Each anatomical site respectively have their own proper water content of SC which reflects the status of skin health. Also, this anatomical region can be divided into relatively wet and dry area according to the degree of the water content of SC. In ...

The water content of stratum corneum (SC) has been reported to vary depending on the anatomical sites. Each anatomical site respectively have their own proper water content of SC which reflects the status of skin health. Also, this anatomical region can be divided into relatively wet and dry area according to the degree of the water content of SC. In this study, we tried to investigate time series trend of the water content. Skin hydration was measured on the different anatomical sites for the first four seconds using single frequency-susceptance measuring method. It is observed that the slope of the graph for the water content during the first four seconds is different depending on the anatomical sites and can be divided into two groups by the degree of the slope. These grouped areas are well aligned with traditional wet and dry area. It is presumed that the difference of the gradient could be caused by the thickness of SC. In this study, the different gradient of time series trend of water content of SC on different anatomical sites was found, and it could be conveniently used to distinguish the wet and dry area of the skin
Ebp1 is a member of the PA2G4 family protein and initially isolated as an ErB3 (an epidermal receptor tyrosine kinase) binding protein. Ebp1 inhibits cell growth and repress transcription of E2F-regulated cell cycle genes. Previously, we reported that Ebp1 protein interacted with RNA polymerase subunit PB1 of the influenza virus and disturbed in vitro RNA synthesis by influenza RNA polymerase. Recently we found that after influenza virus infection to the cell, Ebp1 expression is induced at 4 hours after viral infection. By using reverse genetics method, Ebp1 inhibits influenza virus replication. Ebp1 expression mechanism is very interesting because the expression of Ebp1 is earlier than that of virus proteins. In addition, in uninfection cell, Ebp1 is expressed from G1 to S phase in cell cycle-dependent manner. Therefore we study to identify the transcription factor of Ebp1 and understand the Ebp1 expression mechanism by influenza viral infection. Ebp1 promoter region was cloned into pTurboGFP. A pTurboGFP-Ebp1 promoter plasmid was mixed with nucleus extract form infection/uninfection cell. The binding proteins were eluted and analyzed by liquid chromatography-tandem mass spectrometry (LC-MS/MS). We identified several candidate proteins.
Introduction - The TASER®conducted electrical weapon (CEW) delivers electrical pulses that can temporarily incapacitate subjects. We analyzed the distribution of TASER CEW currents in tissues posterior to the sternum to understand the likelihood of triggering cardiac arrhythmias. We also assessed the electrical `shielding' effects of the sternum. Methods and Results - Finite element modeling (FEM) was used to approximate the current density and electric field strength in tissues around the sternum. We analyzed 2 CEW dart deployment scenarios: (a) both darts over the anterior aspect of the sternum; and (b) a CEW dart anterior to the sternum and the other over the abdomen. In both scenarios, the sternum provided significant attenuation of CEW currents. Particularly, both FEMs predicted that the residual electrical current or charge from CEWs would be insufficient to cause either cardiac capture or induction of ventricular fibrillation at locations where cardiac tissue would reside relative to the posterior aspect of the sternum. Conclusion - The sternum offers significant `shielding' effect and protects the tissues posterior to it against effects of electrical current flow from anteriorly- placed CEW electrodes.
Signal transduction pathways control cellular responses to stimuli, but it is unclear how molecular information is processed as a network. Large-scale collection and systematization of such data is likely to have a great impact on cell biology as complete genome sequencing has had on genetics. Cell signaling pathways interact with one another to form networks. Such networks are complex in their organization and exhibit emergent properties such as bistability and ultra sensitivity. Analysis of signaling networks requires a combination of experimental and theoretical approaches including the development and analysis of models. This work examines signaling networks that control the survival decision treated with combinations of the pro-death cytokine, tumor necrosis factor-a (TNF), and the pro-survival growth factors, epidermal growth factor (EGF) and insulin. A non linear model using Artificial Neural Network was proposed for cell survival/ death. With this we have made software which is used by doctors in doing chemotherapy without doing any experiments.
Everyday cells encounter various stimuli ranging from growth signals to bacterial infections to UV insult to death signals. They must somehow receive these signals, interpret them, integrate different stimuli, and generate the required output. They can do so by an intricate mechanism named intracellular signal transduction. There are various signal transduction pathways within a cell, each of which are designed for a particular stimulus, and all of which can crosstalk among themselves for the careful integration of all stimuli. In this report, only one of these pathways, the mitogen-activated protein kinase (MAPK) pathway has been simulated. This pathway is activated upon binding of growth factors to their respective cell surface-bound receptors. Activated receptors relay the incoming signal to the cell interior via a cascade of proteins, which are thought to be involved in both the amplification of the signal, and the specificity of the pathway. A generic MAPK pathway activated by the EGF (epidermal growth factor) and the effect of receptor overexpression has been studied, and consistent with experimental evidence, it is shown that the number of EGF receptors on the cell surface is a key factor in the response generated by the pathway.
This work presents a review of most used biomaterials in the field of tissue engineering with applications to epithelial tissue. The analysis has reviewed fifty different scientific articles published from 1997 to 2012. The information is classified according to the type as natural or synthetic biomaterials in epithelial tissue engineering, and according to its application as dermal, epidermal, or dermal-epidermal substitutes. The advantages and disadvantages of its implementation as in vitro or clinical applications are highlighted. As a result, natural materials are suitable in terms of biocompatibility with the receiver at the time of graft, but they have low mechanical resistance. Moreover, synthetic materials have shown high mechanical resistance but remain under investigation to develop more biocompatible products and easy removal processes. Within the study, it was found as a very promising area the use of nanomaterials and scaffold techniques for creating structures that support the tissue engineering.
Our work concern is to adequately mark products in the cigars industry using a laser engraver. The work show the possibility of marking flexible and delicate material without destroying the item itself. In this method, a marking image is accomplished with two axes high speed system that direct the laser energy across the target surface. The lens assembly focuses the laser energy to achieve the highest power density on the work surface while maintaining the focused spot travel on a flat plane. The laser can be regulated to different intensities and/or translation speeds during the marking process to achieve different levels of contrast within a particular design.
We report a model-based analysis of a recently proposed mechanism in Drosophila oogenesis (Peri et al., 1999; Sapir et al., 1998; Wasserman and Freeman, 1998). Our model describes the spatial organization and the dynamics of autocrine and paracrine signaling through the Drosophila Epidermal Growth Factor Receptor (EGFR) (Casci and Freeman, 1999; Nilson and Schupbach, 1999; Perrimon and Perkins, 1997; Schweitzer and Shilo, 1997). We use the model to estimate the relative spatial ranges and time scales of the relevant feedback loops, to interpret the phenotypic transitions in eggshell morphology, and to predict the effects of new genetic manipulations.
