purpose : recession is the main surgical procedure in correction of eye deviation in duane’s syndrome. we evaluate the efficacy of botulinum toxin injection in the treatment of this type of strabismus instead of surgery or before it. methods : three patients with duane’s syndrome type i and one patient with type ii were selected at poostchi eye clinic from patients who diagnosed primarily and h...

The effect of O(2) and CO(2) on expression of toxic shock syndrome toxin 1 (TSST-1) by Staphylococcus aureus was investigated under controlled growth conditions with continuous-culture techniques. To stimulate TSST-1 production, air and anaerobic gas were premixed before delivery to the culture vessel. At a growth rate-or mass doubling time (t(d))-of 3 h, production of specific TSST-1 (expresse...

A fundamental problem of plant science is to understand the biochemical basis of plant/pathogen interactions. The foliar disease tan spot of wheat (Triticum aestivum), caused by Pyrenophora tritici-repentis, involves Ptr ToxA, a proteinaceous host-selective toxin that causes host cell death. The fungal gene ToxA encodes a 17.2-kD pre-pro-protein that is processed to produce the mature 13.2-kD t...

Fluorescent derivatives of gangliosides were prepared by oxidizing the sialyl residues to aldehydes and reacting them with fluorescent hydrazides. When rhodaminyl gangliosides were incubated with lymphocytes, the cells incorporated them in a time- and temperature-dependent manner. Initially, the gangliosides were evenly distributed on the cell surface but were redistributed into patches and cap...

Expression of bacterial type II toxin-antitoxin (TA) systems is regulated at the transcriptional level through direct binding of the antitoxin to pseudo-palindromic sequences on operator DNA. In this context, the toxin functions as a co-repressor by stimulating DNA binding through direct interaction with the antitoxin. Here, we determine crystal structures of the complete 90 kDa heterooctameric...
