A randomised controlled study on the use of anti-inflammatory drugs in patients with cancer pain on morphine therapy: effects on dose-escalation and …
2002
The role of non-steroidal anti-inflammatory drugs (NSAIDs) in cancer pain has been well established in the treatment of mild pain and in association with opioids in the treatment of moderate to severe pain. The aim of this study was to verify the effects of NSAIDs on morphine escalation in advanced cancer patients with pain followed-up at home and to assess the pharmacoeconomic implications. A prospective randomised controlled study was carried out in 156 consecutive advanced cancer patients with pain followed-up at home in the period December 1999-December 2000. In this group of patients, 47 were selected with pain progression after 1 week of opioid stabilisation. Patients were randomly as…
Randomized Phase II trial assessing estramustine and vinblastine combination chemotherapy vs estramustine alone in patients with progressive hormone-…
2004
Abstract Based on the results of combined data from three North American Phase II studies, a randomised Phase II study in the same patient population was performed, using combination chemotherapy with estramustine phosphate (EMP) and vinblastine (VBL) in hormone refractory prostate cancer patients. In all, 92 patients were randomised into a Phase II study of oral EMP (10 mg kg day continuously) or oral EMP in combination with intravenous VBL (4 mg m(2) week for 6 weeks, followed by 2 weeks rest). The end points were toxicity and PSA response in both groups, with the option to continue the trial as a Phase III study with time to progression and survival as end points, if sufficient responses…
The Immune Checkpoint Molecule CD200 Is Associated with Tumor Grading and Metastasis in Bladder Cancer.
2018
BACKGROUND We examined the expression of CD200, a ligand of immune tolerance, in transitional cell carcinoma of the human bladder (TCC). MATERIALS AND METHODS CD200 was analyzed by immunohistochemistry (IHC) in 90 patients with suspected TCC lesions of the bladder. Expression of CD200 was exemplarily validated by quantitative reverse transcription polymerase chain reaction and western blot analysis. RESULTS CD200 was detectable at mRNA and protein levels in TCC homogenate and TCC cell lines (T24, UMUC3). TCC tissues showed significantly higher CD200 expression (p<0.005) than normal bladder tissues. CD200 signals were also higher in metastasized compared to localized TCC (p<0.05). CD200 was …
The Higher the Dose, the Greater the Sex Differences in Escape–Avoidance Response in Mice After Acute Administration of Haloperidol
1998
Abstract MONLEON, S. AND A. PARRA. The higher the dose, the greater the sex differences in escape–avoidance response in mice after acute administration of haloperidol . PHARMACOL BIOCHEM BEHAV 60 (1) 279–284, 1998.—Sex differences in the effects of haloperidol in the escape–avoidance response have previously been found in various studies carried out in our laboratory in which mice were used as experimental subjects. Males were more affected than females by the disruptive effects of this neuroleptic of frequent clinical use. In the present work these sex differences were evaluated in a unique training session using several doses of the drug (0.075, 0.25, and 0.75 mg/kg IP). The number of avo…
Gender differences in escape-avoidance behavior of mice after haloperidol administration.
1993
Gender differences in the disruptive effects of haloperidol on some reinforced behaviors have been observed in different species. However, the inhibitory action of haloperidol on the acquisition and performance of escape-avoidance behavior has only been investigated in male subjects. The present experiment was designed to investigate possible gender differences in the effects of haloperidol on the initial phase of an escape-avoidance learning task. Male and female mice of the OF1 strain were given a single training session in a shuttle-box. Thirty minutes prior to the behavioral test, mice were injected IP with haloperidol (0.25 mg/kg) or physiological saline (10 ml/kg). Latencies of escape…
Postnatal increases in axonal conduction velocity of an identified Drosophila interneuron require fast sodium, L-type calcium and shaker potassium ch…
2019
Abstract During early postnatal life, speed up of signal propagation through many central and peripheral neurons has been associated with an increase in axon diameter or/and myelination. Especially in unmyelinated axons postnatal adjustments of axonal membrane conductances is potentially a third mechanism but solid evidence is lacking. Here, we show that axonal action potential (AP) conduction velocity in the Drosophila giant fiber (GF) interneuron, which is required for fast long-distance signal conduction through the escape circuit, is increased by 80% during the first day of adult life. Genetic manipulations indicate that this postnatal increase in AP conduction velocity in the unmyelina…
Long-term efficacy of botulinum toxin A for treatment of blepharospasm,hemifacial spasm, and spastic entropion: a multicentre study using two drug-do…
2009
PURPOSE: To investigate the long-term effectiveness and safety of botulinum neurotoxin A (BoNT-A) treatment in patients with blepharospasm (BEB), hemifacial spasm (HFS), and entropion (EN) and to use for the first time two modified indexes, 'botulin toxin escalation index-U' (BEI-U) and 'botulin toxin escalation index percentage' (BEI-%), in the dose-escalation evaluation. METHODS: All patients in this multicentre study were followed for at least 10 years and main outcomes were clinical efficacy, duration of relief, BEI-U and BEI-%, and frequency of adverse events. RESULTS: BEB, HFS, and EN patients received a mean BoNT-A dose with a significant inter-group difference (P<0.0005, respectivel…
The assessment of lifestyle changes during the COVID-19 pandemic using a multidimensional scale
2020
Introduction Healthy lifestyles are relevant to several diseases and to maintain individuals’ mental health. Exposure to epidemics and confinement have been consistently associated with psychological consequences, but changes on lifestyle behaviours remain under-researched. Materials and Methods An online survey was conducted among the general population living in Spain during the COVID-19 home-isolation. In addition to demographic and clinical data, participants self-reported changes in seven lifestyle domains. The Short Multidimensional Inventory Lifestyle Evaluation was developed specifically to evaluate changes during the confinement (SMILE-C). Results A total of 1254 individuals comple…
Cancer cells induce immune escape via glycocalyx changes controlled by the telomeric protein TRF2
2019
International audience; Myeloid-derived suppressor cells (MDSCs) are immature myeloid cells with strong immunosuppressive activity that promote tumor growth. In this study, we describe a mechanism by which cancer cells control MDSCs in human cancers by upregulating TRF2, a protein required for telomere stability. Specifically, we showed that the TRF2 upregulation in cancer cells has extratelomeric roles in activating the expression of a network of genes involved in the biosynthesis of heparan sulfate proteoglycan, leading to profound changes in glycocalyx length and stiffness, as revealed by atomic force microscopy. This TRF2-dependent regulation facilitated the recruitment of MDSCs, their …
Morphine potentiates the impairing effects of neuroleptics on two-way active conditioned avoidance response in male mice
2004
The dopaminergic and opioid systems have effects on the conditioned avoidance response (CAR), although the possible interaction between these systems on this behaviour has not been studied. The effects of morphine (12.6 mg/kg), haloperidol (0.075 mg/kg), sulpiride (20 mg/kg) and risperidone (0.1 mg/kg) alone as well as morphine combined with these dopamine (DA) antagonists on the acquisition and performance of the CAR were explored in mice. Morphine increased avoidances but this seemed secondary to a rise in activity levels. All DA antagonists impaired CAR in the acquisition phase but only haloperidol disrupted performance. The combination of morphine plus neuroleptics impaired acquisition …
