This study aimed to investigate the expression and function of BKCa channels in the Sphincter of Oddi (SO) in a rabbit model of hypercholesterolemia (HC). New Zealand white rabbits were randomly divided into two groups: the control group was fed standard chow (n = 18) whereas the high-cholesterol group was fed cholesterol-enriched chow containing 1.5% cholesterol (n = 18). The serum cholesterol level was significantly greater in the HC groups than in the control group, but there was no significant difference in body weight between the control and HC groups...

Sphincter of Oddi dysfunction is caused by stenosis or dyskinesia of the sphincter of Oddi, leading to blockage of bile drainage from the common bile duct. We present the case of a 16-year-old female with chronic abdominal pain who underwent laparoscopic cholecystectomy for cholelithiasis but continued to experience abdominal pain, nausea, and vomiting along with persistently elevated ALT and AST levels. Postoperative abdominal ultrasound was nondiagnostic. Esophagogastroduodenoscopy showed mild reflux esophagitis and mild chronic Helicobacter pylori-negative gastritis...

BACKGROUND AND AIMS: Biopsy of the ampulla of Vater may be performed to evaluate for ampullary adenomas, suspected ampullary tumors and immunohistological staining for autoimmune pancreatitis. Ampullary biopsies are commonly performed at the time of endoscopic retrograde cholangiopancreatography (ERCP). Due to the well-established complication rate following ERCP, the contribution of ampullary biopsy as a potential independent risk factor would require a controlled comparison. METHODS: A matched-pairs, case-control analysis was performed for patients undergoing ERCP with or without ampullary biopsy...

Liver function assessment by hepatocyte-specific contrast-enhanced magnetic resonance imaging is becoming a new biomarker. Liver function can be assessed by T1 mapping (reduction rate) and signal intensity measurement (relative enhancement ratio) before and after GD-EOB-DTPA (gadoxetic acid) administration, as alternative to Tc-99m galactosyl serum albumin scintigraphy, 99m Tc-labeled mebrofenin scintigraphy, and indocyanine green clearance test. Magnetic resonance imaging assessment of liver function can enable diagnosis of cirrhosis, nonalcoholic fatty liver disease associated fibrosis and steatohepatitis, primary sclerosing cholangitis, toxic hepatitis, and chemotherapy and radiotherapy-related changes, which may be only visible on hepatobiliary phase images...

Ruminants obtain nutrients from microbial fermentation of plant material, primarily in their rumen, a multilayered forestomach. How the different layers of the rumen wall respond to diet and influence microbial fermentation, and how these process are regulated, is not well understood. Gene expression correlation networks were constructed from full thickness rumen wall transcriptomes of 24 sheep fed two different amounts and qualities of a forage and measured for methane production. The network contained two major negatively correlated gene sub-networks predominantly representing the epithelial and muscle layers of the rumen wall...

Estimates of genetic/phenotypic covariances and economic values for slaughter weight, growth, feed intake and efficiency, and three potential methane traits were compiled to explore the effect of incorporating methane measurements in breeding objectives for cattle and meat sheep. The cost of methane emissions was assumed to be zero (scenario A), A$476/t (based on A$14/t CO equivalent and methane's 100-yr global warming potential [GWP] of 34; scenario B), or A$2,580/t (A$30/t CO equivalent combined with methane's 20-yr GWP of 86; scenario C)...

Feed intake (FI), live weight (LW), and ADG were recorded over 31 d in ninety-six 12-month-old ewes (progeny of 4 sires) given ad libitum access to chaffed lucerne/cereal hay. Methane (CH) and CO emissions of each ewe were measured for 40 to 60 min in portable accumulation chambers (PAC) and in respiration chambers (RC) over 22 h. Testing in RC increased the variability of FI on the test day and depressed the amount eaten from an average of 1,384 to 1,062 g/d; FI depression increased by 0.63 ± 0.24 percentage points for every kilogram of additional LW...

Acute pancreatitis (AP) is a potentially serious disease whose incidence is on the increase. Pancreas divisum does not meet the required criteria to be considered an aetiological factor. Sphincter of Oddi dysfunction may be another cause of idiopathic AP. Less invasive methods cannot replace Sphincter of Oddi manometry in diagnosis. Almost half of patients with systemic inflammatory response syndrome develop organ failure, but the mechanisms involved are not completely understood. Obesity is a risk factor for severity in AP; the cause could be the presence of free unsaturated fatty acids, which have pro-inflammatory activity...

Glucagon is well acknowledged as a sphincter of Oddi relaxant for both diagnostic and therapeutic uses in choledocholithiasis, and an empiric treatment for β-blocker overdose. Although it has been implicated in inducing cardiovascular crises in patients with asymptomatic pheochromocytoma, adverse effects in other patient populations have not been characterized. This case report describes a patient with hypertension controlled on β blockers who, after glucagon administration during an intraoperative cholangiography, experienced hypertensive emergency despite adequate pain control...

OBJECTIVE: The aim was to assess the efficacy of rituximab for the cutaneous manifestations of adult DM and JDM. METHODS: Patients with refractory adult DM (n = 72) and JDM (n = 48) were treated with rituximab in a randomized placebo-phase-controlled trial [either rituximab early drug (week 0/1) or rituximab late arms (week 8/9), such that all subjects received study drug]. Stable concomitant therapy was allowed. Cutaneous disease activity was assessed using the Myositis Disease Activity Assessment Tool, which grades cutaneous disease activity on a visual analog scale...

Investigating protective and risk factors that influence mental health in young people is a high priority. While previous cross-sectional studies have reported associations between diet and mental health among adolescents, few prospective studies exist. The aim of this study was to examine prospective relationships between dietary patterns and mental health among adolescents participating in the Western Australian Pregnancy Cohort (Raine) Study. Self-report questionnaires were used to assess indicators of mental health (Youth Self-Report externalizing/internalizing T-scores) and Western and Healthy dietary patterns (identified using factor analysis) at 14 (2003-2005) and 17 years (2006-2008)...

BACKGROUND: While there is a large body of work supporting the importance of early feeding practices on cognitive, immunity, behavioural and mental outcomes, few longitudinal studies have focused on motor development. The relationship between duration of breast feeding and motor development outcomes at 10, 14, and 17years were examined. METHODS: Data were obtained from the Western Australian Pregnancy (Raine) Study. There were 2868 live births recorded and children were examined for motor proficiency at 10 (M=10...

: In a continuation of a prospective longitudinal cohort study in a healthy population on the course of skull shape from birth to 24 months, at 5 years of age, 248 children participated in a follow-up assessment using plagiocephalometry (ODDI-oblique diameter difference index, CPI-cranio proportional index). Data from the original study sampled at birth, 7 weeks, 6, 12, and 24 months were used in two linear mixed models. MAIN FINDINGS: (1) if deformational plagiocephaly (ODDI <104%) and/or positional preference at 7 weeks of age are absent, normal skull shape can be predicted at 5 years of age; (2) if positional preference occurs, ODDI is the highest at 7 weeks and decreases to a stable lowest value at 2 and 5 years of age; and (3) regarding brachycephaly, all children showed the highest CPI at 6 months of age with a gradual decrease over time...

Dysfunction of the sphincter of Oddi is a rare disease that causes about 20% of recurrent idiopathic pancreatitis. In order to suspect its existence, it is mandatory to have ruled out all other causes of acute pancreatitis. Then, the disease needs to be classified by degree of dysfunction and have a manometry performed as it is considered the gold standard of diagnosis. Manometry is used to guide treatment and its method of choice is usually an endoscopic sphincterotomy. In this article a case of recurrent pancreatitis is discussed, which after a thorough study that ruled out other etiologies, was diagnosed as a pancreatic-type dysfunction of the sphincter of Oddi...
