The question of strains in AA amyloidosis.
Sci Rep

Department of Immunology, Genetics and Pathology, Uppsala University, Rudbeck Laboratory, C11, 75185, Uppsala, Sweden.
The existence of transmissible amyloid fibril strains has long intrigued the scientific community. The strain theory originates from prion disorders, but here, we provide evidence of strains in systemic amyloidosis. Human AA amyloidosis manifests as two distinct clinical phenotypes called common AA and vascular AA.

Osteoblastogenesis is governed by complex interplays among signaling pathways, which modulate the expression of specific markers at each differentiation stage. This process enables osteoblast precursor cells to adopt the morphological and biochemical characteristics of mature bone cells. Our study investigates the role of NOTCH signaling in osteogenesis in MC3T3-E1 and C3H10T1/2 cell lines.

Characterization and formation of the biomineral aragonite structures of the Noah's Ark shell ( L.,1758) were studied from structural, morphogenetic, and biochemical points of view. Structural and morphological features were examined using X-ray diffraction, field-emission scanning electron microscopy, and atomic force microscopy, while thermal properties were determined by thermogravimetric and differential thermal analyses.

Introduction: Ulcerative colitis (UC), a form of inflammatory irritable bowel disease, is characterized by a recurrent and persistent nonspecific inflammatory response. Polydatin (PD), a natural stilbenoid polyphenol with potent properties, exhibits unexpected beneficial effects beyond its well-documented anti-inflammatory and antioxidant activities. In this study, we presented evidence that PD confers protection against dextran sodium sulfate (DSS)-induced ulcerative colitis.

The anatomical and cytological characteristics of the mucilage-secretory system have been widely studied in Malvaceae. However, conflicting information regarding the morphological nature of secretory structures exists, and some remain poorly understood. In this sense, some secretory structures in Malvaceae are not characterized as typical isolated idioblasts, canals, or cavities.
