Investigation of mitochondrial protein expression profiles of Yarrowia lipolytica in response to citric acid production.

Nitrogen-limiting condition is essential for citric acid production by Yarrowia lipolytica. Mitochondrial protein expression profiles of Y. lipolytica IMUFRJ 50,682 cells cultivated in biomass proliferation medium (YPG medium, yeast extract, peptone and glycerol) and citric acid production medium (CA medium) were analyzed to identify differences in expressed proteins in response to medium composition.

Protective factors in mature human milk: a look into the proteome and peptidome of adolescent mothers' breast milk.

The characterisation of proteome and peptidome of adolescent mothers' breast milk brings important information to both mother's and infant's health; however, it has not been investigated. Bioactive peptides derived from milk proteins have numerous functions. The bioactivity of breast milk peptides includes anti-inflammatory and antimicrobial activities and regulation of gastrointestinal function.

Comparative salivary proteome of hepatitis B- and C-infected patients.

Hepatitis B and C virus (HBV and HCV) infections are an important cause of cirrhosis and hepatocellular carcinoma. The natural history has a prominent latent phase, and infected patients may remain undiagnosed; this situation may lead to the continuing spread of these infections in the community. Compelling reasons exist for using saliva as a diagnostic fluid because it meets the demands of being an inexpensive, noninvasive and easy-to-use diagnostic method.
