Abstract

Area dorsalis pars lateralis was shown to be subdivided into a dorsal region and a ventral region by a shallow groove on the telencephalic surface. In the dorsal region, three layers were distinguished by Nissl staining; a surface layer I, a middle layer II, and a deep layer III. Although a three-layered structure was also observed in the ventral region, it was not as clear as that in the dorsal region. Cells in area dorsalis pars lateralis were classified by Golgi-Cox staining into 5 types; small cells, horizontal cells, pyriform cells, inverted cells, and multipolar cells. The distribution of zinc was examined by the Neo-Timm method and found to be present in layers I and II and weakly in layer III of the dorsal region but not in layers I and II of the ventral region. The presence of zinc in synaptic terminals in the dorsal region was verified by analytical electron microscopy. Following separate and localized injections of horseradish peroxidase into dorsal and ventral regions, some different fiber connections were revealed. Both dorsal and ventral regions had reciprocal connections with ipsilateral area dorsalis pars centralis, area ventralis pars supracommissuralis, area ventralis pars dorsalis, area ventralis pars posteri...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.
