Peacock and his collaborators (12-15, 19) showed that injection of 3,4-benzpyrene into various animals caused a phenolic derivative to appear in the excreta. Further investigation by the present authors led to the recognition of 8-benzpyrenol in the feces of benzpyrene-injected mice and rats, associated with 3,4benzpyrene-5,8-quinone (2, 3). experiment (i. e., until the feces were free from chl...

The inaugural conference on Advances in Microfluidics and Nanofluidics was held at the Hong Kong University of Science and Technology on 5-7 January 2009 and brought together leading researchers from across a wide variety of disciplines from North America, Europe, Asia, and Oceania. This Special Topic section forms the second of the two issues dedicated to original contributions covering both f...

Public transit systems are ideal for studying the urban microbiome and interindividual community transfer. In this study, we used 16S amplicon and shotgun metagenomic sequencing to profile microbial communities on multiple transit surfaces across train lines and stations in the Boston metropolitan transit system. The greatest determinant of microbial community structure was the transit surface ...

Natural convection is a basic process which is important in a wide variety of practical applications [1,2]. In essence, a heated fluid expands and rises from buoyancy due to decreased density. Numerous papers have been written on natural or mixed convection in vertical ducts heated on the side. The effects of added viscous dissipation heat have been considered [3–8]. The fluid motions in all pr...

Large-scale genome sequencing has identified millions of protein-coding genes whose function is unknown. Many of these proteins are similar to characterized proteins from other organisms, but much of this information is missing from annotation databases and is hidden in the scientific literature. To make this information accessible, PaperBLAST uses EuropePMC to search the full text of scientifi...

In our previous papers, wereported the structure and stereochemistry of thiomarinol A (previously referred to as thiomarinol)1'2*, produced by a marine bacterium, Alteromonas rava sp. nov. SANK733903), which has antimicrobial activity against Gram-positive and Gramnegative bacteria. Thiomarinol A (TMA) is a hybrid antibiotic composed of a pseudomonic acid analogue and holothin. In this paper we...

The Comments and Addenda section is for short communications which are not of such urgency as to justify publication in Physical Review Letters and are not appropriate for regular Articles. It includes only the following types of communications: (I) comments on papers previously published in The Physical Review or Physical Review Letters; (2) addenda to papers previously puMished in The Physica...
