Frankl, P. and Z. Filredi, A sharpening of Fisher’s inequality, Discrete Mathematics 90 (1991) 103-107. It is proved that in every linear space on v points and b lines the number of intersecting line-pairs is at least (z). This clearly implies b 2 v.
Six commercially available bacterial identification products were tested with Vibrio alginolyticus (12 strains), V. cholerae (30 strains), Photobacterium (Vibrio) damselae (10 strains), V. fluvialis (10 strains), V. furnissii (4 strains), V. hollisae (10 strains), V. metschnikovii (9 strains), V. mimicus (10 strains), V. parahaemolyticus (30 strains), and V. vulnificus (10 strains) to determine...
An in-depth analysis of the mechanism of the L-type Ca(2+) current [I(Ca(L))] stimulation induced by myricetin was performed in rat tail artery myocytes using the whole-cell patch-clamp method. Myricetin increased I(Ca(L)) in a frequency-, concentration-, and voltage-dependent manner. At holding potentials (V(h)) of -50 and -90 mV, the pEC(50) values were 4.9 +/- 0.1 and 4.2 +/- 0.1, respective...
The HPLC system was equipped with a Waters XBridgeTM C18 column (2.1 × 150 mm, 5 μm), and the column temperature was set to 25 °C. The mobile phases for metabolic fingerprinting consisted of 0.1% formic acid in Milli-Q water and 5 mM ammonium acetate in Milli-Q water (solvent A, positive electrospray ionization (ESI+) and negative electrospray ionization (ESI–), respectively), acetonitrile (sol...
This current study was conducted to investigate the optimal fabrication variable that would give desirable properties in designing hydrogel wound dressings. new PVA/chitosan loaded with Chromolaena odorata were fabricated using solvent-casting method. Variables including PVA concentration (3, 5, 7 and 10% w/v), chitosan (1, 2, 3, 4 5% w/v) PVA/Chitosan ratio (10:90, 30:70, 50:50, 70:30 90:10) i...
روش سطح پاسخ برای مطالعه تاثیر عوامل ضد قهوه ای شدن (اسید سیتریک، اسید اگزالیک، کلریت سدیم، متا بی سولفیت سدیم) و آبگیری اسمزی (غلظت و زمان غوطه وری) بر روی رنگ و خصوصیات رئولوژیکی حلقه های سیب نیمه مرطوب بکار گرفته شد. پارامترهای انتخابی برای ارزیابی رنگ دلتا ای، b، a، l و امتیاز حسی رنگ و پارامترهای انتخابی برای ارزیابی بافت ریشه دوم g و g و امتیاز حسی بافت بود. نتایج بهینه سازی عددی نشان می ...
The purpose of this review was to evaluate the accuracy of SPECT in acute pulmonary embolism. Sparse data are available on the accuracy of SPECT based on an objective reference test. Several investigations were reported in which the reference standard for the diagnosis of pulmonary embolism was based in part on the results of SPECT or planar ventilation-perfusion (V/Q) imaging. The sensitivity ...
