LAM2: An Unusual Laminaran Structure for a Novel Plant Elicitor Candidate.

Laminarans are of interest because they have been shown to induce various immune responses in animals and plants. These β-D-glucans differ from each other by their branching rate, which is possibly responsible for their biological activities. In the present study, we characterized a laminaran fraction extracted from and named LAM2 using sugar composition and structural analyses (NMR).

Working-memory capacity and reading comprehension in young and older adults.

This study investigates the role of working-memory capacity in reading comprehension in young and older subjects. A task yielding separate measures for processing and storage components was used to assess working-memory capacity. A French version of the Nelson-Denny test was administered as a measure of abilities that underlie reading comprehension.

[Comparative study of the results of measurements of beta2-microglobulin and carcino-embryonic antigen in human digestive tract carcinomas (author's transl)].

The studies of the levels of the CEA and of the beta2m were both performed on 52 patients. The authors pointed out the interest of measurement of these 2 markers and above all the interest of their complementary before any therapy and during treatment by surgery or radiotherapy whether associated or not.

[Characterization and quantification by impulse analysis of sugar regulation disorders in man].

Proposed model offers three transfer functions answering to a second order hypothesis and allowing to study separately blood sugar evolution and insulin release or synthesis functions by cell B. The model separates subjects in several classes (normals, chemical diabetes and patent insulin-dependent or independent diabetes) and quantifies treatment efficiency by its effects on blood sugar regulation.
