One hundred and eight patients suffering from hypertension due to a unilateral parenchymatous neophropathy were studied over a period of one to eight years after treatment was starded. The aetiologies were diverse: harmonious hypoplasia, segmental hypoplasia, pyelonephritis, reflux nephropathy, hydronephrosis and tuberculosis. Thirty nine patients were treated surgically, with 50% good results. In 82 cases medical treatment was continued for at least a year with a 52% success rate. Such success was recorded in 94% of cases in which beta-blockers were used (38 cases). Surgical success was not dependent upon the period for which hypertension had been present. The best results were seen in cases of hydronephrosis and pyelonephritis and the worst in tuberculosis. Thirteen patients underwent surgery event though there was no unilateral increase in plasma renin levels. Seven were improved or cured. Ten patients underwent surgery with a renin activity 50% greater than on the healthy side, 9 being improved or cured. Treatment with beta-blockers, alone or in association with diuretics, controlled blood pressure in 90% of cases, regardless of the renin activity. Plasma renin activity in the renal veins is of good prognostic value in term...Continue Reading

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.

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.

Synapse Loss as Therapeutic Target in MS

As we age, the number of synapses present in the human brain starts to decline, but in neurodegenerative diseases this occurs at an accelerated rate. In MS, it has been shown that there is a reduction in synaptic density, which presents a potential target for treatment. Here is the latest research on synapse loss as a therapeutic target in MS.

Artificial Intelligence in Cardiac Imaging

Artificial intelligence (ai) techniques are increasingly applied to cardiovascular (cv) medicine in cardiac imaging analysis. 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.

Cell Atlas of the Human Eye

Constructing a cell atlas of the human eye will require transcriptomic and histologic analysis over the lifespan. This understanding will aid in the study of development and disease. Find the latest research pertaining to the Cell Atlas of the Human Eye here.

Single Cell Chromatin Profiling

Techniques like ATAC-seq and CUT&Tag have the potential to allow single cell profiling of chromatin accessibility, histones, and TFs. This will provide novel insight into cellular heterogeneity and cell states. Discover the latest research on single cell chromatin profiling here.
