It has been shown on animals with experimental histamine edema under acute hypoxic hypoxia that anti-inflammatory properties of the known non-steroidal antiphlogistics and new derivatives of fumaric acid heterylamides administered in a dose of 10% of the LD50 underwent changes. At "altitudes" of
OBJECTIVE
To investigate the clinical value of vascular endothelial growth factor (VEGF) and hypoxia-inducible factor-1alpha (HIF-1alpha) in diagnosing malignant and tuberculous pericardial effusion.
METHODS
Eighty patients with exudative pericardial effusion undergoing pericardiocentesis and
A group of Wistar albino rats was injected subcutaneously with monocrotaline to induce vasoconstrictive hypertensive pulmonary vascular disease characterized by medial hypertrophy of small pulmonary arteries, the appearance of muscular pulmonary arterial vessels of arteriolar dimensions (less than
OBJECTIVE
Thoracentesis is performed to identify the cause of a pleural effusion. Although generally safe, thoracentesis may be complicated by transient hypoxemia, bleeding, patient discomfort, reexpansion pulmonary edema, and pneumothorax.
OBJECTIVE
To identify the best means for differentiating
Exposure to high oxygen (O2) concentrations, especially in the neonate, is associated with the development of pathologic syndromes characterized by vascular involvement including the retinopathy of prematurity. Some of the initial vascular changes observed appear consistent with a reduction in
OBJECTIVE
To define the role of hypoxia and vascular endothelial growth factor (VEGF) in modifying the pattern, density, and permeability of the retinal vasculature in mouse models in which Norrin/Frizzled4 signaling is impaired.
METHODS
Retinal vascular structure was analyzed in mice with mutation
Hif-1α is a master regulator which involved in the transcriptional regulation of anti-inflammatory or cellular responding to hypoxia. Previous work shows that the absence of Hif-1α results in the destruction of intestinal epithelial cell (IEC) and abnormalities of intestinal barrier function.
The mammalian CNS is capable of tolerating chronic hypoxia, but cell type-specific responses to this stress have not been systematically characterized. In the Norrin KO (NdpKO ) mouse, a model of familial exudative vitreoretinopathy (FEVR), developmental hypovascularization of the
Aberrant growth of blood vessels in the choroid layer of the eye, termed choroidal neovascularization (CNV), is the pathological hallmark of exudative age-related macular degeneration (AMD), causing irreversible blindness among the elderly. Co-localization of proangiogenic factors and hypoxia
OBJECTIVE
Oleic acid-induced lung injury is an established experimental model of acute lung injury in pigs and is considered to reproduce the early exudative phase of acute respiratory distress syndrome. Ultrasound lung comets are an echographic sign of extravascular lung water, originating from
An infant presented with multifocal myoclonus and cyanotic hypoxemia immediately after birth, and severe feeding problems, a protein-losing enteropathy, massive ascites and grand-mal epilepsy marked his rapid downhill course, with death at 17 weeks. At 2 weeks, brain MRI revealed grey matter
Disorders of the heart frequently cause pulmonary dysfunction because of the close structural and functional association of the heart and lungs. The pulmonary vasculature is very commonly affected by cardiac pathology. The pulmonary vasculature is normally a low-pressure, low-resistance circuit with
Lung repair after diffuse alveolar damage (DAD) may be modified by supportive therapy or the occurrence of complications. To provide a clinically relevant model of DAD, we studied the feasibility of long-term respiratory support of 5 normal baboons and 20 baboons with oleic-acid-induced lung injury.
A total of 117 patients with pulmonary interstitial diseases (PID) were examined. The functional activity of alveolar macrophages was assayed in the lavage fluid and in lung tissue biopsy specimens from the generation of active oxygen forms, the secretion of tumor necrosis factor, fibronectin,
Sphingosine 1-phosphate (S1P) is a potent lipid mediator that modulates inflammatory responses and proangiogenic factors. It has been suggested that S1P upregulates choroidal neovascularization (CNV) and may be deeply involved in the pathogenesis of exudative age-related macular degeneration (AMD).
