Occupational exposure to pesticides and bile tract carcinoma in men: results from a European multicenter case-control study

Objectives To estimate the associations between occupational exposure to pesticides and extrahepatic biliary tract carcinoma in men, a population-based case-control study was carried out. Methods Cases (n = 104), aged 35-70, diagnosed in 1995-1997, were sampled by active reporting systems from hospitals. Controls (n = 1,401) were a random sample of the general male population. Information on occup

The role of subsite +2 of the Trichoderma reesei beta-mannanase TrMan5A in hydrolysis and transglycosylation

The N-terminal catalytic module of beta-mannanase TrMan5A from the filamentous fungus Trichoderma reesei is classified into family 5 of glycoside hydrolases. It is further classified in clan A with a (beta/alpha)(8) barrel configuration and has two catalytic glutamates (E169 and E276). It has at least five other residues conserved in family 5. Sequence alignment revealed that an arginine (R171 in

HIF-mediated metabolic switching in bladder outlet obstruction mitigates the relaxing effect of mitochondrial inhibition.

Prior work demonstrated increased levels of hypoxia-inducible factor-1α (HIF-1α) in the bladder following outlet obstruction, associated with bladder growth and fibrosis. Here we hypothesized that HIF induction in outlet obstruction also switches energetic support of contraction from mitochondrial respiration to glycolysis. To address this hypothesis, we created infravesical outlet obstruction in

Professionalism and Organizational Performance in the Wake of New Managerialism

With New Public Management came the idea that public organizations should be led by professional managers, rather than by professionals. This has been referred to as new managerialism. This article explores how new managerialism may affect professional autonomy in a public organization that enjoys a high – and constitutionally protected – degree of organizational autonomy. A framework distinguishi

Tagging fast neutrons from an (241)Am/(9)Be source.

Shielding, coincidence, and time-of-flight measurement techniques are employed to tag fast neutrons emitted from an (241)Am/(9)Be source resulting in a continuous polychromatic energy-tagged beam of neutrons with energies up to 7MeV. The measured energy structure of the beam agrees qualitatively with both previous measurements and theoretical calculations.

Factors influencing the timing of spring migration in common toads (Bufo bufo)

We analysed 12 years of data on the spring migration of the common toad Bufo bufo L. to breeding ponds across 25 locations in Derbyshire, UK, to determine factors influencing the number of toads active per night. We also tested whether the timing of spring migration is predicted by annual variation in temperature or precipitation. More toads migrate in warmer temperatures and as the moon waxes, wh

Simultaneous one-dimensional fluorescence lifetime measurements of OH and CO in premixed flames

A method for simultaneous measurements of fluorescence lifetimes of two species along a line is described. The experimental setup is based on picosecond laser pulses from two tunable optical parametric generator/optical parametric amplifier systems together with a streak camera. With an appropriate optical time delay between the two laser pulses, whose wavelengths are tuned to excite two different

Intravenous Infusions of Purified Alpha-1 Antitripsyn Effectively Controls Symptoms and Reverts Muscle Biopsy Changes in an MZ Alpha-1 Antitripsyn Deficiency and Fibromyalgia Syndrome Patient

Background: An MZ phenotype alpha-1 antitrypsin [AAT] deficiency and fibromyalgia syndrome [FMS] patient participated in a trial with AAT-intravenous augmentationtherapy [AAT-IV-AT] after failure of conventional therapeutic measures. Three quadricep biopsies were performed at different stages. The first one showed large aggregates of AAT and ubiquitin in myocytes and blood vessels, and moderate mu

The emergence of mechanoregulated endochondral ossification in evolution

The differentiation of skeletal tissue phenotypes is partly regulated by mechanical forces. This mechanoregulatory aspect of tissue differentiation has been the subject of many experimental and computational investigations. However, little is known about what factors promoted the emergence of mechanoregulated tissue differentiation in evolution, even though mechanoregulated tissue differentiation,

Swedish legal professionals' opinions on child or adult witness memory-reporting capabilities: using the method of indirect comparisons

Legal professionals' opinions about the memory abilities of child and adult witnesses are important in the legal process. We surveyed 266 legal professionals (Swedish police, prosecutors, and attorneys) and 33 lay judges about their beliefs about child and adult eyewitnesses' recall and metacognitive abilities. Prior research has usually asked for direct comparisons of children and adults but this

Measurements of wound edge microvascular blood flow during negative pressure wound therapy using thermodiffusion and transcutaneous and invasive laser Doppler velocimetry

The effects of negative pressure wound therapy (NPWT) on wound edge microvascular blood flow are not clear. The aim of the present study was therefore to further elucidate the effects of NPWT on periwound blood flow in a porcine peripheral wound model using different blood flow measurement techniques. NPWT at -20, -40, -80, and -125 mmHg was applied to a peripheral porcine wound (n = 8). Thermodif

Proteome of the nematode-trapping cells of the fungus Monacrosporium haptotylum.

Many nematophagous fungi use morphological structures called traps to capture nematodes by adhesion or mechanically. To better understand the cellular functions of adhesive traps, the trap cell proteome of the fungus Monacrosporium haptotylum was characterized. The trap of M. haptotylum consists of a unicellular structure called knob that develops at the apex of a hyphae. Proteins extracted from k

Transapical versus transfemoral aortic valve implantation: a comparison of survival and safety.

Transcatheter aortic valve implantation (TAVI) is a therapeutic option for high-risk patients with aortic stenosis. Procedural mortality remains high in comparison with conventional aortic valve replacement (AVR) because patients determined for TAVI are commonly denied conventional surgery. We aimed to evaluate access-related complications between the transfemoral (TF) and the transapical (TA) app

Extension of nanoconfined DNA: Quantitative comparison between experiment and theory

The extension of DNA confined to nanochannels has been studied intensively and in detail. However, quantitative comparisons between experiments and model calculations are difficult because most theoretical predictions involve undetermined prefactors, and because the model parameters (contour length, Kuhn length, effective width) are difficult to compute reliably, leading to substantial uncertainti

Zinc(II) Complexes with Asymmetric 3,5-Substituted 1H-Pyrazoles

Two new pyrazolate-based ligands, N'-[1-(3-acetyl-4-methyl-1H-pyrazol-5-yl)ethylidene]-2-(hydroxyimino)propanehydrazide (L1) and 5-[(E)-1-(2-{(E)-2-(hydroxyimino}propanoyl}hydrazono)ethyl]-4-methyl-1H-pyrazole-3-carboxylic acid (L2), were synthesized and studied for zinc(II) complexation. A set of pH-dependent UV/Vis measurements has been performed to determine the complex formation properties of

Streptococcal inhibitor of complement-mediated lysis (SIC): an anti-inflammatory virulence determinant

Since the late 1980s, a worldwide increase of severe Streptococcus pyogenes infections has been associated with strains of the M1 serotype, strains which all secrete the streptococcal inhibitor of complement-mediated lysis (SIC). Previous work has shown that SIC blocks complement-mediated haemolysis, inhibits the activity of antibacterial peptides and has affinity for the human plasma proteins clu

Lack of Neuronal IFN-β-IFNAR Causes Lewy Body- and Parkinson's Disease-like Dementia.

Neurodegenerative diseases have been linked to inflammation, but whether altered immunomodulation plays a causative role in neurodegeneration is not clear. We show that lack of cytokine interferon-β (IFN-β) signaling causes spontaneous neurodegeneration in the absence of neurodegenerative disease-causing mutant proteins. Mice lacking Ifnb function exhibited motor and cognitive learning impairments

Direct electrochemistry and bioelectrocatalysis of a class II non-symbiotic plant haemoglobin immobilised on screen-printed carbon electrodes.

In this study, direct electron transfer (ET) has been achieved between an immobilised non-symbiotic plant haemoglobin class II from Beta vulgaris (nsBvHb2) and three different screen-printed carbon electrodes based on graphite (SPCE), multi-walled carbon nanotubes (MWCNT-SPCE), and single-walled carbon nanotubes (SWCNT-SPCE) without the aid of any electron mediator. The nsBvHb2 modified electrodes
