in this theoretical study, the effect of various types of bypass graft angles on the flow field, has been investigated specially on the temporal wall shear stress (wss) on the toe, heel and some locations on the bed of the left anterior descending (lad) artery at the anastomoses areas in the aorto-coronary (ac) and coronary-coronary (cc) bypasses. flow fields in both bypasses with angles of 20º...

Of various techniques of pteryium surgeries to prevent recurrence, conjunctival limbal auto graft has been the most successful adjuvant since studies have shown role stem cell deficiency (LSCD) as pathology pterygium. The common method auto-graft fixation post pterygium excision is suturing; with drawbacks prolonged operating time and postoperative discomfort. Replacing sutures tissue adhesives...

This study aims at exploring an effective route in the in situ graft polymerization of aniline from Fe3O4 nanoparticles. To this goal, Fe3O4 magnetic nanoparticles were prepared by coprecipitation method using ammonia solution as the precipitating agent, and were characterized by Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) and transmission electron microscopy (TEM)....

green vine of the parasitic dodder plant (Cuscuta) latching onto a host plant. Christian Hettenhausen et al. found that Cuscuta bridges between host plants facilitate the transfer of herbivoryinduced signals from attacked to unattacked host plants. The authors report that the jasmonic acid biosynthesis pathway is required to generate such interplant signaling, which elevates defensive metabolit...
