Apart from describing the transport behaviors to a reliable accuracy, it remains as yet far satisfactory comprehend explicit role of solvent–colloid interaction on diffusivity and viscosity colloidal hard-sphere suspensions. Here, we exploit free volume effect by means statistical mechanics, which enables express them in terms solvent–solvent, colloid–colloid, pair correlation functions functio...

Our recent study reported that conformation change of granule-associated Bovine Serum Albumin (BSA) may influence the role of the protein controlling colloid deposition in porous media (Flynn et al., 2012). The present study conceptualized the observed phenomena with an ellipsoid morphology model, describing BSA as an ellipsoid taking a side-on or end-on AC C EP TE D M AN U SC R IP T ACCEPTED M...

This work employed numerical experiments simulating colloid and solute transport in single parallel-plate fractures, using the random walk particle tracking method, to demonstrate that (1) there exists an aspect ratio of the colloid radius to half the fracture aperture, delta(o), where the average velocities of colloids and solutes are similar. When delta>delta(o), the velocity distribution ass...

The paper contains a description of the fine structure of the thyroid gland of the normal rat. The follicular colloid, a homogeneous substance of faintly granular texture, is bounded by cuboidal or low columnar epithelial cells. Numerous pleomorphic microvilli, often permeated by small vesicles extend from the apices of the epithelial cells into the colloid. Many small, membrane-limited vesicle...

UNLABELLED Synchrotron-based X-ray fluorescence microscopy (XFM) can localise chemical elements at a subcellular level. 99mTechnetium stannous (TcSn) colloid is taken up by phagocytes via a Complement Receptor 3 mediated phagocytic process. In the current study, XFM was used to examine the intracellular trafficking of TcSn colloid in neutrophils. XFM was performed on TcSn colloid, and neutrophi...

Six patients with masses of the anterosuperior portion of the third ventricle were imaged with MR and CT. Four patients had proved colloid cysts, one patient had a proved astrocytoma, and one patient had a presumed colloid cyst. Multiplanar MR imaging provided accurate localization of the anterosuperior third-ventricle mass in all cases. The MR intensity characteristics of the colloid cysts var...

[1] We report results on the effects of porewater pH and transients in porewater flow on the deposition and mobilization of colloid-sized clay particles within unsaturated sand columns. The deposition rates of illite under steady-flow conditions were essentially independent of pH, while the deposition rates of kaolinite nearly doubled as the pH decreased from 7.4 to 4.6. Mobilization of kaolini...

OBJECTIVE "Open" transcortical and transcallosal approaches allow gross total colloid cyst resection but require a wider surgical corridor through normal brain tissue compared with endoscopic techniques. Although the use of tubular retractor systems has been previously reported, the minimum required diameter size for the retractor tube has been approximately 16 to 22 mm. Our objective was to ex...

BACKGROUND Ga-labeled radiotracers are increasingly used for PET imaging. During the labeling procedure, formation of (68)Ga-colloid may occur. Upon i.v. injection, (68)Ga-colloid will accumulate rapidly in the liver, spleen, and bone marrow, resulting in reduced target-to-background ratios. In this study, we applied a thin layer chromatography (TLC) method to measure colloid content and we stu...
