Antibiotics constitute the dominant treatment of gastrointestinal infections. However, several serious side-effects are associated with extensive use of antibiotics, including spread of bacterial resistance and allergic reactions as well as potential overgrowth of pathogenic bacteria and viruses. On the other hand, there is a growing body of evidence suggesting that certain bacteria, referred to a
The physiological role of the cholecystokinin1 receptor (CCK1R) and the cholecystokinin/gastrin receptor (CCK2R) in the enzyme release from the exocrine pancreas in various mammal species has been debated. Experiments in pigs have indicated that physiological levels of cholecystokinin-33 (CCK-33) elicit pancreatic enzyme release via CCK2Rs located in the gastro-duodenal region. Since gastrin and C
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
