- Unlike other fields of computing and communications, low-power wireless networking is plagued by one major issue: the absence of a well-defined, agreed-upon yardstick to compare the performance of systems, namely, a benchmark. We argue that this situation may eventually represent a hampering factor for a technology expected to be key in the Internet of Things (IoT) and Cyber-physical Systems (CPS). This paper describes a recent initiative to remedy this situation, seeking to enlarge the participation from the community.

- Treatment options for gonorrhoea are scarce. Drug repurposing of bioactive molecules approved for other conditions might therefore be of value. We developed a method for wide-scale, systematic drug repurposing screen to identify molecules with activity against Neisseria gonorrhoeae and screened the Prestwick Chemical Library (1200 FDA-approved drugs). As a proof-of-concept, we further examined one promising and interesting screening hit (auranofin; antirheumatic agent). Three WHO gonococcal reference strains (WHO F, O, P) were used for the Library screening. The strains were grown in presence of a fixed concentration of the library drugs in 384-well plates for 12 hours and the remaining bacterial respiration, to reflect growth, was then quantitatively measured using optical density (OD) 450 nm and a resazurin assay. The activity of auranofin was further examined using in vitro susceptibility testing (minimum inhibitory concentration (MIC) and minimum bactericidal concentration (MBC)) against genetically diverse antimicrobial-resistant N. gonorrhoeae strains and time-kill assays. Sixty-eight molecules significantly inhibited bacterial growth of WHO F, O and, P. Auranofin showed potent in vitro bactericidal activity (in MIC-, MBC-, and time-kill assays) against four WHO reference strains. No cross resistance between auranofin and any antimicrobial currently or previously used for gonorrhoea treatment was found when examining 51 selected antimicrobial-resistant gonococcal strains. In conclusion, this is the first wide-scale systematic screening effort for repurposing drugs for future treatment of gonorrhoea. Additional studies examining mechanism(s) of action, resistance development, in vivo anti-gonococcal activity, and pharmacokinetics/pharmacodynamics for gonococcal infections of auranofin and several other significant screening hits would be valuable.

- A greater adherence to the traditional Mediterranean (MED) diet is associated with a reduced risk of developing chronic diseases. This dietary pattern is based on higher consumption of plant products that are rich in flavonoids. We compared the total flavonoid dietary intakes, their food sources and various lifestyle factors between MED and non-MED countries participating in the EPIC study. Flavonoid intakes and their food sources for 35 628 subjects, aged 35-74 years and recruited between 1992 and 2000, in twenty-six study centres were estimated using standardised 24 h dietary recall software (EPIC-Soft (R)). An ad hoc food composition database on flavonoids was compiled using analytical data from the United States Department of Agriculture and Phenol-Explorer databases. Moreover, it was expanded to include using recipes, estimations of missing values and flavonoid retention factors. No significant differences in total flavonoid mean intake between non-MED countries (373.7 mg/d) and MED countries (370.2 mg/d) were observed. In the non-MED region, the main contributors were proanthocyanidins (48.2 %) and flavan-3-ol monomers (24.9 %) and the principal food sources were tea (25.7 %) and fruits (32.8 %). In the MED region, proanthocyanidins (59.0 %) were by far the most abundant contributor and fruits (55.1 %), wines (16.7 %) and tea (6.8 %) were the main food sources. The present study shows similar results for total dietary flavonoid intakes, but significant differences in flavonoid class intakes, food sources and some characteristics between MED and non-MED countries. These differences should be considered in studies about the relationships between flavonoid intake and chronic diseases.
