Studying natural structural protein fibers by solid‐state nuclear magnetic resonance
Authors: Arnold Alexandre A. , Marcotte Isabelle 
Published: January 2009

AbstractAs a consequence of evolutionary pressure, various organisms have developed structural fibers displaying a range of exceptional mechanical properties adapted specifically to their functions. An understanding of these properties at the molecular level requires a detailed description of local structure, orientation with respect to the fiber and size of constitutive units, and dynamics on various timescales. The size and lack of long‐range order in these protein systems constitute an important challenge to classical structural techniques such as high‐resolution NMR and X‐ray diffraction. Solid‐state NMR overcomes these constraints and is uniquely suited to the study of these inherently disordered systems. Solid‐state NMR experiments developed or applied to determine structure, orientation, and dynamics of these complex proteins will be reviewed and illustrated through examples of their applications to fibers such as spider and silkworm silks, collagen, elastin, and keratin. © 2009 Wiley Periodicals, Inc.

Published: January 2009

AbstractBACKGROUND:Prognostic indices for recurrence‐free interval in patients with parotid carcinoma were developed and validated in a nationwide database. International validation would increase generalizability.METHODS:In a Belgian‐German database that contained 237 consecutive patients with parotid carcinoma, a pretreatment prognostic index (PS1) and a post‐treatment prognostic index (PS2) were validated by calculating both indices for each patient, comparing coefficients, constructing survival curves, calculating the concordance measure C, and performing Wald tests for scale and weight optimization of included variables and for the possible inclusion of new variables.RESULTS:Sixty‐nine percent of patients (standard error, 5%) were disease free at 5 years. The defined cutoff points for PS1 resulted in 5‐year disease‐free rates from 94% (PS1 = 1) to 42% (PS1 = 4), and the cutoff points for PS2 resulted in 5‐year disease‐free rates from 93% (PS2 = 1) to 40% (PS2 = 4). Concordance measure C was good with 0.74 for both PS1 and PS2. Neither index could be improved statistically using this international database. There was some evidence that additional inclusion of the variable ‘number of positive lymph nodes in the neck dissection specimen’ could enhance the prognostic power of PS2.CONCLUSIONS:The prognostic indices performed adequately in this validation sample. Prospective generalized use seems to be well supported. Cancer 2009. © 2009 American Cancer Society.
Cancer surveillance behaviors and psychosocial factors among long‐term survivors of breast cancer
Authors: Katz Mira L. , Donohue Kathleen A. , Alfano Catherine M. , Day Jeannette M. , Herndon James E. , Paskett Electra D. 
Published: January 2009

AbstractBACKGROUND:Little is known about cancer surveillance (mammography, clinical breast examination, and pelvic examination) behaviors in long‐term (9‐16 years) breast cancer survivors. This report describes the relation of these behaviors to demographic and clinical characteristics, psychological symptoms, body satisfaction, and social support.METHODS:Survivors who had participated in Cancer and Leukemia Group B treatment Trial 8541 completed a survey that included questions on breast cancer surveillance and pelvic examination, psychological well being, body satisfaction, and social support.RESULTS:The participation rate was 78% and included 245 breast cancer survivors. Survivors (n = 107; 44%) reported completing breast cancer surveillance (mammography and clinical breast examination) and completing pelvic examination (n = 162; 68%) within recommended guidelines. There were no significant associations between breast cancer surveillance and breast cancer anxiety, depression, stressful life events, body satisfaction, social support, or demographic characteristics. Survivors within recommended guidelines for pelvic examinations were younger (P = .05), married (P = .003), had health insurance (P = .004), and had lower depression scores (P = .005) than survivors who underused or overused pelvic examination. In addition, survivors within recommended pelvic examination guidelines had significantly lower levels of breast cancer anxiety (P = .03) compared with survivors who underused pelvic examination.CONCLUSIONS:Many long‐term breast cancer survivors were not within recommended cancer surveillance guidelines. Private health insurance was associated with following recommendations for pelvic examinations, although such a relation did not exist for breast cancer surveillance. The results of this study have implications for the development of educational programs to improve cancer surveillance among the growing population of long‐term breast cancer survivors.

Identification and localization of myosin superfamily members in fish retina and retinal pigmented epithelium
Authors: Lin‐Jones Jennifer , Sohlberg Lorraine , Dosé Andréa , Breckler Jennifer , Hillman David W. , Burnside Beth 
Published: January 2009

AbstractMyosins are cytoskeletal motors critical for generating the forces necessary for establishing cell structure and mediating actin‐dependent cell motility. In each cell type a multitude of myosins are expressed, each myosin contributing to aspects of morphogenesis, transport, or motility occurring in that cell type. To examine the roles of myosins in individual retinal cell types, we first used polymerase chain reaction (PCR) screening to identify myosins expressed in retina and retinal pigmented epithelium (RPE), followed by immunohistochemistry to examine the cellular and subcellular localizations of seven of these expressed myosins. In the myosin PCR screen of cDNA from striped bass retina and striped bass RPE, we amplified 17 distinct myosins from eight myosin classes from retinal cDNA and 11 distinct myosins from seven myosin classes from RPE cDNA. By using antibodies specific for myosins IIA, IIB, IIIA, IIIB, VI, VIIA, and IXB, we examined the localization patterns of these myosins in retinas and RPE of fish, and in isolated inner/outer segment fragments of green sunfish photoreceptors. Each of the myosins exhibited unique expression patterns in fish retina. Individual cell types expressed multiple myosin family members, some of which colocalized within a particular cell type. Because much is known about the functions and properties of these myosins from studies in other systems, their cellular and subcellular localization patterns in the retina help us understand which roles they might play in the vertebrate retina and RPE.

Ultrafast Photoinduced Processes in Alizarin‐Sensitized Metal Oxide Mesoporous Films
Authors: Dworak Lars , Matylitsky Victor V. , Wachtveitl Josef 
Published: January 2009

AbstractClose to the edge: Photoexcitation of alizarin coupled to the surface of mesoporous TiO2 films leads to ultrafast electron transfer to the TiO2 conduction band (see picture). Complex kinetics after photoexcitation depend on the excitation energy, and indicate a position of the alizarin excited state close to the TiO2 conduction band edge, where the density of acceptor states is reduced.magnified imageThe photoinduced dynamics in Al2O3 and TiO2 mesoporous films sensitized by the strongly coupled alizarin dye is investigated by femtosecond transient absorption spectroscopy in the spectral range from UV to mid‐IR. Alizarin/Al2O3 acts as a nonreactive reference system, in which no electron transfer is observed. For comparison, the photoexcitation of the alizarin dye coupled to the surface of TiO2 films leads to ultrafast electron transfer from the dye to the TiO2 conduction band on the sub‐100‐fs timescale. We observe a fast relaxation of the alizarin excited state as well as a fast recombination of injected electrons with the alizarin cation on the picosecond timescale, which gives rise to very complex kinetics at short delay times. The infrared measurements clearly indicate that trapping of injected electrons is the main mechanism responsible for the observed long‐lived charge separation in TiO2 mesoporous films. The experimental findings can be explained by a position of the dye excited state close to the conduction band edge.
Ab initio Study of the Interactions between CO2 and N‐Containing Organic Heterocycles
Authors: Vogiatzis Konstantinos D. , Mavrandonakis Andreas , Klopper Wim , Froudakis George E. 
Published: January 2009

AbstractIn the garden of dispersion: High‐accuracy ab initio calculations are performed to determine the nature of the interactions and the most favorable geometries between CO2 and heteroaromatic molecules containing nitrogen (see figure). Dispersion forces play a key role in the stabilization of the dimer, because correlation effects represent about 50 % of the total interaction energy.magnified imageThe interactions between carbon dioxide and organic heterocyclic molecules containing nitrogen are studied by using high‐accuracy ab initio methods. Various adsorption positions are examined for pyridine. The preferred configuration is an in‐plane configuration. An electron donor–electron acceptor (EDA) mechanism between the carbon of CO2 and the nitrogen of the heterocycle and weak hydrogen bonds stabilize the complex, with important contributions from dispersion and induction forces. Quantitative results of the binding energy of CO2 to pyridine (C5H5N), pyrimidine, pyridazine, and pyrazine (C4H4N2), triazine (C3H3N3), imidazole (C3H4N2), tetrazole (CH2N4), purine (C5H4N4), imidazopyridine (C6H5N3), adenine (C5H5N5), and imidazopyridamine (C6H6N4) for the in‐plane configuration are presented. For purine, three different binding sites are examined. An approximate coupled‐cluster model including single and double excitations with a perturbative estimation of triple excitations (CCSD(T)) is used for benchmark calculations. The CCSD(T) basis‐set limit is approximated from explicitly correlated second‐order Møller–Plesset (MP2‐F12) calculations in the aug‐cc‐pVTZ basis in conjunction with contributions from single, double, and triple excitations calculated at the CCSD(T)/6‐311++G** level of theory. Extrapolations to the MP2 basis‐set limit coincide with the MP2‐F12 calculations. The results are interpreted in terms of electrostatic potential maps and electron density redistribution plots. The effectiveness of density functional theory with the empirical dispersion correction of Grimme (DFT‐D) is also examined.
Preparation of Highly Luminescent CdTe/CdS Core/Shell Quantum Dots

Published: January 2009

AbstractA good balance: Oil‐soluble CdTe/CdS core/shell quantum dots (QDs) that emit in the visible and near‐infrared spectral regions with quantum yields up to 92 % (see figure) are prepared by balancing the coordinating capacity and the activation effect of selected surfactants.magnified imageAn effective shell‐coating route is developed for covering oil‐soluble CdTe quantum dots (QDs), which usually tend to aggregate during the heating‐up process involved in shell formation. The new route is based on balancing the coordinating capacity and the activation effect of selected surfactants. The thus obtained highly luminescent CdTe/CdS core/shell QDs exhibit photoluminescence quantum yields as high as 92 %—among the best results obtained so far for luminescent semiconductor nanocrystals. By changing the size of the CdTe core, or the thickness of the CdS shell, the emission colors of the obtained core/shell nanocrystals can be tuned between the visible and near‐infrared regions of the spectrum following an identical procedure.
