Summary
Preeclampsia, a pregnancy complication, may stem from placental issues and oxidative stress. This review explores oxidative stress
Area of Science:
- Obstetrics and Gynecology
- Maternal-Fetal Medicine
- Pathophysiology of Pregnancy Complications
Background:
- Preeclampsia affects 3-7% of pregnancies, posing significant maternal risks.
- Its exact pathophysiology remains unclear, but a two-stage model implicates placental dysfunction.
- Systemic inflammation and endothelial dysfunction characterize maternal symptoms in preeclampsia.
Purpose of the Study:
- To review the current understanding of preeclampsia etiology.
- To focus on the role of oxidative stress in preeclampsia.
- To examine factors causing endothelial dysfunction and antioxidant trials in preeclampsia.
Main Methods:
- Literature review of preeclampsia pathophysiology.
- Analysis of studies on oxidative stress and endothelial dysfunction.
- Evaluation of clinical trials on antioxidant supplementation.
Main Results:
- Oxidative stress is a key factor in preeclampsia pathophysiology.
- Placental hypoperfusion releases factors leading to maternal symptoms.
- Endothelial dysfunction is a central mechanism in preeclampsia development.
Conclusions:
- Oxidative stress presents a unifying hypothesis for preeclampsia etiology.
- Understanding oxidative stress mechanisms may reveal new therapeutic targets.
- Further research into antioxidant therapies for preeclampsia is warranted.

37.1K
The renin-aldosterone system is an endocrine system which guides the renal absorption of water and electrolytes, thus managing blood pressure and osmoregulation. Activation of the system begins in the kidneys with a small cluster of cells adjacent to the afferent and efferent blood vessels of the renal corpuscle. As the nephrons are filtering blood, juxtaglomerular cells monitor blood pressure. If they detect a decrease in pressure, they release the hormone renin into the bloodstream.

Peroxisomes are specialized organelles present in fungi, plant, and animal cells. It can vary in number, size, morphology, and activity depending on the type of tissue and the nutritional state of the cell. For example, cells with active lipid metabolism, such as adipocytes, neurons, and hepatocytes, have more peroxisomes than other cells in the body. Besides their primary role in breaking down complex organic molecules, peroxisomes can also synthesize specific macromolecules and participate in...

665
Psychoneuroimmunology (PNI) is a multidisciplinary field that examines how psychological factors, particularly stress, interact with the immune system and impact physical health. Research in PNI has shown that chronic or traumatic stress can disrupt both the hypothalamic-pituitary-adrenal axis and the sympathetic nervous system. These disruptions contribute to serious health conditions, including cardiovascular diseases.
A key area of focus in PNI is the relationship between stress and coronary...

1.5K
Hypertension is a chronic condition in which the blood's force against artery walls is excessively high, posing risks such as heart disease. The condition's underlying mechanisms involve complex interactions among the cardiovascular, kidney, and autonomic nervous systems.Renin-Angiotensin-Aldosterone System (RAAS): This system significantly influences blood pressure regulation. When blood pressure decreases, the kidneys secrete renin. This enzyme transforms angiotensinogen, a plasma protein,...
