Crystal structure of (piperidine-1-carbo-di-thio-ato-κ(2) S,S)[2-(pyridin-2-yl)phenyl-κ(2) C (1),N]palladium(II).

The title compound, [Pd(C11H8N)(C6H10NS2)], crystallizes with three similar and discrete mol-ecules in the asymmetric unit. The CNS2 donor set defines a distorted square-planar geometry around the Pd(II) atom, with very small deviations from planarity. The bidentate nature of the ligands gives fairly large deviations from the ideal 90° angles; the C-Pd-N angles are all around 81° and the S-Pd-S an

Electromagnetic scattering from geophysical targets by means of the T matrix approach: A review of some recent results

In the present contribution we review some recent work on scattering of electromagnetic waves from various geophysical targets, by means of P. C. Waterman's approach. As an introduction to the specific applications to be described, a general outline is given of the basic features of this approach, as applied to electromagnetic waves. The algebraic structure of the resulting equations for single an

Survival of cancer in patients with rheumatoid arthritis: a follow-up study in Sweden of patients hospitalized with rheumatoid arthritis 1 year before diagnosis of cancer.

Objectives. Patients diagnosed with RA have an increased risk of some cancers. However, limited data are available on the important issue of prognosis of RA patients with cancer. Methods. RA patients were identified from the Swedish Hospital Discharge Register by linkage to the Cancer Registry. Follow-up of patients was started from the date of diagnosis of cancer through year 2006. Hazard ratios

Learning System Thinking : The role of semiotic and cognitive resources

In the course of our educational life we are introduced to various subject areas, each with its specific way of representing knowledge. The challenge for the learner is to be able to think in ways that are supported by, and match, the representational format. A fundamental question for the science of learning concerns how this is achieved. In this thesis, it will be argued that by observing indivi

TRPV1-mediated itch in seasonal allergic rhinitis.

Background: Patients with allergic rhinitis may be abnormally sensitive to stimulation of the ion channel transient receptor potential vanilloid-1 (TRPV1). Aim of the study: To examine effects of various TRP ion channel activators on sensory symptoms in allergic rhinitis prior to and during seasonal allergen exposure. Methods: Nasal challenges were carried out with the TRPV1-activators capsaicin,

Bacterial surface protein L binds and inactivates neutrophil proteins S100A8/A9.

Finegoldia magna is an anaerobic bacterial species that is part of the normal human flora on all nonsterile body surfaces, but it is also a significant opportunistic pathogen causing a wide range of infections. Some isolates of F. magna that are more frequently associated with clinical infection express protein L, a surface protein containing multiple homologous domains (B1-B5) that bind Igs throu

What works for whom in a computer-mediated communication intervention in community psychiatry? Moderators of outcome in a cluster randomized trial.

Objective: An intervention to structure patient-key worker communication has been tested in a randomized controlled trial. The aim of this paper was to investigate effectiveness of the intervention in terms of moderators of effectiveness. Method: A total of 507 patients with schizophrenia were included. Moderators of effectiveness were investigated using two-way anovas. Results: Patients with a be

Clinical system for non-invasive in situ monitoring of gases in the human paranasal sinuses

We present a portable system for non-invasive, simultaneous sensing of molecular oxygen (O-2) and water vapor (H2O) in the human paranasal cavities. The system is based on high-resolution tunable diode laser spectroscopy (TDLAS) and digital wavelength modulation spectroscopy (dWMS). Since optical interference and non-ideal tuning of the diode lasers render signal processing complex, we focus on Fo

Effects of neurokinin receptor antagonists on L-dopa induced bladder hyperactivity in normal conscious rats.

PURPOSE: The urodynamic effects of intrathecal neurokinin (NK) receptor blockade on L-dopa-induced bladder hyperactivity were investigated in a rat model. MATERIALS AND METHODS: Continuous cystometry was performed in normal, conscious, female Sprague-Dawley rats. RESULTS: In rats pretreated with intraperitoneal carbidopa 50 mg./kg., intraperitoneal L-dopa 50 mg./kg. caused bladder hyperactivity th
