Background The nematode Caenorhabditis elegans is one of the popular model hosts for the study of the evolutionarily conserved mechanism of microbial pathogenesis and innate immunity. C. elegans can be effectively used to study the dynamics of polymicrobial infections. Proteus mirabilis, an opportunistic pathogen, does not cause death in C. elegans. In this study the C. elegans was pre-infected...
چکیده: استان آذربایجان شرقی با وسعت 46930 کیلومتر مربع در منتهی الیه شمال غربی ایران قرار گرفته است که از امتداد روزخانه ارس با کشورهای جمهوری آذربایجان و ارمنستان همجوار می باشد. این استان از یک طرف با قرار گرفتن در محل تلاقی البرز و زاگرس دارای دامنه ها و دره های سر سبز بوده و از طرف دیگر در محل برخورد رشته کوه های زاگرس و آرارات قرار گرفته و تحت تأثیر جریانات آب و هوایی مدیترانه ای و اطلس ش...
در راستای بررسی تاکسونومی جنس sameraria در ایران، گونه s. glastifolia که با s. stylophora قرابت زیادی نشان می دهد به عنوان گونه جدیدی برای ایران گزارش و همچنین s. elegans مترادف با s. armena شناخته می شود .یک کلید شناسایی و نکاتی در ارتباط با تشخیص افتراقی گونه ها در این جنس ارائه می شود.
Using Pinus bungeana, Platycladus orientalis, Koelreuteria paniculata and Ginkgo biloba as research objects, three open-top chambers with different ozone-concentration gradients were set up (NF, NF40 NF80) based on trunk sap-flow technology to study the difference in ozone absorption by trees under concentrations. The results showed that monthly diurnal variations of density tree species decrea...
In traditional medicine, Jasonia glutinosa (L.) DC or rock tea (RT) has been mainly used to treat digestive and respiratory pathologies but also as an antimicrobial antidepressant herbal remedy. An ethanolic extract of RT demonstrated have antioxidant anti-inflammatory effects, which may be explained by its phytochemical profile, rich in polyphenols pigments. The aim this study is investigate t...

Food and other environmental factors affect gene expression and behaviour of animals. Differences in bacterial food affect the behaviour and longevity of Caenorhabditis elegans. However, no research has been carried out to investigate whether bacteria could utilize endogenous RNAs to affect C. elegans physiology. Here we show that two Escherichia coli endogenous noncoding RNAs, OxyS and DsrA, i...
Caffeine is a widely used psychoactive substance. Studies have shown that caffeine may play a protective role in aging-associated disorders. However, the mechanisms by which caffeine modulates aging are not yet clear. In this study, we have shown that caffeine increases Caenorhabditis elegans lifespan, delays its larval development, reduces reproduction and body length. These phenotypes were pa...
A field study was conducted in date palm orchards Salah al-Din Governorate during the period from 1/10/ 2020 to 30/10/2021 survey species of borers and estimate their population density relative presence period. The results showed diagnosis three belonging Coleoptera family Scarabaeidae, which included Oryctes elegans, Pentodon sp Tanyproctus sp. males females for (53.00, 47.00%), (51.98, 48.02...
Scientific research experiences are beneficial to students allowing them gain laboratory and problem-solving skills, as well foundational skills in a team-based setting. We designed module provide guided experience stimulate curiosity, introduce experimental techniques, with needed for higher levels of inquiry. In this module, learn about RNA interference (RNAi) codon optimization using the org...
