CA-MRSA colonization with PVL-positive strains was associated with a significant risk of soft-tissue infection, suggesting that CA-MRSA may be more virulent than MSSA. Previous antibiotic use may play a role in CA-MRSA colonization.

Graphene has attracted extensive research interest due to its strictly 2-dimensional (2D) structure, which results in its unique electronic, thermal, mechanical, and chemical properties and potential technical applications. These remarkable characteristics of graphene, along with the inherent benefits of a carbon material, make it a promising candidate for application in electrochemical energy devices. This article reviews the methods of graphene preparation, introduces the unique electrochemical behavior of graphene, and summarizes the recent research and development on graphene-based fuel cells, supercapacitors and lithium ion batteries. In addition, promising areas are identified for the future development of graphene-based materials in electrochemical energy conversion and storage systems.

HE MAGNITUDE OF INVASIVEmethicillin-resistant Staphylococcus aureus (MRSA) infections as well as the emergence of community-onset MRSA infections in the United States has been well documented. [1][2][3][4] Commonly due to the pulsedfield type USA300 strain of MRSA, outbreaks of skin and soft tissue infections (SSTIs) have been observed in prisoners, athletes, and other risk groups. 5,6 In parallel with the emergence of community-onset MRSA infections in the US civilian population, SSTIs have become a significant public health issue for the US military. During military training, approximately 4% to 6% of all individuals may experience an SSTI. 7,8 Furthermore, S aureus has been isolated from 91% of such cases, with MRSA accounting for 70% of S aureus isolates. MRSA also has been shown to be a common cause of S aureus bacteremia and other infections in population-based studies from the United States, particularly health care-associated infections.
