Testicular vascular permeability: effects of experimental lesions associated with impaired testis function

The Journal of Urology
T T TurnerC P Rhoades

Abstract

Pathologies like varicocele and testicular torsion are known to alter testicular blood flow, either acutely or chronically. The present study was undertaken to determine whether or not alterations in testicular vascular permeability accompany these changes in testicular blood flow. Testicular vascular permeability was examined by determining the appearance of radiolabelled molecules (m.w. = 18 to 70,000) in testicular interstitial fluid after acute infusion into the proximal testicular artery of the rat. These vascular permeability studies were carried out in control animals, in those with 30 day experimental left varicocele (ELV), or in those having experienced a 1 hour, 720 degrees experimental torsion either 1 hour or 24 hours prior to the study. Experimental left varicocele did not alter vascular permeability to the molecules studied, but 1 hour torsion did cause a significant increase in vascular permeability within 24 hours after repair of the torsion. Alteration in vascular permeability is one of the family of events contributing to cell death after repair of experimental testicular torsion, but is not a factor in the pathobiology of experimental varicocele.

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.
