Verschillen tussen het Nederlandse EMDR-standaardprotocol en het originele protocol van Shapiro: Deel IV: Scherpstellen, desensitisatie en ‘Back to target’
No full textIn een serie artikelen (Hornsveld, Ten Broeke & de Jongh, 2017a, b, c) bespreken wij de belangrijkste aanpassingen in het Nederlandse EMDR-standaardprotocol ten opzichte van de originele versie van Shapiro. In deze bijdrage gaan we met name in op de onderdelen Scherpstellen en Desensitisatie (stap 2 en 3) van het protocol. Daarnaast wordt de huidige Nederlandse ‘back to target’ -procedure beschreven

Feature Contributions to ECG-based Heart-Failure Detection: Deep Learning vs. Statistical Analysis
No full textAssessing feature contributions to a specific diagnosis is commonly done by statistical analysis. In the context of heart failure (HF) diagnosis from the electrocardiogram (ECG), this work compares feature contributions assessed by deep learning with those obtained by statistical analysis. Data consists of ECG pairs (baseline and follow-up) from patients with a history of myocardial infarction. When the follow-up ECG was made, controls patients had remained stable, while cases patients had developed HF. The 42 features that characterized each ECG served as inputs of a deep-learning neural network (NN) created by our Repeated Structuring & Learning Procedure. Subject-specific feature ranking was obtained from the local-interpretable model-agnostic explanatory algorithm and processed to obtain feature relevances (FR). Additionally, 42 areas under the curve (AUC) by univariate statistical analysis were obtained. FR and AUC were compared by Pearson's correlation coefficient (p). After training, the NN had a 99% classification performance. FR ranged from 0.32 to 4.47; AUC ranged from 23% to 82%. Correlation analysis yielded no significant association between AUC and FR (ρ=0.18, P-value =0.25). Deep-learning and statistical-analysis feature contributions to HF detection were discordant. Further studies will investigate which of the two approaches better reflects clinical interpretation
Orientation of the α-Helixes of Apocytochrome c and Derived Fragments at Membrane Interfaces, As Studied by Circular Dichroism
No full textThe orientation of the different helical regions of the mitochondrial precursor protein apocytochrome c has been studied using circular dichroism on isolated fragments of this protein associated with oriented films composed of various phospholipids [de Jongh, H. J. Goormaghtigh, E. & Killian, J. A. (1994) Biochemistry (preceding article in this issue)]. Both the N and C terminus adopt helical structures in a membrane environment. The middle region can also be helical, but only in the presence of the N-terminal domain of the protein. In the presence of the unsaturated lipids dioleoylphosphatidylcholine and dioleoylphosphatidylglycerol, all three helices are found to have a preferred orientation perpendicular to the membrane normal, whereas in the presence of the saturated lipids dimyristoylphosphatidylcholine and dimyristoylphosphatidylglycerol, the terminal helices are preferentially oriented parallel to the membrane normal. In films composed of dioleoylphosphatidylserine, it is found that the N-terminal helix is oriented preferentially perpendicular, whereas the C-terminal helix is aligned more parallel to the membrane normal. The differences in preferred orientation between the terminal helices are demonstrated by molecular modeling of the helices at a water‒lipid interface. The results are discussed in light of the translocation of apocytochrome c over the outer mitochondrial membrane, an important step in the import process of this protein in mitochondria. © 1994, American Chemical Society.

Estudo espectrocópico por RMN de scutianinas
No full textTCC (graduação) - Universidade Federal de Santa Catarina, Centro de Ciências Físicas e Matemáticas, Curso de Química.No presente trabalho foram estabelecidas as estruturas da Scutianina C e do Scutianeno D, com a finalidade de esclarecer dúvidas, surgidas durante a revisão da literatura. A análise destes compostos por técnicas de RMN em uma e duas dimensões possibilitou obter, a partir de amostras puras cedidas pelo prof. Ademir Morel (DQ-UFSM), completar os dados de deslocamentos químicos de 1H e 13C. Além das respectivas estruturas foi determinada a estereoquímica relativa de alguns centros quirais do Scutianeno D e da Scutianina C

Magnetothermal properties of molecule-based materials
No full text16 pages, 14 figures.-- El pdf del artículo es la versión post-print.We critically review recent results obtained by studying the low-temperature specific heat of some of the most popular molecule-based materials. After introducing the experimental techniques and basic theoretical framework needed for heat capacity determination and understanding, we report on the magnetothermal properties of molecular antiferromagnetic wheels. For selected molecular high-spin clusters, particular emphasis is devoted to magnetic quantum tunnelling and coherence as well as collective phenomena as probed by heat capacity experiments. We discuss also the
possibilities of application of molecule-based materials for magneto-cooling at low temperatures and the limitations in other temperature ranges. Perspectives for future developments are mentioned as well.Special thanks go to J. C. Lasjaunias, P. Gandit, J. Chaussy and I. Sheikin (CNRS, Grenoble) and M. A. Novak who contributed much to the development of this field.

Structural And Superconducting Properties Of Labacacu3o7+δ System: A Neutron Diffraction Study
No full textThe results on structural aspects and superconductivity of LaBaCaCu3O7+δ (La:1113) are reported. Both X-ray and neutron diffraction studies have been carried out on this compound which reveal that this compound crystallizes in the tetragonal structure (space group P4/mmm). Detailed analysis of the neutron diffraction data reveals that the Ca, Ba and La atoms in this compound are intermixed at the nominal La and Ba sites. Nearly 46% of Ca occupy the usual La-site, while the remaining 54% occupies the Ba-site. Consequently, a corresponding amount of La substitutes at the Ba-site. The intermixing of Ca, Ba and La sites randomizes the chain site oxygens leading to a tetragonal structure for this compound despite an oxygen content close to 7. These occupancy refinements explain the tetragonal structure of the compound, despite having an oxygen content close to 7.04. The compound studied presently shows a sharp superconducting transition at about 68 K.31419397Oesterreider, H., Smith, M., (1987) Mater. Res.
