Abstract:

Statins are widely used to treat hypercholesterolemia. Statins inhibit cholesterol biosynthesis, thereby activating genes involved in cholesterol homeostasis, which are under the control of the Sterol Regulatory Element (SRE). Statins also have cholesterol-independent beneficial cardiovascular effects mediated through the phosphoinositide 3-kinase (PI3-K) / Akt signaling pathway and by inhibition of protein prenylation. Because statins inhibit the synthesis of isoprenoids, they can act by inhibiting the small signaling GTPases Ras and Rho, which require post-translational prenylation to become

Abstract:

The cholesterol-lowering effect of corn fiber oil, obtained from the seed coats of corn kernels, has been reported previously. Corn fiber oil contains phytosteryl fatty acyl esters, ferulate phytostanyl esters, and free phytosterols. To date, however, no studies have examined the cholesterol-lowering efficacy of ferulate phytostanyl esters. Moreover, although plant stanols and sterols have been established as cholesterol-lowering agents over the past five decades, their exact mechanisms of action are not clearly understood. One of the possible mechanism is that plant sterols/stanols disrupts t

Abstract:

The objective of this study was to examine the effects of plant sterols and/or glucomannan on lipid profiles and cholesterol kinetics in hyperlipidemic individuals with or without type 2 diabetes. It was hypothesized that plant sterols and glucomannan reduce circulating cholesterol levels and may have an additive or synergistic effect when combined by reducing cholesterol absorption. Thirteen type 2 diabetics and sixteen non-diabetics all mildly hypercholesterolemic free living subjects participated in a randomized crossover trial consisting of 4 phases, 21 days each. Subjects consumed

Abstract:

The objective of this research was to examine the effects of sitosterol and sitostanol supplementation on plasma cholesterol levels and cholesterol metabolism in hypercholesterolemic subjects consuming a fixed foods diet in a four-phase crossover design. It was hypothesized that addition of either phytosterols, phytostenols, or a 50:50 mixture of sterols and stanols to butter would reduce circulating cholesterol levels, despite butter's hypercholesterolemic effect, through actions involving cholesterol absorption, synthesis, and turnover rates. The data obtained indicate that in their free, un

Abstract:

Background. A high ratio of total cholesterol to high-density lipoprotein (HDL) cholesterol, in addition to increased levels of small low-density lipoprotein (LDL) particles, are important indicators of cardiovascular disease risk. Therefore, interventions that combine the lowering of total cholesterol and raising of HDL cholesterol concentrations that also increase LDL particle size, may be preventive against cardiovascular disease. Plant sterols decrease total cholesterol and LDL cholesterol levels by 10-15%, while exercise increases HDL cholesterol levels by 4-22%. In view of their compleme

Abstract:

The purpose of the present study was to determine the acute effects of strenuous exercise on the following blood constituents: total cholesterol (TC) 1 triglycerides (TG) 1 high density lipoproteins (HDL-C) 1 and low density lipoproteins (LDL-C). A single case study was performed during a 20 day testing period. Two century bicycle rides ( 100 miles) were used as the strenuous exercise bouts. Blood samples were drawn each day and immediately after each 100 mile ride. A pre-set exercise and diet regimen were followed every day of the 20 day procedure.

The purpose of this study was to determine the effectiveness of group nutrition and physical activity education classes in lowering cholesterol levels of worksite employees at 6-and 12-month intervals. A total of 32 participants were followed through the study. The group of participants included 24 female and 8 males, all over the age of 40. The data were analyzed using one-way ANOV A with repeated n1easures, post¬hoc analysis, Pearson's correlation coefficient, and ANCOV A to test six null hypotheses.

Discerning the cellular and molecular mechanisms responsible and amendable to therapy represents a growing challenge in medicine. At a cellular level, increased activity of the hexosamine biosynthesis pathway (HBP), a sensor of excess energy status, has been suggested to promote the exacerbation of insulin resistance through increasing adipose tissue and skeletal muscle membrane cholesterol content.

Indiana University-Purdue University Indianapolis (IUPUI)<br>A recent review of randomized controlled trials found that trivalent chromium (Cr3+) supplementation significantly improved glycemia among patients with diabetes, consistent with a long-standing appreciation that this micronutrient optimizes carbohydrate metabolism. Nevertheless, a clear limitation in the current evidence is a lack of understanding of Cr3+ action. We tested if increased AMP-activated protein kinase (AMPK) activity, previously observed in Cr3+-treated cells or tissues from Cr3+-supplemented animals, mediates improved
