“…Based on a change in the color of colonies, the results suggested that some microorganisms on the plates accumulated azobenzene (Table 1). The ability of azobenzene to effect its distribution in the agar medium may be related with its metastability (Haring, 1946;Sharp, 1946). The ability of azobenzene to effect its distribution in the agar medium may be related with its metastability (Haring, 1946;Sharp, 1946).…”

Although approximately 10% of all newborn infants receive some form of assistance after birth, only 1% of neonates require more advanced measures of life support. Because such situations cannot always be anticipated, paediatricians and neonatologists are frequently unavailable and resuscitation is delegated to the anaesthesiologist. The International Liaison Committee on Resuscitation, the European Resuscitation Council and the American Heart Association have recently updated the guidelines on neonatal resuscitation. The revised guidelines propose a simplified resuscitation algorithm that highlights the central role of respiratory support and promotes an increasing heart rate as the best indicator for effective ventilation. The most striking change in the new guidelines is the recommendation to start resuscitation in term infants with room air rather than 100% oxygen. Continuous pulse oximetry is recommended to monitor both heart rate and an appropriate increase in preductal oxygen saturation. Supplemental oxygen should only be used if, despite effective ventilation, the heart rate does not increase above 100 beats min(-1), or if oxygenation as indicated by pulse oximetry, remains unacceptably low. This review will focus on foetal physiology and pathophysiological aspects of neonatal adaptation and, thus, attempt to provide a solid basis for understanding the new resuscitation guidelines.

“…The use of 4-(p-phenylazophenyl) semicarbazide gave highly coloured, easily isolated and beautifully crystalline derivatives in excellent yield. Since these 4-(p-phenylazophenyl) semicarbazones contain the carcinogenic 23 and insecticidal 249 25 azobenzene fragment and are structurally related to germicidal 25 and bacteriostatic azo-dyes they will be the subject of a separate fungicidal and antibacterial evaluation.…”

The preparation and characterisation of the 4-(p-phenylazophenyl)semicarbazones of pyridine-2,3 and 4-aldehyde, 2,3 and 4-acetylpyridine, 6-methylpyridine-2-aldehyde and pyridine-2,6-dialdehyde are described. These semicarbazones proved most useful for the isolation and characterisation of carbonylic pyridines. The preparation of the semicarbazones was carried out in dry ethanol and crystalline coloured products were obtained in good yield.

“…Interestingly, a review was reported to compile some examples of proper azobenzene dyes as antimicrobials. And azobenzene dusts , were reported to be particularly effective against red spider mite and the Mexican bean beetle in the 1940s. Therefore, we deemed that azo-incorporating, as an optimization strategy in increasing activities, would contribute to diversified development of pesticides.…”

Azo-incorporating Increases Inhibitory Activity of Succinate Dehydrogenase

Diversity of pesticide discovery provided a solution to resistance. Here, we presented a strategy of azo-incorporating to promote the diverse developments of fungicide. A series of novel fungicides were synthesized by incorporating azobenzene derivatives into fluxapyroxad. Much better in vitro fungicidal activity increases for compound 9d were observed compared to the positive control, fluxapyroxad against Botrytis cinerea and Rhizoctonia solani. Compound 9d (IC50 = 0.03 μM) also had a great enzyme-inhibiting activity increase toward succinate dehydrogenase in comparison with fluxapyroxad (IC50 = 4.40 μM). A comparatively equivalent biological activity was observed between compounds 8a and 9d. SEM analysis helped us to observe clearly the morphology of the fungi before and after active ingredient delivery. Our results of molecular docking analysis, fluorescence quenching analysis, and enzymatic assays demonstrated that compound 8a and 9d act on SDH. An increase in inhibitory activity could be occurring after incorporation of azobenzene, which provided a new strategy for molecular design in pesticide discovery.
