Metal complexes involving pyridoxine and pyridoxamine

Solid complexes of pyridoxine with Mn(II) , Cd(II) and Zn(II) have been isolated, as well as compounds containing Cu(II), Ni(II), Co(III), Cd(II) and Zn(II), and pyridoxamine in various protonated forms. Infrared spectra provide evidence for protonation at the pyridine nitrogen site in the complexes, but not in the neutral vitamins and the complexes of anionic pyridoxamine. Thus the complexed vitamins are in zwitterionic forms, with chelation probably occurring through the phenolate oxygen and either the amino or the hydroxy group at the 4' position.

Dietary Strategies to Optimize Wound Healing after Periodontal and Dental Implant Surgery: An Evidence-Based Review

Methods to optimize healing through dietary strategies present an attractive option for patients, such that healing from delicate oral surgeries occurs as optimally as possible with minimal patient-meditated complications through improper food choices. This review discusses findings from studies that have investigated the role of diet, either whole foods or individual dietary components, on periodontal health and their potential role in wound healing after periodontal surgery. To date, research in this area has largely focused on foods or individual dietary components that may attenuate inflammation or oxidant stress, or foster de novo bone formation. These studies suggest that a wide variety of dietary components, including macronutrients and micronutrients, are integral for optimal periodontal health and have the potential to accelerate oral wound healing after periodontal procedures. Moreover, this review provides guidance regarding dietary considerations that may help a patient achieve the best possible outcome after a periodontal procedure.
