Changes in lung mechanics and ventilation-perfusion match: comparison of pulmonary air- and thromboembolism in rats

BMC Pulmonary Medicine
Background Pulmonary air embolism (AE) and thromboembolism lead to severe ventilation-perfusion defects. The spatial distribution of pulmonary perfusion dysfunctions differs substantially in the two pulmonary embolism pathologies, and the effects on ...

A Multivariable Index for Grading Exercise Gas Exchange Severity in Patients with Pulmonary Arterial Hypertension and Heart Failure

Pulmonary Medicine, 2012
Patients with pulmonary arterial hypertension (PAH) and heart failure (HF) display many abnormalities in respiratory gas exchange. These abnormalities are accentuated with exercise and track with disease severity.

PATHOLOGIC PHYSIOLOGY OF EXACERBATIONS OF CHRONIC OBSTRUCTIVE PULMONARY DISEASE

Вестник анестезиологии и реаниматологии, 2019
The lecture describes the mechanisms of deterioration of respiratory exchange during exacerbation of chronic obstructive pulmonary disease (COPD). It has been demonstrated that the rapid diagnosis and treatment of exacerbations is an important part of ...

Hypoxic pulmonary vasoconstriction and gas exchange in acute canine pulmonary embolism.

, 1996
Hypoxic pulmonary vasoconstriction (HPV) is inhibited in several models of acute lung injury. Whether HPV is preserved in pulmonary embolism is unknown.

Organoid Brain‐Machine‐Interface Devices for Central Nervous System Repair

Advanced Science, EarlyView.
We envision organoid brain‐machine‐interface (Organoid‐BMI) devices as new biohybrid bidirectional communication pathways to connect the human CNS and the external world for personalized CNS repair and regeneration. ABSTRACT Central nervous system (CNS) repair and regeneration suffer from tremendous clinical challenges due to current limitations in ...

Caveolin‐1 Stabilizes SERCA2 to Counteract Acute Kidney Injury via Suppression of Ca2+‐Dependent Endoplasmic Reticulum Stress in Distal Tubules

Advanced Science, EarlyView.
In AKI, initial kidney injury upregulates the expression of Cav‐1, which subsequently binds to and stabilizes SERCA2 via its scaffolding domain and through deubiquitination, thereby regulating Ca2+ homeostasis and ER stress. Conversely, Cav‐1 deficiency accelerates SERCA2 degradation, triggering Ca2+ overload and ER stress, and ultimately exacerbating ...

Subxyphoid pleural drain confers lesser impairment in respiratory muscle strength, oxygenation and lower chest pain after off-pump coronary artery bypass grafting: a randomized controlled trial Dreno pleural subxifoide confere menor comprometimento da força muscular respiratória, oxigenação e menor dor torácica após cirurgia de revascularização do miocárdio sem circulação extracorpórea: estudo controlado randomizado

Brazilian Journal of Cardiovascular Surgery, 2012
OBJECTIVE: To evaluate respiratory muscle strength, oxygenation and chest pain in patients undergoing off-pump coronary artery bypass (OPCAB) using internal thoracic artery grafts comparing pleural drain insertion site at the subxyphoid region versus the
