The effect of neuropeptide Y on mucociliary activity in the rabbit maxillary sinus

The effect of neuropeptide Y (NPY) on mucociliary activity in the rabbit maxillary sinus was investigated in vivo by injecting NPY at increasing dosages into the maxillary artery, response being recorded photoelectrically. At dosages of 0.1-5.0 micrograms/kg, NPY reduced mucociliary activity dose-dependently, the maximum decrease being 14.6 +/- 1.8%, at a dosage of 5.0 micrograms/kg. The NPY-induc

Modified phthalocyanines for efficient near-IR sensitization of nanostructured TiO(2) electrode.

A zinc phthalocyanine with tyrosine substituents (ZnPcTyr), modified for efficient far-red/near-IR performance in dye-sensitized nanostructured TiO(2) solar cells, and its reference, glycine-substituted zinc phthalocyanine (ZnPcGly), were synthesized and characterized. The compounds were studied spectroscopically, electrochemically, and photoelectrochemically. Incorporating tyrosine groups into ph

Response surfaces for climate change impact assessments in urban areas

Assessment of the impacts of climate change in real-world water systems, such as urban drainage networks, is a research priority for IPCC (intergovernmental Panel of Climate Change). The usual approach is to force a hydrological transformation model with a changed climate scenario. To tackle uncertainty, the model should be run with at least high, middle and low change scenarios. This paper shows

Abstract in German Handekzeme sind sehr häufig, können verschiedene Ursachen haben und trotz einer Vielzahl von Behandlungsoptionen, die von topischen Kortikosteroiden über Phototherapie bis zur oralen Gabe von Ciclosporin und Retinoiden reichen, eine therapeutische Herausforderung darstellen.

Effects of calcium and substrate on force-velocity relation and energy turnover in skinned smooth muscle of the guinea-pig

Mechanical properties and rate of ATP breakdown (JATP) have been determined in the chemically skinned guinea-pig taenia coli at 22 degrees C. The influence of varied [Ca2+], [Mg ATP] and muscle length were investigated. The shortening response after a step decrease in force (isotonic quick release) was highly curvilinear in the first 100-200 ms. This effect was shown to be a time-dependent respons

Reference data representative of normal findings at three-dimensional power Doppler ultrasound examination of the cervix from 17 to 41 gestational weeks.

Objectives To develop normal reference ranges for cervical volume and vascular indices using three-dimensional (3D) power Doppler ultrasonograpby from 17 to 41 gestational weeks. Methods This was a cross-sectional study of 352 nulliparous and 291 parous women who delivered at term and underwent transvaginal 3D power Doppler ultrasound examination of the cervix once at 17 to 41 weeks' gestation. We

Effect of divalent cations on pore formation and degradation of poly(D,L-lactide-co-glycolide).

Poly(D,L-lactide-co-glycolide) (PLG) is probably the biodegradable polymer most often used for polymeric controlled-release formulations. Different salts have been shown to affect the swelling and degradation of PLG, which, in turn, affect the release of encapsulated drugs. In this investigation the effect of divalent cations was especially investigated. Films of PLG were incubated in phosphate bu

Two Sides of the Same Coin: Bootstrapping the Restricted vs. Unrestricted Model

The properties of the bootstrap test for restrictions are studied in two versions: 1) bootstrapping under the null hypothesis, restricted, and 2) bootstrapping under the alternative hypothesis, unrestricted. This article demonstrates the equivalence of these two methods, and illustrates the small sample properties of the Wald test for testing Granger-Causality in a stable stationary VAR system by

Mechanical integrity of TCO films för flexible polymer-based displays

The mechanical integrity of tin-doped indium oxide (ITO) thin films sputtered onto a high temperature aromatic polyester developed for flexible display applications was investigated by means of tensile experiments equipped with electrical measurement, and carried out in-situ in an optical microscope. Attention was paid to the influence of ITO thickness, composition and crystalline microstructure,

Refined characterisation of chromosome aberrations in tumours by multicolour banding and electronic mapping resources

Acquired chromosome abnormalities in tumours often reflect pathogenetic events at the gene level. Multicolour fluorescence in situ hybridisation (FISH) with single-copy probes offers extensive possibilities to characterise chromosome breakpoints in relation to the physical map of the human genome. This approach is based on the construction of comprehensive EST- based maps, combinatorial labelling

Intestinal Bypass and Total Parenteral Nutrition: Changes in Gut Function and Morphology

Popular Abstract in Swedish POPULÄRVETENSKAPLIG SAMMANFATTNING Ett gott mål mat (enteral nutrition) och en välfungerande mag-tarmkanal från mun till brunn är för de flesta en självklarhet men för vissa mer en önskvärdhet. Vid sjukdom i tarm eller bukhåla kan det hända att ett tarmavsnitt nödga's koppla's ur den normala kontinuiteten genom anläggande av en så kallad stomi. Vid överviktskirurgi (exAbolition of enteral nutrition is sometimes required in severe illness. The primary aim of the present work has been to elucidate possible changes in intestinal morphology and motor function in absence of enteral nutrition. Total absence of enteral nutrition in an isolated intestinal segment was created by bypassing the distal ileum in a rat model. Intestinal bypass causes marked circumferential a

Quality of life after cystectomy and urinary diversion: An evidence based analysis

Purpose: We critically examined the evidence supporting the widely accepted notion that patients undergoing continent urinary tract reconstruction after cystectomy experience superior quality of life outcomes than patients receiving a conduit. Materials and Methods: Based on a comprehensive MEDLINE literature search we retrieved and evaluated all full-length articles published in the English, Fren
