Identification of Common Dysregulated Genes in COVID-19 and Hypersensitivity Pneumonitis: A Systems Biology and Machine Learning Approach.

A comprehensive knowledge on systems biology of severe acute respiratory syndrome coronavirus 2 is crucial for differential diagnosis of COVID-19. Interestingly, the radiological and pathological features of COVID-19 mimic that of hypersensitivity pneumonitis (HP), another pulmonary fibrotic phenotype. This motivated us to explore the overlapping pathophysiology of COVID-19 and HP, if any, and using a systems biology approach. Two datasets were obtained from the Gene Expression Omnibus database (GSE147507 and GSE150910) and common differentially expressed genes (DEGs) for both diseases identified. Fourteen common DEGs, significantly altered in both diseases, were found to be implicated in complement activation and growth factor activity. A total of five microRNAs (hsa-miR-1-3p, hsa-miR-20a-5p, hsa-miR-107, hsa-miR-16-5p, and hsa-miR-34b-5p) and five transcription factors (KLF6, ZBTB7A, ELF1, NFIL3, and ZBT33) exhibited highest interaction with these common genes. Next, C3, CFB, MMP-9, and IL1A were identified as common hub genes for both COVID-19 and HP. Finally, these top-ranked genes (hub genes) were evaluated using random forest classifier to discriminate between the disease and control group (coronavirus disease 2019 [COVID-19] vs. controls, and HP vs. controls). This supervised machine learning approach demonstrated 100% and 87.6% accuracy in differentiating COVID-19 from controls, and HP from controls, respectively. These findings provide new molecular leads that inform COVID-19 and HP diagnostics and therapeutics research and innovation.

BEHAVIORAL PATTERN OF INFORMATION SEEKING USERS OF NATIONAL LIBRARY, KOLKATA

A library is an open system which in turn belongs to a subsystem of the education system, whose functions are dependent on the community concerned. The National Library plays a vital role in creating human resources and their development in our country. It is a life-long process in the appreciation of the achievement of humanity in knowledge and culture. It also helps in the replenishment of people's spirit by providing books for relaxation and pleasure, with assistance to the students. It performs a significant task in a developing country like India. The progress of a nation mainly depends on education, which provides to its citizens either through formal or non-formal means. In present study the behavioural pattern like their frequency of visit and dependence on the public library has been discussed with special reference to the National Library of India. The paper also explores the information seeking behaviour such as their purpose of visit, materials accessed during their visit to the National Library. The main objective of this study is to examine the services provided by National Library of India to its esteemed users.
