Expression of Ki-67 and E-cadherin in patients with non-small cell lung cancer attending a tertiary care hospital

Background: E-cadherin and Ki-67 expressions may provide real-time insights into the tumor\u27s status and can be utilized as targeted therapeutics for lung cancer. We aimed to explore the expression of Ki-67 and E-cadherin in non-small cell lung cancer (NSCLC) patients and to identify their association with clinicopathological features. Methods: In this cross-sectional study, forty formalin-fixed paraffin-embedded (FFPE) NSCLC tissue blocks were identified from January to October 2022, based on hospital records from the Department of Pathology of National Institute of Diseases of the Chest and Hospital, Dhaka Medical College and Hospital. Samples were reevaluated for tissue quality, diagnosis, and exclusion-inclusion criteria. Finally, twenty-five samples were analyzed, and relevant clinicopathological data were collected from patients or authorized representatives. Ki-67 and E-cadherin expression were analyzed by immunohistochemistry and their relationships with each other. Results: Ki-67 expression was positive in 40% of the NSCLC tissue, and E-cadherin was negative in 40% of the NSCLC tissue. No statistically significant relation was found between the expressions of Ki-67 and E-cadherin. No statistically significant association was found in Ki-67 and E-cadherin expressions with clinicopathological characteristics except E-cadherin with comorbidity. Conclusion: Positive expression of Ki-67 and negative expression of E-cadherin was found in two-fifths of NSCLC tissues but not significant. Simultaneous estimated of Ki-67 and E-cadherin may contribute to the treatment planning and predict prognosis of the NSCLC patients

COMPARATIVE STUDY OF PROFESSIONALISM OF FUTURE MEDICAL PROFESSIONALS AMONG THREE PRIVATE MEDICAL COLLEGES OF BANGLADESH

Objectives: Medical professionalism forms the bridge between doctors and society. Conserving and maintaining professionalism is obligatory for physician curriculum. The objective of this study was to scrutinize and compare the professionalism of future medical professionals among different medical institutes. Methodology: It was a cross-sectional study conducted on 332 year-III and year-IV MBBS students of session 2012-2013 from three private medical colleges in Bangladesh. Data was collected using a mixed validated instrument containing items under fundamental elements of professionalism, measured by 5-points Likert scale giving a maximum score of 220. Results: Among 332 respondents, 44% were male, 56% female; Year-III respondents constituted 51% and Year-IV constituted 49%. Mean professionalism scores for male and female were 176.21 and 175.33, while for Year-III and Year-IV were 174.96 and 176.50 respectively. No significant differences observed between gender and year of study. However, significant differences were noticed between year-IV male students among three medical colleges. Majority (83%) students were imprecise of professionalism. Conclusions: Lack of focus is a worry for professionalism. Educators should focus on fundamental elements of professionalism.

Fermenting Feminism

"Fermenting Feminism brings together artists whose work responds to what it means to bring fermentation and feminism into the same critical space. These are works that approach fermentation through intersectional and trans-inclusive feminist frameworks, and works that approach feminisms through the metaphor and material practice of fermentation. As both a metaphor and a physical process, fermentation embodies bioavailability and accessibility, preservation and transformation, inter-species symbiosis and coevolution, biodiversity and futurity, harm reduction and care." -- p.

The impact of the COVID-19 pandemic on the education of medical, dental and non-medical healthcare professionals in Bangladesh : findings and connotation

Lockdown measures in response to the COVID-19 pandemic had an appreciable impact on the education of all medical, dental, and non-medical healthcare professional (HCP) students. These included the closure of universities necessitating a rapid move to e-learning and new approaches to practical’s. However initially, there was a lack of knowledge and expertise regarding e-learning approaches and the affordability of internet bundles and equipment. We initially con-ducted two pilot studies to assess such current challenges, replaced by a two-stage approach including a full investigation involving 32 private and public universities during the early stages of the pandemic followed by a later study assessing the current environment brought about by the forced changes. Top challenges at the start of the pandemic included a lack of familiarity with e-learning approaches, cost of the internet, lack of IT equipment and the quality of the classes. Universities offered support to staff and students to a varying degree to address identified challenges. Since then, e-learning approaches have widened the possibilities for teaching and learning at convenient times. However, challenges remain. In conclusion, there were considerable challenges at the start of them pandemic. Several key issues have been addressed with hybrid learning here to stay. Remaining challenges include a lack of ICT equipment. However, new innovations will continue

HEPATO-PROTECTIVE ROLE OF THE AQUEOUS AND N-HEXANE EXTRACTS OF NIGELLA SATIVA LINN. IN EXPERIMENTAL LIVER DAMAGE IN RATS

Objective: Liver disease is associated with the formation of oxygen derived free radicals. Reactive oxygen species (ROS) as well as nitrogen species are responsible for nuclear DNA fragmentation and cell death. Active principle of thymoquinone (TQ) of Nigella sativa acts as a scavenger of superoxide anion. Current study was conducted to evaluate the hepatoprotective effect of Nigella sativa on rats. Methods: The study was carried out at prime postgraduate medical University of Bangladesh. Liver damage and oxidative stress were evaluated by measuring serum alanine amino transferase (ALT), hepatic malondialdehyde (MDA) and hepatic Glutathione (GSH) levels. Aqueous extract of Nigella sativa and n-hexane extract of Nigella sativa were administered orally into two groups' of rats through intra-gastric tube for 28 days. Both the groups received paracetamol intraperitoneally on day 28th and were sacrificed on day 30th. Subsequently, the following parameters were studied: Serum ALT, hepatic MDA, and hepatic GSH. Results: Hepatic damage was evaluated by significant increases in serum ALT (p<0.001) and hepatic MDA (p<0.001) concentration with depleted hepatic GSH (p<0.001) in paracetamol treated group. Pre-treated with aqueous extract of Nigella sativa significantly reduced serum ALT (p<0.001) and hepatic MDA (p<0.001) levels and also significantly associated with the increase in hepatic GSH (p<0.01). Pretreatment with n-hexane extracts of Nigella sativa decreased serum ALT (p<0.001), hepatic MDA (p<0.001) and increased hepatic GSH (p<0.001). Conclusion: Hepatoprotective properties of Nigella sativa in liver damage of experimental rats by reducing oxidative stress is evident. Protection afforded by the n-hexane extract of Nigella Sativa in pre-treated group has also been validated. KEY WORDS: Hepatoprotective, Liver-damage, Nigella sativa Linn

Phylogenetic diversity and functional potential of the microbial communities along the Bay of Bengal coast

Abstract The Bay of Bengal, the world's largest bay, is bordered by populous countries and rich in resources like fisheries, oil, gas, and minerals, while also hosting diverse marine ecosystems such as coral reefs, mangroves, and seagrass beds; regrettably, its microbial diversity and ecological significance have received limited research attention. Here, we present amplicon (16S and 18S) profiling and shotgun metagenomics data regarding microbial communities from BoB’s eastern coast, viz., Saint Martin and Cox’s Bazar, Bangladesh. From the 16S barcoding data, Proteobacteria appeared to be the dominant phylum in both locations, with Alteromonas, Methylophaga, Anaerospora, Marivita, and Vibrio dominating in Cox’s Bazar and Pseudoalteromonas, Nautella, Marinomonas, Vibrio, and Alteromonas dominating the Saint Martin site. From the 18S barcoding data, Ochrophyta, Chlorophyta, and Protalveolata appeared among the most abundant eukaryotic divisions in both locations, with significantly higher abundance of Choanoflagellida, Florideophycidae, and Dinoflagellata in Cox’s Bazar. The shotgun sequencing data reveals that in both locations, Alteromonas is the most prevalent bacterial genus, closely paralleling the dominance observed in the metabarcoding data, with Methylophaga in Cox’s Bazar and Vibrio in Saint Martin. Functional annotations revealed that the microbial communities in these samples harbor genes for biofilm formation, quorum sensing, xenobiotics degradation, antimicrobial resistance, and a variety of other processes. Together, these results provide the first molecular insight into the functional and phylogenetic diversity of microbes along the BoB coast of Bangladesh. This baseline understanding of microbial community structure and functional potential will be critical for assessing impacts of climate change, pollution, and other anthropogenic disturbances on this ecologically and economically vital bay
