The root of Pueraria lobata is considered to be a medicinal and edible herb for the treatment of diabetes, and it has a long history of application in China. To explore the constituents responsible for the anti-hyperglycemic activities of P. lobata, a water-soluble polysaccharide (PL70-1-1) was isolated and purified by using a DEAE-Cellulose 52 anion exchange column and a Sephacryl S-100 gel filtration column. Its molecular weight (2584 Da) was determined by high performance gel permeation chromatography (HPGPC)...

Chronic kidney disease (CKD) is a frequent complication of type 2 diabetes mellitus (T2DM) and elevates individuals' risk for cardiovascular disease, the leading cause of morbidity and mortality in T2DM. Achieving and maintaining tight glycemic control is key to preventing development or progression of CKD; however, improving glycemic control may be limited by effects of renal impairment on the efficacy and safety of T2DM treatments, necessitating dosing adjustments and careful evaluation of contraindications...

Estrogen has been implicated in the regulation of growth and immune function in the kidney, which expresses the full-length estrogen receptor α (ERα66), its ERα splice variants, and estrogen receptor β (ERβ). Thus, we hypothesized that these splice variants may inhibit glomerular enlargement that occurs early in type 1 diabetes (T1D). T1D was induced by streptozotocin (STZ) injection in 8-12 wk-old female mice lacking ERα66 (ERα66KO) or all ERα variants (αERKO), and their wild-type (WT) littermates...

REVIEW
Angelo Avogaro, Gian Paolo Fadini
Patients with Type 2 Diabetes have an excess risk for cardiovascular disease. One of the several approaches, included in the Guidelines for the management of Type 2 Diabetes, is based on dipeptidyl peptidase 4 (DPP-4; also termed CD26) inhibitors (DPP-4-I), also called gliptins. Gliptins inhibit the degradation of glucagon-like peptide-1 GLP-1RA: this effect is associated with increased circulating insulin-to-glucagon ratio, and a consequent reduction of HbA1c. Beside incretin hormones, there are several proteins that may be affected by DPP-4 and its inhibition: among these some are relevant for the cardiovascular system homeostasis such as SDF-1α and its receptor CXCR4, brain natriuretic peptides, neuropeptide Y, and peptide YY...

Background: Cardiovascular disease is a major cause of mortality and morbidity in people with type 2 diabetes mellitus (T2DM). Studies have consistently identified dyslipidemia as an important risk factor for the development of macrovascular disease. The landmark United Kingdom Prospective Diabetes Study has shown that metformin therapy reduces cardiovascular events in overweight people with T2DM. This study investigates the effect of metformin monotherapy on serum lipid profile in statin-naïve individuals with newly diagnosed T2DM, and whether the effect, if any, is dosage-related...

Introduction: Maturity onset diabetes of the young due to HNF1A mutations (HNF1A-MODY) is the most frequent form of monogenic diabetes in adults. It is often misdiagnosed as type 1 or type 2 diabetes, but establishing genetic diagnosis is important, as treatment differs from the common types of diabetes. HNF1A-MODY has not been investigated in Croatia before due to limited access to genetic testing. In this study we aimed to describe the characteristics of young adults diagnosed with diabetes before the age of 45 years, who have rare HNF1A allele variants, and estimate the prevalence of HNF1A-MODY in Croatia...

Focus on renewable energy sources and reduced unit costs has led to increased number of wind turbines (WTs). WT noise (WTN) is reported to be highly annoying at levels from 30 to 35 dB and up, whereas for traffic noise people report to be highly annoyed from 40 to 45 dB and up. This has raised concerns as to whether WTN may increase risk for major diseases, as exposure to traffic noise has consistently been associated with increased risk of cardiovascular disease and diabetes. We identified all Danish dwellings within a radius of 20 WT heights and 25% of all dwellings within 20-40 WT heights from a WT...

The failure of insulin production by pancreatic β cells is a common hallmark of type 1 diabetes mellitus (T1DM). Because administration of exogenous insulin is associated with diabetes-derived complications, endogenous α to β cell transition can be an attractive alternative. Although decreased β cell size and hypoinsulinaemia have been observed in S6K1-deficient mice, the molecular mechanism underlying the involvement of S6K1 in the transcriptional regulation of insulin remains elusive. Here, we show that the hypoinsulinaemic phenotype of S6K1-deficient mice stems from the dysregulated transcription of a set of genes required for insulin and glucagon production...

We aimed to examine the association between parental occupational social contact and hygiene factors on type 1 diabetes (T1D) risk and possible mediation of these effects through child enteroviral infection. We interviewed 333 incident T1D cases and 660 controls from 2008-2011 in Melbourne, Australia. Enteroviral indices (ribonucleic acid by reverse transcription polymerase chain reaction and Coxsackie B virus antibody levels) in peripheral blood were measured in nested case control samples. Parent occupational social contact was assessed by the number of well or sick children, adults or animals contacted daily through work...

Metformin is widely used for the management of type 2 diabetes mellitus (T2DM). Recently growing evidence has shown its anti-cancer effects. The results are mainly obtained from observational studies and thus, little information is available concerning the mechanisms of action. Adenosine monophosphate (AMP)-activated protein kinase (AMPK) plays an important role in the mechanism of action of metformin. The anti-cancer mechanisms of metformin include direct and indirect effects. The direct effects of metformin include AMPK-independent and AMPK-dependent effects, whereas the decrease in glucose level, hyperinsulinemia, and Insulin-like growth factor 1 (IGF-1) level was considered its indirect effects...
