Number of retrieved lymph nodes and survival in node-negative patients undergoing laparoscopic colorectal surgery for cancer
The number of retrieved lymph nodes in colorectal cancer resection may have an impact on staging and survival. Examination of at least 12 nodes has become a quality measure for adequate surgical practice. To e...

Modeling adsorption-desorption processes of Cu on montmorillonite and the effect of competitive adsorption with a cationic pesticide
The effect of the ionic strength on adsorption of Cu on Ca-montmorillonite (SAz-1) was studied at concentrations ranging from 31 to 516 µM. An adsorption model was employed in the analysis of the data. When th...

Modeling Adsorption-Desorption Processes of Cd on Montmorillonite
Adsorption-desorption of Cd to Ca montmorillonite (SAz-1) was studied at concentrations ranging from 44.5 to 266.8 μM. An adsorption model was employed in the analysis of the data. The procedure consists of solvi...

Quantitative competition of calcium with sodium or magnesium for sorption sites on plasma membrane vesicles of melon (Cucumis melo L.) root cells
The presence of Ca2+ ions in solution is vital for root growth. The plasma membrane is one of the first sites where competition between Ca2+ and other ions occurs. We studied the competition between Ca2+ and Na+ ...

Use of Methylene Blue and Crystal Violet for Determination of Exchangeable Cations in Montmorillonite
A procedure for the determination of cation exchange capacity (CEC) and the amounts of exchangeable cations adsorbed to montmorillonite is proposed. The method consists of a single incubation of the clay in a ...

Model for Competitive Adsorption of Organic Cations on Clays
The adsorption on montmorillonite of two monovalent organic cations, methylene blue (MB) and thioflavin T (TFT), was studied in four different situations: (1) separate adsorption of MB or TFT; (2) competitive ...

On the mass dependence of diffusion within biological membranes and polymers
A simple probability argument suggests that the diffusion coefficient for biological membranes (and polymers) should vary exponentially with the reciprocal of the molecular weight of the diffusant. A test of t...
