Exceptional preservation informs the paleobiology of tapinocephalid dinocephalians

open access: yesThe Anatomical Record, EarlyView.
Abstract The tapinocephalid dinocephalian Moschops is one of the most iconic taxa of the middle Permian, yet its paleobiology remains one of the least well‐known. Here, we address some aspects of paleoneurology and paleobiology of Moschops using CT scanning of four well preserved skulls from the upper Abrahamskraal Formation of South Africa. Two of the

Effect of low-level laser therapy in tooth bleaching sensitivity:

open access: yesRevista da Faculdade de Odontologia de Porto Alegre
Aim: Tooth sensitivity is the principal side effect as a clinical consequence resulting from tooth bleaching. Therefore, several strategies have been proposed to control this adverse effect. The present study aimed to investigate the effect of low-level

Accurate Tooth Lead Crowning without Twist in Cylindrical Helical Gear Grinding

open access: yesAdvances in Mechanical Engineering, 2014
Form grinding is a popular finishing process in manufacturing cylindrical gears with tooth flank modification. The tooth flanks are usually twisted when a lead crowning is performed only through additional radial motion during double flank grinding.

Dissecting the dissection laboratory: Elements for designing a human anatomy laboratory

open access: yesAnatomical Sciences Education, EarlyView.
Abstract The human anatomy dissection laboratory is a critical component of anatomical and medical education. Development, maintenance, and stocking of these laboratory spaces have unique demands, with all of the challenges in running a laboratory with Biosafety Laboratory Level 2 (BSL‐2) classification, housing a large volume of tissues saturated with

Arthroscopic Remplissage With Knotless All‐Suture Anchors and Concomitant Bankart Repair: Technical Considerations

open access: yesArthroscopy Techniques, EarlyView.
Abstract Anterior shoulder instability is common in active patients. Traumatic dislocations may produce Bankart and Hill‐Sachs lesions that increase recurrence risk. In high‐demand individuals, isolated Bankart repair may be insufficient for off‐track or near‐track Hill‐Sachs lesions.

VITAL TOOTH BLEACHING: SENSITIVITY AND PULPAL CONSIDERATIONS

open access: yesThe Journal of the American Dental Association, 1997
For some patients, sensitivity and discomfort follow vital tooth bleaching. Clinical observations, however, suggest these are reversible episodes with no irreversible long-term effects. Using milder peroxide formulations or gels diminishes postoperative discomfort.

Targeting neutrophil extracellular traps in metabolic and immune niche: Nanomaterials for diabetes tissue regeneration

open access: yesBMEMat, EarlyView.
The effects of NETs on regeneration of various diabetic tissues, and strategies targeting NETs for diabetes tissue regeneration. In the diabetic environment, NETs undergo complex metabolic and immune reprogramming, leading to dynamic changes in antibacterial and proinflammatory functions, and affecting regeneration of multiple systemic tissues.
