A recently published method for Factor X (FX) assay (1) utilizing Russel's Viper Venom (RVV) and a chromogenic substrate has been further investigated by testing a large number of parameters. This method has been considered as a suitable method for monitoring coumarol treatment (Bergström et al).The conditions for the activation of FX by purified preparations of the RVV have been studied as well as the conditions for FXa determination with a new chromogenic substrate Bz-Ile-Glu(γ-piperidyl)-Gly-Arg-pNA (S-2337). Both purified factors and normal plasma have been used. The effect of plasma inhibitors as well as the selectivity of the method has been studied.The reproducibility and stability of the different reagents and standards have been studied and found to be good.The amount of FXa activity obtained from normal human plasma has been titrated with FXa inhibitors of known purity.1) Aurell L. et al, Thromb.

Biofilm Matrix

To study the composition of a biofilm a previous extraction method is required to separate cells from the matrix. There are several methods reported in the literature; however they are not efficient or promote leakage of intracellular material. In this work several extraction methods were assayed in mixed culture and pure culture biofilms and their efficiency was evaluated by the amount of organic carbon, proteins and intracellular material extracted. The results showed that the extraction with glutaraldehyde 3% (w/v) was the most suitable method, extracting great amounts of organic carbon without promoting cell lysis or permeabilization. Glutaraldehyde is a bifunctional reagent that binds to cell walls avoiding their permeabilization and the biofilm matrix is solubilized in the solution.

It is over a decade since a study of legends of St. Peter in medieval Latin hymns appeared (Traditio 10 [1954] 275–322), followed not only by a number of other monographs but also by a more comprehensive investigation of the history of medieval Latin hymnody, now completed. The questions raised in that article in Traditio have still their significance and the search for a suitable method, or methods, in hymnology is not yet ended. Successive investigations in this field have gradually revealed some of the possibilities in hymnological research; we have noted that the study of legends and narrative sources reflected in hymn-texts may result in concrete discoveries which aid the analytic investigation of medieval hymns. Through them we often come to learn something about the contemporary intellectual trends and the ideas that were lingering in the minds of the people of those times. We also discover echoes of popular beliefs and cults by analyzing certain elements of the hymns. Further investigations in the terminology and style of the hymns can lead us to medieval exegetic and homiletic literature, to patristic sources and the like, which, too, left their imprint on Latin hymnody.

The rate of water filtration by bivalves has long excited interest, but it has in practice proved difficult to measure in conditions where the animal is relatively free from constraint. Its estimation is important from a number of aspects: feeding studies; as an indicator of the animal's reaction to its environment; and for predicting the flow of water required for the culture of economically important species. The work reported in this paper started as part of the general programme on shellfish culture in progress at this laboratory. During the development of a suitable method for studying the water requirements it became clear that one factor, water current, had a more important influence than has been generally recognized.

We have compared an in-house horizontal thin layer chromatography (TLC) method with a commercial TLC screening kit (Toxi-Lab) to find the most suitable method for screening urine for opioid drugs. The in-house TLC procedure is cheaper and more efficient than the commercial TLC method and is ideal as a confirmatory method when used in conjunction with other established laboratory methods. The in-house TLC method is useful for one-off requests and is able to differentiate between small quantities (0·1–0·5 mg/L) of the different, commonly abused opioids and their metabolites, which means that it is well suited for use at a local Drug Addiction Unit as a routine screening service.
