Two Creams, Three Sugars

Rheological Studies of Interferon Creams

The determination of flow curves and the apparent viscosity curves at 28°C of creams containing human leukocyte alpha interferon as active principle is presented in this paper. These creams are used for the treatment of papiloma virus and herpes simplex. It is demonstrated that their behaviour corresponds to a thixotropic fluid. The Herschel-Bulkley model parameters are presented and discussed ...

Ice-creams and wedge graphs

What is the minimum angle α > 0 such that given any set of α-directional antennas (that is, antennas each of which can communicate along a wedge of angle α), one can always assign a direction to each antenna such that the resulting communication graph is connected? Here two antennas are connected by an edge if and only if each lies in the wedge assigned to the other. This problem was recently p...

Barrier creams and their evaluation.

Barrier creams for skin breakdown

Debbie Flynn and Sally Williams examine how moisture and pressure can cause skin to break down, how barrier creams can help the skin to heal and a new barrier system. Nurses have a major role to play in assessing and preventing skin breakdown. It is essential to risk assess all patients to identify those most likely to be vulnerable. Incontinence poses particular risk factors as both urine and ...

A Tale of Two Sugars: Trehalose 6-Phosphate and Sucrose.

Trehalose 6-phosphate (Tre6P), the intermediate of trehalose biosynthesis, is an essential signal metabolite in plants, linking growth and development to carbon status. The Suc-Tre6P nexus model postulates that Tre6P is both a signal and negative feedback regulator of Suc levels, forming part of a mechanism to maintain Suc levels within an optimal range and functionally comparable to the insuli...
