Abstract
AIMS The aim of study was to evaluate the safety and efficacy of insulin detemir as a basal insulin switching from neutral protamine Hagedorn insulin (NPH) and insulin glargine in patients with diabetes on an intensive insulin therapy regimen. METHODS This 6-month multicentre, prospective, treat-to-target [glycosylated haemoglobin (HbA(1c) ) less than 6.5%] trial included 92 people with diabetes (61 type 1, 29 type 2 and two unknown diabetes types). Detemir was administered first with fixed dose and injection times and then adapted to optimal dose after 3 months. RESULTS Mean HbA(1c) (%) of all the subjects at months 4 to 6 of the study was improved compared with month 0 (7.34 ± 0.87, 7.28 ± 0.88, 7.25 ± 0.93 vs. 7.55 ± 1.18; p < 0.05 paired t-test). However, significant improvement was seen only among the patients who had previously used NPH as a basal insulin. Twice-daily injection of basal insulin increased among people in the type 1 previously injected insulin glargine. Total insulin dose increased in the type 1 glargine group. The mean body weight change in the highest quartile body mass index (BMI) group was from 70.7 to 69.3 kg over the 6 months. Quality of life (QoL) relating to the patients' glycaemic control tended to improve without a change in frequency of hypoglycaemia. CONCLUSIONS The results suggest that insulin detemir has a greater effect on glycaemic control in subjects with poor glycaemic control using NPH; can reduce or maintain body weight in obese patients; and obtains perceptive stability for patients with unstable glycaemic control.

Abstract
The anisotropy of the hot-electron velocity distribution in ultra-high-intensity laser produced plasma was studied with x-ray polarization spectroscopy using multilayer planar targets including x-ray emission tracer in the middle layer. This measurement serves as a diagnostic for hot-electron transport from the laser-plasma interaction region to the overdense region where drastic changes in the isotropy of the electron velocity distribution are observed. These polarization degrees are consistent with analysis of a three-dimensional polarization spectroscopy model coupled with particle-in-cell simulations. Electron velocity distribution in the underdense region is affected by the electric field of the laser and that in the overdense region becomes wider with increase in the tracer depth. A full-angular spread in the overdense region of 22.4 degrees -2.4+5.4 was obtained from the measured polarization degree.

Abstract
BACKGROUND AND PURPOSE Much interest is currently being focused on the anti-nociceptive effects mediated by nicotinic acetylcholine (nACh) receptors, including their location and mechanism of action. The purpose of this study was to elucidate these issues using 5-iodo-3-(2(S)-azetidinylmethoxy)pyridine (5IA), a nACh receptor agonist, and [(125)I]5IA. EXPERIMENTAL APPROACH We partially ligated the sciatic nerve of Sprague-Dawley rat to induce neuropathic pain [Seltzer's partial sciatic nerve ligation (PSL) model]. We then examined the changes in nACh receptor density in the CNS using [(125)I]5IA autoradiography and the involvement of nACh receptors in anti-nociceptive effects in the region where changes occurred. KEY RESULTS Autoradiographic studies showed that the accumulation of [(125)I]5IA and the number of nACh receptors in the thalamus of PSL rats were increased about twofold compared with those in the sham-operated rats. No change was observed in other brain regions. Rats injected in the ventral posterolateral thalamic nucleus (VPL) with 5IA demonstrated a significant and dose-dependent anti-allodynic effect and this effect was completely antagonized by mecamylamine, injected with 5IA, into the VPL. The blockade of nACh receptors in the VPL by mecamylamine decreased by 70% the anti-allodynic effect of 5IA, given i.c.v. Moreover, mecamylamine given intra-VPL by itself, induced significant hyperalgesia. CONCLUSIONS AND IMPLICATIONS Our findings suggest that the nACh receptors expressed in the VPL play an important role in the anti-allodynic effects produced by exogenous and endogenous agonists.

Abstract
Abstract
Purpose: The Y-box binding protein 1 (YB-1) regulates expression of P-glycoprotein (P-gp) encoded by the MDR1 gene. There have been no previous studies regarding the involvement of YB-1 in the development of resistance to paclitaxel. The present study was performed to examine how paclitaxel affects the localization and expression of YB-1 in breast cancer.Experimental Design: We evaluated the expression and localization of YB-1 and P-gp in breast cancer tissues obtained from 27 patients before and after treatment with paclitaxel. The effect of paclitaxel on localization of cellular YB-1 was examined by using GFP-YB-1. Interaction of YB-1 with the Y-box motif of the MDR1 promoters was studied by EMSA. The effects of paclitaxel on MDR1 promoter activity were examined by luciferase assay.Results: Of 27 breast cancer tissues treated with paclitaxel, nine (33%) showed translocation of YB-1 from the cytoplasm to the nucleus together with increased expression of P-gp during the course of treatment. Twelve breast cancer tissues (44%) showed neither translocation of YB-1 nor increased expression of P-gp. Nuclear translocation of YB-1 was correlated significantly with increased expression of P-gp (P=0.0037). Confocal analysis indicated that paclitaxel induced nuclear translocation of green fluorescent fused YB-1 in MCF7 cells. Furthermore, binding of YB-1 to the Y-box of MDR1 promoter was increased in response to treatment with paclitaxel. In addition, MDR1 promoter activity was significantly up-regulated by paclitaxel in MCF7 cells (p< 0.001).Conclusions: The results of the present study suggested that YB-1 may be involved in the development of resistance to paclitaxel in breast cancer.

Abstract
This retrospective study evaluated the safety and efficacy of combination chemotherapy using docetaxel and nedaplatin in an outpatient setting compared with those of chemotherapy using cisplatin (CDDP) and 5-Fu under hospitalization. Subjects comprised 21 patients who had been diagnosed with recurrent esophageal squamous cell carcinoma (ESCC), with 10 patients receiving combination chemotherapy comprising CDDP and 5-fluorouracil (5-Fu) under hospitalization (FP group; n = 10), and 11 patients receiving combination chemotherapy comprising docetaxel and nedaplatin in an outpatient setting (Doc/Ned group; n = 11). In the Doc/Ned group, patients received 30 mg/m(2) of docetaxel over a 1-h infusion on day 1, followed by 40 mg/m(2) of nedaplatin over a 2-h infusion on day 1 in an outpatient setting. In the Doc/Ned group, complete response was observed in two patients (18.1%), one with liver metastasis and one with abdominal lymph node metastasis, and two (18.1%) achieved partial response. In contrast, no complete responses were obtained in the FP group, and partial response was observed in only one patient (10.0%) with local recurrence. Response rates were thus 36.3% for the Doc/Ned group and 10.0% for the FP group. With a median follow-up of 234 days in the Doc/Ned group and 279 days in the FP group, median survival time (MST) was 234 days in the Doc/Ned group and 378 days in the FP group. No significant differences in MST were identified between groups. Thus regimen based on docetaxel and nedaplatin allows administration on an outpatient basis and appears feasible for recurrent ESCC as a second-line chemotherapy.
