Evaluation of Electronic-Ionic Transport Properties of a Mg/Zr-Modified LiNiMnO Cathode for Li-Ion Batteries.

There is an enormous drive for moving toward cathode material research in LIBs due to the proposal of zero-emission electric vehicles together with the restriction of cathode materials in design. LiNiMnO (LNMO) attracts great research interests as high-voltage Co-free cathodes in LIBs. However, a more extensive study is required for LNMO due to its poor electrochemical performance, especially at high temperature, because of the instability of the LNMO interface.

Biphasic P2/O3-NaLiMnFeO: a structural investigation.

The P2/O3 layered oxide system is thought to benefit from a synergistic enhancement, resulting from the presence of both phases, which makes it a promising cathode material for Na-ion battery applications. Here, biphasic P2/O3-NaLiMnFeO is investigated via a combination of neutron and X-ray scattering techniques. Neutron diffraction data indicates that the O3 alkali metal site is fully occupied by Li.

Toward Stable Electrode/Electrolyte Interface of P2-Layered Oxide for Rechargeable Na-Ion Batteries.

The electrochemical properties of P2-NaMnFeTiO layered oxide, which is a promising cathode material for rechargeable Na-ion batteries (NIBs), are evaluated with an optimized in-house ionic liquid (IL)-based electrolyte, and its performance is compared with that using carbonate-based electrolyte. The IL-based system reveals better electrochemical performance at room temperature than the carbonate electrolyte-based one at 0.1C and 1C, especially in terms of cycling stability, with a 97% capacity retention after 100 deep cycles (0.

Eritema anular eosinofílico en un adulto Eosinophilic anular erythema in an adult.

Eosinophilic annular erythema (EAE) is an uncommon eosinophilic dermatosis. Clinically it is characterized by recurrent episodes of annular or figurative plaques. The histopathological study shows a perivascular inflammatory infiltrate in the superficial and deep dermis, composed of lymphocytes and eosinophils.

Synthesis and characterization of NaNiF3·3H2O: an unusual ordered variant of the ReO3 type.

A new hydrated sodium nickel fluoride with nominal composition NaNiF3·3H2O was synthesized using an aqueous solution route. Its structure was solved by means of ab initio methods from powder X-ray diffraction and neutron diffraction data. NaNiF3·3H2O crystallizes in the cubic crystal system, space group Pn3̅ with a = 7.

Clinicopathologic correlations of renal microthrombosis and inflammatory markers in proliferative lupus nephritis.

Introduction: Microthrombosis is often observed in lupus nephritis (LN) lesions, but its clinical significance is unknown. We evaluated the clinicopathologic correlations of renal microthrombosis and inflammatory markers in LN.

Methods: Kidney biopsies from 58 patients with systemic lupus erythematosus (SLE) proliferative nephritis were analyzed with immunohistochemistry (IHC) for intravascular platelet aggregates (CD61), macrophagic infiltration (CD68), and activated complement deposition (C4d).

The transcriptional response of normal and rheumatoid arthritis synovial fibroblasts to hypoxia.

Objective: Hypoxia is a prominent feature in rheumatoid arthritis (RA) synovium. However, its contribution to the pathogenesis of RA remains unclear. We undertook this study to systematically characterize the changes in gene expression induced by hypoxia in synovial fibroblasts.

Immunohistochemical detection of intravascular platelet microthrombi in patients with lupus nephritis and anti-phospholipid antibodies.

Objectives: To evaluate whether the use of platelet immunohistochemistry (IHC) markers improves the sensitivity of histological methods to detect microthrombosis in SLE nephritis and aPLs and to analyse the clinicopathological correlations of microthrombosis in this setting.

Methods: Kidney biopsy specimens from 65 patients with SLE, including 36 with positive aPLs, were studied by IHC using antibodies against platelet glycoproteins CD41 and CD61. Clinical data at the time of kidney biopsy and during a mean follow-up of 7.

[Health among the elderly].

We explore gender, class and geographical inequalities in health of the population aged over 65 years in Spain. We gathered data from the 1997 National Health Survey, 1999 hospital discharge data, 1998 mortality data from vital statistics, and from the 1999 National Survey on Disabilities. Health related behaviors (tobacco and alcohol consumption, eating disorders and physical activity), self-rated health, chronic health problems, functional capacity, and health service utilization are described by gender and social class.
