Exosome‐mimetic vesicle‐encapsulated multi‐responsive antibacterial hydrogel core‐shell microneedle patch promotes scarless healing of infected wounds

BMEMat, EarlyView.
The core‐shell microneedle patch VP@FNV‐CuO2‐MN was fabricated by encapsulating n‐CuO2 in a moderately crosslinked PVA/CMCS/Borax4 hydrogel shell and VP‐loaded fibroblast membrane nanovesicles (VP@FNV) in a highly crosslinked PVA/CMCS/Borax6 hydrogel core. Upon application to an infected wound, the acidic microenvironment triggers Fenton‐like reactions

Collagen orientation in periosteum and perichondrium is aligned with preferential directions of tissue growth

, 2008
A feedback mechanism between different tissues in a growing bone is thought to determine the bone's morphogenesis. Cartilage growth strains the surrounding tissues, eliciting alterations of its matrix, which in turn, creates anisotropic stresses, guiding

Creb5 coordinates synovial joint formation with the genesis of articular cartilage

Nature Communications, 2022
Zhang et al. show that the Creb5 transcription factor regulates the formation of synovial joints, directs the genesis of articular cartilage, and regulates the shape of the ends of long bones by blocking Wnt5a expression in the perichondrium.

Engineering an artificial trachea: Quantitative benchmarks and modular strategies for mechanics, epithelialization, and vascular integration

FlexMat, EarlyView.
In this work, we first examine the limitations of surgical repair and stenting, including migration, granulation, mucus plugging, and infection. We then translate these failures into engineering constraints involving geometry, mechanics, fixation, degradation, junctional stress, and remodeling.

COMPARATIVE STUDY BETWEEN FAT AND PERICHONDRIUM GRAFT MYRINGOPLASTY [PDF]

Zagazig University Medical Journal, 2014
Introduction: Longstanding tympanic membrane perforation may cause hearing loss and middle ear infection even if they are small in size. The purpose of myringoplasty is to repair such perforations and thus to improve hearing and eliminate the ...

Management of Auricular Hematoma With Bolster Versus Quilting: A Retrospective Cohort Study

The Laryngoscope, EarlyView.
This retrospective cohort study compared outcomes between bolster dressings and through‐and‐through mattress quilting sutures in the management of auricular hematoma in 43 patients. Recurrent hematoma occurred in 30% of the bolster group and 0% of the quilting group, with no significant differences in complications observed between the two groups ...

Approach to Surgical Repair of Nasal Septal Perforation

The Laryngoscope, EarlyView.
Nasal septal perforation repair remains technically demanding, with technique selection guided by perforation size, location, etiology, and patient risk factors. Contemporary evidence supports mucosal advancement flaps for small perforations (< 1 cm), bilateral advancement with interposition grafting or trilayer temporoparietal fascia–polydioxanone ...
