Choroidal folds and papilloedema.
AIMS To assess the clinical and fluorescein angiographic features of choroidal folds seen in association with papilloedema. METHODS In a retrospective study, the clinical data from a database on patients with choroidal folds (1963-97), including fundus photography and fluorescein angiography, from 32 patients (64 eyes) with choroidal folds in association with papilloedema were reviewed. The c...
متن کاملProtein folds and functions.
BACKGROUND The recent rapid increase in the number of available three-dimensional protein structures has further highlighted the necessity to understand the relationship between biological function and structure. Using structural classification schemes such as SCOP, CATH and DALI, it is now possible to explore global relationships between protein fold and function, something which was previousl...
متن کاملBilateral Choroidal Folds in a Diabetic Patient
Abstract In this presentation, a case of bilateral choroidal folds in patient with diabetic retinopathy was reported. By our knowledge, this case presentation is the first report of choroidal folds in diabetic retinopathy, which bilateral symmetric and horizontal folds arranged in macula. The thick choroid that is developed in diabetics may be a cause of these folds but the source of differenc...
متن کاملProtein folds, functions and evolution.
The evolution of proteins and their functions is reviewed from a structural perspective in the light of the current database. Protein domain families segregate unequally between the three major classes, the 32 different architectures and almost 700 folds observed to date. We find that the number of new topologies is still increasing, although 25 new structures are now determined for each new to...
متن کاملProtein folds and protein folding.
The classification of protein folds is necessarily based on the structural elements that distinguish domains. Classification of protein domains consists of two problems: the partition of structures into domains and the classification of domains into sets of similar structures (or folds). Although similar topologies may arise by convergent evolution, the similarity of their respective folding pa...
