Absolute configuration assignment of (3‐phenyloxirane‐2,2‐diyl)bis(phenylmethanone) via density functional calculations of optical rotation and vibrational circular dichroism
Authors: Lattanzi Alessandra , Russo Alessio , Rizzo Paola , Monaco Guglielmo , Zanasi Riccardo
Published: April 2010

Density Functional Theory (DFT) calculations of optical rotation (OR) and vibrational circular dichroism (VCD) have been used to assign the absolute configuration (AC) of a recently prepared (3‐phenyloxirane‐2,2‐diyl)bis(phenylmethanone), 3, by asymmetric epoxidation of the corresponding 2‐arylidene‐1,3‐diketone. The experimental OR at 589.3 nm and the VCD spectrum of the (+)‐ and (−)‐enantiomer of 3 have been measured. The conformationally‐averaged OR value and VCD spectrum of (R)‐3 were calculated at B3LYP/6‐311G(2d,2p) level of theory. Both approaches provide the same absolute configuration of the stereogenic carbon, i.e. the AC of (+)‐3 is (R)‐3, thus affording a confident assignment. Only two conformational isomers of 3 have been predicted to be populated at ambient temperature. Their presence is directly observed in the VCD spectrum. Chirality 2010. © 2010 Wiley‐Liss, Inc.

Authors: Pan Mugang , Wan Decheng , Huang Junlian
Published: April 2010

A novel copolymer (PG‐PNIPAM) composed of polyglycerol (PG) as core and poly(N‐isopropylacrylamide) (PNIPAM) as arms was prepared by the radical addition‐fragmentation transfer polymerization (RAFT) of NIPAM in the presence of PG with multi‐trithiolcarbonate groups (PG‐TTC). The results showed that the RAFT polymerization was controllable and nearly all trithiolcarbonates groups on PG took part in the polymerization. The final PG‐PNIPAM copolymer showed a thermally dependent hydrophobic/hydrophilic transition around 28–30°C.

Published: April 2010

A new adsorbent, modified mesoporous lanthanum(III) silicate, has been prepared with various molar ratios of Si/La (10, 20, 40, 80) and cethyltrimethylammonium bromide (CTAB) as structure directing agent. XRD, nitrogen sorption, SEM, IR, thermogravimetry and sorption of radionuclides and toxic metal ions have been studied. The results show that adsorption amount of some element such as Pb(II) and Th(IV) has been increased significantly by incorporation of lanthanum ions in the framework of adsorbent. Separation of Co(II)‐Th(IV), Co(II)‐U(VI) and Mo(VI)‐U(VI) has been developed on columns of this adsorbent.

Measuring Quantitatively the Deterioration Degree of Ancient Silk Textiles by Viscometry
Authors: Zhang Xiaomei , Yuan Sixun
Published: April 2010

Silk is made of natural protein, and can be damaged by heat, light, hydrolysis, etc. It deteriorates during burial, storage, display, studying and conservation treatment such as cleaning. Ancient silk fabrics are very precious, so their deterioration in museums has long been a concern for many conservators. To better preserve these textiles, early detection and quantitative assessment of damage is essential. Modern cultivated silk samples were artificially aged by simulating three main natural aging factors: light, heat and hydrolysis. Using these samples, the potential of viscometry for the quantitative assessment of silk damage was studied systematically by comparing with tensile strength testing. The results of this research show that viscometry is sensitive to the small changes in silk molecular weight resulting from deterioration. The technique is a useful method for the detection of ancient silk fabrics.

Published: April 2010

A method of bubble fractionation was developed for the resolution of racemic mandelic acid (MA), using 2‐hydroxypropyl‐β‐cyclodextrin (HP‐β‐CD) as chiral collector. The influences of concentration of HP‐β‐CD, reflux equilibriation time, gas flow rate, packing height of column and pH of buffer on resolution performance were investigated, respectively. According to the similar physical behavior of bubble fractionation and chemical reaction processes, the equivalent chemical reaction constant was introduced. The resolution process was preliminarily analyzed by means of kinetics. The results show that the enantiomeric excess of 60.7% can be obtained under the optimal conditions. The process could be regarded as a first order chemical reaction, where the equivalent speed constant was kl=0.00376. This method is helpful for realizing high resolution and linear amplification of device.
Modified weights based generalized quasilikelihood inferences in incomplete longitudinal binary models
Authors: Sutradhar Brajendra C. , Mallick Taslim S.
Published: April 2010

In an incomplete longitudinal set up, a small number of repeated responses subject to an appropriate missing mechanism along with a set of covariates are collected from a large number of independent individuals over a small period of time. In this set up, the regression effects of the covariates are routinely estimated by solving certain inverse weights based generalized estimating equations. These inverse weights are introduced to make the estimating equation unbiased so that a consistent estimate of the regression parameter vector may be obtained. In the existing studies, these weights are in general formulated conditional on the past responses. Since the past responses follow a correlation structure, the present study reveals that if the longitudinal data subject to missing mechanism are generated by accommodating the longitudinal correlation structure, the conditional weights based on past correlated responses may yield biased and hence inconsistent regression estimates. The bias appears to get larger as the correlation increases. As a remedy, in this paper the authors proposed a modification to the formulation of the existing weights so that weights are not affected directly or indirectly by the correlations. They have then exploited these modified weights to form a weighted generalized quasi‐likelihood estimating equation that yields unbiased and hence consistent estimates for the regression effects irrespective of the magnitude of correlation. The efficiencies of the regression estimates follow due to the use of the true correlation structure as a separate longitudinal weights matrix in the estimating equation.

A prospective cohort study defining utilities using time trade‐offs and the Euroqol‐5D to assess the impact of cancer‐related lymphedema
Authors: Cheville Andrea L. , Almoza Mously , Courmier Janice N. , Basford Jeffrey R.
Published: April 2010

BACKGROUND:

The devastating impact of lymphedema on cancer survivors' quality of life has prompted consideration of several changes in medical and surgical care. Unfortunately, our understanding of the benefits gained from these approaches relative to their cost remains limited. This study was designed to estimate utilities for lymphedema and characterize how utilities differ between subgroups defined by lymphedema etiology and distribution.

METHODS:

A consecutive sample of 236 subjects with lymphedema seen at a lymphedema clinic completed both a time trade‐off (TTO) exercise and the Euroqol 5D. Responses were adjusted in multivariate regression models for demographic factors, comorbidities, and lymphedema severity/location.

RESULTS:

Most participants (167 of 236, 71%) had lymphedema as a consequence of cancer treatment; 123 with breast cancer and upper extremity involvement. Mean TTO utility estimates were consistently higher than Euroqol 5D estimates. Unadjusted TTO (0.85; standard deviation [SD], 0.21) and Euroqol 5D (0.76; SD, 0.18) scores diminished with increasing lymphedema stage and patient body mass index (BMI). Adjusted utility scores were lowest in patients with cancer‐related lower extremity lymphedema (TTO = 0.82; SD, 0.04 and Euroqol 5D = 0.80; SD, 0.03). Breast cancer patients also had lower adjusted Euroqol 5D scores (0.80; SD, 0.02).

CONCLUSIONS:

Lymphedema‐associated utilities are in the range of 0.80. Lower utilities are observed for patients with higher lymphedema stages, elevated BMI, and cancer‐related lymphedema. Greater expenditures for the prevention and treatment of cancer‐related lymphedema are warranted. Cancer, 2010. © 2010 American Cancer Society.

Authors: Lorenz Karl A. , Malin Jennifer L.
Published: April 2010

Impending fiscal constraints may require blunt tools to reduce expenditures, and end‐of‐life care has to be transformed to achieve better system efficiency. Therefore, advanced cancer care urgently needs to adopt a quality focus, to assure that reforms to payment and delivery promote both efficiency as well higher quality patient and family‐centered care.

BACKGROUND:

Based on an analysis of 1852 retrospectively evaluated patients with metastatic spinal cord compression (MSCC), a scoring system was developed to predict survival. This study was performed to validate the scoring system in a new data set.

METHODS:

The score included 6 prognostic factors: tumor type, interval between tumor diagnosis and MSCC, other bone or visceral metastases, ambulatory status, and duration of motor deficits. Scores ranged between 20 and 45 points, and patients were initially divided into 5 groups: those with 20 to 25 points, those with 26 to 30 points, those with 31 to 35 points, those with 36 to 40 points, and those with 41 to 45 points. To facilitate the clinical use of the score, the patients were regrouped into 3 groups: those with 20 to 30 points, those with 31 to 35 points, and those with 36 to 45 points. In this study, data of 439 new patients were included who were divided into the same prognostic groups as in the preceding study.

RESULTS:

In this study, the 6‐month survival rates were 7% (for those with 20‐25 points), 19% (for those with 26‐30 points), 56% (for those with 31‐35 points), 73% (for those with 36‐40 points), and 90% (for those with 41‐45 points), respectively (P < .0001). After regrouping, the 6‐month survival rates were 14% (for those with 20‐30 points), 56% (for those with 31‐35 points), and 80% (for those with 36‐45 points), respectively, in this study (P < .0001).

CONCLUSIONS:

In the current study, the difference in 6‐month survival between the prognostic groups was found to be as significant as in the preceding study. Thus, this scoring system was considered valid to estimate survival of MSCC patients. The system could have been simplified by including only 3 instead of 5 prognostic groups.
