Abstract:
Over the last decade, finding bacterial strains with ability to accumulate high concentrations of lipids has gained increasing interest, since these lipids may be used in different industries. Here we describe two methods for evaluation of lipid accumulation in cyanobacteria, following by our personal reflection on issues surrounding the use of these methods. First, we present the Bligh and Dyer protocol as a traditional extraction method using organic solvents for quantitative determination of lipids and next Nile red, a selective fluorescent stain, that has been used as a rapid approach for both qualitative and quantitative measurement of lipids.

Guidelines for Nursing Documentation II
Timely documentation is crucial to ensure continuity of care for patients. Any delays in recording or reporting medical information can result in medical errors and even adverse patient outcomes. From medication administration to diagnostic test results, every detail must be accurately and promptly documented to provide the best possible care for patients.
