Flavonoid treatment in patients with healed venous ulcer: flow cytometry analysis suggests increased CD11b expression on neutrophil granulocytes in the circulation

The objective was to determine the activation of white blood cells (WBCs) and endothelial cells in patients with healed venous ulcer and the influence of the standing position and of treatment with flavonoids. Ten patients with a healed venous ulcer were treated with flavonoid substance (90% diosmin), 1000 mg three times daily for 30 days. Blood samples were taken from arm and dorsal foot veins be

In vitro cellular drug sensitivity at diagnosis is correlated to minimal residual disease at end of induction therapy in childhood acute lymphoblastic leukemia

Leukemic cells from 85 children with newly diagnosed precursor B-lineage ALL were tested for in vitro drug sensitivity to a panel of anti-cancer drugs. Minimal residual disease (MRD) was measured by RQ-PCR. There was a significant correlation between MRD day 29 and in vitro sensitivity to prednisolone (p < 0.001) and doxorubicin (p = 0.01 7), drugs administered during induction therapy. In patient

Low prevalence of smoking in patients with autism spectrum disorders

Psychiatric patients are significantly more often smokers than the general population, the only known exception being obsessive-compulsive disorder (OCD) and catatonic schizophrenia. We have investigated nicotine use in subjects with autism spectrum disorders (ASD). Ninety-five subjects (25 females and 70 males) consecutively diagnosed with any ASD and of normal intelligence were included in the s

Protective effects of simvastatin on coronary artery function in swine with acute infection.

Background: The risk for coronary events may rise during acute infection. Perturbation in coronary endothelial function emerges as one important link. We investigated whether simvastatin could protect the coronary arterial function from the adverse effects of acute infection in swine. Methods: Coronary endothelium-dependent and -independent vasomotor responses were assessed by Doppler velocimetry

Effect of lipase on different lipid liquid crystalline phases formed by oleic acid based acylglycerols in aqueous systems

This study deals with the interplay between the interfacial structure of lipid liquid crystalline (1c) substrates and the lipolysis rate. Thermomyces (formerly Humicola) lanuginosa lipase (TLL) was added to lamellar (L-alpha), reversed bicontinuous cubic (C), and reversed hexagonal (H-II)1c phases, based on monoolein (MO), MO-sodium oleate (NaO), MO-oleic acid (OA), and MO-diolein (DO) with water.

Prospective controlled trial of a standardized meal stimulation test in the detection of pancreaticoduodenal endocrine tumours in patients with multiple endocrine neoplasia type 1

Background: Use of a standardized meal stimulation test has been recommended for the early diagnosis of pancreaticoduodenal endocrine tumours (PETs) in patients with multiple endocrine neoplasia type 1 (MEN 1). The diagnostic value of this test was re-evaluated. Methods: In a prospective, controlled trial 58 standardized meal stimulation tests (563 kcal) were performed in 12 patients with MEN 1 an

Gnathostome phylogenomics utilizing lungfish EST sequences.

The relationship between the Chondrichthyes (cartilaginous fishes), the Actinopterygii (ray-finned fishes) and the piscine Sarcopterygii (lobe-finned fishes), and how the Tetrapoda (four-limbed terrestrial vertebrates) are related to these has been a contentious issue for more than a century. A general consensus about the relationship of these vertebrate clades has gradually emerged among morpholo

Kinetics of ethanol production by recombinant Escherichia coli KO11

The fermentation kinetics for separate as well as simultaneous glucose and xylose fermentation with recombinant ethanologenic Escherichia coli KO11 are presented. Glucose and xylose were consumed simultaneously and exhibited mutual inhibition. The glucose exhibited 15 times stronger inhibition in xylose fermentation than vice versa. The fermentation of condensate from steam-pretreated willow (Sali

Random Feynman graphs

We investigate a class of random graph ensembles based on the Feynman graphs of multidimensional integrals, representing statistical-mechanical partition functions. We show that the resulting ensembles of random graphs strongly resemble those defined in random graphs with hidden color, generalizing the known relation of the Feynman graphs of simple one-dimensional integrals to random graphs with a

BRCA1 and BRCA2 mutations in ovarian cancer : Covariation with specific cytogenetic features

We analyzed 37 primary invasive carcinomas for BRCA1 and BRCA2 mutations by screening the entire coding regions of both genes. Seven predicted truncating mutations (four in BRCA1 and three in BRCA2) and one novel BRCA1 missense variant (S1542C) were identified (8/37, 22%). Two of the BRCA1 mutations were somatic changes, whereas the remaining three BRCA1 changes and all mutations of BRCA2 were fou

Potential effects of PKC or protease inhibitors on acute pancreatitis-induced tissue injury in rats.

Background: Acute pancreatitis (AP) is still one of the severe diseases, that cause the development of multiple organ dysfunction with a high mortality. Effective therapies for AP are still limited, mainly due to unclear mechanisms by which A-P initiates both pancreatic and extrapancreatic organ injury. Methods: Protease inhibitors (aprotinin, pefabloc, trypsin inhibitor) and PKC inhibitors (polym

Perfusion abnormalities in pulmonary embolism studied with perfusion MRI and ventilation-perfusion scintigraphy: an intra-modality and inter-modality agreement study

PURPOSE: To compare perfusion magnetic resonance imaging (MRI) and ventilation-perfusion scintigraphy (V-P scan) in the study of perfusion abnormalities in pulmonary embolism (PE) and to compare the PE results to the findings previously reported for pneumonia and chronic obstructive pulmonary disease (COPD), in terms of perfusion abnormalities. MATERIALS AND METHODS: Dynamic contrast-enhanced MR i

Heme oxygenase-1, heme oxygenase-2 and biliverdin reductase in peripheral ganglia from rat, expression and plasticity

The expression of inducible and constitutive heme oxygenase and biliverdin reductase was studied in normal and cultured peripheral ganglia from adult rats, using immunocytochemistry and in situ hybridization. Dramatic changes were induced by one to two days' culturing of dorsal root ganglia, nodose ganglia, otic ganglia, sphenopalatine ganglia and superior cervical ganglia. An up-regulation of ind

Developmental and hormonal regulation of progesterone receptor A-form expression in female mouse lung in vivo: interaction with glucocorticoid receptors

Progesterone (P-4) regulates many aspects of physiological functions via two nuclear P-4 receptors (PR), PRA and PRB, which are members of a structurally related nuclear hormone receptor superfamily that includes glucocorticoid receptors (Gk). The regulation and cellular distribution of PR protein isoforms have been extensively studied in reproductive tissues, but this is not the case in the lung.

Revascularization of the superior mesenteric artery after acute thromboembolic occlusion

BACKGROUND: The outcome and prognostic factors after revascularization of acute thromboembolic occlusion of the superior mesenteric artery (SMA) are poorly documented. METHODS: Sixty patients with acute thromboembolic occlusion of the SMA had revascularization procedures at 21 hospitals from 1987 to 1998. They were registered prospectively in the Swedish Vascular Registry. Patient files were analy

Distribution of peptidergic nerves in the choroid plexus, focusing on coexistence of neuropeptide Y, vasoactive intestinal polypeptide and peptide histidine isoleucine

Choroid plexus from rat, guinea-pig, rabbit and pig was investigated by light-microscopic immunohistochemistry and by radioimmunoassay for the presence of neuropeptides. A moderately dense supply of nerve fibers containing neuropeptide Y (NPY) and vasoactive intestinal polypeptide (VIP), respectively, was found around blood vessels and in close relation to the secretory epithelium in both pig and
