Phenolic compounds of Phellinus spp. with antibacterial and antiviral activities.

Phellinus Quél is one of the largest genera of Hymenochaetaceae; it comprises about 220 species widely distributed on Earth. Most Phellinus species are lignicolous mushrooms that accumulate bioactive compounds. This research studied the phenolic composition of Phellinus spp.

Proteomic profiling of integral membrane proteins associated to pathogenicity in Vibrio parahaemolyticus strains.

Vibrio parahaemolyticus has been recognized as the causal agent of early mortality syndrome and is currently considered an emerging shrimp disease causing losses of millions in the aquaculture industry. Integral membrane proteins are widely recognized as pathogenicity factors involved in essential mechanisms for V. parahaemolyticus infection, which makes them attractive as therapeutic targets.

[HIV/AIDS: expression of nursing students imaginary through photography].

Potential of medicinal plants as antimicrobial and antioxidant agents in food industry: a hypothesis.

Many food preservation strategies can be used for the control of microbial spoilage and oxidation; however, these quality problems are not yet controlled adequately. Although synthetic antimicrobial and antioxidant agents are approved in many countries, the use of natural safe and effective preservatives is a demand of food consumers and producers. This paper proposes medicinal plants, traditionally used to treat health disorders and prevent diseases, as a source of bioactive compounds having food additive properties.
