Distribution of siderophore gene systems on a Vibrionaceae phylogeny: Database searches, phylogenetic analyses and evolutionary perspectives.

Siderophores are small molecules synthesized and secreted by bacteria and fungi to scavenge iron. Extracellular ferri-siderohores are recognized by cognate receptors on the cell surface for transport over membranes. Several siderophore systems from Vibrionaceae representatives are known and well understood, e.

[Terminology concerning intravenous ports].

Ports are more and more often applied with patients requiring the permanent intravenous access, not only in the cancer treatment. Very devices, as well as procedures associated with applying them are determined in the heterogeneous way. Therefore during the last conference "Intravenous Port--implantation, care, complications" an attempt to systematize the applied terminology was made.

Temporal order judgement for auditory and visual stimuli.

The ability to perceive temporal order for pairs of auditory and visual stimuli was investigated in 12 volunteers. They were asked to make judgements about the order of presented stimuli by pressing two response buttons in a certain order. The performance on auditory and visual tests was studied in relation to the Inter-Stimulus-Interval (ISI), which varied from 5 to 500 ms.
