Summary. The international MRI expert subgroup of the International Prophylaxis Study Group (IPSG) has developed a consensus for magnetic resonance imaging (MRI) scales for assessment of haemophilic arthropathy. A MRI scoring scheme including a 10 step progressive scale and a 20 step additive scale with identical definitions of mutual steps is presented. Using the progressive scale, effusion/haema
The lasting effects of a recruitment maneuver (RM) in the injured lung are not well characterized. We speculated that the reduction in respiratory elastance (H) after a deep inflation (DI) is transient in nature and should be sustained longer at higher positive end-expiratory pressure (PEEP). Thirteen ventilated mice were given 2 DIs at various levels of PEEP before and after saline lavage. Forced
The paper presents the control server, a real-time schedulingmechanism tailored to control and signal processing applications. Acontrol server creates the abstraction of a control task with aspecified period and a fixed input-output latency shorter than theperiod. Individual tasks can be combined into more complexcomponents without loss of their individual guaranteed fixed-latencyproperties. I/O o
Intramyocellular triacylglycerol (TG) is an important energy store, and the energy content of this depot is higher than the energy content of the muscle glycogen depot. It has recently been shown that the mobilization of fatty acids from this TG pool may be regulated by the neutral lipase hormone-sensitive lipase (HSL). This enzyme is known to be rate limiting for intracellular TG hydrolysis in ad
BACKGROUND: Renal failure in cirrhotic patients is a severe complication and endotoxemia might be involved. We investigated the effect of endotoxin on renal function of cirrhotic rats and the potential protective role of N-acetylcysteine (NAC). MATERIAL/METHODS: Hepatic cirrhosis was generated in a rat model by carbon tetrachloride. Both cirrhotic and normal rats were insulted by endotoxin intrave
We aimed to determine plasma and cerebrospinal fluid (CSF) levels of angiotensin-converting enzyme (ACE) and the soluble forms of intercellular adhesion molecule-1 (sICAM-1), vascular cell adhesion molecule-1 (sVCAM-1) and platelet endothelial cell adhesion molecule-1 (sPECAM-1) as surrogate markers for endothelial cell activation in clinically diagnosed patients with Alzheimer's disease (AD, n=26
Objective. To determine the potential role of the CD24 A57V gene polymorphism in systemic lupus erythematosus (SLE). Methods. We studied 3 cohorts of Caucasian patients and controls. The Spanish cohort included 696 SLE patients and 539 controls, the German cohort included 257 SLE patients and 317 controls, and the Swedish cohort included 310 SLE patients and 247 controls. The CD24 A57V polymorphis
Antibodies provide some protection against cytomegalovirus-mediated disease. All aspects of antibody recognition of important viral antigens are however not fully appreciated. Glycoprotein B (gB), a key protein in the viral membrane, participates in viral infection and it is a component of prototype vaccines. By using combinatorial antibody library and selection technology, novel antibody specific
Background: By pre-synaptic stimulation of DA(2)-dopaminergic and alpha(2)-adrenergic receptors, nolomirole inhibits norepinephrine secretion from sympathetic nerve endings. We performed a clinical study with nolomirole in patients with heart failure (HF). Methods: The study was designed as a multicentre, double blind, parallel group trial of 5 mg b.i.d. of nolomirole (n=501) versus placebo (n=499
Ferrochelatase (EC 4.99.1.1), the terminal enzyme in the heme biosynthetic pathway, catalyzes the insertion of Fe2+ into protoporphyrin IX, generating heme. In vitro assays have shown that all characterized ferrochelatases can also incorporate Zn2+ into protoporphyrin IX. Previously Zn2+ has been observed at an inner metal binding site close to the porphyrin binding site. Mg2+, which stimulates Zn
The heat shock proteins (HSPs) HSP70 and gp96 from necrotic tumour cells are considered to function as chaperones in presenting tumour antigens. We therefore studied HSP70 and immune cells in a transplantable carcinoma in the liver of rats after interstitial laser thermotherapy (ILT). Experiments were performed in Wistar FU rats using a dimethyl-hydrazine-induced adenocarcinoma implanted into the
Spatial and temporal variations in polychlorinated biphenyl (PCB) concentrations were studied in precipitation at 11 sampling-sites over a period of 1 year and compared with PCB concentrations in the air. The study was carried out in a region of southern Sweden approximately 11 000 km2 in area. The PCB concentration in precipitation ranged between 1.18 and 81.4 ng l(-1). Two of the sampling sites
We have developed a method to dock a transition-state structure into the active site of an enzyme. Such an approach is more discriminative than standard docking when looking for substrates of an enzyme, because a transition state has more sterical restrictions than a nonreactive state. We use an accurate and tailored force field for the transition-state for the hydroxylation reaction in cytochrome
Background: Chronic L-3,4-dihydroxyphenylalanine (L-DOPA) treatment of Parkinson's disease (PD) leads to debilitating involuntary movements, termed L-DOPA-induced dyskinesia. Striatofugal medium spiny neurons (MSN) lose their dendritic spines and cortico-striatal glutamatergic synapses in PD and in experimental models of DA depletion. This loss of connectivity is triggered by a dysregulation of in
In more than one-third of patients with a histological high-grade malignant soft tissue sarcoma metastasis develops despite local control of the primary tumour. Hence, adjuvant chemotherapy is increasingly used for these relatively chemoresistant tumours which requires improved prognostication to exclude low-risk patients from overtreatment. We assessed the value of stepwise prognostication in a s
To optimize treatment of chronic hepatitis C early identification of patients who will not achieve a sustained virological response (SVR) is desirable. We investigated hepatitis C virus (HCV) RNA kinetics at day 1 (in 15 patients; genotypes 1 and non-1, 9 and 6 respectively) at weeks 1, 4 and 12 (in 53 patients; genotypes 1 and non-1, 19 and 34, respectively) during treatment with pegylated interf
