Type 2 diabetes is associated with vascular dysfunction, accelerated atherosclerotic morbidity, and mortality. Abnormal vasomotor responses to chemoreflex activation may contribute to the acceleration of atherosclerotic diabetes complications, but these responses have not previously been
Type 2 diabetes mellitus was modeled in newborn albino rat pups. Metabolism and contractile activity of isolated heart under conditions of hypoxia were studied on adult rats. Contractile activity of the myocardium in animals with type 2 diabetes mellitus and abdominal obesity decreased during
BACKGROUND
Obstructive sleep apnea (OSA) has been shown to be associated with type 2 diabetes mellitus (DM). Studies on healthy individuals found that OSA is associated with lower insulin sensitivity. We hypothesized that nocturnal hypoxemia from OSA is associated with poorer glycemia in severely
Sleep apnea syndrome (SAS) is a very common disease involving intermittent hypoxia (IH), recurrent symptoms of deoxygenation during sleep, strong daytime sleepiness, and significant loss of quality of life. A number of epidemiological researches have shown that SAS is an important risk factor for
Limited reports exist on the relationships between regulation of oxygen homeostasis and circadian clock genes in type 2 diabetes. We examined whether the expression of Hypoxia-Inducible Factor-1α (HIF-1α) and HIF-2α relates to changes in the expression of clock genes (Period homolog proteins (PER)1,
OBJECTIVE
To elucidate the role of heat shock protein-70 (HSP70) and hypoxia inducible factor-1α (HIF-1α) in diabetic retinopathy (DR) patients.
METHODS
A comparative study was done on the serum level of both HSP70 and HIF-1α in 50 patients with type 2 diabetes mellitus (T2DM) without DR, 50
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,
We previously showed that nightly exposure to moderate hypoxia reduces fasting glucose levels and improves both whole-body skeletal muscle and hepatic insulin sensitivity in individuals with obesity. The goal of this study was to extend this observation in an "at home" setting and
OBJECTIVE
The incidence of Type 2 diabetes is increasing, along with its associated micro- and macrovascular disease manifestations. Previous studies indicate that patients with Type 2 diabetes exhibit abnormal cardiopulmonary reflex responses to various stimuli, although the impact of hypoxia, a
OBJECTIVE
This study investigated the association between intermittent hypoxia and glycaemic control in patients with uncontrolled type 2 diabetes (T2D) not treated for sleep apnoea.
METHODS
This was a single-centre cross-sectional study of stable patients with T2D and HbA1c ≥7% (53 mmol/mol).
OBJECTIVE
We estimated the prevalence of nocturnal intermittent hypoxia, a surrogate marker of obstructive sleep apnoea, among type 2 diabetes mellitus (T2DM) patients and examined the association between nocturnal intermittent hypoxia and microvascular diseases.
METHODS
We recruited 513 Japanese
OBJECTIVE
Although the associations between obstructive sleep apnoea and type 2 diabetes mellitus have been reported in cross-sectional design studies, findings on the prospective association between the two conditions are limited. We examined prospectively the association between nocturnal
BACKGROUND
Metabolic syndrome (MetS) is characterized by central obesity, insulin resistance, dysglycemia, and a pro-atherogenic plasma lipid profile. MetS creates a high risk for development of type 2 diabetes (T2DM) and cardiovascular disease (CVD), presumably by altering inflammatory responses.
BACKGROUND
Our purpose was to investigate the relationship between oxygen saturation (SpO2) and dynamic interstitial glucose level (IGL) in patients with obstructive sleep apnea (OSA) along with type 2 diabetes mellitus (T2DM), and to investigate the potential mechanisms thereof.
METHODS
A total of
Plasma ATP is a potent vasodilator and is thought to play a role in the local regulation of blood flow. Type 2 diabetes is associated with reduced tissue perfusion. We aimed to examine whether individuals with type 2 diabetes have reduced plasma ATP concentrations compared with healthy
