Direct electron transfer of Phanerochaete chrysosporium cellobiose dehydrogenase at platinum and palladium nanoparticles decorated carbon nanotubes modified electrodes
In the present work, platinum and palladium nanoparticles (PtNPs and PdNPs) were decorated on the surface of multi-walled carbon nanotubes (MWCNTs) by a simple thermal decomposition method. The prepared nanohybrids, PtNPs-MWCNTs and PdNPs-MWCNTs, were cast on the surface of spectrographic graphite electrodes and then Phanerochaete chrysosporium cellobiose dehydrogenase (PcCDH) was adsorbed on the
Clinical commentary - COPD is not a systemic disease Results from the AIMAR Expert Opinion Consensus/Dissensus Seminar "COPD is/is not a systemic disease?", Venice, Italy, 13-14 November 2008
Although COPD is a major disease worldwide there is a perplexing current uncertainty about the nature of this disease. COPI) is characterized at onset and prevalently by the involvement of the lungs and bronchi, but as the disease evolves abnormalities develop in other organs and systems and the question arises: what is the pathogenesis of these respiratory and systemic impairments? Are the altera
Med hopp i hjärtat och vingar på deras hälar : Från OS i Paris 1924 till OS i London 2012 via Chariots of Fire
Artikel om den brittiska filmen Chariots of Fire från 1981, dess skildring av Paris-OS 1924, hur den avspeglar stämningar kring 1980 och hur den fick ny aktualitet i samband med London-OS 2012.
New Aspects of Alveolar Adaptive Immune Responses in COPD
Chronic obstructive pulmonary disease (COPD) is characterised by a chronic inflammation in conducting airways and the alveolar parenchyma. The inflammation, which is a consequence of inhalation of noxious gases like tobacco smoke, has traditionally been thought to be driven by innate immune responses. However, more recent studies have revealed an increase in lymphocyte-rich lymphoid aggregates (LA

20 GHz Wavelet Generator Using a Gated Tunnel Diode
We demonstrate the use of a GaAs-AlGaAs gated tunnel diode (GTD) in an ultra-wideband (UWB) wavelet generator. An inductor is integrated to form an oscillator circuit, which is driven by the negative differential conductance property of a GTD. It is demonstrated that as the gate tunes the magnitude of the output conductance, the oscillator may be switched on and off, creating short RF pulses. The
Diabetic Vascular Complications & Inflammation - role of NFAT and TNFalpha
Vascular complications of diabetes account for the majority of morbidity and mortality among diabetic patients. Large clinical trials have identified hyperglycemia as a risk factor in the development of diabetic vascular complications. The effects of hyperglycemia on the vessel wall are not fully understood, but chronic vascular inflammation has been implicated to play a major role in the pathogen

Dependence of laser accelerated protons on laser energy following the interaction of defocused, intense laser pulses with ultra-thin targets
The scaling of the flux and maximum energy of laser-driven sheath-accelerated protons has been investigated as a function of laser pulse energy in the range of 15-380 mJ at intensities of 10(16)-10(18) W/cm(2). The pulse duration and target thickness were fixed at 40 fs and 25 nm, respectively, while the laser focal spot size and drive energy were varied. Our results indicate that while the maximu
Search for direct production of charginos and neutralinos in events with three leptons and missing transverse momentum in root s=7 TeV pp collisions with the ATLAS detector
A search for the direct production of charginos and neutralinos in final states with three electrons or muons and missing transverse momentum is presented. The analysis is based on 4.7 fb(-1) of root s = 7 TeV proton-proton collision data delivered by the Large Hadron Collider and recorded with the ATLAS detector. Observations are consistent with Standard Model expectations in three signal regions
A physico-chemical characterisation of new raw materials for microcrystalline cellulose manufacturing
A detailed physico-chemical characterisation of potential new cellulose sources (rice husk, hemp stalk, and coniferous needles), and microcrystalline cellulose (MCC) manufactured from them, was made in this work. The length and the width of the cellulose crystallites were determined by wide-angle X-ray scattering (WAXS), crystallinities were studied by means of WAXS and solid state cross polarisat
Interleukin-6 concentrations in the urine and dipstick analyses were related to bacteriuria but not symptoms in the elderly: a cross sectional study of 421 nursing home residents
Background: Up to half the residents of nursing homes for the elderly have asymptomatic bacteriuria (ABU), which should not be treated with antibiotics. A complementary test to discriminate between symptomatic urinary tract infections (UTI) and ABU is needed, as diagnostic uncertainty is likely to generate significant antibiotic overtreatment. Previous studies indicate that Interleukin-6 (IL-6) in

Relationships between primary productivity and bottom-water oxygenation off northwest Africa during the last deglaciation
Abstract in UndeterminedThe upwelling region off northwest Africa is one of the most productive regions in the world ocean. This study details the response of surface-and deep-water environments off Mauritania, northwest Africa, to the rapid climate events of the last deglaciation, especially the Bolling-Allerod (15.5-13.5 ka BP) and Younger Dryas (13.5-11.5 ka BP). A high accumulation rate gravit
Multitaper Estimation of the Coherence Spectrum in low SNR
A pseudo coherence estimate using multitapers is presented. The estimate has better localization for sinusoids and is shown to have lower variance for disturbances compared to the usual coherence estimator. This makes it superior in terms of finding coherent frequencies between two sinusoidal signals; even when observed in low SNR. Different sets of multitapers are investigated and the weights of
