OSSICULAR STATUS IN CHOLESTEATOMA : A DEPARTMENTAL EXPERIENCE IN A STATE MEDICAL COLLEGE OF WESTBENGAL.

Bengal Journal of Otolaryngology and Head Neck Surgery, 2015
Introduction: Chronic otitis media is a long standing infection of part or whole of middle ear cleft. Its active squamosal variant (cholesteatoma) is most dangerous due to its bone eroding property.

Ultrasound‐Activated Piezoelectric Neuroimmune Hydrogel Orchestrates Neurogenesis‐Macrophage Crosstalk in Diabetic Wound Healing

Advanced Science, EarlyView.
In this work, we design an ultrasound‐activated piezoelectric hydrogel platform (AOEF@AP5+US) that reprograms neurogenesis‐macrophage crosstalk as an integrated strategy to overcome the intertwined barriers of chronic inflammation, peripheral neuropathy, and impaired regeneration in diabetic wounds.

A CROSS-SECTIONAL STUDY ON TECHNIQUE FOR REMOVAL OF EAR OSSICLES: A DIAGONAL CORONAL SECTION METHOD. [PDF]

Background The retrieval of intact ear ossicles (malleus, incus, and stapes) from the temporal bone is crucial for anatomical studies, implant design, and educational purposes.

Characterizing bone density pattern and porosity in the human ossicular chain using synchrotron microtomography

Scientific Reports
The auditory ossicles amplify and transmit sound from the environment to the inner ear. The distribution of bone mineral density is crucial for the proper functioning of sound transmission as the ossicles are suspended in an air-filled chamber.

Genetic Ablation and Multi‐Omics Profiling Reveal CEP55 as a Key Driver of Tumorigenesis in Diverse Cancer Models

Advanced Science, EarlyView.
Genetic ablation of Cep55 in Pten‐deficient mouse models delays tumorigenesis. Integrated multi‐omics analyses (proteomics, phosphoproteomics, and spatial transcriptomics) reveal that CEP55 regulates oncogenic signaling (RAS/ERK, PI3K/AKT), integrin/FAK‐mediated adhesion, extracellular matrix (ECM) remodeling, and endocytosis.

Dual Lineages of Langerhans Cells Cooperate to Restore the Immune Barrier after Skin Injury

Advanced Science, EarlyView.
After skin injury, the epidermal immune barrier is rebuilt by two sources of Langerhans cells. Resident Langerhans cells first move into the wound during re‐epithelialization, guided by CXCR2 signaling. Later, recruited monocytes become long‐lived Langerhans cells.

Fzd7 Restrains Pink1‐Dependent Mitophagy in Suture Stem Cells to Maintain Cranial Suture Patency

Advanced Science, EarlyView.
How suture stem cells fail to preserve cranial suture patency remains incompletely understood. Integrated single‐cell and high‐resolution spatial transcriptomic analyses identify reduced Fzd7 expression in Prrx1+ suture stem cells as an early feature of craniosynostosis.

Automated segmentation of the middle ear ossicles and tympanic cavity based on a deep-learning model

Informatics in Medicine Unlocked
Background: Prior to middle ear surgery, it is desirable to get concise information about the anatomy of the middle ear ossicles and the tympanic cavity in order to analyze the topographical conditions and identify anatomical impairments.
