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...

Surgical correction of complex foot and ankle deformities secondary to Charcot neuroarthropathy remains a significant surgical challenge. New technological advancements in hardware have allowed for the use of augmented fixation techniques in midfoot deformity correction, including the use of indication-specific locking plates and beaming techniques that offer enhanced stability. Severe hindfoot deformity management can employ the use of internal fixation, including intramedullary hindfoot nails and circular external fixation frames for limb salvage...

REVIEW
Bryon McKenna, N Jake Summers
Amnion and amniotic tissue has been studied for more than 100 years in the treatment of acute and chronic wounds. Recent studies have focused on the use of amnion tissue in the management of full-thickness diabetic wounds, particularly of the lower extremities. With new harvesting, processing, and distribution technologies, amnion is increasingly available in treating these wounds. Current data and research show increased healing potential and decreased healing times, pain, drainage, and infection in wounds treated with amnion products...

Small molecule mitohondrial uncouplers transport protons from the mitochondrial inner membrane space into the mitochondrial matrix independent of ATP synthase, uncoupling nutrient metabolism from ATP generation. The therapeutic potential of mitochondrial uncouplers have been investigated for the treatment metabolic diseases such as obesity and type 2 diabetes (T2D), as well as for neurodegenerative diseases including Alzheimer's disease and Parkinson's disease. This perspective will review the mitochondrial uncouplers reported to date and explore their potential as therapeutics...

Insulin-like growth factor 1 (IGF-1) influences cell proliferation and survival. In the extracellular environment, IGF-1 circulates bound to proteins (IGF-binding proteins; IGFBP), some of which have physiological effects that seem independent of IGF-1, including the brain (for example, IGFBP-3). We completed a systematic review of the association between dementia and IGF-1 and IGFBP-3, and a cross-sectional and longitudinal study designed to investigate if lower plasma concentration of these proteins increased the risk of prevalent and incident dementia...

Nerve conduction block with a high intensity-focused ultrasound (HIFU) transducer has been performed in normal and diabetic animal models recently. HIFU can reversibly block the conduction of peripheral nerves without damaging the nerves while using an appropriate ultrasonic parameter. Temporary and partial block of the action potentials of nerves shows that HIFU has the potential to be a useful clinical treatment for pain relief. This work demonstrates the procedures for suppressing the action potentials of neuropathic nerves in diabetic rats in vivo using an HIFU transducer...

Hua Yu, Ricardo Paiva, Richard A Flavell
Type 1 diabetes (T1D) is a T cell-mediated autoimmune disease resulting in islet β-cell destruction, hypoinsulinemia, and severely altered glucose homeostasis. Although the mechanisms that initiate T1D still remain elusive, a breakdown of immune tolerance between effector T cells (Teff) and regulatory T cells (Treg) is considered to be the crucial component leading to autoimmunity. As such, strategies have been developed to boost the number and/or function of Treg in the hope of specifically hampering the pathogenic Teff activity...

AIMS: Inflammation is strongly associated with the mechanisms of β-cell failure in type 2 diabetes. Blockade of the key proinflammatory cytokine IL-1β has been implicated as a promising therapeutic strategy for the prevention and treatment of type 2 diabetes. In this study, we developed an IL-1β-targeted therapeutic vaccine consisting of an IL-1β epitope peptide (A1β) and assessed its efficacy on a diabetic KK-A(y) mouse model. MAIN METHODS: KK-A(y) mice were immunized with A1β for three injections at a 2-week interval...

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)...

There is a critical need for new mechanism-of-action drugs that reduce the burden of obesity and associated chronic metabolic comorbidities. A potentially novel target to treat obesity and type 2 diabetes is nicotinamide-N-methyltransferase (NNMT), a cytosolic enzyme with newly identified roles in cellular metabolism and energy homeostasis. To validate NNMT as an anti-obesity drug target, we investigated the permeability, selectivity, mechanistic, and physiological properties of a series of small molecule NNMT inhibitors...

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...

Diabetic kidney disease and atherosclerotic disease are major causes of morbidity and mortality associated with type 2 diabetes (T2D), and diabetic kidney disease is a major cardiovascular risk factor. The BTBR mouse strain with leptin-deficiency (Lep(ob)) has emerged as one of the best models of human diabetic kidney disease. However, no T2D mouse model of combined diabetic kidney disease and atherosclerosis exists. Our goal was to generate such a model. To this end, the LDL receptor was targeted for degradation via IDOL (inducible degrader of the LDL receptor) overexpression, using a liver-targeted adeno-associated virus (AAV-DJ/8) in BTBR wild-type (WT) and BTBR Lep(ob) (OB) mice...
