BACKGROUND To report a case of complete progressive visual recovery and healing of outer retinal layers after vitrectomy for foveal detachment associated with optic disc pit. CASE PRESENTATION Optical coherence tomography (OCT) follow-up was performed on a 15-year-old boy with deep optic disc pit and foveal detachment, before and for 10 years after vitrectomy with gas. The foveal detachment w...

In order to better understand the detachment mechanism of secondary dendrite arm during peritectic solidification, the detachment of secondary dendrite arm from the primary dendrite arms in directionally solidified Sn-36at.%Ni peritectic alloys is investigated at different deceleration rates. Extensive detachment of secondary dendrite arms from primary stem is observed below peritectic reaction...

Rhegmatogenous retinal detachment (RRD) is a vision-threatening disorder. Although successful repair of RRD, incomplete visual recovery, color vision defects, or persistent metamorphopsia may be still persist. Recent advances in retinal imaging have improved resolution to survey retinal pathologic changes. Spectral-domain optical coherence tomography (SD-OCT) is a non-contact real-time system w...

Most studies on articular cartilage properties have been conducted after detachment of the cartilage from the bone. In the present work we investigated the effect of detachment on collagen fiber architecture. We used one-dimensional H double quantum filtered MRI on cartilage bone plugs equilibrated in deuterated saline. The quadrupolar splittings observed in the different zones were related to ...

Seismic tomography models of the three-dimensional upper mantle velocity structure of the Mediterranean-Carpathian region provide a better understanding of the lithospheric processes governing its geodynamical evolution. Slab detachment, in particular lateral migration of this process along the plate boundary, is a key element in the lithospheric dynamics of the region during the last 20 to 30 ...

The adult mammalian retinal pigment epithelium (RPE) is mitotically inactive, yet retains the capacity to proliferate under certain conditions. To determine the onset of RPE proliferation after retinal detachment, we examined experimentally detached cat retinas of 12, 24, 48, and 72 hr duration. An additional animal served as a nondetached, sham-operated control. 3H-thymidine was injected into ...

Subduction initiation is a critical link in the plate tectonic cycle. Intraoceanic subduction zones can form along transform faults and fracture zones, but how subduction nucleates parallel to mid-ocean ridges, as in e.g., the Neotethys Ocean during the Jurassic, remains a matter of debate. In recent years, extensional detachment faults have been widely documented adjacent to slow-spreading and...

Results: The junctional zone showed basement membrane thickening and the vessels showed endothelial interruptions. Some endothelial cells were degenerated and a few were apoptotic. Endothelial cells showed increased microfilaments with foci of detachment from the underlying basement membrane. Larger blood vessels showed large plump endothelial cells alternating with attenuated ones. There was a...

abstract microbial contaminants transport to groundwater is a serious environmental problem that can result in large outbreaks of waterborne diseases. some of bacteria can travel from vadose zone and cause contamination of groundwater resources. thus, an accurate prediction of transport and fate of pathogenic microorganisms in unsaturated soil is needed to protect groundwater resources. the mai...
