- 心血管生理学和病理生理学.
- 基因组学和分子生物学.
背景情况:
- 孕前的发病过程涉及母亲和胎儿因子之间的复杂相互作用.
- 胎盘和母体心血管系统在孕前的作用受到辩论.
- 现有研究强调了胎盘功能障碍和心血管适应不良.
研究的目的:
- 提出一个关于产前发展的综合模型.
- 为了调和不同的孕前表型及其拟议的起源.
- 定义两种不同类型的孕前:I型和II型.
主要方法:
- 开发一个集成的心脏 - 胎盘 - 胎儿阵列模型.

- 对基因表达模式的单细胞转录学调查.
主要成果:
- I型孕前:早期发病,胎盘功能障碍,高血管抵抗,低心脏输出,经常伴有胎儿生长限制.
- 二型孕前:晚期发病,母体心血管不耐受,血管抵抗性低,心脏输出量高,可能伴有胎儿宏观症.
- 分子分析揭示了广泛的基因失调和可溶性fms-like-tyrosine kinase-1 (sFLT1) 和胎盘生长因子 (PlGF) 的不平衡,特别是在I型.

Diabetes Mellitus: Type 2 and Gestational
2.5K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

Nephrotic Syndrome II : Assessment and Medical Management
8
IntroductionNephrotic syndrome is a kidney disorder marked by excessive protein loss in the urine, leading to various systemic complications. This condition often results from damage to the glomeruli—the kidney's filtering units—causing proteinuria, low blood protein levels, and fluid retention. Understanding the assessment, diagnosis, and management of nephrotic syndrome is essential for effective treatment and prevention of further kidney damage.AssessmentPatient History: Document...

Pathophysiology of Diabetes
956
Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

Hypertension III: Clinical Manifestations and Diagnostic Studies
15
Hypertension is asymptomatic and also referred to as the "silent killer" until it progresses to a severe stage or causes target organ disease. Patients may experience symptoms stemming from the strain on blood vessels and tissues in various organs or the heart's increased workload.Physical exams might show no abnormalities other than high blood pressure. Signs of vascular damage, when present, correspond to the organs supplied by the affected vessels, leading to target organ damage. For...

Peripheral Arterial Disease II: Clinical Manifestations and Diagnostic Evaluation
14
Clinical manifestationsPeripheral Arterial Disease (PAD) manifests through a range of symptoms, from the characteristic intermittent claudication to atypical presentations and severe complications in advanced stages. Intermittent claudication, a hallmark symptom of PAD, presents as exercise-induced muscle pain that typically resolves within minutes of rest. This pain is reproducible and stems from inadequate blood flow, leading to the accumulation of lactic acid produced during anaerobic...

Diabetes Mellitus: Overview and Type I Subtype
2.7K
Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
