The root-to-root travel of the beneficial bacterium Azospirillum brasilense on wheat and soybean roots in agar, sand, and light-textured soil was monitored. We used a motile wild-type (Mot) strain and a motility-deficient (Mot) strain which was derived from the wild-type strain. The colonization levels of inoculated roots were similar for the two strains. Mot cells moved from inoculated roots (...

Introduction: Posterior segment retained Intraocular foreign body (IOFB) management is challenging. Facility of pars plana vitrectomy (PPV) and availability well trained vitreo retina surgeons are the basic need to accomplish this work. Encircling band provide permanent 360° support close anterior retinal break prevent traction on retina. The objective study analyse clinical characteristics pre...

Aims—To study the eVects of segmental scleral buckling and encircling procedures on tissue circulation in the human optic nerve head (ONH) and choroid and retina. Methods—Using the laser speckle method, the normalised blur (NB) value, a quantitative index of tissue blood velocity, was measured every 0.125 seconds and averaged over three pulses in the optic nerve head (NBONH) and choroid and ret...

purpose: to compare the success rate of adjunctive 5-fluorouracil (5-fu) and low molecular weight heparin (lmwh), and daunomycin in combination with triamcinolone during vitrectomy in eyes with retinal detachment (rd) and proliferative vitreoretinopathy (pvr). methods: in this prospective randomized clinical trial, 69 eyes from 69 patients with rd and pvr (grade b or c) randomized to 3 groups. ...
