Effect of microencapsulation on dyeing behaviors of disperse dyes without auxiliary solubilization
Authors: Yan Luo , Yi Zhong , Ben Zhang , Juan Du , Shuilin Chen 
Published: October 2010

AbstractMicroencapsulated disperse dye can be used to dye hydrophobic fabric in the absence of auxiliaries and without reduction clearing. However, little available information for dyeing practice is provided with respect to the effect of microencapsulation on the dyeing behaviors of disperse dyes. In this research, disperse dyes were microencapsulated under different conditions. The dyeing behaviors and dyeing kinetic parameters of microencapsulated disperse dye on PET fiber, e.g., dyeing curves, build up properties, equilibrium adsorption capacity C∞, dyeing rate constant K, half dyeing time t1/2, and diffusion coefficient D were investigated without auxiliary solubilization and compared with those of commercial disperse dyes with auxiliary solubilization. The results show that the dyeing behaviors of disperse dye are influenced greatly by microencapsulation. The diffusion of disperse dyes from microcapsule onto fibers can be adjusted by the reactivity of shell materials and mass ratios of core to shell. The disparity of diffusibility between two disperse dyes can be reduced by microencapsulation. In addition, the microencapsulation improves the utilization of disperse dyes due to no auxiliary solubilization. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2011
Water absorption and dimensional stability of short kenaf fiber‐filled polypropylene composites treated with maleated polypropylene
Authors: Law T. T. , Ishak Z. A. Mohd 
Published: October 2010

AbstractThe purpose of this research was to investigate the water absorption behavior and associated dimensional stability of kenaf‐polypropylene‐filled (PP/KF) composites. Composites with different fiber loadings, ranging from 0 to 40 wt %, were prepared with a twin‐screw extruder followed by hot press molding. The influence of the compatibilizer was also studied for PP/KF composite with 5 wt % maleated PP (MAPP). Water absorption testing was carried out at room temperature for 7 weeks. Tensile, flexural, and impact tests were also performed on control, wet, and re‐dried specimens. Increasing the fiber content resulted in higher water absorption and thickness swelling. The inferior mechanical properties of the wet composites were attributed to the effect of water, which deteriorates the interfacial properties of composites. On re‐drying, all properties were almost recovered because of the recovery of interfacial area as evident in scanning electron micrographs. Incorporation of the MAPP significantly improved the compatibility between the fiber and matrix and the mechanical properties of the composites compared with those without MAPP. It also diminished the water absorption as well as the related thickness swelling in the composites. © 2010 Wiley Periodicals, Inc. J Appl Polym Sci, 2010
Poly(para‐dioxanone)/poly(D,L‐lactide) blends compatibilized with poly(D,L‐lactide‐co‐para‐dioxanone)

AbstractThe effect of poly(D,L‐lactide‐co‐para‐dioxanone) (PLADO) as the compatibilizer on the properties of the blend of poly(para‐dioxanone) (PPDO) and poly(D,L‐lactide) (PDLLA) has been investigated. The 80/20 PPDO/PDLLA blends containing from 1% to 10% of random copolymer PLADO were prepared by solution coprecipitation. The PLADO component played a very important role in determining morphology, thermal, mechanical, and hydrophilic properties of the blends. Addition of PLADO into the blends could enhance the compatibility between dispersed PDLLA phase and PPDO matrix; the boundary between the two phases became unclear and even the smallest holes were not detected. On the other hand, the position of the Tg was composition dependent; when 5% PLADO was added into blend, the Tg distance between PPDO and PDLLA was shortened. The blends with various contents of compatibilizer had better mechanical properties compared with simple PPDO/PDLLA binary polymer blend, and such characteristics further improved as adding 5% random copolymers. The maximum observed tensile strength was 29.05 MPa for the compatibilized PPDO/PDLLA blend with 5% PLADO, whereas tensile strength of the uncompatibilized PPDO/PDLLA blend was 14.03 MPa, which was the lowest tensile strength. © 2010 Wiley Periodicals, Inc.

Evaluation of high performance fabric under light irradiation
Authors: Liu Xiaoyan , Yu Weidong , Pan Ning 
Published: October 2010

AbstractTo investigate the degradation characteristics of Kevlar fabric due to light irradiation, Kevlar fabric samples were irradiated using ATLAS 150S+ of xenon arc light for a range of time durations up to 168 h in this study. The UV–Vis spectrum showed that the transmittance and reflectance from the Kevlar samples decreased and the absorption increased along with the exposure time, showing a definite degradation tendency of Kevlar fabrics after light irradiation. The SEM pictures showed that there are some residual deposits or corrosion on the surface of the fibers after irradiated for 168 h. The DSC curve, FTIR, and X‐ray results showed the Kevlar fabric have a certain change but did not exhibit significant damage due to potential chemical interactions. © 2010 Wiley Periodicals, Inc.

Global exponential synchronization of stochastic switching networks with time‐varying delay
Authors: Liu Weikai , Guan Zhi‐Hong 
Published: October 2010

AbstractThis paper is concerned with the global exponential synchronization of stochastic delayed switching networks via hybrid control. The network under investigation is quite general to reflect the reality, where the network topology consists of r modes and switches from one mode to another according to a Markovian chain with known transition probability. Parameter uncertainties, time varying delay and stochastic disturbances are all taken into account in this study. Based on the Lyapunov functional method and stochastic analysis techniques, some new criteria for the global robust synchronization via hybrid control are established. Finally, one example with numerical simulation is given for illustration.Copyright © 2010 John Wiley and Sons Asia Pte Ltd and Chinese Automatic Control Society
Nutritional predictors of postoperative outcome in pancreatic cancer
Authors: Kanda M , Fujii T , Kodera Y , Nagai S , Takeda S , Nakao A 
Published: October 2010

Abstract

Background
Nutritional status plays an important role in the incidence of postoperative complications and the prognosis of various tumours. The prognostic value of preoperative nutritional factors in patients with pancreatic cancer is not known.

Methods
This retrospective study included 268 patients who underwent resection for adenocarcinoma of the pancreas. The predictive value of preoperative nutritional status for postoperative outcome (survival, complications) was assessed. Nutritional factors included the three constitutional indices, serum albumin and Onodera's prognostic nutrition index (PNI), calculated as 10 × serum albumin (g/dl) + 0·005× total lymphocyte count (per mm3).

Results
In multivariable analysis preoperative low PNI (but not low albumin) was an independent prognostic factor for poor survival: hazard ratio (HR) 1·73 (95 per cent confidence interval (c.i.) 1·21 to 2·47). The accuracy of a PNI value of less than 45 as cut-off for clinically significant preoperative malnutrition in predicting 1- or 2-year survival after surgery was, however, limited (66·4 and 56·3 per cent respectively). Low preoperative albumin concentration and PNI were significantly associated with postoperative complications: odds ratio 1·98 (95 per cent c.i. 1·18 to 3·32) and 2·14 (1·23 to 3·73) respectively. Low PNI and low body mass index were independently associated with pancreatic fistula: HR 2·52 (1·37 to 4·63) and 0·40 (0·17 to 0·93) respectively.

Conclusion
The PNI is associated with overall survival and postoperative complications, in particular pancreatic fistula, in patients with pancreatic cancer. The moderate accuracy of PNI as a predictor of survival limits its clinical use.

AbstractAsymmetrically substituted BODIPY analogues of the dye PM567 have been synthesised from 2‐acylpyrroles and pyrroles that bear indene, fluorene or difluorene units. The type of linkage between the fluorene and the BODIPY core plays an important role in the photophysics of the BODIPY chromophore. Indeed, an aliphatic bridge gives rise to an energy‐transfer process between the chromophores, whereas a vinyl spacer allows an electronic interaction between them, leading to a large red shift of the spectral bands. The laser action of the new dyes has been analysed under transversal pumping at 10 Hz repetition rate, in both liquid phase and incorporated into solid polymeric matrices. Lasing efficiencies of up to 40 % were reached with high photostabilities with the laser output remaining at the initial level after 1×105 pump pulses in the same position of the sample. The laser action of the new dyes outperforms the laser behaviour of commercial dyes that emit in the same spectral region. The replacement of fluorene by indene quenches the fluorescence and laser emission, but allows the development of an iron cation fluorescent sensor.
Retracted: Light‐Induced Bistability in Iron(III) Spin‐Transition Compounds of 5 X‐Salicylaldehyde Thiosemicarbazone (X=H, Cl, Br)

AbstractThe iron(III) spin‐crossover compounds [Fe(Hthsa)(thsa)]⋅H2O (1), [Fe(Hth5Clsa)(th5Clsa)2]⋅H2O (2), and [Fe(Hth5Brsa)(th5Brsa)2]⋅H2O (3) (H2thsa=salicylaldehyde thiosemicarbazone, H2th5Clsa=5‐chlorosalicylaldehyde thiosemicarbazone, and H2th5Brsa=5‐bromosalicylaldehyde thiosemicarbazone) have been synthesized and their spin‐transition properties investigated by magnetic susceptibility, Mössbauer spectroscopy, and differential scanning calorimetry measurements. The three compounds exhibit an abrupt spin transition with a thermal hysteresis effect. The more polarizable the substituent on the salicylaldehyde moiety, the more complete is the transition at room temperature with an increased degree of cooperativity. The molecular structures of 1 and 2 in the high‐spin state are revealed. The occurrence of the light‐induced excited‐spin‐state trapping phenomenon appears to be dependent on the substituent incorporated into the 5‐position of the salicylaldehyde subunit. Whereas the compounds with an electron‐withdrawing group (‐Br or ‐Cl) exhibit light‐induced trapped excited high‐spin states with great longevity of metastability, the halogen‐free compound does not, even though strong intermolecular interactions (such as hydrogen‐bonding networks and π stacking) operate in the system. For compound 2, the surface level of photoconversion is less than 35 %. In contrast, compound 3 displays full photoexcitation.
Simulation of extremes of diffusions
Authors: Gou Tingting , Murdoch Duncan 
Published: October 2010

AbstractThe authors consider the problem of simulating the times of events such as extremes and barrier crossings in diffusion processes. They develop a rejection sampler based on Shepp [Shepp, Journal of Applied Probability 1979; 16:423–427] for simulating an extreme of a Brownian motion and use it in a general recursive scheme for more complex simulations, including simultaneous simulation of the minimum and maximum and application to more general diffusions. They price exotic options that are difficult to price analytically: a knock‐out barrier option with a modified payoff function, a lookback option that includes discounting at the risk‐free interest rate, and a chooser option where the choice is made at the time of a barrier crossing.

Monitoring molecular response in chronic myeloid leukemia
Authors: Cortes Jorge , Quintás‐Cardama Alfonso , Kantarjian Hagop M. 
Published: October 2010

AbstractBefore the advent of tyrosine kinase inhibitor (TKI) therapy, the evaluation of hematologic and cytogenetic responses was sufficient to gauge treatment efficacy in patients with chronic myeloid leukemia. However, with more potent TKI therapies, the majority of patients achieve complete cytogenetic response. Furthermore, deeper molecular responses are now commonly achieved, necessitating a reliance on molecular monitoring to assess residual leukemic disease. The prognostic significance between molecular responses and duration of complete cytogenetic response, progression‐free survival, and event‐free survival is described herein. A discussion of the concept of complete molecular response is also provided, and the potential for imatinib treatment discontinuation is evaluated. The implications of rising BCR‐ABL1 transcript levels and caveats of molecular monitoring are also described. Cancer 2011. © 2010 American Cancer Society.

AbstractBACKGROUND:Anemia is a frequent side effect of imatinib in patients with chronic myeloid leukemia (CML). Erythropoietic‐stimulating agents have been used for treatment of imatinib‐induced anemia. There are no data on long‐term safety of erythropoietic‐stimulating agents in CML patients.METHODS:The records of chronic phase CML patients who received treatment with imatinib were reviewed for use of erythropoietic‐stimulating agents and occurrence of thrombotic events. Data on cytogenetic response and survival were analyzed by use of erythropoietic‐stimulating agent.RESULTS:A total of 608 patients were included, and 217 patients received erythropoietic‐stimulating agents. There were 30 thrombotic episodes. Patients who received erythropoietic‐stimulating agents had a higher rate of thrombosis (8.5% vs 2.6%,P= .0025). There was no difference in cytogenetic response rate and survival by use of erythropoietic‐stimulating agent. Development of grade 3‐4 anemia occurred in 62 (10%) patients and was associated with significantly worse response and survival in patients in late chronic phase. By multivariate analysis, use of erythropoietic‐stimulating agents was not a risk factor for event‐free survival.CONCLUSIONS:In our cohort of chronic phase CML patients, use of erythropoietic‐stimulating agents did not impact survival or cytogenetic response rate, but was associated with a higher thrombosis rate. Severe anemia is associated with worse survival and response. Cancer 2011. © 2010 American Cancer Society.

AbstractBACKGROUND:Recently, the Functional Assessment of Cancer Therapy‐Gastric (FACT‐Ga) was developed to measure the quality of life (QoL) of patients with gastric cancer. This newly developed instrument has not yet been validated.METHODS:Eighty‐two patients with gastric adenocarcinoma completed questionnaires at baseline. The FACT‐Ga scores were measured as a function of disease stage and performance status, and they were correlated with the Medical Outcomes Study 36‐item short‐form health survey (SF‐36), the Beck Depression Inventory‐II, the Marlow‐Crowne Social Desirability Scale, the Paulhus Deception Scale, and the State‐Trait Anxiety Inventory. Patients received a second questionnaire 2 weeks after baseline to evaluate test‐retest reliability and again at 3 months to evaluate the sensitivity of the FACT‐Ga to changes in performance status and to estimate the minimally important differences in scores that represented meaningful change.RESULTS:The internal and test‐retest reliability of the FACT‐Ga instrument was adequate. With the exception of the social well being subscale, all FACT‐Ga scores were correlated as hypothesized with other measures. Relevant components of the FACT‐Ga were sensitive to changes in performance status.CONCLUSIONS:The current results indicated that the FACT‐Ga provides a valid and reliable measurement of QoL in patients with gastric adenocarcinoma. It is a useful instrument for QoL assessment in clinical trials, and it also may be useful for the detection of significant changes in the QoL of individual patients.

AbstractBACKGROUND:Cancer biomarkers are the backbone for the implementation of individualized approaches to bladder cancer (BCa). Hyaluronic acid (HA) and all 7 members of the HA family, that is, HA synthases (HA1, HA2, HA3), HYAL‐1 hyaluronidase, and HA receptors (CD44s, CD44v, and RHAMM), function in tumor growth and progression. However, the diagnostic and prognostic potential of these 7 HA family members has not been compared simultaneously in any cancer. We evaluated the diagnostic and prognostic potential of HA family members in BCa.METHODS:Using quantitative PCR and immunohistochemistry, expression of HA family members was evaluated in prospectively collected bladder tissues (n = 72); mean and median follow‐up were 29.6 ± 5.3 and 24 months, respectively. Transcript levels were also measured in exfoliated urothelial cells from urine specimens (n = 148).RESULTS:Among the HA family members, transcript levels of the HA synthases, HYAL‐1, CD44v, and RHAMM were 4‐ to 16‐fold higher in BCa tissues than in normal tissues (P < .0001); however, CD44s levels were lower. In univariate and multivariate analyses, tumor stage (P = .003), lymph node invasion (P = .033), HYAL‐1 (P = .019), and HAS1 (P = .027) transcript levels, and HYAL‐1 staining (P = .021) were independently associated with metastasis. Tumor stage (P = .019) and HYAL‐1 (P = .046) transcript levels were also associated with disease‐specific mortality. Although HA synthase and HYAL‐1 transcript levels were elevated in exfoliated urothelial cells from BCa patients, the combined HAS2–HYAL‐1 expression detected BCa with an overall sensitivity of 85.4% and a specificity of 79.5% and predicted BCa recurrence within 6 months (P = .004; RR = 6.7).CONCLUSIONS:HYAL‐1 and HAS1 expression predicted BCa metastasis, and HYAL‐1 expression also predicted disease‐specific survival. Furthermore, the combined HAS2–HYAL‐1 biomarker detected BCa and significantly predicted its recurrence. Cancer 2011. © 2010 American Cancer Society.

AbstractBACKGROUND:We previously reported that a single prostate‐specific antigen (PSA) measured at ages 44‐50 was highly predictive of subsequent prostate cancer diagnosis in an unscreened population. Here we report an additional 7 years of follow‐up. This provides replication using an independent data set and allows estimates of the association between early PSA and subsequent advanced cancer (clinical stage ≥T3 or metastases at diagnosis).METHODS:Blood was collected from 21,277 men in a Swedish city (74% participation rate) during 1974‐1986 at ages 33‐50. Through 2006, prostate cancer was diagnosed in 1408 participants; we measured PSA in archived plasma for 1312 of these cases (93%) and for 3728 controls.RESULTS:At a median follow‐up of 23 years, baseline PSA was strongly associated with subsequent prostate cancer (area under the curve, 0.72; 95% CI, 0.70‐0.74; for advanced cancer, 0.75; 95% CI, 0.72‐0.78). Associations between PSA and prostate cancer were virtually identical for the initial and replication data sets, with 81% of advanced cases (95% CI, 77%‐86%) found in men with PSA above the median (0.63 ng/mL at ages 44‐50).CONCLUSIONS:A single PSA at or before age 50 predicts advanced prostate cancer diagnosed up to 30 years later. Use of early PSA to stratify risk would allow a large group of low‐risk men to be screened less often but increase frequency of testing on a more limited number of high‐risk men. This is likely to improve the ratio of benefit to harm for screening. Cancer 2011. © 2010 American Cancer Society.

AbstractBACKGROUND:This study was designed to assess the activity and safety of dose‐adjusted infusional cyclophosphamide, doxorubicin, vincristine, and prednisone chemotherapy with rituximab (DA‐POCH‐R) in elderly patients with poor‐prognostic untreated diffuse large B‐cell non‐Hodgkin lymphoma (DLBCL).METHODS:From April 2006 to November 2009, 23 patients, aged ≥70 years, with an age‐adjusted International Prognostic Index (IPI) of 2 or 3, were enrolled. Only patients with left ventricular ejection fraction (LVEF) ≥50% were allowed. The DA‐POCH‐R regimen was administered every 3 weeks for a minimum of 6 and a maximum of 8 cycles.RESULTS:Median patient age was 77 years (range, 70‐90 years); 83% of patients had Ann Arbor stage III to IV disease. Median LVEF at baseline was 62%. Four (17%) patients had a history of abnormal cardiovascular conditions. Twenty‐one (91%) patients were evaluable for response. The overall response rate was 90%, with a complete response rate of 57%. The 3‐year overall survival and event‐free survival rates were 56% and 54%, respectively. Neutropenia (48%) was the most frequent grade 3 to 4 adverse event (AE); no grade 3 to 4 cardiac AEs were observed.CONCLUSIONS:DA‐POCH‐R was an active and safe combination therapy for patients aged ≥70 years with poor‐prognostic untreated DLBCL. This regimen was a reasonable alternative for elderly patients who were not considered to tolerate standard R‐CHOP treatment. Cancer 2011. © 2010 American Cancer Society.
