OBJECTIVES: High-fat high-sucrose diet (HFHS) overfeeding is one of the main factors responsible for the increased prevalence of metabolic disorders. Elevated levels of branched-chain amino acids (BCAAs) have been associated with metabolic dysfunctions, including insulin resistance (IR). The aim of this study was to elucidate whether elevated BCAA levels are the cause or the consequence of IR and to determine the mechanisms and tissues involved in such a phenotype. METHODS: We performed a 2-mo follow-up on minipigs overfed an HFHS diet and focused on kinetics fasting and postprandial (PP) BCAA levels and BCAA catabolism in key tissues...

Obesity and associated metabolic co-morbidities are a worldwide public health problem. Negative health outcomes associated with obesity, however, do not arise from excessive adiposity alone. Rather, deleterious outcomes of adipose tissue accumulation are a result of how adipocytes are distributed to individual regions in the body. Due to our increased understanding of the dynamic relationship that exists between specific adipose depots and disease risk, an accurate characterization of total body adiposity as well as location is required to properly evaluate a population's disease risk...

Background Severe mental illnesses (SMIs), i.e. major depression, schizophrenia and bipolar disorder, are associated with an elevated risk for the development of type-2 diabetes mellitus and cardiovascular disorders. Several factors have been associated with increased cardiometabolic morbidity and mortality in SMI, including lifestyle factors (smoking, inactivity, unhealthy diet), endocrine and immunologic alterations; however, the underlying mechanisms remain to be fully uncovered. It is now well accepted that visceral adipose tissue (VAT) promotes the development of cardiometabolic disorders, at least in part by inflammatory and metabolic functions...

Adipose tissue exists in many locations or depots that differ from one another based on numerous and various characteristics. The unique "layered" anatomical feature of subcutaneous adipose tissue (SAT) in man and the pig is reviewed and discussed. The origin of fetal pig adipose tissue subcutaneous layers is reviewed before the onset of adipogenesis and after the overt adipogenesis. Furthermore, the distinguishing characteristics of developing outer SAT layer (OSQ) and middle SAT layer (MSQ) in pigs are reviewed...

OBJECTIVE: Visceral adiposity index (VAI) is a mathematical model associated with cardiometabolic risk in adults, but studies on children failed to support this association. Our group has proposed a pediatric VAI model using pediatric ranges, but it has not yet been evaluated and needs further adjustments. The objective of this study was to further adjust the proposed pediatric VAI by age, creating a new pediatric metabolic index (PMI), and assess the correlation of the PMI with insulin resistance indexes and hepatic enzymes...

The aim of this study was to evaluate the relationship between naturally occurring Leishmania spp. infections in dogs (Canis familiaris) and the practical implications of the use of serological and molecular methods to confirm diagnoses. The study population consisted of 96 domestic dogs in southeastern Brazil. Serum samples were tested for the presence of anti-Leishmania immunoglobulin G (IgG) antibodies using four commercial canine visceral leishmaniasis kits. Dogs confirmed positive by immunofluorescence antibody test (IFAT) were culled and samples from mesenteric lymph nodes, spleen border, bone marrow and ear skin were taken and submitted to DNA extraction...

A rapid, sensitive and specific tool for detection of Leishmania infantum infection in Humans would be highly desirable, because it would allow control interventions in endemic areas of visceral leishmaniasis. This study was carried out at the Reference National Laboratory of Leishmaniasis (RNLL) in National Institute of Hygiene (NIH) Morocco, in order to evaluate the diagnostic potential of immunochromatographic dipstick test (ICT) rk39 in Moroccan suspected VL patients. A total of 49 admitted patients with strong clinical suspicion of VL and 40 healthy controls were investigated for the performance of the ICT rk39...

OBJECTIVE: To test in an animal model the hypothesis that rhPRG4 (lubricin), a highly O-glycosylated mucin-like glycoprotein, may be a novel surface-active therapeutic for treating bladder permeability with co-morbid bowel permeability. Previously we showed that inducing bladder permeability in rats with dilute protamine sulfate (PS) produced colonic permeability and visceral hypersensitivity, suggesting increased bladder permeability could represent an etiologic factor in both Interstitial Cystitis/Bladder Pain Syndrome (IC/BPS) and Irritable Bowel Syndrome (IBS)...

OBJECTIVES: Visceral arteries in fenestrated and branched endovascular repair (F/BEVAR) have been addressed by fenestrations or directional side branches. Inner branches, as used in the arch branched device, could provide an extra option for visceral arteries "unsuitable" for fenestrations or directional side branches. Early experience with the use of inner branches for visceral arteries in F/BEVAR is described. METHODS: All consecutive patients treated by F/BEVAR for complex abdominal aortic aneurysm (AAA) or thoraco-abdominal aneurysm (TAAA) using stent grafts with inner branches were included...

Beyond their well-known role in embryonic development of the central and peripheral nervous system, neurotrophins, particularly nerve growth factor and brain-derived neurotrophic factor, exert an essential role in pain production and sensitization. This has mainly been studied within the framework of somatic pain, and even antibodies (tanezumab and fasinumab) have recently been developed for their use in chronic somatic painful conditions, such as osteoarthritis or low back pain. However, data suggest that neurotrophins also exert an important role in the occurrence of visceral pain and visceral sensitization...

Abdominal distention occurred at an incidence of 1% (15 from 1500 fish) in the population of 1-year-old bester (Huso huso × Acipenser ruthenus). Computed tomography (CT) images and radiographs showed a soft tissue mass compressed the posterior part of the swim bladder. Ultrasonography showed that the masses had different patterns. Internal examination revealed the abdominal cavities to be filled with large masses which appeared to encompass most of the visceral organs, including the swim bladder. The masses originated from the posterior kidney...

Melatonin regulates circadian rhythms but also has antioxidative and anti-inflammatory effects that ameliorate metabolic disorders. We investigated the effects of the selective melatonin agonist ramelteon on cardiac and adipose tissue pathology in the DahlS.Z-Leprfa /Leprfa (DS/obese) rat, a model of metabolic syndrome (MetS). Rats were treated with a low (0.3 mg/kg per day) or high (8 mg/kg per day) dose of ramelteon from 9 to 13 weeks of age. Ramelteon treatment at either dose attenuated body weight gain, left ventricular fibrosis, and diastolic dysfunction, as well as cardiac oxidative stress and inflammation, without affecting hypertension or insulin resistance...

Hashimoto's Thyroiditis (HT) is a common organ-specific autoimmune disorder associated with a high incidence, and insulin resistance is highly related to autoimmune. Here, we examined the insulin sensitivity in HT patients and found decreased insulin sensitivity occurred in HT patients. To explore the relationship between impaired insulin sensitivity and immune status, we established HT model mice which showed similar pathological features and immune features to HT patients. In HT model mice, reinfusion of regulatory T cells (Tregs) from peripheral blood of normal mice could improve insulin sensitivity and decrease the inflammation...

The visceral (VIS) and subcutaneous (SQ) fat pads are developmentally distinct white adipose tissue depots and contribute differently to inflammation and insulin resistance associated with obesity. The basic helix-loop-helix transcriptional regulator transcription factor 21 (TCF21) is a marker gene for white adipose tissues and is abundantly expressed in VIS-derived adipose stem cells (ASCs), but not in SQ-derived ASCs. However, TCF21's role in regulating fat depot-specific gene expression and function is incompletely understood...

BACKGROUND: Despite the improvements in the early detection and treatment of non-metastatic esophageal cancer, more than half of patients undergoing a curative treatment for esophageal cancer will develop recurrence within three years. The prognosis of these patients is poor. However, a wide range in overall survival has been reported, depending on the pattern of recurrence, and no optimal treatment strategy following recurrence has yet been uniformly accepted. AIM: In this article, we aimed to systematically review the literature for the role of surgical resection of metachronous distant metastasis following primary treatment of esophageal cancer...

Despite being widely used for several years, the endovascular aortic repair (EVAR) of a thoracoabdominal aneurysm (TAAA) remains challenging, particularly the revascularization of the abdominal aortic visceral branches. A 66-year-old male was admitted to hospital with abdominal bloating and pain. Computed tomographic angiography (CTA) confirmed a Crawford type III TAAA from the distal descending aorta to the suprarenal abdominal aorta that involved the celiac axis, accompanied with an occlusion of the left subclavian artery...

Background and Objectives: Bidirectional signaling between the gastrointestinal tract and the brain is vital for maintaining whole-body homeostasis. Moreover, emerging evidence implicates vagal afferent signaling in the modulation of host physiology by microbes, which are most abundant in the colon. This study aims to optimize and advance dissection and recording techniques to facilitate real-time recordings of afferent neural signals originating in the distal colon. New Protocol: This paper describes a dissection technique, which facilitates extracellular electrophysiological recordings from visceral pelvic, spinal and vagal afferent neurons in response to stimulation of the distal colon...
