Abstract

Previous reports on the fine structure of lizard epidermis are confirmed and extended by SEM and TEM observations of cell differentiation and the form of shed material from the American anole Anolis carolinensis. Attention is drawn to two issues: 1) the tips of the spinules arising from the mature oberhautchen are markedly curved; this morphology can be seen during differentiation; 2) the median keels of scales from all parts of the body show "naked" oberhautchen cells that lack characteristic spinules, but have a membrane morphology comprising a complex system of serpentine microridges. Maderson's ([1966] J. Morphol. 119:39-50) "zip-fastener" model for the role of the shedding complex formed by the clear layer and oberhautchen is reviewed and extended in the light of recent SEM data. Apparently periodic lepidosaurian sloughing permits somatic growth; understanding how the phenomenon is brought about requires integration of data from the organismic to the molecular level. The diverse forms of integumentary microornamentation (MO) reported in the literature can be understood by considering how the cellular events occurring during the renewal phase prior to shedding relate to the emergence of the form-function complex of the β-la...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.
