Leopard spot retinal pigmentation in infancy indicating a peroxisomal disorder.
BACKGROUND Neonatal adrenoleucodystrophy (NALD) is a rare disorder resulting from abnormal peroxisomal biogenesis. Affected patients present in infancy with developmental delay, hypotonia, and seizures. Blindness and nystagmus are prominent features. The authors suggest a characteristic leopard spot pigmentary pattern in the peripheral retina to be diagnostic. METHODS Three patients are repor...
متن کاملLeopard: A Locality Aware Peer-to-Peer System with No Hot Spot
Recent research [7, 12, 2] has shown that Internet hosts can be efficiently (i.e., without excessive measurements) mapped to a virtual (Euclidean) coordinate system, where the geometric distance between any two nodes in this virtual space approximates their real IP network distance (latency). Based on this result, in this paper, we propose an alternative approach that inherently incorporates a ...
متن کاملLeopard: A Location-Aware Peer-To-Peer System With No Hot Spot
We propose an alternative approach for building structured peer-to-peer systems. The major design objectives are i) to explicitly incorporate locality information into the system to minimize routing stretch in object look-up service, and ii) to inherently better cope with the “flash crowd” problem. Unlike the standard DHT-based approach, where both objects and nodes are assigned a randomly hash...

Spot pattern of Leopard Danio is caused by the mutation in zebrafish connexin41.8 gene
متن کاملSpot pattern of leopard Danio is caused by mutation in the zebrafish connexin41.8 gene.
Leopard, a well-known zebrafish mutant that has a spotted skin pattern instead of stripes, is a model for the study of pigment patterning. To understand the mechanisms underlying stripe formation, as well as the spot variation observed in leopard, we sought to identify the gene responsible for this phenotype. Using positional cloning, we identified the leopard gene as an orthologue of the mamma...
