THE ACCELERATING JET OF 3C 279
2012
Analysis of the proper motions of the subparsec scale jet of the quasar 3C 279 at 15 GHz with the Very Long Baseline Array shows significant accelerations in four of nine superluminal features. Analysis of these motions is combined with the analysis of flux density light curves to constrain values of Lorentz factor and viewing angle (and their derivatives) for each component. The data for each of these components are consistent with significant changes to the Lorentz factor, viewing angle, and azimuthal angle, suggesting jet bending with changes in speed. We see that for these observed components Lorentz factors are in the range Γ = 10-41, viewing angles are in the range = 0.°1-5.°0, and in…
Lipoprotein apheresis for Lp(a)-hyperlipoproteinemia with progressive cardiovascular disease--Additional particular aspects of the Pro(a)LiFe multice…
2015
Lipoprotein apheresis (LA) can lower LDL-cholesterol and Lp(a) by 60%-70% and is the final escalating option in patients with hyperlipoproteinemias involving LDL or Lp(a) particles. Major therapeutic effect of LA is preventing cardiovascular events. In Germany since 2008 a reimbursement guideline has been implemented accepting to establish the indication for LA not only for familial or severe forms of hypercholesterolemia but also based on Lp(a)-hyperlipoproteinemia associated with a progressive course of cardiovascular disease, that persists despite effective treatment of other concomitant cardiovascular risk factors. The Pro(a)LiFe-study confirmed with a prospective multicenter design tha…
Homozygous Familial Hypercholesterolemia in Spain Prevalence and Phenotype-Genotype Relationship
2016
Background— Homozygous familial hypercholesterolemia (HoFH) is a rare disease characterized by elevated plasma levels of low-density lipoprotein cholesterol (LDL-C) and extremely high risk of premature atherosclerotic cardiovascular disease. HoFH is caused by mutations in several genes, including LDL receptor ( LDLR ), apolipoprotein B ( APOB ), proprotein convertase subtilisin/kexin type 9 ( PCSK9 ), and LDL protein receptor adaptor 1 ( LDLRAP1 ). No epidemiological studies have assessed HoFH prevalence or the clinical and molecular characteristics of this condition. Here, we aimed to characterize HoFH in Spain. Methods and Results— Data were collected from the Spanish Dyslipidemia Regist…
Effects of 5 MeV electron irradiation on deep traps and electroluminescence from near-UV InGaN/GaN single quantum well light-emitting diodes with and…
2020
The electrical properties, electroluminescence (EL) power output and deep trap spectra were studied before and after 5 MeV electron irradiation of near-UV single-quantum-well (SQW) light-emitting diodes (LED) structures differing by the presence or absence of InAlN superlattice underlayers (InAlN SL UL). The presence of the underlayer is found to remarkably increase the EL output power and the radiation tolerance of LEDs, which correlates with a much lower and more slowly changing density of deep traps in the QW region with radiation dose, and the higher lifetime of charge carriers, manifested by higher short-circuit current and open-circuit voltage in current–voltage characteristics under …
Antioxidant Therapy and Drugs Interfering with Lipid Metabolism: Could They Be Effective in NAFLD Patients?
2013
This review is part of a special issue dealing with various aspects of non-alcoholic fatty liver disease (NAFLD) and nonalcoholic steatohepatitis (NASH). We will focus on promising treatments of NASH with antioxidants and drugs that interfere with lipid metabolism.The other therapies of interest, such as diet, behavioral changes, and insulin sensitizers are presented elsewhere. Oxidative stress is believed to play a key role in the pathogenesis of NASH and other liver diseases. Antioxidants aimed at improving chronic alcoholic or viral liver diseases have been an object of study for some time. However, only a few high quality, randomized, versus placebo-controlled, double-blinded trials hav…
Evaluation of labial microvessels in Sjogren syndrome: A videocapillaroscopic study
2008
Summary Sjogren's syndrome (SS) is a chronic autoimmune rheumatic disease characterized by a progressive lymphocytic infiltration of exocrine glands, especially salivary and lachrymal ones, leading to xerostomia, parotid gland enlargement, and xerophtalmia. SS may occur alone (primary) or in association with almost any of the autoimmune rheumatic diseases (secondary), the most frequent being rheumatoid arthritis. The aim of this study is to describe the capillaroscopic pattern of the labial mucosa in patients with SS. Methods A total of 20 patients affected by SS and 20 healthy controls were examined. The patients with conditions that compromise microcirculation, such as diabetes, hypertens…
Ruddlesden-Popper Hybrid Lead Bromide Perovskite Nanosheets of Phase Pure n=2: Stabilized Colloids Stored in the Solid State.
2021
Ruddlesden-Popper lead halide perovskite (RP-LHP) nano-nanostructures can be regarded as self-assembled quantum wells or superlattices of 3D perovskites with an intrinsic quantum well thickness of a single or a few (n=2-4) lead halide layers; the quantum wells are separated by organic layers. They can be scaled down to a single quantum well dimension. Here, the preparation of highly (photo)chemical and colloidal stable hybrid LHP nanosheets (NSs) of ca. 7.4 μm lateral size and 2.5 nm quantum well height (thereby presenting a deep blue emission at ca. 440 nm), is reported for the first time. The NSs are close-lying and they even interconnect when deposited on a substrate. Their synthesis is …
Electrothermal Atomic Absorption Spectrometric Diagnosis of Familial Hypercholesterolemia
2000
We have developed a new nonradioactive assay to identify human low-density lipoprotein receptor defects. It is based on the incubation of cultured cells with colloidal gold-LDL conjugates and quantitation of the gold associated with the cells by electrothermal atomic absorption spectrometry. After an oxidative treatment with nitric and hydrochloric acids, the biological matrix interferes neither with the gold recovery nor with the gold measurements, which are linear, at least from 0.15 to 3 ng of gold. When cells expressing a functional LDL receptor are incubated with increasing amounts of colloidal-gold LDL conjugates, the obtained saturation curve parallels that described when [125I]LDL i…
