Background. Bioincompatible glucose degradation products (GDPs) in fluids for peritoneal dialysis (PD) develop during sterilization and storage. Their biological activity has successfully been monitored through the use of various in vitro methods but their molecular and chemical nature is less well understood. Many GDPs are highly reactive carbonyl compounds. Although some of the identified GDPs a
Although there is no biblical account of the 'Rest on the Flight into Egypt', the story is well known in the Christian world. In pseudo-Matthew the story has developed into legend form. He tells about the Christ-Child commanding the date palm Mary is resting beneath to bend down so that she can eat the fruit. It is found in literary sources from the twelfth century onwards. 'The Rest on the Flight
The adsorption and decomposition of titanium tetrachloride (TiCl4) on W(110) were studied with high-resolution core level photoelectron spectroscopy. At least two stable intermediates are formed along the pathway to TiCl4 decomposition: TiCl4(a), which is stable up to 300 K, and TiCl3(a), which is stable up to 500 K. Successive adsorption at 80 K shows that the TiCl4() species forms in the presenc
The view on reactive oxygen species (ROS) in inflammation is currently shifting from being considered damaging toward having a more complex role in regulating inflammatory reactions. We recently demonstrated a role of ROS in regulation of animal models for the autoimmune disease rheumatoid arthritis. Low levels of ROS production, due to a mutation in the Ncf1 gene coding for the Ncf1 (alias p47pho
We showed that malic enzyme and F-type ATPase isolated from glycophytes and halophytes do not differ significantly in their amino acid composition. Isolated enzymes from both types of plants showed nearly identical salt sensitivity, each, but enzyme activities in fresh homogenates from halophyte leaves apparently were more salt resistant as compared to the ones from glycophytes. These results sugg
A biphasic injectable bone substitute, suitable for filling bone defects, that sets in the body, based on calcium sulfate and hydroxyapatite (HA), is presented. For applications in bone defects the compressive strength is important to assure support of the defect site during loading when the patient is weight bearing. To control the strength, the influence of four different factors; the liquid-to-
Conditions for the introduction of terminal alkynes into the 2- and 8-positions of the Troger's base core via Sonogashira reaction of 2,8-diiodo-4,10-dimethyl-6H,12H-5,11-methanodibenzo[b,f][1,5]diazocine were established. Only the use of the bulky and electron-rich phosphine P(t-Bu)(3) as a ligand for the palladium catalyst allowed for the Sonogashira reaction to proceed effectively. In addition,
Background: Impaired nasal breathing is a risk factor for obstructive sleep apnea syndrome (OSAS). Objectives: The aim of this study was to determine whether atopy to perennial allergens and existence of perennial allergic rhinitis was a risk factor for OSAS. Methods: In a case-control study, we compared the proportions of OSAS patients with atopy to perennial allergens and perennial allergic rhin
We studied the morphology of GaP/(001)GaAs and GaAs/(001)GaP heterostructures grown by metal-organic vapour-phase epitaxy and found wire-like surface undulations elongated in the [110] direction. We attribute this elongation to anisotropic lateral growth rates in the [110] and [110] directions, which are due to a different roughness of monolayer surface steps. In III-V materials grown by molecular
OBJECTIVES: To investigate renal artery patency and renal function after deployment of aortic stents covering the orifices of renal arteries. DESIGN: Prospective open animal study. SETTING: Department of Experimental Surgery at a university hospital. MATERIALS: Twenty-three pigs were used. METHODS: Ten pigs were observed for 1 h after graft-anchoring aortic stents, Gianturco (5) and Palmaz (5), we
Let beta > 1 be a real number and M : R --> GL(C-d) be a uniformly almost periodic matrix-valued function. We study the asymptotic behavior of the product P-n(x) = M(beta(n-1)x)...M(betax) M(x). Under some conditions we prove a theorem of Furstenberg-Kesten type for such products of non-stationary random matrices. Theorems of Kingman and Oseledec type are also proved. The obtained results are appl
This report is about the co-operation between the police and the social services in the specific situation when the social services apply for assistance for taking children and drug-abusers in to involuntary care immediately. The police have an authority to use violence that social workers do not have. Therefore social workers need the police to accomplish this task. The report aims to reach adeep
The long-lived, light-induced radical Y-D(.) of the Tyr161 residue in the D2 protein of Photosystem 11 (PSII) is known to magnetically interact with the CaMn4 cluster, situated similar to 30 angstrom away. In this study we report a transient step-change increase in YD EPR intensity upon the application of a single laser flash to S, state-synchronised PSII-enriched membranes from spinach. This tran
OBJECTIVE: Endothelin (ET) has, since its discovery, increasingly been considered a key player in the pathophysiological processes of cerebral vasospasm in the course of subarachnoid hemorrhage, although it remains unclear how ET is involved. We present data that indicate an inherent capacity of human cerebral arteries to change their sensitivity to ET. METHODS: Human cerebral arteries were obtain
OBJECTIVE: Intraoperative growth hormone (GH ) measurement has earlier been tried to improve surgery for acromegaly. We calculated GH half-life after adenomectomy and evaluated the possible role of this variable in predicting the final outcome of pituitary surgery in 28 consecutive patients with acromegaly. The sensitivity, specificity and predictive values were determined in relation to the resul
