Depression of the melting temperature by moisture for α‐form crystallites in human hair keratin
Authors: Cao Jinan , Leroy Frédéric 
Published: December 2004

AbstractDSC thermal analysis has been carried out for human hair samples with various moisture contents to investigate the melting temperature depression behavior of α‐form crystallites in human hair. This is achieved by adopting a novel technique using silicon oil as the thermal medium, which permits hair samples to retain a range of moisture contents in between completely dry and fully saturated. The results show that the melting temperature of the α‐form crystallites in human hair varies with moisture content from 205°C for dry hair to 155°C for the hair sample with moisture content of 23%. These experimental results are particularly useful for clarification of the conceptual ambiguities associated with the molecular properties of α‐helices and α‐form crystallites. Furthermore, the Flory–Huggins theory was employed to determine the water–helix interaction parameter (χ = 4.5) and the α‐form crystallinity of human hair (22%), a figure consistent with that obtained by the XRD method (21%). © 2004 Wiley Periodicals, Inc.

Published: December 2004

AbstractBACKGROUNDA nomogram for predicting long term tumor‐specific death in patients with soft tissue sarcoma (STS) was developed at the Memorial Sloan‐Kettering Cancer Center (MSKCC).METHODSTo assess the performance of the MSKCC nomogram, 642 consecutive patients with extremity STS who underwent surgery over a 20‐year span at a single referral center were analyzed. Nomogram predictions were based on tumor size, depth, site, patient age, histologic subtype, and grade. The latter, at variance with the system in use at the MSKCC, was classified as Grade 1–3 according to the French Federation of Cancer Centers Sarcoma Group (FNCLCC) system. The statistical approach used for nomogram performance assessment was that of “validation by calibration” proposed by Van Houwelingen.RESULTSGraphic comparison of observed and predicted sarcoma‐specific survival curves showed that predictions by the nomogram were quite accurate, within 10% of actual survival for all prognostic strata. Statistical analysis showed that such predictions could be improved by employing approximately 25% shrinkage to achieve good calibration. The contribution of histologic grade was highly significant in both univariate analysis (P < 0.001) and multivariate analysis (P < 0.001), and a survival trend across the 3 grade categories was observed. Based on those findings, a nomogram that included the FNCLCC histologic grade classification was produced.CONCLUSIONSResults of the current study confirmed that the MSKCC nomogram is a valuable tool for individual prognostic assessment. A nomogram that included the FNCLCC histologic grade classification was proposed and was validated internally. Cancer 2005. © 2004 American Cancer Society.
Weekly docetaxel is safe and effective in the treatment of advanced‐stage acquired immunodeficiency syndrome‐related Kaposi sarcoma
Authors: Lim Soon Thye , Tupule Anil , Espina Byron M. , Levine Alexandra M. 
Published: December 2004

AbstractBACKGROUNDIntravenous paclitaxel, 100 mg/m2, given over 3 hours every 2 weeks is associated with a response rate of 59% in patients with recurrent or refractory acquired immunodeficiency syndrome (AIDS)‐related Kaposi sarcoma (KS). However, this regimen is associated with significant myelosuppression, and the inconvenience of a 3‐hour infusion. Moreover, no effective therapies have been defined for use after treatment failure with this agent. A Phase II trial was conducted with weekly docetaxel in patients with advanced‐stage KS to assess safety and antitumor activity.METHODSDocetaxel was administered at a dose of 25 mg/m2 intravenously over 15–30 minutes weekly for 8 weeks. Thereafter, if the patient experienced stable disease or better response, treatment doses were given every other week until complete disease remission, disease progression, or unacceptable toxicity occurred.RESULTSTwelve patients were accrued—9 had > 25 mucocutaneous lesions, 1 had lymphedema, and 2 had visceral involvement. Ten patients (83%) had previous systemic chemotherapy, including 4 who received previous paclitaxel. Treatment was well tolerated, with no Grade 4 toxicity of any type. Grade 3 neutropenia occurred in 33% of patients but no patient had neutropenic fever. Five patients (42%) achieved a partial response, including 1 who had previously failed to respond to paclitaxel. The median time to disease progression was 26 months (range, 5–53 months). With a median follow‐up period of 45 months, the median survival point had not been reached.CONCLUSIONSWeekly docetaxel is safe, with reasonable antitumor activity in patients with advanced‐stage, recurrent, or refractory AIDS‐related KS.

Determining the Gibbs Energy of Ion Transfer Across Water–Organic Liquid Interfaces with Three‐Phase Electrodes
Authors: Scholz Fritz , Gulaboski Rubin 
Published: December 2004

AbstractIons can be transferred between immiscible liquid phases across a common interface, with the help of a three‐electrode potentiostat, when one phase is an organic droplet attached to a solid electrode and containing a redox probe. This novel approach has been used in studies to determine the Gibbs energy of anion and cation transfer, ranging from simple inorganic and organic ions to the ionic forms of drugs and small peptides. This method of studying ion transfer has the following advantages: 1) no base electrolytes are necessary in the organic phase; 2) the aqueous phase contains only the salt to be studied; 3) a three‐electrode potentiostat is used; 4) organic solvents such as n‐octanol and chiral liquids such as D‐ and l‐2‐octanol can be used; 5) the range of accessible Gibbs energies of transfer is wider than in the classic 4‐electrode experiments; 6) the volume of the organic phase can be very small, for example, 1 μL or less; 7) the experiments can be performed routinely and fast. Herein, the basic principle is outlined, as well as a summary of the results obtained to date, and a discussion on the theoretical treatments concerning the kinetic regime of the three‐phase electrodes with immobilized droplets.
A pilot study of psychodynamic psychotherapy for adult survivors of childhood sexual abuse

Published: December 2004

AbstractClinical samples of child sexual abuse survivors report a variety of psychiatric symptoms and interpersonal difficulties. The treatment outcome literature for this population is often incomplete due to numerous methodological constraints. The purpose of this study was to evaluate the effectiveness of an open trial of individual short‐term, psychodynamic psychotherapy with a naturalistic sample of adult survivors of childhood sexual abuse. Sexual abuse survivors demonstrated significant improvement in symptomatic distress, level of functioning and dynamic personality variables according to self‐report measures and clinical rating scales. Abuse survivors developed positive therapeutic alliances, which remained high throughout the course of treatment, and comparable to the non‐abused clinical sample. Sexual abuse survivors' response to treatment was similar to that of non‐abused patients, with the potential for greater change in feelings about the self. These findings demonstrate that psychodynamic psychotherapy may be useful for childhood sexual abuse survivors presenting with depressive symptoms and interpersonal difficulties. Copyright © 2004 John Wiley & Sons, Ltd.
VBR video transmission with isochronous and asynchronous transfer mode over wireless 1394

Published: December 2004

AbstractWe propose a VBR video transmission scheme with isochronous and asynchronous transfer mode over Wireless 1394. In the proposed scheme, to decrease the idle bandwidth in the isochronous area, a video station which uses the isochronous transfer mode is assigned bandwidth equivalent to the average rate of the video stream. Video data over the average rate are transmitted in asynchronous transfer mode, and video stations have higher transmission priority than data stations in asynchronous transfer mode. By computer simulations, we show that the proposed scheme can improve the channel utilization performance and the waiting time performance, and that it is effective for VBR video transmission. © 2004 Wiley Periodicals, Inc.

New pulse compression filter to realize minimum S/N loss with zero range side lobe
Authors: Shinonaga Mitsuyoshi , Yajima Shinichi , Nishimoto Shinkichi 
Published: December 2004

AbstractPulse compression processing of chirped signals can be treated as a matched filter reception process. However, generation of range side lobes is unavoidable. If a window function is used for suppression of these range side lobes, S/N loss occurs due to signal loss. Although it is possible to derive a window function realizing a desired characteristic such as side lobe‐free conditions by means of a convergence operation, it is not known whether the S/N loss is minimized because the requirement for S/N loss minimization is not taken into account. In the present paper, a method is presented for calculation of the window function and the pulse compression filter satisfying both the S/N loss minimum condition and the side lobe‐free condition. Simulation confirms that the derived pulse compression filter has a lower S/N loss than that in the method with a conventional window function and has a higher range resolution. © 2004 Wiley Periodicals, Inc.
