Effects of typical inducers on olfactory xenobiotic-metabolizing enzyme, transporter, and transcription factor expression in rats.

2010

International audience; Several xenobiotic-metabolizing enzymes (XMEs) have been identified in the olfactory mucosa (OM) of mammals. However, the molecular mechanisms underlying the regulation of these enzymes have been little explored. In particular, information on the expression of the transcriptional factors in this tissue is quite limited. The aim of the present study was to examine the impact of five typical inducers, Aroclor 1254, 3-methylcholanthrene, dexamethasone, phenobarbital, and ethoxyquin, on the activities and mRNA expression of several XMEs in the OM and in the liver of rats. We also evaluated the effects of these treatments on the mRNA expression of transcription factors an…

Treatment of hepatocellular carcinoma: A systematic review of randomized controlled trials

1997

Summary Background Hepatocellular carcinoma (HCC) is a leading cause of cancer-related death. Many treatments have been proposed but considerable uncertainty still remains about their effectiveness. In this review we evaluated the quality, clinical coherence, consistency and results of Randomized Controlled Trials (RCT) of non-surgical treatments for HCC. Methods Thirty-seven RCTs examining the effect of different treatments were retrieved using MEDLINE (November 1978 to December 1995) and a review of reference lists. Selected aspects of the quality of design, conduct and reporting were examined. The odds ratio for the probability of surviving up to one year was calculated according to the …

Lower Urinary Tract Symptoms: What's New in Medical Treatment?

2018

Abstract Context Pharmacological treatment is a cornerstone in the management of patients with lower urinary tract symptoms (LUTS). Objective To review emerging evidence in the medical treatment of LUTS. Evidence acquisition An Embase/Pubmed-based literature search was conducted in December 2017, screening for randomized controlled trials (RCTs), prospective and retrospective series, animal model studies, and reviews on medical treatment of LUTS. Evidence synthesis The main medical innovation in recent years in overactive bladder (OAB) has been the approval of the first β 3 -adrenoceptor agonists (mirabegron) and intradetrusor onabotulinum toxin A, while several other drugs such as antiepil…

Optimization of two-step techniques engineered for the preparation of polyamide 6 graphene oxide nanocomposites

2019

Abstract Different processing conditions to achieve polyamide 6 (PA6)-graphene oxide (GO) nanocomposites were investigated. GO was pre-dispersed in PA6 by three different solvent-based methods and, further, melt processed to prepare nanocomposites at two different loading levels, namely 2 and 5 wt.%. The evolution of rheological and mechanical properties was analyzed by investigating eventual changes in the microstructure and polymer crystallinity, aiming at providing a detailed processing-structure-properties relationship for these systems.

On the blue phase structure of hydrogen-bonded liquid crystals via 19F NMR

2018

Abstract 19 F NMR spectra are simulated for blue phase I of FPHG( St 1.5 ∗ Ap 1.5 ) based on a model of a double-twisted substructure inside cylinders that form a body-centred cubic lattice. A kinetic matrix is included to describe jump processes over quarter pitch lengths. Though the lines in the NMR spectra are broad and featureless, changes in the widths and positions with temperature are well described by the blue phase model structure. The spectra in the chiral nematic N∗ phase are also simulated. Dynamics in the BP I are found to be slower than in the N∗ phase.

Single-Element Reflective Digital Holographic Microscopy

2021

Digital holographic microscopy (DHM) is a well-known microscopy technique using an interferometric architecture for quantitative phase imaging (QPI) and it has been already implemented utilizing a large number of interferometers. Among them, single-element interferometers are of particular interest due to its simplicity, stability, and low cost. Here, we present an extremely simple common-path interferometric layout based on the use of a single one-dimensional diffraction grating for both illuminating the sample in reflection and generating the digital holograms. The technique, named single-element reflective digital holographic microscopy (SER-DHM), enables QPI and topography analysis of r…

L’occupation du Néolithique final de Trémonteix (Puy-de-Dôme) et ses assemblages de mobilier

2020

In the heart of Auvergne (Puy-de-Dôme), the Late Neolithic settlement of Trémonteix is established beneath the Côtes de Clermont-Ferrand, a vast basalt plateau that dominates the north of the actual agglomeration. Within the framework of a rescue archaeology, an excavation conducted by Inrap, over 2588 m2 and has delivered several features and revealed a number of terraced constructions, dug into the bank of an ancient river bed. These are sheltered spaces (building 1) and artisanal activity zones, documented by pits and remains of occupation levels that were rich in finds. These constructions provided various pottery types, worked flint, an abundance of mainly domestic animal remains, work…

Minimally invasive secondary cytoreduction plus HIPEC for recurrent ovarian cancer: a case series.

2014

Objective To analyze the feasibility of laparoscopic/robotic secondary cytoreductive surgery and hyperthermic intraperitoneal intra-operative chemotherapy (SCS + HIPEC) in a retrospective series of isolated platinum sensitive recurrent ovarian cancer. Methods We retrospectively evaluated a consecutive series of ovarian cancer patients with isolated platinum sensitive relapse. Isolated relapse was defined as the presence of a single nodule, in a single anatomic site. In all cases the presence of isolated relapse was assessed at pre-operative FDG-PET/CT scan, and confirmed with staging laparoscopy performed immediately before SCS + HIPEC. Results 84 women with platinum sensitive relapse recei…
