With the advent of globalization, postsecondary education is considered a very significant part for any country's socio-economic development. Higher education in Bangladesh is in a state of flux while responding to the challenges of globalization and the privatization policies of the government in line with the neo-liberal economy have resulted in progressive growth of private universities in Bangladesh. The purpose of this study is to explore the impact of socioeconomic status on selecting postsecondary institution in Bangladesh. Survey method with a semi-structured questionnaire is used to explore the consequences and the result reveals that socioeconomic status of the students has been playing an important role on selecting post-secondary institutions in Bangladesh. Consequently, competent recommendations are proposed to improve the situation in institutional and policy levels.  Article visualizations

Impact of pre-sowing treatment on seed germination and seedlings growth attributes of Calamus longisetus Griff. at nursery and field conditions

The paper describes the germination behaviour of Calamus longisetus Griff. seeds under three different pre-sowing treatments and seedlings growth performance in nursery and field condition. Whole fruits, seeds with pulp and cleaned seeds were sown in germination trays filled with soils mixed with decomposed cowdung at a ratio of 3:1. The growth performance of the seedlings were determined by transferring the young seedlings (having 2 – 3 leaves) from germination bed to the polybags filled with soil mix followed by outplanting (at 1-year old) in the field. Germination percentage was significantly (p ≤0.001) enhanced by the pre-sowing treatment where the highest germination percentage was in cleaned seeds followed by the seeds with pulp and lowest in whole fruits. The survival percentage was over 91% in the field after one year and the average height 126.2 cm after two years of planting. Clean seeds for nursery raising and one-year old seedlings for outplanting were found suitable for raising successful plantations for the species

Gibberellic acid (GA3) affects growth and development of some selected kenaf (Hibiscus cannabinus L.) cultivars

Kenaf (Hibiscus cannabinus L.), is a potential alternative of natural wood fibers for biocomposite and pulp and paper industry. However, the average fiber length of kenaf is usually shorter than the critical length to be used for high quality biocomposite materials. Increasing fiber length and quality can diversify its application in fiber based industries. Gibberellic acid (GA3) is an important plant growth regulator that is actively involved in cell elongation and other important physiological functions in plant growth, development and flowering. To investigate the effects of gibberellin on growth, morphology, and fiber quality, some selected cultivars of kenaf plants were treated with aqueous solution of varying concentrations of GA3. The effects on vegetative and reproductive growth were evaluated weekly for sixteen consecutive weeks and fiber morphology after harvesting at 18th week. Gibberellin treatment significantly reduced the vegetative growth in terms of stem diameter, leaf number, and leaf size but stimulated fiber elongation, resulted in a tall and slender plant with curled leaves. Gibberellin treatment also impaired reproductive growth by inhibiting floral initiation and development in all treated plants whereas the control plants were in its seed harvesting stage. This study provided novel insights into the effects of GA3 in regulating vegetative and reproductive growth of kenaf as well as improving its fiber properties

Enhancing seed germination and seedling growth attributes of a medicinal tree species Terminalia chebula through depulping of fruits and soaking the seeds in water

Terminalia chebula (Gaertn.) Retz. is an important medicinal tree species in the Asian countries. Large scale planting program for the species is often difficult due to its limited seed germination capacity and longer germination period in the natural conditions. This study describes various pre-sowing treatments attributed to the seed germination and seedling growth of T. chebula. A total of 1200 fruits were subjected to various treatments of which 600 were depulped by rotting the fleshy pulp in water while rests were kept intact and dried followed by their storage in airtight containers until setting up for the experiments. The effects of depulping and soaking period (0, 24, 48 and 72h) on seed germination and seedling growth performance were explored. The fastest seed germination and highest germination percentage (73.8%) was observed in depulped seeds soaked in cold water for 48 h followed by 72 h and delayed germination with lowest percentage was in intact fruits without treatment. Growth parameters including shoot length, root length, total height, leaf number, leaf area, collar diameter, dry mass and vigor index were also maximum and significantly higher in the same treatment compared to others. Considering the practicability of the nursery raising technique for the species, the best treatment option obtained in this study was depulping the fruits and soaking the seeds in cold water for 48h which could be useful for large scale plantation programs. Introduction Medicinal plants play vital roles in healing various diseases throughout the world since time immemorial. Medicinal plants are now being used by Unani and Ayurvedic practitioners as well as by the common people to heal ailments at home. Plants with medicinal properties can also provide raw materials for downstream processing operations in the pharmaceutical industries

Determination of pond water quality for aquaculture and ecosystem management

Fish is the main source of animal protein for the common people of Bangladesh. About 37% of the inland fishes are obtained from the closed water fish culture where ponds play vital roles in the production system. The present study was carried out to determine the water quality (physico-chemical and biological factors) of five uncultivated or under cultivated ponds in the Chittagong University campus, Bangladesh, for aquaculture and ecosystem management. Temperature, pH, EC, BOD, COD, TSS, turbidity, NO2-, PO4 -, free CO2, CO3 -, HCO3-, Cl-, total viable bacterial count and total coliform were determined. Isolation and identification of Escherichia coli and Salmonella sp. from the water samples were performed to investigate the antibiotic sensitivity. The minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC) against ciprofloxacin was also investigated. The findings reveal that there was no significant difference in temperature (19°C to 20°C), pH (6.7 to 7.4), electrical conductivity and Cl- values in the water among the ponds and that was within the range of the requirements for the fish cultivation. Both turbidity and total dissolved solids was highest in the uncultivated botanical garden pond 2 (BGP2). BOD, COD, NO2- , PO 4-2, HCO3-, and free CO2 concentration was beyond the permissible limits for aquaculture. Total viable count and total coliform ranged from 1.3 × 10 4 to 6.6 × 10 5 cfu ml-1 and from 0.0205×10 2 to 1.10×10 2 ml-1 respectively, among the ponds where both these parameters were highest in the naturally polluted BGP2. Most of the isolated E. coli and Salmonella sp. were sensitive but few showed resistance against the antibiotics, especially in BGP1, where fishes were cultivated commercially

Evaluation of Loopamp™ Leishmania Detection Kit and Leishmania Antigen ELISA for Post-Elimination Detection and Management of Visceral Leishmaniasis in Bangladesh

With reduced prevalence of visceral leishmaniasis (VL) in the Indian subcontinent (ISC), direct and field deployable diagnostic tests are needed to implement an effective diagnostic and surveillance algorithm for post-elimination VL control. In this regard, here we investigated the diagnostic efficacies of a loop-mediated isothermal amplification (LAMP) assay (Loopamp™ Leishmania Detection Kit, Eiken Chemical CO., Ltd, Japan), a real-time quantitative PCR assay (qPCR) and the Leishmania antigen ELISA (CLIN-TECH, UK) with different sampling techniques and evaluated their prospect to incorporate into post-elimination VL control strategies. Eighty clinically and rK39 rapid diagnostic test confirmed VL cases and 80 endemic healthy controls were enrolled in the study. Peripheral blood and dried blood spots (DBS) were collected from all the participants at the time of diagnosis. DNA was extracted from whole blood (WB) and DBS via silica columns (QIAGEN) and boil & spin (B&S) methods and tested with qPCR and Loopamp. Urine was collected from all participants at the time of diagnosis and was directly subjected to the Leishmania antigen ELISA. 41 patients were followed up and urine samples were collected at day 30 and day 180 after treatment and ELISA was performed. The sensitivities of the Loopamp-WB(B&S) and Loopamp-WB(QIA) were 96.2% (95% CI 89·43-99·22) and 95% (95% CI 87·69-98·62) respectively. The sensitivity of Loopamp- DBS(QIA) was 85% (95% CI 75·26- 92·00). The sensitivities of the qPCR-WB(QIA) and qPCR-DBS(QIA) were 93.8% (95% CI 86·01-97·94) and 72.5% (95% CI 61·38-81·90) respectively. The specificity of all molecular assays was 100%. The sensitivity and specificity of the Leishmania antigen ELISA were 97.5% (95% CI 91·47-99·70) and 91.95% (95% CI 84·12-96·70) respectively. The Leishmania antigen ELISA depicted clinical cure at day 180 in all the followed-up cases. Efficacy and sustainability identify the Loopamp-WB(B&S) and the Leishmania antigen ELISA as promising and minimally invasive VL diagnostic tools to support VL diagnostic and surveillance activities respectively in the post-elimination era

Exploring barriers to accessing healthcare services for older indigenous people in the Chittagong Hill Tract, Bangladesh

We aim to investigate the obstacles faced by elderly indigenous individuals in the Chittagong Hill Tracts, Bangladesh when accessing healthcare services. A qualitative research approach was utilized, and data collection was carried out in three distinct regions of the aforementioned area. A total of 30 in-depth, semi-structured interviews and participant observations were conducted to achieve the research objectives. Thematic analysis utilizing both a deductive and inductive approach was employed to analyze the data. The Granheim method and Nvivo-12 software were utilized to process, analyze and code the data. The study's findings indicate that a lack of knowledge about healthcare needs, geographical barriers, poor financial conditions, higher cost of medical services, scarcity of hospitals nearby and communication barriers all contribute to inadequate access to healthcare services. By recognizing the factors that impede access to healthcare services in this region, this study offers valuable insight for policymakers and healthcare providers on how to enhance healthcare services for the indigenous population, especially the elderly. Furthermore, the government can adopt a more efficient approach to include these elderly individuals in various social safety net programs
