A preliminary report on a randomized trial on 83 stage III or IV locally advanced squamous cell head and neck cancer (SCHNC) patients demonstrated improved 2-yr disease-free survival (65% vs 41%, p = 0.01) and increased rate of local control (85% vs 59%, p < 0.05) in the concomitant chemoradiation group (cisplatin 50 mg/m2 weekly) in comparison to radiation therapy alone (25). It should be noted that the DFS was improved overall in the concomitant arm despite 18% patients receiving only two-thirds of their scheduled dose of cisplatin as a result of nausea and vomiting. Mature results from this study have not been published to date. 

The structure of a typical nerve is shown in Fig. A2.1. The nucleus of the cell is found in the large cell body situated at one end of the nerve cell. Small arms (dendrites) radiate from the cell body and receive messages from other nerves. These messages either stimulate or destimulate the nerve. The cell body collects the sum total of these messages. 

Master Computer software. This program does not need to send or receive signals from any controller, but receives signals from each of the computers in the cell. It is responsible for directing the operations of the entire sequence of the cell for example, when it receives the signal that a machine-tool has finished a piece and that the door is open, it sends a signal to the robotic arm to pick up the piece and take it to the next location. The user interface of this program is a drop down menu that yields a list of all the control computers connected to the system. When we select one of them, we can see the virtual representation of the associated element. 

Cation transport experiments were performed in a U-tube glass cell (2.0 cm, i.d.) as reported before. The carrier in CH Cl or CHCl (12 ml) was placed in the base of the U-tube, and two aqueous phases (5 ml, each) were placed in the arms of the U-tube, floating on the membrane phase. The membrane phase was stirred constantly with a magnetic stirrer. The transport rates were calculated from the initial rates of appearance of guest cations and cotransported anion (C10 ) into the receiving aqueous phase, which were determined by means of ion selective electrodes (Orion Model 92-32 for Ba 94-82 for Pb 95-12 for NH 93-19 for K 93-81 for C10 ). 

Avastin was studied in NSCLC and approved in 2006 for NSCLC treatment in combination with carbo-platin and paclitaxel for the initial systemic treatment of patients with unresectable, locally advanced, recurrent or metastatic, non-squamous, non-small cell lung cancer. An improvement in survival time was reported when Avastin was added to a standard chemotherapy regimen. A multi-center clinical trial supporting this approval enrolled 878 patients who had not received prior chemotherapy (Sandler et al. 2006). The trial compared the effectiveness of Avastin plus carboplatin and pacUtaxel with chemotherapy by carboplatin and paclitaxel alone. The median overall survival time for patients in the Avastin plus carboplatin and pacUtaxel arm was 12.3 vs 10.3 months for patients receiving only carboplatin and paclitaxel. 

Another Raf kinase inhibitor, sunitinib (Sutent), was approved in 2006 based on a multi-center, international randomized trial enrolling 750 patients with treatment-naive metastatic renal cell carcinoma (Motzer et al. 2007). In that study, patients were randomized to receive either Sutent or interferon-a (IFN-a). Common metastatic sites included lung, lymph nodes, bone, and liver. There were 96 events (25.6%) of progression/death on Sutent compared with 154 events (41.1%) on IFN-a. Median progression-free survival was 47.3 weeks for Sutent-treated patients and 22.0 weeks for patients treated with IFN. Objective response rate on the Sutent arm was 27.5 vs 5.3% on IFN-a arm. 

Synthetic bulk liquid membranes consist of a cyhndrical glass vessel and a coaxially arranged glass cylinder, which separates the two aqueous phases (Fig. 6a) [332,333]. In the U-shaped cell (Fig. 6b), the separation of the receiving and the source aqueous phase is accomplished by means of the two side arms [334,335]. H-type cells (Fig. 6c) represent a modification of the U-shaped cell and also work with a less dense solvent (e.g., 1-hexanol) as the liquid membrane component [336]. 

The study of tethered polymer chains is an area which has received increasing attention in recent years. These are systems in which one or both ends of the chain are constrained in their motion because they are attached to a d dimensional surface. This surface could be a point or small central core (d = 0) as in the case of a many-arm star polymer, a line (d = 1) as in the case of a comb polymer, or a flat surface (d = 2) as in the case of a polymer brush. Polymers attached to themselves to form a polymer network or a tethered membrane are also examples of tethered chain systems. An interesting example of a tethered membrane is the spectrin/actin membrane skeleton of the red blood cell skeleton. A schematic illustration of these four examples of tethered chain is shown in Fig. 9.1. Additional interest in tethered chains is due to their technological applications in colloidal stabilization and lubrication. ... 

A Phase-2 clinical study of IMO-2055 monotherapy in renal cell carcinoma with four arms has been reported [120]. In this study treatment, naive and second-line patients received IMO-2055 subcutaneously at either 0.16 or 0.64 mg/kg/week. The median PFS was 4.5 and 1.9 months for the 0.16- and 0.64-mg/kg/week treatment-naive patients, and 3.4 and 4.3 months for the 0.16- and 0.64-mg/kg/ week second-line patients, respectively. Median overall survival was 23.5 months over aU arms, with 58% of patients having stable disease. Two patients have shown partial responses. Seven patients received weekly IMO-2055 treatment for at least 1 year. IMO-2055 treatment was generally well tolerated at the dose levels studied. The primary objective of tumor response, based on response evaluation criteria in solid tumors (RECIST), was not achieved in the study [120].
