Article Abstract
The accumulation of oxidative DNA base damage can severely disrupt the integrity of the genome and is strongly associated with the development of cancer. DNA glycosylase is the critical enzyme that initiates the base excision repair (BER) pathway, recognizing and excising damaged bases. The Nei endonuclease VIII-like 3 (NEIL3) is an emerging DNA glycosylase essential in maintaining genome stability. With an in-depth study of the structure and function of NEIL3, we found that it has properties related to the process of base damage repair. For example, it not only prefers the base damage of single-stranded DNA (ssDNA), G-quadruplex and DNA interstrand crosslinks (ICLs), but also participates in the maintenance of replication fork stability and telomere integrity. In addition, NEIL3 is strongly associated with the progression of cancers and cardiovascular and neurological diseases, is incredibly significantly overexpressed in cancers, and may become an independent prognostic marker for cancer patients. Interestingly, circNEIL3, a circular RNA of exon-encoded origin by NEIL3, also promotes the development of multiple cancers. In this review, we have summarized the structure and the characteristics of NEIL3 to repair base damage. We have focused on NEIL3 and circNEIL3 in cancer development, progression and prognosis.

Acute extremity compartment syndrome (CS) is a serious medical complication triggered by factors such as trauma, vascular injury, or prolonged compression, resulting in elevated intracompartmental pressure (ICP) and tissue ischemia. Diagnosis remains challenging, mainly relying on the subjective evaluation of clinical symptoms. Different animal models have been used to study pathophysiology and evaluate diagnostic and therapeutic approaches.

Purpose: The purpose of this study was to assess the reflectivity of the outer retinal layers (ORLs) in patients with central serous chorioretinopathy (CSCR) and to examine the relationship between the dimensions of the subretinal fluid (SRF) and ORL.
Methods: This retrospective, cross-sectional study included 33 eyes of 33 patients with CSCR and 33 age- and gender-matched controls. Unnormalized and relative reflectivities for the retinal pigment epithelium (RPE), the external limiting membrane (ELM), and the ellipsoid zone (EZ), as well as SRF height, base width, and area, were measured on optical coherence tomography images.

Introduction: During the healing process, the functional gradient attachment of the rotator cuff (RC) tendon-bone interface fails to regenerate, which severely impedes load transfer and stress dissipation, thereby increasing the risk of retears. As a result, the treatment of rotator cuff tears remains a significant clinical challenge.
Methods: In this study, a dual-crosslinked hyaluronic acid/polyethylene glycol (HA/PEG) hydrogel scaffold was synthesized using hyaluronic acid and polyethylene glycol as base materials.

Death-associated protein kinase 1 (DAPK1) is a Ca/calmodulin-regulated serine/threonine kinase that orchestrates a wide array of cellular activities. It is intricately regulated through multiple mechanisms, including intramolecular signaling and interactions with other proteins, such as kinases and phosphatases. DAPK1 plays a pivotal role in regulating various biological processes, including apoptosis and autophagy, and is implicated in pathogenesis of several disorders, such as cancer, stroke and brain damage, neurodegenerative and within their kinase domains.
