In vivo efficacy of NRL knockdown with cell-penetrating siRNA in retinal degeneration

Scientific Reports
Retinal degenerative diseases, such as retinitis pigmentosa (RP) and age‑related macular degeneration (AMD), lead to progressive vision loss through photoreceptor degeneration; RP begins with the gradual loss of peripheral rods, whereas AMD causes ...

Single Well Coning Problem and Applicable Solutions

Iraqi Journal of Chemical and Petroleum Engineering, 2015
One of the most important and common problems in petroleum engineering; reservoir, and production engineering is coning; either water or gas coning. Almost 75% of the drilled wells worldwide contains this problem, and in Iraq water coning problem is much wider than the gas coning problem thus in this paper we try to clarify most of the reasons causing ...

Identification and characterization of early human photoreceptor states and cell-state-specific retinoblastoma-related features

eLife
Human cone photoreceptors differ from rods and serve as the retinoblastoma cell-of-origin, yet the developmental basis for their distinct behaviors is poorly understood. Here, we used deep full-length single-cell RNA-sequencing (scRNA-seq) to distinguish
