The fatty acid (FA) profiles of the myxobacteria Stigmatella aurantiaca and Myxococcus xanthus were investigated by acidic methanolysis of total cell extracts and GC or GC-MS analysis. The main components were 13-methyltetradecanoic acid (iso-15:0) and (Z)-hexadec-11-enoic acid (16:1, omega-5 cis). The biosynthesis of iso-FAs was investigated in several feeding experiments. Feeding of isovaleri...

Background & Aims: An abstract is the best source of information within a content. The structured abstract is the best representation of the main source. Writing an appropriate abstract requires adherence to standards of abstracting. The aim of this study wasto investigate the compliance of Persian abstracts of research papers in medical journals of universities of medical sciences (type 1) wit...

There is no doubt that the interest that ISO standard has aroused in the academic field has its parallel in industry. Up to the end of December 2009, at least 1,064,785 ISO 9001 (2000 and 2008) certificates had been issued in 178 countries and economies. The 2009 total represents an increase of 81,953 (+ 8%) over 2008, when the total was 982,832 in 176 countries and economies. On the other hand...

isovanillin and iso-acetovanillon are two phenolic components isolated from a number of plants including pycnocycla spinosa . p. spinosa extract has antispasmodic and antidiarrheal activities. however, no comparative study has been done on antidiarrheal action of isovanillin and iso- acetovanillon, so far. the aim of this study was to investigate antidiarrheal action of isovanillin and iso-acet...

introduction: providing high quality care in emergency room is highly critical. this research was planned to compare emergency room standards of the iranian ministry of health with those of iso9001 (version 2000) method: this descriptive study compared iso 9001 standards with items listed in booklet- a1 (iranian ministry of health standards for emergency departments). expert views were sought f...

An algebra homomorphism ψ from the q-deformed algebra U q (iso 2) with generating elements I, T 1 , T 2 and defining relations [I, T 2 ] q = T 1 , [T 1 , I] q = T 2 , [T 2 , T 1 ] q = 0 (where [A, B] q = q 1/2 AB − q −1/2 BA) to the extensionˆU q (m 2) of the Hopf algebra U q (m 2) is constructed. The algebra U q (iso 2) at q = 1 leads to the Lie algebra iso 2 ∼ m 2 of the group ISO(2) of motio...

This study investigated whether maximal voluntary isometric contractions (MVC-ISO) would attenuate the magnitude of eccentric exercise-induced muscle damage. Young untrained men were placed into one of the two experimental groups or one control group (n = 13 per group). Subjects in the experimental groups performed either two or 10 MVC-ISO of the elbow flexors at a long muscle length (20° flexi...

Both β adrenergic and muscarinic receptor stimulation independently potentiate arrhythmogenesis. However, the effect of simultaneous stimulation on arrhythmogenesis is not well known. The purpose of this study was to determine the temporal response of arrhythmia risk to individual and combined autonomic agonists. Guinea pig hearts were excised and Langendorff-perfused. The β adrenergic receptor...

We examined the mechanism of atrial natriuretic factor (ANF) transcription by isoproterenol (ISO), an agonist for the beta-adrenergic receptor (betaAR), in cardiac myocytes. ISO only modestly activated members of the mitogen-activated protein kinase family. ISO-induced ANF transcription was not affected by inhibition of mitogen-activated protein kinases, whereas it was significantly inhibited b...
