CSF normally flows back and forth through the aqueduct during the cardiac cycle. During systole, the brain and intracranial vasculature expand and compress the lateral and third ventricles, forcing CSF craniocaudad. During diastole, they contract and flow through the aqueduct reverses. Hyperdynamic CSF flow through the aqueduct is seen when there is ventricular enlargement without cerebral atro...

Multiscale information system is a new knowledge representation system for expressing the knowledge with different levels of granulations. In this paper, by considering the unknown values, which can be seen everywhere in real world applications, the incomplete multiscale information system is firstly investigated. The descriptor technique is employed to construct rough sets at different scales ...

In present investigation, the effect of egg albumin on the rate of dissolution of analgesic tablets has been studied. Three sets of binder containing egg albumin in different ratios were used to prepare laboratory scale formulations and their dissolution behavior was studied. The best result was achieved from formulation having all the three binders (egg albumin, gelatin and corn starch) in 1:1...

The approximation space definition has evolved in rough set theory over the last 15 years. The aim was to build a unified framework for concept approximations. We present an overview of this evolution together with some operations on approximation spaces that are used in searching for relevant approximation spaces. Among such operations are inductive extensions and granulations of approximation...

Woodfordia fruticosa is a high demand medicinal plant for pharmaceutics and dye industries. The plant is distributed in North-eastern India. This review highlights the spectacular properties of this plant. Flowers of W. fruticosa have been used traditionally in the treatment of dysentery, diarrhea, other bowel complaints, internal haemorrhages, leucorrhoea and menorrhagia. Externally, powdered ...

Intravasation of Pantopaque at myelography is usually related to entry or partial entry of a spinal needle into an epidural vein . This may occur initially, while positioning a spinal needle, or during repuncture for removal of contrast agent. We observed an atraumatic lumbar puncture at the L3-L4 interspace made with a single pass, in which intravasation of contrast material occurred in the mi...

The problem of concept formation and learning is examined from the viewpoint of granular computing. Correspondences are drawn between granules and concepts, between granulations and classifications, and between relations over granules and relations over concepts. Two learning strategies are investigated. A global attribute-oriented strategy searches for a good partition of a universe of objects...

Giant arachnoid granulations (AG) can mimic intracranial lesions. Knowledge of these structures can help avoid misdiagnosis when interpreting imaging. Here, we report a child who presented with a mass within the superior sagittal sinus and an anomalous draining vein. Herein, the diagnosis of a giant AG was made. Clinicians who view or interpret imaging of the head should be aware of these anato...

Symptomatic respiratory tract involvement with granulomatous bronchial lesions has not yet been described in Crohn's disease. We report two patients with colonic Crohn's disease and severe respiratory symptoms (dyspnoea associated in one of the patients with voicelessness); erythema, aphthoid and superficial ulcerations were found in the colon and whitish granulations in the bronchi at endoscop...
