Hypoxia and pulmonary arterial pressure in the rabbit

The Journal of Physiology, 1969
1. The effect of hypoxia on pulmonary arterial pressure was studied in young and adult rabbits.2. In isolated perfused lungs, hypoxia caused no rise in pulmonary arterial pressure in rabbits on the day of birth. The size of the hypoxic response increased progressively until 9–11 days of age, when the adult response of a 20% rise of pulmonary arterial ...

Pulmonary Artery Pressure in Lymphangioleiomyomatosis [PDF]

Chest, 2007
Exercise-induced hypoxemia is frequent in patients with lymphangioleiomyomatosis (LAM) and could be associated with pulmonary hypertension. The aims of this study were to determine the prevalence of pulmonary hypertension in patients with LAM, to identify physiologic parameters associated with its occurrence, and to evaluate the effect of oxygen on ...

Rapid Blood Clot Removal via Remote Delamination and Magnetization of Clot Debris

Advanced Science, EarlyView.
A programmable colloidal microswarm is developed to quickly detach blood clots and enable rapid recanalization, with the detached debris functioning as a magnetic “debris‐robot” that can be efficiently propelled and retrieved via catheter suction, which could significantly save time compared to the critical “Golden 6 hours” window for ischemic stroke ...

Single Test‐Based Diagnosis and Subtyping of Pulmonary Hypertension Caused by Fibrosing Mediastinitis Using Plasma Metabolic Analysis

Advanced Science, EarlyView.
Pulmonary hypertension caused by fibrosing mediastinitis has a five‐year survival rate of just 56%. Current diagnostic approaches are complex for patients with mobility limitations and can lead to misdiagnoses due to their nonspecific clinical features.

The Influence of the Pulmonary Arterial Pressure on the Pulmonary Capillary Venous Pressure in Man [PDF]

Circulation Research, 1953
In two cases with a well-defined pulmonary capillary venous pressure pulse, the lobular pulmonary artery was occluded with a balloon while the pulmonary capillary venous pressure was registered. There was no change in the tracing obtained. In two other cases positive pressure respiration almost completely damped out the pulmonary capillary venous ...

Decursin‐Loaded Nanovesicles Target Macrophages Driven by the Pathological Process of Atherosclerosis

Advanced Science, EarlyView.
This study presents decursin, a traditional Chinese medicine monomer, that inhibits lipid accumulation and inflammation in atherosclerosis through PKCδ interaction. A novel targeted delivery system (ALD@EM) is developed to overcome decursin's short half‐life, combining antibody‐mediated targeting, LDL‐facilitated chemotaxis, and enhanced macrophage ...

Association between Splenectomy and Pulmonary Hypertension in Patients with Major Beta- Thalassemia

Journal of Mazandaran University of Medical Sciences, 2017
Background and purpose: Increased pressure in the pulmonary circulation is of the major factors causing cardiac disorders in patients with thalassemia. The aim of this study was to investigate the relationship between splenectomy and pulmonary arterial ...

Echocardiography versus right heart catheterization in class I pulmonary hypertension

Egyptian Journal of Chest Disease and Tuberculosis, 2014
It has been agreed that pulmonary hypertension should be determined by right heart catheterization. However, being invasive and refused by many patients, echocardiography was thought to be a reasonable substitute to determine a solid diagnosis of ...
