AbstractBACKGROUND:To the authors' knowledge, the indications for adjuvant treatment in acinic cell carcinoma (AciCC) of the parotid gland have not been elucidated to date. The aim of the current study was to determine patterns of failure and adverse prognostic features.METHODS:Between March of 1989 and August of 2006, 35 patients underwent surgery at Memorial Sloan‐Kettering Cancer Center for AciCC of the parotid gland and had their clinical and pathologic features retrospectively analyzed at the primary site. All cases were reviewed by 2 head and neck pathologists. Five‐year estimates of survival outcomes were performed, followed by univariate analysis of potential prognostic features.RESULTS:The T classifications were as follows: T1 in 46% of patients, T2 in 23% of patients, T3 in 18% of patients, and T4 in 9% of patients. Three patients had cervical lymph node involvement. All patients underwent surgery as their primary treatment. Approximately 63% of patients (n = 22) received radiation treatment. The median follow‐up time for surviving patients was 59.9 months. Five‐year estimates of disease‐free survival (DFS), overall survival (OS), and local control were 85%, 90%, and 90%, respectively. Of the clinical variables tested, clinical extracapsular extension (ECE), facial nerve sacrifice, and lymph node involvement were found to be significantly associated with a detriment in DFS and OS (P < .05). Positive surgical margins, histologic ECE, >2 mitoses per 10 high‐power fields (HPF), atypical mitosis, vascular invasion, perineural invasion, pleomorphism, and necrosis were associated with adverse DFS (P < .05). All of these variables except for vascular invasion (P = .377) and perineural invasion (P = .07) were associated with OS. If high‐grade tumors were defined on the basis of high mitotic activity (>2 mitoses/10 HPF) and/or tumor necrosis, high‐grade carcinomas had a significantly lower DFS and OS (P = .001).CONCLUSIONS:AciCC had a low treatment failure rate, and a large number of patients could be considered candidates for surgery only. A histologic grading system was devised to help stratify patients for adjuvant treatment. Cancer 2009. © 2009 American Cancer Society.
Higher expression of chemokine receptor CXCR7 is linked to early and metastatic recurrence in pathological stage I nonsmall cell lung cancer

Published: March 2009

AbstractBACKGROUND:The authors elucidated particular chemokine receptors that are expressed on lung cancer cells, as well as the clinical significance of the expression of these chemokine receptors in completely resected nonsmall cell lung cancer (NSCLC).METHODS:The authors examined gene expression of chemokine receptors (CCR1‐11, CXCR1‐7, XCR1, and CX3CR1) in 11 cell lines of lung cancer, and gene expression of CXCR3, CXCR4, and CXCR7 (CXCR3/4/7) in surgical specimens of 127 patients who underwent complete resection for their NSCLC between May 2001 and December 2002, using quantitative real‐time reverse transcriptase–polymerase chain reaction (PCR). Mutation detection analysis of the EGFR genes using the PCR single‐strand conformational polymorphism method was evaluated in patients with pathological (p‐) stage I adenocarcinoma.RESULTS:Substantial expression of CXCR3/4/7 mRNA was observed in all NSCLC cell lines examined. In p‐stage I NSCLC, CXCR4 and CXCR7 expression values in patients with postoperative metastatic recurrence (Rec‐Distant) were significantly higher than in those without recurrences (P = .003 and P = .007, respectively). In addition, the 5‐year disease‐free survival (DFS) rate of high CXCR7‐expressing patients (63.2%) was significantly lower than that of low CXCR7‐expressing patients (84.8%) (P = .033). The EGFR mutation was significantly more frequent in patients with higher CXCR7 expression (14 of 21 patients) than in those with lower CXCR7 expression (12 of 32 patients) (P = .038). A multivariate analysis confirmed that high CXCR7 expression was an independent and significant factor predicting a poor DFS in p‐stage I NSCLC patients (P = .041).CONCLUSIONS:Higher expression of CXCR7 is associated with Rec‐Distant and poor DFS in patients with p‐stage I NSCLC.

The effect of modafinil on cognitive function in breast cancer survivors
Authors: Kohli Sadhna , Fisher Susan G. , Tra Yolande , Adams M. Jacob , Mapstone Mark E. , Wesnes Keith A. , Roscoe Joseph A. , Morrow Gary R. 
Published: March 2009

AbstractBACKGROUND:The authors conducted a randomized clinical trial examining the effects of modafinil in reducing persistent fatigue in patients after treatment for cancer and performed secondary analyses to assess the effect of modafinil on cognitive function.METHODS:Breast cancer patients who reported a score of ≥2 on the Brief Fatigue Inventory were enrolled in the study. In phase 1 (P1), patients received 200 mg modafinil open‐label once daily for 4 weeks. In phase 2 (P2), patients with a positive response after P1 were randomized either to an additional 4 weeks of modafinil or to placebo. Tests of memory and attention selected from the Cognitive Drug Research (CDR) computerized cognitive assessment were performed at baseline (before modafinil) and after completing phases 1 and 2. The paired differences for each test score were subjected to a Wilcoxon signed rank test.RESULTS:Of the 82 women who were enrolled, 76 completed P1, and 68 completed all assessments in the study. Modafinil had a significant effect on the Speed of Memory (P = .0073) and Quality of Episodic Memory (P < .0001) during P1 of the study. After randomization at Week 8, those patients who continued modafinil demonstrated significantly greater improvement in Speed of Memory (P = .029), Quality of Episodic Memory (P = .0151), and mean Continuity of Attention (P = .0101) relative to the group that was switched to placebo.CONCLUSIONS:The authors found that modafinil improved cognitive performance in breast cancer survivors by enhancing some memory and attention skills. Although confirmation is needed, these findings suggest that modafinil may enhance quality of life in this patient population. Cancer 2009. © 2009 American Cancer Society.
Selective Enhancement of Carbon Nanotube Photoluminescence by Resonant Energy Transfer
Authors: Ahmad Ashraf , Kern Klaus , Balasubramanian Kannan 
Published: March 2009

AbstractHighly selective: Enhancement of the photoluminescence (PL) emission efficiency of selected chiral forms of semiconducting single‐walled carbon nanotubes (SWCNTs) is presented (see figure). Excitation of Nile blue A in the presence of SWCNTs results in the quenching of its fluorescence. The energy is resonantly transferred to the (7,5) SWCNT whereas the (8,7) tube is not in resonance; hence, its PL remains unaffected.magnified imageWe report on a simple method for enhancing the efficiency of photoluminescence (PL) emission from selected chiral forms of semiconducting single‐wall carbon nanotubes (SWCNTs). The method is based on the use of a fluorescent dye (Nile blue A) that shows the capability of resonant energy transfer on to nanotubes. The excitation of Nile blue A in the presence of SWCNTs results in the quenching of its fluorescence and the energy is resonantly transferred to certain chiral forms. The PL emission from these chiral forms shows a marked increase in efficiency signifying the occurrence of Förster type resonant energy transfer (FRET). Due to its simplicity, this procedure has widespread implications for the detection of carbon nanotubes as well as for their use as fluorophores in FRET‐based in vivo and in vitro biological applications.

Published: March 2009

AbstractAn electrochemical lithographic toolfor locally electrografting a non‐conducting organic coating on a conducting substrate with a submicrometer resolution is provided by atomic force scanning electrochemical microscopy (AFM‐SECM). The picture shows the topographic AFM image of the line pattern drawn with an AFM‐SECM tip on a gold surface by direct reduction of an aryl diazonium salt/acrylic acid electrolyte solution.magnified imageCombinations of scanning electrochemical microscopy (SECM) with other scanning probe microscopy techniques, such as atomic force microscopy (AFM), show great promise for directing localized modification, which is of great interest for chemical, biochemical and technical applications. Herein, an atomic force scanning electrochemical microscope is used as a new electrochemical lithographic tool (L‐AFM‐SECM) to locally electrograft, with submicrometer resolution, a non‐conducting organic coating on a conducting substrate.
Role of Excited States in Low‐Energy Electron (LEE) Induced Strand Breaks in DNA Model Systems: Influence of Aqueous Environment
Authors: Kumar Anil , Sevilla Michael D. 
Published: March 2009

AbstractLow‐energy electrons (LEEs) interact with a DNA model system to create a variety of excited states. In the gas phase, dissociative (σ*) states are accessible by LEEs with energy <4 eV (see picture) and cause facile strand breaks through a dissociative electron attachment mechanism. However, under solvation these dissociative (σ*) states are blue‐shifted and are less accessible to LEEs.magnified image
In Situ Plasmon‐Heating‐Induced Generation of Au/TiO2 “Hot Spots” on Colloidal Crystals
Authors: Alessandri Ivano , Ferroni Matteo , Depero Laura E. 
Published: March 2009

AbstractSERS you right: The plasmon heating of gold nanoshells is exploited to yield the local conversion of amorphous TiO2 into anatase on the surface of polymeric colloidal crystals (see scheme). The resulting Au/TiO2 spots are active substrates for surface‐enhanced Raman spectroscopy and allow surface reactions and processes to be followed directly on‐site.magnified image

Published: March 2009

AbstractLittle things count: The number of protons and the nature of cations of the dye influence the open‐circuit potential and the short circuit current of dye‐sensitized solar cells (DSCs, see picture). Thus, the effect of substituting the two tetrabutylammonium counter ions in the standard N719 dye by sodium ions allows the improvement on the performance and stability of DSCs.magnified imageWe report on the effect of substituting the two tetrabutyl ammonium counter ions of the standard N719 dye by sodium ions on the performance and stability of dye‐sensitized solar cells (DSCs). The disodium analogue of N719 in conjunction with a non‐volatile electrolyte gives a conversion efficiency of 7.6 % under standard global AM 1.5 sunlight. Devices maintain 99 % of their initial performance after 1000 h under full sunlight aging at 50 °C. Electrochemical impedance spectroscopy and photovoltage transient decay studies reveal the evolution of the solar cell parameters during aging. Remarkably, upon aging a decrease in the rate of electron back reaction with the triiodide ions across the TiO2/electrolyte interface appears as well as enhanced electronic conduction in the TiO2 film.
