Relationship between triphasic mechanical properties of articular cartilage and osteoarthritic grade

Alloreactivity and immunosuppressive properties of articular chondrocytes from osteoarthritic cartilage.

PURPOSE To determine whether articular chondrocytes derived from osteoarthritic knee joints could evoke alloreactive proliferation of peripheral blood mononuclear cells (PBMC) and inhibit mitogenic activity of polyclonally activated CD4+ major histocompatibility complex (MHC) class II- restricted T cells in vitro. METHODS Osteoarthritic cartilages of 17 patients aged 61 to 85 years were harve...

determination of some physical and mechanical properties red bean

چکیده: در این تحقیق، برخی خواص فیزیکی و مکانیکی لوبیا قرمز به-صورت تابعی از محتوی رطوبت بررسی شد. نتایج نشان داد که رطوبت بر خواص فیزیکی لوبیا قرمز شامل طول، عرض، ضخامت، قطر متوسط هندسی، قطر متوسط حسابی، سطح تصویر شده، حجم، چگالی توده، تخلخل، وزن هزار دانه و زاویه ی استقرار استاتیکی در سطح احتمال 1 درصد اثر معنی داری دارد. به طوری که با افزایش رطوبت از 54/7 به 12 درصد بر پایه خشک طول، عرض، ضخام...

Differential Immunohistochemical Expression Pattern of Galectin-3 in Normal and Osteoarthritic Human Articular Cartilage

Background: Previous studies have shown that Galectin-3, a member of lectin family, is expressed in developing cartilage in mouse embryo and also in growth plate of long bones.   Objective: In the present work, the expression pattern of Galectin-3 in normal and various grades of osteoarthritic (OA) human articular cartilage has been studied.   Methods: Using immunohistochemistry and standard we...

Simplifications of Triphasic Mixture Theory for Articular Cartilage

*Lu, XL; *Guo, XE; +*Mow, VC +*Department of Biomedical Engineering, Columbia University, New York, NY [email protected] INTRODUCTION The triphasic mixture theories for articular cartilage [1] have been successfully used to describe the flow-dependent and flow-independent viscoelastic behaviors, swelling behaviors, and electrokinetic behaviors of charged-hydrated soft tissues in the last two d...
