Otilonium bromide (OB) is a spasmolytic drug successfully used for the treatment of irritable bowel syndrome (IBS). Its efficacy has been attributed to the block of L- and T-type Ca2+ channels and muscarinic and tachykinin receptors in the smooth muscle. Furthermore, in healthy rats, repeated OB administration modified neurotransmitter expression and function suggesting other mechanisms of acti...

In recent years, new and effective therapeutic agents for blood glucose control have been added to standard diabetes therapies: dipeptidyl peptidase-4 (DPP-4) inhibitors, which prolong the bioavailability of the endogenously secreted incretin hormone glucagon-like peptide-1 (GLP-1). Full-thickness excisional wounding was performed in wild-type (C57BL/6J) and diabetic [C57BL/6J-obese/obese (ob/o...

Introduction: The accumulation of lipid in non-adipose tissue closely relates to insulin resistance (IR) in type 2 diabetic [1]. The relationship between intramyocellular lipid (IMCL) levels and IR is not fully understood though a link to obesity as risk factor is established. Mouse models of diabetes/obesity are attractive tools for mechanistic studies. In this study, intramyocellular lipid (I...

Chronic inflammation has been postulated to play an important role in the pathogenesis of insulin resistance. Inducible nitric oxide synthase (iNOS) has been implicated in many human diseases associated with inflammation. iNOS deficiency was shown to prevent high-fat diet-induced insulin resistance in skeletal muscle but not in the liver. A role for iNOS in fasting hyperglycemia and hepatic ins...

No any effective treatments can prevent from the motor neuron degeneration in amyotrophic lateral sclerosis (ALS) at present. In order to modulating the endogenous neural precursor cells (NPCs) to repairing the degenerative motor neurons in ALS, we studied the alteration of endogenous vimentin-containing NPCs in olfactory bulb (OB) at the different stages of SOD1 wlid-type and G93A transgenic m...

The mammalian olfactory bulb (OB) displays robust activity-dependent plasticity throughout life. Dopaminergic (DA) neurons in the glomerular layer (GL) of the OB are particularly plastic, with loss of sensory input rapidly reducing tyrosine hydroxylase (TH) expression and dopamine production, followed by a substantial reduction in DA neuron number. Here, we asked whether microglia participate i...

OBJECTIVE Accumulating evidence indicates that the regimen to increase adiponectin will provide a novel therapeutic strategy for metabolic syndrome. Here, we tested the effect of a potent and selective peroxisome proliferator-activated receptor-γ agonist, rivoglitazone (Rivo), a newly synthesized thiazolidinedione derivative, on adiponectin, insulin resistance, and atherosclerosis. METHODS AN...

Energy expenditure in ob/ob mice kept at thermoneutrality was quantified from food intake and body composition of mice treated with leptin over 15 and 75 days, respectively. Energy expenditure in response to 15 days of treatment with leptin was twice as high as under pair-feeding conditions, indicating extensive breakdown of adipose tissue independent of a centrally mediated satiation. Leptin-i...
