Dental Developmental Defects: A Pilot Study to Examine the Prevalence and Etiology in a Population of Children between 2 and 15 Years of Age

open access: yesDentistry Journal
Dental development defects (DDDs) are quantitative and/or qualitative alterations produced during odontogenesis that affect both primary and permanent dentition.

Mineralized area of the human rib cross‐sections from early puberty until adulthood

open access: yesThe Anatomical Record, EarlyView.
Abstract Ribs undergo numerous changes during growth and development. Although they occur both externally and internally, the latter are not as extensively documented during the transition from puberty to adulthood. Therefore, it is unknown how rib cross‐sectional mineralized area changes during this period.

Commentary: What's so interesting about sabertooths?

open access: yesThe Anatomical Record, EarlyView.
Abstract Sabertooth creatures are fascinating to the public and to scientists. This Special Issue on The Anatomy of Sabertooths starts with a discussion of what exactly a sabertooth is, continues with a couple of papers about other animals with extraordinarily long teeth, and then delves into analyses of fossil sabertoothed taxa—some of which are not ...

Revisiting paravertebral muscles in European rabbits (Oryctolagus cuniculus) and European brown hares (Lepus europaeus) (Leporidae; Lagomorpha)

open access: yesThe Anatomical Record, EarlyView.
Abstract Domesticated European rabbits (Oryctolagus cuniculus) have long been chosen as laboratory model organisms. Despite this, there has been no definitive study of the vertebral musculature of wild rabbits. Relevant descriptions of well‐studied veterinary model mammals (such as dogs) are generally applicable, but not appropriate for a species ...

Prospective Memory Performance of Autistic Adults in Everyday Life: The Role of Stress and Motivation

open access: yesAutism Research, EarlyView.
ABSTRACT Prospective memory (PM) is the ability to remember to carry out intended actions in the future. The present study investigated the PM performance of autistic adults in everyday life. A total of 29 autistic participants and 30 controls matched for age, gender, and cognitive abilities completed various PM tasks (time‐based vs.

How to estimate dental age in paleodontology? [PDF]

open access: yes, 2010
Nowadays there are many methods available for dental age estimation: morphological, radiological, biochemical. Some methods require sample sectioning while other non-destructive methods are more appropriate for use in paleodontology.

Physics of Protein Aggregation in Normal and Accelerated Brain Aging

open access: yesBioEssays, EarlyView.
Soluble monomeric proteins precipitate via nucleation into insoluble amyloids in response to age‐related exposures (e.g., microbes, nanoparticles). Persistent soluble‐to‐insoluble phase transition depletes the functional proteins. In normal aging, replacement matches loss; in accelerated aging, it does not.
