Vitamin K2 (Menaquinone) Supplementation And Its Benefits In Cardiovascular Disease, Osteoporosis, And Cancer, Grant S. Buchanan, Md, Thomas Melvin, Brandon Merritt, Charles Bishop, Md, Franklin D. Shuler, Md, Phd

Franklin D. Shuler

Vitamin K is known to play an essential role in the coagulation cascade; however, a growing body of research has found that a subtype of this vitamin, vitamin K2 (menaquinone) may have a beneficial effect in osteoporosis, cardiovascular disease, and cancer. This purpose of this article is to provide a comprehensive review of recent literature regarding menaquinone and its role in human health. This review discusses the physiology of menaquinone, its clinical benefits in cardiovascular disease, osteoporosis, and cancer, and how it may interact with certain medications. The authors conclude that menaquinone supplementation has been shown to improve carboxylation of …


Predicting Human Drug Toxicity And Safety Via Animal Tests: Can Any One Species Predict Drug Toxicity In Any Other, And Do Monkeys Help?, Jarrod Bailey, Michelle Thew, Michael Balls Sep 2016

Predicting Human Drug Toxicity And Safety Via Animal Tests: Can Any One Species Predict Drug Toxicity In Any Other, And Do Monkeys Help?, Jarrod Bailey, Michelle Thew, Michael Balls

Jarrod Bailey, PhD

Animals are still widely used in drug development and safety tests, despite evidence for their lack of predictive value. In this regard, we recently showed, by producing Likelihood Ratios (LRs) for an extensive data set of over 3,000 drugs with both animal and human data, that the absence of toxicity in animals provides little or virtually no evidential weight that adverse drug reactions will also be absent in humans. While our analyses suggest that the presence of toxicity in one species may sometimes add evidential weight for risk of toxicity in another, the LRs are extremely inconsistent, varying substantially for …

Ethical Issues In The Use Of Animals In Biomedical And Psychopharmocological Research, John P. Gluck, Jordan Bell Aug 2016

Ethical Issues In The Use Of Animals In Biomedical And Psychopharmocological Research, John P. Gluck, Jordan Bell

John P. Gluck, PhD

Rationale: The ethical debate concerning the use of animals in biomedical and pharmacological research continues to be replete with misunderstandings about whether animals have moral standing. Objectives: This article briefly reviews the central ethical positions and their relationship to the basic parameters of research regulation from an international perspective. The issues associated with the validation of animal models will then be discussed. Finally, suggestions for empirical ethics research will be presented. Methods: Recent literature reviews were accessed and analyzed. Results: This review summarizes the pertinent ethical and research literature. Conclusions: In summary, regardless of the ethical perspective one favors, there …
