Abstract

Chronic pulmonary embolism is a rare disease which can occur at first with pulmonary hypertension. In these cases it may be difficult to distinguish between primary pulmonary hypertension. We examined nine patients with Chronic Pulmonary Embolism (CPE) (three females and six males, mean age 45 +/- 13 years, range 21-67 years) and ten patients with Primary Pulmonary Hypertension (PPH) (seven females and three males, mean age 35 +/- 13 years, range 10-56 years) who came to our attention during the years 1973-1986 (mean follow up 3 years). All patients had an electrocardiogram, chest x-ray, echocardiogram, cardiac catheterization with pulmonary angiography; seven patients with CPE and eight with PPH had perfusion lung scans. Progressive dyspnoea was the main feature in all the patients; four out of nine with CPE and none of the ones with PPH had a previous history of thrombophlebitis. In all the patients the electrocardiogram, chest x-ray and echocardiogram showed signs of pulmonary hypertension, so that a clear distinction between the two groups was not possible. Cardiac catheterization showed pulmonary pressure values higher in patients with PPH as compared to the ones with CPE (systolic pressure 96 mmHg vs 70 mmHg, diastolic pr...Continue Reading

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
