Macular xanthophylls, lipoprotein-related genes, and age-related macular degeneration.
Plant-based macular xanthophylls (MXs; lutein and zeaxanthin) and the lutein metabolite meso-zeaxanthin are the major constituents of macular pigment, a compound concentrated in retinal areas that are responsible for fine-feature visual sensation. There is an unmet need to examine the genetics of factors influencing regulatory mechanisms and metabolic fates of these 3 MXs because they are linke...

amd بیماری تحلیل شبکیه است که عامل اصلی کوری در افراد بالای 55 سال در جهان غرب به شمار می-رود. در اثر این بیماری، لیپوپروتئین ها در شبکیه تجمع پیدا کرده و رگ زایی القاء می شود. ثابت شده است که عوامل ژنوتوکسیک محیطی مثل سیگار کشیدن، رژیم غذایی و نور در افراد پیر با زمینه ی ژنتیکی مستعد در بروز بیماری دخیل می باشند. بنابراین ما یک مطالعه ی مـورد- شاهـدی را ترتیب دادیم که شـامل 112 فرد مبتلا به am...
Macular pigment and age related macular degeneration.
The present concepts of the pathogenesis of AMD include cumulative light damage by oxidative processes in the macular photoreceptors as environmental co-factor for the development of AMD. The direct causative connection of this hypothesis has still to be established but wide circumstantial evidence from epidemiological and basic scientific investigations are strongly supportive. Macular pigment...
متن کاملthe genetics of age-related macular degeneration
age-related macular degeneration (amd) is the leading cause of blindness in old subjects. it is a multifactorial disease with both environmental and genetic factors playing some role in its pathogenesis. similar to many other genetic diseases, the inheritance pattern of amd does not fit into simple mendelian rules. these diseases are caused by the presence of multiple genetic factors and are ca...
