Abstract

Shoulder pain and disabilities are prevalent issues among the elderly population, with rotator cuff tear (RCT) being one of the leading causes. Although surgical treatment has shown some success, high postoperative retear rates remain a great challenge, particularly in elderly patients. Aging‐related degeneration of muscle, tendon, tendon‐to‐bone enthesis, and bone plays a critical role in the development and prognosis of RCT. Studies have demonstrated that aging worsens muscle atrophy and fatty infiltration, alters tendon structure and biomechanical properties, exacerbates enthesis degeneration, and reduces bone density. Although recent researches have contributed to understanding the pathophysiological mechanisms of aging‐related RCT, a comprehensive systematic review of this topic is still lacking. Therefore, this article aims to present a review of the pathophysiological changes and their clinical significance, as well as the molecular mechanisms underlying aging‐related RCT, with the goal of shedding light on new therapeutic approaches to reduce the occurrence of aging‐related RCT and improve postoperative prognosis in elderly patients.

Abstract

Background: It is still in dispute as to whether a posterior approach is applied to reduce the posterior fractures of associated both-column acetabular fractures (ABC-AFs). Purpose: To analyze the morphological changes in the posterior elements including the posterior column (PC) and/or associated posterior wall (PW) fragments to provide a reference for surgical planning. Material and Methods: The 3D computed tomography (CT) data of 100 cases of ABC-AFs were retrospectively analyzed using Mimics and 3-Matic software. The line distribution of the retroacetabular surface (RAS), the acetabular fossa, and the size of the PW fragments were analyzed. Results: Fracture lines (n = 89) on RAS appeared in three patterns: transverse lines (n = 41) on the cephalic (65.8%) and caudal (29.3%) thirds; oblique lines (n = 34) on the mid-caudal thirds; and multifragmentary lines (n = 14). The lines of the displaced PW fragment (n = 61) were widely distributed in intra- and extra-articular regions. The mean radian of the PW fragments was >90° in 67.2% of cases and involved anteriorly to the vertex in 90.2% of cases. The average fracture span on the RAS was 0.60–1.00 in 63.9% of cases. The mean length of the spike of PW fragments was >20 mm in 80.3% of cases. Discussion: For PC fractures, transverse lines on the cephalic third of RAS indicated a possibility of the anterior approach, while transverse lines on the distal third or oblique and multifragmentary lines suggest the posterior approach. A displaced PW fragment was involved more extensively both intra-and extra-articularly and may be optimally treated via a posterior approach. [ABSTRACT FROM AUTHOR]

46. Lattice matched Z-scheme ZnIn2S4/Ag3PO4enhanced photocatalytic performance by controlling morphology synthesis

Abstract

Semiconductor materials have the capability to combine and form heterojunctions, yet traditional ones often result in interface defects due to lattice mismatch. On the other hand, lattice-matched heterojunctions boast smooth interfaces, facilitating charge transfer and enhancing photocatalytic efficacy. This study aims to manipulate the morphology of ZnIn2S4to resemble flowers, thereby increasing its active sites. Furthermore, adjusting the ZnIn2S4to Ag3PO4ratio forms Z-scheme heterojunctions, while employing natural zein as a substrate enables the creation of photocatalytic films via electrospinning for the degradation of CIP, a target pollutant. Through analysis of optoelectronic properties and photocatalytic assessments, it is evidenced that the amalgamation of ZnIn2S4and Ag3PO4forms a lattice-matched Z-scheme heterojunction, significantly enhancing the separation and transmission efficiency of photogenerated charge carriers, thereby improving photocatalytic performance. The most efficient film (ZnIn2S4/30 wt% Ag3PO4) achieves a 93.77 % degradation efficiency for CIP in 60 minutes and maintains stability over four cycles. Experiments capturing free radicals indicate •O2-radicals as the primary active species. Through density functional theory calculations and LC/MS-Q-TOF characterization, three potential degradation pathways for CIP are proposed. Antibacterial and cytotoxicity experiments confirm the broad-spectrum antibacterial activity and biocompatibility of ZnIn2S4/Ag3PO4@zein nano-photocatalytic films.
