Experimental approaches for the generation of induced pluripotent stem cells
Cesar A Sommer, Gustavo Mostoslavsky
Stem Cell Research & Therapy , 2010, DOI: 10.1186/scrt26
Abstract: The potential use of embryonic stem cells (ESCs) for cell replacement therapies is limited by ethical concerns and the technical hurdles associated with their isolation from human embryos. In addition, as the genetic identity of the donor egg from which the ESCs are derived most likely will differ from that of potential recipients, patients who receive ESC-derived cells or tissues may face the same complications that result from organ transplantation (for example, immunorejection, graft-versus-host disease, and need for immunosuppression). To circumvent these obstacles, considerable effort has been invested in attempting to derive ESC-like cells by reprogramming somatic cells to an embryonic state. Although exciting results have been achieved by means of somatic cell nuclear transfer, cell fusion, and culture-induced reprogramming [1], these procedures are technically demanding and inefficient and therefore unlikely to become a common approach for producing patient-specific pluripotent cells. In 2006, a major breakthrough was reported in Japan by Takahashi and Yamanaka, who described the generation of induced pluripotent stem cells (iPSCs) from mouse fibroblasts via over expression of defined transcription factors [2]. Shortly afterwards, the original experimental protocol was replicated and optimized by several laboratories, confirming that iPSCs share the gene expression profile, epigenetic modifications, and proliferation rates as well as the pluripotency of ESCs [3]. Importantly, iPSCs were subsequently derived from adult human fibroblasts, providing a feasible way of producing tailor-made pluripotent cells with clinical translational potential [4-7].The fact that iPSCs can be derived from easily accessible somatic cells, such as skin fibroblasts or keratinocytes [8], has opened up new horizons in the field of regenerative medicine [9]. Jaenisch and colleagues [10,11] showed - as proof of principle of the therapeutic potential of iPSCs - the rescue of sickle cel
The Influence of Carl Rogers’ Humanism on the Development of Positive Attitudes in Medical Students  [PDF]

Abstract: The medical school has the purpose of comprehensively training competent undergraduate students by developing their knowledge, skills and attitudes. However, the best way to teach them attitudes has not yet been established, and many schools delegate this mission to humanistic disciplines. There are few reports regarding the influence of humanism on the development of attitudes, fact that increases the difficulty in integrating humanistic themes to teaching purposes in health. The current paper analyzes the influence of Carl Rogers’ humanistic conception on the attitudes of a sample comprising medical school students from the Federal University of Santa Maria, under five dimensions (knowledge, ambience, ethical, social and belief). The results showed that the Rogerian intervention significantly influenced the development of positive attitudes within the “belief” dimension. There was increase in the attitude score in all dimensions, showing positive tendency between the beginning and end of the study. The students whose profile showed positive attitudes in all dimensions were from the female gender, whose fathers and mothers had higher education degree. These students also used books and journals as complementary source of studies and dedicated a time equal to or greater than six hours per week to study. It can be concluded that Carl Rogers’ humanistic principles may be properly used without causing discomfort or threat to both the students and the teacher. The student-centered teaching is not a method or a theory, but a style in the teacher-student relationship, in which the formative aspect outweighs the informative one.
Los principios de la teoría de la evolución biológica y su utilidad para la administración de empresas
Berumen, Sergio A;Palacios Sommer, Octavio;
Contaduría y administración , 2007,
Abstract: in this article it is stated that the most demonstrated statements of the theory of biological evolution might be extremely useful for the analysis of business administration. evolutionary theory focuses in the use of analogies or biology concepts to analyze the behavior of institutions and social systems. for this focus, the signals that companies receive from the economical system are of three types: i) the technological opportunities and the benefits expected, which are closely related to them; ii) the current behavior and the expected one from the demand from its products and other products; and iii) the changes in costs, prices, quantities, and rentabilities in the markets in which they operate, and in some others.

Renormalization approach to many-particle systems
K. W. Becker,A. Huebsch,T. Sommer
Physics , 2002, DOI: 10.1103/PhysRevB.66.235115
Abstract: This paper presents a renormalization approach to many-particle systems. By starting from a bare Hamiltonian ${\cal H}= {\cal H}_0 +{\cal H}_1$ with an unperturbed part ${\cal H}_0$ and a perturbation ${\cal H}_1$,we define an effective Hamiltonian which has a band-diagonal shape with respect to the eigenbasis of ${\cal H}_0$. This means that all transition matrix elements are suppressed which have energy differences larger than a given cutoff $\lambda$ that is smaller than the cutoff $\Lambda$ of the original Hamiltonian. This property resembles a recent flow equation approach on the basis of continuous unitary transformations. For demonstration of the method we discuss an exact solvable model, as well as the Anderson-lattice model where the well-known quasiparticle behavior of heavy fermions is derived.
The B*Bpi Coupling in the Static Limit
J. Bulava,M. A. Donnellan,Rainer Sommer
Physics , 2010,
Abstract: We study an accurate method for the lattice calculation of the B*Bpi Coupling in the static limit, paying particular attention to excited state contamination. As this coupling is a parameter of the heavy meson chiral Lagrangian, it is useful for constraining the chiral behaviour of various observables in B-physics. We present a precise study of the continuum limit in the quenched approximation and preliminary results with 2 flavours of improved Wilson quarks (using CLS lattices) for pion masses down to around 250 MeV. With dynamical quarks both the lattice spacing and the light quark mass dependences are found to be very weak. We can quote g = 0.51(2) for the continuum value in the chiral limit, where the error will be reduced when a more complete analysis has been performed.
Fruiting Body Production and Aroma Profile Analysis of Agrocybe aegerita Cultivated on Different Substrates  [PDF]
Vanessa Kleofas, Laura Sommer, Marco A. Fraatz, Holger Zorn, Martin Rühl
Natural Resources (NR) , 2014, DOI: 10.4236/nr.2014.56022

The industrial cultivated basidiomycete Agrocybe aegerita, also known as “Pioppino” in Italy or “Samthaube” in Germany, is a high quality mushroom with a delicious aroma. Cultivation of A. aegerita on wheat straw supplemented with different residues of the food industry showed the highest yields in fruiting body production with a biological efficiency of 36% when black tea pomace was added. The addition of other substrates resulted in biological efficiencies of 23% to 33%. Besides the mushroom yields, the number and size of fruiting bodies harvested on the different substrates were determined. A comparison of the aroma profiles of A. aegerita grown on wheat straw and on wheat straw supplemented with black tea by means of GC/MS/MS/O is presented.

Polimorfismo no gene GH1-PstI associado a características corporais de linhagens de tilápia-do-nilo

Abstract: the objective of this study was to determine the association polymorphisms in growth hormone gene gh1 with the corporal characteristics in nile tilapia (oreochromis niloticus) strains. fragments of the caudal fin were collected from 5-month old fishes for analysis by polymerase chain reaction - restriction fragment length polymorphism (pcr-rflp). the following measurements were accomplished: total length, standard length, height, width, and head length. a fragment with 652 bp of the gh1 gene was amplified with subsequent restriction with the enzyme psti. for the analysis of the association of the molecular marker with the quantitative traits the sas glm procedure was used. the polymorphism described for the intron 1 of the gh1 gene of nile tilapia had significant correlation with total length, standard length, and body height and width. it was found that the genotype psti+/- is associated with better performance regardless of strain. such association may be due to direct effect of the gh gene own regulation.
