In spite of its low throughput, Patch-Clamp is the established method for intracellular measurements of the transmembrane potential. To address this problem, we have developed new biosensor-chips with micro-structured needle electrodes (MNEs). MNE-penetration of single cells growing on the MNE-tips leads to a situation comparable to the whole-cell mode in classical Patch Clamp. MNE-penetration ...

Electroporation is an increase of the cell membrane permeability due to the formation of aqueous pores in it when the cell is under the influence of an intense electric field . The formation of such pores in the membrane can be used to enhance the uptake of chemotherapeutic drugs into the cell in a cancer treatment known as electrochemotherapy . In some cases the direct experimental ...

Predictive simulations of biomass conversion processes will improve their technical performance and reduce economic uncertainty surrounding industrialization of biofuels production. The majority of present conversion simulations treat the biomass feedstock with simplifying assumptions that neglect important characteristics that are unique to biomass particles. These characteristics, including ...

A eletroquimioterapia é um tratamento de câncer que utiliza a combinação de agentes quimioterápicos e campos elétricos. A base teórica por trás dessa aplicação é a eletroporação. Esse fenômeno biológico consiste na abertura de poros na membrana celular devido à aplicação de pulsos elétricos. Este trabalho analisa o comportamento do campo elétrico gerado por pulsos elétricos aplicados em ...

Introduction: Bone tissue has a limited ability for regeneration; critically sized defects cannot self-heal and require medical intervention. Bone tissue engineering (TE) circumvents this issue by growing replacement bone tissue from the patient’s own cells inside scaffolds. TE scaffolds are porous constructs that act as a support structure during bone regeneration and helps cells attach and ...

A 1D-axisymmetric model was built to represent the drying of a single d’Ente plum to d’Agen prune. Underlying assumptions of the model were those of Di Matteo et al. 2003. Sorption isotherms of plum come from Tsami et al, 1990 and equation structure of apparent water diffusion coefficients from Sabarez, 2001. External transfer coefficients were adjusted by direct measurements. The parameters of ...

In this paper, we present a mathematical model of contractile elastic solids meant to simulate various districts of the cardiovascular system, and based on the concepts of active deformation and embedded muscle fibres. Specifically, here we deal with the modeling of the gross mechanics of the Left Ventricle (LV) which is strictly related to its pump function. As is well known, the effectiveness ...

The modeling of light propagation through multiple layers of biological tissue are assessed & compared to the theoretical predictions by Perelman at al. [94 & 95] of the most-favorable-path (MFP). The MFP on which photons will be found can be obtained from the path of the net flux propagation using the diffusion equation. The diffusion equation is valid when studying diffuse light propagation, ...

This paper presents a numerical study of the deposition of submicron charged spherical particles caused by convection, Brownian and turbulent diffusion in a pipe with a smooth wall and with a cartilaginous ring wall structure (see figure). The model is supposed to describe deposition of charged particles in generation 0 (trachea) of the human lung.The problem is defined by solving the fluid flow ...

MRI offers many advantages over other modalities and its lack of ionizing radiation is important for children, but can be limited by the radio-frequency (RF) coils available. This work calculates Specific Absorption Rate (SAR) and homogeneity of the RF transmit field (B1+) when imaging infants in adult coils. Two birdcage-type coils were loaded by a tissue model and their B1+ homogeneities ...
