OBJECTIVE A recent study concerning high-altitude pulmonary edema (HAPE), a non-cardiogenic pulmonary edema, suggested that it is initially a hydrostatic-type pulmonary edema. We suspect that some extent of cardiac insufficiency may likely relate to the mechanism of the development of this disease. METHODS By Doppler echocardiography, the Tei index (a new quantitative index proposed for the e...

Hypoxia causes an increase in pulmonary artery pressure. Gene expression controlled by the hypoxia-inducible factor (HIF) family of transcription factors plays an important role in the underlying pulmonary vascular responses. The hydroxylase enzymes that regulate HIF are highly sensitive to varying iron availability, and iron status modifies the pulmonary vascular response to hypoxia, possibly ...

Objective: We aimed to investigate the association of systolic pulmonary artery pressure (sPAP), with diameter (PAD), age, gender, disease duration, stages, extrapulmonary involvement, and spontaneous remission in patients sarcoidosis. Materials Methods: Diagnosed followed-up chest diseases clinic between 2010-2020, 60 sarcoidosis were included. Patients’ demographic data, clinical course, info...

Pulmonary hypertension and cor pulmonale have been shown to worsen prognosis increase the risk of death in adult patients with cystic fibrosis (CF). To evaluate arterial stiffness (AS) functional state left right parts heart CF patients. 50 (25 M/ 25 F, mean age 26 ± 6 yrs) 52 volunteers (20 32 27 were examined. Echocardiography was performed only AS measurements using VaSera VS-1500N: cardio-a...

For a new city that is committed to promoting Electric Vehicles (EVs), it significant plan the public charging infrastructure where demands are high. However, difficult predict before actual deployment of EV chargers for lack operational data, resulting in deadlock. A direct idea leverage urban transfer learning paradigm learn knowledge from source city, then exploit demands, and meanwhile dete...

BACKGROUND We assessed late outcome after tricuspid annuloplasty (TAP) using a flexible band or ring for functional tricuspid regurgitation (FTR). METHODS AND RESULTS We reviewed 220 consecutive patients (mean age, 65.4±11.4 years) who underwent TAP for FTR during mitral valve surgery between January 2000 and December 2010. Indications for TAP included the following: (1) TR grade greater than...

Aims: Mutans streptococci include Streptococcus mutans and sobrinus, which can cause tooth decay. The current study aimed to compare their virulence genes with each other correlate them the clinical data of patients. Materials methods: Altogether 21 S. 19 sobrinus strains were investigated, originating from 24 children (age 2.7 ± 0.4 years) 13 mothers (27.3 3.7). PCR method was applied detect 1...

The present study aimed to evaluate hemodynamics and right ventricular function in patients with pulmonary hypertension (PH) using transthoracic echocardiography and to compare these results with measurements obtained using right‐sided heart catheterization (RHC). A total of 75 patients with PH were examined using echocardiography and RHC. Patients were divided into the following two groups acc...
