Since various bio-mechanical assays have been introduced for studying mechanical properties of biological samples, much progress has been made in cancer biology. It has been noted that enhanced mechanical deformability can be used as a marker for cancer diagnosis. The relation between mechanical compliances and the metastatic potential of cancer cells has been suggested to be a promising progno...

palladium (ii) coordination complexes catalyze the reaction of alcohols with ketones to yield ethers. during the catalytic cycle, the alcohol adds selectively to the β-carbon (anti-markovnikov). in this work, mechanism and kinetics for the reaction of methanol with methyl vinyl ketone (mvk), being catalyzed by pd, has been theoretically investigated in detail. using quantum mechanical approach,...

the main objective of this study was to produce ldpe active films containing metallic nanoparticles (ag, zno and cuo) and to investigate their physical, mechanical and anti-microbial characteristics. three types of metallic nanoparticles at concentrations of 1% (w/w) were added to low density polyethylene (ldpe) and the films were prepared using melt extrusion technique. sem results indicated r...

To the Editor: After the emergence of pandemic (H1N1) 2009 virus, measures for its control were taken quickly (e.g., isolation of affected patients and use of gowns, gloves, and N95 respirators) when a clinical suspicion of pandemic infl uenza was established (1). One population group frequently exposed to this virus is health care staff. These circumstances prompted us to implement a screening...

natural rubber/fiber composites were prepared in a laboratory mixer using new and waste short nylon fiber by a one-step mixing process. fiber loading and bonding agent effects on the microstructure and mechanical properties of the composites were studied. the cure characteristics of composites were investigated by using rheometer. cure and scorching times of the composites decreased while maxim...

introduction: cholestasis is impairment of normal bile excretion into the duodenum and classified as mechanical and non mechanical cholestasis. mechanical cholestasis presents with increase in bile duct diameter or obstruction in bile duct in an ercp. cholestasis leads to different complications. one of these complications is mucosal peptic erosion leading to gastrointestinal bleeding, perforat...
