In vivo confocal microscopy (IVCM) is becoming an indispensable tool for studying corneal physiology and disease. Enabling the dissection of corneal architecture at a cellular level, this technique offers fast and noninvasive in vivo imaging of the cornea with images comparable to that of ex vivo histochemical techniques. Corneal nerves bear substantial relevance to clinicians and scientists alike, given their pivotal roles in regulation of corneal sensation, maintenance of epithelial integrity, and proliferation and promotion of wound healing...

INTRODUCTION: Diabetic erectile dysfunction is a disease mostly of vascular origin and men with diabetic erectile dysfunction respond poorly to oral phosphodiesterase-5 inhibitors. Hepatocyte growth factor (HGF) is a pleiotropic factor that plays an essential role in the regulation of cell proliferation, survival, and angiogenesis. AIM: To determine the effectiveness of recombinant human (rh)-HGF in restoring erectile function in diabetic mice. METHODS: Four groups of mice were used: control non-diabetic mice and streptozotocin-induced diabetic mice receiving two successive intracavernous injections of phosphate buffered saline (days -3 and 0), a single intracavernous injection of rh-HGF (day 0), or two successive intracavernous injections of rh-HGF (days -3 and 0)...

BACKGROUND: Bogijetong decoction (BGJTD) is a herbal drug formulation used in the traditional Asian medicine to treat neuropathic insults associated with diabetes and anticancer therapy. To understand the biological basis of BGJTD on protective effects against neuropathy, we investigated physiological and biochemical responses of the sciatic nerves deranged by taxol injection or crush injury in the rats. METHODS: Dissociated Schwann cells and neurons were prepared from the sciatic nerve and dorsal root ganglia (DRG) respectively and were treated with taxol and BGJTD...

Visual function has been shown to deteriorate prior to the onset of retinopathy in some diabetic patients and experimental animal models. This suggests the involvement of the brain's visual system in the early stages of diabetes. In this study, we tested this hypothesis by examining the integrity of the visual pathway in a diabetic rat model using in vivo multi-modal magnetic resonance imaging (MRI). Ten-week-old Sprague-Dawley rats were divided into an experimental diabetic group by intraperitoneal injection of 65 mg/kg streptozotocin in 0...

Diabetic retinopathy is a progressive microvascular disease that leads to increased vessel permeability, retinal ischemia, and retinal neovascularization. Optical coherence tomography angiography (OCTA) is a novel angiography technique that has the capability to advance our understanding of diabetic eye disease by providing high-resolution images of retinal and choroidal microvasculature blood flow and structure. Using OCTA, the vascular changes of diabetic retinopathy including microaneurysms, retinal non-perfusion, intraretinal microvascular abnormalities, and neovascularization can be clearly visualized...

The data described in this article is related to the review article "Medicinal plants used in the traditional management of diabetes and its sequelae in Central America: a review" (Giovannini et al., 2016) [1]. We searched publications on the useful plants of Central America in databases and journals by using selected relevant keywords. We then extracted reported uses of medicinal plants within the disease categories: diabetes mellitus, kidney disease, urinary problems, skin diseases and infections, cardiovascular disease, sexual dysfunction, vision loss, and nerve damage...

Although diabetic peripheral neuropathy (DPN) and chemotherapy-induced peripheral neuropathy (CIPN) are different disease entities, they share similar neuropathic symptoms that impede quality of life for these patients. Despite having very similar downstream effects, there have been no direct comparisons between DPN and CIPN with respect to symptom severity and therapeutic responses. We compared peripheral nerve damage due to hyperglycemia with that caused by paclitaxel (PAC) treatment as represented by biochemical parameters, diverse sensory tests, and immunohistochemistry of cutaneous and sciatic nerves...

Hypertension (HTN) is the most prevalent modifiable risk for cardiovascular disease (CVD) and disorders directly influencing CVD (i.e. obesity, diabetes, chronic kidney disease, obstructive sleep apnea, etc.). About one billion people worldwide have HTN, with American adults having 90% lifetime risk of developing HTN. Despite aggressive campaign for lifestyle changes and advances in drug therapy, HTN remains an immense health, emotional, and economic challenge. This is due, in part, to the fact that ∼50% of HTN patients' blood pressure remains uncontrolled and ∼20% of HTN patients are resistant to or require > antihypertensive drugs...

OBJECTIVE: Renal denervation (RDN) lowers blood pressure (BP) by interruption of sympathetic nerve activity. A high sympathetic tone increases not only BP but also decreases pancreatic beta cell insulin secretion. Hence, the objective of the study was to analyze whether RDN improves secretory capacity of beta cells. DESIGN AND METHOD: In 40 patients (7 diabetics, 19 prediabetics, 14 non diabetics) with treatment resistant hypertension (defined by office BP ≥ 140/90 mmHg and diagnosis confirmed with 24-h ambulatory BP ≥ 130/80 mmHg), insulin secretion was measured before and 6 months after RDN (Simplicity flex catheter, Medtronic) by glucagon test...

There is now a considerable body of evidence to suggest that the fat cells that surround blood vessels (perivascular adipose tissue, PVAT) can influence profoundly arterial tone by releasing vasodilator adipokines which can act locally in a paracrine fashion. In healthy lean individuals the primary vasodilator released appears to be adiponectin and there is a complex interation between autonomic nerve firing in PVAT and the release of nitric oxide from adipocytes and an increased bioavailability of adiponectin...

Double crush syndrome (DCS), as it is classically defined, is a clinical condition composed of neurological dysfunction due to compressive pathology at multiple sites along a single peripheral nerve. The traditional definition of DCS is narrow in scope because many systemic pathologic processes, such as diabetes mellitus, drug-induced neuropathy, vascular disease and autoimmune neuronal damage, can have deleterious effects on nerve function. Multifocal neuropathy is a more appropriate term describing the multiple etiologies (including compressive lesions) that may synergistically contribute to nerve dysfunction and clinical symptoms...

Reported rates of venous thromboembolism (VTE) after shoulder arthroplasty (SA) range from 0.2% to 13%. Few studies have evaluated the incidence of VTE in a large patient population from a single institution. We conducted a study to determine the incidence of VTE (deep venous thrombosis [DVT] and pulmonary embolism [PE]) in a large series of SAs. Cases of SAs performed at our institution between January 1999 and May 2012 were retrospectively reviewed for development of symptomatic VTE within the first 90 days after surgery...

Hypertension is one of the most common conditions seen in primary care and a major public health problem in India. It can lead to various complications if not detected early and treated appropriately. As per the latest Eighth Joint National Committee (JNC 8) the goal BP in most hypertensive patients age <60 years should be <140/90 mmHg and treatment can be started by selecting drugs from among 4 specific medication classes i.e. angiotensin converting enzyme inhibitor (ACEI) or angiotensin receptor blocker (ARB), calcium channel blocker (CCB) or diuretics...
