The high sensitivity of pentagastr in stimulation in detecting pr imary or metastatic medullary thyroid cancer (MTC) suggests widespread expression of the corresponding receptor type on human MTC. Indeed, autoradiographic studies demonstrated cholecystokinin (CCK)-B/gastrin receptors not only in >90% of MTCs but in a high percentage of small cell lung cancers and potentially a variety of gastro...

A field experiment was conducted to study the response of wheat and rice to potassium during 2004-05. The basal dose of N at 120 kg, P2O5 at 90 kg ha -1 was applied with K levels to both wheat and rice crops. Wheat variety Naseer 2000 and rice variety IRRI 6 were used in the study. The experiment was carried out in R.C.B design with three replications. Potassium application significantly increa...

Phalaenopsis is the second most valuable potted plant in the United States. Information on the genetic diversity and relationships among species and hybrids is important for breeding purposes and species conservation. In this study, genetic variability of 16 Phalaenopsis species and hybrids was analyzed using amplified fragment length polymorphism (AFLP) markers. Ten AFLP primer combinations am...

Purpose: The activities of insulin-like growth factors (IGFs) in regulating cell proliferation, differentiation, and apoptosis are modulated by a family of high-affinity specific IGF-binding proteins (IGFBPs), especially IGFBP-3, the most abundant IGFBP in circulation. Hypermethylation of the promoter represses the expression of the IGFBP-3 gene. The purpose of this study was to determine wheth...

of agricultural P to water quality. In Florida, FHANTM 2.0 (Field Hydrologic and Nutrient Transport Model, Pollution of surface waters by P from agricultural areas is a water version 2.0; Fraisse and Campbell, 1997) was developed quality issue in Delaware. The FHANTM 2.0 computer model can help identify areas with a high potential for P loss, but the model’s to simulate water and P movement fro...

Accelerated methods for partitioning of Cd, Cr, Cu, Ni, Pb and Zn, such as the use of single and ultrasonic extractions are assessed in terms of readsorption and compared with the three-stage sequential extraction scheme (SES) of the Standards Measurements and Testing Programme (SM&T). The standard addition approach was employed for characterising the readsorption artefact by applying the above...

Municipal sewage sludge can be used as a fertilizer for crops but may also introduce undesirable metals into the food chain, especially when used on acid minesoils. In this study, sewage sludge from Morgantown, WV was surface applied to two acid minesoils and a neutral undisturbed soil to evaluate sludge application rates on forage production, nutrient loadings, and on heavy metal accumulation ...

Purpose:The therapeutic efficacy of a unique melanoma-targeting peptide conjugated with an in vivo generated a-particle-emitting radionuclide was evaluated in the B16/F1mouse melanoma animal model. a-Radiation is densely ionizing, resulting in high concentrations of destructive radicals and irreparable DNA double-strand breaks. This high linear energy transfer overcomes radiation-resistant tumo...

Endothelial lipase (EL) is a phospholipase A1 (PLA1) enzyme that hydrolyzes phospholipids at the sn-1 position to produce lysophospholipids and free fatty acids. Measurement of the PLA1 activity of EL is usually accomplished by the use of substrates that are also hydrolyzed by lipases in other subfamilies such as phospholipase A2 (PLA2) enzymes. In order to distinguish the PLA1 activity of EL f...

L are used commonly in agricultural systems Legume mulches are important sources of N for cereal crop producas a source of N for subsequent crops and for maintion, particularly for organic and resource-poor producers. A field taining soil N levels. This use is particularly important study was conducted using a direct method to determine if the amount in the humid tropics where N fertilizers oft...
