The genus Ceratovacuna Zehntner, 1897 (Hemiptera: Aphididae: Hormaphidinae) is reviewed for the first time in China, with the descriptions of five new species, C. angusticorna Qiao sp. n., C. beijingensis Qiao sp. n., C. imperata Qiao sp. n., C. multiglandula Qiao sp. n., C. separata Qiao sp. n. and four new records for China, C. graminum (van der Goot, 1917), C. keduensis Noordam, 1991, C. pan...

We report here a human case of Taenia asiatica infection which was confirmed by genetic analyses in Dali, China. A patient was found to have symptoms of taeniasis with discharge of tapeworm proglottids. By sequencing of the mitochondrial cytochrome c oxidase subunit 1 (cox1) gene, we observed nucleotide sequence identity of 99% with T. asiatica and 96% with T. saginata. Using the cytochrome b (...

Abstract Rachiplusia nu (Guenée) (Lepidoptera: Noctuidae, Plusiinae) is a defoliator of soybean ( Glycine max L., Fabaceae), sunflower Helianthus annuus Asteraceae), alfalfa Medicago sativa and horticultural crops in temperate southern South America; however, there little genetic information available about this pest insect. Recently, concerns insect have increased because its suspected resista...

هدف: از چالش­های عمده بشریت افزایش افسردگی و اختلال عملکرد جنسی ناشی داروهای ضدافسردگی است. با توجه به نقش سلول­های سرتولی در اسپرماتوژنز، پژوهش حاضر، اثر داروی دولوکستین را بر زنده­مانی، آپوپتوزیس بیان ژن­های Bax و­ (Connexin 43) Cx43 بررسی کرده مواد روش‌‌ها: TM4 محیط DMEM/F12 حاوی %5/2 FBS، 5% سرم اسب %1 پنی سیلین-استرپتومایسین کشت شدند. دوزهای 30،60، 15، 5/7، 75/3 میکرو­گرم/ میلی­لیتر زمان­ه...

BACKGROUND Sparganosis caused by invasion of the plerocercoid larvae (spargana) of Spirometra erinaceieuropaei have increased in recent years in China. However, the population genetic structure regarding this parasite is still unclear. In this study, we used the sequences of two mitochondrial genes cytochrome b (cytb) and cytochrome c oxidase subunit I (cox1) to analyze genetic variation and ph...
