NMR spectrometers as "magnetic tongues": prediction of sensory descriptors in canned tomatoes.

The perception of odor and flavor of food is a complicated physiological and psychological process that cannot be explained by simple models. Quantitative descriptive analysis is a technique used to describe sensory features. Nevertheless, the availability of a number of instrumental techniques has opened up the possibility to calibrate the sensory perception.

[Sodium gold thiosulfate therapy: an open, viewed, multicenter trial in rheumatoid arthritis patients followed for two years].

Objective: To evaluate if parenteral gold-therapy with Sodium gold thiosulfate is effective and safe for the treatment of rheumatoid arthritis we began an open, multicenter trial.

Methods: 126 rheumatoid arthritis patients were treated with Sodium gold thiosulfate for two years. Efficacy, quality of life, progression of joint damage, inflammatory parameters and side effects were evaluated.

Environmental and social factors in rheumatoid factor epidemiology.

The effect of social and environmental conditions on the epidemiology of Rheumatoid Factor (RF) in healthy population was studied. For this purpose 2 sample of 828 subject was studied using 5 tests for RF. Our sample included: 419 randomized subjects from a quarter at the outskirts of Bologna (high rate immigration, non homogeneous habits and health background; 409 randomized subjects from one rural small town on the Romagna's hills (no immigration, no change in residence or profession for generations, uniform, habits and health background).

[Rheumatoid serology: insufficient using a single test].

The rheumatoid factor research restricted to only a test finds evident limitation not only in clinical field, but also on epidemiological investigations. The problem may find a solution by contemporary employment of a tests pool both in epidemiology and in the different physiopathological conditions present in rheumatology. Such kind of proposal has been verified on rheumatic diseases (rheumatoid arthritis classic or probable, polyarthritic syndrome, polyarthritis, spondylitis, psoriatic arthritis) and not rheumatic ones and in control group population (2901 subjects controlled).
