Transcriptomic analysis reveals responses to Cycloastragenol in Arabidopsis thaliana.

Cycloastragenol (CAG), a molecule isolated from 'Astragalus membranaceus', stimulates the telomerase activity and cell proliferation significantly. It has been proven that CAG has the ability to prevent some diseases in humans. In this study, we aimed to figure out the CAG effects on the different signaling mechanisms in plants and to broadly analyze the genome-wide transcriptional responses in order to demonstrate CAG as a new key molecule that can potentially help plants to overcome different environmental stresses.

[Corneal graft rejection: donor and receiver implication].

Purpose: The purpose of our study was to evaluate the relationship between corneal graft failure and different factors related to both donors and recipients.

Patients: and methods: We conducted a retrospective control study on cases treated from January 1998 to December 2000. All records for donors to the eye bank unit of the Sfax forensic medicine department and all records for penetrating keratoplasty operations done in the Sfax Ophthalmology department were reviewed.

[Contusive retinal detachment: a retrospective review of 48 patients].

Purpose: Analysis of the epidemiological, clinical and therapeutic characteristics of retinal detachment after ocular blunt trauma.

Material And Methods: We retrospectively reviewed 48 patients with isolated retinal detachment after ocular blunt trauma, studying their epidemiological characteristics (age, sex and trauma circumstances), their clinic details and the surgical techniques used.

Results: The average age of our patients was 39.
