Proliferative kidney disease (PKD) is a widespread disease caused by the endoparasite Tetracapsuloides bryosalmonae (Myxozoa: Malacosporea). Clinical disease, provoked by the proliferation of extrasporogonic parasite stages, is characterized by a chronic kidney pathology with underlying transcriptional changes indicative of altered B cell responses and dysregulated T-helper cell-like activities. Despite the relevance of PKD to European and North American salmonid aquaculture, no studies, to date, have focused on further characterizing the B cell response during the course of this disease...

OBJECTIVE: MicroRNAs (miRNAs) play a critical role in metabolic regulation. Recently, we identified novel miRNAs in the whole blood of South African women of mixed ethnic ancestry. The aim of this study was to investigate whether five of these novel miRNAs are expressed in serum and whether their expression is altered during metabolic dysregulation. METHODS: Expression levels of the five novel miRNAs (MYN08, MYNO22, MYN059, MYNO66 and MYNO95) were measured in the serum of women with Impaired Glucose Tolerance (IGT) and Normoglycemia (NGT) (n=24), and in the whole blood of vervet monkeys fed a high-fat or standard diet (n=16) using quantitative real-time PCR...

According to the somatic marker hypothesis, autonomic measures and arousal modulation can reveal a difference in subgroups of patients developing impaired decision-making because of addictions. Previously, Pathological Gambling (PG) and Parkinson's Disease (PD) have been associated with differential arousal levels during gambling behavior. However, no research considered the specific autonomic responses of Parkinson's Disease patients with pathological gambling and with a previous history of gambling. Thus, this study investigated Skin Conductance Responses (SCRs), Skin Conductance Level (SCL) and Heart Rate (HR) during the Iowa Gambling Task (IGT) in two groups of PD patients with gambling disorder, active (PD Gamblers; n=14) or remitted (PD Non-Gamblers; n=13) and a control group of patients with Parkinson's Disease only (n=13)...

BACKGROUND: Patients with pancreatic insufficient cystic fibrosis (PI-CF) meeting standard criteria for normal glucose tolerance display impaired β-cell secretory capacity and early-phase insulin secretion defects. We sought evidence of impaired β-cell secretory capacity, a measure of functional β-cell mass, amongst those with early glucose intolerance (EGI), defined as 1-hour OGTT glucose ≥155mg/dL (8.6 mmol/L). METHODS: A cross-sectional study was conducted in the Penn and CHOP Clinical & Translational Research Centers...

AIMS: To describe the roles of intra-abdominal fat and its change in the remission of impaired glucose tolerance (IGT) to normal glucose tolerance (NGT). METHODS: We followed 157 Japanese Americans with IGT at baseline for 10-11 years without external intervention. We measured intra-abdominal and abdominal subcutaneous fat area (IAFA and ASFA) by computed tomography at baseline and at 5-6 years of follow-up. Change in IAFA and ASFA (ΔIAFA and ΔASFA) were calculated by subtracting baseline fat area from 5-6 year follow-up fat area...

We evaluated data from 10,088 participants without cardiovascular disease (CVD) who underwent 75 g oral glucose tolerance tests and had more than four visits during the first 5 years following the test to investigate the association between impaired glucose metabolism and visit-to-visit blood pressure (BP) variability. Participants were classified into groups of normal glucose tolerance (NGT), impaired fasting glucose (IFG), impaired glucose tolerance (IGT), and diabetes. Visit-to-visit BP variability was estimated for each individual using standard deviation (SD) and coefficients of variation (CV, defined as SD/mean)...

Current theories view impulsivity as an important factor in the explanation of sexual offending. While impulsivity itself is a multidimensional construct, response inhibition and impulsive decision-making are frequently discussed subcomponents. Impulsivity in sexual offenders could be triggered by sexual cues with high emotional significance. The present study compared response inhibition abilities and the degree of impulsive decision-making between 63 child sexual abusers and 63 nonoffending controls. A Go/No-Go task was used to assess response inhibition, while the Iowa Gambling Task (IGT) and the Game of Dice Task (GDT) were used for the assessment of decision-making...

BACKGROUND: Diabetes mellitus is usually preceded by a pre-diabetic stage before the clinical presentation of the disease, the influence of which on persons' quality of life is not adequately elucidated. The purpose of this study was to compare the Health-Related Quality of Life (HRQOL) of persons with pre-diabetes with that of diabetes or normal glucose tolerance (NGT), using the validated HRQOL-15D questionnaire. METHODS: The HRQOL-15D scores of 172 people with pre-diabetes (108 with Impaired Fasting Glucose [IFG], 64 with Impaired Glucose Tolerance [IGT], aged 58...

Anabolic-androgenic steroid (AAS) abuse is implicated in maladaptive decision making such as increased risk taking and problem gambling. Endogenous testosterone correlates with economic risk taking in both the stock market (Coates & Herbert, 2008) and in the laboratory, as measured by the Iowa Gambling Task (Stanton, Liening, & Schultheiss, 2011). Additionally, AAS use has been associated with problem gambling behavior in adolescents (Proimos, DuRant, Pierce, & Goodman, 1998). Thus, AAS may impair economic decision making...

BACKGROUND: There is limited literature about the perioperative factors which can predict endocrine insufficiency after pancreaticoduodenectomy (PD). The primary aim was to correlate percentage pancreatic remnant volume (%RV) after PD in nondiabetic patients with the development of new-onset impaired glucose tolerance/diabetes mellitus (IGT/DM). The secondary aim was to identify the risk factors for new-onset IGT/DM. METHODS: In this prospective study, all consecutive patients with resectable periampullary carcinoma and without IGT/DM were evaluated with fasting and postprandial plasma glucose, HbA1c, insulin, and C-peptide levels preoperatively and at 3 mo postoperatively...

Prunus persica (peach) trees carrying the "Pillar" or "Broomy" trait ( br ) have vertically oriented branches caused by loss-of-function mutations in a gene called TILLER ANGLE CONTROL 1 ( TAC1 ). TAC1 encodes a protein in the IGT gene family that includes LAZY1 and DEEPER ROOTING 1 ( DRO1 ), which regulate lateral branch and root orientations, respectively. Here we found that some of the native TAC1 alleles in the hexaploid plum species Prunus domestica , which has a naturally more upright stature, contained a variable length trinucleotide repeat within the same exon 3 region previously found to be disrupted in pillar peach trees...

Objective: To investigate the correlation of intermittent androgen-deprivation therapy (IADT) and continuous androgen-deprivation therapy (CADT) for advanced prostate cancer (PCa) with the risks of secondary diabetes mellitus (DM) and impaired glucose tolerance (IGT). METHODS: We conducted a retrospective case-control study of the advanced PCa patients treated by IADT or CADT in our hospital from January 2013 to December 2015. Based on the levels fasting blood glucose and 2-hour postprandial blood glucose, results of oral glucose tolerance test, and clinical symptoms of the patients, we statistically analyzed the IADT- or CADT-related risk factors for DM and IGT and the relationship of the body mass index (BMI), hypertension, smoking, and alcohol consumption with secondary DM and IGT...

Fat accumulation with aging is a serious problem; glucose-dependent insulinotropic polypeptide (GIP) is an incretin that plays an important role in fat accumulation. GIP receptor-knockout mice show reduced fat mass and improved insulin sensitivity associated with aging. Therefore, GIP is involved in fat accumulation and insulin resistance with aging. However, age-related changes of GIP secretion remain unclear. The present study aimed to elucidate age-related changes of GIP secretion and enteroendocrine K cells using GIP reporter (GIP-GFP knock-in heterozygous; GIPgfp/+ ) mice...

Objective: A subgroup of patients with Parkinson disease (PD) develops impulse control disorders (ICD) associated with their dopamine replacement therapy. Patients and their families may be reluctant to report ICD symptoms or unaware these symptoms are related to PD medication, which can make detecting an ICD difficult for clinicians. Ideally, a behavioral measure that is sensitive to ICD could be employed to ensure that patients with these behaviors are identified and treated. The Iowa Gambling Task (IGT), a standardized decision-making task, has proven sensitive in other populations with impulse control problems...
