Versatility and Outcomes of ‘Mumbai Technique’ of Stacked Cartilage Grafts in Indian Rhinoplasty

open access: yesIndian Journal of Plastic Surgery
Background Augmentation rhinoplasty requires graft with substantial volume. In cases where patient is reluctant to use costal cartilage, this can be done using septum and conchal cartilage graft. Using the technique of “stacked cartilage graft”

Increased nasal tip projection with “pseudo-flaps” using excess lateral cephalic alar cartilage [PDF]

open access: yesRevista Brasileira de Cirurgia Plástica, 2019
Introduction: An increased nasal tip projection is sometimes necessary to achieve an appropriate proportion between nasal tip and dorsum. Numerous techniques and tactics have been described for this purpose using cartilaginous grafts obtained from the ...

Ultra‐Tiny Gelatin Nanoparticles‐Assisted 3D Stem Cell Spheroids for Engineering Tissue Regeneration

open access: yesAdvanced Healthcare Materials, EarlyView.
GNPs effectively guide the formation of structurally compact and functionally enhanced stem cell spheroids. This GNP‐assisted 3D culture system improves cell–cell and cell‐ECM interactions, leading to superior viability and complexity. Time‐dependent regenerative potential is demonstrated in both bone and skin defects, positioning GNP‐spheroids as a ...

Repair of sheep articular cartilage defects with a rabbit costal perichondrial graft [PDF]

open access: yesActa Orthopaedica Scandinavica, 1991
A xenograft of costal rabbit perichondrium was transplanted to an articular cartilage defect in a sheep knee. After 12 weeks, cartilage was formed with increased calcification of the basal layer and a mean of 74 percent collagen type II. The synovium did not show any infiltration, indicating the absence of any immunologic reaction.

Hierarchically MOF‐Based Porous Monolith Composites for Atmospheric Water Harvesting

open access: yesAdvanced Materials, EarlyView.
This review explores the design of hierarchical porous materials for atmospheric water harvesting, focusing on metal‐organic frameworks (MOFs) and porous monoliths. Emphasis is placed on integrating MOF nanoscale porosity with the microscale channels of monolithic scaffolds to enhance sorption‐desorption performance.

Age-related difficulty in post-intubation tracheal stenosis reconstruction: a comparative analysis of CO2-laser, resection and anastomosis, and costal cartilage grafting techniques

open access: yesThe Egyptian Journal of Otolaryngology, 2022
Background Costal cartilage graft (CCG) sustains primary donor material for laryngotracheal reconstruction in patients with post-intubation tracheal stenosis (PITS). But, the elasticity and viability of CCG decrease elderly.

Harnessing Photo‐Energy Conversion in Nanomaterials for Precision Theranostics

open access: yesAdvanced Materials, EarlyView.
Harnessing photo‐energy conversion in nanomaterials enables precision theranostics through light‐driven mechanisms such as photoluminescence, photothermal, photoelectric, photoacoustic, photo‐triggered surface‐enhanced Raman scattering (SERS), and photodynamic processes. This review explores six fundamental principles of photo‐energy conversion, recent
