Many developmental systems are organised via the action of graded distributions of morphogens. In the Drosophila wing disc, for example, recent experimental evidence has shown that graded expression of the morphogen Dpp controls cell proliferation and hence disc growth. Our goal is to explore a simple model for regulation of wing growth via the Dpp gradient: we use a system of reaction-diffusio...
objective(s) anti-helicobacter pylori effects of saffron (crocus sativus l., iridacea) and its major constituents, crocin and safranal, were evaluated. materials and methods macerated aqueous and methanol extracts tested against 45 clinical isolates of helicobacter pylori, using paper disc diffusion method (ddm) on modified egg yolk emulsion agar (eye agar). four antibiotics also tested against...
licorice (glycyrrhiza glabra l.) is an important medicinal plant. in this study, the antimicrobial activities of ethanolic and aqueous extracts from licorice leaves were studied compared to root extracts activities. bacillus subtilis, enterococcus faecalis, klebsiella pneumoniae, pseudomonas aeruginosa, staphylococcus aureus and escherichia coli, and candida albicans were used as test organisms...
Ticarcillin, carbenicillin and BL-P1908, a new anti-pseudomonal semisynthetic penicillin, were subjected to several in vitro comparisons-including minimal inhibitory and lethal concentrations (MIC and MLC), effects of inoculum size, effects of buffering the media and regression analyses of MIC and disc diffusion data. Whereas ticarcillin and carbenicillin showed comparable spectra of activity, ...
Aim and Background: Meticillin resistant Staphylococcus aureus (MRSA) has become one of the major public-health concerns in recent years due to resistance to antimicrobial drugs and agents. This Study aims to diagnose of MRSA isolates by molecular and phenotypic methods and to detect of the antibiotic resistance pattern in MRSA strains in clinical patient samples in Rasht. Material and Methods...
Burkholderia pseudomallei (Pseudomonas pseudomallei) causes melioidosis, a life-threatening infection common among paddy cultivators in Southeast Asian countries. No plant materials have been investigated for its activity against B. pseudomallei. Therefore, a preliminary study was carried out using disc diffusion and minimum inhibitory concentration (MIC) methods to evaluate the anti-B. pseudom...
در این پژوهش از عصاره های گیاه nerium oleander برای بررسی اثرات بیولوژیکی استفاده شده است. این گیاه یک گیاه درمانی محسوب می-شود که در طب سنتی کاربرد های زیادی دارد. در این تحقیق عصاره های هگزانی، دی کلرو متانی ومتانولی بخش های برگ و گل این گیاه برای بررسی اثرات آنتی باکتریال، آنتی اکسیدان و سیتوتوکسیسیته استخراج شدند. به منظور بررسی اثرات آنتی باکتریال از تست های agar disc diffusion, agar well ...
BACKGROUND Although conventional magnetic resonance imaging (MRI) could provide excellent detection of morphological changes in the diagnosis of lumbar disc degeneration (LDD), it has some difficulties in discriminating minimal changes associated with early LDD before morphological or clinical alterations. Therefore, newer MRI techniques have emerged for investigation of early LDD. OBJECTIVES...
Abstract Background and objectives: Halo interference around antibiogram disc is one of the problems seen in Agar media. This study aimed at applying graded plate method to reduce this problem. Material and Methods: Forty-eight millimeter plates, before putting disc, were graded and the location of discs was determined. Instead of full disc, we used half-disc and then compared the haloe interfe...
