A unique photochemical flow reactor featuring quartz tubing, an aluminum mirror and temperature control has been developed for the photo-induced electron-transfer deoxygenation reaction to produce 2'-deoxy and 2',3'-dideoxynucleosides. The continuous flow format significantly increased the efficiency and selectivity of the reaction.

Platypnoea-orthodeoxia is an infrequent syndrome that is usually associated with positional intracardiac right-to-left shunting. The authors report the case of a patient who presented with deteriorating severe dyspnoea and deoxygenation in the upright position that was partially relieved by recumbent repositioning. Dynamic echocardiography provided insight into the underlying anatomical and pat...

The magnitude and timing of oxygenation responses in highly active leg muscle, less active arm muscle, and cerebral tissue, have not been studied with simultaneous alveolar gas exchange measurement during incremental treadmill exercise. Nor is it known, if blood O(2) carrying capacity affects the tissue-specific oxygenation responses. Thus, we investigated alveolar gas exchange and tissue (m. v...

The modification of fatty substrates using heterogeneous catalysts have extensive industrial application and has an emphatic position in a sustainable context. Herein ruthenium, nickel, cobalt copper-doped supported on hypercrosslinked polystyrene (HPS) were prepared by wet impregnation, characterized applied the canola acid methyl esters (FAME). characterization showed dispersive effect doping...

The tropical Atlantic upper-ocean circulation experiences multiannual to decadal changes associated with different climate modes and is simultaneously adjusting warming. most energetic current in the Equatorial Undercurrent (EUC), which flows eastwards along Equator. On basis of long-term moored observations, we show that EUC strengthened by more than 20% from 2008 2018. intensification increas...

The environmental impact of traditional fuels and related greenhouse gas emissions (GHGE) has promoted policies driven towards renewable fuels. This review deals with green diesel, a biofuel obtained by catalytic deoxygenation edible non-edible biomasses. Green biodiesel, petrodiesel are compared, diesel being the best option in terms physical–chemical properties reduction GHGE. process types c...
