Abstract

The structure of the palatine salivary glands of rabbits was studied employing scanning electron microscopic methods. The fractured surface of the palatine salivary glands revealed that they were formed of small lobuli separated by interlobular spaces containing numerous bundles of collagen fibers. The NaOH treated specimens showed the organization of the collagen fibrils in their original location. In the interstitial stroma compartment, the collagen fibrils revealed a complex three-dimensional arrangement forming channel-like structures for supporting nerve fibers, small vessels and capillaries. Single groups of acinar cells were clearly demonstrated, and each acinus was enveloped by a characteristic basal lamina showing a sponge-like structure made up of several interconnected meshes of collagen fibrils. Furthermore, taking advantage of the ODO method and field emission scanning electron microscopy, within the cytoplasm of secretory acinar cells numerous organelles were clearly observed in a three-dimensional way such as Golgi complex lamellae, rough endoplasmic reticulum, mitochondria and secretory granules. All these cytoplasmic components revealed their real and microtopographical arrangement in some areas of the acinar c...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.
