTB), Bangladesh, scrapped all articles from 12 reputed newspapers and compiled our corpus with more than 10 million sentences. The proposed method on Bengali text corpus shows an accuracy rate of 97.31

Parliamentary Election and Political Violence in Bangladesh

Politics of Bangladesh has been criminalized over the last four decades resulting multi-level political violence. Political violence is particularly high during the parliamentary election period. This study analyses the nature, causes, and immediate fatalities of political violence during parliamentary election in Bangladesh. Secondary research methods have been used to conduct this study. Data were collected using structured checklist technique analyzing the newspaper contents. This study has revealed that incidents of violence in the month of parliamentary election as well as before and after the month of election are higher than other months. People also become more victim of violence in the month of parliamentary election, before and after the month of parliamentary election than other months. This study has found that the main causes of political violence are strike, blockade, internal and external conflict between political parties, political conflicts, political revenge and establishing political supremacy over a certain area. This study also found that police responses to the incidents of political violence is very low. This rationale of the study implies on that the descriptive findings of the study that can be used to understand the issues and formulate policy to prevent political violence as well as to improve political environment in Bangladesh encouraging the democratic culture to fulfill their goals avoiding the means of violence and conflict.

Effect of variety and nutrient sources on growth and yield of broccoli in southern belt of Bangladesh

Ongoing use of synthetic fertilizers affects soil structure. Organic manures can serve as an alternative to synthetic fertilizers. The study evaluated performance of five different types of nutrient sources (T0 =control, T1 = Urea @ 250 kg/ha, TSP @ 150 kg/ha, MoP @ 200 kg/ha, T2 = Cowdung @ 25 t/ha, T3 = Vermi compost @ 5 t/ha, T4 = fermented plant juice @ 500 ml/ha and T5 =Liquid fertilizer (Flora: consists of 20% nitrobenzene) @ 200 ml/ha) on growth and yield of broccoli, cvs. “V1=Known You” and “V2=Early Green”. Yield and yield contributing parameters such as plant height, number of leaves per plant, leaves fresh weight, length of stem, stem diameter, stem fresh weight, days taken for primary curd initiation, curd diameter, fresh weight of primary curd, no. of secondary curd per plant, fresh weight of secondary curd and yield per plot as well as hectare were measured in this experiment. In case of variety, the highest yield/plot 5.83kg and yield/ha 20.23 tons were recorded from “Early green”. Considering the nutrient factor, the highest curd weight (290.4g) per plant and yield/plot (5.01kg) were found in fermented plant juice nutrient sources. The highest benefit cost ratio BCR (3.21:1) was found in V2T4, among all other treatment combinations in respect of net return (Tk. 228934.97/ha) through the use of  fermented plant juice. Therefore, it can be concluded that fermented plant juice @ 500 ml/hacan be used to improve vegetative growth, and yield quality and quantity, and the broccoli cv. “Early Green” appears to be the best of the cultivars tested

Raphanus sativus ameliorates atherogeneic lipid profiles in hypercholesterolemic rats and hypercholesterolemia-associated peroxidative liver damage

Objective: Raphanus sativus is a hugely used edible root vegetable. We investigated whether the feeding of the Raphanus sativus hot water extract (RSE) ameliorates atherogenic lipid profile and oxidative stress in hypercholesterolemia. Methods: After feeding of the RSE to hypercholesterolemic rats for 6 weeks, the levels of plasma and hepatic total cholesterol (TC), triglyceride (TG), and plasma high density lipoprotein-cholesterol (HDL-C) and fecal TC levels were studied. The effects of RSE on the hepatic enzymes, namely alanine aminotransferase (ALT), aspartate aminotransferase (AST) and alkaline phosphatase (ALP), the levels of lipid peroxide (LPO) and liver histology were also evaluated. Results: Hypercholesterolemia increased the levels of TC and TG in the plasma and livers. The levels of ALT, AST and ALP in plasma and LPO in the liver also increased. The dietary RSE, however, significantly ameliorated the above atherogenic lipids and liver enzymes. The RSE significantly reduced the levels of LPO in the liver, suggesting an in vivo protection against of oxidative stress. The RSE also inhibited the in vitro Fenton’s reagent-induced oxidative stress, thus corroborating the in vivo anti-LPO actions of RSE. The levels of hepatic LPO were positively correlated with plasma AST (r=0.76; P <0.05) and ALT (r=0.43; P<0.05) levels. Histologically, the livers of the RSE-fed hypercholesterolemic rats exhibited lesser fatty droplets and reduced inflammatory cells. Conclusion: Finally, R. sativus extract lowers the cardiovascular disease risk factors under hypercholesterolemic situation by increasing the plasma/hepatic clearance of cholesterol and improving the hypercholesterolemia-induced oxidative damage of hepatic tissues

Sense and Manner of WASH and Their Coalition With Disease and Nutritional Status of Under-five Children in Rural Bangladesh: A Cross-Sectional Study

This study aimed to assess the knowledge and practice of caregivers and their relationship to the disease and nutritional status of children under 5 years of age in rural areas of Sylhet, Bangladesh. A total of 110 households with at least a child aged 6 to 59 months were selected by simple random method from 10 rural communities of three Upazila of Sylhet from September 2019 to February 2020. Descriptive statistics were used to assess the “Water Access, Sanitation, and Hygiene” (WASH) knowledge and practice, and multivariate chi-square analyses were performed to assess associations among diseases and nutritional status with WASH following a structured questionnaire. The study found a significant association between WASH with childhood disease and nutritional status, and 65% of children were found to be in a diseased state and 35% of children were found in a no exposure of disease state within the last 6 months. The findings sketched that mother with poor WASH knowledge and practice was at greater risk for disease outbreaks, disease frequency, and duration. The highest incidence of diarrhea was 17% in children aged 12 to 23 months. A significant effect of WASH was also found in children’s nutritional status, which was reflected in the ratio of stunted, underweight, and wasted children. Integrated convergent work focusing on providing clean water within the household, stopping open defecation, promoting handwashing, behavior change, and poverty alleviation is needed to improve the situation. Health, nutrition, and livelihood programs should be uninterrupted, and mothers or caregivers should be encouraged to participate in these programs

Isolation of multidrug-resistant Escherichia coli and Salmonella spp. from sulfonamide-treated diarrheic calves

Background and Aim: The bovine industry is threatened by one of the most serious and deadly enteric diseases, calf diarrhea, particularly in developing nations like Bangladesh. In this context, bacterial resistance to antimicrobial drugs and its detrimental consequences have become a critical public health issue that is difficult to address globally. This study aimed to isolate and identify Escherichia coli and Salmonella spp. with their antibiogram and antibiotic resistance gene detection from sulfonamide-treated diarrheic calves. Materials and Methods: Twelve diarrheic calves suffering from calf diarrhea in a dairy farm were selected and a total of 36 fecal samples were aseptically collected directly from rectum before, during, and at the end of treatment for each calf to determine the total viable count, total E. coli count and total Salmonella count. A polymerase chain reaction was used for the specific detection of E. coli and Salmonella genus targeting fliC and invA genes, respectively. Antibiotic sensitivity test of the isolated E. coli and Salmonella spp. were performed by the disk diffusion method for eight commonly used antibiotics. Results: A total of 36 E. coli (100%) and 12 Salmonella spp. (33%) were isolated from the samples and were confirmed by polymerase chain reaction. Total viable count was found to be ranged from 35 × 107 to 99 × 1010 colony-forming unit (CFU)/g fecal sample before starting sulfonamide treatment, 34 × 105 to 25 × 1010 CFU/g during treatment with sulfonamide, and 48 × 103 to 69 × 1010 CFU/g immediately after completion of sulfonamide treatment. Total E. coli count was found to be ranged from 4 × 104 to 36 × 1010 CFU/g, 24 × 104 to 23 × 108 CFU/g, and 13 × 104 to 85 × 1010 CFU/g, whereas total Salmonella count was found to be ranged from 16 × 106 to 18.5 × 1011 CFU/g, 15 × 104 to 44 × 107 CFU/g, and 13.2 × 105 to 21 × 1010 CFU/g fecal sample before starting sulfonamide treatment, during treatment with sulfonamide immediately after completion of sulfonamide treatment, respectively. The in vitro antibiotic sensitivity test showed that all the E. coli and Salmonella spp. isolated from diarrheic calves (100%) contained multidrug-resistant (MDR) phenotypes. Escherichia coli isolates were found 100% resistant to amoxicillin (AMX), cefuroxime, cephalexin (CN), erythromycin (ERY), and tetracycline (TET); whereas 94.4%, 86.1%, and 77.8% isolates were resistant to doxycycline (DOX), moxifloxacin (MOF), and gentamycin (GEN), respectively. In case of Salmonella isolates, all were found 100% resistant to AMX, CN, and ERY; whereas 91.7% of resistance was observed for DOX, MOF, cefuroxime, GEN, and TET. Based on the molecular screening of the antibiotic resistance genes, tetA gene was present in 83.3% of the isolated E. coli and 75% of the isolated Salmonella strains, whereas 83.3% E. coli and 79.2% Salmonella isolates contained blaTEM gene. Conclusion: These findings suggest that MDR E. coli and Salmonella spp. might be responsible for calf scouring, which is challenging to treat with antibiotics or sulfonamide drugs alone. Therefore, it is important to check the antibiotic sensitivity pattern to select a suitable antibiotic for the treatment of calf scoring. A suitable antibiotic or combination of an antibiotic and sulfonamide could be effective against E. coli and Salmonella spp. responsible for calf scouring

The global burden of cancer attributable to risk factors, 2010-19 : a systematic analysis for the Global Burden of Disease Study 2019

Background Understanding the magnitude of cancer burden attributable to potentially modifiable risk factors is crucial for development of effective prevention and mitigation strategies. We analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019 to inform cancer control planning efforts globally. Methods The GBD 2019 comparative risk assessment framework was used to estimate cancer burden attributable to behavioural, environmental and occupational, and metabolic risk factors. A total of 82 risk-outcome pairs were included on the basis of the World Cancer Research Fund criteria. Estimated cancer deaths and disability-adjusted life-years (DALYs) in 2019 and change in these measures between 2010 and 2019 are presented. Findings Globally, in 2019, the risk factors included in this analysis accounted for 4.45 million (95% uncertainty interval 4.01-4.94) deaths and 105 million (95.0-116) DALYs for both sexes combined, representing 44.4% (41.3-48.4) of all cancer deaths and 42.0% (39.1-45.6) of all DALYs. There were 2.88 million (2.60-3.18) risk-attributable cancer deaths in males (50.6% [47.8-54.1] of all male cancer deaths) and 1.58 million (1.36-1.84) risk-attributable cancer deaths in females (36.3% [32.5-41.3] of all female cancer deaths). The leading risk factors at the most detailed level globally for risk-attributable cancer deaths and DALYs in 2019 for both sexes combined were smoking, followed by alcohol use and high BMI. Risk-attributable cancer burden varied by world region and Socio-demographic Index (SDI), with smoking, unsafe sex, and alcohol use being the three leading risk factors for risk-attributable cancer DALYs in low SDI locations in 2019, whereas DALYs in high SDI locations mirrored the top three global risk factor rankings. From 2010 to 2019, global risk-attributable cancer deaths increased by 20.4% (12.6-28.4) and DALYs by 16.8% (8.8-25.0), with the greatest percentage increase in metabolic risks (34.7% [27.9-42.8] and 33.3% [25.8-42.0]). Interpretation The leading risk factors contributing to global cancer burden in 2019 were behavioural, whereas metabolic risk factors saw the largest increases between 2010 and 2019. Reducing exposure to these modifiable risk factors would decrease cancer mortality and DALY rates worldwide, and policies should be tailored appropriately to local cancer risk factor burden.

The global burden of adolescent and young adult cancer in 2019 : a systematic analysis for the Global Burden of Disease Study 2019

Background In estimating the global burden of cancer, adolescents and young adults with cancer are often overlooked, despite being a distinct subgroup with unique epidemiology, clinical care needs, and societal impact. Comprehensive estimates of the global cancer burden in adolescents and young adults (aged 15-39 years) are lacking. To address this gap, we analysed results from the Global Burden of Diseases, Injuries, and Risk Factors Study (GBD) 2019, with a focus on the outcome of disability-adjusted life-years (DALYs), to inform global cancer control measures in adolescents and young adults. Methods Using the GBD 2019 methodology, international mortality data were collected from vital registration systems, verbal autopsies, and population-based cancer registry inputs modelled with mortality-to-incidence ratios (MIRs). Incidence was computed with mortality estimates and corresponding MIRs. Prevalence estimates were calculated using modelled survival and multiplied by disability weights to obtain years lived with disability (YLDs). Years of life lost (YLLs) were calculated as age-specific cancer deaths multiplied by the standard life expectancy at the age of death. The main outcome was DALYs (the sum of YLLs and YLDs). Estimates were presented globally and by Socio-demographic Index (SDI) quintiles (countries ranked and divided into five equal SDI groups), and all estimates were presented with corresponding 95% uncertainty intervals (UIs). For this analysis, we used the age range of 15-39 years to define adolescents and young adults. Findings There were 1.19 million (95% UI 1.11-1.28) incident cancer cases and 396 000 (370 000-425 000) deaths due to cancer among people aged 15-39 years worldwide in 2019. The highest age-standardised incidence rates occurred in high SDI (59.6 [54.5-65.7] per 100 000 person-years) and high-middle SDI countries (53.2 [48.8-57.9] per 100 000 person-years), while the highest age-standardised mortality rates were in low-middle SDI (14.2 [12.9-15.6] per 100 000 person-years) and middle SDI (13.6 [12.6-14.8] per 100 000 person-years) countries. In 2019, adolescent and young adult cancers contributed 23.5 million (21.9-25.2) DALYs to the global burden of disease, of which 2.7% (1.9-3.6) came from YLDs and 97.3% (96.4-98.1) from YLLs. Cancer was the fourth leading cause of death and tenth leading cause of DALYs in adolescents and young adults globally. Interpretation Adolescent and young adult cancers contributed substantially to the overall adolescent and young adult disease burden globally in 2019. These results provide new insights into the distribution and magnitude of the adolescent and young adult cancer burden around the world. With notable differences observed across SDI settings, these estimates can inform global and country-level cancer control efforts. Copyright (C) 2021 The Author(s).

Prevalence of helminth and protozoan infections in pet birds of Chattogram, Bangladesh

Abstract Background Parasitic diseases such as helminths and protozoa are considered one of the major impediments in the rearing of pet birds. The current study was undertaken to determine the prevalence of helminths and protozoal infections in different captive pet birds in Chattogram metropolitan area, Bangladesh. Methods A total of 549 pooled faecal and 311 individual blood samples were collected from different species of pet birds during June 2019 to May 2020. The faecal samples were examined following routine microscopic tests to identify the eggs and oocysts of helminths and protozoan parasites, respectively. Polymerase chain reaction (PCR) was performed to determine the haemoprotozoan parasites. Results The prevalence of helminth infestations in pet birds was 8.01% (95% confidence interval [CI]: 5.88–10.61), where infestation caused by nematodes was the highest (7.47%, CI: 5.41–10). Ascaridia and Capillaria spp. infestations were the commonest helminths recorded in different groups of pet birds. The overall prevalence of intestinal protozoal infections was 11.11% (CI: 8.61–14.04) in pet birds. The most commonly occurring protozoal infections were Eimeria spp. (7.83%, CI: 5.73–10.41) followed by Isospora spp. (2.91%, CI: 1.67–4.69). The overall prevalence of haemoprotozoan parasites was 2.25% (CI: 0.91–4.58) in different groups of pet birds. The highest prevalence was recorded in Plasmodium spp. (1.29%, CI: 0.35–3.26) followed by Leucocytozoon and Haemoproteus spp. Conclusions The data generated in this study are the first of its type, which would be beneficial to the veterinary practice, aviculturists, pet bird owners and breeders in Bangladesh to respond appropriately for the prevention and control of the disease

Assessing the impacts of zeolite on water quality, growth performance, heavy metal content and health condition of farmed tilapia (Oreochromis niloticus)

The rapid expansion and intensification of tilapia (Oreochromis niloticus) aquaculture in Bangladesh results in an increasing tendency of administering more pharmaceuticals in fish health management. Hence, with the aim of investigating the effects of zeolite (a water and sediment treatment compound) on water quality, growth performance, hematology, gut microbial content, and heavy metal content of Oreochromis niloticus, an experiment was performed for 126 days in six experimental earthen ponds (each pond size is one decimal). The stocking density was 300 fry/decimal. Zeolite was applied directly into the water in treatment ponds at a rate of 200 g/decimal during pond preparation and 100 g/decimal/15 days intervals during the culture period as recommended by the manufacturing company. The results indicated that zeolite had a significant effect (p < 0.05) on all growth indices assessed in all three experimental stages (0–42 days, 43–84 days, 85–126 days) in treatment ponds compared to control ones, except condition factor (CF) at the first stage. Hematological results implied that the application of zeolite in treatment pond water had no significant effect on the red blood cell (RBC) and white blood cell (WBC) of experimental fish blood compared to the control. However, a significant effect on the blood glucose level and total viable count (TVC) of the experimental fish gut was observed due to the addition of zeolite in the treatment ponds. Zeolite supplementation in treatment pond water significantly reduced the concentrations of different heavy metals in pond sediment, water and fish flesh compared to the control. Therefore, zeolite could be recommended for administration in aquaculture. Further research is required to find out whether a higher or lower dose of zeolite improves the water quality, growth performance and health condition, and decreases the heavy metal content of fish or not
