Tip of the Day Angles subtended by an arc or a chord of a circle, at distinct points on its circumference, in the same segment, are equal. Also, the measure of this angle is half the measure of the angle subtended by the chord or arc at the centre. Last year's Question of the day (29-Oct-10) In 1930, Cecil George Paine, a pathologist at the Royal Infirmary in Sheffield, attempted to use penicillin to treat sycosis barbae–eruptions in beard follicles, but was unsuccessful, probably because the drug did not penetrate the skin deeply enough. Moving on to ophthalmia neonatorum; a gonococcal infection in infants, he achieved the first recorded cure with penicillin, on November 25, 1930. He then cured four additional patients (one adult and three infants) of eye infections, failing to cure a fifth.
In 1939, Australian scientist Howard Florey (later Baron Florey) and a team of researchers (Ernst Boris Chain, A. D. Gardner, Norman Heatley, M. Jennings, J. Orr-Ewing and G. Sanders) at the Sir William Dunn School of Pathology, University of Oxford made significant progress in showing the in vivo bactericidal action of penicillin.
How many patients did Paine not fail to cure using penicillin?
