Objective: To demonstrate the watertight seal created by the new wide-angle Landers trunkless temporary keratoprosthesis (T-TKP).
Methods: In 20 enucleated, porcine eyes, a 7.5-mm trephination was made, followed by capsulorrhexis and lensectomy. The T-TKP was sutured securely onto each eye. Testing the watertight seal at an intraocular pressure of 100 mm Hg was performed before and after pars plana vitrectomy.
Results: In all 20 eyes, the T-TKP maintained its watertight seal at an intraocular pressure of 100 mm Hg before and after vitrectomy.
Conclusion: The Landers T-TKP is a reusable device that provides a clear view and watertight eye in the presence of corneal trephinations up to 7.5 mm in diameter. Because of its unique trunkless design, as demonstrated in the laboratory, the T-TKP should allow the surgeon greater flexibility than previous models in cases of ocular trauma.

The velar chord and dynamic integration of the gular valve in crocodylians.
Anat Rec (Hoboken)
December 2024
Department of Anatomy, Kirksville College of Osteopathic Medicine, AT Still University, Kirksville, Missouri, USA.
Article Synopsis
- Crocodylians have a specialized gular valve that forms a water-tight seal in their mouths, allowing them to dive while keeping their mouths open.
- This study reveals that the gular valve consists of an integrated dorsal component (the dorsal gular fold) and a mobile ventral part (the tongue and hyolingual apparatus), connected by a newly identified structure called the velar chord.
- The findings suggest that the tension in the velar chord changes the shape of the dorsal gular fold, affecting various behaviors like swallowing and vocalization beyond just diving.
Biomimetic Hydrodynamic Sensor with Whisker Array Architecture and Multidirectional Perception Ability.

The rapid development of ocean exploration and underwater robot technology has put forward new requirements for underwater sensing methods, which can be used for hydrodynamic characteristics perception, underwater target tracking, and even underwater cluster communication. Here, inspired by the specialized undulated surface structure of the seal whisker and its ability to suppress vortex-induced vibration, a multidirectional hydrodynamic sensor based on biomimetic whisker array structure and magnetic 3D self-decoupling theory is introduced. The magnetic-based sensing method enables wireless connectivity between the magnetic functional structures and electronics, simplifying device design and endowing complete watertightness.

Watertight repair of the skull base defect is necessary during endonasal skull base surgery to avoid postoperative CSF leak (poCSFl) and consequent intracranial complications. Various techniques have been described for reconstructing sphenoid-sellar defects with varying success rates. We have described the immediate and long-term outcomes following the reconstruction of sphenoid-sellar defects with our technique.

LTW has the potential to revolutionize plastic surgery and wound healing techniques by its ability to produce watertight, scarless seals with minimal foreign body reaction. While using thermal mechanisms to achieve LTW, energy from the incident laser is absorbed by water in the tissue.
