We have studied the molecular specification of precursor cells in expanded neurosphere cultures derived from distinct subregions of the embryonic mouse telencephalon. These regionally derived cultures exhibited differential responses to the mitogens EGF and bFGF, suggesting that the precursors in these cultures were differentially specified as is the case in situ. To examine this further, cultures
Important constituents of extracellular matrix are collagen, fibronectin, hyaluronan, and various types of proteoglycans, such as versican, perlecan, decorin, and biglycan. Remodeling of extracellular matrix occurs continuously and is affected by various cytokines. The aim of this study was to investigate how interleukin-1beta (IL-1beta) and tumor necrosis factor-alpha (TNF-alpha), separately and
N,N'-disalicylidene-1,2-diaminopropane is a copper inhibitor present in some adhesive plasters, rubber products and gasoline. Upon contact with water it is hydrolyzed to salicylaldehyde and 1,2-diaminopropane. All patients in this study showed positive patch-test reactions to N,N'-disalicylidene-1,2-diaminopropane, and also to 1,2-diaminopropane and ethylenediamine. None reacted to salicylaldehyde
halidomide is an immunomodulating agent shown to prolong graft survival in experimental skin, renal, cardiac and bone marrow transplantation. The main purpose of the present study was to investigate the possible additive effect of combining thalidomide with cyclosporin A (CyA). Members of our group have previously created a bsis for such studies by demonstrating the ability of Linomide to abolish
The function of porcine left lung allografts was studied after perfusion with (150 mL/kg) and storage for 12 hours in a 4 degrees to 6 degrees C low-potassium-dextran solution (Perfadex; Kabi Pharmacia AB, Uppsala, Sweden). After a left lung transplantation, an artificial lung in the form of venoarterial extracorporeal membrane oxygenation was established. The artificial lung has a "biological" he
A polymer density functional theory is evaluated in terms of its ability to predict interactions between large surfaces in a polymer fluid. Comparisons are made with results from simulations in an expanded isotension ensemble. The variation of the net surface-surface interaction with adsorption strength is examined. Cases where the monomers interact via a pure hard sphere potential are investigate
Twenty-eight cases of hepatitis C virus (HCV) infection were identified in children in a pediatric oncology ward during 2 nosocomial outbreaks. HCV infection spontaneously cleared in 6 patients (21%). Eleven patients with persistent HCV viremia who had malignant diseases in remission after treatment were given a 48-week course of combined therapy with interferon-alpha (5x106 U 3 times weekly) and
OBJECTIVE: To evaluate the effect of meniscal damage on the development of frequent knee pain, aching, or stiffness in middle-aged and older adults. METHODS: The Multicenter Osteoarthritis Study is a prospective study of 3,026 individuals 50 years of age or older who have or are at high risk of developing knee osteoarthritis (OA). We investigated knees at baseline and at 15 months. Case knees (n =
The identification of the BTK(Bruton's tyrosine kinase) gene defective in human immunoglobulin deficiency X-Iinked agammaglobulinaemia (XLA) and characterisation of BTK exon-intron boundaries has now allowed the analysis of mutations and polymorphisms at the level of genomic DNA, Using Southern blot analysis and the polymerase chain reaction single strand conformation polymorphism (PCR-SSCP) assay
The aim of this study was to assess the effect of studying selected literature on dentists' decisions to remove asymptomatic, impacted lower third molars. A pre-test-post-test control group design was used. Given 36 patient cases, two groups of 16 general dental practitioners each were asked to assess the need for removal of asymptomatic impacted lower third molars. The cases were classified by th
The platelet-derived growth factors are implicated in development of fibrotic reactions and disease in several organs. We have overexpressed platelet-derived growth factor-C in the heart using the alpha-myosin heavy chain promoter and created a transgenic mouse that exhibits cardiac fibrosis followed by hypertrophy with sex-dependent phenotypes. The transgenic mice developed several pathological c
The study includes partitioning of proteins in aqueous two-phase systems consisting of the polymer dextran and the non-ionic surfactant C12E5 (pentaethylene glycol mono-n-dodecyl ether). In this system a micelle-enriched phase is in equilibrium with a polymer-enriched phase. Charges can be introduced into the micelles by the addition of charged surfactants. The charge of the mixed micelles is easi
A prospective randomized double-blind trial was performed comparing conventional low-dose heparin with a low molecular weight heparin fragment for thromboprophylaxis in elective general abdominal surgical patients. The first dose of the heparin fragment was given the evening before surgery, and further doses were given thereafter every evening. There were 1002 analysable patients, 826 having recei
Reaction of the new polydentate ligand 2,6-bis{3-[N,N-di(2-pyridylmethyl)amino]propoxy}benzoic acid (LH) with Fe(ClO4)3 followed by addition of chloroacetic acid leads to the formation of the tetranuclear complex [{Fe2OL(ClCH2- CO2)2}2](ClO4)4, the crystal structure of which reveals that it consists of two FeII2(µ-O)(µ-RCO2)2 cores that are linked via the two L ligands in a helical structure, with
Total hip replacement (THR) is a common and costly procedure. The number of THR is expected to increase over the coming years. Two pathways of postoperative treatment were compared in a randomized study. Fifty patients from two hospitals were randomized into a study group (SG) of 27 patients receiving preoperative and postoperative education programs, as well as home visits from an outpatient team
In an attempt to define clinically relevant models of akinesia and dyskinesia in 6-hydroxydopamine (6-OHDA)-lesioned rats, we have examined the effects of drugs with high (L-DOPA) vs. low (bromocriptine) dyskinesiogenic potential in Parkinson's disease on three types of motor performance, namely: (i) abnormal involuntary movements (AIMs) (ii) rotational behaviour, and (iii) spontaneous forelimb us
The aim of the present study was to evaluate in young animals the dynamics of calvarial bone healing when exposing a bone defect to continuous forces for up to 13 weeks. Six-week-old rabbits after a sagittal suture strip craniectomy were randomized for either of the following protocols: (1) no spring was applied (n = 7); (2) a titanium-molybdenum alloy (TMA) lower-force spring was inserted across
