This paper presents a novel method for direct detection of Plasmodium falciparum histidine rich protein-2 (PfHRP-2) antigen using carbon nanofiber (CNF) forests grown on glass microballoons (NMBs). Secondary antibodies specific to PfHRP-2 densely attached to the CNFs exhibit extraordinary ability for the detection of minute concentrations of Plasmodium species. A sandwich immunoassay protocol w...

Most of the floating systems have an inherent drawback of high variability in the GI transit time, invariably affecting the bioavailability of drug. An attempt has been made to develop floating drug delivery system for improving the drug bioavailability by prolongation of gastric residence time of famotidine in stomach. The floating microballoons were prepared using polymer Eudragit L-100 by so...

Magnesium (Mg)/glass microballoons (GMB) metal matrix syntactic foams (1.47-1.67 g/cc) were synthesized using a disintegrated melt deposition (DMD) processing route. Such syntactic foams are of great interest to the scientific community as potential candidate materials for the ever-changing demands in automotive, aerospace, and marine sectors. The synthesized composites were evaluated for their...

We describe two cases in which balloons were used to aid in the occlusion of intracranial aneurysms with Guglielmi detachable coils. In both patients, initial attempts to place coils within the aneurysmal sac failed, as the loops of the coil repeatedly protruded through a wide aneurysmal neck into the parent vessel. Temporary balloons placed across the neck of these small, wide-necked aneurysms...

Objective: The present work was to formulate buoyant system in order to protect the drug from gastric acid degradation, increasing the gastric residence time, control the drug leaching by use of enteric polymers, prolong the half life for longer duration of action, furthermore to prevent dosage form adherence to the mucous wall in order to avoid incomplete drug release. Moreover the side effect...

LLE is presently involved in a series of experiments 'intended to demonstrate the ability of direct-drive laser fusion to ablatively compress microencapsulated deuterium-tritium (DT) fuel to 200 times its liquid density. This campaign has been structured into three parts. The first part was initiated in February 1985 and involved the implosion of glass microballoons filled with various pressure...
