SiO2 is the most abundant oxide in the earth and its properties, behaviors and interactions are of immense scientific and technological importance. Of particular importance are the interactions of silica with aqueous fluids because these fluids are present in nearly every natural setting. The dissolution of silica and glass by HF plays a very important role in technology and is widely used for ...

Wegeners granulomatosis is a necrotizing granulomatous vasculitis with multisystemic involvement. We present two cases of Wegener's presenting with otological manifestations as the first symptom. These symptoms are subtle and diagnosis may be easily overlooked. Hence a high index of suspicion is required.

The association of angiitis of central nervous system (ACNS) with cerebral amyloid angiopathy (CAA) suggests a physiopathological relationship between these two affections. Few cases are reported in patients with Alzheimer's disease (AD). We describe here a clinicopathological case associating ACNS, CAA, and AD. We discuss the aetiology of ACNS and its relationship with cerebral deposition of b...
