AI Article Synopsis
- The study evaluated patients with suspected connective tissue diseases who tested positive for anti-Sm/RNP and/or anti-RNP antibodies to understand their clinical features.
- It involved measuring antibody levels and comparing clinical symptoms among three groups: those positive for anti-RNP only, anti-Sm/RNP only, and those positive for both.
- Results showed that patients with both antibody types had significantly higher rates of inflammatory arthritis and Raynaud phenomenon, suggesting a stronger association with diagnoses like mixed connective tissue disease (MCTD) and systemic lupus erythematosus (SLE).
Article Abstract
Objective: This study aimed to evaluate the clinical features in patients with suspected connective tissue disease who tested positive for anti-Sm/RNP common motif antibody with or without associated anti-RNP antibody.
Methods: The titers of anti-Sm/RNP and anti-RNP antibodies were measured by the multiplex solid-phase bioassays (Bio-Rad). Clinical manifestations were compared among the three subgroups (RNP only, Sm/RNP only, and double positive for RNP and Sm/RNP). Patients were further evaluated for the diagnosis of mixed connective tissue disease (MCTD) and/or systemic lupus erythematosus (SLE) using accepted classification criteria.
Results: A total of 133 patients were included in this study. The rates of inflammatory arthritis and Raynaud phenomenon were significantly higher in patients testing positive for both anti-RNP and anti-Sm/RNP antibodies compared to anti-RNP only or anti-Sm/RNP only (69.1% vs 28.8% vs 25.0%, P < 0.0001 for arthritis and 59.5% vs 23.3% vs 37.5%, P = 0.0005 for Raynaud phenomenon). Area under the curve (AUC) values were 0.68 (95% confidence interval [CI] 0.59-0.77, P < 0.0001) for anti-Sm/RNP titers and 0.65 (95% CI 0.55-0.74, P = 0.0039) for anti-RNP titers with inflammatory arthritis. AUC values were 0.67 (95% CI 0.58-0.77, P = 0.0002) for anti-Sm/RNP titers and 0.59 (95% CI 0.49-0.69, P = 0.0352) for anti-RNP titers with Raynaud phenomenon. The odds ratios for the diagnosis of MCTD and SLE were significantly higher in patients with double positivity compared to those testing solely positive for anti-RNP antibody.
Conclusion: Anti-Sm/RNP common motif autoreactivity when combined with anti-RNP antibody positivity identifies those patients who are closely related with certain clinical manifestations and who are associated with well-defined connective tissue disease such as MCTD or SLE.

Objective: Neonatal skeletal articulations for research and display purposes are uncommon due to issues surrounding incomplete bone maturation and reduced structural integrity that affect the bone preparation and articulation procedures. The present project was designed to add to the veterinary literature on neonatal moose osteological specimens, document the procedures of preparing and articulating a delicate specimen, and construct a 3-dimensional (3D) scan of the articulated skeleton that could be used for scientific and veterinary research and study worldwide.
Animal: A neonatal moose that had succumbed to capture myopathy resulting from entanglement in a barbed wire fence was the sole subject of this project.
3D-Printed PCL-Based Scaffolds with High Nanosized Synthetic Smectic Clay Content: Fabrication, Mechanical Properties, and Biological Evaluation for Bone Tissue Engineering.

Background: The 3D printing of macro- and mesoporous biomimetic grafts composed of polycaprolactone (PCL) infused with nanosized synthetic smectic clay is a promising innovation in biomaterials for bone tissue engineering (BTE). The main challenge lies in achieving a uniform distribution of nanoceramics across low to high concentrations within the polymer matrix while preserving mechanical properties and biological performance essential for successful osseointegration.
Methods: This study utilized 3D printing to fabricate PCL scaffolds enriched with nanosized synthetic smectic clay (LAP) to evaluate its effects on structural, chemical, thermal, mechanical, and degradative properties, with a focus on in vitro biological performance and non-toxicity.

The diagnostic process and discrimination of mucosal lesions present a formidable challenge for numerous clinicians, primarily attributable to the common overlap of clinical manifestations observed across various categories, including infectious, autoimmune, connective tissue, and systemic vascular inflammatory diseases. In cases of mucosal lesions, syphilis presents distinctive characteristics that can help clinicians differentiate it from other conditions. The most common manifestation of primary syphilis is mostly a painless, firm, indurated ulcer known as a chancre, which typically appears at the site of inoculation, with enlargement of regional lymph nodes.

Neuromyelitis optica spectrum disorder (NMOSD) includes conditions with autoimmune genesis, which are manifested by attacks of optic neuritis (ON) and transverse myelitis (TM), and also express aquaporin 4 (NMO-IgG) or myelin oligo-endocytic glycoprotein (MOGAb) antibodies. In rare cases, the disease may also have a clinical presentation with only TM, without ON or with ON, without TM. These conditions are also included in the spectrum.

Background: Recently, autologous cultured fibroblast and platelet-rich plasma (PRP) therapies have been attempted for skin rejuvenation. Unlike PRP, grafted fibroblasts not only produce connective tissue but also influence the surrounding environment through a paracrine effect. Fibroblast-derived cytokines interact with and are modulated by neighboring tissue-constituting cells.
