In this review, the vitamin C trials with military personnel and with other subjects living under conditions comparable to those of military recruits are analyzed to find out whether vitamin C supplementation affects respiratory infections. For this systematic review, we identified seven trials with military personnel, three trials with students in crowded lodgings, and two trials with marathon...

We explore the performance boundaries of sub1 GHz Wireless Local Area Networks (WLANs) and summarize the limitations of our proposed narrow-band WLAN system that uses carrier frequencies at 920 MHz with 1 MHz channel bandwidth. While there are several evaluation reports on WLAN testbeds available, no report is available that discusses the boundaries of narrow-band multiple-input multiple-output...

The first total synthesis of the potent antitumor agent fostriecin (CI-920) is described, confirming the relative and absolute stereochemistry assignments. Fostriecin is a unique phosphate monoester which exhibits weak topoisomerase II inhibition (IC(50) = 40 microM) and more potent and selective protein phosphatase 2A and 4 (PP2A and PP4) inhibition (IC(50) = 40-3 nM and 1.5 nM), resulting in ...

Among the vector-borne flaviviruses, West Nile virus (WNV), tick-borne encephalitis virus (TBEV) and Dengue virus (DENV) constitute the most frequently-observed pathogens with significant public health impact in endemic regions throughout the globe. This seroepidemiological study was undertaken to investigate human exposure to DENV, WNV and TBEV, as well as other flaviviruses via various serolo...

The electronic absorption spectra of oxidized and reduced spinach ferredoxins have been measured between 1200 and 600 nm at low temperature in D(2)O/ethylene glycol glasses. Relatively weak absorption bands are observed at 720, 820, and 920 nm in oxidized ferredoxin, and at 652, 820, and 920 nm in reduced ferredoxin. The spectral results show that the two Fe(III) centers in oxidized ferredoxin ...
