Coronafacic acid (CFA), the polyketide component of the phytotoxin coronatine (COR), is activated and coupled to coronamic acid via amide bond formation, a biosynthetic step presumably catalyzed by the CFA ligase (cfl) gene product. The COR biosynthetic gene cluster in Pseudomonas syringae pv. glycinea PG4180 is located within a 32-kb region of a 90-kb plasmid designated p4180A. In the present ...
Enterotoxigenic Escherichia coli (ETEC) is a leading cause of infectious diarrhea worldwide. Four categories of antigens have been commonly studied: O serogroup, H serogroup, colonization factor antigens (CFA), and toxins. A database has been complied from published reports of nearly 1,000 ETEC isolates from 18 locations and analyzed to determine the occurrence, distribution, and associations o...
This paper presents a color filter array (CFA) image indexing approach. To enhance the functionality of single-sensor consumer electronics such as digital cameras, imaging-enabled mobile phones and wireless personal digital assistants (PDAs), the proposed solution embeds the metadata information to a CFA image using a common discrete cosine transform (DCT) based watermarking scheme. Depending o...
مقدمه: علایم التهابی، ادم و هایپرآلژزی، پاسخی فیزیولوژیک به عوامل محرک است که می تواند به وسیله ی میانجی های متفاوتی مانند سایتوکاین ها القاء شود. گیاهان دارویی یکی از عوامل مهم مورد استفاده در بهبود علایم التهابی می باشند. هدف: با توجه به این مطالب و نقش il-6 در ایجاد هایپرآلژزی و ادم، هدف از این مطالعه بررسی اثرات پیش درمانی با عصاره های دو گیاه بومادران زرد و سنبله2 برروی التهاب حاد ایجاد شد...
This paper investigates the impacts and responses of macroeconomic shocks in some domestic economies in Sub-Saharan Africa over the period 1961-99; more specifically, it seeks to answer the question of whether there are any systematic differences in the responses of the CFA franc zones and the non-CFA franc zone countries to macroeconomic shocks. Based on the Blanchard-Quah methodology, we iden...
BACKGROUND The mechanisms underlying cyclin-dependent kinase 5 (Cdk5)-mediated thermal hyperalgesia induced by inflammation remain poorly understood. In the present study, we examined thermal hyperalgesia provoked by peripheral injection of complete Freund׳s adjuvant (CFA) to test for Cdk5 signaling in the spinal dorsal horns of rats through the p38 mitogen-activated protein kinase (p38 MAPK) s...
Deoxycytidine kinase (dCK), a rate-limiting enzyme in the cytosolic deoxyribonucleoside (dN) salvage pathway, is an important therapeutic and positron emission tomography (PET) imaging target in cancer. PET probes for dCK have been developed and are effective in mice but have suboptimal specificity and sensitivity in humans. To identify a more suitable probe for clinical dCK PET imaging, we com...
BACKGROUND Our previous studies have shown that complete Freund's adjuvant (CFA)-induced masseter inflammation and microinjection of the pro-inflammatory cytokine interleukin-1β (IL-1β) into the subnucleus interpolaris/subnucleus caudalis transition zone of the spinal trigeminal nucleus (Vi/Vc) can induce contralateral orofacial hyperalgesia in rat models. We have also shown that contralateral ...
To cause diarrhea, enterotoxigenic Escherichia coli (ETEC) must initially colonize the small bowel. Different surface structures have been implicated in this initial attachment. Recognized attachment factors include colonization factor antigens I and II (CFA/I and CFA/II) and type I pili. Several methods of detection for each of these factors have been reported. In this study, we screened for t...
The present investigation has a dual focus: to evaluate problematic practice in the use of item parcels and to suggest exploratory structural equation models (ESEMs) as a viable alternative to the traditional independent clusters confirmatory factor analysis (ICM-CFA) model (with no cross-loadings, subsidiary factors, or correlated uniquenesses). Typically, it is ill-advised to (a) use item par...
