Runx1-Stat3 signaling regulates the epithelial stem cells in continuously growing incisors

open access: yesScientific Reports, 2018
Rodent incisors grow permanently and the homeostasis of enamel production is maintained by a continuous supply of epithelial progenitors from putative stem cells in the cervical loop.

A reappraisal of the Middle to Later Stone Age prehistory of Morocco Réévaluer la préhistoire du Maroc, du Middle Stone Age au Later Stone Age

open access: yesJournal of the Royal Anthropological Institute, EarlyView.
Over the last 25 years, perceptions of the early prehistory of Northwest Africa have undergone radical changes due to new fieldwork projects and a corresponding growth in scientific interest in the region. Much of this work has been focused in Morocco, known for its extremely rich fossil and archaeological records in caves and rock shelters.

Supra and subgingival application of antiseptics or antibiotics during periodontal therapy

open access: yesPeriodontology 2000, EarlyView., 2023
Abstract Periodontal diseases (gingivitis and periodontitis) are characterized by inflammatory processes which arise as a result of disruption of the balance in the oral ecosystem. According to the current S3 level clinical practice guidelines, therapy of patients with periodontitis involves a stepwise approach that includes the control of the patient ...

The effectiveness of using carbonate isotope measurements of body tissues to infer diet in human evolution: Evidence from wild western chimpanzees (Pan troglodytes verus)* [PDF]

open access: yes, 2015
Changes in diet throughout hominin evolution have been linked with important evolutionary changes. Stable carbon isotope analysis of inorganic apatite carbonate is the main isotopic method used to reconstruct fossil hominin diets; to test its ...

The effect of different salivary calcium concentrations on the erosion protection conferred by the salivary pellicle

open access: yesScientific Reports, 2017
Different proportions of mineral ions in saliva can influence the protective effect the salivary pellicle provides against dental erosion. To investigate the effect of different calcium concentrations in human saliva on the protection against enamel ...

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

open access: yesInsect Science, EarlyView.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Preliminary Resin Infiltration of Hypomineralised Enamel for Posterior Indirect Adhesive Restoration: An Innovative Approach

open access: yesAustralian Dental Journal, EarlyView.
ABSTRACT Hypomineralised enamel presents a significant challenge for resin bonding due to its altered mechanical and structural properties. Our innovative clinical approach of resin infiltration prior to the bonding of a posterior indirect adhesive restoration aims to preserve dental tissues, reduce post‐operative sensitivity, and strengthen the ...

FAM20A Deficiency Drives Transcriptomic Dysregulation and Functional Impairment in Gingival Fibroblasts

open access: yesCell Proliferation, EarlyView.
FAM20A variants cause AI1G, marked by enamel defects, gingival overgrowth and ectopic calcifications. RNA sequencing of patient‐derived gingival fibroblasts showed dysregulated genes in adhesion, proliferation and signalling pathways. Functional assays revealed increased cell proliferation, impaired ECM interactions and osteogenesis, suggesting FAM20A ...

Kdf1 Regulates Molar Cusp Morphogenesis via the PI3K/AKT/mTOR Signalling Axis

open access: yesCell Proliferation, EarlyView.
Epithelial Kdf1 knockout disrupts molar cusp morphogenesis by promoting inner enamel epithelium proliferation and invagination via PI3K/AKT/mTOR signalling. ABSTRACT Keratinocyte differentiation factor 1 (Kdf1) reportedly plays a significant role in enamel formation.
