PURPOSE: Mirabegron (β3-adrenoreceptor agonist) is a new molecule with a distinct mechanism of action from antimuscarinics. Combination therapy with solifenacin was recently studied in adult population. Our objective was to evaluate the efficacy and safety of mirabegron as add-on therapy, to treat urinary incontinence in children with idiopathic OAB, refractory/intolerant to antimuscarinics. MATERIALS AND METHODS: A prospective off-label study using add-on regimens of mirabegron was conducted with pediatric patients presenting no symptom improvement under intensive behavioural and medical therapies and/or significant side effects (S/E) on antimuscarinic dose escalation...

Our previous findings clearly suggested the role of duration of exposure to monocrotophos (MCP) in the development of insulin resistance. Rats exposed chronically to MCP developed insulin resistance with hyperinsulinemia without overt diabetes. In continuation of this vital observation, we sought to delineate the biochemical mechanisms that mediate heightened pancreatic β-cell response in the wake of MCP-induced insulin resistance in rats. Adult rats were orally administered (0.9 and 1.8mg/kgb.w/d) MCP for 180days...

BACKGROUND AND OBJECTIVES: Adolescence-related increases in both anxiety and risk taking may originate in variability in Intolerance of Uncertainty (IU), rendering the study of IU of importance. We therefore studied the psychometric properties of the Intolerance of Uncertainty Scale-Short version (IUS-12), including its associations with trait anxiety and risk taking, among adolescents. METHODS: A sample of 879 Dutch adolescents, from diverse educational levels, and with an equal distribution of boys and girls, was classically tested...

Multiple tyrosine kinase inhibitors (TKIs) are available for managing patients with chronic myeloid leukemia. Although most patients have a favorable outcome with their initial therapy, whether imatinib or a second-generation TKI was used, some will require subsequent use of one or more different TKIs. Such sequencing might be indicated in a reactive way (ie, for patients who have experienced resistance or intolerance to their initial therapy) or in a proactive way (ie, for patients with a somewhat favorable outcome who have not reached an "optimal" outcome)...

A 10-year old Lhasa Apso dog was presented for an acute history of exercise intolerance and hind limb weakness. High grade second degree atrioventricular block with an atrial rate of 200 beats per minute, ventricular rate of 40 beats per minute and an intermittent ventricular escape rhythm, was diagnosed on electrocardiograph. A transdiaphragmatic, unipolar, epicardial pacemaker was implanted without immediate surgical complications. Severe vomiting was noted 12 h post-operatively. Abdominal ultrasound and a barium study supported a diagnosis of pyloric outflow obstruction and exploratory abdominal surgery was performed...

Copper is a required metal nutrient for life, but global or local alterations in its homeostasis are linked to diseases spanning genetic and metabolic disorders to cancer and neurodegeneration. Technologies that enable longitudinal in vivo monitoring of dynamic copper pools can help meet the need to study the complex interplay between copper status, health, and disease in the same living organism over time. Here, we present the synthesis, characterization, and in vivo imaging applications of Copper-Caged Luciferin-1 (CCL-1), a bioluminescent reporter for tissue-specific copper visualization in living animals...

Obesity is an alarming global health problem that results in multiaspect metabolic syndromes in both genders and most age groups. The lack of effective therapies for obesity and its associated metabolic syndrome is an urgent societal issue. To elucidate whether mesenchymal stromal cell (MSC)-based therapies can ameliorate high-fat diet-induced obesity and compare the effectiveness of several methodological approaches, we transplanted human MSCs, MSC-derived brown adipocytes (M-BA), and MSC lysateinto obese mice...

BACKGROUND: Pb (lead) exposure occurs at elevated frequency in urban inner city populations that also have high rates of obesity and diabetes. OBJECTIVES: To determine if Pb can promote the development of diabetes in a setting of obesity, we examined the effect of Pb exposure on glucose metabolism in a rodent model of obesity. METHODS: Adult female ZDF rats were exposed to Pb in drinking water for 24 weeks. Fasting blood glucose, insulin, and glucose tolerance were measured at regular intervals...

Iodine consumption in excess of its recommended levels over a prolonged period of time is well known to cause thyroid disorders. The thyroid hormones on the other hand are responsible in maintenance of the physiology of the reproductive system. Excess iodine intake affects male reproductive physiology. However, the effects of excess iodine on the ovarian structure and function is yet to be established. The present study has thus been undertaken to investigate the effect of excess iodine on the ovarian physiology...

Intolerance of Uncertainty (IU), defined as the dispositional interpretation of uncertain or ambiguous events as stressful and problematic, has been linked to excessive worry and other anxiety-related problems in adults and youth. IU has been conceptualized as a vulnerability factor for excessive worry and anxiety, but the historical absence of a supported measure of IU in young children has hampered longitudinal research needed to evaluate temporal relationships between IU and anxiety and the differential developmental pathways of IU leading to different anxiety disorders and depression...

Many studies have investigated the effect of crude tomato peel in vivo, but no studies have determined the dose-effect of dry tomato peel (DTP) on glucose intolerance, insulin resistance, and atherogenic dyslipidemia induced by a high-saturated-fat (HSF) diet in vivo. The aim of this study was to investigate the effects of different doses of DTP on the levels of oxidative stress in mice fed an HSF and cholesterol-rich diet for 12 weeks. The main outcomes are glucose and insulin tolerance, plasma lipids, and hepatic steatosis and inflammation...

BACKGROUND: The mammalian target of rapamycin complex 1 (mTORC1) is a central node in a network of signaling pathways controlling cell growth and survival. This multiprotein complex integrates external signals and affects different nutrient pathways in various organs. However, it is not clear how alterations of mTORC1 signaling in skeletal muscle affect whole-body metabolism. RESULTS: We characterized the metabolic phenotype of young and old raptor muscle knock-out (RAmKO) and TSC1 muscle knock-out (TSCmKO) mice, where mTORC1 activity in skeletal muscle is inhibited or constitutively activated, respectively...

BACKGROUND: Diabetes is the seventh leading cause of death in the USA, and disruption of circadian rhythms is gaining recognition as a contributing factor to disease prevalence. This disease is characterized by hyperglycemia and glucose intolerance and symptoms caused by failure to produce and/or respond to insulin. The skeletal muscle is a key insulin-sensitive metabolic tissue, taking up ~80 % of postprandial glucose. To address the role of the skeletal muscle molecular clock to insulin sensitivity and glucose tolerance, we generated an inducible skeletal muscle-specific Bmal1 (-/-) mouse (iMSBmal1 (-/-))...

BACKGROUND: Recurrent hepatocellular carcinoma after a patient's initial therapy, whether it is transplantation, resection, or ablation, remains a challenging clinical problem. Since recurrence occurs in 70% of all initially treated disease within 5 years, optimal management to treat this recurrence is needed. Currently, a bias exists toward mono-therapy (i.e., ablation alone, hepatic arterial therapy alone, or sorafenib therapy alone) instead of concurrent sequential therapy-as is common in other primary and metastatic disease to the liver...

The purpose of cardiopulmonary exercise testing (CPET) in the obese person, as in any cardiopulmonary exercise test, is to determine the patient's exercise tolerance, and to help identify and/or distinguish between the various physiological factors that could contribute to exercise intolerance. Unexplained dyspnoea on exertion is a common reason for CPET, but it is an extremely complex symptom to explain. Sometimes obesity is the simple answer by elimination of other possibilities. Thus, distinguishing among multiple clinical causes for exertional dyspnoea depends on the ability to eliminate possibilities while recognising response patterns that are unique to the obese patient...

Approximately 33% of chronic myeloid leukemia (CML) patients discontinue treatment with imatinib in the long-term due to resistance and/or intolerance. Second-generation tyrosine kinase inhibitors (TKIs) (dasatinib, nilotinib, bosutinib) and third-generation (ponatinib) have added complexity to the treatment paradigm for this disease. Areas covered: Second generation TKIs, approved as second-line treatment in all phases of the disease, are highly effective in patients resistant to and/or intolerant to imatinib and are extremely active against all the resistant BCR-ABL1 mutations, with the exception of T3151...

This study describes a 13-yr-old girl with orthostatic intolerance, respiratory weakness, multiple endocrine abnormalities, pancreatic insufficiency, and multiorgan failure involving the gut and bladder. Exome sequencing revealed a de novo, loss-of-function allele in SLC12A2, the gene encoding the Na-K-2Cl cotransporter-1. The 11-bp deletion in exon 22 results in frameshift (p.Val1026Phefs*2) and truncation of the carboxy-terminal tail of the cotransporter. Preliminary studies in heterologous expression systems demonstrate that the mutation leads to a nonfunctional transporter, which is expressed and trafficked to the plasma membrane alongside wild-type NKCC1...

OBJECTIVE: Adipose tissue relies on lipid droplet (LD) proteins in its role as a lipid-storing endocrine organ that controls whole body metabolism. Hypoxia-inducible Gene 2 (Hig2) is a recently identified LD-associated protein in hepatocytes that promotes hepatic lipid storage, but its role in the adipocyte had not been investigated. Here we tested the hypothesis that Hig2 localization to LDs in adipocytes promotes adipose tissue lipid deposition and systemic glucose homeostasis. METHOD: White and brown adipocyte-deficient (Hig2(fl/fl) × Adiponection cre+) and selective brown/beige adipocyte-deficient (Hig2(fl/fl) × Ucp1 cre+) mice were generated to investigate the role of Hig2 in adipose depots...
