Diabetic cardiomyopathy is a major and severe cardiovascular complication of diabetes mellitus. Ursolic acid, a pentacyclic triterpene compound widespread in fruits and plants, performs a variety of pharmacological activities including lowering blood glucose, anti-oxidation, anti-inflammation and anti-fibrosis. Our present study aimed to investigate the cardioprotective effects of ursolic acid on diabetic cardiomyopathy rats and uncover its underlying mechanism. Diabetes mellitus was induced by a single injection of STZ-only (40 mg/ kg, i...

BACKGROUND: A longitudinal study assessed serum paraoxonase 1 (PON1) activity and concentration as affected by age and as associated with the development of type 2 diabetes (T2D). PON1's recently established physiological function is the hydrolysis of lipolactones in oxidized LDL particles. METHODS: Serum samples and clinical data collected and stored at different time points over a 20 year interval in the Air Force Health Study were analyzed. PON1 activity and concentration and C-reactive protein (CRP) concentration in samples from the same individuals 20 years apart were compared using a paired t test (n=159)...

The human retina is composed of the sensory neuroretina and the underlying retinal pigmented epithelium (RPE), which is firmly complexed to the vascular choroid layer. Different regions of the retina are anatomically and molecularly distinct, facilitating unique functions and demonstrating differential susceptibility to disease. Proteomic analysis of each of these regions and layers can provide vital insights into the molecular process of many diseases, including Age-Related Macular Degeneration (AMD), diabetes mellitus, and glaucoma...

The global burden of chronic kidney disease (CKD) has increased substantially in recent years, partly attributed to the global epidemic of diabetes mellitus. In many countries including China, glomerulonephritis was the most common cause of end stage renal disease (ESRD). The mortality rate of dialysis patients can be as high as patients with colon, breast and prostate cancers. CKD has important socio-economic impact on the healthcare system and society. Increasing awareness and early detection of CKD cannot be overemphasized...

As an important complication of diabetic mellitus, diabetic kidney disease (DKD) is becoming a major cause of morbidity and mortality worldwide. Given the diminished quality of life and the economic cost, identification of the risk factors for DKD and initiation of in-time therapies are of great importance. The initiators of DKD include hyperglycemia and predisposing genes, while the promotors of DKD include hyperglycemia, albuminuria, hypertension, dyslipdemia, insulin resistance, anemia, long duration of diabetes, smoking, ethnicity, westernization, sex, age, and so on...

Lenalidomide is commonly used for multiple myeloma as either induction or maintenance therapy. The agent is associated with a host of adverse effects, but hypoglycemia has only been reported in one phase I trial in patients with solid tumors. We describe a 74-year-old woman who experienced grade 3 hypoglycemia (blood glucose level 35 mg/dL) likely related to lenalidomide. Her medical history was significant for refractory myeloma and type 2 diabetes mellitus. Lenalidomide was started as maintenance therapy following autologous bone marrow transplantation...

Polycystic ovary syndrome (PCOS) is a very prevalent endocrine disease affecting reproductive women. Clinically, patients with this disorder are more vulnerable to develop type 2 diabetes mellitus (T2DM), cardiovascular events, as well as metabolic syndrome (MetS). To date, the molecular mechanism underlying PCOS remains largely unknown. Previously, we showed that mitochondrial dysfunction caused by mitochondrial DNA (mtDNA) mutation was an important cause for PCOS. In the current study, we described the clinical and biochemical features of a three-generation pedigree with maternally transmitted MetS, combined with PCOS...

Gestational diabetes mellitus (GDM) characterizes by foetoplacental endothelial dysfunction. Human umbilical vein endothelial cells (HUVECs) from women with GDM show increased L-arginine transport via the human cationic amino acid transporter 1 (hCAT-1). Moreover, expression of endothelial nitric oxide synthase (eNOS) and nitric oxide synthesis are increased. Exosomes are increased in maternal plasma from GDM. We evaluated the role of foetoplacental endothelial exosomes on endothelial dysfunction in GDM. Exosomes were isolated from HUVECs from normal (ExN) and GDM (ExGDM) pregnancies...

AIMS: Glucagon-like peptide-1 (GLP-1) contributes to insulin secretion after meals. Though Hispanics have increased risk for type 2 diabetes mellitus, it is unknown if impaired GLP-1 secretion contributes to this risk. We therefore studied plasma GLP-1 secretion and action in Hispanic adults. METHODS: Hispanic (H; n=31) and non-Hispanic (nH; n=15) participants underwent an oral glucose tolerance test (OGTT). All participants were categorized by glucose tolerance into four groups: normal glucose tolerant non-Hispanic (NGT-nH; n = 15), normal glucose tolerant Hispanic (NGT-H; n = 12), impaired glucose tolerant Hispanic (IGT-H; n = 11), or newly diagnosed type 2 diabetes mellitus, Hispanic (T2D-H; n = 8)...

Small fiber neuropathy, which affects the sensory A≏ and C fibers, is now a major diagnostic and therapeutic challenge. Nearly 7% of the general population have chronic neuropathic pain responsible for severe quality-of-life impairments. Awareness must therefore be raised among clinicians of the somatosensory and autonomic symptoms that can reveal small fiber neuropathy, appropriate diagnostic investigations, most common causes, and best treatment options for each patient profile. To help achieve this goal, the present review article discusses the clinical presentation of neuropathic pain and paresthesia and/or autonomic dysfunction due to involvement of nerves supplying exocrine glands and smooth muscle; normal findings from standard electrophysiological investigations; most informative diagnostic tests (epidermal nerve fiber density in a skin biopsy, laser-evoked potentials, heat- and cold-detection thresholds, electrochemical skin conductance); main causes, which consist chiefly of metabolic diseases (diabetes mellitus, glucose intolerance), dysimmunity syndromes (Sjögren's syndrome, sarcoidosis, monoclonal gammopathy), and genetic abnormalities (familial amyloidosis due to a transthyretin mutation, Fabry disease, sodium channel diseases); and the available symptomatic and etiological treatments...

The World Health Organisation recommends exclusive breastfeeding for the first six months of life ([1]. Breastfeeding confers many short- and long-term benefits for infants and mothers, including reduced childhood obesity and lower maternal body weight [2-6]. Exclusive breastfeeding is also recommended in women with type 1 diabetes mellitus (T1DM), for at least four months [7]. However, the impact of breastfeeding on mothers with T1DM, and, conversely, the impact of maternal T1DM on breastfeeding, is not clear...

In view of the pathologic basis for the treatment of diabetic neuropathy, it is important to enhance nerve regeneration as well as prevent nerve degeneration. So, in the present study, we have investigated the effect of S-Methylisothiourea Sulfate (selective iNOS inhibitor) and Citicoline, alone and in combination, on Type II Diabetes Mellitus induced neuropathic pain in wistar rats. Type II diabetes was induced by providing high fat diet and low dose of Streptozotocin for 35 days in rats. Type II Diabetes Mellitus was assessed in terms of increased glucose, triglycerides, cholesterol, LDL levels, glucose tolerance and decrease in HDL levels...
