OBJECTIVE New effective therapy is desirable for patients with non-small cell lung cancer (NSCLC) who have failed previous treatments. Fractionated administration of paclitaxel may be less toxic and more active against NSCLC. The aim of this study was to evaluate the activity and toxicity of weekly paclitaxel therapy for NSCLC in a second-line setting. (More)
The effectiveness and toxicity of many drugs vary depending on the relationship between the dosing schedule and the 24-hour rhythms of biochemical, physiological and behavioral processes. In addition, several drugs can cause alterations to the 24-hour rhythms leading to illness and altered homeostatic regulation. However, the mechanisms of this drug-based(More)
The mammalian circadian clock is located in the suprachiasmatic nucleus (SCN) of the hypothalamus and in most peripheral tissues. Clock genes drive the biological clock. However, circadian expression variations of the human clock genes are still unclear. In this study, we analyzed the daily variations of mPer2 and mClock mRNA expression in both the mouse(More)
STUDY OBJECTIVE The breath-to-breath variability of respiratory parameters changes with sleep stage. This study investigates any alteration in the approximate entropy (ApEn) of respiratory movement as a gauge of complexity in respiration, by stage of consciousness, in the light of putative brain interactions. PARTICIPANTS Eight healthy men, who were(More)
Entropy measurement can discriminate among complex systems, including deterministic, stochastic and composite systems. We evaluated the changes of approximate entropy (ApEn) in signals of the electroencephalogram (EEG) during sleep. EEG signals were recorded from eight healthy volunteers during nightly sleep. We estimated the values of ApEn in EEG signals(More)
In order to examine the pathology in patients with obstructive sleep apnoea/hypopnoea syndrome (OSAHS), the nonlinear properties of respiratory movement and breath-to-breath variations during resting wakefulness with eyes closed was investigated. Recording of the respiratory movement using inductive plethysmography was performed on 14 patients with OSAHS(More)
The combination of trastuzumab with paclitaxel (PTX) is an important option for the treatment of HER2-positive breast cancer. Dexamethasone (Dex) premedication is routinely used in the treatment with PTX. The interactions among Dex, PTX and trastuzumab were evaluated in BT-474 cells. Dex interfered with trastuzumab-induced cell growth inhibition without(More)
Although surgery is the usual management strategy for acquired benign tracheoesophageal fistula, sometimes this approach is contraindicated or the patient declines surgical management. In this report, we describe a case of a patient with tracheoesophageal fistula at the level of the carina due to bronchial arterial infusion chemotherapy. Closure could not(More)
Irinotecan is used widely in the treatment of several malignancies, but unpredictable severe toxicities such as myelosuppression and delayed-type diarrhea are sometimes experienced. Polymorphism of the UGT1A1 gene is one of the likely reasons for interindividual differences in irinotecan pharmacokinetics and severe toxicity. Also, polymorphic organic(More)
Paclitaxel is used frequently in the treatment of advanced non-small cell lung cancer. This study was carried out in order to determine the role of extracellular signal-regulated kinases (ERK) and retinoblastoma protein (pRB) in the governing mechanism resistance to paclitaxel using two lung adenocarcinoma cell lines with differing sensitivities.
