Immune reconstitution inflammatory syndrome (IRIS) presents as an exaggerated immune reaction that occurs during dysregulated restoration in immunocompromised patients late-stage human immunodeficiency virus (HIV) infection who have commenced antiretroviral treatments (ART). Virtually any opportunistic pathogen can provoke this type of disorder. In review, we focus on recent developments the id...
ethanolic crude extract of i. imbricata lindl. (iridaceae) was subjected to column chromatography on silica gel with varying portions of meoh: chcl3. nigicin (irisolone) was isolated and its identification carried out by ir, uv, ms, 1-d and 2-d nmr spectroscopy.
purpose: to evaluate the outcomes and complications of phacoemulsification and posterior chamber intraocular lens implantation (pe+pciol) in patients with congenital iris coloboma. methods: in a prospective noncomparative interventional case series, 13 eyes of 9 patients (six female and three male) with congenital iris coloboma and cataract underwent pe+pciol using clear corneal incision and in...
Hypoxia-induced VEGF governs both physiological retinal vascular development and pathological retinal neovascularization. In the current paper, the mechanisms of physiological and pathological neovascularization are compared and contrasted. During pathological neovascularization, both the absolute and relative expression levels for VEGF 164 increased to a greater degree than during physiologica...
PURPOSE This study was performed to examine the vascular network of the human iris using flat preparation. METHODS The ciliary body-iris structures were separated from human eyeballs, and a portion of the irises were treated with trypsin to remove the pigment granules. These iris tissues were unfolded and placed onto glass slides using flat preparation, and the vascular network of each iris w...
Iris recognition used the iris features to verify and identify identity of human. The has many advantages such as stability over time, easy use high accuracy. However, poor quality images can degrade accuracy system. this system is depended on pattern captured during acquisition. due blurry image. Blurry image happened movement acquisition camera resolution. Due that, a deblurring method based ...
