Lipid bilayer pre-transition as the beginning of the melting process.

- K. Riske, R. Barroso, C. C. Vequi-Suplicy, R. Germano, V. Henriques, M. Lamy
- Chemistry, Medicine
- Biochimica et biophysica acta
- 1 May 2009

We investigate the bilayer pre-transition exhibited by some lipids at temperatures below their main phase transition, and which is generally associated to the formation of periodic ripples in the… Expand

Liquid polymorphism, density anomaly and H-bond disruption in associating lattice gases

- A. Balladares, V. Henriques, M. Barbosa
- Chemistry, Physics
- 21 September 2006

We have investigated the effects of either distorting hydrogen bonds or removing proton degeneracy on the thermodynamic properties of a minimal model for associating liquids. The presence of two… Expand

Monte Carlo simulation of a lattice model for micelle formation

- A. Bernardes, V. Henriques, P. M. Bisch
- Chemistry
- 1 July 1994

We have investigated the aggregation into micelles of nonionic amphiphiles in water through Monte Carlo simulations of a very simple model system. Amphiphiles and water are modeled, respectively, as… Expand

Ionization and structural changes of the DMPG vesicle along its anomalous gel-fluid phase transition: a study with different lipid concentrations.

- R. Barroso, K. Riske, V. Henriques, M. Lamy
- Chemistry, Medicine
- Langmuir : the ACS journal of surfaces and…
- 29 July 2010

Dispersions of saturated anionic phospholipid dimyristoyl phosphatidylglycerol (DMPG) have been extensively studied regarding their peculiar thermostructural behavior. At low ionic strength, the… Expand

Liquid polymorphism and density anomaly in a lattice gas model.

- V. Henriques, M. Barbosa
- Physics, Medicine
- Physical review. E, Statistical, nonlinear, and…
- 29 July 2004

We present a simple model for an associating liquid in which polymorphism and density anomaly are connected. Our model combines a two dimensional lattice gas with particles interacting through a soft… Expand

Plasma Catecholamines during an Ultrarapid Heroin Detoxification

- T. Macedo, J. Relvas, +11 authors L. Vale
- Medicine
- Annals of the New York Academy of Sciences
- 1 September 2000

The adrenergic system has long been known to be activated in a situation of stress and thus during opiate withdrawal. A method for detoxification that decreases the stimulation of the sympathetic… Expand

Liquid polymorphism and density anomaly in a three-dimensional associating lattice gas.

- M. Girardi, A. Balladares, V. Henriques, M. Barbosa
- Chemistry, Physics
- The Journal of chemical physics
- 9 December 2006

The authors investigate the phase diagram of a three-dimensional associating lattice gas (ALG) model. This model combines orientational icelike interactions and "van der Waals" that might be… Expand

Liquid polymorphism, order-disorder transitions and anomalous behavior: A Monte Carlo study of the Bell-Lavis model for water.

- C. E. Fiore, M. Szortyka, M. Barbosa, V. Henriques
- Chemistry, Medicine
- The Journal of chemical physics
- 10 July 2009

The Bell-Lavis model for liquid water is investigated through numerical simulations. The lattice-gas model on a triangular lattice presents orientational states and is known to present a highly… Expand

Frustration and anomalous behavior in the Bell-Lavis model of liquid water.

- M. A. Barbosa, V. Henriques
- Physics, Medicine
- Physical review. E, Statistical, nonlinear, and…
- 19 May 2008

We have reconsidered the Bell-Lavis model of liquid water and investigated its relation to its isotropic version, the antiferromagnetic Blume-Emery-Griffiths model on the triangular lattice. Our… Expand
