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...

ISO 9000 is the most popular and widely adopted meta-standard for quality and operational improvements. However, only limited empirical research has been conducted to examine the impact of ISO 9000 on operational performance based on objective and longitudinal data. To reveal any causal relationship between the adoption of ISO 9000 and operational performance, we examined the timing and magnitu...

The effects of selective beta-adrenergic receptor agonist isoproterenol (Iso) on neuronal excitability and synaptic transmission were investigated in brain slices of rat amygdala. Iso (15 microM) produced a long-lasting enhancement of the EPSP that was not blocked by pretreatment with 20 microM D-2-amino-5-phosphonovalerate (D-APV) alone or D-APV in combination with kynuretic acid (1 mM). The s...

Image synthesis is an important area in image processing. To synthesize images various systems are proposed in the literature. In this paper, we propose a bio-inspired system to synthesize image and to study the generating power of the system, we define the class of languages generated by our system. We call image as array in this paper. We use a primitive called iso-array to synthesize image/a...

The current investigation was proposed to assess the effectiveness of combination resveratrol and ascorbic acid against Isoproterenol (ISO)-induced myocardial infarction in rats. experimental model divided into six groups (n = 6 each group). Group I: control, 2: isoproterenol (ISO)-100 mg/kg b.wt, 3: ISO+Resveratrol (RES) (20 b.wt) treated, 4: ISO+ Ascorbic (AA) (80 5: ISO+RES b.wt)+AA treated ...
