Low-density Lipoprotein Subclasses are Associated with Serum Uric Acid Levels
Clinical Laboratory
|August 28, 2018
Summary
High uric acid (UA) levels correlate with small, dense low-density lipoprotein cholesterol (sdLDL-C) and malondialdehyde-modified low-density lipoprotein (MDA-LDL) in Japanese adults. This association suggests a link between UA, LDL subclasses, and metabolic health.
Area of Science:
- Cardiovascular Research
- Metabolic Syndrome Studies
- Lipid Metabolism
Background:
- Uric acid (UA) and low-density lipoprotein (LDL) subclasses are linked to coronary heart disease and metabolic syndrome (MetS).
- The specific relationship between UA and LDL subclasses remains unclear.
- Understanding this link is crucial for cardiovascular and metabolic health research.
Purpose of the Study:
- To investigate the association between serum uric acid (UA) levels and specific LDL subclasses.
- To explore the correlation between UA and small, dense LDL cholesterol (sdLDL-C) and malondialdehyde-modified LDL (MDA-LDL).
- To identify clinical factors associated with elevated UA and adverse lipid profiles.
Main Methods:
- Analysis of 633 Japanese subjects without relevant pre-existing conditions.
- Measurement of serum UA, sdLDL-C, and MDA-LDL levels during annual health examinations.
- Statistical analysis including correlation and multiple linear regression to determine associations.
Main Results:
- Serum UA positively correlated with both sdLDL-C and MDA-LDL.
- Male gender, waist circumference, HDL-C, triglycerides, and MDA-LDL were associated with higher UA.
- Higher UA tertiles corresponded with increased sdLDL-C and MDA-LDL, and a worse metabolic profile.
Conclusions:
- Both LDL particle size and oxidized LDL are significantly associated with serum UA levels.
- Findings highlight a potential link between UA, LDL subclasses, and metabolic dysfunction in Japanese individuals.

This lesson defines the leveling effect in acidic and basic solutions and its role in aqueous and non-aqueous solutions. It is essential to understand the competing nature of various species in a chemical system.
The Leveling Effect of a Solvent
A generic acid (HA) reacts with the generic base (B-) to yield the corresponding conjugate base (A-) and conjugate acid (HB):

00:56Density
19.9K
Density is an important characteristic of substances, crucial in determining whether an object sinks or floats in a fluid. Its SI unit is kg/m3, and its cgs unit is g/cm3. The density of an object helps in identifying its composition, and also reveals information about the phase of the matter and its substructure. The densities of liquids and solids are roughly comparable, consistent with the fact that their atoms are in close contact. However, gases have much lower densities than liquids and...

01:29Leveling Effect
1.4K
In acid-base chemistry, the leveling effect refers to the limitation imposed by the solvent on the strength of acids and bases in solution. When a base stronger than the solvent's conjugate base is used, it deprotonates the solvent until the base is entirely consumed, making it ineffective against weaker acids. Conversely, an acid stronger than the solvent's conjugate acid protonates the solvent until the acid is depleted, rendering it ineffective against weaker bases. Essentially, the...

Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

01:21Current Density
5.1K
The total amount of current flowing through one unit value of a cross-sectional area is referred to as current density. If the current flow is uniform, the amount of current flowing through a conductor is the same at all points along the conductor, even if the conductor area varies. The current density consists of the local magnitude and direction of the charge flow, which varies from point to point. Current density is measured in amperes per meter square, and direction is defined as the net...

Biological organization is the classification of biological structures, ranging from atoms at the bottom of the hierarchy to the Earth's biosphere. Each level of the hierarchy represents an increase in complexity that builds upon the previous level.
