Baker's asthma is a serious airway disease triggered by wheat protein CM3 α-amylase/trypsin inhibitor. The purpose of the present study was to investigate the impact of genotype and crop year on allergen CM3 α-amylase/trypsin inhibitor associated with baker's asthma. A historical series of Tunisian durum wheat (100 accessions), derived from three crop years, was used to compare the amount of CM3 from landraces to advanced cultivars.

The aim of this study was to compare immunogenic and toxic gluten peptides related to celiac disease (CD). 100 accessions of genotypes selected during the 20th century in Tunisia were in vitro digested and then analyzed by UPLC/ESI-MS technique using an isotopically labeled internal standard. The first MANOVA confirmed a high variability in the content of immunogenic and toxic peptides reflecting high genetic diversity in the germplasm released during the past century in Tunisia, consistently with PCA and clustering analysis results.

In water-limited areas of Tunisia, more than 30% of subsurface water used for irrigation is saline water, leading to a long-term salinization and degradation processes. To prevent the problems and to minimize the negative impact of using saline water, selection of proper germplasm as well as integrated soil and water management are essential. Understanding the diversity for salt tolerance in barley (Hordeum vulgare L.

A new cryoprobe for cyclocryocoagulation was investigated in a clinical trial. A group of 15 patients was treated with one step coagulation at 120 degrees C; a control group of 15 patients was treated with a CO2-cooled cryoprobe using circular coagulation in the usual manner. Statistical evaluation showed a significant drop in IOP in both groups after cryocoagulation.

In a retrospective study 37 penetrating keratoplasties performed on 33 eyes of 29 patients under age 12 were evaluated. One year postoperatively, 19 of 35 grafts were clear and 16 of 35 had failed. In the group aged under 3, most of whom had congenital anomalies, 4 of 14 had clear grafts and 10 of 14 failed grafts after one year.
