is only a tenth as virulent as ordinary flu, and only one hundredth as virulent as the Spanish flu at the end of World War 1.” In The Guardian (15 January), Simon Jenkins showed a similar blend of raw assertion with lack of any comprehension of the complexities and uncertainties involved in fathoming viral evolution. “Sir Liam Donaldson bandied about any figure that came into his head, settling...

Possible Relaxant Effects of Thymoquinone on Guinea Pig Tracheal Chain

In the previous studies the relaxant, anti-cholinergic (functional antagonism) and anti-histaminic effects of Nigella sativa have been demonstrated on guinea pig tracheal chains. To elucidate the main substance responsible for the relaxant effect of this plant, the effect of thymoquinone, one of the main constituent of Nigella sativa was examined in this study. The bronchodilatory effects of th...

Migraine treatment: a chain of adverse effects

This clinical vignette presents a 14 years old female, with a past medical history relevant only for migraine with typical aura of less than monthly frequency, complaining of a severe unilateral headache with rising intensity for the previous 4 h, associated with nausea, vomiting, photophobia and phonophobia. This episode of migraine with aura in a patient with recurrent migraine was complicate...

Effects of chain length on oligopeptide hydrogelation.

The co-assembly of mutually complementary, but self-repulsive oligopeptide pairs into viscoelastic hydrogels has been studied. Oligopeptides of 6, 10, and 14 amino acid residues were used to investigate the effects of peptide chain length on the structural and mechanical properties of the resulting hydrogels. Biophysical characterizations, including dynamic rheometry, small-angle X-ray scatteri...
