Ethanol is often used in sclerotherapy to treat vascular malformations. Nerve injury is a known complication of this procedure. However, the management of this complication is not well described in literature. This case describes a 10-year-old boy with a slow flow vascular malformation in the right calf who underwent transarterial ...

Monocyte-derived macrophages play a key role in atherogenesis because their transformation into foam cells is responsible for deposition of lipids in plaques within arterial walls. The appearance of cytosolic lipid droplets is a hallmark of macrophage foam cell formation and the molecular basics involved in this process are not well-understood. ...

The Tinto River (Huelva, Spain) is a natural acidic rock drainage environment produced by the bio-oxidation of metallic sulfides from the Iberian Pyritic Belt. A geomicrobiological model of the different microbial cycles operating in the sediments was recently developed through molecular biological methods, suggesting the presence of iron reducers, methanogens, ...

This paper presents a new method to detect and to delineate phonocardiogram (PCG) sounds. Toward this objective, after preprocessing the PCG signal, two windows were moved on the preprocessed signal, and in each analysis window, two frequency-and amplitude-based features were calculated from the excerpted segment. Then, a synthetic decision making ...

PURPOSE: Cyclosporine (CsA) is often prescribed to patients with glucocorticoid (GC)-dependent nephrotic syndrome. Although it is well known that long-term administration of GC causes osteoporosis, the effects of CsA on bone metabolism are not fully established. Therefore, we examined the effects of CsA on bone metabolism in patients with GC-dependent ...

BACKGROUND: There is evidence that small-for-size liver grafts are more vulnerable to ischemia/reperfusion injury after liver transplantation. We hypothesized that ischemic injury is more pronounced in small liver remnants after major hepatectomies. METHODS: Fifteen patients underwent extended hepatectomy with remnant liver mass less than 30 % of standard liver weight (study ...

In this paper, an insect biofuel cell (BFC) using trehalose included in insect hemolymph was developed. The insect BFC is based on trehalase and glucose oxidase (GOD) reaction systems which oxidize β-glucose obtained by hydrolyzing trehalose. First, we confirmed by LC-MS that a sufficient amount of trehalose was present in ...

PURPOSE: Patients with Stargardt's disease usually have a poor visual prognosis. However, in our clinical practice we have observed some patients with dark-red foveal pigmentation (sparing) who had good best corrected visual acuity (BCVA) despite the presence of a late-stage disease. The purpose of this study was to investigate the ...

Because their ability to greatly enhance the low natural peroxidase activity of hemin, G-quadruplex-based DNAzymes have been widely used as an alternative to peroxidases for many colorimetric, chemiluminescent, or visual detections of metal ions, small molecules, nucleic acids, proteins, and cancer cells. To obtain G-quadruplex-based DNAzymes with better peroxidase activity, ...

A two-stage bioreactor was operated for a period of 140 days in order to develop a post-treatment process based on anaerobic bioxidation of sulfite. This process was designed for simultaneously treating the effluent and biogas of a full-scale UASB reactor, containing significant concentrations of NH(4) and H(2)S, respectively. The system comprised ...

Previous studies have shown that craniofacial bone marrow stromal cells (BMSCs) have a strong osteogenic potential. However, the mechanism by which BMSCs of various embryonic origins develop diverse osteogenic potentials remains unclear. To investigate the mechanisms regulating osteoblast differentiation in two different types of BMSCs, we compared the temporal and ...

Although cholesterol has been involved in the pathophysiology of Alzheimer disease (AD), its distribution in the cerebral cortex over the course of AD is unknown. We describe an original method to quantify cholesterol distribution using time-of-flight secondary ion mass spectrometry imaging. Cholesterol was unevenly distributed along the cortical thickness, being ...

Electron mobility within iron (oxyhydr)oxides enables charge transfer between widely separated surface sites. There is increasing evidence that this internal conduction influences the rates of interfacial reactions and the outcomes of redox-driven phase transformations of environmental interest. To determine the links between crystal structure and charge-transport efficiency, we used pump-probe ...

Increasing evidences show that inhalation of indoor bioaerosols has caused numerous adverse health effects and diseases. However, the bioaerosol size distribution, composition, and concentration level, representing different inhalation risks, could vary with different living environments. The six-stage Andersen sampler is designed to simulate the sampling of different human lung regions. ...

We consider the inverse problem of continuum mechanics with the tissue deformation described by a mixed displacement-pressure finite element formulation. The mixed formulation is used to model nearly incompressible materials by simultaneously solving for both elasticity and pressure distributions. To improve numerical conditioning, a common solution to this problem is ...

Obstructive sleep apnea (OSA) is commonly diagnosed based on the apnea-hypopnea index (AHI). Presently, novel indices were introduced for sleep apnea severity: total duration of sleep apnea and hypopnea events (TAHD%) and a combined index including duration and severity of the events (TAHD% × average desaturation). Two hundred and sixty-seven ...

In this article, we will introduce interpersonal psychotherapy as an effective short-term treatment strategy in major depression. In IPT, a reciprocal relationship between interpersonal problems and depressive symptoms is regarded as important in the onset and as a maintaining factor of depressive disorders. Therefore, interpersonal problems are the main therapeutic ...
