    Abstract: The purpose of the study was to develop and optimize floating bioadhesive gastroretentive drug delivery system (GRDDS) exhibiting a unique combination of floatation and bioadhesion to prolong residence in the stomach, using hydrochlorothiazide (HCTZ) as a model drug. Formulated matrix tablets were prepared by direct compression method with two different rate controlling polymer HPMC K4M and Carbopol 971. The formulated tablets were evaluated for physical characterization, floating lag time, swelling index and drug content uniformity. The drug release study was carried out in 0.1N HCl as the medium (pH 1.2) for 8 hours using USP type II dissolution apparatus and investigated the effects of polymers on the drug release profile. In vitro buoyancy study results found to be 1033 sec and 〉 8 h, floating lag time and total floating time respectively. Simulated drug release pattern in different kinetic models of Korsmeyer-Peppas release suggests that the mechanism controlling of the drug release from all formulations was the anomalous non-Fickian or anomalous release. Polymer with lower viscosity (HMPC K4M) was found to be beneficial than higher viscosity polymer (Carbopol 971) in improving the release properties of gastric floating drug delivery system. Incorporation of Carbopol in formulation also helped in maintaining buoyancy of system with desirable drug release. Further study is necessary in case of in vitro- in vivo relationship, but this study will ready to lend a hand to future scientists working in this field to successfully exploit the potential of this drug delivery system for the advantage of mankind.Dhaka Univ.

    Abstract: Random amplified polymorphic DNA (RAPD) markers were employed for characterization, assessment of genetic variation and inferring relationships among six variants of Canna indica L. A total of 198 RAPD bands ranging from 200 bp to 3 kbp were generated by all the six variants. Among them, most of the bands were found to be polymorphic, four band were unique of which two bands (OPA022000 and OPA043000) were observed in the variant 2 (small red) and the other two (OPA013000 and OPA053000) were noticed in the variant 4 (orange), and the remaining bands were found to be monomorphic. The pair-wise genetic distance was determined among the six variants that ranged from 0.1446 to 0.6554. A dendogram was constructed based on the RAPD profiling to infer the relationship among the six variants of C. indica that resulted in two major clusters: the first one contained two variants, viz. variant 1 (local red) and variant 2 (small red), while the second cluster composed of the remaining four variants. The results as revealed from the RAPD analysis were found congruent with those of morphological and anatomical investigation of the species. Bangladesh J. Plant Taxon. 28(1): 75-81, 2021 (June)

    Abstract: The present study was carried out for the isolation and molecular detection of duck plague virus (DPV) for the development of inactivated vaccine seed from the local outbreaks. A total of 12 suspected dead duck samples were collected from commercial farms and local market at Sunamganj, Netrokona and Mymensingh districts. Then, the samples were processed and prepared inocula were inoculated into 9-12 days old duck embryonated eggs. In duck embryonated eggs, several passages (3-4) were performed before infection into DEF cell culture. Presence of viral DNA was confirmed by PCR using the primer for DNA polymerase gene. After PCR confirmation, virus cultured in DEF cell was used for the preparation of formalin (0.12%) inactivated and oil based adjuvanted vaccine and was experimentally injected to 18 ducklings and 5 were kept as control. TCID50 of the selected virus for vaccine preparation was 108.70/ml. The mean passive haemagglutination assay (PHA) titre of sera of samples at 0 days, 7 days and 14 days post vaccination were 4.0±0, 14.22±1.78 and 44.44±4.4, respectively, which indicated significant (p 〈 0.01) increase of antibody titre. Embryonated duck eggs and DEF cell culture are effective for virus isolation and on the basis of PHA test, it could also be suggested that the experimentally developed DP vaccine can be used successfully for the prevention of DP in Bangladesh.

    Abstract: Adolescence is a critical period characterized by rapid physical, psychological, and social development and growth. In Bangladesh, high rates of undernutrition persist among adolescent females living in low‐income households. Prevalence of adolescent marriage and pregnancy is extremely high, with almost half of Bangladeshi women giving birth by 18 years of age. Qualitative research was carried out from April to June 2017 to examine individual, social, and environmental factors influencing eating behaviours of female adolescents between 15 and 19 years of age living in low‐income families in urban and rural settings in Bangladesh. Methods included freelisting exercises (33), key informant interviews (11), in‐depth interviews (24), direct observations (16), and focus group discussions (12). Findings show that household food insecurity necessitates adjustments in meal food quality and frequency. Gender norms prescribe that females receive small meal portions and make sacrifices in food consumption so that male family members can eat more. Work and school schedules cause long breaks between meal consumption, restricting food intake of adolescent females for extended periods. Gender discrimination and its manifestations likely amplify susceptibility to psychological stresses in adolescent females. An inferior social position makes adolescent females living in food insecure households vulnerable to undernutrition, with factors affecting food deprivation increasing as they approach childbearing. Policies to increase age of marriage and reduce adolescent pregnancy must continue. Programmes must ensure that school‐going adolescents eat adequately during the school day. Prolonging school education and strengthening the economic viability of women should alter cultural expectations regarding marriage age and normative female roles.

    Abstract: Avipox is a viral disease of fowl and pigeon which is characterized by proliferative and nodular lesions in the feather-free parts of the skin or fibro-necrotic and proliferating part in the mouth, esophagus, and mucous membrane of the upper respiratory tract. This investigation was carried out with an aim to isolate and molecular detection of Fowl pox virus (FPV) and Pigeon pox virus (PPV) for development of live attenuated vaccine seeds from the local virus isolates. In this study, nodular lesions were collected from seven pigeons and four chickens from different areas of Mymensingh in Bangladesh which were affected by pox. Viral inoculums were prepared and DNA materials were extracted for PCR-based identification of P4b genes. Detection of virus was confirmed by PCR following propagation into 9-11 days old embryonated chicken egg (ECE) and also chicken embryo fibroblast (CEF) cell culture All the field samples were found positive for FPV and PPV by PCRR. These field isolates were propagated and attenuated in duck embryo through CAM route and duck embryo fibroblast (DEF) cell culture for the  development of live attenuated vaccine seeds. Attenuation of both FPV and PPV were successful in duck embryo through CAM route and duck embryo fibroblast (DEF) cell culture after serial six passages. Attenuation of the virus was confirmed by inoculation into experimental birds. Inoculation of attenuated FPV and PPV in chicken and pigeon respectively exhibited no pox lesions whereas control chicken and pigeon inoculated with field isolates develop nodular lesions. Both FPV and PPV were confirmed from both groups of birds by PCR. These attenuated local isolates of FPV and PPV could be used as  potential vaccine candidates for the prevention and control of fowl pox and pigeon pox in Bangladesh. J. Bangladesh Agril.

    Abstract: The present study explores detailed morphological and anatomical features of six variants of Canna indica L. Noticeable variations have been recorded in the morphology of six variants of C. indica especially on the basis of their different colours of leaves, flowers, staminodes and fruits. Root, stem and leaf anatomy of C. indica revealed little variation among the variants employed in the study. Phloem is 5-6 layered in the variant 2 (small red), 4-5 layered in the variant 4 (orange), and 3-4 layered in the remaining variants. The variant 4 (orange) can be distinguished from other five variants anatomically, by presence of 5-7 layers of schlerenchymatous tissue, and morphologically by its green pseudostem, ovate to obovate leaves, orange flowers, green bracts with maroon edges and orange-red staminodes. However, based on morphological and anatomical discrepancies the variants of Canna indica cannot be assigned to discrete taxonomic variety.

    Abstract: Sclerotium oryzae causing sheath rot of rice, is one of the most important pathogen causing heavy crop losses in all the major rice growing areas of the world, including Bangladesh. The growth and reproduction of this soil borne pathogen depends on growing media and abiotic factors. Therefore, to evaluate the effect of different culture media and pH on mycelial radial growth of S. oryzae, the experiment was conducted in the Plant Pathology Laboratory of Agrotechnology Discipline, Khulna University, Khulna, Bangladesh. Performance of different media, carbon source and nitrogen source on radial mycelial growth was differed significantly. The maximum mycelial radial growth was observed on rice stem agar medium (70.40 mm) and minimum mycelial radial growth was recorded on cornmeal agar medium (50.60 mm). Considering carbon source, the maximum radial mycelial growth was found in glucose (66.40 mm) amended medium and no statistical differences were observed among sucrose, starch and Czapek dox agar containing medium. Based on nitrogen source, maximum radial mycelial growth was found in peptone medium (69.40 mm) but no statistical differences were exposed between Potassium nitrate (KNO3) and Sodium nitrate (NaNO3). pH- 6 played a vital role in radial mycelial growth (73.75 mm) of S. oryzae.

    In: Journal of Banking & Financial Services, University of Dhaka, Vol. 13, No. 01 ( 2022)
    Abstract: Islamic Insurance has recently been one of the most prominent Islamic financial services among the Muslim as well as non-Muslim community in the world. In Bangladesh, the service is also getting popularity to the people for the special features like risk-bearing by all of the participants, interest-free investment of funds etc. Considering the rapid growth of Islamic financial products worldwide and inadequate research on the limited reach of these services, this study aims to explore the factors affecting the customers’ purchase intention of Islamic insurance services in Bangladesh. The cross-sectional study has been conducted based on the Structural Equation Modeling (SEM) on the data collected through a self-administered questionnaire from 392 respondents. According to the study, it is revealed that compatibility, religiosity, customer awareness, reliability and trust have significant positive impact on customers’ purchase intention towards Takaful services in Bangladesh. The study result will help the service providers to look into the factors while tailoring their products and services. The policy makers should also know about the determinants so that they can formulate policies that promote the growth of the takaful industry and increase access to these products for consumers.
