Comprehensive characterization of tobacco-induced changes in enamel surface topography.

Introduction: Enamel translucency, essential for the aesthetic appeal of teeth, is primarily determined by its thickness, quality, and refractive index. Several factors, including age, genetics, diet, oral hygiene practices, fluoride exposure, and acidic challenges, can influence enamel translucency. Tobacco use, in particular, leads to significant alterations in enamel appearance by penetrating its micropores, causing yellowing and browning.

Exploring the frontiers of metal additive manufacturing in orthopaedic implant development.

This paper provides a thorough analysis of recent advancements and emerging trends in the integration of metal additive manufacturing (AM) within orthopedic implant development. With an emphasis on the use of various metals and alloys, including titanium, cobalt-chromium, and nickel-titanium, the review looks at their characteristics and how they relate to the creation of various orthopedic implants, such as spinal implants, hip and knee replacements, and cranial-facial reconstructions. The study highlights how metal additive manufacturing (AM) can revolutionize the field by enabling customized implant designs that take patient anatomical variances into account.

Enhanced diabetic retinopathy detection using U-shaped network and capsule network-driven deep learning.

Glaucoma, a severe eye disease leading to irreversible vision loss if untreated, remains a significant challenge in healthcare due to the complexity of its detection. Traditional methods rely on clinical examinations of fundus images, assessing features like optic cup and disc sizes, rim thickness, and other ocular deformities. Recent advancements in artificial intelligence have introduced new opportunities for enhancing glaucoma detection.

Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) in People Living With HIV Attending Centre of Excellence in HIV Care at a Tertiary Level Teaching Hospital in North India-A Pilot Study.

With the availability of free antiretroviral therapy (ART) across India, HIV in adults has become a chronic disease with prolonged survival. The emergence of various non-communicable diseases in these prolonged survivors is a cause of concern. Metabolic dysfunction-associated steatotic liver disease (MASLD) in adults with HIV infection in India has not been explored to date.
