This paper concerns the reconstruction of the absorption and scattering parameters in a time-dependent linear transport equation from full knowledge of the albedo operator at the boundary of a bounded domain of interest. We present optimal stability results on the reconstruction of the absorption and scattering parameters for a given error in the measured albedo operator.

homalium letestui pellegr (flacourtiaceae) is used traditionally by the ibibios of southern nigeria to treat stomach ulcer, malaria and other inflammatory diseases and yorubas of western nigeria as an antidote. the hepatoprotective effect of the stem extract (200-600 mg/kg) was evaluated by the assay of liver function parameters, namely total and direct bilirubin, serum protein and albumin, tot...

PURPOSE To evaluate the roles of dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) and optimum tracer kinetic parameters in the noninvasive grading of the glial brain tumors with histopathological grades (I-IV). MATERIALS AND METHODS Twenty-eight patients with histopathologically graded gliomas were imaged. Images with five flip angles were acquired before injection of gadolinium...

The present study was conducted to evaluate the effect of alcoholic extract A.webbiana leaves Lindl on liver and kidney. Wistar rats were divided into three groups (n=3) for hepatotoxicity and nephrotoxicity. Alcoholic leaves extract of A.webbiana was evaluated for protective effects against CCl4 induced hepatotoxicity and cisplatin induced nephrotoxicity. Hepatotoxicity studied by comparing pa...

Conventionally, the juice and extract of Alangium salvifolium leaves have been used for the treatment of diabetes, wound healing, dog bite, and as a poultice in rheumatism. To carry out the sub-chronic toxicity and thereafter safety evaluation of A. salvifolium leaves. The aqueous extract of A. salvifolium leaves was administered orally at the doses of 200, 400, and 800 mg/kg/day for 90 days. A...

The human body is exposed nowadays to increasing attacks by toxic compounds in polluted air, industrially processed foods, alcohol and drug consumption that increase liver toxicity, leading to more and more severe cases of hepatic disorders. The present paper aims to evaluate the influence of the apitherapy diet in Wistar rats with carbon tetrachloride-induced hepatotoxicity, by analyzing the b...

Capsule Shaqeeqa, Unani formulation, is prescribed for the clinical treatment of diseases like sinusitis, headache, and migraine. The safety evaluation data of it is not available; in order to provide the safety data the present study was carried out. The study was carried out on four groups of rats (n = 5). Two groups (one male and one female group) as normal controls were orally given water w...
