Phase-based manganese enhanced MRI, a new methodology to enhance brain cytoarchitectural contrast and study manganese uptake

Rolf Gruetter, José Pedro Rebelo Ferreira Marques, Rajika Maddage

Purpose As the magnetic susceptibility induced frequency shift increases linearly with magnetic field strength, the present work evaluates manganese as a phase imaging contrast agent and investigates the dose dependence of brain enhancement in comparison t ...

A Viscosity-Dependent Affinity Sensor for Continous Monitoring of Glucose in Biological Fluids

Christophe Boss

For fifty years, tremendous efforts have been directed towards the development of glucose sensors for tight glycemic control of diabetic patients. Today, millions of diabetics test their blood glucose level daily, making glucose the most commonly tested an ...

Heterogeneous Chemistry of Cl2O and HOCl on Frozen Natural Sea Salt, Recrystallized Sea Salt, KCl and NaCl Solutions at 200 and 215 K

Michel Rossi, Pascal Pratte

The HOCl heterogeneous reaction on frozen natural (NSS) and recrystallized (RSS) sea salt KCl and NaCl solutions was studied using a low pressure flow reactor in order to measure the uptake coefficient gamma and products of reaction The HOCl sample used in ...

Force spectroscopy of barnase-barstar single molecule interaction

Giovanni Dietler, Mélanie Favre, Dmitry Klinov

Results of the single molecule force spectroscopy study of specific interactions between ribonuclease barnase and its inhibitor barstar are presented. Experimental data obtained for the force loading rate ranging 2-70 nN/s are well approximated by a single ...

Comparative study of human erythrocytes by digital holographic microscopy, confocal microscopy, and impedance volume analyzer

Pierre Magistretti, Christian Depeursinge, Benjamin Rappaz, Pierre Marquet

Red blood cell (RBC) parameters such as morphology, volume, refractive index, and hemoglobin content are of great importance for diagnostic purposes. Existing approaches require complicated calibration procedures and robust cell perturbation. As a result, ...

Calcium dynamics and vasomotion in arteries subject to isometric, isobaric, and isotonic conditions

Jean-Jacques Meister, Roger Sauser, Jean-Louis Bény, Michèle Koenigsberger, Dominique Seppey

In vitro, different techniques are used to study the smooth muscle cells' calcium dynamics and contraction/relaxation mechanisms on arteries. Most experimental studies use either an isometric or an isobaric setup. However, in vivo, a blood vessel is neithe ...

Water-soluble stimuli-responsive vesicles from peptide-based diblock copolymers

Harm-Anton Klok

Polypeptide secondary structure controls the dimensions of aggregates formed from a polybutadieneb-poly(L-glutamic acid) diblock copolymer after direct dissolution into water. The hydrodynamic radius (RH) of these aggregates (even at high NaCl concentratio ...

Brain lactate by magnetic resonance spectroscopy during fulminant hepatic failure in the dog

Rolf Gruetter

A noninvasive test is needed to assess the severity of encephalopathy during fulminant hepatic failure. This feasibility study was designed to compare a noninvasive test, brain lactate measurement by magnetic resonance spectroscopy, with intracranial press ...

Adhesion prevention with ancrod released via a tissue-adherent hydrogel

Jeffrey Alan Hubbell

The objective of this investigation was to evaluate the effect of ancrod, a fibrinogenolytic protease from Malayan pit viper venom, locally delivered through a photopolymerized biodegradable hydrogel in preventing postoperative adhesions. The experimental ...

Surface Characterization of Colloidal Silica Nanoparticles by Second Harmonic Scattering: Quantifying the Surface Potential and Interfacial Water Order

Sylvie Roke, Arianna Marchioro, Cornelis Ulrich Lütgebaucks, Marie Bischoff

The microscopic description of the interface of colloidal particles in solution is essential to understand and predict the stability of these systems, as well as their chemical and electrochemical reactivity. However, this description often relies on the u ...
