خلاصه: دیروفیلاریا ایمیتیس ( Dirofilaria immitis ) عامل بیماری فیلاریوز قلبی عروقی در سگ و انسان است. این بیماری انتشار جهانی دارد ولی آلودگی در نواحی معتدل، گرمسیری و نیمه گرمسیری به صورت بومی دیده میشود. آلودگی به کرم قلب را میتوان با آزمایش خون و نشان دادن میکروفیلرهای در گردش و یا پادگنهای کرم بالغ تشخیص داد. به منظور ارزیابی کارایی روشهای متداول در تشخیص دیروفیلاریوز، در این مطالعه...

Background In the early 20 century, California produced only little lettuce . For 1909, Knott and Tavernetti [4] reported that lettuce was produced on 595 acres in California, which corresponded to 11% of the total U.S. acreage. Lettuce production increased dramatically in the 1920s (Figure 1). While 6,100 acres were harvested in 1919 , the harvested area reached 112,000 acres by 1930 . The mar...
هدف بررسی حاضر که مدت یکسال از تابستان 1377 شروع شد، مطالعه فیلاریوز سگهای اطراف تهران به فیلرهایی بود که میکروفیلر آنها در خون مشاهده می شود . برای این منظور از 138 قلاد سگ از شهرها و شهرکهای واقع در نواحی جنوب ، جنوب غربی ، جنوب شرقی ،شمال غربی و شمال شرقی تهران خونگیری به عمل آمد . خونها با استفاده از روش تکمیل شده نات ( Modified Knott technigue) آزمایش گردید . میکروفیلهای موجود شمارش شده و ...
background: dirofilaria immitis is a common nematode of the cardiovascular system, which infects carnivores all over the world. the infection is prevalent in dogs, but in cats and human is rare. dirofilariosis is transmitted by mosquitoes. cats are accidental hosts and are naturally resistant to the infection, compared to the dogs. mild infection can cause severe illness in cats and may lead to...
The goal of this paper is to present the methodology of constructing a language ontology of ‘coherent relations’. We construct an ontology of more abstract concepts by combining an upper-level ontology and a middle-level ontology. At the former we use theoretical considerations following Sanders et al. (1992, 1993), and at the latter we use lexical items through the substitutability test of Kno...
This paper investigates whether the model of local rhetorical coherence suggested in Knott et al. (2001) can boost the performance of the Centering-based metrics of entity coherence employed by Karamanis et al. (2004) for the task of information ordering. Our results indicate that (a) the simplest metric continues to perform better than its competitors even when local rhetorical coherence is ta...
She persuaded Vodacom Foundation Chairman, Mthobi Tyamzashe (himself born with a cleft lip), to sit in on one infant’s life-changing operation, in spite of his deep aversion to hospitals. To make doubly sure, Naiker got Vodacom’s then CEO, Alan Knott-Craig (who spent the first 5 years of his life in leg calipers and much later suffered a life-changing near-fatal heart attack), to attend a subse...
Fernstrom & Wurtman (1971) showed that re-feeding starved rats with a protein-free meal led to a rise in brain tryptophan and 5-hydroxytryptamine concentrations, and an increase in the total serum tryptophan. The rate-limiting factor in brain S-hydroxytryptamine synthesis is considered to be the availability of tryptophan in the brain; this in turn is regulated, not by the total serum tryptopha...
