Background. While the surface of a cell normally has some amount of somatostatin receptors, these receptors are overexpressed to a very high degree in multiple neoplastic diseases. No data exist for esophageal carcinoma. Purpose. To find out whether esophageal carcinoma could be imaged using somatostatin receptor scintigraphy. Material and Methods. 34 patients with esophageal lesions were prosp...

AIM OF THE STUDY This study aimed at integrating research discussing the role of perceived psychosocial barriers in cervical cancer screening (CCS) uptake. In particular, we analyzed the evidence for the associations between CCS uptake and perceived psychosocial barriers and frequency of psychosocial barriers identified by women. MATERIAL AND METHODS A systematic search of peer-reviewed paper...

Extracellular vesicles (EVs) enable the exit of regulatory, mutant and oncogenic macromolecules (proteins, RNA and DNA) from their parental tumor cells and uptake of this material by unrelated cellular populations. Among the resulting biological effects of interest is the notion that cancer-derived EVs may mediate horizontal transformation of normal cells through transfer of mutant genes, inclu...

Plasma membrane vesicles isolated from nontransformed and Simian virus 40-transformed mouse fibroblast cultures catalyzed carrier-mediated D-glucose transport without detectable metabolic conversion to glucose &phosphate. Glucose transport activity was stereospecific, temperature-dependent, sensitive to inactivation by p-chloromercuriphenylsulfonate, and accompanied plasma membrane material dur...

ABSTRACT- The effects of iron (Fe) and zinc (Zn) treatments on the growth and nutrient composition of chickpea were studied in a greenhouse experiment arranged in a completely randomized design. While the application of Fe decreased mean shoot dry weight of chickpea, that of Zn had no significant effect on chickpea shoot dry weight. Increasing Fe levels drastically decreased Mn concentration an...

Several challenges exist for successful nanoparticle cellular uptake—they must be able to cross many physical barriers reach their target and overcome the cell membrane. A strategy this challenge is exploit natural uptake mechanisms namely passive endocytic (i.e., clathrin- caveolin-dependent/-independent endocytosis, macropinocytosis phagocytosis). The influence of material size well documente...

Rock colonization by plant roots and their associated microbiota is one of the major drivers of mineral weathering, nutrient cycling, soil formation and ecosystem stability. Yet the mechanisms of biouptake of lithogenic elements from rocks with differential nutrient availabilities and limitations are yet to be established. Here we present results from a mesocosm experiment that examined lithoge...

The low initial Coulombic efficiency (ICE) for the electrodes which stems from electrolyte decomposition and irreversible sodium uptake by material itself, is one of reasons limiting large-scale sodium-ion capacitors (SICs). Here, we report a simple but precise bifunctional pre-sodiation Nb2O5 anode (as typical example) using naphthalene/2-methyltetrahydrofuran as pre-sodiated agent. agent real...

this study was carried out in order to evaluate the changes of nitrogen, phosphor and potassium uptake by wheat and remaining of them in soil under foliar application of leonardite and foliar application of n and k. the experiment was conducted in gorgan university of agricultural sciences and natural resources during 2013- 2014. the experiment was laid out a using split-plot arrangement based ...

wheat (triticum aestivum l.) was grown in earthen pots containing soil of balkasar soil series (sandy loam) in green house at the department of soil science and swc, pir mehr ali shah arid agriculture university, rawalpindi during rabi season, 2007. the crop was treated with two levels of phosphorus (40 and 80 kg p ha-1 ) in the form of ssp, tsp, np and dap. a basal doze of 100 kg n and 60 kg k...
