Insights

Higher resistin levels in blood and carotid plaques are linked to unstable plaques and ischemic stroke events. Resistin may serve as a biomarker for stroke risk in patients with carotid artery stenosis.

Area of Science:

  • Cardiovascular Medicine
  • Neurology
  • Biomarker Research

Background:

  • Ischemic stroke risk correlates with carotid stenosis severity and plaque vulnerability.
  • Identifying biomarkers for plaque instability and stroke is crucial for patient management.

Purpose of the Study:

  • To investigate the association between circulating and plaque resistin levels with carotid plaque vulnerability and ischemic stroke events.
  • To explore resistin's role as a potential biomarker in patients with moderate- to high-grade carotid artery stenosis.

Main Methods:

  • Recruited 40 ischemic stroke patients and 38 asymptomatic patients undergoing carotid endarterectomy.
  • Measured serum resistin via ELISA and plaque resistin expression via immunohistochemistry.
  • Histologically classified carotid endarterectomy specimens.

Main Results:

  • Significantly higher serum and plaque resistin levels were observed in patients with unstable carotid plaques and ischemic stroke events.
  • Higher serum resistin levels were independently associated with plaque instability and ischemic stroke.
  • Resistin levels correlated with specific histological features of plaque instability.

Conclusions:

  • Serum resistin levels may serve as a potential biomarker for plaque vulnerability and ischemic stroke in patients with carotid artery stenosis.
  • Plaque resistin expression is associated with histological indicators of plaque vulnerability.

Anatomy of the Circulatory System02:03

Anatomy of the Circulatory System

The human circulatory system consists of blood, blood vessels that carry blood away from the heart, around the body, and back to the heart, and the heart itself, which acts as a central pump. The systemic circuit supplies blood to the whole body, the coronary circuit supplies blood to the heart, and the pulmonary circuit supplies blood flow between the heart and lungs.

Microtubule Instability02:17

Microtubule Instability

Microtubules are hollow cylindrical filaments having a diameter of approximately 25 nm and a length that varies from 200 nm to 25 μm. GTP-bound tubulin subunits form αβ-heterodimers for microtubule assembly. These core building blocks interact longitudinally, polymerizing into protofilaments. The protofilaments then interact with one another through lateral bonding forces to form stable cylindrical microtubules. These cylindrical filaments are dynamic as they undergo repeated...

Association Areas of the Cortex01:21

Association Areas of the Cortex

Association areas are regions of the cerebral cortex that do not have a specific sensory or motor function. Instead, they integrate and interpret information from various sources to enable higher cognitive processes such as memory, learning, and decision-making. Some key association areas include the following:
Prefrontal Association Area: This area is located in the frontal lobe and is involved in planning, decision-making, and moderating social behavior. It connects with primary motor areas,...

Associative Learning01:27

Associative Learning

Associative learning is a fundamental concept in behavioral psychology, wherein a connection is established between two stimuli or events, leading to a learned response. This process is critical in understanding how behaviors are acquired and modified. Conditioning, the mechanism through which associations are formed, can be divided into two main types: classical conditioning and operant conditioning, each elucidating different aspects of associative learning.
Classical conditioning, also known...

Integration of Synaptic Events01:28

Integration of Synaptic Events

Synaptic integration mainly includes the summation of graded potentials. Graded potentials, regardless of their type, cause subtle alterations in membrane voltage, resulting in either depolarization or hyperpolarization. These incremental changes, when combined or summed, can propel the neuron toward its threshold. Consider, for example, a membrane experiencing a +15 mV shift, causing it to depolarize from -70 mV to -55 mV. In this scenario, graded potentials govern the membrane's ability to...

Leveling Effect01:29

Leveling Effect

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...
