Vanda Pinto, PhD, science writer —

Vanda is a biochemist with a PhD in biomedicine from the University of Porto, Portugal. She conducted her postdoctoral research first at the Bristol Medical School, U.K., studying the insulin-PI3K/Akt signaling pathway in diabetic nephropathy, then at the Institute of Molecular Pathology and Immunology of the University of Porto, where her focus was on glycosylation in lupus nephritis and inflammatory bowel disease. She next made the switch to science publishing, handling papers in biochemistry, molecular biology, and immunology.

High WIF-1 Blood Levels May Suggest Poorer PH-LHD Outcomes

Levels of the Wnt inhibitory factor 1 (WIF-1) protein were elevated in the blood of people with pulmonary hypertension (PH) associated with left-sided heart failure, according to a new study. WIF-1 was linked with higher levels of NT-proBNP — a marker of heart failure — as well as several…

Using Oxygen Aids Exercise in PH-HFpEF Patients Without Hypoxemia

Breathing oxygen-enriched air can significantly improve exercise performance in people with pulmonary hypertension (PH) linked to heart failure with preserved ejection fraction (HFpEF), including those who might not use supplemental oxygen, according to a small clinical study. Better blood-oxygen levels and more efficient breathing (exchange of carbon dioxide and…

Low Oxygen Increases Chloride Levels in PASMCs in Animal Study

Higher levels of chloride in pulmonary artery smooth muscle cells (PASMCs) may contribute to the development of pulmonary hypertension (PH) after exposure to low oxygen (hypoxia), a study in a rat model suggested. The study, “Increased intracellular Cl− concentration in pulmonary arterial myocytes is associated with chronic hypoxic…

Higher CDC2 Protein Levels Increase Cell Proliferation in PAH

A protein known as cell division cycle protein 2 (CDC2) enhances the proliferation of pulmonary artery smooth muscle cells — those lining the walls of lung arteries — in people with pulmonary arterial hypertension (PAH), a study reported. Additionally, the increased level of CDC2 in these cells was found…

Moving From Tracleer to Letairis Seen as Safe for PAH Patients

People with stable pulmonary arterial hypertension (PAH) can safely switch from Tracleer (bosentan) to Letairis (ambrisentan) without compromising their heart function or general health status, a study from China reports. PAH patients in Hunan province may also benefit financially by moving from Tracleer to Letairis, as it…
