    The aim of this review was to identify studies exploring neuroanatomy teaching tools and their impact in learning, as a basis towards the implementation of a neuroanatomy program in the context of a curricular reform in medical education

    Surface magnetization in non-doped ZnO nanostructures

    Full text link
    We have investigated the magnetic properties of non-doped ZnO nanostructures by using {\it ab initio} total energy calculations. Contrary to many proposals that ferromagnetism in non-doped semiconductors should be induced by intrinsic point defects, we show that ferromagnetism in nanostructured materials should be mediated by extended defects such as surfaces and grain boundaries. This kind of defects create delocalized, spin polarized states that should be able to warrant long-range magnetic interactions.Comment: 8 pages, 3 figure

    Specificity and performance evaluation of a novel RNA-FISH probe for the identification of Rhodotorula sp.

    To distinguish Rhodotorula sp., from other microorganisms that produce the same type of alterations on CH materials, proper identification methods must be applied. RNA-fluorescence and in situ hybridization (RNA-FISH) has the potential to specifically identify the target microorganism of interest in complex microbial communities (it is based on hybridization of fluorescently-labeled oligonucleotide probes targeting to specific regions of the ribosomal RNA). Thus, the aim of this study was to design a novel genus specific RNAFISH probe against Rhodotorula sp., and to evaluate its specificity and performance both in silico and experimentally. This will contribute for facilitating Rhodotorula sp., identification in degraded CH materials by RNA-FISH.This work was co-financed by FCT through PTDC/BBB-IMG/0046/2014 project and SFRH/BPD/100754/2014 grant and by ALT20-03-0246-FEDER-000004-ALENTEJO 2020 project

    Eight cycles of recurrent selection for resistance to angular leaf spot in common bean.

    The genetic progress (GP) was evaluated after eight cycles of recurrent selection for resistance to angular leafspot in common bean and indirect gain for yield and grain type. The base population (Cycle-0) was obtained from the diallelcross of seven lines with carioca grain and ten resistance sources. To obtain Cycle I, the most resistant S0 plants of Cycle 0were intercrossed. The same procedure was adopted in the subsequent cycles. GP for resistance to the pathogen was estimatedby the overall average of the progenies of each cycle in comparison with control Carioca MG and for productivity incomparison to the controls Carioca MG and Pérola. Lines of the first six cycles were used for grain type. No GP was detectedfor resistance to angular leaf spot. However, the indirect yield gain was 2.3% and 2.5% in the selection for grain type, withvalues similar to those obtained by direct selection for these traits

    Technical Report: Technique of Bladder Catheterization in Female Mice and Rats for Intravesical Instillation in Models of Bladder Cancer

    Get PDF
    Animal models offer a system that enables a better understanding of basic biological questions. Urinary bladder catheterization is a common procedure in models of female urothelial tumours and yet the technique does still need to be described further. The methods described in the existing literature do not outline how the procedure should be adapted for different research goals. In this report, we describe systematically catheterization of female mice and rats as well as analysing several anaesthetic protocols, which can be used to carry out this technical procedure

    Regressão linear para predição do estado nutricional de bananeiras tipo prata.

    Get PDF
    A avaliação do estado nutricional de bananeiras é fundamental para recomendação de adubação e manejo da cultura. Diversos métodos analíticos são utilizados, mas a segurança dos dados e a demora para a obtenção dos resultados dificulta a tomada de decisão que favorece o aparecimento de sintomas de deficiência e consequente queda de produtividade da lavoura
