Objective: To evaluate the profilometric, esthetic, and patient-reported outcomes of peri-implant tissues in the maxillary anterior esthetic zone following guided bone regeneration (GBR) using the L-shape technique combined with delayed connective tissue grafting (CTG).
Materials And Methods: Profilometric and pink esthetic score (PES) measurements were performed at the time of implant surgery with GBR (T0) and at the 1- (T1), 2- (T2), and 3-year (T3) follow-up. Patient-reported outcomes were also assessed using the Oral Health Impact Profile-14 (OHIP-14) questionnaire. Statistical analysis over 3 years of follow-up assessed changes at time points (T0, T1, T2, and T3) and time periods (T0-T1, T0-T2, and T0-T3) using the Wilcoxon signed-rank test.
Results: A total of 12 patients (57.5 ± 12.3 years) were included in this study. The mean profilometric change in peri-implant tissues over the 3-year follow-up period was 3.49 ± 1.11 mm, and the buccal contours were not significantly different between the comparison periods. The PES remained stable, while all OHIP-14 domain scores improved significantly.
Conclusion: Simultaneous implant placement and GBR using the L-shape technique combined with delayed CTG in the maxillary anterior region provides stable buccal profiles and consistent esthetics and improves patient-reported quality of life over a 3-year period.
Clinical Significance: This study demonstrated that GBR using the L-shape technique combined with delayed CTG in the maxillary anterior region improved the buccal profile, esthetics, and patient-reported quality of life.

Aims: There is a potential association between oxidative stress and the development of diabetic kidney disease (DKD). The Oxidative Balance Score (OBS), derived from dietary and lifestyle factors, acts as a comprehensive marker of oxidative stress. Research examining the relationship between OBS and DKD is scarce.

Background: The preservation of olfaction during the surgical resection of anterior skull base meningiomas presents a significant challenge. This study presents a modified endonasal endoscopic L-shaped approach designed to maximize tumor resection while preserving olfaction, a vital function that profoundly impacts the quality of life.
Methods: A cadaveric dissection was conducted to refine the surgical technique, and this approach was subsequently applied to a 34-year-old female patient presenting with a large planum sphenoidale meningioma.
Variation of Stomach Shapes in Gastric Emptying Scintigraphy: Correlation With Gastric Emptying Results, Body Weight, and Symptoms.

Article Synopsis
- This study aimed to explore how different stomach shapes observed in gastric emptying scintigraphy (GES) relate to gastric emptying speeds, body weight, and GI symptoms.
- Researchers reviewed 397 GES studies, identifying five stomach shapes: crescentic, J-shaped, reversed-L, cylindrical, and bag-like, with crescentic being the most common.
- Findings revealed that crescentic stomachs had the highest body mass index (BMI), while bag-like stomachs showed the slowest gastric emptying and more severe regurgitation and heartburn symptoms.
Comparison of Three Computational Tools for the Prediction of RNA Tertiary Structures.

Understanding the structures of noncoding RNAs (ncRNAs) is important for the development of RNA-based therapeutics. There are inherent challenges in employing current experimental techniques to determine the tertiary (3D) structures of RNAs with high complexity and flexibility in folding, which makes computational methods indispensable. In this study, we compared the utilities of three advanced computational tools, namely RNAComposer, Rosetta FARFAR2, and the latest AlphaFold 3, to predict the 3D structures of various forms of RNAs, including the small interfering RNA drug, nedosiran, and the novel bioengineered RNA (BioRNA) molecule showing therapeutic potential.

The association between plasma low-density lipoprotein cholesterol (LDL-C) and atrial fibrillation (AF) recurrence after catheter ablation remains unclear. We aimed to assess the relationship between preprocedural LDL-C and the AF recurrence in patients undergoing catheter ablation. The cohort study consecutively included AF patients who underwent de novo catheter ablation between April 2021 and January 2023 in the Second Affiliated Hospital of Nanchang University in Jiangxi Province, China.
