A case of a patient with IgG4+ plasma cell infiltration, an IgG4-related disease, localized to the auditory ossicles

Otolaryngology Case Reports, 2022
Immunoglobulin G4+ (IgG4+)-related disease may lead to lesions in various systemic organs. Based on several cases of patients with suspected IgG4-related Mikulicz's disease, the definitive diagnosis of IgG4-related Mikulicz's disease has been established,

Antigen preservation after decalcification: can we have a guideline for everyday bone-related laboratory routine?

, 2021
Introduction: The processing of the bone tissue presents multiple problems related to decalcification and it is often based on the experience of the operator.

An Experimental Study for Minimum Level of Decalcification to Detect the Osteolytic Bone Metastasis of Long Bone on Plain Radiography

Journal of Bone Metabolism, 2016
Background In 1951, Ardran reported that metastatic bone lesions could be detectable on plain radiography with 30% to 50% of decalcification. Authors performed experimental study for minimum level of decalcification to detect the osteolytic bone ...

Amuc_1473 Links Gut Microbes to Skeletal Homeostasis and Counteracts Multifactorial Osteoporosis

Advanced Science, EarlyView.
Amuc_1473, a previously uncharacterized protein enriched in Akkermansia muciniphila‐derived extracellular vesicles, is identified as a gut–bone messenger that promotes osteogenesis and inhibits osteoclastogenesis by engaging transcriptional and translational regulators in bone cells.

Optimization of perfusion decalcification for bones and joints in rats [PDF]

The Anatomical Record, 2000
Decalcification of osseous tissues by perfusion of decalcifying solution into the vascular system has never been applied to the study of peripheral joints. To optimize perfusion methods, rats were decalcified by direct immersion or by one of two perfusion techniques: 1) systemic perfusion circulating the decalcifying solution from the ascending aorta ...

Multi‐Omics Profiling Reveals Immunomodulatory and Pro‐Regenerative Effects of a Graphene Oxide–Collagen Scaffold in Massive Rotator Cuff Tears

Advanced Science, EarlyView.
A graphene oxide/collagen scaffold is developed for chronic massive rotator cuff tear repair. The scaffold improves compressive stability, supports reparative mesenchymal differentiation, and modulates the immune microenvironment. In chronic MRCT models, it reduces muscle degeneration, enhances tendon–bone regeneration, and improves functional recovery,

Bioadhesive Hydrogel With Polyphenol‐Armored Nanogene Rejuvenates Chondrocyte Senescence for Aged Osteoarthritis Therapy

Advanced Science, EarlyView.
An adhesive hydrogel depot with polyphenol‐armored nanogenes is developed for treating aged osteoarthritis. This system maintains miR‐140 bioactivity, prolongs its intra‐articular retention, and enhances transfection into chondrocytes, leading to the downregulation of senescence‐associated pathways.

DECALCIFICATION OF TEETH AND BONES, AND REGENERATION OF BONE THROUGH DIET [PDF]

JAMA: The Journal of the American Medical Association, 1922
That the teeth and bones are similar in structure has been recognized by nearly all physiologists. Chemically they are very much alike. According to Hoppe-Seyler, the inorganic constituents are the same for bone and for dentin, about 85 per cent, calcium phosphate and from 10 to 12 per cent, calcium carbonate.

Microwave-induced fast decalcification of rat bone for electron microscopic analysis: An ultrastructural and cytochemical study

, 2007
Bone decalcification is a time-consuming process. It takes weeks and preservation of the tissue structure depends on the quality and velocity of the demineralization process.

Hyperlipidemia Aggravates Alveolar Bone Loss via Periodontal Ligament Stem Cell Ferroptosis Through GSK3β Dependent Ubiquitin‐Mediated NRF2 Degradation

Advanced Science, EarlyView.
Lipid metabolic stress triggers ferroptosis in PDLSCs through the GSK3β/NRF2 pathway, thereby aggravating periodontal bone loss. Upregulated GSK3β promotes NRF2 ubiquitination and proteasomal degradation via β‐TrCP, suppressing NRF2 nuclear translocation and antioxidant target expression.
