Prolonging healthy aging: Longevity vitamins and proteins.

Authors:
Bruce N Ames

Proc Natl Acad Sci U S A 2018 10 15;115(43):10836-10844. Epub 2018 Oct 15.

Nutrition and Metabolism Center, Children's Hospital Oakland Research Institute (CHORI), Oakland, CA 94609-1809

It is proposed that proteins/enzymes be classified into two classes according to their essentiality for immediate survival/reproduction and their function in long-term health: that is, survival proteins versus longevity proteins. As proposed by the triage theory, a modest deficiency of one of the nutrients/cofactors triggers a built-in rationing mechanism that favors the proteins needed for immediate survival and reproduction (survival proteins) while sacrificing those needed to protect against future damage (longevity proteins). Impairment of the function of longevity proteins results in an insidious acceleration of the risk of diseases associated with aging. Read More

Intrathecal chemotherapy may be complicated with the development of myelopathies or toxic radiculopathies. This myeloradicular involvement, of toxic character, is unpredictable, since these patients have repeatedly received Intrathecal chemotherapy with the same drugs without apparent injury. The toxic effect should be mainly attributed to Cytarabine and not to methotrexate, since the central nervous system lacks Cytidine deaminase, the enzyme that degrades Cytarabine. Read More

The high cardiovascular mortality associated with chronic kidney disease (CKD) is caused in part by the CKD-mineral bone disorder (CKD-MBD) syndrome. The CKD-MBD consists of skeletal, vascular and cardiac pathology caused by metabolic derangements produced by kidney disease. The prevalence of osteopenia/osteoporosis resulting from the skeletal component of the CKD-MBD, renal osteodystrophy (ROD), in patients with CKD exceeds that of the general population and is a major public health concern.
