Primo-vessels as new flow paths for intratesticular injected dye in rats

Abstract

After intratesticular injection of a chromium hematoxylin and fluorescent nanoparticle solution, we found a novel flow path in the abdominal cavity consisting of primo-vessels and primo-nodes. This flow path formed a network that crossed over the surfaces of abdominal organs, and generally linked to the greater omentum and adjacent visceral peritoneum. Some of these structures terminated at organs such as the small intestine and the urinary bladder; occasionally, the network entered the parenchyma of organs. The semitransparent primo-vessels and nodes were wholly or partially stained dark-blue by chromium hematoxylin. Injected nanoparticles were also observed in primo-vessels and nodes as well as the parenchyma of organs which were the site of primo-vessel termination. Transmission electron microscopy showed that the primo-vessels consist of many sinuses (4-6 mum), surrounded by collagen fibers, specific granules, cellular remnants, immune cells, extracellular matrices, and hematopoietic cells. These histological features are completely different from blood and lymph vessels indicating that primo-vessels are novel structures that allow the flow of dye.

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.
