Introduction: Since the mid-1900s, techniques in the repair of aortic arch and thoracoabdominal aortic pathologies have drastically evolved. Open aortic surgical repair was once the sole option for both simple and complex aneurysmal degeneration. Today, a number of minimally invasive and hybrid approaches are now available to assist both the surgeon and patient in tackling this challenging problem.

Purpose: To review the long history of wound management, including the methods of skin closure, asepsis, and anesthesia. Periocular techniques will be emphasized.
Methods: Literature searches and cross-referencing were used to identify historic reports addressing the management of wounds.

Intervertebral disc (IVD) degeneration represents a significant cause of chronic back pain and disability, with a substantial impact on the quality of life. Conventional therapeutic modalities frequently address the symptoms rather than the underlying etiology, underscoring the necessity for regenerative therapies that restore disc function. Polysaccharide-based materials, such as hyaluronic acid, alginate, chitosan, and chondroitin sulfate, have emerged as promising candidates for intervertebral disc degeneration (IVDD) therapy due to their biocompatibility, biodegradability, and ability to mimic the native extracellular matrix (ECM) of the nucleus pulposus (NP).

Background: The study focused on kinematically aligned total knee arthroplasty (KA TKA). It identified which coronal plane alignment of the knee (CPAK) types are associated with a higher proportion of medial deviation of the 6° prosthetic trochlear groove (PTG) relative to the quadriceps' line of pull and whether medial deviation adversely affected the Forgotten Joint Score (FJS). The research calculated the minimum PTG angle required to prevent medial deviation by at least 2° in all patients.

Magnetic random-access memory that uses magnetic tunnel junction memory cells is a high-performance, non-volatile memory technology that goes beyond traditional charge-based memories. Today, its speed is limited by the high magnetization of the memory storage layer. Here we prepare magnetic tunnel junction memory devices with a low magnetization ferrimagnetic Heusler alloy MnGe as the memory storage layer on technologically relevant amorphous substrates using a combination of a nitride seed layer and a chemical templating layer.
