The molecular weights of plasma proteins from healthy subjects and from patients with well-or badly-controlled diabetes mellitus have been determined by use of a matrix-assisted laser desorption ionization method, representing a highly accurate technique for the determination of the molecular weight of large biomolecules. Using this approach, different molecular weights of human serum albumin have been found for healthy (66,572-66,694 dalton) and diabetic (66,785-68,959 dalton) subjects. Such differences can be rationalized as being due to the different number of glucose molecules condensed on the protein and/or their further oxidation products; in the case of our diabetic patients this number is in the range of 1.4-14.8. The data show the high validity and specificity of the technique, which allows us to evaluate, without any protein degradation procedure, the number of glucose molecules condensed on a specific protein and ascertain the relationship of this number to the physiopathogenetic conditions of the subjects studied.

The article discusses a questionnaire evaluating the quality of life outcomes in rhinoplasty patients and mentions the linguistic validation and translation of the questionnaire in Italian language. Topics include the use of FACE-Q scales to determine patient's satisfaction in nose cosmetic surgery, and the need to follow thorough linguistic validation process for better patient-reported outcome.
