Management of diabetes mellitus in patients with chronic kidney disease

Hahr and Molitch Clinical Diabetes and Endocrinology (2015) 1:2 DOI 10.1186/s40842-015-0001-9 Management of diabetes mellitus in patients withchronic kidney disease Allison J. Hahr and Mark E. Molitch* Glycemic control is essential to delay or prevent the onset of diabetic kidney disease. There are a number ofglucose-lowering medications available but only a fraction of them can be used safely in chronic kidney diseaseand many of them need an adjustment in dosing. The ideal target hemoglobin A1c is approximately 7 % but thistarget is adjusted based on the needs of the patient. Diabetes control should be optimized for each individualpatient, with measures to reduce diabetes-related complications and minimize adverse events. Overall care ofdiabetes necessitates attention to multiple aspects, including reducing the risk of cardiovascular disease, and often,multidisciplinary care is needed.

Chapter 3 - media components and preparation

Media Components The selection or development of the culture medium is vital to success in tissue culture. No single medium will support the growth of all cells, and changes in the medium are often necessary for different types of growth response from a single explant. A literature search is useful for selecting the appropriate medium.provide a useful guide on examining the effect of plant growth regu-lators, salt composition of the basal medium and a statistical analysis of the results. Likewise,can provide a guide for studying the effects of the MS inorganic salts on explant growth. If literature on the plant is not available, the development of a suitable medium is based on trial and error. The approach to developing the medium will depend on the purpose of the cell culture. Many of the media outlined in this manual can serve as useful starting points in developing a medium for a specific purpose, whether it is callus induction, somatic embryo-genesis, anther culture, or shoot proliferation.
