Clinical Study to Individual Treatment for Major Aortopulmonary Collaterals of Tetralogy of Fallot

open access: yesBioMed Research International, Volume 2019, Issue 1, 2019., 2019
Objectives. To build a guideline for the individual treatment of Tetralogy of Fallot (TOF) with major aortopulmonary collaterals (MAPCAs) and tentatively establish the occlusion index of MAPCAs. Methods. According to the diameter of the aortopulmonary collaterals (R: mm) and the bodyweight of the children (weight: kg), K= ((∑R2)/Wt) was set as the ...

A Bibliometric Analysis of Study of Associations of Certain Genotypes with the Cardiovascular Form of Diabetic Neuropathy

open access: yesBioMed Research International, Volume 2024, Issue 1, 2024.
This bibliometric analysis explores the landscape of research on the associations between specific genotypes and the cardiovascular form of diabetic neuropathy. Diabetes mellitus (DM) is a major contributor to premature mortality, primarily due to increased susceptibility to cardiovascular diseases.

Tetramethylpyrazine Prevents Contrast‐Induced Nephropathy via Modulating Tubular Cell Mitophagy and Suppressing Mitochondrial Fragmentation, CCL2/CCR2‐Mediated Inflammation, and Intestinal Injury

open access: yesOxidative Medicine and Cellular Longevity, Volume 2019, Issue 1, 2019., 2019
Contrast‐induced nephropathy (CIN) is a leading cause of hospital‐acquired acute kidney injury (AKI), but detailed pathogenesis and effectual remedy remain elusive. Here, we tested the hypothesis that contrast media (CM) impaired mitochondrial quality control (MQC) in tubules, including mitochondrial fragmentation and mitophagy, induced systemic ...
