[Relation between glycohemoglobin, hypoxia parameters and diabetic microangiopathy].

Numai utilizatorii înregistrați pot traduce articole

In normal persons and in diabetics with and without tissue injuries was tried to find out a connection between the glycolyzed haemoglobin and the parameters of hypoxia. In a small number of cases no clearly evident correlation between the concentrations of the 2,3-diphosphoglycerate and the lactate

[Oxygen exchange and acid-base status in patients with diabetic angiopathy of the lower extremities with different methods of conservative treatment].

In the pathogenesis of III-IV stage diabetic angiopathy, the important place belongs to oxygen deficiency and metabolic acidosis. Introduction into the complex of treatment of the patients of hyperbaric oxygenation and endolymphatic pharmacotherapy contributes to improvement of general state of the

Diabetic vascular disease. The importance of insulin deficiency, hyperglycemia and hypophosphatemia on red cell oxygen unloading.

Diabetes is associated with a fluctuating impairment in oxygen transport of the erythrocytes. This impairment is correlated with hyperglycemia by the formation of glycosylated hemoglobin (HbAIC) and with inhibitory factors of glycolysis i.e. hypophosphatemia and acidosis which lower the

[Pathogenetic mechanisms of diabetic microangiopathy].

The metabolic disorders, hormonal, genetic, immunological, reological factors, plasmorrhagia, hypoxia result in the simultaneous or subsequent damage to small vessels and thus are involved in the development of the diabetic microangiopathy. The degree of microangiopathy depends on the duration and

[Study on risk factors of tissue hypoxia in patients with diabetic retinopathy].

Risk factors of tissue hypoxia was investigated in 26 patients with diabetic retinopathy (DMR), who compared with 62 patients without DMR. significant higher incidence of DMR was found in patients with poor diabetic control (HbA 1 greater than or equal to 10%), with orthostatic hypotension (OH),

[Diabetic microangiopathy and oxygen transport disorder (a review of the literature and the authors' own data)].

Numai utilizatorii înregistrați pot traduce articole

Proceeding from biochemical and instrumental investigations on a vast material (560 patients with various forms of diabetes mellitus) and literature data the authors propose a new concept of occurrence and progression of diabetic microangiopathies. Importance is attached to tissue hypoxia related to

Pathogenesis of diabetic microangiopathy. The hemodynamic view.

Numai utilizatorii înregistrați pot traduce articole

Multiple factors, including altered levels of vasoactive substances, altered vasomotor responsiveness, chronic plasma volume expansion, and tissue hypoxia, contribute to a state of generalized microvascular vasodilatation in early insulin-dependent diabetes mellitus. This vasodilatation, with the

Evaluation of the Occlusive Arterial Disease and Diabetic Angiopathy Treatment Effects by Hyperbaric Oxygenation.

One of the most severe complications of atherosclerosis is arterial occlusive disease (AOD) and with diabetic angiopathy (DA), is a common chronic problem in clinical practice worldwide. Hyperbaric oxygen (HBO) therapy is a therapeutic modality for solving all forms of

G-CSF protects human brain vascular endothelial cells injury induced by high glucose, free fatty acids and hypoxia through MAPK and Akt signaling.

Granulocyte-colony stimulating factor (G-CSF) has been shown to play a neuroprotective role in ischemic stroke by mobilizing bone marrow (BM)-derived endothelial progenitor cells (EPCs), promoting angiogenesis, and inhibiting apoptosis. Impairments in mobilization and function of the BM-derived EPCs

Dynamic changes in the microcirculation of diabetics as related to diabetic microangiopathy.

Numai utilizatorii înregistrați pot traduce articole

Reversible abnormalities of many vascular beds have been observed in early diabetes, before irreversible structural changes of diabetic microangiopathy became apparent. In the bulbar conjenctiva and in the kidney the changes are associated with vascular dysfunction and may be due to autonomic

The role of insulin-like growth factor I and hypoxia inducible factor 1α in vascular endothelial growth factor expression in type 2 diabetes.

Numai utilizatorii înregistrați pot traduce articole

BACKGROUND Vascular endothelial growth factor (VEGF) plays an important role in diabetic vascular complications, and its expression is affected directly or indirectly by hypoxia inducible factor-1α (HIF-1α) and insulin-like growth factor-I (IGF-I) in tumors and certain normal cell lines. However,

Chordin-like 1, a bone morphogenetic protein-4 antagonist, is upregulated by hypoxia in human retinal pericytes and plays a role in regulating angiogenesis.

Numai utilizatorii înregistrați pot traduce articole

OBJECTIVE Pericytes play a specialized role in regulating angiogenesis and vascular function by providing vascular stability and controlling endothelial cell proliferation. Disorders in pericyte function and pericyte-endothelial interaction have been observed in several disease states including

Overexpression of Axl reverses endothelial cells dysfunction in high glucose and hypoxia.

Numai utilizatorii înregistrați pot traduce articole

The receptor tyrosine kinase Axl is involved in diabetic vascular disease. This study aims to investigate the effect of high glucose on endothelial cells injury and Axl expression in hypoxia condition in vitro, and we present details of the mechanism associated with overexpression of Axl rescue the

Diabetic microangiopathy.

Microvascular complications of diabetes include retinopathy, nephropathy and neuropathy. The first signs of these complications may develop in children and adolescents, particularly if insulin treatment has been inadequate. The mechanisms by which diabetic microangiopathy develop are not known, but

The problems of tissue oxygenation in diabetes mellitus. III. The "three-in-one concept" for the development of diabetic microangiopathy and a rational approach to its prophylaxis.

Numai utilizatorii înregistrați pot traduce articole

Evidence for a causative relationship between prolonged tissue hypoxia and diabetic retinopathy and glomerulosclerosis are presented. Based on the assumption that one of the most fundamental requirements for optimal cellular metabolism is a constant cellular oxygen tension, the "three-in-one
