Bangladeshi students of English programs encounter some barriers in their attempt to develop academic writing skill at undergraduate level. The majority of the students who study in English programs in Bangladesh receive their primary and secondary schooling in the instruction medium of Bangla, while a few percent in English medium and English version instructions. Testing and assessment in English studies predominantly focuses on academic writing skill and many students cut a sorry figure in formative and summative assessments in the very first semester due to poor writing competence. This study examined two issues: the difficulties that Bangladeshi undergraduates of English studies confront while developing academic writing skill, and the ways to develop L2 English writing skill. Participants of this study were 6 students studying English in different Bangladeshi universities and 3 English teachers who were teaching at tertiary level. Data collection tools were composition writing samples on a selected topic for undergraduates and a semi-structured interview schedule for teachers. Results indicated that poor grammatical competence and brainstorming skill, insufficient vocabulary, inadequate knowledge of mechanics and writing style, and mother tongue interference were the major barriers that Bangladeshi undergraduates of English studies frequently faced while writing in English.

Artificial intelligence (AI) has rapidly transformed numerous industries, including medicine, with radiography standing to benefit significantly from its capabilities. AI enhances diagnostic accuracy, reduces errors, and improves patient care by leveraging large datasets from digital radiographs commonly used in medical and dental practices. Despite these advantages, the impact of AI on image acquisition and radiographer workflows remains underexplored in radiography literature. This review aims to evaluate the effects of AI on radiographic practices, address regulatory challenges, and explore its integration into educational frameworks for radiologists and radiographers. It highlights AI's role in automating tasks, enhancing diagnostic precision, and improving clinical decision-making. A systematic literature search was conducted using PubMed and Google Scholar up to December 2024, with terms including "artificial intelligence," "machine learning," "deep learning," "radiography," and "diagnostic imaging." Seventy-seven peer-reviewed articles and conference papers focusing on AI applications in digital dental radiography were analyzed to extract data on AI methodologies and their potential applications. The findings reveal that AI-powered solutions enhance efficiency in complex imaging tasks, such as lesion identification and triage in mammography, and real-time assessments in cross-sectional imaging, reducing the need for re-scans and increasing patient throughput. However, widespread adoption faces obstacles related to ethical and legal concerns, including data privacy, algorithmic bias, and the need for transparency. While AI demonstrates significant potential to automate workflows, improve diagnostic accuracy, and optimize patient care in radiography, challenges related to human oversight, professional adaptation, and regulatory compliance must be addressed. Further research is needed to fully understand AI’s impact on radiography and to maximize its clinical utility.

Secondary metabolites, a type of bioactive molecule with many functions, are abundant in Araucaria Heterophylla. The secondary metabolites flavonoids, phanolic acid, and tannin have been found to have anti-inflammatory, antiviral, antibacterial, antioxidant, and anticancer properties. The present study was conducted to analyze the phytochemical and determine the total flavonoid, tannin, phenolic content of Araucaria Heterophylla leaves extract using two different solvents (methanol and dichloromethane) using UV-Vis spectrophotometric. The plant was identified by NHB (ID No: DACB 48435) and prepared the methanolic extract to estimate the total content of tannin, phenolic & flavonoid in Araucaria Heterophylla. Folin-ciocaltu method was used for the investigation of total phenolic and tannin content. The A. heterophylla leaf methanolic and dichloromethane extract had remarkable antioxidant effects due to its high flavonoid and phenolic content. This standardised bioactive ingredient could be used in many phytopharmaceutical preparations

Multiple myeloma (MM) is a hematologic malignancy characterized by the uncontrolled proliferation of plasma cells, leading to complications such as bone lesions, renal dysfunction, and immune suppression. Over the past three decades, its incidence has risen significantly, attributed to factors such as aging populations and improved diagnostic methods. Treatment strategies have evolved considerably, transitioning from alkylating agents and high-dose chemotherapy to targeted therapies, including proteasome inhibitors (PIs) and immunomodulatory drugs (IMiDs). Bortezomib, a first-in-class PI, has revolutionized MM management by inhibiting proteasome activity, thereby inducing apoptosis in malignant plasma cells. This review evaluates the efficacy, safety, and clinical applications of bortezomib, both as monotherapy and in combination with dexamethasone, IMiDs, and conventional chemotherapies. Key clinical trials, such as VISTA and SUMMIT, demonstrate its superiority over traditional regimens, improving response rates and survival outcomes. However, its use is associated with adverse effects, including peripheral neuropathy, hematologic toxicities, and gastrointestinal disturbances, necessitating dose modifications and supportive care. Emerging combinations with monoclonal antibodies and novel agents further enhance therapeutic potential, though optimal sequencing remains under investigation. Systematic literature search was performed using PubMed and Cochrane to identify relevant studies on the applications of bortezomib. The search was inclusive of all publications up to May 2025, without restriction by publication year, to ensure a thorough review of research on bortezomib. Studies focusing on multiple myeloma (MM) and the efficacy of bortezomib were prioritized. A broad set of keywords was employed reflecting the diverse applications of bortezomib in MM treatment. The search strategy was designed to capture a wide range of relevant studies. By synthesizing evidence from 77 studies, this review highlights bortezomib’s pivotal role in MM treatment while addressing challenges in toxicity management. Future research should focus on refining combination strategies and minimizing side effects to maximize long-term patient outcomes.

Nipah virus (NiV) is an emerging zoonotic pathogen with significant pandemic potential. Large outbreaks, such as in Malaysia, required the culling of over one million pigs to control transmission. However, the epidemiology of NiV among animal hosts, including pigs, horses, and bats, remains incompletely understood. NiV infection primarily affects the respiratory and nervous systems, causing severe pneumonia, vasculitis, and meningitis, while encephalitis may be mild or infrequent in some cases. This systematic review summarizes current evidence on NiV mutational variation, pathogenesis, treatment strategies, and vaccine development up to 2022. Data were collected from major databases, including PubMed, PMC, and Cochrane Library. Due to limited therapeutic options, NiV management relies mainly on supportive care, as no approved vaccines or specific antiviral treatments are available for humans or livestock. Preventive strategies focus on reducing zoonotic transmission, particularly by minimizing contact between livestock and bat-contaminated food sources, and improving farm management practices. Early detection and continuous surveillance of high-risk populations and animal reservoirs are essential for outbreak control. Current vaccine research targets viral antigens using subunit and vector-based approaches. Overall, further studies are urgently needed to develop effective vaccines and antiviral therapies for NiV infection.
