Low Prevalence of Oral and Nasal Human Papillomavirus in Employees Performing CO2-laser Evaporation of Genital Warts or Loop Electrode Excision Procedure of Cervical Dysplasia

Risk of human papillomavirus (HPV) transmission during laser vaporisation of genital warts or loop electrode excision procedure is controversial. An oral rinse, a nasal swabs, history of HPV-related diseases and data on HPV exposure were collected from 287 employees at departments of dermato-venerology and gynaecology in Denmark. A mucosal HPV type was found among 5.8% of employees with experience

Cellular elements for seeing in the dark: voltage-dependent conductances in cockroach photoreceptors

BACKGROUND: The importance of voltage-dependent conductances in sensory information processing is well-established in insect photoreceptors. Here we present the characterization of electrical properties in photoreceptors of the cockroach (Periplaneta americana), a nocturnal insect with a visual system adapted for dim light. RESULTS: Whole-cell patch-clamped photoreceptors had high capacitances and

The Locust Standard Brain: A 3D Standard of the Central Complex as a Platform for Neural Network Analysis.

Many insects use the pattern of polarized light in the sky for spatial orientation and navigation. We have investigated the polarization vision system in the desert locust. To create a common platform for anatomical studies on polarization vision pathways, Kurylas et al. (2008) have generated a three-dimensional (3D) standard brain from confocal microscopy image stacks of 10 male brains, using two

Sharing Secrets : Explaining International Intelligence Cooperation

Why has multilateral cooperation developed in the intelligence field? Prior research has deemed such cooperation unlikely, irrelevant or even dangerous due to low gains and high risks. However, multilateral intelligence cooperation both exists and seems to be on the increase. This study aims to explain this puzzling development. Drawing on institutional theory, the author advances a model of inter

Mortality from peptic ulcer bleeding: the impact of comorbidity and the use of drugs that promote bleeding.

Summary Background Use of drugs promoting peptic ulcer bleed has increased several folds. Aim To make a time-trend analysis of peptic ulcer bleed patients and evaluate the impact of age, gender, comorbidity and use of drugs promoting peptic ulcer bleed on outcome. Methods Retrospective review of hospitalizations for peptic ulcer bleed at Lund University Hospital during 1984, 1994 and 2004. Univari

Self-Rated Attentiveness Interacts with Transcranial Direct Current Stimulation and Noise Stimulation in Reaction Time in a Go/No-Go Task.

Previous research has found that stimulating inattentive people with auditory white noise induces enhancement in cognitive performance. This enhancement is believed to occur due to a statistical phenomenon called stochastic resonance, where noise increases the probability of a signal passing the firing threshold in the neural cells. Here we investigate whether people with low attentiveness benefit

L-DOPA-induced dopamine efflux in the striatum and the substantia nigra in a rat model of Parkinson's disease: temporal and quantitative relationship to the expression of dyskinesia.

Abstract L-DOPA-induced dyskinesia in Parkinson's Disease (PD) is associated with large increases in brain dopamine (DA) levels following drug dosing, but the precise significance of this phenomenon is not understood. Here we compare DA efflux and metabolism in the striatum and the substantia nigra (SN) in dyskinetic and non-dyskinetic animals following a standard dose of L-DOPA. Rats with 6-OHDA

Total gastrectomy causes a sustained, long-term elevation of somatostatin in plasma, independent of the mode of reconstruction in pigs.

AIM: The long-term effects of gastrectomy and various reconstructions of the gastrointestinal tract on fasting plasma levels of gastrointestinal hormones known to contribute to the control of gastrointestinal motor function were evaluated in pigs. MATERIALS AND METHODS: Domestic pigs were randomly selected to sham surgery or total gastrectomy (TG) followed by reconstruction with oesophago-jejunost
