Bone Healing Around Implants in Normal and Medically Compromised Conditions: Osteoporosis and Diabetes

Advanced Healthcare Materials, EarlyView.
xx xx. ABSTRACT Osseointegration of orthopedic and dental implants is influenced by local and systemic factors, including their physicochemical surface properties and the patient's overall health status. Titanium and its alloys have been a longstanding standard for bone implants due to their innate biocompatibility and mechanical properties.

ATP as a presynaptic modulator [PDF]

, 2000
© 2000 Elsevier Science Inc.There is considerable evidence that ATP acts as a fast transmitter or co-transmitter in autonomic and sensory nerves mostly through activation of ionotropic P2X receptors but also through metabotropic P2Y receptors. By analogy,

Post-thyroidectomy hypothyroidism increases the expression and activity of ectonucleotidases in platelets: Possible involvement of reactive oxygen species

Platelets, 2018
Signaling mediated by purines is a widespread mechanism of cell–cell communication related to vasomotor responses and the control of platelet function in the vascular system. However, little is known about the involvement of this signaling as well as the

ENTPDase inhibitors: therapeutic potential in infectious, inflammatory, and neuroinflammatory diseases [PDF]

Exploration of Neuroscience
Ectonucleoside triphosphate diphosphohydrolases (ENTPDases), members of the cluster of differentiation 39 (CD39) family, are key regulators of purinergic signaling through the hydrolysis of tri and diphosphate nucleotides.
