Vibrational spectroscopies for the analysis of cutaneous permeation: experimental limiting factors identified in the case of caffeine penetration

13-Nov-2012 | Sana Tfaili, Cyril Gobinet, Gwendal Josse, Jean-François Angiboust, Arlette Baillet, Michel Manfait, Olivier Piot, Analytical and Bioanalytical Chemistry, 2012

Caffeine is utilised as a reference for permeation studies in dermatology and cosmetology. The present work aimed to monitor the permeation of a caffeine solution through the skin. For this purpose, Raman and infrared studies were performed. Raman microspectroscopy permitted a dynamic follow-up ...

In situ electrochemical evaluation of anticancer drug temozolomide and its metabolites–DNA interaction

13-Nov-2012 | Ilanna C. Lopes, S. Carlos B. Oliveira, Ana Maria Oliveira-Brett, Analytical and Bioanalytical Chemistry, 2012

Temozolomide (TMZ) is an antineoplastic alkylating agent with activity against serious and aggressive types of brain tumours. It has been postulated that TMZ exerts its antitumor activity via its spontaneous degradation at physiological pH. The in vitro evaluation of the interaction of TMZ and ...

Comparison of different extraction methods for simultaneous determination of B complex vitamins in nutritional yeast using LC/MS-TOF and stable isotope dilution assay

13-Nov-2012 | Kristel Hälvin, Toomas Paalme, Ildar Nisamedtinov, Analytical and Bioanalytical Chemistry, 2012

The application of LC/MS-TOF method combined with stable isotope dilution assay was studied for determination of thiamine, riboflavin, nicotinamide, nicotinic acid, pantothenic acid, pyridoxal, and pyridoxine in food. Nutritional yeast powder was used as a model food matrix. Acid extraction was ...

Comparative studies of thiol-sensitive fluorogenic probes for HAT assays

09-Nov-2012 | Tielong Gao, Chao Yang, Yujun George Zheng, Analytical and Bioanalytical Chemistry, 2012

Histone acetyltransferases (HATs) catalyze the acetylation of specific lysine residues in histone and nonhistone proteins. Recent studies showed that acetylation is widely distributed among cellular proteins, suggestive of diverse functions of HATs in cellular pathways. Nevertheless, currently ...
