Preparation of alginate fibers coagulated by calcium chloride or sulfuric acid: Application to the adsorption of Sr.

The adsorption behavior of Sr over alginate (Alg) fibers prepared by wet spinning was investigated. Different grades of sodium alginate (Alg-Na) were chosen. The Alg fibers were obtained by coagulation of 1% HSO (Alg-acid) or 5% CaCl (Alg-Ca) solutions.

Huge arachnoid cyst of the occipital cerebral convexity.

A 68-year-old woman presented with a rare huge right occipital cystic lesion manifesting as progressive left hemiplegia. Cranial computed tomography revealed a 4 x 7 cm right occipital lobe thin-walled cyst with midline shift and compression of the ipsilateral ventricle. The patient underwent a single burr hole operation for cystography and delineation of the cyst anatomy, then a separate right parieto-occipital craniotomy with complete cyst evacuation, corticotomy, and ventriculostomy.
