Avascular necrosis of the right femoral head in female patient with Systemic Lupus Erythematosus

Indonesian Journal of Rheumatology, 2018
Avascular necrosis (also known as osteonecrosis, aseptic necrosis, or ischemic necrosis) represents collection of pathologic conditions from various etiologies causing impairment of blood supply to particular bone resulting in bone cellular death ...

Outcomes of total hip arthroplasty, as a salvage procedure, following failed internal fixation of intracapsular fractures of the femoral neck: a systematic review and meta-analysis. [PDF]

, 2016
AIMS: The optimal management of intracapsular fractures of the femoral neck in independently mobile patients remains open to debate. Successful fixation obviates the limitations of arthroplasty for this group of patients.

Rate of avascular necrosis after fracture dislocations of the proximal humerus

Obere Extremitat, 2018
BackgroundAvascular necrosis (AVN) of the humeral head is a severe complication after proximal humerus fracture dislocations, and leads to a poorer clinical outcome and subsequent revision surgeries.

Antioxidant Carbon Dot of Selenomethionine Alleviates Oxidative Stress in Intervertebral Disc Degeneration

Advanced Science, EarlyView.
A selenomethionine‐derived carbon dot (Se‐Met‐CD) serves as a potent nano‐antioxidant, efficiently scavenging reactive oxygen species, protecting nucleus pulposus cells from oxidative damage, restoring extracellular matrix homeostasis, and significantly mitigating intervertebral disc degeneration in vivo, which demonstrates great promise as a nanozyme ...

The vasculature and its role in the damaged and healing tendon [PDF]

, 2002
Tendon pathology has many manifestations, from spontaneous rupture to chronic tendinitis or tendinosis; the etiology and pathology of each are very different, and poorly understood. Tendon is a comparatively poorly vascularised tissue that relies heavily

A systematic review of undisplaced femoral neck fracture treatments for patients over 65 years of age, with a focus on union rates and avascular necrosis

Journal of Orthopaedic Surgery and Research, 2017
BackgroundIt remains unclear whether conservative treatment should be used to treat the common undisplaced femoral neck fractures that develop in the elderly.

Dual‐Pedicle Tissue‐Engineered Trachea Promotes Biomimetic Cartilaginous Framework, Vascularization, and Epithelial Lining for Long‐Segment Tracheal Reconstruction

Advanced Science, EarlyView.
Overcoming the limitations of conventional grafts, a biomimetic trachea with two independent vascular pedicles enables rapid integration and sustained patency. This approach markedly improves survival rates, restores the epithelial barrier, and promotes regenerative pathways, presenting a transformative paradigm for clinical application.

AVASCULAR TUMOUR DYNAMICS AND NECROSIS

Mathematical Models and Methods in Applied Sciences, 1999
We consider the dynamic growth of a tumour, concentrating on the possible development of a necrotic region and examine some simple tumour geometries in detail. The growth and death rates of the cells in the viable rim of the tumour are taken to be determined by the local oxygen concentration.

Osteonecrosis in genetic disorders [PDF]

, 2007
The avascular necrosis of bone is characterized by an abnormality of tissue that can occur whenever a disease process causes major cell stress. Some evidence supports a role for genetic factors in some avascular necrosis suggesting that gene mutations ...

Biomimetic Thalidomide Nanoparticles: Targeted and Sustained Therapeutic Strategy for Oxygen‐Induced Retinopathy

Aggregate, EarlyView.
Magnesium acetyl taurate and thalidomide co‐assembled nanoparticles (MT NPs) are prepared via Super‐stable Pure Nanomedicine Formulation Technology (SPFT), and the NPs are further coated with transferrin‐modified cell membrane vesicles to construct Tfm@MT nanomedicine for oxygen‐induced retinopathy treatment.
