Recombinase technology: applications and possibilities

The use of recombinases for genomic engineering is no longer a new technology. In fact, this technology has entered its third decade since the initial discovery that recombinases function in heterologous systems (Sauer in Mol Cell Biol 7(6):2087–2096, 1987). The random insertion of a transgene into a plant genome by traditional methods generates unpredictable expression patterns. This feature of transgenesis makes screening for functional lines with predictable expression labor intensive and time consuming. Furthermore, an antibiotic resistance gene is often left in the final product and the potential escape of such resistance markers into the environment and their potential consumption raises consumer concern. The use of site-specific recombination technology in plant genome manipulation has been demonstrated to effectively resolve complex transgene insertions to single copy, remove unwanted DNA, and precisely insert DNA into known genomic target sites. Recombinases have also been demonstrated capable of site-specific recombination within non-nuclear targets, such as the plastid genome of tobacco. Here, we review multiple uses of site-specific recombination and their application toward plant genomic engineering. We also provide alternative strategies for the combined use of multiple site-specific recombinase systems for genome engineering to precisely insert transgenes into a pre-determined locus, and removal of unwanted selectable marker genes

El desarrollo de la creatividad en los niños y niñas de la primera infancia a través del fomento de las artes plásticas en el centro de desarrollo infantil guachené

La idea de realizar este proyecto de investigación para fomentar la creatividad en los niños y niñas de 4 a 5 años de edad; emerge en una problemática que se observó en el entorno escolar y que permitió resaltar la necesidad de crear espacios lúdicos que potencialicen su creatividad a través de la utilización de las expresiones artísticas dentro y fuera del aula de clases. Se deben proponer espacios educativos enriquecidos donde la clase de expresión plástica permita que los infantes sean espontáneos, libres y muy imaginativos; ya que por sí sola la expresión artística es un proceso que exige que el docente sea un guía, observe y estimule a los educandos para que ellos se sientan protagonistas en el desarrollo de la actividad y así dejen plasmado en cada trabajo su estilo propio. La intencionalidad pedagógica, los materiales de trabajo y los espacios donde se realizan las actividades con los niños y niñas, hacen parte de la planeación que debe realizar la docente en su sistematización de la clase, pues, el propósito del MEN es el “de enseñar a pensar” preparar a los alumnos para el futuro, que puedan resolver problemas con eficacia y disfrutar de toda una vida de aprendizaje y para ello, crea los referentes técnicos de la primera infancia como herramienta base que se utiliza para la planeación de las actividades pedagógicas. Para finalizar, se resalta la importancia del desarrollo de la creatividad durante el desarrollo infantil. Un niño creativo es un niño con una personalidad crítica, que le permite participar activamente en los diferentes aspectos de su entorno social-cultura

A Theory of Episodic Memory for Case-based Reasoning and its Implementation

This thesis makes several contributions to the study of Case-based Reasoning. It presents * a comprehensive description of the foundations of the subject in Knowledge Representation, Machine Learning and Cognitive Science, * A theory of learning for Case-based Reasoning * and it provides a demonstration of this theory by presenting an extensive implementation of a case-based system for Information Retrieval. In the first part of this thesis, research is presented on the foundations of Case-based Reasoning. It relates recent work in Artificial Intelligence to earlier and still developing ideas on the nature of concepts and categories. This part also presents research into the nature of learning in Case-based Reasoning. A review of Schank's Theory of Dynamic Memory is presented and a new Theory of the Acquisition of Episodic Memory is developed. The second part of the thesis is concerned with the practical application of Case-based Reasoning. This research demonstrates how the cognitive processes involved in concept formation and the new Theory of Acquisition of Episodic Memory can be put to practical use. A complete information retrieval system is presented. This system, in addition to being an implementation of the ideas presented in the first part of the thesis, is also intended as a substantive advance in the field of Information Science. It shows how Case-based Reasoning can be used to improve query formulation by exploiting information about the contexts in which queries arise. Particular attention is paid to the problem of recognition of similarity, which is an issue of concern to both Case-based Reasoning and Information Retrieval

Self pregnancy testing in an urban family planning clinic: promising results for a new approach to contraceptive follow-up

Immediate initiation of depo-medroxyprogesterone acetate (DMPA) increases continuation and decreases pregnancies compared to conventional (next menstrual period) initiation. A drawback is the need to return in 4 weeks for a repeat pregnancy test to identify any pregnancy that was too early to diagnose on the day of injection. If women can perform home pregnancy tests (HPTs) to detect human chorionic gonadotropin (hCG) in urine, the need for this follow-up visit may be eliminated. This study assesses whether women can perform their own HPT. This is a single-visit observational trial of an HPT kit. Subjects recruited from a waiting room in an urban family planning clinic received an HPT kit with standard instructions to use immediately. Subjects and a research assistant each interpreted the test. Their results were then compared to a standard cassette type test for detection of hCG performed by clinic staff. kappa was calculated to assess the level of agreement. Three hundred ten subjects enrolled. They were young (mean age, 25.2 years), mostly Hispanic (91%) women. A change in the font and explicitness of the instructions decreased the incidence of invalid tests from 12.7% to 4.8%. The subject and research assistant's interpretation of the test had a high level of agreement, kappa=0.95 [95% confidence interval (CI), 0.92-0.99]. There was also a high level of agreement between the subjects' results and the standard test, kappa=0.88 (95% CI, 0.82-0.95). Women presenting for pregnancy testing at an urban clinic are able to perform HPTs with a high level of accuracy. The appearance of the instructions influenced the incidence of false-negative and invalid tests. Home pregnancy tests may be useful in follow-up protocols when immediate initiation of DMPA is employed

Space requirement of a prefabricated bar on two interforaminal implants: a prospective clinical study

OBJECTIVES This clinical study measured the dimensional changes of existing lower complete dentures due to the integration of a prefabricated implant bar. Additionally, the impact of this dimensional change on patient satisfaction and oral function was analyzed. METHODS Twenty edentulous patients (10 men/10 women; aged 65.9 ± 11.8 years) received two interforaminal implants. Subsequent to surgery, a chair side adapted, prefabricated bar (SFI Bar(®), C+M, Biel, Switzerland) was inserted, and the matrix was polymerized into the existing lower denture. The change of the denture's lingual dimension was recorded by means of a bicolored, silicone denture duplicate that was sectioned in the oro-vestibular direction in the regions of the symphysis (S) and the implants (I-left, I-right). On the sections, the dimensional increase was measured using a light microscope. Six months after bar insertion, patients answered a standardized questionnaire. RESULTS All dentures exhibited increased lingual volume, more extensively at S than at I (P = 0.001). At S, the median diagonal size of the denture was doubled (+4.33 mm), and at I, the median increase was 50% (I-left/-right = +2.66/+2.62 mm). The original denture size influenced the volume increase (P = 0.024): smaller dentures led to a larger increase. The amount of denture increase did not have negative impact on either self-perceived oral function or patient satisfaction. Approximately, 95% of the patients were satisfied with the treatment results. CONCLUSIONS The lingual size of a lower denture was enlarged by the integration of a prefabricated bar without any negative side effects. Thus, this attachment system is suitable to convert an existing full denture into an implant-supported overdenture
