Abstract

We conducted a systematic macroscopic and microscopic examination of occlusal and para-occlusal wear in a large dental sample (n = 3,014) from 217 individuals dated to the Early Bronze age site of Gricignano d'Aversa, Italy. We used macroscopic and microscopic techniques to document nondietary occlusal and para-occlusal wear and to analyze calculus inclusions in some of the teeth. In combining an analysis of the wear with the calculus inclusions we linked the specific wear to the likely fiber that was involved in producing it. Teeth and their high resolution epoxy casts were analyzed through SEM and reflected light microscopes. Nineteen individuals (fifteen with activity induced dental modifications and four as a control sample) were examined for the presence of calculus inclusions. Activity induced dental modifications (AIDMs), notches, grooves and micro-striations, were found in the 62.2% of the adult females, in 21.2% of the adults of unknown sex and in a single male. We found the full spectrum of dental manipulations from very minor nonocclusal wear in some young individuals to severe attrition at the other extreme. The width of the striations and grooves, mostly on the upper incisors, suggests a craft activity involving fi...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.
