A Hospital based study of High Resolution Computed Tomography and Conventional Radiography for Evaluation of Pathologies of Temporal Bone [PDF]
Perspectives In Medical Research, 2020 Background: Many imaging modalities have been in use for the evaluation of temporal bone lesions. Plain X-rays are cost-effective however; they provide limited details and hence sometimes may result in an inaccurate diagnosis. With the advent of HRCT,

Aneurysms of the Temporal Bone
Ear, Nose & Throat Journal, 1993 Aneurysms of the internal carotid artery in the temporal bone are rare lesions which can present clinically as a growth in the middle ear cleft. Hemorrhage, occurring spontaneously or iatrogenically, is a primary concern. This study describes morphological and embryological characteristics of the internal carotid artery in relationship to the ...

Osteogenic Effects of Ion Released from Biodegradable Metallic Magnesium and Calcium Coating
Advanced Biology, EarlyView.This study explores how magnesium–calcium coatings on titanium promote osteogenesis by releasing ions and elevating pH during degradation. Using osteoblast‐like cells, the research demonstrates that both ion release and pH changes contribute to cell proliferation, differentiation, and mineralization, offering new insights into the design of bioactive ...

Functional Hydrogel for Modulating Lipid Droplets and Neuroinflammation in Head Injury
Advanced Functional Materials, EarlyView.After TBI, elevated cholesterol levels in activated microglia lead to the accumulation of cholesterol esters in lipid droplets, exacerbating neuroinflammation. A β‐cyclodextrin‐conjugated GelMA (βCD‐GelMA) hydrogel is developed to promotes cholesterol efflux and reduces LDL influx, thereby alleviating intracellular cholesterol and lipid droplet buildup.

Advanced Functional Materials, EarlyView.This study demonstrates that the dual delivery of BMP‐2/‐7 coding cmRNAs for bone healing is demonstrated as feasible, safe, and highly osteogenic. Compared to single BMP‐2 or BMP‐7 cmRNAs, the combination enhances the production of both mineral and organic components of the extracellular matrix when delivered using a collagen‐HA scaffold, supporting ...
