Loss-of-function mutations in Star impart a dominant rough eye phenotype and, when homozygous, are embryonic lethal with ventrolateral cuticular defects. We have cloned the Star gene and show that it encodes a novel protein with a putative transmembrane domain. Star transcript is expressed in a dynamic pattern in the embryo including in cells of the ventral midline. In the larval eye disc, Star...

Human face detection is often the first step in applications such as video surveill:ance, human computer interface, face recognition, and image database management. We propose a face detection algorithm for color images in the presence of varying lighting conditions as well as complex backgrounds. Our method detects skin regions over the entire image, and then generates face candidates based on...

PARASITIZATION of the human eye by the " gid" worm (genus Multiceps) does not appear to have been recorded hitherto. The following two cases are therefore reported. Case Reports Case 1, a male Ankole native of Ugandi, aged 21, attended in January, 1954, complaining that his left eye had been painful for one week. There was ciliary injection, profuse fine precipitates, and a marked aqueous flare...

Although glial cells have been implicated widely in the formation of axon tracts in both insects and vertebrates, their specific function appears to be context-dependent, ranging from providing essential guidance cues to playing a merely facilitory role. Here we examine the role of the retinal basal glia (RBG) in photoreceptor axon guidance in Drosophila. The RBG originate in the optic stalk an...

the present study was undertaken to develop a suitable transdermal matrix patch of ketorolac tromethamine with different proportions of polyvinyl pyrrolidone (pvp) and ethyl cellulose (ec) using a d-optimal mixture design. the prepared transdermal patches were subjected to different physicochemical evaluation. the surface topography of the patches was examined by scanning electron microscopy (s...

Habitat loss is a significant driver of biodiversity loss, causing fragmentation into small, isolated patches suitable land cover. This reduces the permeability landscapes to movement individuals and likelihood metapopulation persistence. Quantifying functional connectivity, ability focal species move between resource patches, therefore essential for conservation management. There substantial e...
