We have investigated multiphoton multiple ionization dynamics of xenon atoms using a new x-ray free-electron laser facility, SPring-8 Angstrom Compact free electron LAser (SACLA) in Japan, and identified that Xen+ with n up to 26 is produced at a photon energy of 5.5 keV. The observed high charge states (n >= 24) are produced via five-photon absorption, evidencing the occurrence of multiphoton abs

Intrastriatal transplantation of dopaminergic neurons can restore striatal dopamine levels and improve parkinsonian deficits, but the mechanisms underlying these effects are poorly understood. Here, we show that transplants of dopamine neurons partially restore activity-dependent synaptic plasticity in the host striatal neurons. We evaluated synaptic plasticity in regions distal or proximal to the

AIM: The etiology of abdominal aortic aneurysm (AAA) includes inflammation, coagulation, and endothelial dysfunction. We have prospectively evaluated relations between these mechanisms and AAA growth. Tumour necrosis factor (TNF)-α, interleukin (IL)-6, endothelin (ET)-1, CD40 ligand and the complex formed between activated protein C (APC) and protein C inhibitor (PCI) were measured annually and re

The aim of this study was to investigate if future thinking would change following two forms of Internet-delivered cognitive behavior therapy (ICBT) for major depression. A second aim was to study the association between pre-post changes in future thinking and pre-post changes in depressive symptoms. Effects of psychological treatments are most often tested with self-report inventories and seldom

Atomically precise graphene nanoribbons (GNRs) can be fabricated via thermally induced polymerization of halogen containing molecular precursors on metal surfaces. In this paper the effect of substrate reactivity on the growth and structure of armchair GNRs (AGNRs) grown on inert Au(111) and active Cu(111) surfaces has been systematically studied by a combination of core-level X-ray spectroscopies

This study investigated the human gastrointestinal uptake (f1) and subsequent whole-body retention of orally administered inorganic radioactive cobalt. Of eight adult volunteers aged between 24 and 68 years, seven were given solutions of (57)Co (T1/2 = 272 d) containing a stable cobalt carrier, and six were given carrier-free (58)Co (T1/2 = 71 d). The administered activities ranged between 25 and

To explore the impact of the sociocultural care and service context on dependence in instrumental activities of daily living, data were collected with 1448 very old women in 5 European countries. In addition, the influence of socioeconomic indicators was explored, using descriptive statistics and regression analyses. Highly significant differences concerning formal/informal support and use of mobi

Pseudomonas aeruginosa is a pathogen that frequently colonizes patients with cystic fibrosis (CF) or chronic obstructive pulmonary disease (COPD). Several pathogens are known to bind vitronectin to increase their virulence. Vitronectin has been shown to enhance P. aeruginosa adhesion to host epithelial cells.

The common backswimmer, Notonecta glauca, uses vision by day and night for functions such as underwater prey animal capture and flight in search of new habitats. Although previous studies have identified some of the physiological mechanisms facilitating such flexibility in the animal's vision, neither the biophysics of Notonecta photoreceptors nor possible cellular adaptations are known. Here, we

OBJECTIVE: The increasing number of negative trials for ovarian cancer treatment has prompted an evaluation of new biologic agents, which in combination with chemotherapy may improve survival. The aim of this study was to investigate the response rate in platinum-resistant, KRAS wild-type ovarian cancer patients treated with pegylated liposomal doxorubicin (PLD) supplemented with panitumumab. PATI

Background: Dementia with Lewy bodies (DLB) accounts for 15-20%, of the millions of people worldwide with dementia. Accurate diagnosis is essential to avoid harm and optimize clinical management. There is therefore an urgent need to identify reliable biomarkers. Methods: Mass spectrometry was used to determine the specificity of antibody alpha-synuclein (211) for alpha-synuclein. Using gel electro

Cellobiose dehydrogenase (CDH) is a monomeric extracellular flavocytochrome composed of a catalytic dehydrogenase domain (DHCDH) containing flavin adenine dinucleotide (FAD), a cytochrome domain (CYTCDH) containing heme b, and a linker region connecting the two domains. In this work, the effect of deglycosylation on the electrochemical properties of CDH from Phanerochaete chrysosporium (PcCDH) and

In this study, five different flexible osmium based redox polymers were investigated for their ability to efficiently "wire" the oxidoreductase pyranose dehydrogenase (PDH, EC 1.1.99.29) from Agaricus meleagris, on graphite electrodes for possible applications in biofuel cells. A series of newly synthesised osmium based redox polymers covering the potential range between -270 and +160mV vs. Ag|AgC

Global climate models simulate the Earth's climate impressively at scales of continents and greater. At these scales, large-scale dynamics and physics largely define the climate. At spatial scales relevant to policy makers, and to impacts and adaptation, many other processes may affect regional and local climate and perhaps trigger teleconnections that provide significant feedbacks on the global c

A series of molecularly imprinted polymer nanoparticles have been synthesized employing various template/functional monomer/crosslinking monomer ratio and characterized in detail to elucidate the correlation between the synthetic conditions used and the properties (e.g., particle size and template binding properties) of the obtained nanoparticles. In brief, the presence of propranolol (template) i

(PRELP)-P-hbd is a peptide corresponding to the N-terminal heparin binding domain of the matrix protein proline/arginine-rich end leucine-rich repeat protein (PRELP). (PRELP)-P-hbd inhibits osteoclastogenesis entering pre-fusion osteoclasts through a chondroitin sulfate- and annexin 2-dependent mechanism and reducing the nuclear factor-B transcription factor activity. In this work, we hypothesized

The pathophysiology of sepsis-associated encephalopathy (SAE) is complex and remains incompletely elucidated. Dysregulated reactive oxygen species (ROS) production and mitochondrial-mediated necrotic-apoptotic pathway have been proposed as part of the pathogenesis. The present study aimed at analyzing the preventive effect of the free radical scavenger edaravone on sepsis-induced brain alterations

Time-resolved dual-broadband picosecond pure rotational CARS has been applied to measure self-broadened S-branch N-2-N-2 Raman linewidths in the temperature range 294-1466 K. The coherence decays were detected directly in the time domain by following the J-dependent CARS signal decay as a function of probe delay. The rotational Raman N-2-N-2 linewidths were derived from these time-dependent decays

BACKGROUND: The need for equivalent results of routine measurement procedures for the alcohol biomarker carbohydrate-deficient transferrin (CDT) has been recognized by the IFCC. This article describes a project to harmonize CDT as conducted by an IFCC working group initiated for this purpose. METHODS: We used procedures for achieving harmonization as developed by the Consortium for Harmonization o
