BACKGROUND Immune reconstitution inflammatory syndrome (IRIS) reflects an aberrant immune response that can develop in human immunodeficiency virus-infected patients initiating antiretroviral therapy (ART). Its pathogenesis remains unclear. METHODS We performed a nested case-control study using specimens from ACTG A5164. We compared plasma biomarkers and T-cell subsets in 19 IRIS and 39 contr...

Article Information The non-intrusive property of iris recognition leads to several problems to the images of natural-open eyes and it is hard to increase the accuracy of iris recognition because of these problems. In order to ensure the non-intrusive property as well as achieve an iris recognition which has high accuracy simultaneously, this paper presents a novel iris recognition method based...

The roles of the iris microvasculature have been increasingly recognised in the pathogenesis of glaucoma and cataract; however limited information exists regarding the iris microvasculature and its endothelium. This study quantitatively assessed the iris microvascular network and its endothelium using intra-luminal micro-perfusion, fixation, and staining of the porcine iris. The temporal long p...

Iris recognition has been developing for over 20 years, but, only in recent years has it been more accessible and widely accepted as one of the most accurate and un-obtrusive biometric modalities. Over the past few years, many companies have developed iris acquisition systems that are more user-friendly. Iris-On-the-Move (IOM) is one such system, offering significant stand-off acquisition dista...

purpose : we describe our experience on safety and effectiveness of phacoemulsification in cataract and congenital iris coloboma and point out some specific surgical recommendations aimed to minimize its complications. methods : a prospective case series study was conducted on nineteen consecutive patients with cataract and congenital iris coloboma referred to the farabi eye hospital in tehran....

A third of adults with AIDS and cryptococcal meningitis (CM) develop immune reconstitution inflammatory syndrome (IRIS) after initiating antiretroviral therapy (ART), which is thought to result from exaggerated inflammatory antigen-specific T cell responses. The contribution of monocytes to the immunopathogenesis of cryptococcal IRIS remains unclear. We compared monocyte subset frequencies and ...

Iris-based biometric system is gaining its importance in several applications. However, processing of iris biometric is a challenging and time consuming task. Detection of iris part in an eye image poses a number of challenges such as, inferior image quality, occlusion of eyelids and eyelashes etc. Due to these problems it is not possible to achieve 100% accuracy rate in any iris-based biometri...

Floral visitors of the homoploid hybrid speeies. Iris nelsonii (Abbeville Red Iris), were observed and identified in order to determine whether Abbeville Red Iris flowers are visited by similar floral visitors as its progenitor Iris speeies. The most common floral visitors to Abbeville Red Iris flowers v/exeArchilochus colubris (Ruby-throated Hummingbird), whieh were also largely successful in ...

Purpose We previously identified three distinct subgroups of patients with primary angle closure glaucoma (PACG) based on anterior segment optical coherence tomography (ASOCT) imaging. Group 1 was characterized by a large iris area with deepest anterior chambers, group 2 by a large lens vault (LV) and shallow anterior chamber depth (ACD), and group 3 displayed intermediate values across iris ar...
