1. Efeitos de terpenos nas membranas de estrato córneo estudados por ressonância paramagnética eletrônica / Effects of terpenes on the stratum corneum membranes studied by electron paramagnetic resonance
The interaction of the skin penetration enhancers DL-menthol, -terpineol, 1,8-cineole and (+)-limonene with membranes of the uppermost skin layer, the stratum corneum (SC) and with multilamellar vesicles from 1,2-dipalmitoyl-sn-glycero-3-phosphaticylcholine (DPPC)is investigated by electron paramagnetic resonance (EPR) spectroscopy using spin-labeled

2. Estudo da evolução dinamica de nanofios de cobre e ouro / Study of dynamical evolution of cooper and gold
Metallic nanowires have been a subject of study for at least ½fteen years. The interest in these new materials is increasing continuously due to the possibility of using them as metallic contacts in electronic nanodevices. For example, between two tips of very thin nanowires, it is possible to insert small structures, such as carbon buckyballs or small orga

3. Emancipatory molecular ruptures: the potentiality of social work practice / Rupturas moleculares emancipatórias: a potencionalidade da prática do serviço social
This study aims at analyzing the potentiality of the Social Work practice to produce emancipatory molecular ruptures in the context of Qualification Programs for Municipal Councilors of Social Assistance in the State of Paraná. Based on Gramscis theoretical fundamentals we argue the necessity of qualification and strengthening of these social subjects throu

4. Atomistic understanding of kinetic pathways for single base-pair binding and unbinding in DNA
We combine free-energy calculations and molecular dynamics to elucidate a mechanism for DNA base-pair binding and unbinding in atomic detail. Specifically, transition-path sampling is used to overcome computational limitations associated with conventional techniques to harvest many trajectories for the flipping of a terminal cytosine in a 3-bp oligomer in ex

5. Kinetics of the Multistep Rupture of Fibrin ‘A-a’ Polymerization Interactions Measured Using Atomic Force Microscopy
Fibrin, the structural scaffold of blood clots, spontaneously polymerizes through the formation of ‘A-a’ knob-hole bonds. When subjected to external force, the dissociation of this bond is accompanied by two to four abrupt changes in molecular dimension observable as rupture events in a force curve. Herein, the configuration, molecular extension, and kin
