Bridge to Healing: A Comprehensive Review of the Oroantral Fistula Journey
Oroantral fistula (OAF) is a pathological condition characterized by an abnormal communication between the oral cavity and the maxillary sinus. This communication leads to a persistent opening between these two anatomical regions, allowing the passage of oral fluids, food particles and microbial flora into the maxillary sinus. OAF can result from various causes including failed primary healing following dental extractions particularly in the posterior maxillary region, trauma, chronic dental infections, osteomyelitis, radiation therapy and iatrogenic complications during surgical procedures involving the maxilla. The clinical presentation of OAF often includes symptoms such as persistent or recurrent sinus infections, nasal discharge, foul taste or smell and sometimes even oro-nasal regurgitation of liquids. Diagnosis is typically confirmed through clinical examination and imaging studies such as dental radiographs or computed tomography (CT) scans, which help to visualize the fistulous tract and assess its size and extent. Management of OAF aims to close the fistulous tract and restore the integrity of the oral and sinus cavities. Treatment options vary depending on the size, location and underlying cause of the fistula. Conservative measures may include observation, nasal decongestants and antibiotics to control infection. However, surgical intervention is often necessary for definitive closure of the fistula. Surgical techniques range from simple primary closure with local flaps to more complex procedures involving bone grafts or soft tissue flaps depending on the size and complexity of the defect. This comprehensive review comprehensively explores the etiology, clinical manifestations, diagnostic modalities and management strategies pertaining to oroantral fistula (OAF).
Enhanced chloroplast FtsZ-ring constriction by the ARC6–ARC3 module in <i>Arabidopsis</i>
Chloroplast division, a process tightly linked to the energy demands of plants, is initiated by the formation of the stromal filamenting temperature-sensitive Z (FtsZ) ring. The Z ring is highly dynamic, and its constriction provides the essential force for chloroplast division. However, the regulatory mechanisms governing Z-ring dynamics and constriction remain poorly understood. Here, we report that the chloroplast inner envelope membrane (IEM) protein ACCUMULATION AND REPLICATION OF CHLOROPLASTS6 (ARC6) interacts with the chloroplast stromal protein ARC3, and this interaction is negatively regulated by the conserved J-like domain of ARC6. ARC3 is found both distributed throughout the stroma and localized to a ring-like structure at the chloroplast division site. We demonstrate that ARC6 recruits ARC3 to the division site to form a ring-like structure, likely through direct interaction. This ARC6–ARC3 interaction enables ARC3 to bind FtsZs. Furthermore, we show that the ARC6–ARC3 complex significantly promotes the dynamics of chloroplast Z rings reconstituted in a heterologous system. Finally, the constriction of these reconstituted Z rings is markedly enhanced by ARC6–ARC3. Our findings reveal a regulatory mechanism that governs Z-ring dynamics and constriction, shedding light on the molecular mechanisms underlying chloroplast division.

Impact of layer count and thickness on spin wave modes in multilayer synthetic antiferromagnets
Abstract In this study, the spin-wave spectrum in multilayer synthetic antiferromagnets is calculated. The analysis focuses on the effects of varying both the thicknesses and the number of ferromagnetic layers within these structures. The results reveal that a non-reciprocal spin-wave dispersion occurs in structures with an even number of layers, while a reciprocal dispersion of two counterpropagating waves is observed for systems with an odd number of layers. As the number of layers and their thickness increase, the study identifies the distinctive presence of bulk and surface modes, with the latter being strongly affected by dynamic dipolar interactions. In multilayers with an even number of layers, such surface modes exhibit nonreciprocal behavior, maintaining their surface character only in one propagation direction. Conversely, in odd-layer systems, the symmetric counterpropagating surface modes have similar properties. Additionally, the bulk modes for both even and odd numbers of layers converge towards similar dynamic behavior as the thickness and number of layers increase. As the thickness of the ferromagnetic layers increases, the surface modes in multilayers with an odd number of layers remain localized at either the top or bottom, depending on the sign of the wave vector. In contrast, for the even case, the surface modes appear in both the top and bottom ferromagnetic layers when the layers are thin or ultrathin. However, as the ferromagnetic layer thickness increases, these modes gradually become predominantly localized at either the top or bottom of the multilayer. Finally, the study explores the application of an external magnetic field, demonstrating that surface chiral modes are absent in the saturated state, resulting in a reciprocal spin-wave dispersion. This establishes a magnetic field-mediated control over non-reciprocal localized surface modes.

Obstructive Sleep Apnea and Dentistry: A Detailed Review of Current Perspectives and Clinical Impact
Major effects on oral and systemic health resulting from the challenging sleep-associated respiratory disorder known as obstructive sleep apnea are related to: Research revealing similar anatomical and functional areas between dentistry and sleep medicine underscores the increasing relevance of the dental practitioner in OSA treatment. Combining insights from multiple patient backgrounds, this overview presents the current knowledge on the objectives of dentistry in the screening, diagnosis, and treatment of obstructive sleep apnea. Together with craniofacial risk factors and intraoral symptoms observed in dental examinations, the pathogenesis and typical clinical characteristics of OSA are discussed in the review. Oral appliance treatment is being closely examined in conjunction with continuous positive airway pressure therapy, with an emphasis on design modifications, clinical efficacy, and long-term outcomes. Utilizing maxillomandibular advancement and interceptive orthodontics, this research explores orthodontic and surgical treatment options. These methods demonstrate the extent to which structural dental alterations increase airway patency. The paper addresses current challenges to effective use, including constraints in the area of practice, patient adherence issues, and instructional gaps. Ultimately, it advances research on digital technologies, outcome monitoring, and interprofessional training projects. By orienting dental practitioners as cooperative participants in OSA treatment, this research highlights the importance of developing integrated clinical pathways and strengthening training frameworks to facilitate evidence-based practice in dental sleep medicine.
Ena/VASP-EVH1 inhibition prevents chemotaxis and metastasis by blocking the EVH1–WAVE2 interaction
Cancer therapy would benefit from suppressing cancer cell motility in the process of metastasis. Such directed cell migration relies on the propulsive force established by the filamentous actin network within lamellipodia. Proteins of the Ena/VASP family and the WAVE regulatory complex orchestrate lamellar protrusions and therefore provide promising targets for pharmacological interventions. Here, we report a cross-talk between Ena/VASP proteins and WAVE2 that is important for cancer cell extravasation. Mutating the EVH1 domain recognition motif in WAVE2 abrogates chemotaxis of triple-negative MDA-MB-231 breast cancer cells and reduces their extravasation in a zebrafish model. In pilot experiments, orthotopic implantation of these cells into mice led to a reduction in macrometastasis, resulting in prolonged survival. Similarly, intervention by an Ena/VASP-EVH1 inhibitor also reduced metastasis in vivo. Our results suggest that pharmacological interference with the Ena/VASP–WAVE2 interaction may thus reduce metastasis.
