Defocused low-energy shock wave (DLSW) has been shown effects on activating mesenchymal stromal cells (MSCs) in vitro. In this study, recruitment of endogenous stem cells was firstly examined as an important pathway during the healing process of diabetic bladder dysfunction (DBD) treated by DLSW in vivo. Neonatal rats received intraperitoneal injection of 5-ethynyl-2-deoxyuridine (EdU) and then DBD rat model was created by injecting streptozotocin. Four weeks later, DLSW treatment was performed. Afterward, their tissues were examined by histology...

BACKGROUND: Diabetic hyperglycemia damages peripheral nerves by triggering ischemia, oxidative stress, and inflammation. Alpha-lipoic acid (ALA) and methylcobalamin (MC) are known to improve signs of diabetic peripheral neuropathy (DPN), possibly by enhancing neural and vascular endothelial cell metabolism and antioxidant capacity. We evaluated differences in efficacy following short-term MC or ALA treatment on DPN symptoms to guide clinical drug selection. METHODS: Forty DPN patients were randomly divided into MC and ALA treatment groups (n=20/20) and assessed by the Toronto Clinical Neuropathy Scoring System (TCSS), total symptom score (TSS), visual analog scale (VAS) of positive symptoms, and easy sensory test (EST) for negative symptoms before and after 2 weeks of treatment...

BACKGROUND: Reports on alterations in somatic neural functions due to non-diabetic obesity, a major risk factor for diabetes, are few and still a matter of debate. Nevertheless, to our knowledge, reports lack any comments on the type of somatic nerve fibers affected in non-diabetic obesity. Therefore, this study aimed to find out the alteration in somatic neural functions in non-diabetic obese persons if any. METHODS: The study was conducted on 30 adult non-diabetic obese persons (mean age 32...

BACKGROUND: Soya supplements are used in the treatment of neuropathic pain. Previous reports reveal that consumption of soy diet before nerve injury prevents the development of neuropathic pain in rats. Biochanin-A, a soy isoflavone, has a naturally occurring inhibitor of fatty acid amide hydrolase (FAAH) that metabolized endocannabinoids. OBJECTIVE: The objective was to evaluate efficacy of biochanin-A in streptozotocin (STZ) induced neuropathic pain in rat model...

BACKGROUND: Although many factors have been found to be involved in recovery from Bell's palsy, no study has investigated the association between recovery from Bell's palsy and obesity. This study therefore evaluated the association between recovery from Bell's palsy and body mass index (BMI). METHODS: Subjects were classified into five groups based on BMI (kg/m2). Demographic and clinical characteristics were compared among these groups. Assessed factors included sex, age, time from paralysis to visiting a hospital, presence of comorbidities such as diabetes mellitus and hypertension, degree of initial facial nerve paralysis by House-Brackmann (H-B) grade and neurophysiological testing, and final recovery rate...

1-Deoxysphingolipids (deoxySLs) are atypical sphingolipids that are elevated in the plasma of patients with type 2 diabetes and hereditary sensory and autonomic neuropathy type 1 (HSAN1). Clinically, diabetic neuropathy and HSAN1 are very similar, suggesting the involvement of deoxySLs in the pathology of both diseases. However, very little is known about the biology of these lipids and the underlying pathomechanism. We synthesized an alkyne analogue of 1-deoxysphinganine (doxSA), the metabolic precursor of all deoxySLs, to trace the metabolism and localization of deoxySLs...

Perineural catheter infection is a rare but potentially dramatic complication of continuous peripheral nerve block. Different risk factors have been identified and the incidence of infection is increased in trauma victims, intensive care unit patients, immunodeficient individuals, and diabetic patients. Also, postoperative hyperglycemia, the absence of antibiotic prophylaxis, and catheter lasting more than 48 hours seem to be associated with a greater risk of infection. Skin disinfection and a strict aseptic technique during catheter placement are fundamental...

Streptozotocin (STZ)-induced chronic hyperglycemia has a detrimental effect on neurovascular coupling, linked to increased PKC-mediated phosphorylation and PKC isoform expression changes. Here, we sought to determine whether: 1) selective PKC-α/β/γ inhibitor, GF109203X, could reverse the effects of chronic hyperglycemia on cerebrovascular reactivity; 2) pancreatic islet transplantation could prevent the development of cerebrovascular impairment seen in a rat model of Type 1 Diabetes. We studied the effect of GF109203X in diabetic (DM), non-diabetic (ND), and transplanted (TR) Lewis rats during either sciatic nerve stimulation (SNS) or the topical applications of the large-conductance Ca(2+)-operated K(+) (BKCa) channel opener, NS1619, or the K(+) inward rectifier (Kir) channel agonist, KCl...

Overfeeding of fat can cause various metabolic disorders including obesity and type 2 diabetes (T2D). Diet provided free fatty acids (FFAs) are not only essential nutrients, but they are also recognized as signaling molecules, which stimulate various important biological functions. Recently, several G protein-coupled receptors (GPCRs), including FFA1-4, have been identified as receptors of FFAs by various physiological and pharmacological studies. FFAs exert physiological functions through these FFA receptors (FFARs) depending on carbon chain length and degree of unsaturation...

: : Triple decompression surgery has been advocated as a treatment for diabetic peripheral neuropathy (DPN). A practice advisory published in 2006 by the American Academy of Neurology concluded that "this treatment alternative should be considered unproven." Since then, multiple cohort studies involving several thousands of patients and 1 nonblind, randomized, controlled trial have been published, suggesting that surgical treatment of DPN has become commonplace in many centers globally...
