1977a). Neither of these assertions, however, is based on -definite evidence. The relevance, for example, of the observation (Hayreh, 1976, 1977b) that fluorescein can diffuse from the cistema magna to the vitreous cavity via the -subarachnoid space, optic nerve, and optic disc is unclear. The prelaminar venular congestion mentioned by Mr Primrose was observed to be a late event during the deve...

As a general rule normal saline is employed which has been made up by the hospital dispenser and stored in glass-stoppered hottles. As these are not sterile on the outside. the usual procedure is for a nurse who has not scrubbed up, to pour the saline into a sterilized undine or container. In doing this there is a. very good chance that she will contaminate the neck of the bottle with her finge...

We consider an enhancement in the violation of lepton flavour universality in light meson decays arising from modified Wlν couplings in the standard model minimally extended by sterile neutrinos. Due to the presence of additional mixings between the active neutrinos and the new sterile states, the deviation from unitarity of the leptonic mixing matrix intervening in charged currents might lead ...

Reduction of mosquito populations will, at least, reduce substantially the transmission of malaria disease. One potential method of achieving this reduction is the environmentally-friendly population control method known as the Sterile Insect Control (SIT) method. The SIT method has so far not been widely used against insect disease vectors, such as mosquitoes, because of various practical diff...

BACKGROUND AND AIMS Why are sterile anthers and carpels retained in some flowering plants, given their likely costs? To address this question, a cryptically dioecious species, Petasites tricholobus, in which male and female plants each have two floret types that appear pistillate and hermaphroditic, was studied. The aim was to understand the function of sterile hermaphroditic florets in females...

The protozoan parasite Giardia lamblia synthesizes a diverse and surprisingly abundant array of sterile transcripts unable to code for proteins. Random sampling of cDNAs from two evolutionarily divergent Giardia strains indicates that approximately 20% of cDNAs in the libraries represent polyadenylated sterile transcripts. RNase protection analysis and northern blot hybridization of three steri...
