BACKGROUND Vorinostat (suberoylanilide hydroxamic acid) is the first histone deacetylase inhibitor approved by US FDA for use in oncology. However, as a hydrophobic acid, its limited aqueous solubility poses a problem for parenteral delivery. Such limited solubility may also affect its oral bioavailability. OBJECTIVE The aim of this study was to evaluate(More)
Cone mill was well studied for milling of wet agglomerates. This study evaluated the effects of various process parameters of cone milling roller compacted flakes on the granules produced. Impeller sidearm shapes, screen surface profiles and impeller speeds were studied. Impeller speed was found to play a major role in determining the granule attributes.(More)
AIMS To investigate if two important epidemic viral encephalitis in children, Enterovirus 71 (EV71) encephalomyelitis and Japanese encephalitis (JE) whose clinical and pathological features may be nonspecific and overlapping, could be distinguished. METHODS Tissue sections from the central nervous system of infected cases were examined by light(More)
Cone mill is commonly used for the milling of wet and dry agglomerates in the pharmaceutical industry as it is capable of producing milled granules with desired size characteristics. The aim of this study was to evaluate the various cone mill process parameters in terms of milling rate and energy consumption for the comminution of roller compacted flakes. A(More)
This study assessed the utility of near-infrared (NIR) spectroscopy for the real-time monitoring of content uniformity and critical quality attributes (tensile strength, Young’s modulus, and relative density) of ribbed roller compacted flakes made by axially corrugated or ribbed rolls. A custom-built setup was used to capture off-line NIR spectra from the(More)
