Article Abstract
A clinical case of successful application of platelet-rich fibrin (PRF) to eliminate a large residual cavity after enucleation of a radicular cyst is described. The method is based on the use of biological substances that produce growth factors that stimulate reparative osteogenesis. A similar source of growth factors is PRF. According to the literature, it is able to reduce inflammation of periodontal tissues, preserve the location of the alveoli and eliminate defects in the alveolar bone, thereby enhancing bone regeneration and ensuring its good stability. PRF is easy to manufacture, does not require the appointment of anticoagulants, is resistant to stretching and elastic, while it can be used independently and in combination with various bone plastic materials. In our study, the use of PRF allowed not only to eliminate a large residual cavity after enucleation of a radicular cyst, which was confirmed by the results of cone beam computed tomography, but also to preserve the functionality of the teeth in an aesthetically significant area.

Hepatitis B virus (HBV) exclusively infects hepatocytes and produces large quantities of subviral particles containing its surface antigen (HBsAg). T cells play a central role in controlling HBV infection but can also mediate liver injury and contribute to disease progression. However, the mechanisms that regulate T-cell responses to eliminate the virus without causing immunopathology during acute HBV infection remain poorly defined.

Context: Newborn screening (NBS) for 21-hydroxylase deficiency (21OHD) has historically shown high false positive (FP) rates, especially in low birth weight (LBW) infants. In 2022, we proposed a second-tier liquid chromatography-tandem mass spectrometry (LC-MS/MS)-based algorithm to improve screening specificity; however, its real-world performance remains unassessed prospectively.
Objective: To prospectively evaluate our LC-MS/MS-based screening algorithm for 21OHD and develop a refined version addressing newly identified clinical limitations.

Background: Frequent premature atrial complexes (PACs) can increase the risk of atrial fibrillation or atrial tachycardia, and pharmacological therapy can be challenging.
Objective: To report the use of three-dimensional electro-anatomical mapping of PAC originating from the right atrial free wall and treatment by radiofrequency ablation in three horses.
Study Design: Retrospective case report.

3D shape defect detection plays an important role in autonomous industrial inspection. However, accurate detection of anomalies remains challenging due to the complexity of multimodal sensor data, especially when both color and structural information are required. In this work, we propose a lightweight inter-modality feature prediction framework that effectively utilizes multimodal fused features from the inputs of RGB, depth and point clouds for efficient 3D shape defect detection.

Reproducibility and research integrity are foundational tenets to scientific discovery, which are produced utilizing well-established, proven principles and protocols. Furthermore, with the ever-increasing prevalence and burden cardiovascular disease (CVD) places on individuals and society at large, it deems essential to cultivate robust and validated model for investigation. Our group utilizes a two-surgery protocol in a swine model that has been progressively refined over the last twenty years, in which we first induce chronic myocardial ischemia by placement of an ameroid constrictor mimicking the pathophysiology of coronary artery disease (CAD) in humans.
