Bergamot Polyphenols Improve Dyslipidemia and Pathophysiological Features in a Mouse Model of Non-Alcoholic Fatty Liver Disease.

There is a need for continued drug development for nonalcoholic steatohepatitis (NASH). Bergamot is a plant whose fruit juice is enriched with flavonoids and phenolic compounds which improves dyslipidemia and markers of systemic inflammation in patients with Metabolic Syndrome. The aim of this study was to perform a preclinical "proof of concept" study of Bergamot polyphenolic formulation (BPF99) for the treatment of NASH.

Effect of Calf Gender on Milk Yield and Fatty Acid Content in Holstein Dairy Cows.

The scale of sexed semen use to avoid the birth of unwanted bull calves in the UK dairy industry depends on several economic factors. It has been suggested in other studies that calf gender may affect milk yield in Holsteins- something that would affect the economics of sexed semen use. The present study used a large milk recording data set to evaluate the effect of calf gender (both calf born and calf in utero) on both milk yield and saturated fat content.

Bergamot polyphenol fraction prevents nonalcoholic fatty liver disease via stimulation of lipophagy in cafeteria diet-induced rat model of metabolic syndrome.

Nonalcoholic fatty liver disease (NAFLD) is the most common liver disease in industrialized countries. Defective autophagy of lipid droplets (LDs) in hepatocytes, also known as lipophagy, has recently been identified as a possible pathophysiological mechanism of NAFLD. Experimental and epidemiological evidence suggests that dietary polyphenols may prevent NAFLD.

Quantifying inter-group variability in lactation curve shape and magnitude with the MilkBot(®) lactation model.

Genetic selection programs have driven development of most lactation models, to estimate the magnitude of animals' productive capacity from sampled milk production data. There has been less attention to management and research applications, where it may also be important to quantify the shape of lactation curves, and predict future daily milk production for incomplete lactations since residuals between predicted and actual daily production can be used to quantify the response to an intervention. A model may decrease the confounding effects of lactation stage, parity, breed, and possibly other factors depending on how the model is constructed and used, thus increasing the power of statistical analyses.

Effect of antioxidants on X-ray-induced γ-H2AX foci in human blood lymphocytes: preliminary observations.

Purpose: To investigate the effect of a radioprotective oral agent containing a formulation of antioxidants and glutathione-elevating compounds on the extent of x-ray-induced γ-H2AX foci formation.

Materials And Methods: The study was approved by local ethics committee and informed consent was obtained from each subject. In vitro experiments with blood lymphocytes of 25 healthy volunteers were performed without antioxidants and with antioxidants added either before or immediately after irradiation (10 mGy).

Lipoprotein-associated phospholipase A₂ activity predicts progression of subclinical coronary atherosclerosis.

Background: Lipoprotein-associated phospholipase A₂ (Lp-PLA₂) is a lipoprotein-associated enzyme that cleaves oxidized phosphatidylcholines, generating pro-atherosclerotic lysophosphatidylcholine and oxidized free fatty acids. Lp-PLA₂ is independently associated with cardiovascular disease (CVD) in a variety of populations. Coronary calcium is a measure of subclinical CVD, and progression of coronary calcification predicts future CVD events.

Reduced heart rate variability predicts progression of coronary artery calcification in adults with type 1 diabetes and controls without diabetes.

Aim: Reduced heart rate variability (HRV) is a manifestation of cardiac autonomic neuropathy, a known complication of type 1 diabetes (T1D). We evaluated whether HRV predicted coronary artery calcium (CAC) progression.

Methods: Subjects between 19 and 56 years of age with T1D or those without diabetes from the Coronary Artery Calcification in Type 1 Diabetes study underwent supine deep breathing 12-lead electrocardiograms.

Reproductive history and hormonal birth control use are associated with coronary calcium progression in women with type 1 diabetes mellitus.

Context: Coronary artery disease is increased in women with type 1 diabetes (T1D), compared with nondiabetic (Non-DM) women. Women with T1D have more menstrual dysfunction and are less likely to use hormonal birth control (BC) than Non-DM women.

Objective: The purpose of this study was to determine whether coronary artery calcium (CAC) is associated with menstrual dysfunction and BC use in women with T1D.

Coronary artery calcium scanning: Clinical paradigms for cardiac risk assessment and treatment.

Background: Coronary artery calcium (CAC) scanning is being increasingly used for cardiac risk assessment in asymptomatic patients, particularly in those with a Framingham 10-year risk of 10% to 20%. Physician awareness of this technology and its appropriate uses and limitations is crucial to appropriate use.

Methods: With the goal of establishing clinical paradigms, this document integrates the results of key published articles, Framingham Risk Score, National Cholesterol Education Program Adult Treatment Plan III guidelines, American College of Cardiology/American Heart Association exercise testing and angiographic guidelines, and the authors' extensive clinical experience.

A randomized trial of pegylated interferon alpha-2b plus ribavirin in the retreatment of chronic hepatitis C.

Objectives: The efficacy of combination therapy with pegylated interferon (PEG IFN) alpha plus ribavirin (RBV) in the retreatment of chronic hepatitis C (CHC) in patients who previously failed combination standard IFN plus RBV or IFN monotherapy has not been well established.

Methods: Three hundred and twenty-one CHC patients including virologic nonresponders to combination IFN plus RBV (n = 219) or IFN monotherapy (n = 47), and relapsers to combination therapy (n = 55) were randomized to receive PEG IFN alpha-2b 1.5 microg/kg per wk plus RBV 800 mg per day (Regimen A, n = 160) or PEG IFN alpha-2b 1.

Effects of sevelamer and calcium on coronary artery calcification in patients new to hemodialysis.

Background: Hemodialysis patients are at increased risk for progressive coronary artery calcification; however, the development and progression of this disease process in patients new to hemodialysis is unknown.

Method: One hundred and twenty-nine patients new to hemodialysis were randomized to receive calcium containing phosphate binders or the noncalcium phosphate binder sevelamer hydrochloride. Subjects underwent electron beam computed tomography scanning (EBCT) at entry into the study and again at 6, 12, and 18 months.

Low plasma adiponectin levels predict progression of coronary artery calcification.

Background: Circulating adiponectin levels are lower in men than in women and lower in advanced coronary artery disease, obesity, and type 2 but not type 1 diabetes. However, it is not known whether low adiponectin levels predict development of atherosclerosis independently of other cardiovascular risk factors.

Methods And Results: Progression of coronary artery calcification (CAC) over an average of 2.

Hypertension prevalence, awareness, treatment, and control in an adult type 1 diabetes population and a comparable general population.

Objective: To compare the prevalence, awareness, treatment, and control of hypertension in a population-representative sample of adults with type 1 diabetes and comparable nondiabetic control subjects.

Research Design And Methods: In 2000-2002, the Coronary Artery Calcification in Type 1 Diabetes Study enrolled 1,416 individuals aged 19-56 years with no known history of coronary artery disease: 652 type 1 diabetic patients (46% male, mean age 37 years) and 764 nondiabetic control subjects (50% male, mean age 39 years). Subjects were asked if they had been told by a physician that they had hypertension or were on a blood pressure medication.

Coronary and aortic calcifications in patients new to dialysis.

Background: Vascular calcification has been associated with all cause and cardiovascular mortality in patients with end-stage kidney disease (ESRD). Whether vascular calcification is present in persons with advanced chronic kidney disease starting dialysis or develops in patients on dialysis is unknown. The purpose of this study was to examine the prevalence of vascular and coronary calcification in patients new to hemodialysis.

Evaluating changes in coronary artery calcium: an analytic method that accounts for interscan variability.

Objective: Coronary calcium measured by electron beam CT is associated with coronary disease and can be used to predict coronary disease events. Studies investigating changes in coronary calcium need to address interscan variability as it relates to the overall coronary calcium score in defining progression or regression of coronary calcium over time. SUBJECTS AND METHODS.

Effect of type 1 diabetes on the gender difference in coronary artery calcification: a role for insulin resistance? The Coronary Artery Calcification in Type 1 Diabetes (CACTI) Study.

The objective of this is study was to examine whether estimated insulin resistance and insulin resistance-related factors are associated with coronary artery calcification (CAC) in 1,420 asymptomatic participants in the Coronary Artery Calcification in Type 1 Diabetes (CACTI) study. A total of 656 patients with type 1 diabetes and 764 control subjects aged 20-55 years were examined. CAC was assessed by electron-beam computed tomography.

Progression of coronary artery calcification in type 1 diabetes: the importance of glycemic control.

Objective: Coronary artery disease (CAD) occurs earlier in life and is more often fatal in people with type 1 diabetes. This excess risk seems to be higher than in those with type 2 diabetes and is poorly explained by conventional risk factors. The role of glycemic control is controversial and has not been previously addressed in a prospective manner using a reliable marker for subclinical CAD, such as coronary artery calcification (CAC), measured by electron beam computed tomography (EBCT).

A common promoter polymorphism in the hepatic lipase gene (LIPC-480C>T) is associated with an increase in coronary calcification in type 1 diabetes.

Type 1 diabetes is associated with coronary heart disease (CHD) and coronary artery calcification (CAC), a measure of subclinical CHD. The hepatic lipase gene promoter polymorphism (LIPC-480C>T) is a common variant affecting lipid metabolism. This study examined the relation between the LIPC-480C>T and CAC in type 1 diabetes.
