Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny

The Anatomical Record, EarlyView.
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Evolutionary radiation of large‐bodied gorgonopsians from the lower Abrahamskraal formation of South Africa

The Anatomical Record, EarlyView.
Abstract The middle Permian represents a critical interval in therapsid evolution, when gorgonopsians emerged as some of the first specialized apex predators within terrestrial ecosystems. Despite their significance, the early diversification of Gorgonopsia in Gondwana remains poorly understood due to scarcity and fragmentary material.

Pointer Race Freedom

, 2015
We propose a novel notion of pointer race for concurrent programs manipulating a shared heap. A pointer race is an access to a memory address which was freed, and it is out of the accessor's control whether or not the cell has been re-allocated.

Isotropic Elastic and Plastic Deformation in Parallel Rheological Framework Models

Journal of Mechanical Engineering
This paper deals with the calibration of the polymer material PPC3TF2 using the PRF (Parallel Rheological Framework) material model implemented in the commercial software Abaqus. In order to reduce computational time, the unit cube model was used for the

Effects of an injectable platelet-rich fibrin on osteoblast behavior and bone tissue formation in comparison to platelet-rich plasma

Platelets, 2018
Platelet-rich plasma (PRP) has been utilized for many years as a regenerative agent capable of inducing vascularization of various tissues using blood-derived growth factors. Despite this, drawbacks mostly related to the additional use of anti-coagulants

PRF in der Zahnmedizin

SWISS DENTAL JOURNAL SSO – Science and Clinical Topics, 2018
Platelet-rich-Fibrin (PRF) bezieht sich auf einen Bestandteil des natürlichen Blutes. Die sogenannte Fibrinmatrix ist angereichert mit Blutplättchen (Thrombozyten). Die Herstellung ermöglicht den Gewinn von PRF in Form einer Matrix oder eines Gels aus dem eigenen Blut und anschliessend die Applikation an entsprechend gewünschter Region.

Management of severe bone loss in patients at risk of medication‐related osteonecrosis of the jaw with microsurgery and guided bone regeneration: A case study

Clinical Advances in Periodontics, EarlyView.
Abstract Background Medication‐related osteonecrosis of the jaw (MRONJ) is a challenging complication associated with antiresorptive medications. Its exact pathophysiology remains unclear, but dental extractions and infections are known triggers, complicating prevention, and treatment.

Growth factor and pro-inflammatory cytokine contents in platelet-rich plasma (PRP), plasma rich in growth factors (PRGF), advanced platelet-rich fibrin (A-PRF), and concentrated growth factors (CGF)

International Journal of Implant Dentistry, 2016
BackgroundThe development of platelet-rich fibrin (PRF) drastically simplified the preparation procedure of platelet-concentrated biomaterials, such as platelet-rich plasma (PRP), and facilitated their clinical application.
