Recent progress in scanning electron microscopy for the characterization of fine structural details of nano materials

Research concerning nano-materials (metal-organic frameworks (MOFs), zeolites, mesoporous silicas, etc.) and the nano-scale, including potential barriers for the particulates to diffusion to/from is of increasing importance to the understanding of the catalytic utility of porous materials when combined with any potential super structures (such as hierarchically porous materials). However, it is di

Targeting CD162 protects against streptococcal M1 protein-evoked neutrophil recruitment and lung injury

Streptococcus pyogenes of the M1 serotype can cause streptococcal toxic shock syndrome and acute lung damage. CD162 is an adhesion molecule that has been reported to mediate neutrophil recruitment in acute inflammatory reactions. In this study, the purpose was to investigate the role of CD162 in M1 protein-provoked lung injury. Male C57BL/6 mice were treated with monoclonal antibody directed again

Multimodal approach to assess tumour vasculature and potential treatment effect with DCE-US and DCE-MRI quantification in CWR22 prostate tumour xenografts.

The aim of this study was to compare intratumoural heterogeneity and longitudinal changes assessed by dynamic contrast-enhanced ultrasound (DCE-US) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in prostate tumour xenografts. In vivo DCE-US and DCE-MRI were obtained 24 h pre- (day 0) and post- (day 2) radiation treatment with a single dose of 7.5 Gy. Characterization of the tum

Impact of Organized Sports on Activity, Participation, and Quality of Life in People With Neurologic Disabilities.

Physical activity and exercise is the mainstay of chronic disease prevention and health maintenance for all people with and without a disability, and clear evidence exists of the benefits among various populations with neurologic disabilities. However, the potential benefits of organized sports for people with neurologic disabilities are not as well explored. In this narrative review, current evid

Vascular events are risk factors for anal incontinence in systemic sclerosis: a study of morphology and functional properties measured by anal endosonography and manometry.

Objectives: To study anal sphincter morphology, anal sphincter pressure, and rectoanal inhibitory reflex (RAIR) in patients with systemic sclerosis (SSc) complicated by anal incontinence (AI) and to investigate possible risk factors for AI in SSc. Method: Nineteen SSc patients with severe AI were investigated using anal endosonography, anal manometry, and rectal manovolumetry. To determine risk fa

New Insights into the Carrier-Mediated Transport of Estrone-3-sulfate in the Caco-2 Cell Model

The current studies were undertaken to gain new insights into the interplay and mechanism of membrane transporters involved in the permeability of estrone-3-sulfate (E1S) in Caco-2 cells cultured either on the bottom of multiwell plastic dishes or on filter support. We demonstrate that Caco-2 cells from the "Deutsche sammlung von mikroorganismen und zellkulturen" (DSMZ) exhibit extensive and consi

Metaplastic columnar mucosa in the cervical esophagus after esophagectomy.

OBJECTIVE: To evaluate the pathogenesis of metaplastic processes within the esophagus using a human model in which the exact duration of reflux was known. SUMMARY BACKGROUND DATA: The pathogenesis of Barrett's esophagus (BE) is incompletely understood. Patients undergoing esophagectomy and gastric tube reconstruction represent a good model for studying the pathophysiology of columnar cell metaplas

The conodont fauna in the middle ordovician Eoplacognathus pseudoplanus Zone of Baltoscandia

Conodont faunas from the Eoplacognathus pseudoplanus Zone in five main areas of Middle Ordovician rocks in Sweden are described and discussed and compared with faunas of comparable age from neighbouring areas. The investigation is based on 118 samples which together yielded 175 114 conodont elements. The Swedish conodont faunas are intermediate between shallower-water faunas from the eastern part

Core excitation in O-3 localized to one of two symmetry-equivalent chemical bonds: Molecular alignment through vibronic coupling

Core excitation from terminal oxygen O-T in O-3 is shown to be an excitation from a localized core orbital to a localized valence orbital. The valence orbital is localized to one of the two equivalent chemical bonds. We experimentally demonstrate this with the Auger-Doppler effect which is observable when O-3 is core excited to the highly dissociative O(T)1S(-)17a(1)(1) state. Auger electrons emit

All-diode-laser ultraviolet absorption spectroscopy for sulfur dioxide detection

Ultraviolet radiation around 302 nm was produced by sum-frequency generation in beta-barium borate employing a blue and a near-infrared diode laser. The diode-laser-based spectrometer has a mode-hop-free tuning range of 50 GHz and was used for high-resolution spectroscopic detection of sulfur dioxide. Differential measurements of several gas concentrations, at low pressure as well as at ambient at

The influence of the T-stress on the directional stability of cracks

The sign of the T-stress has been widely used for deciding whether directional stability prevails for straight cracks subjected to mode I loading under small scale yielding. However, there is little evidence for the reliability of such a criterion. On the contrary, it is shown that a local criterion is not applicable and that directional stability generally depends on body and load geometry as wel

Energy loss and flow of heavy quarks in Au+Au collisions at root s(NN) = 200 GeV

The PHENIX experiment at the BNL Relativistic Heavy Ion Collider (RHIC) has measured electrons with 0.3 < p(T) < 9 GeV/c at midrapidity (y < 0.35) from heavy-flavor (charm and bottom) decays in Au + Au collisions at root s(NN) = 200 GeV. The nuclear modification factor R-AA relative to p + p collisions shows a strong suppression in central Au + Au collisions, indicating substantial energy loss of

Screening for copy-number alterations and loss of heterozygosity in chronic lymphocytic leukemia-A comparative study of four differently designed, high resolution microarray platforms.

Screening for gene copy-number alterations (CNAs) has improved by applying genome-wide microarrays, where SNP arrays also allow analysis of loss of heterozygozity (LOH). We here analyzed 10 chronic lymphocytic leukemia (CLL) samples using four different high-resolution platforms: BAC arrays (32K), oligonucleotide arrays (185K, Agilent), and two SNP arrays (250K, Affymetrix and 317K, Illumina). Cro

Costs and outcomes for patients with rheumatoid arthritis treated with biological drugs in Sweden: a model based on registry data

Objective: To design an economic model describing the costs and outcomes for patients treated with tumour necrosis factor alpha ( TNF alpha) inhibitors for rheumatoid arthritis ( RA) in current clinical practice in Sweden, to be used as a tool to estimate cost- effectiveness of the next generation of treatments. Methods: The model was constructed as a discrete event simulation ( DES) model analyse

Effective Charges in the fp Shell

Following the heavy-ion fusion-evaporation reaction S-32+Mg-24 at 95 MeV beam energy the lifetimes of analogue states in the T-z=+/-1/2 A=51 mirror nuclei Fe-51 and Mn-51 have been measured using the Cologne plunger device coupled to the GASP gamma-ray spectrometer. The deduced B(E2;27/2(-)-->23/2(-)) values afford a unique opportunity to probe isoscalar and isovector polarization charges and to d

Conformational Disorder and Energy Migration in MEH-PPV with Partially Broken Conjugation.

In order to obtain a better understanding of the role of conformational disorder in the photophysics of conjugated polymers the ultrafast transient absorption anisotropy of partially deconjugated MEH-PPV has been measured. These data have been compared to the corresponding kinetics of Monte Carlo–simulated polymer chains, and estimates of the energy hopping time and energy migration distances for

Bryophyte conservation for the future.

he conservation process involves recognizing and listing rare and decreasing species, recording their distribution, biology and specific threats, proposing conservation programmes, and executing these programmes. There are large gaps in our knowledge about bryophytes which must be filled before their conservation can be selective. These include taxonomy, bryogeography, habitat demands, natural dy
