Appendiceal Abscess Revealed by Ureteral Stenosis and Hydronephrosis

Asian Journal of Surgery, 2007
Acute appendicitis presenting with ureteral stenosis and hydronephrosis is very rare. Here, we report the case of a patient who had complicated acute appendicitis with perforation and abscess resulting in right pyeloureteral dilation.

Bone mesenchymal stem cells based on matric hydrogels attenuate intervertebral disc degeneration by suppressing oxidative stress-induced ferroptosis

Scientific Reports
Intervertebral disc degeneration (IVDD) and its attendant lower back pain are a major medical challenge. Ferroptosis has become a new target for the treatment of IVDD. Mesenchymal stem cells (MSCs) are a promising regenerative therapy for IVDD.

Enzyme‐Regulated Extended Swelling of Hydrogels for Dehiscence‐Less Tissue Expansions

Advanced Functional Materials, EarlyView.
An interpenetrating hydrogel network with swelling under regulation by enzymatic degradation (INSURED) is fabricated to avoid dehiscence. INSURED remains structurally intact post‐implantation, while HYAL injection enables control over the onset and rate of swelling.

Minimally Invasive Surgery in Gynecology

, 2022
The first laparoscopic procedure was performed by 1901 by Georg Kelling in dogs while the first laparoscopic procedure in humans was performed by Hans Chrisitan Jacobaeus in 1910. Minimally invasive surgery offers multiple advantages over conventional laparotomy and is associated with reduced estimated blood loss, a lower incidence of complications and

Light‐Responsive Enzyme‐Loaded Nanoparticles for Tunable Adhesion and Mechanical Wound Contraction

Advanced Functional Materials, EarlyView.
This study presents a photoactivatable enzyme‐loaded mesoporous nanoparticle system (MPDA_PaTy) that enables light‐triggered tunable tissue adhesion and facilitates mechanical wound contraction. Controlled enzymatic crosslinking at tissue or hydrogel interfaces allows on‐demand adhesion.

3D Differentiation of Bone‐Marrow Derived Mesenchymal Stromal Cells into the Keratocyte Lineage for Corneal Bioprinting

Advanced Healthcare Materials, EarlyView.
This study introduces a novel differentiation protocol for generating corneal stromal keratocyte‐like cells using drop‐on‐demand bioprinting and a collagen‐based hydrogel. The bioprinted constructs maintained a stable dome shape over 21 days while exhibiting upregulated CSK markers postdifferentiation.
