OBJECTIVES To investigate the effect of age, sex, and the Y402H variant in the complement factor H (CFH) gene on the incidence, progression, and regression of age-related macular degeneration (AMD) as well as the effect of these factors and AMD on mortality, using multistate models. METHODS Analyses included 4379 persons aged 43 to 84 years at the time of the census. The status of AMD on a 5-...
امروزه استفاده از افزودنیهای خاک، یکی از فنآوریهای جدید در مقوله مدیریت منابع آب و خاک محسوب میشود. لکن تعیین سطوح بهینه آنها در تعامل با سلامت محیط زیست کم تر مورد توجه قرار گرفته است. از این رو پژوهش حاضر بهمنظور ارزیابی کمّی تأثیر پلی-آکریل آمید (pam) بر مولفههای روانآب و رسوب، میزان رهایش pam و مونومر آکریلآمید (amd) در روانآب و رسوب خروجی از سطح مطالعاتی در شرایط آزمایشگاهی مورد بررسی قرار ...
PURPOSE To establish the relation between AMD stage and a quantitative measure for the integrity of foveal cone photoreceptors related to the optical Stiles-Crawford effect. METHODS Fifty-six AMD eyes and 57 control eyes were included in the final analysis. AMD was graded in accordance with the International Classification System into five mutually exclusive stages. Stages 0 to 1 were labeled...
PURPOSE To examine the association between apolipoprotein E (APOE) polymorphisms and age-related macular degeneration (AMD) in a Chinese population. METHODS The study consisted of 712 subjects, including 201 controls, 363 cases with early AMD, and 148 cases with exudative AMD. Genomic DNA was extracted from venous blood leukocytes. Common allelic variants of APOE (ε2, ε3, and ε4) were analyze...
Introduction & Objective: Age-related macular degeneration (AMD) is a disease affecting the central regions of the retina and choroid, which can lead to loss of central vision. Etiological research suggests that AMD is a complex disease, caused by the actions and interactions of multiple genes and environmental factors. Numerous studies have focused on the role of chemotactic cytokines, also kn...
OBJECTIVE To examine the association between self-reported diabetes history and early or late age-related macular degeneration (AMD) in the European population. METHODS Participants aged 65 years and over in the cross-sectional population-based EUREYE study underwent an eye examination including digital retinal photography. The images were graded at a single centre. A structured questionnaire...
با توجه به رشد بالای جمعیت در جهان و نیاز اطمینان از امنیت غذایی، افزایش تولید واحد سطح محصولات زراعی به‌منزلة راهبردی اساسی حل مسئلة تأمین غذا به‌شمار می‌رود. سوی دیگر، وجود محدودیت زیرکشت پایین‌بودن میانگین عملکرد برخی کشاورزی مانند گندم کشور، محصول می‌تواند راهکاری عملی پاسخ کشور محسوب شود. یکی مهم‌ترین بیماری‌های فوزاریوم است که، نقش پیش‌بینی این بیماری جلوگیری کاهش بهره‌وری محصول، مدل‌هایی...
BACKGROUND Age-related macular degeneration (AMD) is the leading cause of central vision loss in older adults. Anti-retinal autoantibodies (AAbs) have been found in individuals with AMD. The goal of the study was to determine the AAb specificity in different stages of AMD, and determine whether there is a prevalent AAb signature. METHODS Sera of 134 participants in the Age-related Eye Disease...
BACKGROUND Age-related macular degeneration (AMD) is the most common cause of irreversible visual impairment in the developed world. The two forms of advanced AMD, geographic atrophy and neovascular AMD, represent different pathological processes in the macula that lead to loss of central vision. Soft drusen, characterized by deposits in the macula without visual loss, are considered to be a pr...
BACKGROUND/AIMS With the increased efficacy of current therapy for wet age-related macular degeneration (AMD), better ways to detect wet AMD are needed. This study was designed to test the ability of three-dimensional contrast threshold Amsler grid (3D-CTAG) testing to distinguish wet AMD from dry AMD. METHODS Conventional paper Amsler grid and 3D-CTAG tests were performed in 90 eyes: 63 with...
