abstract background: selectable marker gene (smg) systems are critical for generation of transgenic crops. transgenic crop production background: selectable marker gene (smg) systems are critical for generation of transgenic crops. transgenic crop production without using smg is not economically feasible. however, smgs are non-essential once an intact transgenic plant has been established. elim...

background depending on the cause, 40-90% of every deep dermis insult ends up in scar formation. several modalities have been suggested as a treatment but a high rate of recurrence is reported in most of those interventions. high dose radiotherapy has been shown to be effective in reducing the recurrence rate. this study tried to determine the effectiveness of low dose rate radiotherapy followi...

severe combined immunodeficiency (scid) represents a rare group of primary immunodeficiency disorders (pids), with known or unknown genetic alterations. here, we report a new interleukin 2 receptor, gamma chain (il-2rg) mutation in an iranian scid newborn.the patient was a 6-day old boy with a family history of pid. the child was screened using a molecular-based analysis for the assessment of t...

AIMS To determine important factors influencing recurrence after local excision of duct carcinoma in situ (DCIS) of the breast. MATERIALS AND METHODS The extent (size) in millimetres, classification (by cytonuclear grade (NHSBSP system), by extent of necrosis, and by the Van Nuys system), and excision margins of 115 cases of screen detected DCIS treated by local excision were measured. A prog...
