Semi‐supervised classification of fundus images combined with CNN and GCN

open access: yesJournal of Applied Clinical Medical Physics, Volume 23, Issue 12, December 2022., 2022
Abstract Purpose Diabetic retinopathy (DR) is one of the most serious complications of diabetes, which is a kind of fundus lesion with specific changes. Early diagnosis of DR can effectively reduce the visual damage caused by DR. Due to the variety and different morphology of DR lesions, automatic classification of fundus images in mass screening can ...

A human inhibitor of tumor necrosis factor alpha. [PDF]

open access: yesThe Journal of experimental medicine, 1988
Urine of some febrile patients exhibits a TNF-alpha inhibitory activity (TNF-alpha INH), sensitive to heat and trypsin, with an apparent mol wt of 40-60 X 10(3) and a pI range of 5.5-6.1. As for the Il-1 INH, the TNF INH activity involves a competitive mechanism of action suggesting the existence of a family of negative feedback-regulating molecules ...

Expression of tumor necrosis factor-alpha–converting enzyme and tumor necrosis factor-alpha in human myocarditis

open access: yesJournal of the American College of Cardiology, 2000
We determined whether tumor necrosis factor-alpha-converting enzyme (TACE) is expressed with tumor necrosis factor-alpha (TNF-alpha) in myocarditis.Tumor necrosis factor-alpha-converting enzyme, which has recently been identified as belonging to the family of metalloproteinase disintegrin proteins, is responsible for the conversion of TNF-alpha ...

The role of tumor necrosis factor-α and natural killer cells in uterine artery function and pregnancy outcome in the stroke prone spontaneously hypertensive rat [PDF]

open access: yes, 2016
Women with chronic hypertension are at increased risk of maternal and fetal morbidity and mortality. We have previously characterized the stroke-prone spontaneously hypertensive rat (SHRSP) as a model of deficient uterine artery function and adverse ...

Efficient presentation of soluble antigen by cultured human dendritic cells is maintained by granulocyte/macrophage colony-stimulating factor plus interleukin 4 and downregulated by tumor necrosis factor alpha

open access: yesJournal of Experimental Medicine, 1994
Using granulocyte/macrophage colony-stimulating factor (GM-CSF) and interleukin 4 we have established dendritic cell (DC) lines from blood mononuclear cells that maintain the antigen capturing and processing capacity characteristic of immature dendritic ...

Tumor necrosis factor alpha and mesangial cells

open access: yesKidney International, 1992
Bacterial infections promote important alterations in immune, hemodynamic, and metabolic function which can result in irreversible shock. These changes are mediated by host-secreted cytokines rather than by direct action of the endotoxin lipopolysaccharide (LPS) derived from the cell wall of bacteria.

Increased adipose tissue expression of tumor necrosis factor-alpha in human obesity and insulin resistance.

open access: yesJournal of Clinical Investigation, 1995
Obesity is frequently associated with insulin resistance and abnormal glucose homeostasis. Recent studies in animal models have indicated that TNF-alpha plays an important role in mediating the insulin resistance of obesity through its overexpression in ...

Role of tumor necrosis factor-α and its receptors in diesel exhaust particle-induced pulmonary inflammation [PDF]

open access: yes, 2017
Inhalation of diesel exhaust particles (DEP) induces an inflammatory reaction in the lung. However, the underlying mechanisms remain to be elucidated. Tumor necrosis factor alpha (TNF-alpha) is a proinflammatory cytokine that operates by binding to tumor

Effects of a polymorphism in the human tumor necrosis factor alpha promoter on transcriptional activation.

open access: yesProceedings of the National Academy of Sciences of the United States of America, 1997
Tumor necrosis factor alpha (TNF alpha) is a potent immunomodulator and proinflammatory cytokine that has been implicated in the pathogenesis of autoimmune and infectious diseases.

Evaluation of Tumor Necrosis Factor Alpha Polymorphism Frequencies in Endometriosis [PDF]

open access: yesInternational Journal of Fertility and Sterility, 2015
Background The pro-inflammatory cytokine, tumor necrosis factor-alpha (TNF-α), is a pathogenic element for a number of disorders. Previous studies have reported that the -1031 T/C and -238 G/A polymorphisms in the promoter region of the TNF-α gene are ...
