So far, one of the major obstacles to the development of special purpose MRI imaging apparatus has been the lack of a magnetic technology that could cater to the need for a light, compact and efficient magnet, capable of providing the required field uniformity at a reasonable cost. Today, recent advances in magnet design permit attaining, with the use solely of ferrite, low-cost, small-scale scanners, which can open up new areas of application of MRI, in both medical and industrial fields. A novel apparatus (ARTOSCAN) is described and some examples of applications in different fields are shown. The apparatus has been designed specifically for the imaging of extremities, but possible applications on the industrial side are numerous and not yet all identified. Such a device could be used, for example, in the agricultural, food, and oil industries, where some of the needs for nondestructive quality-control devices could be fulfilled. Some tests have been performed that demonstrate the potential of the apparatus in the study of rock properties, of the drying process of pasta and wood, and to display flaws that could be present in ceramic materials before firing.

Indian Council of Medical Research-National Institute for Implementation Research on Non-Communicable Diseases, Jodhpur, 342005, India.
Background: Silicosis remains a major occupational health challenge in India. This review systematically examines the prevalence, risk factors, regional differences, and diagnostic tools specific to India's high-risk industries. Additionally, it assesses policy gaps and offers insights from diverse clinical and qualitative studies, aiming to inform targeted public health interventions and support the development of effective occupational health policies.

Background: Substantial out-of-pocket (OOP) expenditures push a large portion of the population below the poverty line, especially those residing in rural areas having low incomes. Individuals from economically disadvantaged states in India incur higher healthcare costs for hospitalization in public health centers than do those from more developed states. Economically poorer households in states such as Bihar and Odisha face significantly higher OOP expenditures for hospitalization in public health centers than do those in economically developed states such as Tamil Nadu.

Background: To develop and test the performance of a fully automated system for classifying renal tumor subtypes via deep machine learning for automated segmentation and classification.
Materials And Methods: The model was developed using computed tomography (CT) images of pathologically proven renal tumors collected from a prospective cohort at a medical center between March 2016 and December 2020. A total of 561 renal tumors were included: 233 clear cell renal cell carcinomas (RCCs), 82 papillary RCCs, 74 chromophobe RCCs, and 172 angiomyolipomas.
Optimization of the intron sequences combined with the CMV promoter increases recombinant protein expression in CHO cells.

To meet the requirements of the biopharmaceutical industry, improving the yield of recombination therapeutic protein (RTP) from Chinese hamster ovary (CHO) cells is necessary. The human cytomegalovirus (CMV) promoter is widely used for RTP expression in CHO cells. To further improve RTP production, we truncated the human CMV intron and further evaluated the effect of four synthetic introns, including ctEF-1α first, EF-1α first, chimeric, and β-globin introns combined with the CMV promoter on recombinant expression levels in transient and stably recombinant CHO cells.

AI decision support systems can assist clinicians in planning adaptive treatment strategies that can dynamically react to individuals' cancer progression for effective personalized care. However, AI's imperfections can lead to suboptimal therapeutics if clinicians over or under rely on AI. To investigate such collaborative decision-making process, we conducted a Human-AI interaction study on response-adaptive radiotherapy for non-small cell lung cancer and hepatocellular carcinoma.
