Retro-chiasmal lesions almost always give rise to homonymous field defects with only one exception. The nasal visual field extends to 60% of the horizon, whereas the temporal field extends to a further 30°-40° beyond that; this part of the visual field is represented on the contralateral anterior parieto-occipital sulcus. A lesion in this area will give rise to monocular visual field defect aff...

Bucillamine is a disease-modifying antirheumatic drug that is structurally similar to D-penicillamine. The major renal side effect of bucillamine and D-penicillamine is proteinuria caused by membranous nephropathy (MN). In addition to MN, combined crescent formation has been occasionally reported in D-penicillamine-induced MN, while crescent formation has been rarely reported in bucillamine-tre...

We here describe a case with bilateral optic disc pit and bilateral assymetrical grey crescent, its ocular coherence tomography findings and the associated unilateral maculopathy in the eye with incomplete crescent.The interesting observation is that the eye in which the grey crescent encompassed the optic pit did not have any maculopathy in contrast to the other eye which had macular retinosch...

Cereal agriculture originated with the domestication of barley and early forms of wheat in the Fertile Crescent. There has long been speculation that barley was domesticated more than once. We use differences in haplotype frequency among geographic regions at multiple loci to infer at least two domestications of barley; one within the Fertile Crescent and a second 1,500-3,000 km farther east. T...

The air crescent sign is a well-known important diagnostic finding in invasive pulmonary aspergillosis. Herein we report a distinctive but rare ultrasonographic appearance in a patient with myositis secondary to Aspergillus flavus infection, which can be considered as the soft tissue counterpart of the air crescent sign.

To determine the spectrum of secreted proteins that are present in the extracellular space of early Xenopus embryos, a direct secretion screen was performed. Surprisingly, 24% of previously identified bona fide secretory proteins corresponded to four secreted Wnt antagonists of the same family: frzb-1, sizzled, sfrp-2 and crescent. sfrp-2 and crescent are novel components of the growing cocktai...
