Knowledge about immunity to Middle East respiratory syndrome coronavirus (MERS-CoV) in dromedary camels is essential for infection control and vaccination. A longitudinal study of 11 dam-calf pairs showed that calves lose maternal MERS-CoV antibodies 5-6 months postparturition and are left susceptible to infection, indicating a short window of opportunity(More)
The effect of various fractions of black tea [(Camellia Sinensis) (L) O. Kuntze (Theaceae)] on the function of mammalian skeletomotor apparatus was studied. The theaflavin fraction (Tfs) produced a concentration- dependent facilitation of indirect twitch responses of the rat phrenic nerve diaphragm preparation and the facilitation was dependent on the(More)
The effect of substance P (sP) on mammalian skeletal myoneural transmission was studied employing innervated and denervated isolated rat diaphragm preparations. sP at a concentration of 3.7 nM facilitated the indirect twitch responses of the rat diaphragm and antagonised the paralytic effect of d-tubocurarine (d-Tc). sP failed to affect the direct twitch(More)
