Nonalcoholic fatty liver disease is an increasingly recognized condition that may progress to end-stage disease. We investigated the effects of weight reduction and ursodeoxycholic acid administration in patients with this disease.A double-blind, placebo-controlled trial. Twenty-seven women a body mass index >30 kg/m2 willing participate diet plan for six weeks were studied assigned one two treatment groups (ursodeoxycholic acid, n = 14: placebo 13). Both received normal (1,200 kcal/d) plus...

We have previously observed that UCB binds to ZnSO4in vitro, and suppresed the biliary bilirubin secretion in hamster. The aim of this study was designed investigate whether Zn salts might inhibit enterohepatic cycling subjects with Gilbert´s syndrome. Fifteen patients syndrome 5 normal healthy volunteers were included according following criteria: fasting hyperbilirubinemia, no hemolysis, free any medication. Patients randomly assigned receive acute o chronic treatment. Subjects treated...

In this work, a non-intrusive, spatially resolved, spectro-tomographic optical diagnostic of the electronic density and temperature on linear plasma column Mistral is presented. Coupling spectroscopy tomography technique gives access to local light emission at different wavelengths (visible near IR) in an argon plasma. Taking advantage symmetry experiment, results are validated found correspond corona equilibrium state. With use another spectrometer Langmuir probe, we propose non-intrusive...

The aim of this study is to evaluate the results obtained on optical bench and clinically with an isofocal lens (ISOPure, BVI medical, Belgium) compare them a standard monofocal one (MicroPure, Belgium). To do so, we have combined laboratory investigation prospective, comparative, randomized clinical study. First, measured wavefront two models studied using NIMO TR1504 (Lambda-X, deflectometer for three nominal powers: +10.00, +20.00 +30.00 D. In 48 patients, half implanted ISOPure other...

In this work, we present Doppler free two photon optogalvanic measurements to determine the local electric field strength (E-field) in cathode fall region of a hollow discharge, operated pure hydrogen, via Stark splitting 2S level hydrogen. The main aim article is comparison made with different materials, stainless steel, and tungsten; both them are widely used low-pressure discharges. Sputtering steel principle cause differences observed for E-field variation, analyzed frame sputtered...

Abstract Purpose MB02 is a biosimilar to bevacizumab that has demonstrated similar physicochemical and functional properties in vitro studies the reference (Avastin ® ). This study aims assess pharmacokinetic (PK) similarity of Japanese population. Methods double-blind, randomized, parallel-group, single-dose PK study, was performed healthy male volunteers. Subjects were equally randomized (1:1) receive single (3 mg/kg) IV dose or bevacizumab. assessments done up 70 days post-dose....

The COVID pandemic is forcing the renewal of scientific conferences, offering opportunities to introduce technological and inclusive developments. Our analysis focuses on implementation practices for female early-career researchers in a virtual conference. This organization approach was applied XIII Spanish Optical Meeting (RNO2021), which also characterized by avatars interacting an online metaverse. effectiveness policies novel tools evaluated using participation data post-conference...

In this work, Doppler-free two photon optogalvanic spectroscopy is used to measure the electric field strength in cathode fall region of a hollow discharge, operated pure hydrogen, via Stark splitting 2S level atomic hydrogen. The characteristics are analysed for various pressures and wide range discharge currents. Tungsten as material, because it allows reliable measurements fairly conditions its minimal sputtering. Two diameters (10 mm 15 mm) study dependence on geometry. reveal that quite...

Doppler-free two photon optogalvanic spectroscopy was employed in extensive studies to measure the electric field strength cathode fall region of a hollow discharge (HCD), operated pure hydrogen, via Stark splitting 2S level atomic hydrogen. The high quality measurements, based on an improved design and laser spectroscopic set-up, reveal clear differences recorded spectra obtained for different material (stainless steel tungsten) at otherwise identical conditions. It is well known, that...

Unconscious perceptions and decisions are influenced by gender bias. In this work, we provide an exhaustive data analysis of the Ph.D. theses defended in field optics photonics Spain filtering key descriptors gender. Our results show a severe underrepresentation women stage community, which becomes even more prominent technological theoretical domains. The gap is reduced biomedical visual optics. This asymmetry symptom bias science associated with traditional stereotypes about health social...

Stark widths of 32 OII spectral lines have been measured, for the first time in 16 cases to authors' knowledge.A pulsed arc was used as a plasma source.The electron density, determined both interferometrically and spectroscopically, covers range (2.5-7.5)10 22m -3 .The temperature, from Boltzmannplots, 25000 -47000 K. Possible dependencies width on temperature checked.The measured are compared with theoretical experimental data available literature.

Since its first description at the beginning of 19th century, greater awareness this disorder has been achieved, becoming nowadays a recognized but sometimes underdiagnosed cause ischemic stroke in childhood. AIM. To describe population children with cerebral venous thrombosis, analyzing clinical presentation, risk factors, treatment and evolution.A descriptive, retrospective longitudinal review from 0 to 17 years age diagnosed sinovenous thrombosis was conducted, during period time between...

The aim of this work was to compare an enhanced monofocal (RayOne EMV RAO200E, Rayner) and standard RAO600C Aspheric, intraocular lenses (IOLs) for three nominal powers (+10.00 D, +20.00 D +30.00 D) as a function the optical aperture diameter (pupil diameter) using commercial Schlieren phase-shifting deflectometer NIMO TR1504 (Lambda-X, Belgium).
