Rod‐shaped Polymerized Salicylic Acid Particles Modulate Neutrophil Transendothelial Migration in Acute Inflammation

open access: yesAdvanced Healthcare Materials, EarlyView.
Rod‐shaped particles outperform spherical particles of the same volume in preventing neutrophil infiltration to inflamed areas, both in vitro and in vivo. This therapeutic effectiveness is attributed to better cell targeting and decreased cell motility, resulting from the geometry‐driven phagocytosis and inhibited actin polymerization.

New insights into Neolithic milk consumption through proteomic analysis of dental calculus

open access: yesArchaeological and Anthropological Sciences, 2019
There has long been debate over the origins of dairy consumption within European populations. Whilst it was previously assumed that lactase persistence (LP) was under positive selection following the advent of agriculture, recent genetic studies of ...

A Wireless Cortical Surface Implant for Diagnosing and Alleviating Parkinson's Disease Symptoms in Freely Moving Animals

open access: yesAdvanced Healthcare Materials, EarlyView.
A wireless cortical surface implant employing graphene electrode arrays diagnoses and alleviates Parkinson's disease symptoms in freely moving animals. The device continuously monitors cortical activity and delivers targeted stimulation, restoring beta–gamma and delta oscillations.

Design of quantum correlation based automatic focus detection system during dental laser operation [PDF]

open access: yesarXiv, 2019
Dental laser has been developed recently and gradually replaced the conventional dental treatment methods, especially in dental caries removal. The utility of laser in dentistry contributes to reduce the pain during surgery and decrease the risk of sequelae after surgery.

Automatic Recognition of Landmarks on Digital Dental Models [PDF]

open access: yesarXiv, 2020
Fundamental to improving Dental and Orthodontic treatments is the ability to quantitatively assess and cross-compare their outcomes. Such assessments require calculating distances and angles from 3D coordinates of dental landmarks. The costly and repetitive task of hand-labelling dental models impedes studies requiring large sample size to penetrate ...

Supragingival calculus: Formation and control [PDF]

open access: yes, 2002
Dental calculus is composed of inorganic components and organic matrix. Brushite, dicalcium phosphate dihydrate, octacalcium phosphate, hydroxyapatite, and whitlockite form the mineral part of dental calculus.

Influence of Hypoxia on a Biomaterial Model of the Bone Marrow Perivascular Niche

open access: yesAdvanced Healthcare Materials, EarlyView.
Hypoxia is a key factor in bone marrow physiology and hematopoietic stem cell behavior. Lower oxygen tension influences the secretion of vasculature‐derived hematopoietic regulatory factors and alters hematopoietic cell behavior in a conditioned medium hydrogel model of bone marrow. Cyclosporin A is used to mitigate normoxic stress during hematopoietic

Multifunctional Neural Probes Enable Bidirectional Electrical, Optical, and Chemical Recording and Stimulation In Vivo

open access: yesAdvanced Materials, EarlyView.
Convergence drawing is used to create flexible, microscale, multifunctional fiber‐based neural probes. Optimized materials selection enables individual devices to perform neural recording, electrical stimulation, optogenetics, fiber photometry, fluid delivery, and voltammetric neurotransmitter detection in rodents.

Effects of stabilized stannous fluoride dentifrice on dental calculus, dental plaque, gingivitis, halitosis and stain: A systematic review

open access: yesHeliyon, 2019
Objectives: The aim of the present systematic review was to examine the scientific evidence for the efficacy of stabilized stannous fluoride (SnF2) dentifrice in relation to dental calculus, dental plaque, gingivitis, halitosis and staining.

Dental calculus and isotopes provide direct evidence of fish and plant consumption in Mesolithic Mediterranean

open access: yesScientific Reports, 2018
In this contribution we dismantle the perceived role of marine resources and plant foods in the subsistence economy of Holocene foragers of the Central Mediterranean using a combination of dental calculus and stable isotope analyses.
