The final diagnosis was right, congenital Horner’s syndrome due to ipsilateral internal carotid agenesis. We describe in detail the radiological findings and pathophysiological mechanisms of this unusual association.”
“The aim of this work was to study the enrichment of the Gamma linolenic acid (GLA) content of lipid extracted from Mucor zychae by employing a low-temperature urea crystallization process. GLA, a polyunsaturated fatty acid has been reported to have many health benefits and has potential implications in food and pharmaceutical industry. Lipids extracted from the mycelia of fermented broth were transesterfied and analysed by gas chromatography. Results showed that
the fungal oil contained (%) myristic acid (1.2), palmitic acid (35.3), palmitoleic acid (3.7), stearic acid (2.7), oleic acid (39.2), linoleic acid (6.4) and gamma linolenic acid (8.7). After the first step of crystallization, the percentage of GLA enriched in selleck chemicals the total lipid was increased to 63.5. The concentration of GLA further increased when the enriched lipid sample was subjected to Urea crystallization for
the second time. GLA percentage increased from 63.5 to 92.7, and recovery of GLA was 63%. By altering the ratio of fatty acid ethyl ester:urea, the concentration characteristics and the recovery of GLA also varied; highest recovery of GLA (69%) was obtained when, the above ratio was 1:3. Furthermore, GLA recovery was in considerable amounts at 0 degrees C crystallization. (C) 2009 Elsevier Ltd. All rights reserved.”
“Background: Peritonitis is a common and serious complication of peritoneal dialysis (PD). Coagulase-negative staphylococci
click here from Epigenetics inhibitor the patient’s own skin flora are the most commonly found micro-organisms.
Objective: In the present study we aim to elucidate the immune response in the early stage of infection and to clarify the importance of bacterial attachment to fibrinogen.
Methods: Clinical Staphylococcus epidermidis isolates collected from PD peritonitis or the residential skin flora of healthy individuals were used to infect monocytes, macrophages, and peripheral blood mononuclear cells (PBMC) in the presence or absence of fibrinogen. The S. epidermidis strain HB (fbe(+)), expressing the fibrinogen-binding protein Fbe, and its isogenic mutant STO56 (fbe(-)) were used to study the impact of Fbe during cell infection. Immune induction was measured as interleukin-8 (IL-8) production determined by ELISA. Modulation of CD11b/CD18 expression in neutrophils incubated in conditioned medium from these experiments was analyzed in order to judge the cellular response.
Results: S. epidermidis causing peritonitis was less immunogenic compared to strains belonging to the residential skin flora, as measured by IL-8 induction in monocytes and CD11b/CD18 expression in neutrophils. At low bacterial concentrations, attachment to fibrinogen was a prerequisite for an IL-8 induction in monocytes and PBMC.
