OBJECTIVE: The aim of this study was to evaluate the association of nailfold videocapillaroscopy (NVC) changes with the presence and severity of interstitial lung disease (ILD) in systemic sclerosis. METHODS: This was a cross-sectional analysis of 48 systemic sclerosis patients (21 patients with ILD). The NVC characteristics considered were capillary organization, capillary loss (CL), avascular areas, enlarged and giant capillaries, hemorrhages, abnormally shaped capillaries, edema, and intermittent flux...

Objective: To sonographically evaluate the dominant fibroid nodule vascularity and flow velocity pattern of perifibroid and intrafibroid arteries. Methods: We recruited 140 women with uterine fibroids. Their uteri were scanned to determine the vascularity of fibroid nodules and the Doppler indices of the fibroid arteries. Results: The median volume of the dominant leiomyoma nodule was 133 cm3 (range=1.5-2,575 cm3 ). Eighty-three subjects (59...

Uterine leiomyoma is characterized by abundant extracellular matrix and broad avascular areas, both constantly resulting in hypoxia, suggesting some hypoxia-induced response function. Here, we examined whether hypoxia-inducible factor 1α (HIF-1α)- mediated hypoxic response function in uterine leiomyoma. Immunoblotting detected higher basal HIF-1α protein expression in nuclear extracts from uterine leiomyoma tissues than in those from the adjacent myometrium ( P = .0011). Immunohistochemical analysis revealed the presence of HIF-1α-positive cellular components in both leiomyoma and surrounding myometrial tissues...

BACKGROUND: The development of models that incorporate intact microvascular networks enables the investigation of multicellular dynamics during angiogenesis. Our laboratory introduced the rat mesentery culture model as such a tool, which would be enhanced with mouse tissue. Since mouse mesentery is avascular, an alternative is mouse mesometrium, the connective tissue of uterine horns. The study's objective was to demonstrate that mouse mesometrium contains microvascular networks that can be cultured to investigate multicellular dynamics during angiogenesis...

Identifying sickle cell disease patients at high risk of complications could lead to personalized treatment and better prognosis but despite many advances prediction of the clinical course of these patients remains elusive. We propose a system-type approach to discover profiles of multiple, common biomarkers that correlate with morbidity and mortality in sickle cell disease. We used cluster analysis to discover 17 signatures of 17 common circulating biomarkers in 2320 participants of the Cooperative Study of Sickle Cell Disease, and evaluated the association of these signatures with risk for stroke, pain, leg ulceration, acute chest syndrome, avascular necrosis, seizure, death, and trend of fetal hemoglobin and hemolysis using longitudinally collected data...

Extracorporeal shockwave therapy (ESWT) is a technology that was first introduced into clinical practice in 1982 for urological conditions. Subsequent clinical applications in musculoskeletal conditions have been described in treatment of plantar fasciopathy, both upper and lower extremity tendinopathies, greater trochanteric pain syndrome, medial tibial stress syndrome, management of non-union fractures, and joint disease including avascular necrosis (AVN). The aim of this review is to summarize the current understanding of treatment of musculoskeletal conditions with ESWT, accounting for differences in treatment protocol and energy levels...

In France, endothelial dysfunction represents approximately one half of the indications for corneal transplants performed each year. However, the use of endothelial keratoplasty is limited by the technical difficulty of the procedure, a shortage of available grafts, and the potential for graft failure or rejection. These limitations are driving researchers to develop new, less invasive, and more effective therapies. Corneal endothelial cell therapy is being explored as a potential therapeutic measure, to avoid the uncertainty associated with grafting...

The oxygen-induced retinopathy (OIR) animal model established in C57 mice and SD rats has been widely used in retinal neovascular disease studies, while Balb/c mice have not been used because Balb/c OIR mice lack neovascular tufts. One study found a substantial difference in the density of retinal microglia between C57 and Balb/c mice; however, no direct evidence could clarify whether the density of retinal microglia in Balb/c mice led to this difference. In our study, intraperitoneal injection of minocycline was used to inhibit the activation of microglia and intravitreal injection of clodronate liposomes was used to decrease the density of microglia in Balb/c OIR model mice...

Objective: Corticosteroids are a mainstay of SLE treatment; however, cumulative steroid exposure may lead to organ damage. This study aimed to quantify the risk of new diabetes, hypertension, cataracts, osteoporosis and avascular necrosis that is attributable to cumulative corticosteroid exposure in SLE. Methods: Using data from the Hopkins Lupus Cohort, a longitudinal study of lupus activity, organ damage and quality of life in patients with SLE, five matched case-control analyses nested within a prospectively enrolled SLE cohort were performed...

BACKGROUND: There is no consensus about the duration of post-operative immobilization in the treatment of DDH (developmental dysplasia of hip). Our aim in this study is to compare between two post-operative immobilization protocols for patients undergoing open reduction. MATERIALS AND METHODS: Thirty-eight hips in 32 patients assigned to group A were immobilized in hip spica for four weeks followed by abduction brace application which was gradually weaned through the periods of several months and 29 hips in 24 patients assigned to group B immobilized in hip spica for 12 weeks without further bracing...

Avascular necrosis of the femoral head (ANFH) is a consequence of ischemia. Although the majority of cases of ANFH are sporadic, certain familial cases of ANFH have been reported to be associated with collagen type II α1 chain (COL2A1) mutations, which lead to COL2A1 gene dysfunction. The structure of secreted type II collagen contains a core area with a triple helical glycine (Gly)‑X‑Y domain, and the replacement of Gly in this region as a result of COL2A1 mutations may damage the structure of type II collagen...

Avascular necrosis of the femoral head (ANFH) is an a frequently occurring orthopaedic disease with high morbidity. Traditional Chinese Medicine (TCM) Yuanshi Shengmai Chenggu Tablet is a valid prescription for treating steroid-induced femoral head necrosis. However, there are rare investigations about the serum protein marker expression after the acting of drugs on hormone and TCM. In the present study, we aimed to systematically discover and validate the serum biomarkers expression difference in patients with steroid-induced avascular necrosis of femoral head (SANFH) after taking Yuanshi Shengmai Chenggu Tablets (SANFH-TCM), so as to reveal the action mechanism of TCM from the molecular level by using isobaric tags for relative and absolute quantification (iTRAQ) with multiple reaction monitoring quantification...

In the cornea, healing of the wounded avascular surface is an intricate process comprising the involvement of epithelial, stromal and neuronal cell interactions. These interactions result to the release of various growth factors that play prominent roles during corneal wound healing response. Bone morphogenetic proteins (BMPs) are unique multi-functional potent growth factors of the transforming growth factor-beta (TGF-β) superfamily. Treatment of corneal epithelial cells with substance P and nerve growth factor resulted to an increase in the expression of BMP7 mRNA...

The mechanisms involved in tumor growth mainly occur at the microenvironment, where the interactions between the intracellular, intercellular and extracellular scales mediate the dynamics of tumor. In this work, we present a multi-scale model of solid tumor dynamics to simulate the avascular and vascular growth as well as tumor-induced angiogenesis. The extracellular and intercellular scales are modeled using partial differential equations and cellular Potts model, respectively. Also, few biochemical and biophysical rules control the dynamics of intracellular level...
