Objective: To compare the diagnostic value between mNGS and conventional tests in suspected pulmonary tuberculosis (PTB) patients with scarce sputum or with negative sputum etiological test results.
Methods: We enrolled eligible patients admitted to our department from 2018 to 2021. Their bronchoalveolar lavage fluid (BALF) and lung biopsy tissue samples were sent for mNGS and conventional tests.
Background: Pulmonary hypertension (PH) represents a threatening pathophysiologic state that can be induced by chronic hypoxia and is characterized by extensive vascular remodeling. However, the mechanism underlying hypoxia-induced vascular remodeling is not fully elucidated.
Methods And Results: By using quantitative polymerase chain reactions, western blotting, and immunohistochemistry, we demonstrate that the expression of N-myc downstream regulated gene-1 (NDRG1) is markedly increased in hypoxia-stimulated endothelial cells in a time-dependent manner as well as in human and rat endothelium lesions.
Hypoxic pulmonary hypertension (HPH) is a challenging lung arterial disorder with remarkably high incidence and mortality, and so far patients have failed to benefit from therapeutics clinically available. Max interacting protein 1-0 (Mxi1-0) is one of the functional isoforms of Mxi1. Although it also binds to Max, Mxi1-0, unlike other Mxi1 isoforms, cannot antagonize the oncoprotein c-Myc because of its unique proline rich domain (PRD).
