概括

大型抑郁症 (MDD) 与大脑血流 (CBF) 的减少有关,但没有改变血脑屏障 (BBB) 的水交换. 像LPS和IL-10这样的外周炎症标志物,以及较低的CBF,可以预测MDD.

科学领域:

神经成像是一种神经成像.
精神病学是一个精神病学.
生物标志物生物标志物

背景情况:

扩散准备的伪连续动脉旋转标签 (DP-pCASL) 量化脑血流 (CBF) 和血脑屏障 (BBB) 水交换速率 (kw).
在主要抑郁障碍 (MDD) 中,BBB水交换的作用仍然在很大程度上未被描述.

研究的目的:

研究BBB水交换 (kW),CBF,外周炎症和MDD之间的关系.
为了识别与MDD相关的成像和炎症标志物.

主要方法:

DP-pCASL用于测量85名MDD患者和51名对照者的全球和区域 kw和CBF.
血中脂聚糖 (LPS) 和炎症性细胞因子 (IL-6,IL-10,TNF-α,IFN-γ) 的水平被量化.
进行了后勤回归分析,以确定MDD的预测因素.

主要成果:

与对照组相比,MDD患者的全球CBF显著降低 (p = 0.006),特定的前额头和带带肌区域的减少.
在MDD患者和对照组之间没有观察到全球或区域 kw 的显著差异 (p = 0.958).
较低的CBF,升高的LPS和IL-10水平被确定为MDD的独立预测因素,在将患者与对照区分开来时达到83.1%的准确性.

结论:

DP-pCASL证实了MDD中减少的CBF,支持其在疾病病理生理学中的作用.
在MDD中,BBB的水交换 (kW) 似乎没有显著改变.
CBF,LPS和IL-10是MDD的显著预测因素,突出了神经血管功能和炎症之间的相互作用.

Blood Flow

Blood Flow

Blood is pumped by the heart into the aorta, the largest artery in the body, and then into increasingly smaller arteries, arterioles, and capillaries. The velocity of blood flow decreases with increased cross-sectional blood vessel area. As blood returns to the heart through venules and veins, its velocity increases. The movement of blood is encouraged by smooth muscle in the vessel walls, the movement of skeletal muscle surrounding the vessels, and one-way valves that prevent backflow.

Physiological Pharmacokinetic Models: Blood Flow-Limited Versus Diffusion-Limited Models

Physiological Pharmacokinetic Models: Blood Flow-Limited Versus Diffusion-Limited Models

Physiological pharmacokinetic models, often called flow-limited or perfusion models, typically assume a swift drug distribution between tissue and venous blood, creating a rapid drug equilibrium. This premise is based on the idea that drug diffusion is extremely fast, and the cell membrane presents no barrier to drug permeation. In this scenario, where no drug binding occurs, the drug concentration in the tissue equals that of the venous blood leaving the tissue. This greatly simplifies the...

Autoregulation of Blood Flow

Autoregulation of Blood Flow

Autoregulation mechanisms are characterized by their inherent capacity for self-regulation without necessitating specific nervous stimulation or endocrine control. These mechanisms facilitate the adjustment of blood flow and, therefore, perfusion specific to each tissue region. This self-regulation encompasses chemical signals and myogenic controls.
Chemical Signaling in Autoregulation
Chemical signaling operates at the precapillary sphincter level, inciting either contraction or relaxation....

Applications of Integration to Find Blood Flow

Applications of Integration to Find Blood Flow

Blood flow through a cylindrical blood vessel can be mathematically described using the principles of laminar flow, a regime in which fluid moves smoothly in parallel layers. In this model, the velocity of the blood is not uniform across the cross-section of the vessel; rather, it varies with the radial distance from the center. The maximum velocity occurs along the central axis, decreasing progressively toward the vessel walls, where it reaches zero due to viscous drag.Approximating Blood...

Depressive Disorders: Etiology

Depressive Disorders: Etiology

Depressive disorders result from a complex interplay of biological, psychological, and sociocultural factors, each contributing uniquely to the development and persistence of the condition. Understanding these factors provides critical insight into the multifaceted nature of depression.
Biological Factors in Depression
Biological predispositions significantly influence the risk of developing depressive disorders. Genetic studies highlight the role of variations in the serotonin transporter...
