Combined effects of ionic strength and enzymatic pre-treatment in thermal gelation of peanut proteins extracts.

Peanut proteins are mostly composed of arachins and conarachins, globular proteins that can form gels under thermal denaturation or enzymatic treatment. We explored here how ionic strength (0.5 M or 0.

Mowing strategies for controlling Cirsium arvense in a permanent pasture in New Zealand compared using a matrix model.

Defoliation has frequently been proposed as a means of controlling Cirsium arvense (L.) Scop. (Californian thistle, Canada thistle, creeping thistle, perennial thistle), an economically damaging pastoral weed in temperate regions of the world, but its optimization has remained obscure.

How can screening for malnutrition among hospitalized patients be improved? An automatic e-mail alert system when admitting previously malnourished patients.

Background & Aims: Screening for malnutrition is not often done in the management of hospitalized patients. An original computer tool was developed at the Dunkerque hospital to detect readmissions of patients with malnutrition during a previous stay and generate e-mail alerts to the nutrition department. The aim of the study was to describe and evaluate this tool and the activity of the nutrition department in connection with the alerts sent.

Mathematical determination of cell population doubling times for multiple cell lines.

Cell cycle times are vital parameters in cancer research, and short cell cycle times are often related to poor survival of cancer patients. A method for experimental estimation of cell cycle times, or doubling times of cultured cancer cell populations, based on addition of paclitaxel (an inhibitor of cell division) has been proposed in literature. We use a mathematical model to investigate relationships between essential parameters of the cell division cycle following inhibition of cell division.

Analysis of radiation-induced changes to human melanoma cultures using a mathematical model.

Objectives: Tumour cells respond to ionizing radiation by cycle arrest, cell death or repair and possible regrowth. We have developed a dynamic mathematical model of the cell cycle to incorporate transition probabilities for entry into DNA replication and mitosis. In this study, we used the model to analyse effects of radiation on cultures of five human melanoma cell lines.
